A bookmaker does not give away money. A free bet is a marketing token shaped like currency, and its shape matters more than its face value. The headline figure (£30, £40, £60) is what the operator puts on the advert; what lands in a punter’s pocket is set by smaller terms underneath, and in Great Britain the smallest of those terms now has the Gambling Commission behind it. The promotion rules that took effect on 19 January 2026 cap wagering requirements on bonuses at ten times the bonus amount, and they ban offers that push a customer across product types (betting plus casino, for example). Free bets are not formally covered by the cap where they carry no wagering requirement, but everything around them is now read more carefully than it was a year ago.

The pages below walk that picture from the top down. It starts with the part no advert ever talks about — what the bonus cap changes, and what it does not — then the practical terms every offer shares, the payment and payout mechanics that decide when a win is actually yours, the predictions and bankroll framing that decide whether a free bet is worth staking at all, and the sports the offers attach to. A ten-bookmaker comparison and a legality section round out the picture, with a calculation worked through one free bet at the end.

Responsible gambling: what surrounds the offer

A free bet that asks for nothing back is not a thing the licensed market sells. Even a “free” token comes tied to a deposit, a minimum stake, a minimum price, an expiry window and, on many sites, a verification that asks for photo ID and proof of address before a single penny is risked. The Commission’s identity-check rule, in force since 7 May 2019, applies to bonus claims as well as paid bets, and that is why a sign-up page asks for a passport scan before it asks for a payment method.

The second layer is self-exclusion. Every online operator licensed for Great Britain is part of GAMSTOP, and the Commission made that membership mandatory on 31 March 2020. A punter can bar themselves for six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion rolls forward for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online only — betting shops run their own land-based scheme — and it cuts across every brand in this comparison at once, which is the point of it.

The third layer is money. The Commission brought in a financial vulnerability check on 30 August 2024 (LCCP 3.4.4) and the first phase of it has been live since 28 February 2025. A punter whose deposits minus withdrawals cross £150 over thirty rolling days triggers a public-record search: bankruptcy, county court judgments, the kinds of trace a credit header would pick up. It is not an affordability check, and it is not a pay-slip request; the heavier “financial risk assessments” the press has called affordability checks sit in a separate staged plan (Commission statement of 7 July 2026) with no published start date. Until that date exists, the £150 vulnerability check is the live line. Deposit limits work alongside it: operators must offer a gross deposit ceiling on a fixed time frame, with the first phase live since 31 October 2025 and a second phase currently scheduled for 30 September 2026.

The ceiling itself is the punter’s choice, not the state’s. There is no statutory cap on stakes or losses for sports betting; operators set their own maximums and they can restrict a customer individually. What the law does is mandate the tools — limits, time-outs, self-exclusion — and require the operator to surface them. The customer facing a “£40 in free bets” banner has, before any deposit, the right to set a deposit limit the operator cannot raise without a cooling-off delay.

Help lines sit outside any operator. GamCare runs the National Gambling Helpline; GambleAware funds treatment and research; the NHS runs gambling clinics across England; Gamblers Anonymous runs meetings. None of them sells a bonus and none of them asks for an odds boost.

Bonuses and free bets: how the offer actually works

A free bet is a stake the operator credits to a new account. The stake is yours to place, the winnings are yours to keep, and — on the great majority of UK offers — the stake itself is not paid back alongside the winnings. That single mechanic is the one most punters miss when they read a “£40 in free bets” headline. A £40 free bet at evens (decimal 2.00) returns £40 of profit, not £80. The face value and the realisable value are not the same number, and the gap widens as the odds shorten.

Qualifying for the bonus is a separate transaction. Almost every UK welcome offer demands three things: a real-money deposit, a first bet that is paid in cash, and a minimum price for that bet. The Sky Bet welcome, for instance, is £30 in free bets (three £10 tokens) once the new customer deposits at least £5 and places a first single or each-way bet of at least 5p at 1/1 or greater; Coral’s £40 in free bets is gated on a £20 cash bet at minimum odds of 2.0 (1/1); Unibet’s £40 in free bets runs on the same gate; Betway’s free bets carry their own 1x wagering requirement at minimum odds of 1.75. The minimum-odds rule exists so the operator is not paying a bonus for a punt on something close to a sure thing. Every gate in this list sits somewhere between 1/2 (1.50 decimal) and evens (2.00).

