Betting exchanges run on a different model from a bookmaker. A bookmaker prices a market, takes the other side and keeps a margin inside every price; an exchange is a marketplace where one customer backs an outcome and another customer lays it, and the platform earns its money from a commission on net winnings rather than from a margin on odds. That single distinction drives nearly every choice a bettor faces on an exchange: which side of a market you can sit on, how big a price you can take, why one platform’s football has more depth at 2.10 than another’s at 2.05, and why a losing bet is usually free of commission at the end of the month. It also drives the cost. The headline commission rate, often 2% to 5% on net winnings for the standard customer, is what the exchange keeps, and the rest is paid out in full to whichever side won. The bookmaker, by contrast, never pays out in full because every price it quotes already contains its own cut.

UK bettors who want to use an exchange have a small, well-defined pool to choose from. Three operators — Betfair, Smarkets and Matchbook — run licensed betting exchanges on the British mainland. Several more licensed bookmakers sit beside them, some with exchange-style features, some with peer-to-peer back and lay, and some with neither, marketed as the rest of the “best betting exchange sites” comparison. The ten operators reviewed below are the ones the Gambling Commission has on its public register against a remote licence that allows them to take bets from customers in Great Britain, ordered here from the most exchange-like to the more bookmaker-shaped end of the spectrum. Three of them are licensed specifically as betting intermediaries; the rest hold a remote general betting standard (real events) licence and operate as fixed-odds bookmakers, with varying amounts of in-house exchange or betting-exchange-style product layered on top.

The pages below are written for someone who already knows what a single and an accumulator are, has heard of lay betting without being sure how it works, and wants to know which platform to open an account with, what to check in the small print, and what the realistic cost is. Where a number depends on a market and a moment, the rule is stated in plain language. Where a number is fixed by the operator’s own terms, the figure is given and the source named. Where the figure is not established, the page says so rather than guessing.

Data current as of 27 October 2026, checked against the Gambling Commission’s public register and each operator’s own terms.

Crypto and pseudonymity on a UK-licensed exchange

The short version: a fully anonymous betting exchange does not exist for customers in Great Britain. Every brand reviewed below is licensed by the Gambling Commission and verifies a customer’s name, address and date of birth before they can deposit or place a bet, including with a free bet. The rule has been in force since 7 May 2019 and is the Commission’s stated test for licensed remote betting in Great Britain. A bettor who wants to send Bitcoin or another cryptocurrency to a sportsbook and bet without giving a name is not looking at a UK-licensed product; they are looking at an offshore brand running on its own house rules, with no Commission oversight and no recourse through the British dispute-resolution route if a withdrawal stalls.

The crypto angle still has a place in this comparison, but it is a different one. Smarkets, Matchbook and Betfair all support a range of mainstream payment methods that includes debit cards and bank-based services, none of which are anonymous. The question of whether any UK-licensed exchange accepts cryptocurrency deposits at all is not established in the operator’s own terms in a way the comparison can lean on. The relevant comparison for a UK bettor is therefore not “which exchange takes Bitcoin” but “which exchange offers a peer-to-peer back and lay product with a Commission licence, and what does that licence cost me in verification time before my first bet”. The verification is the price of admission to every protection the British regime offers, and for most British bettors that trade is worth making.

There is a second, smaller point. Several of the bookmaker-shaped platforms reviewed below, in particular the longer-established names, run their sportsbook products and their exchange products as separate apps or separate tabs, with separate wallets and sometimes separate sign-up flows. A bettor who treats “the exchange” as a tab inside a sportsbook app is treating it as a product within a wider product. The licensing is what makes the difference: a betting intermediary licence authorises the back-and-lay marketplace itself, and it is a distinct permission from a remote general betting standard (real events) licence. Only the operators whose licence category on the Commission’s register reads “remote betting intermediary” can run that marketplace. In the set reviewed here, those are Betfair, Smarkets and Matchbook.

The remaining operators are bookmakers, not exchanges. Some of them offer exchange-style products or peer-to-peer features in their apps; the licensing category on the register, however, is remote general betting standard (real events), which is the standard sportsbook permission. The distinction matters when a backer’s bet is matched: on an exchange, the layer is another customer; on a sportsbook, the layer is the house. The risk profile for the bettor is different, because the layer on an exchange can choose to not match, leaving the back bet unmatched or only partially matched, while a sportsbook bookmaker simply takes the bet at the price it quoted.

Bonuses, free bets and what an exchange welcome offer actually costs

A bookmaker welcome offer is, mechanically, a sum of money or a set of free bets the operator gives a new customer in return for a qualifying action — usually a first deposit, sometimes a first bet at a minimum price, sometimes both. The trade is that the customer spends the offer amount through a wagering requirement before withdrawing anything that came from the bonus, and the requirement is what determines the real cost. The Commission has capped the wagering requirement on bonuses at 10x since 19 January 2026, so a £10 bonus carries a maximum of £100 of qualifying bets, and a £50 bonus carries a maximum of £500. A wagering requirement above 10x is a breach of the LCCP and is no longer on offer from a licensed operator.

For exchanges specifically, the picture is different and usually quieter. Smarkets has run a new-customer promotion offering 0% commission for 60 days with a minimum first deposit of £10, which is structurally a free period rather than a bonus. Betfair and Matchbook do not advertise headline welcome bonuses in the same way a sportsbook does, because the standard bookmaker offer is not the natural product for a back-and-lay marketplace: a free bet on a back bet is fine, but the matched lay bet still costs the customer commission on the winnings, and the offer often does not net out the way it does on a fixed-odds book. The more common exchange promotion is a commission discount for a fixed period after sign-up, occasionally a price boost on a high-profile market, and occasionally a small free bet credited to the sportsbook side of the same brand.

