A bookmaker promo code looks like a gift: a string of characters, an image of a betting slip and a number in pounds. The string is the smallest part of what is actually being sold. What changes the picture is what sits around it: a wagering multiple, a minimum price, an expiry, the rule on whether the stake comes back with a win, and, from 19 January 2026, a Commission-imposed ceiling that applies whether the marketing likes it or not.

This page reads the offers that licensed UK bookmakers publish on the first page of their app. It walks through the legal frame that now governs them, the responsible-gambling scaffolding that runs alongside, and ten operators a Great Britain customer can actually open an account with. The aim is not to encourage signing up. It is to make plain what a code does to the bankroll, and what it does not.

Currency stamp: this comparison is current as of 27 October 2026 and was checked against the Gambling Commission’s public register, the named operators’ own terms, and the Commission’s social responsibility code.

How a bookmaker promo code works in Great Britain

A “promo code” in the betting market is shorthand for two different things, and a reader who treats them as one loses money on the second one. The first is a sign-up offer: deposit, place a qualifying bet, receive free bets or bonus funds. The second is an ongoing promotion for existing customers: acca boosts, price boosts, money-back offers, loyalty tokens. The strings entered at the cashier are usually optional — most licensed bookmakers credit the welcome offer on a simple opt-in — and the real work is done by the offer’s terms.

A sign-up offer, in the form most UK bookmakers run it, follows a template. The customer deposits a minimum amount, places a first bet at or above a stated minimum price (the kind of thing written as “min odds 2.0 (1/1)” or “min odds 1/2”), and receives free bet tokens in return. The free bets are credited to a separate balance, cannot be cashed out as cash, and expire after a fixed number of days. A win on a free bet returns only the profit, not the stake. A losing qualifying bet, at some books, also returns a free bet — the so-called “no-deposit” or “lose-and-get” style — but the same no-cash-out, no-stake-returned rule applies.

What makes the difference, before anything else, is whether the free bet carries a wagering requirement. Most free bets issued as part of a welcome offer do not: you receive the free bet, you place it, you keep what you win. Bonus funds are different in substance. A bonus is added to the account as withdrawable cash that cannot be withdrawn until the customer has wagered a multiple of the bonus (sometimes the bonus plus deposit) on qualifying bets at or above a stated minimum price, inside a stated window. That mechanism is where most of the cost to the punter lives, and it is the mechanism the Commission now caps.

The 10x wagering cap and the mixed-product ban in force since 19 January 2026

Two Commission rules govern how UK bookmakers can structure bonuses and free bets since 19 January 2026. They are part of the wider package of social responsibility changes introduced to slow the conversion of bonus credit into compulsive play. They have changed the shape of what a bookmaker can offer, and they are the single most useful number a punter can carry into the small print.

The first rule is a cap. Wagering requirements on bonuses are limited to a maximum of ten times the bonus amount, or ten times the bonus plus deposit where the deposit is part of the base. A £10 bonus at a 50x multiple used to mean £500 of qualifying bets before any of the bonus could be withdrawn. Under the cap, no qualifying turnover on a £10 bonus can exceed £100. The cap applies to the requirement, not to the bonus: a £50 bonus at 10x is still £500 of qualifying bets, because £50 × 10 = £500. The cap bites hardest on small bonuses at high multiples — the typical high-street welcome offer of the previous decade — and it leaves room for the larger bonuses that the bigger online brands prefer to run.

The second rule is a ban on mixed-product promotions. An offer that ties two or more product types together — “bet £10 on football to receive £20 in casino spins”, “deposit to get a sports free bet and bingo bonus in one package” — is not allowed. The Commission’s view is that a customer who came in to bet on sport should not be steered into casino play to clear a sports bonus, and vice versa. What a bookmaker does within a single product type is governed by its own terms and the LCCP; what crosses product types is now off the table.

Whether the 10x cap applies to free bets that carry no wagering requirement is not settled in the published guidance. Free bets as a category are not defined as bonuses in the same way: they are typically single-use tokens whose stake is not returned. The marketing norm since the rule came in has been to issue free bets without a wagering requirement, so the question is academic for most welcome offers. If a free bet does carry a rollover — some bookmakers do offer them with one — the 10x cap applies to that rollover in the same way it applies to a cash bonus.

A short note on the word “risk-free”. A stake-not-returned free bet is not risk-free: the stake is lost on a losing selection. A “money-back” offer that returns the stake as a free bet on a loss is closer to risk-free than its rivals, but the refund is a token, not cash, and the winnings from that token carry the stake-not-returned rule. The marketing term and the offer behind it are rarely the same thing.

Minimum odds, expiry, and the small print that actually moves the number

Three terms decide what a welcome offer is worth in practice. The first is the minimum odds on the qualifying bet. A bookmaker that requires the qualifying bet at 2.0 (1/1) is asking the punter to pick a winner at even money or longer, on the first bet after deposit, in exchange for the free bets. A bookmaker that requires 1.5 (1/2) is asking for shorter odds — a heavier favourite, a smaller return for the same risk. The lower the minimum odds, the easier the qualification; the higher, the more the punter has to back a less certain outcome to clear the offer.

