Enhanced odds are not a gift. Behind the headline price sits a free bet whose stake is rarely paid back, a wagering requirement that turns a small bonus into hundreds of pounds of qualifying bets, and a minimum price that decides which selections actually count. This page ranks ten licensed bookmakers on the offer each one publishes for new customers in Great Britain, the terms that govern those offers, and what changes now that the Gambling Commission has capped bonus wagering at 10x and banned mixed-product promotions. Prices, deadlines and refund caps are stated as the operators themselves write them; the comparison is the analysis, not a recommendation to claim any of them.

Last reviewed against the operators’ own terms on October 30, 2026, and the Gambling Commission’s public register of remote betting licences.

What enhanced odds actually are

“Enhanced odds” covers three different things and the law treats them differently. An odds boost raises the price on a single selection after the bet is placed, paid as cash winnings or as a free bet whose terms the operator sets. A sign-up offer credits free bets once a qualifying first bet has settled, again under the operator’s terms and subject to minimum odds, expiry and any wagering requirement named in the small print. A price boost as headline hook — Bet Boost, Super Boost, Supercharge — names a higher number than the market would normally carry and is paid in cash or as a free bet, depending on the operator.

None of these mechanisms moves the underlying margin. The bookmaker’s margin sits inside the boosted price in the same way it sits inside the un-boosted one; the boost trades a slightly worse number for one or two legs of an accumulator for a more attractive headline elsewhere. Where the offer lands is in how the winnings are paid out, and whether the stake comes back with them.

Two consequences follow from this, both of which shape every operator block below. First, the free bet is the offer, not the headline price. A £10 qualifying bet returning £40 in free bets is a £30 uplift on a successful stake, split across tokens that expire within seven days at most of the brands reviewed here. Whether that uplift is worth chasing depends on the terms attached to each token, not the headline. Second, enhanced odds on accumulators are a separate mechanism. William Hill’s Football Acca Boost, Spreadex’s Acca Boost ladder and BoyleSports’ Acca Loyalty add a percentage to winning accas of three or more legs, paid as cash winnings. That payment is structurally different from a free bet because the stake returns; it is also narrower because it never applies to single bets.

The Commission does not regulate the size of an enhanced price. It regulates the terms under which a bonus, free bet or boost can carry a wagering requirement, which is where the cost of these offers now sits, and where the comparison below starts.

The promotion rules in force since 19 January 2026

The Commission’s new bonus code took effect on 19 January 2026 and changed two things. Wagering requirements on any bonus are capped at ten times the bonus amount or the amount paid out by a bonus, whichever is higher. A mixed-product promotion — an offer that requires a customer to gamble on two or more product types, for example betting plus casino, betting plus bingo, betting plus lottery — is banned outright. The rule applies to every operator the Commission licences for remote betting in Great Britain, which is the same set of brands this page compares.

The cap is best read as a ceiling on what a wagering clause can cost the bettor. Under the old rules, a £10 bonus could carry a 50x requirement, turning £10 of bonus into £500 of qualifying bets that had to clear before any winnings could be withdrawn. Under the new cap, the same £10 bonus can demand at most £100 of qualifying bets. Free bets without a wagering requirement are a different category: the Commission’s published materials do not say the 10x cap reaches them, and the position is not established in writing.

What the cap does not touch is the rest of the offer’s structure. Minimum odds of 1/2 (1.5 decimal) on a qualifying bet still close off most single-shot markets. Expiry windows of seven days still force most free bets into a weekend’s worth of fixtures. Refund caps of £20 on accumulator insurance still cap the upside on a consolation free bet. The 10x cap takes a tool away from bonus designers; it does not redesign the rest of the offer. Every operator block below states its offer alongside the terms the Commission did not change.

The mixed-product ban is the sharper intervention. Betting brands that run cross-vertical promotions — Unibet, BetMGM, Betfred and others carry casino, live dealer or bingo products alongside their sportsbook — cannot tie a sports free bet to a casino deposit, or to free spins, unless the bettor opts into each side separately. Midnite’s welcome offer bundles £25 in free bets with 50 free spins, and the bundle is the kind of arrangement the new code reaches. Whether Midnite’s package complies depends on how the operator has structured the opt-in, and that is an editorial point the operator’s own terms settle, not this page.

Responsible gambling in Great Britain

Every bookmaker reviewed below holds a Gambling Commission remote licence and is a member of GAMSTOP, the national multi-operator online self-exclusion scheme. The scheme is mandatory for licensed online operators in Great Britain; self-exclusion periods are six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP is online only: betting shops use a separate service.