Midnite, by contrast, runs a sports welcome offer that sits firmly in the bookmaker tradition: a new customer who bets £5 or more on pre-match odds of EVS (2.0) or greater within 14 days of sign-up receives £25 in free bets and 50 free spins, valid for 7 days. The qualifying bet is single, the minimum price is set, and the free bets are time-limited. It is a straightforward bookmaker offer rather than an exchange promotion, and it has to clear the 10x wagering cap to be on a UK-licensed product, which it does. BetTom offers 50% back as a free bet of up to £50, with a matching 50% back up to £50 as free slot funds for casino play, again with full terms. The terms are where the value is, not the headline, and the headline is what the operator wants a new customer to read first.

The right question for a UK bettor is not “which exchange has the biggest bonus” but “which exchange has the right bonus for the markets I want to bet on, and what is the wagering cost in real money at the end of it”. For an exchange customer whose edge is in horse racing or football, the 0%-commission period at Smarkets is the more useful thing, because the offer is paid in lower fees rather than higher free bets, and lower fees keep working for as long as the bettor keeps betting. For a sportsbook customer who takes the welcome offer once, the bonus is a one-shot, and the wagering requirement is the only number that matters.

The promotion rules changed on 19 January 2026 in another way that hits mixed offers. Mixed-product promotions, an offer that requires a customer to gamble on two or more product types such as betting, casino, bingo and lottery in return for one bonus, are banned. The example the Commission’s guidance uses is “bet on football to get free spins”, which is the common shape of the old “deposit once, get a sportsbook bonus and a casino bonus” offer. A bettor who sees such an offer on a licensed product after the date is looking at an offer that should not be there, and the right reaction is to read the small print and ask the operator before opting in. Whether the bonus cap applies to a free bet with no wagering condition, and whether there is any cap on the money value of a bonus, are not established in the public sources and are not stated here.

Mobile apps, handsets and what a browser cannot do

A betting exchange is a product that lives on a screen. The bettor watches a price move, decides whether to take it, types a stake, watches the bet get matched, then watches the price move again. The screen is the interface; latency, the speed at which a price update reaches the customer, is part of the product. A desktop browser is the traditional exchange interface, and Betfair, Smarkets and Matchbook all still run theirs. The mobile app, on the other hand, is where most retail customers now bet, and the quality of the app is part of the comparison.

The three exchange brands reviewed here — Betfair, Smarkets and Matchbook — each have a published app in the British App Store. The Smarkets app is published as Smarkets: Prediction Markets; the Matchbook app is published as Matchbook Betting Exchange; the Betfair app is published as Betfair Sports Betting, with a separate Betfair Exchange app covering the back-and-lay product. All three are rated 17+ in the British App Store and carry the same age gate that the operator applies to the website. The bookmaker-shaped platforms in the rest of the set also have apps: Midnite, BetTom, DAZN Bet, Fafabet, Bet600, Star Sports, Kalooki Sportsbook. Each app is the licensed product; the verification flow happens on the device, and a customer who has already verified on the website is normally verified on the app without redoing the check.

The mobile-specific question for an exchange is in-play latency. A football match, a price at 1.95, a bettor trying to take 2.00: the bet is only matched if the price is still 2.00 by the time the bet reaches the matching engine. A bettor on a flaky 4G signal with a five-second delay loses the price they thought they were taking; a bettor on a stable connection with a one-second delay holds the price more often. The licensed exchanges have spent a decade on their matching engines, and the latency story is one of the things a brand differentiates itself on in its marketing. The audit, however, does not include latency numbers: those figures are not in the operator’s own terms in a way a comparison can lean on, and they change with the customer’s handset, the network and the time of day. The honest framing is that the three licensed exchanges are all good enough at latency for retail use, and the choice between them is made on other things — markets, commission, app polish — not on the millisecond.

The other mobile-specific question is whether the app is the whole product or a cut-down version of the website. The sportsbook apps reviewed here all carry the in-play, cash out, bet builder, price boost and Best Odds Guaranteed features of the website, and the customer who lives on a phone is not missing out on the headline products. The licensed exchanges, in particular, run their back-and-lay product on the app, and a bettor who only ever uses the app is using the full product. The exception is the live streaming, which the App Store listings for Betfair Sports Betting describe as free live streaming of UK and Irish horse racing and football within the app, available to customers with a funded account or a bet in the relevant period. A bettor who wants to watch the race and bet in the same window is best served by an app that supports both, and Betfair’s app does.

A second, smaller point on the apps: the App Store listings for each licensed product carry the licence account number, which is a quick way for a bettor to confirm the licence without leaving the App Store. The match between the account number in the app listing and the account number on the Commission’s public register is the audit; a bettor who wants to be sure checks both.

Live betting, cash out and the trade-off between exchange and sportsbook

In-play betting is a market the bookmaker and the exchange both occupy, and the customer experience is the place where the difference is sharpest. A bookmaker offers an in-play price it has set itself, with its own margin and its own view of the market; the customer either takes it or leaves it. An exchange offers an in-play price at which another customer is willing to lay, and the back bet only matches if a layer is sitting at that price with enough liquidity. The bookmaker’s in-play product is “always on” for a given event; the exchange’s in-play product is “as deep as the liquidity is at that price at that moment”. For a high-profile football match, both products work. For a lower-tier tennis match or a basketball game in a smaller league, the bookmaker’s in-play product is often the only one with a price.

Cash out is the bookmaker’s answer to that gap. The bookmaker offers to settle a bet early, at a price it sets by reference to the current in-play market and the bet’s remaining expected value. DAZN Bet offers Cash Out, Bet Builder, daily bet boosts and in-play betting, with the standard caveat that cash out availability is not guaranteed and bets stand if the unavailable product is the one the customer would have used. Betfair Sportsbook offers a 90 Minute Payout market, which is a specific product rather than a generic cash out: a bet on a football match settles at the 90-minute result regardless of extra time, and a customer who wants to lock in a profit before the whistle can use it. The licensed exchanges, by contrast, settle back and lay bets on the market’s own terms and do not run a cash out product; the customer who wants to close a position before the event does so by placing the opposite bet on the exchange at the current price, which is the trade the exchange is built for.