The second is the minimum odds on bets placed with the free bet itself, where the bookmaker sets one. A free bet usable only at 2.0 or longer means the punter cannot place it on a banker at 1.2; a free bet usable at 1.5 or longer is more flexible. Most UK welcome offers leave the free bet free of a minimum price, which is part of what makes the difference between a free bet and a bonus with wagering.

The third is expiry. A free bet issued for seven days is a different proposition from a free bet issued for thirty days. The shorter the expiry, the more the punter has to fit the bet into a fixture list; the longer, the more the punter can wait for value. Expiry windows on UK welcome offers are typically seven days, sometimes longer for the bonus-credit variants. The clock starts when the free bet is credited, not when the account is opened.

There are three other terms worth reading before claiming. The first is the payment-method rule: most welcome offers require a debit card or instant bank transfer for the deposit; an e-wallet deposit or a paysafecard deposit can disqualify the offer. The second is the one-per-customer rule: welcome offers are limited to one per household, address, payment method and sometimes device, and a second account from the same household is not a route to a second welcome bonus. The third is the stake-not-returned rule on free bets, which is the single most expensive term of the package in the long run and the one most customers forget.

The arithmetic of a bonus turnover, in plain numbers

Take a £40 bonus at a 10x wagering multiple, the kind of structure most UK bookmakers publish for sports welcome offers. The arithmetic is straightforward. Required turnover is the bonus amount multiplied by the wagering factor, so £40 × 10 = £400 of qualifying bets. If the punter places £10 bets at minimum price 2.00, that is forty bets; if the punter places £5 bets at the same minimum, that is eighty bets.

The market matters as much as the numbers. The expected cost of clearing a bonus is the required turnover multiplied by the margin of the market the punter wagers on. Football match odds at a typical UK bookmaker carry a margin in the region of 5 to 7 per cent, meaning the bookmaker keeps roughly six pence in every pound wagered across the three outcomes. The punter who wagers the £400 required turnover on match-result singles at that margin gives up an expected £24 over the clearing period — the price of turning the offer into cash. A punter who runs the same turnover on accas at a 12 to 15 per cent margin loses £48 to £60 for the same work. The market the punter chooses is the second-largest cost of the offer, after the stake-not-returned rule on free bets.

A useful framing: the marketing number is what the punter receives. The real price is the required turnover multiplied by the market margin, plus any time-value lost by being forced into short-odds bets to clear it. Where the offer is a free bet rather than a cash bonus, the arithmetic changes shape: the value of the free bet is its face value multiplied by the edge the punter can find, minus the margin of the market it is placed on, with the stake not returned on top of that. A £10 free bet placed at odds of 4.00 on a market priced to a 6 per cent margin is worth about £7.20 in expected profit — a £10 face value, a £30 return on a win, the stake subtracted, multiplied by the 94 per cent payout share.

The same arithmetic, the other way round, is the reason bookmakers prefer bonus structures with rollover over free-bet structures with no rollover. A £10 free bet at odds of 4.00 is a one-shot gamble at a known cost. A £40 bonus at 10x is forty bets at minimum price, with the punter exposed to the bookmaker’s margin across the entire clearing window. The £40 bonus looks bigger; the £10 free bet is often cheaper to convert. This is the trade-off the small print is built to obscure.

What the marketing word is really saying, in numbers

A few common phrases, translated into the arithmetic of the last section:

• “£40 in free bets when you bet £20” means the punter wagers £20 of their own money on a first bet at minimum odds 1/1 (2.0), receives £40 in free bet tokens, and keeps only the profit if the free bet wins. The £20 stake is gone on a loss, the £20 stake is gone on a win, the £40 is paid out as profit only on a win.
• “100% up to £50 betting bonus” means a bonus equal to the deposit, up to a £50 cap, with a turnover requirement (typically 10x the bonus, sometimes bonus plus deposit) at a stated minimum odds, inside a stated expiry. A punter who deposits £50 and clears the bonus at 10x on football match results at a 6 per cent margin gives up an expected £30 over the clearing window.
• “Bet £10 get £30” means the same shape as the £40 offer above, in different numbers. The trade-off is stake versus return, not generosity versus stinginess.
• “Risk-free bet” usually means the stake is returned as a free bet on a loss, not as cash. The marketing word is “risk-free” because no cash is lost; the offer behind it is a free bet whose stake is not returned with the winnings.
• “Best odds guaranteed” on horse racing means the bookmaker pays the larger of the price taken and the starting price, on selected meetings. It is not an offer in the welcome-offer sense; it is a long-running concession whose cost is built into the margin.
• “Acca insurance” means a refund of the stake as a free bet if one leg of an accumulator loses. The refund is a free bet, not cash, and usually has a cap on the refund and a minimum number of legs.

Responsible gambling: the controls that sit around a welcome offer

A bookmaker promo code is offered inside a wider player-protection framework, and the same offer at an unlicensed operator has none of it. The framework is built from several layers, and a punter who knows the shape of it is in a stronger position to push back when a term is unfair.