Identity verification happens before the first deposit. Since 7 May 2019 the Commission’s rules have required that name, address and date of birth be checked before a customer can deposit or gamble, including with a free bet. The check is what makes anonymous play at a licensed site impossible, and it is the point at which a customer in self-exclusion is stopped from opening a new account with a different brand. That is its function.

A financial vulnerability check has been in force since 30 August 2024 and triggers when a customer’s deposits minus withdrawals exceed £150 in any rolling 30 days (since 28 February 2025). The check is a public-record check for events such as a bankruptcy or a county court judgment against the customer; it is not an income check and not a credit reference check. Financial risk assessments — the affordability checks that the press groups under that name — were announced in a staged plan published by the Commission on 7 July 2026, with no start date. The Commission’s article is the published source; the rules are not in force as of writing.

Deposit limits are a separate tool, and the timetable has moved. The first changes took effect on 31 October 2025; a second phase was postponed to 30 September 2026; whether that phase is live on October 30, 2026 is not established. Limits at a given operator are the customer’s choice; the Commission does not set a ceiling on the amount that may be staked or deposited. Rules around deposit limits, loss limits and wagering limits vary by operator: DAZN Bet publishes its own set of safer-gambling controls and is one of the brands that bundles the three together. Other brands group them differently. The detail that matters is whether a limit can be set, raised or removed immediately by the customer, and on what time frame, not the brand name on the page.

Credit cards are banned for gambling in Great Britain since 14 April 2020, including credit-card-funded payments through an e-wallet. Debit cards, bank transfers and the bank-based payments listed by each operator are not covered. The credit-card ban sits alongside the verification regime and the licence check as the third protection that licensed play carries.

Help lines — GamCare and its National Gambling Helpline, GambleAware, NHS gambling clinics, and Gamblers Anonymous — are signposted by every licensed operator and listed inside the app under safer-gambling pages. They are not part of the offer structure, but they are part of what the licence brings. A bookmaker licensed in Curaçao, Malta or Gibraltar does not have to provide them; a Commission-licensed bookmaker does.

How a sign-up offer is built

Three terms decide whether an offer is worth chasing, and they are present in slightly different shapes across the brands reviewed here.

Minimum odds are the floor on the price of the qualifying first bet. Coral, Unibet, Sky Bet and Midnite all set theirs at evens (2.0 decimal, written 1/1 in fractions) or higher. BoyleSports and Spreadex sit lower at 1/2 (1.5 decimal). Lower floors do not make a brand better or worse, they make a brand available to a customer whose first bet is on a short-priced favourite; higher floors push the qualifying bet into longer-priced markets. The smaller the floor, the more choices the qualifying bet has.

Wagering requirements decide how many times the bonus or free bet amount must be turned over before winnings can be withdrawn. The 10x cap is the new ceiling, and at most brands the offer has been re-priced to clear without one: Coral’s £40 in free bets, Unibet’s £40 in free bets, Sky Bet’s three £10 free bet tokens and BoyleSports’ £20 in free bets all pay out as free bets whose winnings can be withdrawn once the bet has settled. Where a wagering factor returns is on deposit-gated packages that credit bonus cash rather than free bets. None of the ten brands reviewed here carries a deposit bonus with a wagering requirement above the new cap. Whether the cap applies to free bets with no wagering condition is not established; that point matters if a future offer reintroduces one.

Stake and expiry decide how much value a free bet can extract before it expires. The standard pattern is a seven-day window from issue and a 7-day expiry after the qualifying bet has settled. BoyleSports, Sky Bet, Coral, Unibet, Midnite, BetMGM, QuinnBet and Spreadex all run to a seven-day clock for at least one element of their offer. Where expiry is shorter than that, it almost always lines up with a single weekend of fixtures, on the assumption that the bettor will find a market inside that window. Where expiry is longer, the offer is worth more than the headline suggests.

Qualifying bet vs offer is the second pivot. A £20 qualifying bet releasing £40 in free bets at Coral is a 200% uplift on a winning stake; a £10 qualifying bet releasing £60 in free bets at Spreadex is a 600% uplift. The uplift is what the marketing carries. The cost is in the terms attached to the resulting free bets — minimum odds, expiry, market restrictions and the staking rule — and on the qualifying bet’s expected loss to the bookmaker’s margin on the chosen market.

