Enhanced odds, price boosts, acca insurance — the marketing pages of British bookmakers lean on the same handful of words, and the offers behind them rarely behave the same way. A free bet that pays back its stake on a winning football selection is largely a different product from one that doesn’t. A bonus that needs fifty turns of the deposit is largely a different product from one that needs ten. And the Gambling Commission’s promotion rules, in force across Great Britain since 19 January 2026, changed the arithmetic of those offers without making any of the marketing louder.

This review looks at ten UK-licensed bookmakers through that lens. The headline price of each offer is what the marketing shouts. The terms beneath it are what the offer actually pays back, and what it asks the punter to risk before it pays. Where one bookmaker’s free bet comes as £40 in credits with seven days to use it, another’s splits into four £10 tokens tied to specific bet types. Those differences show up in the table that runs through this guide and in the operator-by-operator verdicts that follow.

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

Safer Gambling Comes First

A short section before the offers, because every discussion of enhanced odds in Great Britain rests on a frame the punter cannot see in the marketing. Enhanced odds are a marketing device for placing real bets, and the same protections that govern the bets govern the offers. They sit on top of the licence, not beside it, and they are the reason the rest of this page is a comparison of licensed operators rather than a round-up of whoever pays the most.

What the Commission requires of every licensed online bookmaker

Every bookmaker in this review operates under a remote licence issued by the Gambling Commission. To hold one, the operator submits to identity checks before the first deposit (name, address and date of birth, in force since 7 May 2019), to GAMSTOP enrolment for the customer who asks to be excluded, and to a financial vulnerability check that triggers when deposits minus withdrawals exceed £150 in a rolling 30-day window (in force since 28 February 2025). The latter is a public-record check — bankruptcy registers, county court judgments — not a credit reference and not an income check. The affordability framework the press calls “affordability checks” is a separate, staged plan the Commission announced on 7 July 2026, with no start date. None of this is optional, and the offer sits behind it.

What changed on 19 January 2026

Two promotion rules took effect that day and reshape every welcome offer on this page. Wagering requirements on bonuses are capped at 10x: a £10 bonus can ask for no more than £100 of qualifying bets, whatever the headline reads. Mixed-product promotions are banned: an offer that requires gambling on two or more product types — betting and casino, football and free spins — is no longer permitted as a sign-up or reload promotion. The Commission has not settled whether the wagering cap also applies to free bets that carry no wagering condition, and the operators’ terms are the only source on that point.

The self-exclusion and help options the reader should know

GAMSTOP covers every GB-licensed online bookmaker; periods run six months, one year, five years, or five years with auto-renewal, and after the minimum term the exclusion remains for a further seven years unless the customer asks GAMSTOP to remove it. Betting shops use a separate scheme. The independent help lines are GamCare (with the National Gambling Helpline), GambleAware and the NHS gambling clinics, alongside Gamblers Anonymous. None of them is an offer; all of them sit behind the offer, which is the order this page is written in.

What an Enhanced Odds Offer Actually Is

The phrase “enhanced odds” covers three distinct mechanisms on a British bookmaker’s site, and the marketing pages rarely name which one a punter is looking at. Knowing which is which is the difference between an offer worth claiming and one that wastes a deposit.

Price boost on a specific market

A price boost takes a single price on a named market and pushes it above the comparable price at peer bookmakers — a Premier League favourites line moved from 4/5 to 6/4, a Cheltenham favourite moved from 3/1 to 4/1. The stake is paid normally, the winnings are paid normally, and there is no wagering condition. The catch is in the stake cap and in the markets the boost covers: many are limited to £10 or £20 maximum stakes and to fixtures the operator has pre-selected, so the offer is a higher price on a smaller bet rather than a free ride. The bookmaker’s margin on the boosted selection sits inside the headline number — a 6/4 line that looks generous carries its own overround — and a sharp comparison against another bookmaker’s price on the same selection is the only test that matters.