The first layer is identity verification. Since 7 May 2019, licensed operators must verify the customer’s name, address and date of birth before the first deposit or the first bet — including a free bet or a bonus. Anonymous play at a licensed site is not available, and the verification is the reason a sign-up offer requires a debit card or a bank transfer rather than an unverified e-wallet.

The second layer is GAMSTOP, the multi-operator online self-exclusion scheme that has been a mandatory licence condition for online operators since 31 March 2020. A customer who registers with GAMSTOP is excluded from all UK-licensed online gambling sites and apps for the chosen period — six months, one year, five years, or five years with auto-renewal — and the exclusion runs for another seven years after the minimum period unless the customer asks for it to be lifted. GAMSTOP is an online scheme; betting shops use a separate service.

The third layer is financial checks. A financial vulnerability check applies to remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30-day window; the check is a public-record search, not a credit reference check and not an income check. A heavier financial risk assessment — the “affordability check” of the press — has been announced in a staged plan with no start date; “announced, staged, no start date” is the right way to write that, not “in force”.

The fourth layer is deposit limits. Operators are required to offer a gross deposit limit on a fixed time frame; the first phase of changes has applied since 31 October 2025, and a second phase was postponed to 30 September 2026. There is no state-set ceiling on deposits or losses at betting: limits are the customer’s choice, within the controls the operator offers.

The fifth layer is the support network. GamCare runs the National Gambling Helpline. GambleAware funds treatment. NHS gambling clinics treat gambling harm in person. Gamblers Anonymous runs peer-led meetings. A punter who feels the offer pulling them past their usual budget has a route to help, and a punter who needs that route is the customer the offer is best designed for.

The two layers worth flagging on a welcome offer are identity verification (which is what blocks a second account from the same household) and GAMSTOP (which is what blocks a self-excluded customer from accepting a new offer). A punter who is not in GAMSTOP is the customer the welcome offer is built for; a punter who is in GAMSTOP will be stopped at the verification stage, and the offer will not be credited.

The legal frame: who licenses what in Great Britain

The Gambling Commission is the regulator of the commercial gambling market in Great Britain, set up under the Gambling Act 2005. It is a non-departmental public body sponsored by the Department for Culture, Media and Sport. The Commission licenses operators, not bets: a licence permits an operator to offer certain categories of betting (remote general betting standard for real events; remote general betting standard for virtual events; remote general betting limited; remote pool betting; remote betting intermediary for exchanges) under the Licence Conditions and Codes of Practice. There is no statutory list of what may be bet on; markets are governed by the licence category and the operator’s own house rules.

The framework that applies to remote betting comes from the Gambling (Licensing and Advertising) Act 2014, which requires an operator whose remote facilities are used in Great Britain to hold a Commission licence wherever the operator is based. A Curaçao, Malta or Gibraltar licence is not a substitute. The domain tests should still be read with care: licensed operators use both .com and .co.uk, so the domain alone proves nothing. The whole test is whether the operator appears on the Commission’s public register, which can be searched by business name, trading name, domain or account number.

The Commission’s public register is the first place to check before opening an account. Each operator listed below carries a Commission account number — a five-digit figure — that appears on the register against the licence holder’s name. Where the licence holder is a group company rather than the trading brand (for example BV Gaming Limited for BetVictor, LeoVegas Gaming PLC for BetUK, PPB Counterparty Services Limited for Paddy Power), the register is the place to confirm the link; a single licence can cover several brands.

Northern Ireland is outside the 2005 Act and has its own older law. A “Great Britain licence” or “GB-licensed” is the right framing; a GB licence does not regulate Northern Ireland, and a Northern Ireland licence does not extend to England, Scotland and Wales. None of the operators reviewed here is licensed for Northern Ireland, and the welcome offers described apply to GB customers.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission, and a financial-spread betting bookmaker (Spreadex, in the set below) holds two licences: a Commission licence for fixed-odds betting and an FCA authorisation for spread betting. The two licences carry different protections: a financial-spread bet can lose more than the deposit, because the loss is the difference between the spread price and the settlement price, multiplied by the stake per point.

What may be bet on, and what may not

There is no statutory list of permitted bets in Great Britain. The Commission licenses categories; the operator runs markets under its licence category and its own house rules. In-play betting is offered by every major UK bookmaker and is governed by the operator’s licence conditions and its customer-protection duties. Esports are treated like any other event. Virtual events are a separate licence category. Bets on politics, on television shows and on novelty markets (the next Prime Minister, the winner of a reality contest) are offered by some GB bookmakers and no statutory prohibition was found.

Betting exchanges — Smarkets, Betfair, Betdaq and a small number of others — run under a separate licence category, the remote betting intermediary licence. Exchange rates and rules are stated from each exchange’s own terms; the Commission’s role is to license the platform, not to set commission rates or minimum stakes. Spread betting on sport that is not a financial product is inside General Betting Duty and licensed under the general betting standard, not the financial-spread betting authorisation.