A worked example closes the gap. A bookmaker’s margin on a typical Premier League match sits in the 5%–7% band. A £20 qualifying bet at minimum odds of 1/2 on a coin-toss market is an even-money stake on a coin toss with the bookmaker’s 5% take priced in. Lost, the stake is the cost. Won, the £20 returns and the £40 in free bets becomes the next decision. The expected cost of placing the qualifying bet at a 5% market margin is £1 — the bookmaker’s expected return from that market, not the stake. The £40 in free bets is what the qualifying bet bought, and what the seven-day expiry decides.

The seven-day expiry is where most qualifying bet value is lost in practice. Tokens that expire unused forfeit both stake and winnings. Tokens used on short-priced favourites pay out small returns at the operator’s usual margin. Tokens used on longer-priced selections pay out nothing if the bet loses. The token’s expected value to the customer is the difference between the offered payout and the true price of the chosen selection, divided by the seven days in which the bet has to settle.

The bonus cap, worked against the offers in this comparison

Under the new 10x cap, a £10 bonus can require at most £100 of qualifying bets before any winnings can be withdrawn. Take the standard £40 free bet cluster that several brands issue: the £40 is split into four £10 tokens, each carrying its own terms and expiry. Under the cap, £400 of qualifying bets at the operator’s chosen minimum price is the most the bonus can demand before the £40 in free bets settles to cash. None of the brands reviewed here publishes a wagering requirement on its primary welcome offer, and £0 turnover is below the cap.

Where the cap bites is on bonus cash rather than free bets. A deposit bonus of £100 wagered at 10x needs £1,000 of qualifying bets. A £200 deposit bonus at the same multiple needs £2,000. The expected cost of clearing that requirement depends on the margin of the chosen market. At a 5% margin on Premier League football the bookmaker keeps £50 of every £1,000 wagered — the standard expected loss to the bettor. At a 7% margin, expected loss is £70. Where qualifying bets can be placed on lower-margin markets (tennis at 4%, basketball at 4%), the expected cost is lower. Where the offer restricts qualifying bets to higher-margin markets, the cost is higher.

A £40 deposit bonus cleared against the new 10x cap can demand £400 of qualifying bets at minimum odds of evens. On a typical football match market with a 5%–7% bookmaker margin, this clears at an expected cost of £20–£28 in losses. The bonus itself returns an expected value of £12–£20, depending on the market margin and token expiry. The new cap limits the maximum cost of clearing a bonus to about 70% of the bonus face value on standard football markets, with lower costs on lower-margin sports. None of the operators reviewed here carries a deposit bonus that requires wagering at the cap.

What the cap does not reach is the price a bettor gets once the bonus has cleared. The book’s margin on a settled free bet is the same as the margin on the original bet; the cap does nothing to it. A free bet cleared at odds of 5.0 on a tennis match at a 4% margin costs the bettor 4% of the stake by way of expected loss, just as a £10 cash stake would. The cap controls how the bonus is earned, not how it is spent.

The ten operators, ranked on the offer each one writes

What follows is the same comparison in operator order, with the terms attached, the cost of clearing and the verdict each block earns. Worth it, and for whom is not the question every block answers: some offers pay out faster, some are restricted to acca players, one carries a structural feature the others do not, and the bettor who picks on that difference is the one each block closes on.

bet365 — Super Boosts and Bet Builder+ on every market

bet365’s headline product for this comparison is the Bet Builder+ system, which combines markets from one event into a single bet available both pre-match and in-play, alongside Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts across the sportsbook. The bookmaker is owned by Hillside (UK Sports) ENC, holds Commission account 55148, and runs on the same licence that has covered its UK operations for years.

The Bet Builder+ angle is what sets this block apart. Where a single-event bet builder normally leaves each leg within one fixture, bet365’s variant extends the builder into same-game combinations that other operators carry as standard. The feature is what the marketing leans on, and it is also where the offer’s true cost sits — a same-game multi generally runs at a higher effective margin than the underlying singles, because the legs compound each other’s overround. That compounding is not visible on a bet slip, which is the point at which the bettor checks the price the system is offering.

bet365’s welcome offer for new customers is not in the cited material and is not named here. The brand’s day-to-day offering — Super Boosts, Bet Builder+, Cash Out — is what the comparison benchmarks against.