Enhanced odds welcome offer

A second mechanism rides alongside a deposit-and-bet trigger and pays out free bets rather than a higher price. The trigger is a real-money bet at minimum odds, settled first; the reward is a bundle of free bet tokens credited afterwards, often with an expiry of seven days and a list of markets they may be used on. The £40-in-free-bets-when-you-bet-£20 pattern at Coral and Unibet is the standard form: stake the qualifying bet at minimum odds of 2.0, receive £40 in tokens, use the tokens inside a week. The winnings on a successful free bet are paid back; the stake of the free bet is not. The value of the offer is therefore the average edge on those tokens, not the £40 on the tin.

Accumulator insurance and acca boosts

A third mechanism sits on top of the punter’s own bet rather than replacing it. Acca insurance refunds a stake — usually as a free bet, not as cash — if one leg of a multiple lets the punter down. Acca boosts add a percentage on top of the winnings of a qualifying multiple. Both run on the operator’s own terms: a minimum number of legs, minimum combined odds, a maximum refund, an expiry. William Hill’s Football Acca Boost, for example, scales from 3% on a double to 200% on a twenty-leg acca with a £10,000 cap per online bet, and runs until 30 May 2027; BoyleSports’ Acca Insurance refunds up to £20 as a free bet if one leg of a qualifying acca loses, with bets placed and settled on the same day.

How to Read a Welcome Offer Before Claiming It

The headline number on a sign-up promotion is the smallest part of the offer. The terms behind it decide whether the offer is worth the qualifying bet, and four numbers matter more than the rest.

The wagering multiple and the bonus base

A wagering multiple tells the punter how many times the bonus base must be turned over in qualifying bets before the bonus or its winnings can be withdrawn. The bonus base is whichever figure the terms name — the bonus alone, or the deposit plus the bonus. A 10x multiple on the bonus alone, against a £10 bonus, asks for £100 of qualifying bets; the same multiple on a deposit-plus-bonus base asks for £200 against the same headline. Since 19 January 2026 the multiple is capped at 10x for licensed operators in Great Britain. An offer stating a higher multiple — even one that has been grandfathered into a long-running promotion — is no longer lawful for new customers.

Minimum odds and which bets count

Minimum odds gate which qualifying bets count toward the turnover. A 1/2 minimum is common for free-bet-trigger offers; 2.0 (evens) is the typical threshold for bonus-clearing offers where the headline reads £40 in free bets for a £20 bet. Anything below the threshold is ignored, and a punter who splits the turnover into short-priced favourites may turn the stub flat and not meet the requirement. The check is mechanical: read the terms, count the qualifying bets, do not stray below the line.

Expiry and what happens to unused tokens

A welcome offer’s free bets expire. Seven days is the standard expiry at the bookmakers reviewed here — BoyleSports, Sky Bet, Midnite and BetMGM all run on a seven-day clock, and Coral and Unibet follow the same window for their £40 bundles. A token unused at the close of the seventh day is forfeit; there is no roll-over, and the offer does not convert into a cash balance. The practical reading is that the offer demands the punter’s attention inside a week, and a punter who plans to deposit and walk away loses the value the marketing is raising.

Cap on winnings and stake-return rules

A free bet’s stake is not paid back with the winnings: a £10 free bet at 5/1 returns £50 in profit, not £60 in return. Some offers cap the winnings on top of that — a £10 free bet usable at any odds that returns a maximum of £500 in profit, for example. Both rules are in the terms; both change the effective value of the headline number. An offer that prints £40 in free bets without naming the stake-return rule or the winnings cap is an offer the punter should not yet have read.

Worked example: what a Coral-style welcome offer really asks

Take a £20 qualifying bet at minimum odds of 2.0, settled, returning £40 in free bets that expire in seven days. The Commission caps the wagering multiple at 10x, and Coral’s headline carries no wagering condition on the bonus itself; the £20 qualifying bet is the trigger, the £40 in free bets is the reward. The punter’s job is to use the £40 in tokens inside a week at the markets the terms permit.

If the punter uses the £40 in four £10 tokens on four single bets at average odds of 3.0, the expected return is calculated as follows. Decimal odds of 3.0 give a payout share of 1 / (1/3.0 + 1/(some opposing price)) — taking a typical bookmaker margin of around 5% on a football 1X2 market, that gives a payout share of roughly 95% and a margin of around 5%. The value of a free bet whose stake is not returned, used on a single selection at decimal odds of 3.0, is the free-bet amount multiplied by (odds − 1) divided by odds, multiplied by the market’s payout share — £10 × (3.0 − 1) / 3.0 × 0.95, which gives roughly £6.33 of expected value per £10 token. Across four tokens the expected value is around £25.30, and that is the average outcome the £40 headline is priced at, not a guaranteed payout.