The minimum-odds rule does two jobs at once. On the punter’s side it stops a free bet being “free” — a 1.01 qualifier is paid out by the operator’s own liability, not by the punter’s risk. On the operator’s side it caps the value of the bonus in a way the Commission’s new rules have not yet caught. Until the Commission says otherwise, the lowest legal minimum sits where each operator draws it.

Expiry is the second quiet cost. Sky Bet’s free bets expire 30 days after crediting; Dabble’s expire in 7 days; Unibet’s expire within 7 days of issue; QuinnBet’s are valid for 7 days from credit; BoyleSports’ acca insurance refund expires in 7 days; BetUK’s four £10 free bets are valid for 7 days. A free bet unused is a free bet lost, and most UK tokens die inside a week.

The market rules are the third cost, and they vary more than the headlines suggest. Sky Bet’s tokens are restricted to single or each-way markets and exclude virtuals. QuinnBet allows straight accumulators but not Trixies, Patents or Yankees. Sporting Index ties its tokens to specific product families: fixed-odds free bets on fixed-odds markets, Total Goals free bets on Total Goals markets, Winning Favourites free bets on Winning Favourites markets. BoyleSports pays its acca insurance back as a free bet whose stake is not returned, not as cash. Where the headline says “free bet”, the small print often says “free bet on these markets only, settled as a free bet, expiring on this date”.

Wagering requirements are the line the Commission has just drawn through. A wagering requirement is the multiple of the bonus (or of bonus plus deposit) that must be turned over in qualifying bets before any withdrawal is allowed; “10x wagering” on a £10 bonus means £100 of qualifying bets at the minimum price. Under the rules in force since 19 January 2026 the multiple is capped at 10x for bonuses, and any promotion that bundles two product types — a football bet that unlocks casino free spins, a deposit that opens both a sportsbook and a bingo room — is prohibited. Whether the 10x cap catches a free bet whose terms set no turnover is not established, and most UK welcome offers reviewed here sit below the cap or carry no wagering requirement at all.

There is one last cost the marketing never names: the stake not returned. “Free” in the offer means a credit that places a bet; it does not mean a credit that replaces the stake on a win. A free £10 at 2.00 returns £10 of profit, and a free £10 at 5.00 returns £40. By the same logic a free £10 at 1.50 — the minimum price on many offers — returns £5. The shorter the odds, the smaller the realised value of the token. Picking a long price for a free bet is the only move the punter controls.

Payments and payout speed

Every welcome offer is gated on a deposit, and the deposit method decides whether the offer triggers at all. Coral’s welcome must be qualified with a debit card or instant bank transfer. Unibet’s £40 in free bets is the same: a deposit by debit card or instant bank transfer, no e-wallet shortcut. Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet top-ups, so a Visa credit deposit will be refused and the bonus will not credit. The payment method you choose at sign-up is not just a checkout preference; on many sites it is the difference between a bonus and no bonus.

Once a deposit is made and a real-money bet settles, the bonus credits. On most UK sites the window is minutes to hours for free bets; Sky Bet credits three £10 tokens after the qualifying bet settles; Unibet issues its £40 in free bets within 7 days; the SBK sportsbook (Smarkets) credits £60 in free bets within 48 hours of a £20 first deposit and a £20 qualifying bet at minimum odds of 3.0. The credited token is then bound by its own clock — the 7-day or 30-day expiry on the same page that credits it.