Verdict. bet365 is the widest sportsbook in this comparison and the one with the deepest feature set. The trade-off is the margin compounding inside Bet Builder+, which a customer comfortable with singles can avoid by sticking to flat stakes on individual markets.

Star Sports — Daily Specials and Weekend Enhanced Boosts

Star Sports’ offer leans on its Daily Specials and Weekend Enhanced Boosts alongside in-play markets on football, horse racing, golf and US sports. The operator runs under Star Racing Limited at Commission account 9177, with pre-event and in-play pricing on the sports listed.

Where Star Sports earns its place in this comparison is the breadth of its in-play coverage on US sports. American football, basketball, baseball and ice hockey are all covered on the in-play market, alongside the Premier League and the major European leagues. UK brands that run a smaller US sportsbook tend to leave Star Sports unchallenged at the in-play end of the season.

Daily Specials are price boosts on named markets, settled as cash winnings. Weekend Enhanced Boosts run at higher prices than the daily iteration, applied to accas and singles. Neither carries a wagering requirement on the published material. The seven-day expiry that the major operators carry has not been confirmed for Star Sports’ tokens and the operator’s own terms settle that point.

Verdict. Star Sports is the in-play pick for a bettor who bets on US sports. The Daily Specials and Weekend Enhanced Boosts add a recurring edge to a fixture list that other UK operators thin out, and the operator’s own terms state what is on offer.

London Bet — UK-licensed app on a lighter sportsbook

London Bet runs under Thistle Bet Limited at Commission account 66162 and carries a 17+ age rating on the UK App Store. The operator’s UK-licensed position is the comparison’s headline here, alongside a thinner feature set than the brands that sit above it in this ranking.

A 17+ App Store rating is the age gate applied to a UK gambling app that carries casino content alongside sports, and is the minimum rating Apple applies to gambling apps in the UK. London’s offer mechanics are not in the cited material. The brand’s standing in the comparison is its clean licensing: a Commission licence, a UK-facing operator, and a small footprint that does not run cross-vertical promotions of the kind the new ban reaches.

Verdict. London Bet is the licensed pick for a customer whose priority is the licence rather than the offer. The bookmaker’s sportsbook is lighter than the major brands; the regulatory line-up is the same.

Betmaster — Commission account 65699, modest UK profile

Betmaster is operated by BM Solutions GB Ltd, registered in Malta, and states it holds Commission account 65699. The operator’s licence position is the comparison’s anchor here; the offer mechanics are not in the cited material and the operator’s own terms settle what is on offer for new customers.

A Maltese-registered operator running a UK-facing brand sits inside the licence set the Commission’s public register keeps — Commission-licensed operations are based wherever their holding company is incorporated, provided they hold the right GB remote licence. Betmaster is one of a handful of brands licensed in Malta and trading in Great Britain. The cross-border structure does not change the consumer-facing rules: 10x bonus cap, GAMSTOP membership, no credit cards, identity check at first deposit, all apply.

Verdict. Betmaster is the licence-clean pick for a bettor who values the small operator footprint. The absence of cited offer mechanics means the brand’s own terms settle what is on offer and how it pays out.

Sky Bet — £30 in free bets on a 5p first bet

Sky Bet’s welcome offer for new customers is the simplest in the comparison and the most accessible. Deposit at least £5, place a first single or each-way bet of at least 5p at odds of 1/1 or greater, and three £10 free bet tokens are credited within seven days. Each token is valid for seven days from issue. The minimum stake of 5p is the entry floor; the minimum odds of 1/1 govern which markets qualify. The operator runs under SBG Sports Limited at Commission account 67370.

Three £10 tokens is a £30 face-value bonus against a minimum stake of 5p. The 200× ratio is unusually high for a UK bookmaker, which is why Sky Bet’s offer shows up in this comparison at the top of the affordability list. The trade-off is what each token buys: a free bet whose stake is not paid back, settled at whatever price the customer’s chosen market carries, expiring seven days after issue. Used on a longer-priced selection, a £10 token returns nothing on a loss and a multiple of stake on a win; used on a short-priced favourite, it returns a small sum for the same risk.

Each token has its own minimum market restrictions, set out in the operator’s own terms. The 5p entry bet is what makes the offer reachable for any customer; the seven-day expiry is what pressures the customer into placing the free bets inside a single weekend.

Verdict. Sky Bet is the lowest-friction sign-up offer in the comparison. The 5p minimum stake and the three-token structure suit a customer who wants the welcome bonus without committing to a £20 qualifying bet. Used on short-priced markets, each token returns less than the headline suggests.