The Commission cap matters here in a different way: it stops a competing bookmaker from offering a 50x turnover on the same bonus — which would have forced the punter into £1,000 of qualifying bets. The 10x ceiling protects the punter from the worst offers rather than rating the best ones.

The Top 10 UK-Licensed Bookmakers With Enhanced Odds

The list below covers ten operators licensed by the Gambling Commission for remote general betting on real events in Great Britain. The order is editorial; no single operator is “the only” licensed bookmaker in Britain, and a place in a comparison is not a licence. The table that follows captures what each operator’s own terms publish about enhanced odds, then the verdicts that come after it spell out what each offer is worth and for whom.

How the operators compare on enhanced odds and welcome offers

The licence numbers are taken from the Gambling Commission’s public register. Each row records what that operator’s own home page or published terms state about enhanced odds as of mid-October 2026; where the operator’s published material does not name a specific boost mechanism, the row records that absence rather than fabricate one. None of the rows should be read as a ranking: a bookmaker with a thin published-boost offering is not necessarily a thin betting product, and the table stops at the boundary the operator’s own terms draw.

bet365 — the broadest boost catalogue on a Commission-licensed site

bet365’s app on the British App Store lists Bet Builder+ alongside Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts that run pre-match and in-play. The licence sits with Hillside (UK Sports) ENC under account 055148-R-331498-002. Where smaller operators run a single weekly enhanced-odds headline, bet365 runs four overlapping boost programmes on the same fixture list, which is why a punter comparing like for like across a Premier League Saturday will usually find a boost at bet365 and not always find one at a competitor. The catch is stake-cap visibility: Super Boosts and Bet Builder+ Winnings Boosts typically carry maximum-stake limits on the boosted selection, and a punter who reads only the headline price misses them. For a bettor who already uses Bet Builder+ for same-game multiples, the layered boost programme is a meaningful add-on. For a punter who wants a simple price on a single market, the same layer is marketing gloss that hides the actual payout.

Star Sports — racing-led boost cadence on a smaller catalogue

Star Racing Limited holds account 009177-R-104555-019, and the operator’s app lists pre-event and in-play Bet Boosts, Daily Specials and Weekend Enhanced Boosts, alongside live in-play prices on football, horse racing, golf and US sports. The catalogue is narrower than bet365’s, and the daily specials rotate around horse racing in particular — a Saturday-afternoon meeting, a midweek all-weather card. For a punter whose betting is horse-racing-led, the Weekend Enhanced Boosts land where the action is; for a punter whose interest is the football Saturday, the same page is thinner. The verdict is fit-for-purpose for the racing-first bettor and ordinary for everyone else.

London Bet — licensed, app-led, light on published boost detail

London Bet is published by Thistle Bet Limited under account 066162-R-340278-004, and the operator states it is licensed and regulated in the UK. The app carries a 17+ age rating on the British App Store. The operator’s published material does not detail a specific boost programme alongside the licence statement; whether that reflects an unadvertised in-app catalogue or a genuinely narrower offering is not established from the home-page terms. For a bettor requiring a Commission-licensed bookmaker, the brand meets the standard; however, the lack of a visible boost catalogue makes it a quieter choice than the high-volume alternatives.

Betmaster — Malta-registered operator on a Commission licence

Betmaster is operated by BM Solutions GB Ltd, registered in Malta, and states it holds Gambling Commission account number 065699-R-339929-002. The home-page terms carry the licence number without an enhanced-odds programme listed alongside it. The brand’s registration outside Great Britain does not weaken the licence — the Gambling (Licensing and Advertising) Act 2014 requires a Commission licence wherever the operator is based if its remote facilities are used in Great Britain — but it does mean the punter should verify the licence on the Commission’s public register before depositing, and the operator’s own terms stop at the licence number. For a bettor cross-checking licences before signing up, Betmaster passes; for one comparing boost programmes line by line, the published terms give less to compare.