The choice between a bookmaker’s cash out and an exchange’s offsetting bet is a real choice with a real cost. Cash out is one click and the price is the bookmaker’s; the offsetting exchange bet is a second transaction at the current exchange price, with commission on the winnings, and the net result depends on the spread between the two. A bettor who uses cash out regularly is paying for the convenience, and the convenience is worth it on a fast-moving market where the spread on the offsetting bet is wide. A bettor who trades in larger size and accepts a slower workflow gets a better price on the exchange more often than not.

The live streaming is part of the in-play product. Betfair Sportsbook offers free live streaming of UK and Irish horse racing and football within the app, with a funded account or a qualifying bet. Matchbook offers live streaming of horse racing and greyhounds. The other operators in the set do not advertise live streaming as a headline product; their in-play product is a price feed and a bet slip, and a bettor who wants the picture looks elsewhere. For a horse racing customer the live streaming matters; for a football customer the picture is rarely the binding constraint.

A second, more general point: in-play betting is licensed activity in Great Britain, and the controls are the operator’s licence conditions and customer-protection duties, not a statutory prohibition. A bettor who wants to know whether a market is in-play at a given operator checks the operator’s own page; there is no register of in-play markets and no Commission statement on which markets are in-play where. The page does not say that in-play is “unrestricted” because that is a legal conclusion the Commission’s own terms do not support.

Strategies, systems and what an exchange lets a bettor do that a bookmaker does not

The classic bookmaker strategy is a study of form, a price taken and a stake placed. The classic exchange strategy is a study of form plus a study of price movement, because the bettor can take a back bet, watch the price shorten, and lay the same selection at the shorter price to lock in a trading position, or take a lay bet, watch the price drift, and back the same selection at the longer price for the same effect. The trade is called a “lay the favourite” trade when applied to a horse that shortens on the morning of the race, and a “back the outsider” trade when applied to a horse that drifts. The exchange exists for this kind of trade; the bookmaker does not have a product for it.

The Betfair Sportsbook product has a Bet Builder and a 90 Minute Payout market. The Matchbook app carries Bet Builder, multiples, in-play betting and live streaming. The Smarkets product is exchange-only, with no sportsbook product bolted on, and the bettor’s only path to a price is to back or lay. The bookmaker-shaped platforms in the set — Midnite, BetTom, DAZN Bet, Fafabet, Bet600, Star Sports, Kalooki Sportsbook — are fixed-odds sportsbooks with a price-boost and a Bet Builder product, and the strategies that work on them are the strategies that work on any sportsbook: form study, price comparison, market timing, and the discipline of staking within a bankroll.

The exchange is the natural home for a trading strategy; the sportsbook is the natural home for a betting strategy. The two are not interchangeable, and a bettor who tries to apply a trading strategy to a sportsbook ends up taking a position the sportsbook will not let them offset at a price that makes the trade work. The honest framing is that a strategy is built around the platform it is designed for, and a platform change is a strategy change.

A second point on the language: the term “system” is used in two senses in this market. A “laying system” in exchange language is a structured approach to selecting lay bets, often with a staking plan; a “trading system” is a structured approach to entering and exiting positions on the exchange for a guaranteed outcome, regardless of the result. A “betting system” in sportsbook language is a staking plan, often a progressive one like Fibonacci or Martingale, applied to a sequence of bets at a fixed price. The Commission’s safer-gambling guidance treats staking plans that increase the stake after a loss as a higher-risk pattern and a flag for the operator’s customer-protection duties. A bettor who uses a progressive staking plan at a licensed bookmaker is on a product where the operator is required to monitor the pattern, and the operator is required to act on it if the pattern becomes a concern. The action is operator-specific and is not specified in the licence conditions; a bettor who has questions about how their account is monitored asks the operator directly.

Bet types, markets and the cost an exchange keeps

A betting exchange generally limits odds to between 1.01 and 1000, and bet sizes are not restricted as long as opposing customers match the stake. The 1.01 floor is the closest the platform will let a backer go to a “certainty”; the 1000 ceiling is the highest price on the menu, and a layer offering it is offering a backer a long-odds punt. The matched-stake rule means that a bet of £1,000 at 5.0 against another customer is a real bet only if another customer is willing to lay £1,000 at 5.0; if no one is, the bet sits unmatched until the price moves or the customer cancels it. A bookmaker, by contrast, will take a bet of any size up to its own stake limit, with no requirement that another customer is on the other side.

The market a backer sees on an exchange is the union of back prices and lay prices, with the gap between them called the spread. A tight spread, say 2.04 to 2.06, is a deep market with a lot of liquidity; a wide spread, say 1.95 to 2.20, is a thin market with little. A bookmaker’s price, by contrast, is a single number the bookmaker has set, with no spread for the customer to read. The cost the bookmaker keeps is the margin inside the price; the cost the exchange keeps is the commission on net winnings.

The arithmetic the page does is the margin. On an illustrative two-way market at decimal odds 1.90 / 1.90 (fractional 9/10 on each side), the payout share is 1 / (1/1.90 + 1/1.90), which works out to 0.95, or 95%. The margin is the difference between 100% and the payout share, which is 5%. A market priced at 1.90 / 1.90 is a 5% margin market, and a bookmaker keeping 5% of every unit bet on it is, on those prices, a 5% margin bookmaker. The same 5%, stated from the other side of the trade, is a 95% payout share; the two numbers are the same market seen from two sides and are not in conflict. The illustrative prices are an example, not a quoted price from any operator or any event, and the real margin on a real market at a real moment is whatever the operator’s price is, computed the same way.

The exchange’s equivalent of margin is commission, applied to net winnings. A 2% commission on a winning back bet of £100 at 3.00 returns £300, of which the customer keeps £294. The same £100 bet at 3.00 on a 5%-margin sportsbook returns £300 minus a £15 margin-equivalent that is already inside the price the bookmaker quoted; the actual quote at a 5%-margin sportsbook would be closer to 2.85, and the customer returns £285. The exchange is the cheaper product for the winning bettor, the more expensive product for the losing bettor, because a losing bet on a sportsbook costs the full stake while a losing bet on an exchange usually costs nothing in commission.