Withdrawal of free-bet winnings is where the punter meets identity verification most directly. The 2019 verification rule applies before the first deposit and again before any payout that the operator has decided to check. Photo ID, proof of address and, at higher spend, source-of-funds questions are normal at this stage; an e-wallet such as PayPal or Revolut Pay can take a payment but does not bypass the document step. LiveScore Bet accepts Visa and Mastercard debit, Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay, and pays through the same channels; Coral adds Google Pay, TrueLayer, Earthport and Trustly to that list. The choice on the cashier page is real for the bonus gate and largely cosmetic for the payout route.

There is no guaranteed payout time at a UK licensed operator in the sense the offshore marketing pages sometimes use. Debit-card withdrawals are usually one to three working days; e-wallets and Open Banking can land the same day once the operator has released the funds; bank transfers through Faster Payments often settle in minutes. None of those speeds is statutorily fixed, and the Commission’s Remote Technical Standards require the operator to hold segregated customer funds but do not impose a clock. Speed is set by the operator’s own cashier.

Identity checks slow the first payout in particular. A punter whose first withdrawal arrives inside an hour of a first deposit is being processed by a payments team that already has the documents, and the rest of us wait for the request to clear the verification queue. This is the trade at the heart of the licensed market: fast payouts assume the operator has done the verification work upfront, and the verification work is what makes the licensed market different from the offshore one.

Predictions, bankroll and what a free bet is worth

No system picks winners consistently. Tipsters sell what they call systems, and the only thing consistent about them is what they charge. A punter with a £40 free bet has a £40 marketing token to deploy, and the right question is not “what should I back” but “where does the token earn the most before it expires”.

The frame that decides value is price. A free bet pays the gross return minus the stake; at decimal odds *d* on a £10 free bet the realised profit is £10 × (*d* − 1). The longer the price, the larger that profit, before any payout share is taken into account. A market that pays 95 pence of every pound staked — a typical overround of 5% — eats 5% of the profit on the way through, so the realised profit is closer to 95% of the raw figure.

A worked example sits below the comparison table. The point of doing it in numbers is that the answer depends on the odds chosen: at 1.90 / 1.90 (fractional 9/10) the realised value is well under the £40 face, and at longer prices the realised value climbs. There is no “correct” odds for a free bet, only the trade between a price the market will take and a price that earns the token enough to be worth the qualification effort.

A second frame is bankroll. Most UK welcome offers expire inside seven days; a punter who plans to deposit, qualify, receive the free bet and place it inside that window has to clear the deposit, the verification step, the qualifying bet and the token expiry in a single working week. A punter who splits that work across two accounts loses the second bonus to expiry. Bankroll framing is the boring part of free bets and the part most often missed.

A third frame is the qualification cost. A £5 qualifying bet at 1/1 or greater costs £5 of real money for a £30 free-bet credit on Sky Bet; the realised value of the £30 is whatever the token wins. If the realised value is lower than £5, the bonus is a loss; if higher, the bonus is a gain. The qualification bet is the cost of entry, and its cost is the same whether the bonus is claimed or not.

A fourth frame is the commission hidden in the price. Two outcomes at 1.90 each give a payout share of 1 ÷ (1/1.90 + 1/1.90) = 0.95, or 95%, and a margin of 5%. A free bet paid at the same 1.90 earns roughly 95% of the raw figure. The punter who picks a market with a 3% margin instead of a 5% margin keeps a little more of the token’s value. None of this is prediction; it is arithmetic the punter can do before placing the bet.

Sports and tournaments: what the free bet attaches to

A free bet in Great Britain is rarely tied to one sport. Sky Bet’s tokens work on single or each-way markets excluding virtuals, and Sky Bet’s sports book covers football, horse racing, tennis, golf, cricket, darts, rugby, snooker and the major US leagues. Unibet runs the Premier League, Champions League, horse racing (with Best Odds Guaranteed), tennis, UFC, basketball and the same American spread; Coral adds greyhound racing and a deeper in-play book; Betfair carries Bet Builder, a 90 Minute Payout market and free live streams of UK and Irish racing and selected football. The token is not pinned to the sport; the punter pins it.