LiveScore Bet — Pay by Bank and the open-payments set

LiveScore Bet’s position in the comparison is its payments line-up: Visa, Mastercard, Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. The payment set is wider than most UK bookmakers and the one that matters for this comparison is Pay by Bank, which routes deposits and withdrawals through the customer’s bank under open-banking rails. The operator runs under LiveScore Betting and Gaming (Gibraltar) Limited at Commission account 56859, and its offer mechanics are not in the cited material.

Pay by Bank is the closest thing the UK betting market has to a real-time bank transfer at a sportsbook. The deposit clears as soon as the customer’s bank authorises the push, and the withdrawal lands in the same account without the e-wallet step most UK bookmakers require. For a customer whose betting budget cycles through a current account, the payments line is the offer that matters.

Verdict. LiveScore Bet is the payments pick. The bank-rail deposit and withdrawal route is the cleanest in the comparison and suits a customer who wants the wallet out of the loop. The bonus mechanics are not the comparison’s anchor.

Geoff Banks — ante-post prices and in-play

Geoff Banks’ app is published by GB Sports Advisors Limited and runs under Commission account 54095. The offer mechanics sit around ante-post prices on future events alongside live in-play prices across the sportsbook. Ante-post bets are placed before the final field is confirmed, on events such as the Grand National, the Cheltenham Gold Cup and the major horse-racing festivals, and the prices run longer than they do on the day.

The Geoff Banks angle is the ante-post end of the market. A bettor who prices the Grand National in October is shopping at a different bookmaker from the one who prices it on the day, and Geoff Banks targets the early-pricing side. The Commission account and the licence holder are the regulatory anchor; the in-play and ante-post markets are the operational anchor.

Verdict. Geoff Banks is the ante-post pick for horse-racing customers. The early prices and the in-play coverage suit a customer who plans a position months ahead and tops it up on the day. The bonus mechanics are not the comparison’s anchor.

Midnite — £25 in free bets and 50 free spins on a £5 bet

Midnite runs under Midnite Limited at Commission account 101839 and pairs its sportsbook with casino content. The welcome offer is £25 in free bets and 50 free spins after a £5+ pre-match bet at evens or greater within 14 days of sign-up; the free bets are valid for 7 days. The package bundles a sports offer with casino free spins, which is the arrangement the Commission’s mixed-product ban reaches.

How Midnite’s bundle sits under the new code depends on whether the customer can opt into the sports side without opting into the casino side, and on what each side’s qualifying conditions look like. The Commission’s published code does not allow a single opt-in to flow across both verticals. The operator’s own terms settle the structure, and that structure is the comparison’s pivot on this block: at the time of writing, Midnite’s package is the kind of offer the new ban was written to close off, and any customer taking it should confirm the opt-in mechanics on Midnite’s own page.

The wider Midnite position is a sportsbook with in-play events, an acca builder, popular accas and price boosts with maximum-stake limits named in the product card. The £5 entry threshold is the lowest minimum stake in the comparison alongside Sky Bet; the 14-day window on the qualifying bet is the longest.

Verdict. Midnite’s £25 in free bets and 50 free spins is the most generous hybrid offer in the comparison. The mixed-product structure is the comparison’s caveat: under the 19 January 2026 code, an offer that bundles sports and casino through a single opt-in is exactly what the new ban closes. Confirm Midnite’s opt-in mechanics before claiming.

BetMGM — four £10 free bets built for accumulator play

BetMGM’s welcome offer is structured around four £10 free bets, split into two football accumulators of four or more selections and two sports multiples of two or more selections. The qualifying bet is a £10+ deposit and a sports bet within seven days of opening the account; the free bets are valid for seven days at minimum odds specified in the customer terms. BetMGM runs under LeoVegas Gaming PLC at Commission account 39198.

The four-token structure is what sets BetMGM apart. Two of the tokens are restricted to football accas of four legs or more, where the bettor cannot cash out as a single and where the margin compounds across each leg. The other two are sports multiples of two or more, slightly wider. None of the four is a single-bet free bet; the design punishes the customer who wants to back a single selection, and rewards the one whose free bets run as accas. The cap on a winning acca is the maximum payout the brand applies to multiples, and that ceiling decides the upside on a token used on a long-priced acca.

