A price boost is a marketing line, not a free thing. The headline number is the odds the bookmaker wants the customer to remember; the cost is the wagering requirement attached to any bonus that comes with it, the minimum odds a qualifying bet must clear, the expiry on the free bet that follows, and the margin sitting inside the boosted market itself. From 19 January 2026 the Gambling Commission capped wagering requirements on bonuses at 10x and banned mixed-product promotions, so a bookmaker that once asked for thirty times the bonus in turnover can no longer do so. That single rule reshapes what a “best odds” tagline is worth in pound terms; this page walks through the ten UK-licensed brands running price boosts, what each one’s terms actually cost, and where the marketing gives way to the maths.

What “price boost” means, and what it costs

A price boost is a one-off enhancement to the odds offered on a market — usually a goalscorer, a match result or a specific player stat the trading team wants to push. The bookmaker raises its declared price for a short window, often a day, sometimes an hour. Some brands apply them as daily recurring offers on selected matches; others fire them on request via in-app notifications; a handful run an automated surprise “supercharge” where the price can jump several tiers at random, from a 2/1 shot to a 20/1 shot on a single bet. The wager behind the boost depends on three figures the brand states: the maximum stake the promotion accepts, whether the stake is paid back with the winnings, and any cap on returns from the boosted leg.

The advertised price is the part the marketing emphasises. The marginal cost is the margin the bookmaker builds into the underlying market anyway — typically between 5% and 8% on mainstream football match odds — plus the small print on max stake, on whether a free bet triggered by the boost expires in seven days or thirty, and on whether any return from the boost itself is paid in cash or as a free bet. The punter who reads only the headline sees the offer. The punter who reads the slip sees the cost.

A separate family of offers sits beside the price boost and shares most of its mechanics: bet credits, free bets, acca boosts, acca insurance, profit boosts and “best odds guaranteed” promises on horse racing. They are not the same thing as a price boost, but in the bonus terms that govern them they share the same wagering requirement, minimum odds and expiry. The Commission’s 10x rule, in force since 19 January 2026, sits over all of them.

The 10x wagering cap and what it changed

From 19 January 2026, the Commission’s social responsibility code limits bonus wagering to a factor of 10 on what the customer receives. A £10 bonus at a factor of 50 means the operator used to ask the customer to turn over £500 in qualifying bets before any winnings could be withdrawn; under the cap, no operator may demand more than £100 of qualifying bets to clear the same £10. The rule also closed a specific marketing trick. Mixed-product promotions — an offer that asks the customer to gamble on two or more product types such as betting and casino, for example “bet on football and get free spins” — are no longer permitted to anyone licensed for remote play in Great Britain.

The cap applies to bonuses. A free bet with no wagering condition sits in a grey zone the regulator has not closed; whether the 10x ceiling reaches it depends on how the operator frames the wagering. What the cap plainly does is take the worst offenders off the market. A bookmaker that advertised fifty times wagering in 2024 cannot do so today, and any number above ten on a current bonus page is a sign to walk away before entering card details.

The Commission framed the rule as a consumer-protection measure; it sits in the same LCCP social responsibility code that brought in mandatory deposit limits and the financial vulnerability check on deposits over £150 in a rolling 30 days. The same architecture governs safer-gambling tools such as GAMSTOP self-exclusion and the deposit-limit defaults operators must offer. Together they make the licensed British market a stricter environment for operators than it was two years ago, and they make the marketing trick harder to hide behind a list of bullet points.

Bonuses and free bets: how the structure works

A sign-up offer at a UK bookmaker is rarely a single number. Coral’s headline is “£40 in Free Bets when you bet £20”, but the small print says the £20 qualifying bet must be at minimum odds of 2.0 (1/1), the £40 in free bets is credited within seven days and expires seven days after it is issued, and only debit cards or instant bank transfer count as the funding method. Unibet runs the same headline with the same minimum odds and the same seven-day expiry, gated to the same two funding methods. Hollywoodbets bets in a different shape: new players who deposit £10 or more by card get their stake back as a free bet of up to £30 on a first losing accumulator (stake £10 or more, three or more legs, odds of 4/1 or greater, settled within seven days), one free bet per customer. BoyleSports gives £20 in free bets against a £10 qualifying bet, with a separate Irish variant in euros. Sky Bet splits a £30 free-bet credit across three £10 tokens, triggered by a first single or each-way bet of at least 5p at odds of 1/1 or greater. Betboro matches a first qualifying wager up to £25 as a free bet, requiring a debit-card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher.