Horse racing is the sport the offers most often sit on, because it is the sport with the most each-way betting, the most non-runner mechanics, and the most Best Odds Guaranteed promises. Best Odds Guaranteed (BOG) pays the starting price if it is higher than the price taken at bet placement; Unibet, Coral and several others run BOG on UK and Irish racing. A free bet on a horse at a price the starting price beats is a free bet paid out at the better of the two numbers, and the operator wears the difference.

Football is the sport with the most market depth. Premier League, Champions League, La Liga, Serie A, Ligue 1, the Eredivisie, the Bundesliga — every top-licensed UK book covers the same competitions at depth. The bet types are where the books diverge: Bet Builder (same-game multi), Bet Builder+ (combining Bet Builders across games), Both Teams To Score, correct score, total goals over/under, handicaps, corners, cards, player shots. A free bet can be split across any of these and the operator’s only constraint is the minimum price.

The Cheltenham Festival and the Grand National are the two events the welcome offers are timed around. Free Cheltenham bets and free Grand National bets are the seasonal search terms the offer pages are written to catch, and the welcome terms are rarely amended for the festivals. The same token that would have expired in seven days on a routine Tuesday expires in seven days during Cheltenham; the punter who has held a token for the festival uses it on the festival, and the punter who has not, does not.

US sports — NBA, NFL, MLB, NHL — and the majors of golf, tennis and boxing round out the sports book at every operator reviewed here. In-play markets are universal across the licensed set. Esports sit inside the same book on most sites; virtual events (computer-drawn horse and dog races, virtual football) sit on a separate licence category and a separate tab in many cases. The token’s market rules decide which sports it can be spent on; Sky Bet’s “excluding virtuals” rule is a reminder that the licence category and the sports book are not always the same thing.

Ten UK bookmakers compared: licence and free-bet terms

The table below compares the ten bookmakers reviewed on the same three matters: brand and remote licence number, the operating company and Commission account, and the free-bet terms stated on each operator’s own UK terms page. The licence column carries the public-register number and the operating company; the offer column carries the headline free-bet package as the operator’s own terms describe it. Cells where the operator’s own terms do not state a value are left blank, because a guess in a comparison is worse than a gap.

The licence numbers above are the numbers that appear on the Gambling Commission’s public register. The Commission’s register can be searched by business name, trading name, domain or account number and is the whole test of whether a brand holds a licence for Great Britain; a licence number that does not resolve there is not a licence. Several brands run under one licence holder — Betfair and Paddy Power both run under PPB Counterparty Services, for instance, and Ladbrokes and Coral both run under LC International — so a licence is a property of the holder, not the brand. Every brand in this comparison is GAMSTOP-registered, which is a mandatory licence condition for online operators since 31 March 2020.

The offer column is descriptive, not evaluative. A £40 headline is not the same as a £40 realised value; the gap depends on the minimum price, the expiry, the eligible markets and the stake-not-returned rule. The numbers in this column are what each operator’s UK terms page says; the realised value depends on how the punter uses the token.

What new customer free bets are: the core picture

A new customer free bet is a marketing credit a UK licensed bookmaker pays to a freshly verified account holder in exchange for a real-money deposit and a qualifying bet at a stated minimum price. The credit can be used to place a bet; the stake is taken from the credit; the winnings, where the bet wins, are paid back as cash or as a further free bet, depending on the operator’s terms; the stake of the free bet is, on the great majority of UK offers, not paid back alongside the winnings. The credit expires on a stated date, and is restricted to a stated set of markets. The whole package is non-withdrawable.

The honest way to think about the headline figure is as a ceiling. The £40 Unibet advertises is the most the punter will ever realise from the token, and only if the punter picks a price the market will give them; the realised figure is usually below £40, sometimes well below, and only zero if the punter fails to place the token inside the expiry window. The arithmetic of one worked example sits at the foot of this page.