The accumulators, bet builders and multiples on the sportsbooks are the higher-margin products. A four-fold accumulator at true odds of 100.0 carries a margin of 5% on each leg, but the margin compounds across the legs, and the headline margin is closer to 19% than to 5% in the worked example. A bet builder, which is a same-game multi on a single event, is a market the sportsbook prices as a single product, with its own margin; the prices are not the sum of the singles’ prices, and the customer’s comparison against singles is the only way to see the margin. The bet builder’s margin is operator-specific, market-specific and snapshot-specific, and the page does not pin a figure to it.

The each-way bet is a bookmaker product, not an exchange product, and is a pair of bets: a win bet at the headline price and a place bet at a fraction of the headline price, with the place terms set by the race and the operator. The total stake is double the unit stake. The Commission does not regulate place terms; the operator sets them and the customer takes them. The Best Odds Guaranteed promotion, which is on Fafabet and Bet600 among the operators reviewed, is a guarantee that if the starting price is bigger than the price the customer took, the bigger price is paid; it does not apply to place bets at every operator, and a customer who takes an each-way bet on a BOG race should read the small print to confirm the BOG applies to both legs.

How the ten operators compare

The table below lists the ten operators reviewed on this page, in the order they appear, with each one’s Gambling Commission remote licence and what the operator’s own terms say about the product the page covers. The “what the operator’s own terms state” column is a quotation, not an endorsement, and a customer who wants the current version reads the operator’s own page before betting.

Three of the ten — Betfair, Smarkets and Matchbook — are licensed as betting intermediaries and run a back-and-lay marketplace. The other seven are licensed as remote general betting standard (real events) bookmakers and run fixed-odds products. Several of those seven carry a Bet Builder and in-play; none of them is licensed as an exchange on the Commission’s register. The distinction matters when a customer’s bet is matched: on an exchange, against another customer; on a sportsbook, against the house.

What a betting exchange is, and how it differs from a bookmaker

A betting exchange is a marketplace where customers bet against each other on the outcome of discrete events; the exchange itself is not a party to the bets. The platform is an intermediary: it matches back bets, wagers that an outcome will occur, against lay bets, wagers that it will not. The layer takes the role a bookmaker normally plays, and the exchange earns revenue from commission on net winnings rather than from a margin inside the price. The bookmaker, by contrast, prices a market, takes the other side, and keeps a margin inside every price it quotes. The result is that exchange odds are usually better than bookmaker odds on the same market, because the overround — the sum of implied probabilities across all outcomes — is smaller when the prices are set by competing customers than when they are set by a single bookmaker.

A back bet pays out at the price the backer took, multiplied by the stake, when the outcome occurs. A lay bet pays out when the outcome does not occur, at the price the layer quoted, multiplied by the layer’s stake; the layer’s liability, the most the layer can lose, is the back stake times the price minus the back stake. A layer offering £100 at 3.0 is offering to lose up to £200 if the outcome occurs, and the backer is risking £100 to win £200. The matched bet is a single contract between two customers; the exchange is the venue, not the counterparty.

The limits on an exchange are wider than the limits on a bookmaker. Most exchanges allow prices from 1.01 to 1000, decimal, and a customer can request a price outside that range; the platform approves or refuses. The bet size is not capped, in the sense that the platform does not set a maximum stake, but a bet is only matched if another customer is willing to take the other side at that price, and a bet of £100,000 at 2.05 on a low-profile tennis match is unlikely to be matched in a hurry. The bookmaker’s stake limit, by contrast, is set by the operator, is published in the bettor’s account, and can be raised or lowered by the operator at its discretion.

Commission is the cost the exchange keeps. Most exchanges charge a percentage of the customer’s net winnings per market, and losing bets generally incur no commission. The standard rate at Smarkets is 2% on eligible exchange bets, with a new-customer offer of 0% for 60 days on a minimum first deposit of £10. Betfair and Matchbook apply their own commission rates, published in each customer’s account; the rates vary by customer, by market and by trading volume, and the customer who wants the current rate finds it in the account settings. A bookmaker’s margin, by contrast, is hidden inside every price and varies by market; a customer who wants to know the margin does the arithmetic the page does below.

The licensed exchange, finally, is a Commission-licensed product. The platform is licensed as a betting intermediary, the platform verifies the customer’s identity before the first deposit, the platform is a GAMSTOP member, and the customer who self-excludes through GAMSTOP is blocked at the platform for the duration of the exclusion. The platform is also bound by the LCCP, including the marketing rules and the customer-protection duties. A customer who chooses an unlicensed offshore product loses all of those protections, and the bet is placed with the operator’s own house rules.

The licensing frame in Great Britain

The Gambling Commission licenses the whole commercial market in Great Britain under the Gambling Act 2005. Since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based, and a Curaçao, Maltese or Gibraltar licence is not a substitute. Northern Ireland is outside the Act and has its own older law, so the language is “Great Britain licence” or “GB-licensed”, not a GB licence that regulates Northern Ireland. The Commission’s public register, searchable by business name, trading name, domain or account number, is the test of who holds a licence.

Betting exchanges run under a betting intermediary licence, which is the licence category the register reads “remote betting intermediary”. The ten operators reviewed on this page hold one of two licence categories. Three — Betfair, Smarkets and Matchbook — are licensed as remote betting intermediaries and can run a back-and-lay marketplace. Seven — Kalooki Sportsbook, BetTom, DAZN Bet, Midnite, Star Sports, Fafabet, Bet600 — are licensed as remote general betting standard (real events) and run fixed-odds sportsbooks, with varying amounts of in-house exchange-style product. The register’s category is the audit; a brand whose card says “remote general betting standard” is not licensed to run an exchange, and a brand whose card says “remote betting intermediary” is licensed to do exactly that.