There is no statutory cap on stakes in sports betting. Operators set their own maximum stakes and may restrict a customer at any time, on grounds including winning pattern, payment-method history and verification status. The pattern matters: a winning punter at one bookmaker often finds the maximum stake on the next bet reduced, with no explanation given. The pattern is a commercial decision by the operator, not a regulatory one, and it is the reason sharp Pinners maintain accounts at more than one bookmaker.

Advertising, ASA, and the whistle-to-whistle code

Advertising is not licensed by the Commission. The CAP Code governs non-broadcast advertising; the BCAP Code governs broadcast. Both are enforced by the Advertising Standards Authority. The LCCP social responsibility code adds operator-side duties on top of the ASA rules. CAP Code section 16 is the relevant section for gambling: marketing must be socially responsible, must not be of strong appeal to under-18s, and no one who is or seems to be under 25 may feature gambling or play a significant role, with a narrow exception for marketing placed where a bet can be made directly. The rule is about who may appear in an advert, not who may bet.

Whistle-to-whistle is an industry code, not law: since 1 August 2019, betting advertisements are not shown on television in the five minutes before and the five minutes after a live sporting event, before the 9pm watershed, with horse and greyhound racing excluded. The Premier League’s voluntary withdrawal of gambling sponsorship from the front of matchday shirts from the 2026/27 season onwards is voluntary, not law; sleeves and stadium hoardings remain. The change is a commercial decision by the clubs, not a regulatory one.

Operators are responsible for marketing by their affiliates, which is the legal reason a “promo code” attached to an affiliate link carries the same terms as the bookmaker’s own offer. A code is not a separate deal; it is a way of attributing the sign-up to a particular affiliate, and the bookmaker’s terms apply. The Commission’s stance on affiliate marketing has tightened in the last decade, and a punter who clicks an affiliate link should still expect the offer described on the operator’s own page.

Tax: what the punter pays, and what the bookmaker pays

The player pays no tax on betting winnings in Great Britain. The treatment is general, not specific: a professional gambler, in HMRC’s view, is treated differently from a recreational punter, and a punter whose activity constitutes a trade should ask HMRC or an adviser. For the customer described in this page — a recreational punter using a sign-up offer at a licensed bookmaker — the winnings are paid out gross.

The bookmaker pays General Betting Duty, currently 15 per cent of gross profits on general betting. From 1 April 2027 a new remote betting rate of 25 per cent applies within that duty on remote bets other than those on UK horse racing, on self-service betting terminals in licensed premises, on pool betting and on in-person betting. Until 1 April 2027 the remote rate stays at 15 per cent. Whether operators pass duty on through the odds is not established; the marketing material does not say, and never write that the player is charged duty. The duty is a tax on the operator, not the customer.

Spread betting has its own rates: 3 per cent on financial spread betting, 10 per cent on other spread betting. The Commission’s statutory levy is a separate charge, not a tax. None of these is a charge on the punter’s stake or winnings.

Offshore and unlicensed: what is lost when the licence is missing

A GB licence is compulsory at the point of consumption. Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005, aimed at the operator. No offence aimed at a customer who merely bets on an unlicensed site was found; the legal exposure is the operator’s. What is lost for the customer is the protection framework, not a criminal record.

The loss runs across several layers. An unlicensed operator is not part of GAMSTOP, so a self-excluded customer can place a bet there. An unlicensed operator is not bound by the 10x bonus cap, so a £10 bonus at 50x is allowed; it is also not bound by the mixed-product ban, so a sports-casino bundle is allowed. An unlicensed operator does not run the £150 financial vulnerability check, so a customer spending more than £150 in 30 days is not checked against public records. An unlicensed operator does not contribute to the approved dispute-resolution bodies, which is the route a customer uses when a licensed operator withholds funds unfairly. And an unlicensed operator is not covered by British consumer redress: a customer whose account is closed with funds inside has limited recourse.

The Commission’s enforcement is disruption, not blocking. Cease-and-desist notices, search-engine referrals, work with registrars and hosts, and payment-provider pressure are the published tools. Court-order DNS blocking powers have been given, or are about to be given, to the Commission; ISP blocking is not in operation as a permanent measure. A punter who wants to bet with an unlicensed operator is betting in a market without British consumer protection, and the framing that matters is the loss of protection, not the legal status of the bet.

The licensed side is not without its own costs. Identity verification before the first bet means no anonymous account. The £150 rolling-30-day check is intrusive at higher spend. The 10x cap is a Commission rule that limits what a bookmaker can offer. A punter who prizes privacy above all else finds the licensed side heavier than the offshore side, and a punter who has had a self-exclusion lapse finds the licensed side difficult to enter. Neither side is “the safe choice” by default; the licensed side is the side that trades some privacy and some flexibility for the British protection framework, and that is the trade-off this page is built around.