The cap on bonus wagering at 10x, in force since 19 January 2026, has changed the ceiling inside which welcome offers can be set. A bonus that asked for 50x turnover on a £10 deposit — a figure that was common in the casino market — is no longer permitted at a Commission-licensed sportsbook. Free bets that carry no wagering requirement sit outside the cap, for now; the Commission has not said the cap catches them, and it has not said it does not. The next twelve months are likely to settle that question one way or the other, and welcome-offer pages are likely to look different by the end of 2026 as a result.

Beneath the headline, three costs do not change: the stake not returned, the expiry clock, and the minimum price on the qualifying bet. The first is a property of how free bets are settled; the second is a property of the operator’s own terms; the third is a property of the operator’s own gate. None of the three is set by the Commission, and none is going away.

UK legality and regulation: the frame around the offer

The Gambling Commission licenses the whole commercial market in Great Britain under the Gambling Act 2005, which covers England, Scotland and Wales; Northern Ireland sits outside the Act and runs its own older regime, so a “GB licence” is precisely a Great Britain licence and not a United Kingdom 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 incorporated — sections 33 and 36 of the 2005 Act as amended — and a Curaçao, Maltese or Gibraltar licence is not a substitute. Several licence categories cover the market: remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting, and remote betting intermediary (the licence that runs the betting exchanges). The brands in this comparison all hold a remote general betting standard (real events) licence.

The Commission’s public register can be searched by business name, trading name, domain or account number and is the test of whether a brand holds a licence for Great Britain. A licence number that does not resolve on the register is not a licence; a brand that uses .co.uk is not licensed by virtue of the domain, and a brand that uses .com is not unlicensed by virtue of the domain. Financial spread betting is regulated by the Financial Conduct Authority, not the Commission — Spreadex, for instance, holds both an FCA registration for spread betting and a Commission Gambling Commission licence for fixed-odds betting — and a punter who strays across that line is in a different regulatory regime.

Identity verification has been required since 7 May 2019 before the first deposit and before the first bet, including with a free bet or bonus claim. Photo ID, proof of address and (at higher spend) source-of-funds questions are normal at this stage; an e-wallet cannot bypass the document check, because the operator still has to satisfy the money-laundering rules. No GB-licensed operator accepts an anonymous deposit or an anonymous bet.

Advertising is licensed separately from gambling. The Commission licenses the operator; the ASA, under the CAP Code (non-broadcast) and BCAP Code (broadcast), regulates the marketing. CAP Code section 16 sets the test for social responsibility: no marketing of strong appeal to under-18s, and no one who is or appears to be under 25 may be featured gambling or play a significant role in the advertisement, with an exception for marketing that is placed where a bet can be made directly. “Whistle-to-whistle” — no betting advertisements on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed, horse and greyhound racing excluded — has been in place since 1 August 2019 as an industry code rather than as statute.

The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts from the 2026/27 season onward is voluntary, not law. Sleeve and perimeter-hoarding sponsorships remain. The Commission’s own powers are operator-facing: cease-and-desist notices, search-engine referrals, registrar and host coordination, payment-provider work, and court-order DNS blocking powers that have been given or are about to be given to the Commission. ISP-level blocking is not in operation as a general measure.

The player pays no tax on betting winnings in Great Britain; that is general information and is not tax advice, and a professional gambler should ask HMRC or an adviser. General Betting Duty, the operator’s tax on gross profits, currently sits at 15% across the board, with a new remote rate of 25% taking effect from 1 April 2027 on remote bets outside the protected categories (UK horse racing, self-service betting terminals in licensed premises, pool betting, in-person betting) which stay at 15%; spread betting has its own rates (3% financial, 10% other). Until 1 April 2027 the remote rate stays at 15%. Whether operators pass duty on through the odds is not established.

Offshore remains a separate frame. A GB-licensed operator offers verification before the first bet, GAMSTOP coverage, the Commission’s complaints route, ADR through an approved body, the 10x bonus cap, and the £150 vulnerability check; an offshore operator offers none of those protections and exposes the punter to the loss of funds if the operator decides not to pay. Both are reachable from a British IP address; only one of them is licensed 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 2005 Act, aimed at the operator; the Commission has not established an offence aimed at the customer who merely bets on an unlicensed site, but the loss of protection is the relevant fact.