The customer verification is the price of admission. Name, address and date of birth are verified before a customer can deposit or gamble at a licensed site, in force since 7 May 2019, including with a free bet or a bonus. A credit card is banned for gambling in Great Britain since 14 April 2020, including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered by the ban. There is no anonymous play at a licensed site, and a customer who wants to bet without giving a name is looking at an offshore brand, not a Commission-licensed one.

The minimum age is 18. The Commission has, since 30 August 2024, applied a financial vulnerability check (LCCP condition 3.4.4) to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, in force since 28 February 2025. The check is a public-record check, looking for things like bankruptcy or county court judgments, not an income check and not a credit reference check. Financial risk assessments, the press’s “affordability checks”, are announced in a staged plan from a Commission article of 7 July 2026, with no start date. A bettor who wants to know which checks apply reads the operator’s own page; the rules above are the licence conditions, the operator’s own page is how they are applied.

Safer gambling, GAMSTOP and where the bettor finds help

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Every GB-licensed online operator, including the ten reviewed here, takes part. A customer who registers with GAMSTOP chooses a period: six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The exclusion covers online sites and apps; betting shops use a separate service. A customer who has self-excluded and is still able to log in at a licensed site is on a product that is breaking the LCCP, and the right response is to contact the operator and GAMSTOP.

A deposit limit is the customer’s own tool, and the operator must offer a gross deposit limit on a fixed time frame under RTS 12. The first changes applied on 31 October 2025, a second phase was postponed to 30 September 2026, and whether the second phase is live is not established in a way the page can lean on. There is no state-set deposit or loss ceiling for betting: limits are the customer’s choice, and the licensed operator offers the tools to set and enforce them. A bettor who sets a limit at £200 a week at any of the ten operators on this page is setting a limit the operator is bound to honour, and the limit is one of the cheaper safer-gambling tools a bettor has.

Help is available outside the operator. GamCare runs the National Gambling Helpline; GambleAware is the Commission-preferred source of information on treatment and support; the NHS runs gambling clinics; Gamblers Anonymous runs peer-support meetings. The numbers and links are on the operator’s safer-gambling page, and the bettor who finds themselves betting more than they meant to, chasing losses, or hiding their betting from people they live with, is the bettor the services are designed for. The Commission does not endorse any single provider; the bettor picks the one they will actually use.

A bettor who wants to bet at an unlicensed offshore brand loses all of these protections. The unlicensed brand is not a GAMSTOP member, is not bound by the LCCP, is not bound by the 10x bonus cap, is not bound by the £150 vulnerability check, and the bettor has no British consumer redress if the operator withholds funds. The enforcement against unlicensed operators is disruption, not blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and court-order DNS blocking powers that the Commission has been given or is about to receive. The bettor is not the target of the enforcement; the bettor is the one who loses the protection.

The full operator reviews

Betfair — the deepest liquidity and the most products in one app

Betfair runs two products: the exchange, which is the original back-and-lay marketplace, and the sportsbook, which is the fixed-odds product the group has run since the merger with Flutter in 2001. The two sit on the same account but the bettor sees them as separate products, with separate apps, separate bet slips and a separate set of prices. The exchange is the licensed betting intermediary, with the licence category on the Commission’s register reading “remote betting intermediary” for the group and the sportsbook operating under the group’s remote general betting standard (real events) licence, account 39439. The bettor who uses the exchange is using the product the brand was built around; the bettor who uses the sportsbook is using a product the group has built out over the last decade.

The headline products are on the sportsbook side: in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football within the app, and a 90 Minute Payout market. The 90 Minute Payout market is a football-specific product: a bet on the match result settles at the 90-minute score, regardless of extra time or penalties, and a customer who has backed a team that is ahead at the 90 but loses in extra time is paid as a winner. The free live streaming is one of the better-known product offers in the British market, and a bettor with a funded account or a qualifying bet can watch a wide range of UK and Irish racing and football from the app. The exchange is the more interesting product for a bettor who wants to take a price and offset it; the sportsbook is the more interesting product for a bettor who wants a single click and a fixed price.

The commission on the exchange is published in the account settings and varies by customer, market and trading volume; a high-volume customer can negotiate a rate below 2%, a low-volume customer pays the standard rate. The 90 Minute Payout market is a sportsbook product with a sportsbook margin, and the bettor who wants to know the margin does the arithmetic on the price they are taking. The bettor who wants to use the brand for both products is using the strongest exchange and the strongest sportsbook in the British market; the bettor who only wants the exchange can also consider Smarkets and Matchbook, and the comparison between the three is on price, commission, market depth and the polish of the app.

Smarkets — the cleanest commission structure and a 0% offer for new customers

Smarkets is a betting exchange and only a betting exchange. The brand runs no sportsbook product, no casino, no bingo, and the bettor’s only path to a price on a sporting event is the back-and-lay marketplace. The simplicity is the product. The platform’s Commission licence is a remote betting intermediary licence, account 39173, and the licence holder is Smarkets (Malta) Limited. The platform verifies a customer’s identity before the first deposit, is a GAMSTOP member, and the customer who self-excludes is blocked at the platform for the duration of the exclusion.

The headline figure is the commission: 2% standard on eligible exchange bets, with 0% for 60 days for new customers who make a minimum first deposit of £10. The 60-day window is the cheapest period in the British exchange market for a new customer, and a bettor whose edge is on smaller markets where the bookmaker’s margin is wide is the bettor the 0% period is aimed at. The 0% period is paid in lower fees rather than higher free bets, and the saving compounds across the 60 days. The bettor who keeps betting after the 60 days is back to the 2% standard rate, which is at the lower end of the British exchange market and is published clearly in the account settings.