How to read the comparison table

The table below covers the ten operators featured on this page. The columns are the operator, the Gambling Commission remote licence number and licence holder, and a short summary of what the operator’s own terms say on the key subject: the welcome offer for new customers, where the operator runs one, with the qualifying stake, the minimum odds and the expiry. Where the operator does not publish a sports welcome offer, the key subject falls back to the most relevant promotional mechanism in its terms.

The licence number is the Commission’s account number on the public register; the licence holder is the company name that holds the licence (which may be a parent or group company rather than the trading brand). The licence holder is the legal party to the offer; the trading brand is the customer-facing name. The Commission register is searchable by account number, business name, trading name or domain, and is the whole test of whether a brand holds a licence.

The operator’s terms on the key subject are taken from the operator’s own website or its official App Store listing, current as of the snapshot at the top of this page. A punter who has opened an account in the last few weeks should check the operator’s own current terms, because welcome offers are revised more often than licence numbers are.

Operator write-ups

Each write-up below reads the operator’s offering on its own terms and against the framework set out above. None is a recommendation. The aim is to put the offer, the bonus structure, the player-protection layer and the trade-off on the page at the same time, so a punter can compare one operator against another without leaving the page.

Unibet

Unibet’s UK site runs on Platinum Gaming Limited’s remote general betting standard licence, account 45322, and has been operating since 1999. The welcome offer is the £40-in-free-bets-when-you-bet-£20 template: deposit and bet £20 or more at minimum odds 2.0 (1/1), receive £40 in free bets within seven days, with the tokens expiring seven days after issue and the deposit requiring a debit card or an instant bank transfer. The offer is for new GB customers only.

Beyond the welcome offer, Unibet runs Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting across most sports, Best Odds Guaranteed on UK and Irish horse racing, and Cash Out on thousands of markets. The combination is broad enough that a punter who joins for the welcome offer is unlikely to find the platform empty within a fortnight.

The trade-off is the welcome offer itself. £40 in free bets on a £20 qualifying bet is a reasonable face value, but the free-bet stake is not returned with a win, the seven-day expiry on the free bets is tight, and the minimum odds on the qualifying bet (2.0) rule out the easiest way to qualify. A punter who plans the qualifying bet around a fixture they would have bet on anyway is the customer this offer rewards; a punter who has to find a bet at 2.0 just to qualify is paying a real price for the £40.

Paddy Power

Paddy Power’s UK site runs on PPB Counterparty Services Limited’s remote general betting standard licence, account 39439, which also covers Betfair under the same group. The App Store listing does not pin a single headline welcome offer for GB customers in the snapshot; the operator’s promotional weight is on its existing-customer features instead.

Those features are where Paddy Power’s offering sits. Bet Builder+ combines markets from one event into a single bet. Popular Bet Builders are pre-built combinations of the most-backed selections. Super Sub rolls a bet over to the replacement player if a selected player is substituted mid-match, which is a real edge on football player markets. Win More markets are expanded win markets on selected events, and the player and ACCA stats pages support the betting rather than decorate it. A punter who plays the in-play markets heavily is the customer Paddy Power is built for.

The trade-off is the absence of a clear, headline welcome offer in the snapshot. A punter who joins Paddy Power for the welcome offer is joining a platform that runs its promotional weight on existing-customer features, and the welcome page is likely to be a moving target. The licence is the licence the Betfair exchange runs under as well, meaning Paddy Power’s promotional focus lies on its existing-customer features rather than a headline welcome offer.

Copybet

Copybet’s UK site runs on Copybet UK Limited’s remote general betting standard licence, account 53774. The App Store listing does not pin a single headline GB welcome offer either; the existing-customer mechanics are the published perks.

The Acca Booster pays up to a 100 per cent cash bonus on accas of at least three selections. The Daily Profit Boost is up to a 15 per cent boost on selected bets. The two are different mechanics: the Acca Booster is a bonus on the winnings of a winning acca, paid as cash; the Daily Profit Boost is an enhanced price on a selected market. A punter who backs accas is the customer the Acca Booster is built for, and a punter who backs singles is the customer the Daily Profit Boost is built for.

The trade-off is the same as Paddy Power’s: the welcome offer is not the published product. A punter who joins Copybet for the welcome offer should check the operator’s own current terms, because the App Store listing is a snapshot rather than a current terms page, and a moving target is hard to plan around. The licence is a fresh one (account 53774), and the current promotional strategy focuses on existing-customer perks rather than a fixed sign-up bonus.

London Bet

London Bet is published by Thistle Bet Limited, account 66162, and its app carries a 17+ App Store age rating. The published terms on the App Store listing do not pin a specific welcome-offer structure in the snapshot, and the operator’s licence is on the public register against the trading name London Bet.

The honest framing here is a thin one: a small operator with a single licence category, a UK presence, and limited published terms on the listing. The Commission register is the place to confirm the licence; the operator’s own terms page is the place to confirm the current welcome offer, if any. A punter who joins London Bet on the strength of an offer advertised through an affiliate link should check the offer on the operator’s own site before depositing, because affiliate pages sometimes run offers that have been superseded on the operator’s own site.