Operators: what each brand is worth

Sky Bet — £30 in free bets, longest expiry on the list

Sky Bet’s welcome package is the one with the longest clock. The £30 in free bets is split into three £10 tokens after a £5+ deposit and a 5p+ first single or each-way bet at minimum odds of 1/1; the tokens expire 30 days after crediting, which is four times the 7-day window that dominates the rest of the comparison. The credit can be spent on single or each-way markets only — virtuals are excluded — and the stake is not returned with winnings.

The 30-day clock is the operator’s most generous term on this list and the one that suits a punter who has not yet decided which race or match to use the token on. The 1/1 minimum on the qualifying bet is also middling rather than steep, which keeps the qualification cost low. The single-or-each-way restriction is the trade: a token that works on a Lucky 15 or a Heinz on most other books works only on singles and each-ways here. For a punter who bets singles and each-ways on horse racing, Sky Bet’s package is the most accommodating on the list. For a punter who wants to spend the token on a long-odds football acca, it is the wrong gate.

Copybet — Acca Booster and Daily Profit Boost on every acca

Copybet’s product line is built around the accumulator. The Acca Booster pays up to a 100% cash bonus on accas of at least three selections, and a Daily Profit Boost pays up to 15%. A welcome offer that pays in cash on a winning acca — rather than as a free bet whose stake is not returned — is a different product from the rest of this list, where most tokens are settled as free bets.

The punter this suits is the one who was going to place an acca anyway. The punter it does not suit is the one whose betting pattern is singles and each-ways; for them the bonus is irrelevant and the daily book is the test. Copybet’s sports book covers the standard British fare, and the rest of the offer set (Bet Builder, in-play, free-to-play games) is on the operator’s own terms.

Betfair — Bet Builder, 90 Minute Payout, free racing streams

Betfair Sportsbook is the fixed-odds side of a brand whose exchange operation sits on a separate betting intermediary licence. The product line is the deepest in-play book on this list: Bet Builder, free live streaming of UK and Irish horse racing and football within the app, a 90 Minute Payout market that settles on the result at the 90-minute mark rather than after stoppage time. The 90-minute market is the offer that suits a punter who has a strong view on a football result but not on the chaos of injury-time goals.

The welcome offer is not the headline here. Betfair’s value is the product depth: the live streams, the in-play markets, the Bet Builder, and the exchange underneath. The punter who wants the exchange and the sportsbook under one account gets it; the punter who only wants the welcome bonus gets a smaller headline than the others on this list. For the in-play punter, Betfair is the strongest product on the list by a margin the welcome bonus cannot match.

Geoff Banks — ante-post and live in-play prices, no welcome bonus

Geoff Banks sits on the app published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. Ante-post is the long-odds market on a horse racing or sporting event weeks or months ahead of the running; the operator’s edge is a depth of ante-post markets that the larger books sometimes thin out.

There is no welcome offer on this brand, which puts it at the bottom of any headline comparison. The punter it suits is the one who bets ante-post and wants a book that has not pulled its future markets; the punter it does not suit is anyone looking for a free-bet credit at sign-up. Geoff Banks is the long tail of this list, and the value is in the markets rather than in the bonus.

Unibet — £40 in free bets, 7-day expiry, debit card only

Unibet’s welcome is the £40 in free bets package paid against a £20 sports bet at minimum odds of 2.0 (1/1), with the free bets issued within 7 days and expiring 7 days after issue, for new GB customers using a debit card or instant bank transfer. The product line behind the bonus is the largest on this list: 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 1/1 minimum on the qualifying bet is the mid-range gate that keeps the qualification cost reasonable without opening the bonus to 1.01 bets. The 7-day expiry is the standard British window. The debit-card-only rule on the bonus is the real friction: a punter who has set up a PayPal deposit cannot claim this offer. For the punter who pays by debit card and wants a deep in-play book with BOG and Uniboosts, Unibet is one of the strongest offers in the comparison. For the punter who pays by e-wallet, it is unreachable.