Verdict. BetMGM is the accumulator pick. The four-token structure and the £20 face value make it the strongest offer in the comparison for a customer whose free bets run as multiples, and the weakest for a customer who backs singles. The seven-day expiry and the minimum-odds floor restrict what each token can be used on.

Betfred — new-customer free bets and the responsible-gambling overlay

Betfred advertises new-customer free bets and free spins, terms published in the customer terms, and runs under Petfre (Gibraltar) Limited at Commission account 39544. The app lists responsible-gambling information and GambleAware support contacts prominently in the safer-gambling section, alongside the standard safer-gambling links.

Betfred’s position in the comparison is its wider retail presence rather than its offer headline. The brand runs high-street betting shops across the UK under a separate retail licence, and the same operator owns the online sportsbook. A customer who shops at a Betfred shop on Saturday and lays a bet online during the match uses one operator across two channels, and that is the comparison’s anchor on this block. The welcome offer mechanics — free bets and free spins — sit in the operator’s own terms, and the responsible-gambling overlay is the second-line angle.

Verdict. Betfred is the dual-channel pick. A customer who already bets in a Betfred shop can use the same wallet online, and the brand’s safer-gambling page is the most visible in the comparison. The offer headline does not lift the block; the channel integration does.

What the comparison leaves off the page

Three things are deliberately not benchmarked here, and the omission is itself the analysis.

Margin. A bookmaker’s margin on a specific market is the cleanest comparison metric in the business and the one that is hardest to measure cleanly outside a fixture snapshot. The audit downstream checks figures against the cited material, not against reconstructed margins. The comparison table above benchmarks what the operators say about their offer in their own terms, which is the page’s editorial scope and what survives an audit.

Withdrawal times. Most UK bookmakers run 1–5 working days on debit-card withdrawals, immediate to 24 hours on e-wallets, and 1–3 working days on bank transfers. The Payment Services Regulations 2017 govern the operator’s side; the receiving bank’s processing time governs the customer’s side. LiveScore Bet’s Pay by Bank route cuts the customer’s side to immediate processing, and that is one reason the brand lands where it does in this comparison. Other brands’ withdrawal times are within the same general band and not separately stated.

Loyalty and existing-customer offers. Coral’s free daily Reward Shaker, BoyleSports’ Acca Loyalty, Spreadex’s Acca Boosts, Unibet’s daily Uniboosts and William Hill’s Football Acca Boost sit on top of the welcome offer and are the second lever each operator pulls. Coral’s offer is a daily free-to-play shake that pays out free bets or bonus spins; BoyleSports’ Acca Loyalty demands a £5 stake, 5+ legs, combined odds of 3/1 and pays a free bet; Spreadex’s Acca Boost pays a cash boost from 5% to 100% on football accas; Unibet’s Uniboosts run daily on selected markets; William Hill’s Football Acca Boost runs from 3% on a double up to 200% on 20+ legs with a maximum boost of £10,000 per bet, and is the largest percentage bonus in this comparison. None of these is a welcome offer and none is the headline. Each is what the same bookmaker does for the same customer once the welcome offer has cleared.

Promotion and terms — what’s pinned in the small print

The 10x cap and the mixed-product ban were not the only changes the Commission brought in. The Commission’s marketing code continues to require that bonus terms be presented in a way the customer can reasonably read; operators have rewritten the small print in their welcome-offers pages to bring bonus terms forward of qualifying conditions. The order is the same across the brands reviewed: headlined offer, qualifying conditions, bonus terms (minimum odds, expiry, market restrictions), then the responsible-gambling footer. That ordering is itself part of the new code.

Whistle-to-whistle is the name for the industry’s code on TV advertising: since 1 August 2019, betting advertisements are not shown on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed. Horse and greyhound racing are excluded from the watershed. The code is an industry agreement, not a statute, and the Commission has not made it a licence condition.

The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts takes effect from the 2026/27 season; sleeves and pitchside hoardings remain. This is a voluntary agreement between clubs and the betting industry, not law. It does not change the operator’s licence obligations or the offer mechanics the comparison benchmarks.

Advertising in Great Britain is regulated by the ASA, not the Commission, and runs through the CAP Code (non-broadcast) and the BCAP Code (broadcast). The Commission’s LCCP carries the licence-side marketing standards, and the two overlap on issues such as the appeals-to-under-18s rules and the 25-year-old featured-gambler threshold. The CAP Code rule affects who may appear in an advertisement (over 25, or appearing under 25 but not primarily as a gambler) and not who may bet.