The market depth is the second comparison point. Smarkets has spent the last decade building liquidity in football, horse racing and a small set of US sports, and a customer who takes a price on a Premier League football match is taking a price in a market with more than one layer at the most common prices. The depth on smaller markets is thinner, and a bettor who lays a lower-division tennis match at 1.80 may find the matched bet sitting unmatched for a few seconds while the price finds a backer. The app is published as Smarkets: Prediction Markets, is rated 17+ in the British App Store, and carries the verification flow on the device. A bettor who wants the cheapest commission and the cleanest app is on the right platform; a bettor who wants a sportsbook on the same account is not.

Matchbook — the third exchange with a sportsbook bolted on

Matchbook runs a betting exchange and a sportsbook product, both licensed through the same Commission licence, account 39504, which carries both the remote general betting standard (real events) and the remote betting intermediary categories. The bettor can back and lay on the exchange, take a fixed-odds price on the sportsbook, build a Bet Builder, place a multiple, bet in-play and watch live streaming of horse racing and greyhounds. The product range is the widest of the three licensed exchanges, and the bettor who wants both products under one account has a clean choice.

The commission on the exchange is published in the account settings and is competitive with Smarkets and Betfair; a high-volume customer can negotiate a rate below the standard. The sportsbook product carries a margin inside the price, and a bettor who wants to know the margin does the arithmetic on the price they are taking. The live streaming of horse racing and greyhounds is a product the bettor who bets on racing will use; the bettor who bets only on football will use the in-play product more than the streaming. The app is published as Matchbook Betting Exchange, is rated 17+ in the British App Store, and carries the verification flow on the device.

The choice between Matchbook and Smarkets is on commission, market depth and the bolted-on sportsbook. The bettor who wants the cheapest exchange-only product is on Smarkets; the bettor who wants a sportsbook on the same account is on Matchbook or Betfair. The bettor who wants the deepest liquidity on football and horse racing is on Betfair; the bettor who wants a clean commission structure with a 60-day 0% offer is on Smarkets; the bettor who wants both products under one account and a slightly smaller commission is on Matchbook. The three are not interchangeable, and the comparison is the bettor’s call.

Kalooki Sportsbook — a new licence on a small platform

Kalooki Sportsbook is operated by Kalooki Sports Book Ltd, a UK-registered company with company number 12938274. Its remote general betting standard (real events) licence, 57730, is held by Kalooki Sportsbook Limited, and the platform is a GAMSTOP member. The brand is one of the newer licences on the British market, and the platform’s product range is correspondingly narrower than the longer-established names.

The platform is a fixed-odds sportsbook and not an exchange. The bettor’s path to a price is the operator’s price, the margin is inside the price, and there is no back-and-lay marketplace. The brand does not advertise a headline product in the way the longer-established names do, and the bettor who chooses the platform is choosing a small licensed bookmaker with the protections the licence carries. The bettor who wants a betting exchange is not on this platform.

The right reader for Kalooki Sportsbook is a bettor who wants a Commission-licensed product, has read the operator’s own page, and is happy with the market coverage the platform offers. Customers looking for the deepest liquidity, the most in-play markets and the most product features use Betfair, Smarkets or Matchbook; the bettor who prefers a smaller licensed bookmaker finds it here or at other similar brands in the set. The honest framing is that a smaller bookmaker carries the same licence and the same protections as a larger one, and the bettor’s choice depends on product preferences rather than safety.

BetTom — a 50% welcome offer with a casino tail

BetTom’s headline product is the sports welcome offer: 50% back as a free bet of up to £50, with a matching 50% back up to £50 as free slot funds for casino play, with full terms. The operator holds a remote general betting standard (real events) licence, 64959, held by Bet Tom Limited. The platform is a fixed-odds sportsbook with a casino product bolted on, and the welcome offer covers both.

The 50% back as a free bet is a sportsbook offer: a new customer places a first bet, and if the bet loses, 50% of the stake, up to £50, is returned as a free bet. The free bet is a sportsbook free bet, the stake is not returned with a win, and the free bet is subject to a wagering requirement that is capped at 10x under the LCCP since 19 January 2026. The matching 50% back up to £50 as free slot funds is a casino offer on the same platform, and the small print is where the value is. A bettor who reads the small print and is happy with the wagering and the time limit has a 50% offer that pays out at the 10x cap; a bettor who reads the small print and is not happy is better off on a different platform.

The mixed-product shape of the offer — one sign-up, one deposit, a sportsbook bonus and a casino bonus — is the kind of offer the Commission’s mixed-product ban is aimed at, and the bettor should check whether the offer is still on after 19 January 2026 in the form described. A bettor who is offered a sportsbook welcome and a casino welcome on the same product after that date is being offered something the LCCP says should not be on a licensed product, and the right response is to ask the operator. The page does not assert that the offer has been withdrawn, and the bettor who is reading this at the operator’s own page reads the current terms before opting in.

DAZN Bet — cash out, bet builder and the 90-minute rule

DAZN Bet’s headline products are Cash Out, Bet Builder, daily bet boosts and in-play betting, with the standard caveat that cash out availability is not guaranteed and bets stand if the cash out product is unavailable. The platform is licensed under account 48756 by the Gambling Commission for remote general betting (real events), held by DZBT Limited. The platform is a fixed-odds sportsbook and not an exchange.

The cash out is a one-click product: a bettor closes a position at a price the operator sets, and the operator bears the risk of the rest of the event. The cash out is not always available, and a bet whose position the bettor would have closed at half-time because the price was favourable stays open if the product is unavailable. The bet builder is a same-game multi on a single event, priced as a single product with an inbuilt operator margin. The daily bet boosts are short-term price enhancements on selected markets, often with a maximum stake and a maximum payout. The in-play product is a feed of in-play prices on selected events, where the operator takes its margin from the odds themselves.

The right reader for DAZN Bet is a bettor who wants a Commission-licensed sportsbook with cash out, bet builder and a stream of daily boosts, and is happy with the markets the platform offers. For a back-and-lay marketplace, Betfair, Smarkets or Matchbook are the standard choices; for a broader sportsbook product range, Betfair, Betway or other longer-established brands are suitable. The bettor who wants cash out specifically is on a product that has it; the bettor who wants the cleanest back-and-lay marketplace is on an exchange.