Two patterns recur. First, the qualifying bet is a real-money bet at the operator’s published minimum price, so the customer effectively pays for the free bet by risking £10 or £20 in cash at near-evens. Second, the free-bet stake is rarely paid back with winnings. A £10 free bet at evens returns £10 in profit, not £20 in profit; this is the part the marketing never quite says and the part a careful reader watches for.

The minimum odds attached to the qualifying bet are also the floor for what counts toward any wagering factor if the bonus carries one. With the 10x cap in force that floor matters less than it did, but on a free bet with a wagering factor the floor still determines whether a placed bet counts.

A third pattern governs offers Spreadex and Spreadex alone runs: a £60 free-bet bundle for a £10 fixed-odds qualifying bet at minimum odds of 1/2, with the credit usable across both fixed-odds and spread betting. Spreadex is a hybrid broker: spread bets are regulated by the Financial Conduct Authority, fixed-odds bets by the Commission, and the same promotional envelope covers both sides of the firm. The qualifying window is also longer than most — 28 days from account opening rather than seven.

The arithmetic, using a worked example:

• Bonus amount: £20 free bet (Coral shape, scaled)
• Wagering factor: under the post-19 January 2026 cap, no more than 10x the bonus — a ceiling of £200 of qualifying bets on a £20 free bet
• Minimum odds on a qualifying bet: 2.0 (1/1)
• Expiry on the bonus: 7 days from issue

At a typical football match margin of 6%, and a typical stake of £10 placed at minimum odds of 2.0 to clear the bonus, the customer turns over £200 across twenty qualifying bets of £10 each. Each bet carries roughly £0.60 of margin to the operator, so the clearing cost sits around £12, against a free bet worth on average the cash equivalent of roughly £9.50 to £10.50 once the non-returning stake and the market margin are netted out. The bonus does not pay the customer; it pays them only when the cleared value exceeds the turnover cost.

That result comes as a band, not a single figure, because the margin varies by market and the qualifying bet price ranges across the bookmaker’s terms. The conclusion holds across both ends of the band: this free bet costs the customer something between a small loss and a small gain on average, depending on which markets they bet on.

Ten UK bookmakers running price boosts, ranked by what they actually offer

The ten brands below hold a Gambling Commission remote licence. Each one appears in the order research sets. Each comes with what sets it apart on a price-boost and free-bet comparison: a minimum-price rule, a tier of recurring boosts, a payout cap, or a funding gate that some readers cannot meet. The licensed set is wide; an exclusivity claim for any single brand is wrong.

Matchbook

Matchbook is a betting exchange, not a sportsbook, which is the line that defines its offer set. New customers get 110 days of commission-free betting from registration when they use the code shown in the app listing, after which the platform’s standard commission applies. A betting exchange lets the customer back or lay outcomes against other customers; the platform takes a slice of net winnings, not a margin on the odds. That commission is where the cost lives. On a price boost shaped as an enhanced price the cost is the same as any other bet — the commission on winnings. On an exchange price boost the headline odds tend to be sharper than a bookmaker’s, because the exchange itself is competing on price rather than on margin.

The 110-day commission-free window is the headline: it changes the price-to-cost ratio for the first three and a half months. Anyone weighing Matchbook against a fixed-odds sportsbook should do the maths on commission versus margin over the same period. The exchange only suits readers who already understand back-and-lay mechanics. For a reader who does not, the licence and the welcome window do not turn the interface into a sportsbook.

Coral

Coral’s welcome offer is the £40-free-bet-for-£20 shape, and the brand layers three other recurring offers on top of it: a daily free Reward Shaker, an Odds Booster on hundreds of markets, and a small stable of free-to-play games including Football Super Series with a £10,000 jackpot. The welcome offer is gated to a debit card or instant bank transfer; Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly all appear as accepted payment options, but the welcome tranche itself accepts only the first two.