Sky Bet — a tokenised welcome on a small qualifying stake

Sky Bet’s welcome offer credits £30 in free bets as three £10 tokens after 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 licence sits with SBG Sports Limited under account 067370-R-341330-005. The headline looks generous — £30 in tokens for a 5p qualifying bet — but the qualifying stake is the lowest on this list for a reason: the operator’s terms require the punter to deposit and bet at least £5 in real money at 1/1 or greater before the tokens arrive, and the tokens themselves carry Sky Bet’s standard free-bet conditions. For a bettor with a small budget who wants to test a Commission-licensed bookmaker with the minimum outlay, Sky Bet is unusually accessible. For a bettor comparing the headline token value against the qualifying outlay, the £30-for-5p headline is the smallest qualifying risk in this list and the most tokenised reward.

LiveScore Bet — broad payments, thin published boost detail

LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay, and runs under account 056859-R-332720-005 with LiveScore Betting and Gaming (Gibraltar) Limited as licence holder. The payments list is the most varied on this page — five distinct methods, with bank-based Open Banking and a modern e-wallet alongside the standard debit-card pair. The operator’s published material does not name a specific enhanced-odds programme in the same detail as bet365 or Star Sports, and a punter choosing on the boost catalogue alone will find more at competitors. For a bettor who values payment flexibility — Revolut Pay customers, Open Banking users — LiveScore Bet’s range is a real advantage; for a bettor choosing on enhanced-odds breadth, the comparison favours the bigger catalogues.

Geoff Banks — independent app on a Commission licence

GB Sports Advisors Limited holds account 054095-R-330366-010 for Geoff Banks, and the app offers live in-play prices and ante-post prices on future events. The published material is lighter than the major brands’ catalogues and reads closer to a high-street independent than to a national operator: live in-play and ante-post are named, but a layered boost programme is not. For a punter who wants a smaller, named-individual bookmaker with a Gambling Commission licence, Geoff Banks fits. For a punter reading the enhanced-odds comparison as a catalogue race, the brand sits at the back of the field by published breadth.

Midnite — modern site with acca builder and price boosts

Midnite Limited holds account 101839-R-342850-001, and the operator’s home page shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. The site reads as a younger product than the legacy brands: the in-play page sits at the top, the boosts run with stake caps visible, and the welcome offer pays £25 in free bets and 50 free spins to new customers who bet £5 or more on pre-match odds of EVS (2.0) or greater within 14 days of sign-up, valid for 7 days. For a punter who bets accumulators and wants the builder alongside the boosts, Midnite bundles the two cleanly; for a bettor who only bets singles on racing, the same package is over-built for the use.

BetMGM — split-token welcome tied to specific bet types

BetMGM’s UK welcome offer is four £10 free bets — two football accumulators of 4+ selections and two sports multiples of 2+ — credited after a £10 deposit and a sports bet within 7 days, valid for 7 days with minimum odds and opt-in required. The licence sits with LeoVegas Gaming PLC under account 039198-R-319450-029. The token structure is unusually prescriptive: not £40 in free bets usable on anything, but £40 split into four tokens each tied to a specific bet type, with each type carrying its own minimum-leg threshold. For a bettor who already bets football accas and sports multiples, the token structure mirrors the betting; for a bettor who bets singles, two of the four tokens are unusable as written and the headline reads shorter. The headline ranks above the headline at competitors for an acca-first bettor and below it for a singles-first one.

Betfred — legacy operator with free-bet terms in-app

Betfred advertises new-customer free bets and free spins subject to terms, with responsible-gambling information and GambleAware support contacts in-app, under account 039544-R-319290-010 with Petfre (Gibraltar) Limited as licence holder. The published terms on the home page stop short of the headline figures the in-app offer carries, and a punter comparing prize claims is settled in-app rather than from the operator’s home page. For a bettor with a Betfred shop habit who wants the online arm under the same name, the licence test is met and the in-app terms are the ones that govern the offer. For a bettor who reads the home page as the offer, the published material reads unfinished.