The trade-off is platform weight. A small operator can offer a sharper welcome offer than the bigger brands, because the marketing budget is lighter and the promotional spend is concentrated on the first deposit. It also offers less on the days after the welcome offer, because the daily price-boost list, the acca-insurance terms and the live-streaming roster are thinner than a bet365 or a Sky Bet. The licence is the licence; the product depth is the review.

Betway

Betway’s UK site runs on Betway Limited’s remote general betting standard licence, account 39372. The welcome offer is £40 in free bet tokens, credited as four £10 free bets on settlement of a first bet of at least £10 at minimum odds 2.0, with a 7-day expiry on each token and debit card deposits only. The structure is the same £40-in-free-bets-when-you-bet-£10 template as several of its rivals, with the minimum odds at 2.0 and the expiry tight.

Betway is one of the larger international operators in the set, with a casino and a sportsbook that share the brand. The sportsbook product covers the major UK and Irish horse racing meetings, Premier League and Champions League football, the major US sports, tennis, golf and a long tail of smaller markets. The casino product is a separate licence category and not part of the welcome-offer analysis here.

The trade-off is the welcome-offer expiry. Seven days on four £10 free bets is a tight window, and a punter who does not have a planned bet at minimum odds 2.0 inside seven days will leave value on the table. The minimum odds on the qualifying bet are higher than the 1.5 minimum some rivals set, which is the structural reason Betway’s free-bet face value is the same as its rivals’ even though the qualifying stake is half.

10bet

10bet’s UK site runs on Blue Star Planet Limited’s remote general betting standard licence, account 43173. The App Store listing advertises a 100 per cent up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins. The betting bonus is a bonus, not a free bet, and the small print will determine whether it is a 10x turnover bonus or a heavier structure. The Commission cap on wagering requirements is 10x; a bonus at 10x on £50 is £500 of qualifying bets, which is the upper end of what a UK sportsbook can ask under the cap. The free spins are a casino product and not part of this page’s analysis.

The trade-off is the bonus structure. A bonus that takes £500 of qualifying bets to clear is a different proposition from a free bet that is settled on one outcome. The cap means 10bet cannot run the £10 at 50x offers that were common before January 2026; the offer structure inside the cap is what it is, and the punter has to decide whether the £50 face value is worth the £500 of qualifying bets.

BetVictor

BetVictor’s UK site runs on BV Gaming Limited’s remote general betting standard licence, account 39576, which also covers the Heart Bingo and other group brands under the same parent. The App Store listing does not pin a single headline GB welcome offer; the listing describes regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by customer terms.

BetVictor is one of the longer-established UK bookmakers, with a heritage in horse racing that survives in the depth of the racing product. The football product is full-length: match odds, both teams to score, correct score, accas, bet builders, and player markets. The casino is a separate licence category. The price-boost frequency is the published metric, and a punter who bets on football accumulators is the customer BetVictor’s existing-customer promos are built for.

The trade-off is the same as several of its peers: no headline welcome offer pinned in the listing, and a moving target on the operator’s own page. The licence number is in the table; the current offer is on BetVictor’s own terms page.

Hollywoodbets

Hollywoodbets’ UK site runs on Hollywoodbets International UK Limited’s remote general betting standard licence, account 53028. The sports welcome offer is a stake-back-as-free-bet on the first qualifying losing acca: deposit £10 or more by card, place a sports acca with stake £10+, three or more legs and combined odds of 4/1 or greater; if the acca loses, the stake is returned as a free bet of up to £30, settled within seven days of registration; one free bet per customer.

The structure is a “no-deposit” style in the sense that the offer is paid out on a loss, not on a win, which means the punter does not need to win the qualifying bet to receive the free bet. The free-bet stake is not returned on a win, the maximum free bet is £30 (not the full £10 stake at 4/1 combined odds), and the seven-day window on the qualifying bet is tight. A punter who would have placed the qualifying acca anyway is the customer this offer rewards; a punter who has to find a 4/1 acca just to qualify is paying a real price for the £30 cap.

Hollywoodbets is a South African heritage brand with a UK-facing product, and the operator’s promotional weight on horse racing and football accas reflects the heritage. A punter who plays accas is the customer Hollywoodbets is built for; a punter who plays singles or in-play markets will find the welcome offer misaligned with their usual bet.

BetUK

BetUK’s UK site runs on LeoVegas Gaming PLC’s remote general betting standard licence, account 39198, which is a Group plc licence shared with other LeoVegas brands. The sports welcome offer is four £10 free bets on a £10+ deposit and a sports bet within seven days of registering: two of the free bets are restricted to football accumulators of four or more selections, and two to multiples of two or more selections. The free bets are valid for seven days, with opt-in required.

The structure is unusual: the free bets are restricted by bet type, not just by market. A punter who plays football accas of four legs or longer will use two of the four tokens naturally; a punter who plays singles or in-play markets will have to learn a new bet type to use the tokens. The seven-day expiry is tight. The minimum deposit is low (£10), which is the structural reason the face value is four £10 tokens rather than a single £40 token.