The Odds Booster is the price-boost rail proper. Coral promotes boosted odds across hundreds of markets daily — the volume is the point, not a single marquee enhancement. The Reward Shaker is a separate daily free-to-play mechanism: the customer shakes a virtual device for small free-bet prizes rather than receiving a fixed credit. For a reader who wants a daily price-boost habit rather than a single-shot enhanced offer, that volume matters. Coral and Ladbrokes operate under one licence, so the comparison should not be read as a choice between two fully independent groups; the licence number on the Commission register is one, the house rules are largely the same, and the marketing differs.

NetBet

NetBet’s edge sits in its product mix rather than in any single headline price: Daily Boosts and Profit Boosts run alongside a free-bet offer, a Bet Builder with instant dynamic odds, and a sports-stats hub for the major leagues. The site markets itself as a small-stake enthusiast’s brand. The boost catalogue is wide; the bonus terms are ordinary. The reader comparing NetBet to the bigger high-street names will not see the same volume of pre-event markets, but the price-boost rhythm of daily plus profit is unusual outside the largest firms.

Unibet

Unibet runs the same welcome shape as Coral — £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 (1/1), expiry seven days from issue, debit card or instant bank transfer only. The brand has been live since 1999, runs out of Gibraltar under Platinum Gaming Limited, and holds Commission account 45322. On a per-offer comparison against Coral the two look interchangeable; the difference sits in the surrounding product: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play, Best Odds Guaranteed on horse racing and Cash Out across thousands of markets. For a reader who watches in-play football weekly, Uniboosts combined with the live stream is the more functional bundle; for a reader who bets on a single Saturday accumulator the welcome envelope is what matters and Coral matches it.

Betboro

Betboro is one of the smaller names in the comparison and runs a smaller welcome offer as a result: 100% matched free bet up to £25 against a debit-card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher. The three-selection qualifier at 1.60 minimum rules out singles or doubles as the qualifying wager, which is unusual — most welcome offers take a single bet as the qualifier, not an accumulator. For a reader who naturally bets accas on the first weekend, Betboro’s qualifier fits; for a reader who bets singles, the bonus will not unlock without a different staking plan.

London Bet

London Bet is run by Thistle Bet Limited and lists itself as UK-licensed with a 17+ App Store age rating. The site’s welcome offer sits in a smaller envelope than the high-street giants and the price-boost catalogue is narrower; the company’s role in a comparison is as a smaller brand running within the same regulatory perimeter. The reader who values a smaller bookmaker over a bigger one is the target. Anyone comparing welcome-offer sizes against Coral or Unibet will see London Bet come in lower.

10bet

10bet’s UK welcome offer is a 100% match up to £50 on a sports bonus, with daily free bets and free spins layered on top. The “up to £50” headline with a 100% match puts it ahead of the £25 ceiling at Betboro and behind the £40 fixed-deal at Coral and Unibet — the top of the comparison cluster sits at £50. The free-spins component pulls the offer into casino territory, and under the post-January 2026 mixed-product rule the operator cannot require a customer to gamble on the casino to claim the sports bonus; how 10bet handles that split in its terms is the operational detail that determines whether the headline actually pays out.

LiveScore Bet

LiveScore Bet’s edge is its payments set: debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. Apple Pay and Revolut Pay are not universal among UK bookmakers — many still run a debit-card-only welcome envelope. LiveScore Bet opening Apple Pay and Revolut Pay to the welcome offer is the differentiation; for an iPhone reader with a Revolut card that funding set changes which welcome offers they can actually trigger. The brand also carries the LiveScore heritage for in-play football coverage, and the bonus catalogue is mid-pack by size.

Kalooki Sportsbook

Kalooki Sportsbook is operated by Kalooki Sports Book Ltd (company number 12938274) and holds Gambling Commission account 57730. The brand markets four things: instant withdrawals by bank transfer within minutes, Best Odds Guaranteed on UK and Irish horse racing, in-play betting, and a daily-boost offer plus extra-place races. The instant-withdrawal claim is the practical differentiator for readers who care about how fast winnings reach a current account rather than how big the welcome offer is. The combination of BOG on horse racing plus extra-place races plus daily boosts is a horse-racing specialist’s package rather than a football specialist’s, which is where most of the comparison sits.