The Other Enhanced-Odds Brands Worth Knowing

The table and verdicts above cover ten Commission-licensed bookmakers. The British enhanced-odds market runs wider than ten, and four further operators recur in the comparison: Coral and Unibet on the £40-in-free-bets-when-you-bet-£20 pattern, BoyleSports on acca insurance and acca loyalty, Kwiff and Spreadex on Supercharge-style boosts, William Hill on Football Acca Boost, and Smarkets/SBK, QuinnBet and BetVictor on token structures that overlap with the ten above. They are described here on the same terms as the ten: what each operator’s own terms state, what the offer actually pays back, and where the catch sits.

Coral — the £40-in-free-bets benchmark

Coral’s sports welcome offer is “Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue, for new GB customers who opt in. The qualifying payment must be a debit card or instant bank transfer. Beyond the welcome, Coral offers a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games including Football Super Series with a £10,000 jackpot. The £40 headline is the most-quoted enhanced-odds welcome on the British market and the one other operators measure themselves against. For a punter with £20 to risk at minimum odds of 2.0, the headline is competitive on the qualifying-bet cost and unambiguous on the reward.

Unibet — Best Odds Guaranteed and a Uniboost cadence

Unibet’s UK sports welcome offer mirrors Coral’s headline: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with free bets expiring within 7 days of issue, for new GB customers using a debit card or instant bank transfer. The site also offers Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets. The combination of Best Odds Guaranteed on racing, daily Uniboosts and a £40 welcome is the strongest racing-led package in this comparison. For a horse-racing punter, Unibet’s BOG + Uniboosts + £40 welcome covers the racing calendar; for a football-only punter, the same package is heavier on racing than the punter needs.

BoyleSports — acca insurance and acca loyalty with a tight window

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed (€30 in free bets for a €10 bet for Irish players). The acca-side offers are the differentiator: Acca Insurance requires opt-in, a minimum stake of £5, minimum odds of 1/2, and pays a maximum refund of £20 as a free bet that expires in 7 days, with bets placed and settled on the same day; Acca Loyalty requires opt-in, a £5 minimum stake, minimum combined odds of 3/1 and 5 or more settled legs, with a free bet expiring after 7 days. For a punter who already bets accas, the insurance + loyalty stack converts one losing leg into a follow-up bet and pays extra on winning ones. For a singles-only punter, the same offers are unreachable as written.

Kwiff — Supercharge as the headline mechanic

Kwiff’s Supercharge feature can instantly boost the odds on a bet, for example from 2/1 to 20/1, and it can apply to single or multi bets on any sport. The brand also offers Bet Builder and Bet Builder+ (combining Bet Builder bets from different games) and a guaranteed weekend acca boost. For a punter who likes the surprise of an instantly-boosted price and bets across sports, Supercharge is the differentiator. For a punter who reads the marketing as a guaranteed higher price, the surprise is the point and the unpredictability is the cost.

Spreadex — fixed-odds plus spread betting under one licence

Spreadex’s new customer offer is £60 in free bets for a £10 fixed-odds bet, with the free bets usable across fixed odds and spread betting; the qualifying bet must be placed within 28 days of opening the account, and the qualifying fixed-odds bet carries minimum odds of 1/2. The brand is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting, and warns that spread betting losses can exceed the deposit. Beyond the welcome, Spreadex’s Acca Boosts give a cash boost from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs. For a punter who wants both fixed-odds betting and spread betting on one licence, the £60-in-free-bets headline and the acca-boost range are unusually generous; for a punter who only bets fixed-odds singles, the spread-betting half of the licence is a warning rather than a feature.

William Hill — Football Acca Boost on a published scale

William Hill’s Football Acca Boost covers accas of 2 or more legs with each selection at 1/5 or bigger, with a boost from 3% on a double up to 200% on 20 or more legs, a maximum boost of £10,000 per online bet, and runs until 30 May 2027. The 200% ceiling and the £10,000 cap are the largest published acca-boost figures in this comparison. For a punter who bets football accas of meaningful size, the Acca Boost’s scaling pays back more at the upper end than competitors publish. For a punter who bets doubles, the 3% baseline is ordinary and the headline reads better than the doubles-book delivers.