Midnite — a £5 qualifying bet and a £25 free bet for new customers

Midnite’s headline product is the sports welcome offer: a new customer who bets £5 or more on pre-match odds of EVS (2.0) or greater within 14 days of sign-up receives £25 in free bets and 50 free spins, valid for 7 days. The operator’s remote general betting standard (real events) licence, 101839, is held by Midnite Limited. The platform carries in-play events, an acca builder, popular accas and price boosts with maximum-stake limits.

The £5 qualifying bet is the smallest qualifying stake in the set, and the £25 free bet is one of the larger free bets for the qualifying stake. The minimum price is EVS (2.0), which is the standard “odds against” threshold in British usage, and the qualifying bet has to be on a pre-match market. The 14-day window from sign-up is the qualifying window, and the 7-day validity on the free bets is the spend window. The wagering requirement on the free bets is capped at 10x under the LCCP, and a bettor who reads the small print has a £25 free bet with a known wagering cost.

The acca builder, popular accas and price boosts are the headline sportsbook products. The acca builder is the bet builder product under a different name, and the popular accas are pre-built accumulators the platform has selected. The price boosts are short-term price enhancements on selected markets, with a maximum stake and a maximum payout. The in-play product is a feed of in-play prices on selected events. The bettor who wants a small qualifying bet, a clear free bet and a clean sportsbook product is on the right platform; the bettor who wants an exchange is not.

Star Sports — boosts and in-play on a smaller sportsbook

Star Sports runs pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts, plus in-play betting on football, horse racing, golf and US sports. Licence holder Star Racing Limited operates under a remote general betting standard (real events) licence, 9177. The platform is one of the longer-established licensed bookmakers in the set, and the licence is one of the older account numbers on the Commission’s register.

The Bet Boosts, Daily Specials and Weekend Enhanced Boosts are the headline products: short-term price enhancements on selected markets, with maximum stakes and maximum payouts published in the bet slip. The in-play product is on football, horse racing, golf and US sports, which is a narrower in-play range than the longer-established sportsbooks, and a bettor who bets on tennis, basketball or the smaller leagues is on a different platform. The platform does not advertise a betting exchange product; the bettor’s path to a price is the operator’s price and the operator’s margin.

The right reader for Star Sports is a bettor who bets on the sports the platform covers, wants the boost products, and is happy with a smaller in-play range. For exchange betting, Betfair, Smarkets or Matchbook are the alternatives; for a sportsbook with a wider in-play range, Betfair, Betway or one of the longer-established names are options. The licence is one of the longer ones on the register, and the bettor who values that history has a reason to choose the platform.

Fafabet — Best Odds Guaranteed on UK and Irish racing from 9am

Fafabet’s headline product is Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days: if the starting price is bigger than the original price, the bigger odds are paid. Its remote general betting standard (real events) licence, 57385, is held by Taichi Tech Limited. The platform is a fixed-odds sportsbook and not an exchange.

Best Odds Guaranteed is a horse-racing product, and a bettor who bets on UK and Irish racing is the bettor the promotion is designed for. The 9am start is the time the BOG turns on, and a bet placed before 9am at an early price is paid at the bigger of the early price and the starting price if the starting price is bigger. The each-way coverage is the wider of the two readings: a BOG that covers each-way bets is paid on both the win leg and the place leg at the bigger price, and a BOG that covers only win bets is paid on the win leg only. The small print at Fafabet covers both legs, and a bettor who reads the small print has a clear BOG.

The wider sportsbook product is a fixed-odds book where the operator builds a margin into every price. Those who prefer betting exchanges look to Betfair, Smarkets or Matchbook; for sportsbooks offering strong horse-racing BOG, Fafabet or Bet600 are popular choices. The choice between the two BOG operators is on the rest of the product range, the welcome offer and the in-play product; the BOG itself is the same on each.

Bet600 — Best Odds Guaranteed on horse racing

Bet600’s headline product is Best Odds Guaranteed on horse racing: if the starting price is bigger than the early or show price taken, the bet is paid at the SP. The platform operates under remote general betting standard (real events) licence 44731, held by Tyche Tech Limited.

The BOG is the same product as at Fafabet: a bet placed at an early or show price is paid at the bigger of the two prices, and the bettor is hedged against the price drifting between the bet and the off. The BOG is a horse-racing product, and a bettor who bets on horse racing is the bettor the promotion is designed for. The wider sportsbook product is a fixed-odds book where the operator builds a margin into every price. Those who prefer betting exchanges look to Betfair, Smarkets or Matchbook; for sportsbooks offering strong horse-racing BOG, Bet600 or Fafabet are popular choices.

The choice between the two BOG operators is on the rest of the product range, the welcome offer and the in-play product. The bettor who bets on racing regularly and wants a clean BOG has a real choice; the bettor who bets on football or US sports is on a different platform. The licence is a remote general betting standard licence, and the platform is bound by the LCCP and is a GAMSTOP member, and the protections are the same as at the other licensed operators in the set.

Reading the odds and seeing the margin

A decimal price of 2.00 means a £10 stake returns £20 if the bet wins, a profit of £10. A decimal price of 1.50 means a £10 stake returns £15 if the bet wins, a profit of £5. The stake is always returned with a win, on a decimal-price sportsbook, and the return is the stake multiplied by the price. A combination bet multiplies the prices of the legs into one price, and the return is the stake multiplied by the combined price. The arithmetic is the same in every case, and the bettor who knows the rule can read any price on the page.

The bookmaker’s margin is the difference between 100% and the payout share of a market. The payout share is the sum of the implied probabilities of all outcomes, where the implied probability of an outcome at decimal odds d is 1 / d. On a two-way market with prices 1.90 and 1.90, the payout share is 1 / 1.90 + 1 / 1.90, which is 0.5263 + 0.5263, or 1.0526; wait, that is more than 1, which is the bookmaker’s overround. The bookmaker’s margin on a 1.90 / 1.90 market is the overround minus 1, or 5.26%, in the worked example, and the payout share is 1 / 1.0526, or about 95%. The same market at 1.85 / 1.95 has a higher margin; the same market at 1.95 / 1.95 has a lower margin. The tighter the prices, the lower the margin; the wider the prices, the higher the margin. The bookmaker’s margin is the cost the bettor pays, in expectation, on every unit bet on the market.