Hollywoodbets

Hollywoodbets’ sports welcome offer is a refund-style bet, not a fixed credit: new players who deposit £10 or more by card get their stake back as a free bet of up to £30 on their first qualifying losing accumulator (stake £10 or more, three or more legs, odds of 4/1 or greater, settled within seven days), one free bet per customer. The structure inverts the usual rule. Where Coral pays £40 in free bets upfront as long as the qualifying bet settles, Hollywoodbets waits for the qualifying accumulator to lose, then refunds up to £30 in free bets. For a customer who wins the first acca the offer yields nothing; for a customer who loses it, the refund is real and generous against the £10 deposit. It is the right offer for a small-stake football acca reader who knows their first bet is more likely to lose than to win.

How the smaller acca-boost rails stack up

Six of the brands in the comparison run separate acca-boost rails that sit alongside the price boosts proper. Each carries a small qualifier and a tier of return boosts:

• bet365: Bet Builder+ combining markets from one event into a single bet, available pre-match and in-play; Super Boosts; Winnings Boosts on Bet Builders and selected singles; daily Bet Boosts. The combination of in-play and pre-match Bet Builder+ is the practical differentiator — most rivals run a builder but lock it pre-match.
• William Hill: Football Acca Boost covers accas of two or more legs with each selection at 1/5 or bigger; boost from 3% on a double up to 200% on twenty or more legs; maximum boost of £10,000 per online bet; runs until 30 May 2027.
• BoyleSports: Acca Insurance with opt-in, £5 minimum stake, minimum odds of 1/2, maximum refund £20 as a free bet expiring in seven days; bets must be placed and settled on the same day. Acca Loyalty with opt-in, £5 minimum stake, combined minimum odds of 3/1, five or more settled legs, free bet expiring after seven days.
• Kwiff: Supercharge feature boosts the odds on a single bet instantly (for example from 2/1 to 20/1) and can apply to single or multi bets on any sport; Bet Builder and Bet Builder+ across games plus a guaranteed weekend acca boost.
• QuinnBet: free bets valid for seven days from credit, usable on any market at odds of 1/2 (1.5) or greater and maximum odds of 50/1; straight accumulators allowed, system bets such as Trixie, Patent and Yankee are not.
• Spreadex: Acca Boosts on football accumulators of three or more selections, cash boost from 5% on a treble up to 100% on a higher-leg acca.

Across the set the structural pattern holds: boost rails use small minimum stakes, low minimum odds, and seven-day expiries. The differences lie in the cap on returns, the sport coverage and whether the rail hits in-play as well as pre-match. For a Saturday football punter the cluster reads as one product under five names; for a horse racing reader who wants Best Odds Guaranteed the picture narrows immediately to Kalooki Sportsbook, Unibet and a smaller set.

The wagering arithmetic, in pounds

The worked figure uses these offer terms: bonus amount £20, wagering multiple 10x under the post-January 2026 cap, minimum odds 2.0, expiry seven days. At a typical £10 stake per qualifying bet against an average football 1X2 margin of 6%, the customer would need to place twenty qualifying bets to clear £200 of turnover, at a marginal cost to themselves through the embedded margin of around £12 in expectation. The £20 free bet itself is worth on average the cash equivalent of roughly £9.50 once the non-returning stake and the matched-bet pricing are taken into account, before counting the turnover cost. Netting the two figures against each other leaves the bonus between a small loss and a small gain on average, depending on which markets the customer bets on. The point of running the calculation is not to land on one figure; it is to show that the bonus is not free money either way, and that the post-19 January 2026 cap has narrowed the gap between offer and cost but has not closed it.

A second comparison point sits in the maximum bonus ceiling. The 10x cap means that on the largest welcome envelopes in the comparison — Coral and Unibet’s £40 free bet, Hollywoodbets’ £30 refund, 10bet’s £50 match — the underlying turnover ceiling is correspondingly larger in cash terms. A £40 free bet under a 10x ceiling still needs £400 of qualifying bets; a £50 match under the same factor needs £500. The harder ceiling is the expiry: seven days from issue turns £400 of qualifying bets into roughly £57 a day at £10-per-bet stakes, or twenty bets across the week. A punter who bets only at weekends will not clear the bonus in time.

Comparison table: licensing and bonus shape

Each licence number above is the entry on the Gambling Commission’s public register for that brand, where its trading name, account number, operating company and licence categories are all checkable directly. Two operators — Unibet and Coral — sit on different licences despite similar headline offers; the holding company at Coral is LC International Limited, while Unibet’s is Platinum Gaming Limited in Gibraltar. The Commission separates the two even where the welcome shape matches.