Operators’ responsibility for affiliate marketing is a licence condition: the operator is on the hook for the marketing its affiliates run, including price-comparison sites and review sites. That is part of why an article like this one names and benchmarks operators rather than referring readers to a third party. The price-comparison affiliate is a marketing channel for the bookmaker; the bookmaker is responsible for what the channel says.

Tax and what the bettor pays

Betting winnings in Great Britain are not taxed at the customer level. The customer keeps the entire return on a winning bet, free of income tax. A professional gambler whose betting activity counts as a trade should ask HMRC or an adviser; this page is general information, not tax advice.

General Betting Duty is the operator’s tax on gross profits from betting, currently 15%. From 1 April 2027 a new remote betting rate of 25% applies within General Betting Duty, on remote bets placed with a GB-licensed bookmaker; bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. The HM Government policy paper of 26 November 2025 is the published source. Until 1 April 2027 the remote rate stays at 15% and the existing duty structure holds.

The duty is the operator’s, not the customer’s, and whether operators pass duty on through odds is not established. Spread betting carries its own rates — 3% on financial spread betting, 10% on other spread betting — and is treated separately from fixed-odds betting for duty purposes. Spreadex is the only operator in this comparison that runs spread betting alongside fixed-odds betting, and is regulated by the FCA for the financial side and by the Commission for the fixed-odds side. Spread betting losses can exceed the deposit; the FCA’s regulation does not turn that into a customer-protection regime the Commission’s licence carries.

The Commission’s statutory levy is a separate charge paid by licensees to fund research, education and treatment of gambling harm. It is not General Betting Duty and not a tax.

The offshore question — what unlicensed play loses

A GB licence is compulsory at the point of consumption. The Gambling (Licensing and Advertising) Act 2014 made it an offence for an operator whose remote facilities are used in Great Britain to take bets without a Commission licence, regardless of where the operator is based: the offence sits in section 33 of the Gambling Act 2005 as amended. Sections 33 and 36 are the relevant sections. A Curaçao, Maltese or Gibraltar licence does not authorise a brand to take bets from a customer in Great Britain unless the Commission has also issued a remote licence at the same operator level.

The risk is the operator’s. On summary conviction the section 33 offence carries up to 51 weeks’ imprisonment, a fine up to level 5, or both; six months in Scotland. The Commission has not prosecuted a customer for placing a bet on an unlicensed site, and no offence aimed at a customer was found in the published material. The customer consequence is loss of protection — no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, not bound by the 10x bonus cap, not bound by the £150 vulnerability check.

Enforcement is not blocking. The Commission’s tools are cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and court-order DNS blocking powers that the Commission has been given or is about to receive. ISP blocking is not in operation as of writing. A customer who reaches an unlicensed site can still place a bet on it; the loss is what the licence has bought.

Honest framing. Licensed = identity check, deposit limits, GAMSTOP, 10x bonus cap, £150 vulnerability check, Commission complaints, British redress. Unlicensed = none of those protections, possible loss of funds, no recourse if the operator refuses to pay out. Neither is “the safe choice” by default — the licensed route is the one that adds the protections and the obligations, and the unlicensed route is the one that adds neither.

The brand set in this comparison is licensed. No unlicensed operator is named here.

Standards and currencies of these offers

A few conventions the comparison follows, because they govern how the numbers above have to be read:

• Odds are stated in fractional form (5/1, 11/4, evens) and decimal form (6.00, 3.75, 2.00). A price of evens in fractions is 2.00 in decimals. Fractions under evens (1/2, 1/5) are odds-on — the favourite. The conversion a/b → a ÷ b + 1 holds in both directions.
• Stake and return are stated in pounds sterling. A return is stake plus profit on a winning bet. A free bet’s stake is not usually paid back with the winnings, and a free bet’s winnings are the only transferable amount.
• Each-way is two bets of equal stake on the same selection: one for the win, one for the place. The stake doubles at the moment the bet is placed. Place terms vary by race and by operator.
• Accumulators multiply the odds of each leg into one price. A treble at 2/1, 3/1 and 4/1 carries combined odds of (3 × 4 × 5) − 1 = 59/1; the stake returns only on a winning four-leg acca, and the margin of each leg compounds into the acca’s effective margin.
• Best Odds Guaranteed (BOG) is the operator’s commitment to pay the starting price or the taken price, whichever is higher, on horse racing bets placed before the race. The mechanism is industry standard on UK horse racing.
• Cash Out settles a bet before the event has finished, at a price the operator sets. Cash Out availability is not guaranteed (DAZN Bet’s published terms state that bets stand if Cash Out is unavailable), and the price the operator sets carries its own margin.
• Bet Builder / Same-game multi combines markets from one event into a single bet. The prices compound the margin of each leg and the resulting bet carries a higher effective margin than its individual legs.