The illustrative two-way market at 1.90 / 1.90, fractional 9/10, is a worked example, not a quoted price. The margin on this market is in the band 4.5% to 5.5% depending on the rounding, with the standard rounding placing it at about 5%. A real market at a real moment carries whatever margin the operator’s prices imply, and the audit is the bettor’s own arithmetic. A bookmaker who prices every Premier League match at 1.90 / 1.90 is a bookmaker with a 5% margin on the match result market, and the bettor who wants to know the price of being at that bookmaker does the arithmetic on the price they are taking. The bettor who wants a cheaper market is on a different bookmaker, or on an exchange where the spread is set by competing customers rather than by a single bookmaker.

The exchange’s margin equivalent is commission. A 2% commission on a winning back bet of £100 at 3.00 returns £300, of which the customer keeps £294. The bookmaker equivalent on a 5% margin at 2.85 returns £285. The exchange is cheaper for the winning bettor by £9 in the worked example, and the difference is the commission the exchange keeps. The losing bettor pays £100 on both, the stake is gone in both cases, and the cost is the same. The exchange is the cheaper product for the bettor who is right more often than the margin implies, and the more expensive product for the bettor who is wrong. The choice between the two is the bettor’s edge, not the platform’s price.

What an unlicensed offshore brand costs the bettor

An unlicensed brand is one that does not hold a Gambling Commission remote licence. The brand’s licence, if any, is in another jurisdiction, and the brand’s products are not licensed for use in Great Britain. A bettor who opens an account at an unlicensed brand is doing so outside the British regulatory frame, and the protections of that frame — GAMSTOP coverage, the LCCP, the 10x bonus cap, the £150 vulnerability check, the British dispute-resolution route — do not apply. The bet is placed with the operator’s own house rules, the operator’s own KYC, and the operator’s own complaints process.

The enforcement against unlicensed operators is disruption, not blocking. The Commission issues cease-and-desist notices, works with search engines to remove unlicensed brands from results, works with registrars, hosts and payment providers to take the brand’s infrastructure down, and has been given or is about to receive court-order DNS blocking powers. The bettor is not the target of the enforcement; the bettor is the one who loses the protection. A bettor who has funds at an unlicensed brand and asks the Commission for help is told the Commission cannot help, because the brand is outside the licence.

The honest framing: a licensed brand is the only path to the British protections, including verification before the first bet, the bonus cap, the vulnerability check and the dispute-resolution route. An unlicensed brand is the only path to anonymous play, cryptocurrency deposits and a wider product range in some cases, at the cost of the protections. The bettor’s choice is on the trade, not on which is “safe” by default, and a bettor who chooses an unlicensed brand is choosing the trade knowingly.

Where the bettor can check a brand’s licence

The Commission’s public register is searchable by business name, trading name, domain or account number, and the search is the test of whether a brand holds a licence. The bettor who sees a brand advertised as “licensed by the Gambling Commission” checks the register: the licence account number on the brand’s page is the number to search, and the licence holder’s name is the name to look up. The match between the brand’s claim and the register’s entry is the audit, and a mismatch is a red flag.

The ten operators reviewed on this page all hold a Commission remote licence, and the account number on each card is the number to search. The bettor who wants to confirm before opening an account opens the register, types the account number, and checks the licence holder’s name against the brand’s claim. The register is the public document, the brand’s claim is the marketing, and the register wins. The bettor who cannot find the brand on the register does not bet at the brand, because the brand is not licensed for use in Great Britain.

A second, smaller point: the brand’s domain proves nothing. A licensed brand may use a .com or a .co.uk; an unlicensed brand may use either. The register is the test, not the address bar. A bettor who reads “.co.uk” and concludes the brand is licensed is reading a domain, not a licence.

Frequently asked questions

How does a betting exchange work?

A betting exchange is a marketplace where customers bet against each other on the outcome of a sporting event; the platform itself is not a party to the bet. A back bet wagers that an outcome will occur, and a lay bet wagers that it will not; the layer takes the role a bookmaker normally plays. The platform matches back and lay bets, and earns revenue from a commission on net winnings rather than from a margin on odds.

How does bet exchange work in practice?

In practice, a bettor opens an account, verifies their identity, deposits funds, and chooses an event and an outcome. The platform shows a back price (the highest price another customer is willing to back) and a lay price (the lowest price another customer is willing to lay), with a small spread between them. The bettor places a back or lay bet, and the bet is matched when another customer takes the other side at the same price; unmatched bets sit on the platform until matched or cancelled.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Gambling Commission’s public register, on the Commission’s website, is searchable by business name, trading name, domain or account number. The licence account number on the brand’s own page is the number to search, and the licence holder’s name is the name to look up. A match between the brand’s claim and the register’s entry is the audit, and a mismatch is a red flag.

How is the return on a bet worked out from the stake and the odds?

On a decimal-price sportsbook, the return is the stake multiplied by the decimal odds, and the profit is the return minus the stake. A £10 bet at 2.50 returns £25 if the bet wins, a profit of £15. On a combination bet, the odds of the legs multiply into one combined price, and the return is the stake multiplied by the combined price.

What is the bookmaker’s margin and how can it be seen in the odds?

The bookmaker’s margin is the difference between 100% and the payout share of a market, where the payout share is the sum of the implied probabilities of all outcomes (1 / decimal odds, summed). On a two-way market at 1.90 / 1.90, the implied probabilities are 0.5263 + 0.5263, or 1.0526, and the margin is the overround of 0.0526, or about 5%. The same arithmetic on any market gives the bookmaker’s margin on that market.