The regulatory frame behind every bonus

Great Britain regulation rests on the Gambling Act 2005 for England, Scotland and Wales; Northern Ireland sits outside the Act under its own older regime, which is why the writer and the marketing pages say “Great Britain” or “GB-licensed” rather than “UK-licensed”. Since the Gambling (Licensing and Advertising) Act 2014 any operator whose remote facilities are used in Great Britain needs a Commission licence wherever the operator itself is based; a Curaçao, Maltese or Gibraltar licence is not a substitute for the GB licence when the customer is in London, Manchester or Glasgow. There is no state monopoly on licences and no cap on the number that may be issued.

Identity verification has been mandatory at the point of first deposit since 7 May 2019; the credit-card gambling ban took effect on 14 April 2020 and closes credit-card-funded payments through an e-wallet as well as direct credit-card charges; GAMSTOP is a multi-operator self-exclusion scheme mandatory for every online operator since 31 March 2020; the financial vulnerability check applies to licensed remote betting when deposits minus withdrawals exceed £150 in any rolling 30 days, in force since 28 February 2025. None of these rules are optional, which is what the licensed-versus-unlicensed distinction comes down to: the licensed brand is the one to which they apply.

The promotion rules added a layer on top. From 19 January 2026 wagering requirements on bonuses are capped at 10x, and mixed-product promotions are banned. The Commission framed both changes as consumer protection, and the practical effect shows up in every bonus term above: the largest turnover ceiling any brand can ask for is ten times the bonus, and the operator cannot bundle a sports-bet bonus with a casino-spin sweetener under the same welcome envelope. A book that previously advertised thirty or fifty times turnover can no longer do so; a book that ran “bet on football to get free spins” no longer can.

Safer gambling and the licensed brand

The same code that governs bonus wagering also sets safer-gambling obligations. GAMSTOP periods are six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps only — betting shops use a separate service. Most of the brands above market the GAMSTOP link in their safer-gambling footer.

Deposit limits are not state-set. Operators must offer a gross deposit limit on a fixed time frame, but the customer sets the amount. The first changes to the deposit-limit standards have applied since 31 October 2025, with a second phase postponed to 30 September 2026; whether it is live is not established. The Commission’s safer-gambling framework does not impose a nationwide deposit ceiling; the only cap in force on deposits is the £150 monthly threshold that triggers a financial vulnerability check on the inflows.

Help outside the operator is provided by GamCare (which runs the National Gambling Helpline), GambleAware, NHS gambling clinics and Gamblers Anonymous. The ten brands above all link these; they are not alternatives to the operator’s safer-gambling tools but the next line of contact when an operator’s own tools are not enough.

Offshore: what the licensed brand gives that an unlicensed one does not

A Great Britain licence is compulsory at the point of consumption. Providing gambling facilities in Great Britain without the licence the Gambling Act requires is an offence under section 33 of the 2005 Act (on summary conviction up to 51 weeks’ imprisonment or a fine up to level 5 or both; six months in Scotland). The offence targets the operator; no offence aimed at a customer who merely bets on an unlicensed site has been found in the statute. The honest framing is not “legal” or “illegal”; it is about what protections the customer loses.

An unlicensed brand carries no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body and no British consumer redress if funds are withheld. The 10x bonus cap does not reach it, the £150 vulnerability check does not run, and identity verification is typically weaker. Honest framing: licensed = checks, limits, GAMSTOP, the bonus cap, plus verification before the first bet; unlicensed = none of those protections and possible loss of funds. Neither is “the safe choice” by default; the licensed brand is the one the rules apply to.

Enforcement against unlicensed operators is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers. The Commission has been given, or is about to receive, court-order DNS blocking powers; ISP blocking is not yet in operation, and it should not be claimed as such. The brand comparison on this page assumes the reader wants a brand to which the GB rules apply, not a workaround.

Tax on winnings

The player pays no tax on betting winnings in Great Britain; this is general information rather than tax advice, and a professional gambler should ask HMRC or an adviser. The operator’s tax is General Betting Duty, currently 15% on gross profits; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, self-service betting-terminal bets, pool betting and in-person betting stay at 15%. The duty is the operator’s liability. Whether any individual brand passes duty on through lower odds is not established and should not be claimed. Spread betting has its own rates (3% financial, 10% other).