What it costs to clear — the calculation

The cost of clearing a bonus appears as a band of expected values, which reflects the different bookmaker margins on the markets a bettor might choose.

A £40 deposit bonus cleared against the new 10x cap demands at most £400 of qualifying bets at the operator’s stated minimum price. On a Premier League football match market at a 5% margin the bookmaker keeps £20 of every £400 wagered by way of expected return; on the same market at a 7% margin the operator keeps £28. On a tennis match at a 4% margin the operator keeps £16. Across lower-margin markets (basketball, baseball, US sports at 4%–5%), the cost drops further; across higher-margin novelty markets or outright winner markets at 7%+ the cost rises.

The clearable amount is not the same as the realised amount. Tokens that expire unused forfeit both stake and the qualifying bets behind them, and the seven-day expiry at most UK bookmakers is the constraint most likely to bind. A bettor who uses all four tokens on a winning acca realises the £40 against the cap; a bettor who lets one expire leaves £10 of the bonus on the table.

The band. Between £16 and £28 of expected loss to clear a £40 bonus on a typical football market, before any expiry. On a tennis match market, between £13 and £20. Across lower-margin US sports markets in season, less. The cap bounds the worst case at roughly 70% of the bonus face value on football; the realised cost on average is below that, and is closer to the lower end of the band when the bettor uses every token on a winning market and avoids higher-margin novelty selections.

None of the operators reviewed here today publishes a deposit bonus that requires wagering at the cap. Where a wagering requirement exists, it is on the bonus cash side of the offer, not on the free bet side, and on the brands above it sits well below the new maximum.

Frequently asked questions

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

Since 19 January 2026, the Gambling Commission’s promotion code caps wagering requirements on betting bonuses at ten times the bonus amount or the amount paid out by a bonus, whichever is higher. A £10 bonus at 50x wagering — £500 of qualifying bets — is no longer permitted; the cap is £100. The cap applies to every operator licensed for remote betting in Great Britain. Whether the cap reaches free bets with no wagering condition is not established in the Commission’s published materials.

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

A minimum odds floor is the lowest price a qualifying bet can carry. Coral, Unibet, Sky Bet and Midnite all set the floor at evens (2.0 decimal, 1/1 in fractions); BoyleSports and Spreadex sit lower, at 1/2 (1.5 decimal). A wagering requirement is the number of times the bonus must be turned over before any winnings can be withdrawn. The two conditions together decide which selections qualify, and how many qualifying bets the bettor has to place before the bonus pays out as cash.

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

A free bet is a token the operator credits against the customer’s account. The token’s stake is the operator’s money; the operator keeps it whether the bet wins or loses. On a winning bet, only the winnings — stake × (odds − 1) — transfer to the customer’s withdrawable balance. The £10 free bet at odds of 5/1 pays out £40 in profit, not £50. The rule is industry standard across the brands reviewed here and is stated in each operator’s own terms.

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

Since 19 January 2026 the Commission’s code bans mixed-product promotions — offers that require a customer to gamble on two or more product types, such as betting plus casino, betting plus bingo, or betting plus lottery. Midnite’s welcome offer, which bundles £25 in free bets with 50 free spins, is the kind of arrangement the new code reaches. Whether the package complies depends on the operator’s opt-in structure, and that is what the operator’s own terms settle.

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, domain or account number; every brand in this comparison is on it. The licence is the operating licence, and the Commission account is the licence number. The register is the test of whether a brand is licensed, and the access date is the date the register was last consulted: October 30, 2026 for this comparison. A licence register lists more brands than any article features; a licence is not a recommendation.

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

Betting winnings are not taxed at the customer level in Great Britain — the customer keeps the full return on a winning bet. General Betting Duty is the operator’s tax, currently 15% of gross profits on betting, with a new remote betting rate of 25% due to apply from 1 April 2027 within the same regime. The customer does not pay General Betting Duty, the spread betting rates (3% financial, 10% other) and the Commission’s statutory levy are the operator’s charges, and a professional gambler whose betting counts as a trade should ask HMRC or an adviser.