BetUK is a LeoVegas Group brand, and the Group’s product depth comes from the parent. A punter who joins BetUK for the welcome offer is joining a platform that runs on the Group’s sportsbook product, and the platform is more complete than the licence alone would suggest. The trade-off is the bet-type restriction on the free bets, which is the structural reason the offer’s face value is split across four tokens rather than paid as a single bonus.

Sky Bet

Sky Bet’s UK site runs on SBG Sports Limited’s remote general betting standard licence, account 67370. The welcome offer is £30 in free bets (three £10 tokens) on a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The minimum stake of 5p is the smallest in the set, and the minimum odds of 1/1 is the standard. The £5 minimum deposit is the smallest in the set.

Sky Bet is one of the larger UK operators by customer base, with a strong football and horse racing product and a casino and a bingo product alongside. The Sky Betting and Gaming Group plc structure is the legal parent, with SBG Sports Limited as the licence-holder entity. A punter who plays Premier League football is the customer Sky Bet is built for; the Group’s media footprint (Sky Sports) is the structural advantage a publisher offers Sky Bet, and the in-play product is built around the Sky Sports schedule.

The trade-off is the size of the qualifying bet. A 5p qualifying bet at 1/1 is the easiest qualification in the set, and a punter who joins Sky Bet for the welcome offer can qualify with a bet that costs five pence. The £30 face value on three £10 tokens is at the lower end of the set, and the seven-day expiry on each token is the standard. A punter who wants the easiest qualification rather than the largest face value is the customer Sky Bet’s welcome offer is built for.

What a welcome offer is really worth, in arithmetic

A punter who claims a £40 free-bet welcome offer at minimum odds 2.0 and places the free bet on a market with a 6 per cent margin faces an expected value calculation. The free bet pays out the profit only. A free bet placed at odds of 4.0 on a market with a 6 per cent margin returns, on a win, £40 × (4.0 − 1) = £120 of profit, with the £40 stake lost. The probability of the win is the implied probability of 4.0, adjusted for the margin: implied probability of 4.0 is 1/4.0 = 25 per cent; on a market with a 6 per cent margin, the true probability is closer to 26.5 per cent, and the payout share is 94 per cent. Expected value is 26.5 per cent × £120 = £31.80. The £40 free bet has an expected value of £31.80 on a 4.0 shot at a 6 per cent margin.

The same free bet placed at odds of 2.0 returns £40 × (2.0 − 1) = £40 of profit, with a true probability of about 47 per cent at a 6 per cent margin. Expected value is 47 per cent × £40 = £18.80. The £40 free bet has an expected value of £18.80 on a 2.0 shot. The difference is the value of finding a higher price, and the difference is the cost of placing the free bet at minimum odds.

The same arithmetic, applied to a £40 cash bonus at 10x wagering: required turnover is £40 × 10 = £400 of qualifying bets at minimum price. If the punter places £10 bets at minimum price 2.0, that is 40 bets. The expected cost of clearing the bonus on football match-result singles at a 6 per cent margin is £400 × 6 per cent = £24. The punter receives a £40 bonus and gives up £24 in expected margin, for a net expected value of £16 — before any time-value adjustment for being forced into short-odds bets to clear it.

The two structures are not the same kind of offer. A £40 free bet at minimum odds 2.0 has an expected value of £18.80 at a 2.0 shot, £31.80 at a 4.0 shot, depending on how the punter uses it. A £40 bonus at 10x has an expected value of £16 if cleared at minimum price on football match-result singles at a 6 per cent margin. The marketing numbers look similar; the real prices look different. The punter who reads both numbers before claiming makes a different choice from the punter who reads only the headline.

Where the data stops, and what to check before betting

This page reads the welcome offers as published on the operator’s own site or its official App Store listing at the snapshot date at the top. Welcome offers are revised more often than licence numbers are, and a punter who has opened an account in the last few weeks should check the operator’s own current terms before claiming. The licence numbers are stable; the welcome offers are not.

The figures on market margins are stated qualitatively. UK bookmakers carry margins of 5 to 7 per cent on Premier League match-result singles, 4 to 6 per cent on the largest horse-racing meetings, 8 to 12 per cent on smaller football leagues, and 12 to 20 per cent on accas and special markets. The exact figure varies by event, by market and by operator, and a punter who holds the odds on the same event at three or four bookmakers is the punter who knows the margin in practice.

The player-protection figures are stated from the Commission’s published rules. GAMSTOP periods are six months, one year, five years, or five years with auto-renewal, with a further seven-year tail. The financial vulnerability check applies at £150 of deposits minus withdrawals in a rolling 30-day window. The bonus cap is 10x. The mixed-product ban applies to offers that cross product types. These are Commission rules, not operator rules, and they apply across the licensed set.