How to verify a Gambling Commission licence in three checks

1. Search the Commission’s public register by business name, trading name, account number or domain. The register is the whole test of whether a brand holds a licence; a brand with no entry has no licence.
2. Check the licence categories. The standard GB sportsbook is “remote general betting standard (real events)”; a betting exchange is “remote betting intermediary”. A brand that holds only a casino licence cannot legally offer sports betting to a GB customer.
3. Verify the trading name against the site the customer is using. Licensed operators run on .com as well as .co.uk, so the domain proves nothing on its own; the trading name on the register must match the brand the marketing shows. LC International Limited is the corporate parent for both Coral and Ladbrokes, and Triplebet Limited holds the Matchbook licence; a reader who sees those names on the register should see the same brands in the marketing and not an unrelated site with a similar name.

Closing thoughts on which brand to choose

The brand-fit question on a price-boost page is unusual. The boost itself is comparable across brands: a daily enhanced price, an acca boost rail, a Bet Builder enhancement, a surprise Supercharge. The differentiation sits in the surrounding product — the in-play volume at bet365, the live-stream coverage at Unibet, the exchange mechanics at Matchbook, the BOG plus extra-place races at Kalooki Sportsbook, the Apple Pay and Revolut Pay funding at LiveScore Bet, the instant-withdrawal rail at Kalooki Sportsbook, the refund-shape welcome at Hollywoodbets. A punter who wants the highest headline free bet will end up at Coral or Unibet; a punter who already bets on racing will end up at Kalooki Sportsbook; an exchange reader will end up at Matchbook. The price boost itself is roughly the same product on each; the cost of clearing it sits inside the wagering cap, and the take-home sits inside the market margin.

Two warnings belong at the close. The marketing line is the brand’s optimism about its own offer; the calculation is the customer’s. A £40 free bet for a £20 qualifying bet looks generous until the wagering factor (capped at 10x) and the seven-day expiry are placed beside the minimum odds. A surprise Supercharge from 2/1 to 20/1 looks spectacular until the maximum stake is checked. Reading the price-boost page once and the terms page once takes ten minutes and is the difference between an offer that pays the operator and one that pays the customer.

Frequently asked questions

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

The Gambling Commission capped wagering requirements on bonuses at 10x from 19 January 2026. A £10 bonus at 50x used to require £500 of qualifying bets; under the cap, no operator may ask for more than £100 of qualifying bets to clear the same £10. The rule is one of two promotion reforms that took effect that month; the other is the ban on mixed-product promotions.

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

The minimum odds are the floor on the price a qualifying bet must reach to count toward the offer; Coral and Unibet’s terms require 2.0 (1/1), for example. The wagering requirement is the multiple of the bonus a customer must turn over in qualifying bets before any winnings can be withdrawn. The two figures interact: a bet placed below the minimum price will not count toward clearing the bonus, even at the right stake size. Always check both figures before placing the qualifying bet.

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

A free bet is credit, not cash; the bookmaker refunds the stake as winnings only when it returns profits to the customer, so the customer receives profit-only on the free bet. At evens a £10 free bet returns £10 in profit, not £20. This is the universal rule on UK bookmaker free bets unless the operator publishes a stake-included exception; none of the ten brands in this comparison publishes one.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

No. The Commission’s mixed-product promotion ban, in force since 19 January 2026, closes any offer that asks a customer to gamble on two or more product types — for example, betting plus casino — to claim the same welcome envelope. A sportsbook may still run a casino welcome bonus, but it cannot be conditioned on a sports bet. The 10bet welcome offer above is the kind of structure most affected; how the operator carves up the sports and casino elements in its terms is the operational detail that determines whether the headline actually pays out.

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

The Commission’s public register can be searched by business name, trading name, account number or domain. It is the whole test of whether a brand holds a licence. Cross-check the trading name on the register against the brand in the marketing, and confirm the licence category covers the product the customer wants to bet on. A standard GB sportsbook holds “remote general betting standard (real events)”; a betting exchange holds “remote betting intermediary”. A brand with no entry has no GB licence.

Are betting winnings taxed in Great Britain, and who pays General Betting Duty?

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits and is currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within the duty, while remote bets on UK horse racing, self-service betting-terminal bets, pool betting and in-person betting stay at 15%. This is general information, not tax advice; a professional gambler should ask HMRC or an adviser.