Sporting Index — mixed free-bet package across fixed odds and spread betting

Sporting Index’s welcome is the most structured on this list. A £10 fixed-odds bet at minimum odds of 1/2 unlocks three £10 fixed-odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets, and a £1 Race Index spread bet; the qualifying bet cannot be placed in play or cashed out early. The bonus is paid in seven tokens across two product families, fixed odds and spread betting.

Spread betting is the product Sporting Index is built around, and the bonus reflects that. A punter who has never spread-bet will find the Total Goals, Winning Favourites and Race Index markets unfamiliar; the realised value of the spread-bet tokens depends on the spread settling close to the line the punter chose, which is a different calculation from a fixed-odds win. The 1/2 minimum on the qualifying fixed-odds bet is the lowest in this comparison. The no-in-play, no-cash-out rule on the qualifier is a reminder that the operator wants the qualifying bet to be a clean fixed-odds bet, not a position the punter can trade out of. For a punter who already spread-bets, the package is rich; for a fixed-odds-only punter, three of the seven tokens are notional.

BetUK — four £10 free bets, two of them acca-locked

BetUK’s welcome pays four £10 free bets after a £10+ deposit and a sports bet within 7 days of registering: two football accumulators of 4+ selections and two multiples of 2+, with the four tokens valid for 7 days and opt-in required. The token split is the headline here — half the bonus is locked to a 4-leg football acca, the other half to a 2-leg multiple.

The punter this suits is one whose betting pattern is football accas. The punter it does not suit is one whose pattern is singles or horse racing, for whom two of the four tokens cannot be spent on the markets they want. The 7-day expiry is standard. The deposit floor is £10. The opt-in requirement is a reminder that the bonus is not automatic and that the punter has to tick the box on the offer page before placing the qualifying bet. For the football acca punter, the package is well-fitted; for anyone else, it is partial.

10bet — 100% betting bonus up to £50 with daily free bets and free spins

10bet’s welcome is a 100% match bonus up to £50, plus daily free bets and free spins advertised in the app. The structure is the casino-style match bonus rather than the sportsbook-style free-bet credit, which means the wagering requirement and the eligible markets are the operator’s own terms and the Commission’s 10x cap now applies. The cap is a ceiling on the wagering multiple, not a ceiling on the size of the bonus.

The match-bonus shape suits a punter who wants to deposit and play through rather than deposit and free-bet. The punter it does not suit is one who wants a fixed-odds-only token with no wagering. For a punter who reads the wagering terms carefully, 10bet is the deepest bonus on the list; for a punter who does not, it is a deposit match with strings attached.

Dabble — £10 for £10, 7-day expiry, stake not returned

Dabble’s welcome is the simplest on this list: a £10 free bet for a £10 qualifying deposit and bet for new customers, with minimum odds applying, a 7-day expiry and the stake not returned. The 1:1 face value is the cleanest structure on this page; there is no 4-leg acca lock, no spread-bet token, no 100% match.

The punter this suits is one who wants the qualification cost and the realised value to be the same number on a single token. The 7-day expiry is the standard window. The minimum odds apply but are not published in the offer headline; the operator’s own terms are the source. For the punter who wants a clean, single, stake-not-returned token, Dabble is the simplest offer on this list.

LiveScore Bet — deep cashier, modest bonus

LiveScore Bet’s value sits on the payment side: Visa and Mastercard debit, Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. The welcome bonus is the operator’s standard offer; the product line is the standard British sports book. The punter this suits is one whose payment-method constraint is the deciding factor — a punter who wants Apple Pay and Open Banking will not get them at every book on this list, and LiveScore Bet’s set is the broadest.

The trade-off is that the bonus is not the deepest on the list. The punter chasing a headline figure will find a bigger number elsewhere. The punter whose payment-method constraint is real — the Open Banking punter, the Revolut punter, the Apple Pay punter — finds LiveScore Bet the most accommodating on the cashier page.