Practical checks before claiming a welcome offer

Five practical checks, in order:

1. Check the licence. The operator’s account number is on the Commission’s public register. A punter who cannot find the operator on the register should not deposit.
2. Check the minimum odds on the qualifying bet. A 2.0 minimum is the standard; a 1.5 minimum is easier. A punter who has to back a 2.0 shot to qualify should plan a fixture they would have bet on anyway.
3. Check the expiry on the free bets. Seven days is the standard; longer is better. A punter who cannot find a planned bet inside the expiry window is leaving value on the table.
4. Check the payment-method rule. Most welcome offers require a debit card or an instant bank transfer. A punter who deposits by Skrill or Neteller often finds the offer void.
5. Check the stake-not-returned rule. Free bets return the profit only. A £10 free bet at 4.0 returns £30 on a win, not £40. The marketing word “free bet” obscures this; the small print does not.

What to do when the offer has been claimed

The offer is claimed; the qualifying bet is settled; the free bets are in the account. What next?

The free bets are settled on the first bet placed at the eligible price, and the stake is not returned. A punter who places the free bet on the highest-price eligible selection makes the most of the offer; a punter who places it on the first eligible market wastes the offer. The expiry is short (seven days at most of the operators above), and a punter who waits for the best-fitting fixture is the punter who gets the most out of the offer.

A punter who has cleared a bonus with a 10x turnover requirement should check the small print on minimum odds, eligible markets and expiry on the wagering itself. The same market-margin arithmetic applies to the wagering as to the free bet, and a punter who runs the wagering on Premier League match-result singles is paying a lower margin than a punter who runs it on smaller leagues or on accas.

A punter who does not want to clear a bonus can sometimes forfeit the bonus and withdraw the deposit. Most operators allow this; the small print on “withdrawal before completion” is the relevant section. A punter who accepts a bonus is committed to the wagering, and a punter who decides the wagering is too heavy should withdraw the deposit before placing a qualifying bet.

Frequently asked questions

How do you use a promo code at a UK betting site?

Most licensed UK bookmakers do not require a promo code at the cashier. A welcome offer is usually credited on a simple opt-in: register, deposit via debit card or instant bank transfer, place the qualifying bet, receive the free bets. Where a code does exist, it is entered at the cashier or at the registration stage and is case-sensitive. A code that does not work should be checked against the operator’s own terms page rather than the affiliate page that advertised it, because affiliate offers are sometimes superseded on the operator’s own site. The code is a tracking mechanism, not a discount; the terms are the offer.

What is the maximum wagering requirement on a betting bonus in Great Britain?

The Gambling Commission has capped wagering requirements on bonuses at 10x since 19 January 2026. A £10 bonus can require at most £100 of qualifying bets before any of the bonus can be withdrawn; a £50 bonus at the same cap requires £500 of qualifying bets. The cap applies to the wagering requirement itself, not to the size of the bonus. Where the bonus base is the bonus plus deposit, the cap applies to that combined figure. Free bets that carry no wagering condition are not covered by the cap in the same way, because they have no wagering condition to cap.

What do “minimum odds” and “wagering requirement” mean in a sign-up offer?

A minimum odds clause is the lowest price at which a bet counts toward the offer. A qualifying bet at minimum odds 2.0 (1/1) must be placed at even money or longer; a bet at 1.5 (1/2) is shorter and would not count. A wagering requirement is the multiple of the bonus that must be turned over in qualifying bets before the bonus can be withdrawn. A £20 bonus at 5x wagering requires £100 of qualifying bets at minimum odds 2.0 or longer before the £20 (and any winnings on it) becomes withdrawable. The two clauses work together: a low minimum odds makes the qualification easier; a high wagering requirement makes the clearing longer.

Why is the stake of a free bet not paid back with the winnings?

A free bet is a token whose stake is funded by the bookmaker, not by the punter. On a win, the bookmaker returns the profit on the bet only, because returning the stake would mean the bookmaker is paying out the punter’s stake as well as its own. A £10 free bet at odds 4.00 pays £30 of profit on a win, not £40 of return. The marketing word “free bet” obscures this; the offer behind it is a one-shot profit-only token. The trade-off is that the punter’s own bankroll is not at risk on the free bet itself, only on the qualifying bet that earned it.

Can a sports welcome offer be tied to a casino bonus under the new Commission rules?

No. The Commission’s mixed-product promotion rules, in force since 19 January 2026, ban offers that require gambling on two or more product types. A sports welcome offer that credits casino spins as part of the package is not allowed; a casino welcome offer that credits a sports free bet is not allowed. What a bookmaker offers within a single product type is governed by its own rules and the LCCP; what crosses product types is off the table. The ban applies to the offer structure, not to the operator’s product range: a bookmaker can still run a sportsbook and a casino, but it cannot tie the welcome offers together.

How can a punter check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is the whole test of whether a brand holds a licence. It is searchable by business name, trading name, domain or account number, and lists every licensed operator with the licence categories the operator holds. A five-digit account number (for example 45322 for Unibet, 39439 for Paddy Power, 39198 for BetUK) is the Commission’s identifier for the licence holder; the trading brand appears as a trading name against the licence holder. A brand that cannot be found on the register is not licensed, and a punter who cannot find it should not deposit.