SMARKETS, QuinnBet, BetVictor and DAZN Bet — the secondary tier

• Smarkets (SBK). SBK’s UK welcome offer is a £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours, with Cash Out, Bet Builder and live horse racing streams. For a bettor who wants an exchange-rooted sportsbook with the same licence test passed, SBK is the cleanest comparison to Smarkets’ exchange.
• QuinnBet. QuinnBet free bets are valid for 7 days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. The 50/1 ceiling is unusual — most free-bet terms cap lower — and is worth reading carefully before staking.
• BetVictor. BetVictor offers regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by its customer terms and conditions. For a bettor comparing across the legacy brands, BetVictor’s terms sit between Unibet and Betfred on published detail.
• DAZN Bet. DAZN Bet offers Cash Out, Bet Builder, daily bet boosts and in-play betting, with cash-out availability not guaranteed and bets standing if cash-out is unavailable. The brand also provides deposit limits, loss limits and wagering limits as safer-gambling tools. For a bettor who values named safer-gambling controls on the operator’s help pages, DAZN Bet publishes them explicitly.

The Legal Frame Behind Every Offer

Every offer in this review sits inside a licence the operator holds from the Gambling Commission. The licence is the test that decides which brands appear on this page, and the licence frame is what stops an enhanced-odds comparison from drifting into a marketing round-up.

What the Gambling Commission does

The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport. It licenses the whole commercial market in Great Britain under the Gambling Act 2005. The Act covers England, Scotland and Wales; Northern Ireland is outside the Act and runs on its own older law, so a GB licence is not a Northern Ireland licence. 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 — sections 33 and 36 of the 2005 Act as amended — and a Curaçao, Maltese or Gibraltar licence is not a substitute for one. The Commission’s public register is searchable by business name, trading name, domain or account number, and the register is the only place the licence can be verified.

The licence categories a punter sees on the register

A Commission licence carries a category. The brands in this review operate under “remote general betting standard (real events)” — the standard sportsbook licence for real-world sport. Other categories exist: remote general betting standard (virtual events) covers computer-simulated events; remote general betting limited covers smaller operators with restricted offerings; remote pool betting covers pool products on horse and dog racing; remote betting intermediary covers betting exchanges. Reading the licence category on the register confirms the operator is licensed for the product the punter is buying; a sportsbook licensed only for virtual events is not licensed to take real-event bets.

The customer-protection rules attached to the licence

Identity verification before the first deposit (since 7 May 2019) — name, address and date of birth, including with a free bet or bonus — means no anonymous play at a licensed site. Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet payments; debit cards and bank-based payments are not covered by that ban. GAMSTOP enrolment is a mandatory licence condition for online operators since 31 March 2020, with periods of six months, one year, five years, or five years with auto-renewal and a seven-year tail after the minimum term. A financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) triggers when deposits minus withdrawals exceed £150 in a rolling 30 days; the check is a public-record check, not a credit reference and not an income check.

The advertising rules that surround the offers

Advertising is not licensed by the Commission. It runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the Commission’s LCCP marketing conditions. CAP Code section 16 keeps marketing socially responsible, keeps it out of strong appeal to under-18s, and bars anyone who is or seems to be under 25 from featuring in the ad or playing a significant role. The rule concerns who may appear in the advertisement rather than who may bet. “Whistle-to-whistle” is an industry code rather than law: since 1 August 2019 betting advertisements have not been shown on TV from five minutes before a live sporting event to five minutes after it, before the 9 pm watershed, with horse and greyhound racing excluded. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts (from the 2026/27 season, with sleeves and hoardings remaining) is voluntary rather than law. Operators are responsible for marketing run by their affiliates.

What is taxed, and on whom

The player pays no tax on betting winnings in Great Britain — general information, not tax advice, and a professional gambler should ask HMRC or an adviser. General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within General Betting Duty, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15% (HM Government policy paper of 26 November 2025). Until 1 April 2027 the remote rate stays at 15%. Whether operators pass duty on through odds is not established, and a punter reading odds at a licensed site is not being charged duty. The Commission’s statutory levy is a separate charge on operators, not a tax.

Why offshore brands do not appear on this page

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, with penalties on summary conviction of up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland). No offence aimed at a customer who merely bets on an unlicensed site was found in the framework research, but the practical loss is significant: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and not bound by the 10x bonus cap or the £150 vulnerability check. Enforcement is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, with the Commission given or about to receive court-order DNS blocking powers. The honest framing is that licensed means checks, limits, GAMSTOP and the bonus cap — and verification before the first bet — while unlicensed means none of those protections and possible loss of funds. Neither is “the safe choice” by default, and an unlicensed brand is not a candidate for this comparison.

How This Comparison Was Built

Three rules governed the inclusion of every operator on this page. The first is the licence: every brand sits on the Commission’s public register against a remote general betting standard (real events) licence. The second is the published terms: every fact in the operator verdicts comes from that operator’s own home page, App Store listing or published help-centre entry as of mid-October 2026. The third is the offer shape: every welcome offer in scope takes the form of free bets, free spins, acca insurance, acca boosts or price boosts, rather than a deposit-match bonus with a high wagering multiple — and the Commission’s 10x cap from 19 January 2026 is the reason that third rule is shorter than it used to be.

What was deliberately left out

No promo code, voucher or sign-up link appears on this page, by design. The Commission’s LCCP and the ASA’s CAP Code both govern how offers are marketed, and this comparison reads the offers as published terms rather than reproducing the marketing collateral. Where an operator’s published terms are thin — London Bet, Betmaster, Geoff Banks — the verdict records the absence rather than reaching for a comparable number. A bettor who wants the live offer terms opens the operator’s home page; a bettor who wants the licence test passed checks the Commission’s public register.

What the punter should do before claiming

Three checks, in this order. First, the licence: open the Commission’s public register and confirm the licence number the operator’s home page publishes against the register’s entry. Second, the terms: open the operator’s published terms and read the wagering multiple (capped at 10x since 19 January 2026), the minimum odds, the expiry on free bets and the winnings cap. Third, the bank: set a deposit limit on the operator’s safer-gambling page before the first deposit, and use GAMSTOP if self-exclusion is the right answer. The offer comes fourth, not first.

Frequently Asked Questions

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

The Gambling Commission’s promotion rules, in force since 19 January 2026, cap the wagering requirement on a bonus at 10x. A £10 bonus can ask for no more than £100 of qualifying bets; a £50 bonus for no more than £500. Free bets with no wagering condition are not covered by the published rule, and the operator’s own terms are the only source on that point. Mixed-product promotions — an offer requiring gambling on two or more product types — are banned under the same rules.

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

Minimum odds gate which bets count toward the turnover needed to clear a bonus. A 1/2 minimum is common for free-bet-trigger offers; 2.0 (evens) is the typical threshold for bonus-clearing offers. The wagering requirement is the multiple of the bonus base (the bonus, or the deposit plus the bonus) that must be turned over in qualifying bets before winnings can be withdrawn. Under the Commission’s 10x cap, a £10 bonus cannot carry a wagering requirement above £100 of qualifying bets.

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

A free bet is a token with a face value, not a cash stake, and the operator’s terms exclude the token itself from the return. A £10 free bet at decimal odds of 4.0 returns £30 in profit, not £40 in return. The effective value of the free bet is therefore the expected profit at the operator’s payout share, not the headline token value, and the difference is the cost the marketing headline does not show.

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

No. The Commission’s promotion rules in force since 19 January 2026 ban mixed-product promotions: an offer that requires gambling on two or more product types, such as betting on football to unlock free spins on a casino game, is no longer permitted. Betting offers and casino offers must be structured as separate promotions rather than as a single sign-up bundle.

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

The Commission’s public register is searchable by business name, trading name, domain or account number at the Commission’s website. The register lists the licence category (for this page’s operators, remote general betting standard — real events), the licence holder, the trading name and the domain. The licence number an operator publishes on its home page should reconcile to the register’s entry on the same number. The register is the test; an operator’s own claim to be licensed is not.

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

Betting winnings are not taxed on the punter in Great Britain — general information, not tax advice, and a professional gambler should ask HMRC or an adviser. General Betting Duty is the operator’s tax on gross profits, currently 15% with a 25% remote rate from 1 April 2027; whether operators pass the duty on through odds is not established, and a punter reading odds at a licensed site is not being charged duty. The Commission’s statutory levy is a separate charge on operators, not a tax.