A free-bet value worked through

The arithmetic of one free bet, using the terms the operators in this comparison state and an illustrative two-way market priced at decimal odds of 1.90 / 1.90 (fractional 9/10). The calculation is a statistical estimate — the average over many such bets, not a guaranteed outcome for any single punt.

For a free bet whose stake is not returned, the realised value at odds *d* is the free-bet amount × (*d* − 1) ÷ *d*, scaled by the payout share of the market. On a £10 free bet at 1.90 on a market with a 95% payout share (a 5% overround on a two-way line), the raw profit is £10 × (1.90 − 1) = £9, the realised value before the market margin is £9 × 0.95 = £8.55. The figure sits as a band rather than a single number, because the realised value moves with the price chosen: at 1.50 (1/2), the raw profit is £5 and the realised value is roughly £4.75; at 3.00 (2/1), the raw profit is £20 and the realised value is roughly £19.

A £40 free bet at the same 1.90 / 1.90 example multiplies the same percentage through: raw profit £36, realised value roughly £34.20. The face value and the realised value are not the same number, and the gap widens as the price shortens. At 1.20, the raw profit on a £40 free bet is £8 and the realised value is around £7.60; the same token at 10.00 returns £360 raw and around £342 realised. The longer the price, the larger the realised value.

The worked figure is an average. A single bet pays the full raw profit at the price taken; the market margin averages out across many bets. The punter who uses the token once realises whatever that one bet pays; the punter who treats the realised value as a budget for a series of bets on different events will, on average, land near the figure above. That is what the realised value means and the ceiling it applies to.

Frequently asked questions

What is a free bet?

A free bet is a marketing credit a UK licensed bookmaker pays to a new or existing customer, usually in exchange for a qualifying real-money bet, which can be used to place a stake without using the customer’s own cash. The winnings, where the bet wins, are paid back to the customer; on the great majority of UK offers the stake of the free bet is not paid back alongside the winnings, so a £10 free bet at even money (decimal 2.00) returns £10 of profit and not £20. The credit is non-withdrawable, is restricted to a stated set of markets and expires on a stated date set by the operator’s own terms.

How does a free bet work in practice?

A new customer signs up, completes the operator’s identity verification (photo ID and proof of address), deposits a stated minimum, places a qualifying bet at a stated minimum price, and receives the free-bet credit after the qualifying bet settles. The credit is then spent on a market the operator’s terms allow; the winnings, where the bet wins, are paid back as cash or as a further free bet depending on the offer; any stake is not returned. The whole sequence is governed by the operator’s own terms page, which is the binding document on minimum price, eligible markets, expiry, settlement currency and whether the stake is returned.

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 wagering requirements on bonuses at 10x. A £10 bonus at 50x wagering would have required £500 of qualifying bets at the minimum price; under the cap no more than £100 of qualifying bets can be required for a £10 bonus. The same rules ban mixed-product promotions — offers that bundle two product types, such as a sports bet that unlocks casino free spins. Whether the 10x cap catches free bets that carry no wagering requirement is not established in the published rules, and most UK sportsbook welcome offers reviewed here sit below the cap or carry no wagering at all.

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

Minimum odds are the shortest price the operator accepts on the qualifying bet that triggers the bonus; a 1/1 (decimal 2.00) minimum means the qualifying bet must be priced at evens or longer, and a 1/2 (decimal 1.50) minimum means the qualifying bet can be priced at half-evens or longer. The minimum-odds rule exists so the operator is not paying a bonus for a near-certain bet. The wagering requirement is the multiple of the bonus (or of bonus plus deposit) that must be turned over in qualifying bets before any withdrawal; a 10x wagering requirement on a £10 bonus means £100 of qualifying bets at the minimum price. Under the Commission’s rules in force since 19 January 2026, no bonus can carry more than 10x wagering.

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

A free bet settles on the gross return minus the stake, because the credit is treated as a marketing token rather than as a cash stake. A £10 free bet at evens (decimal 2.00) returns £10 of profit and not £20, because the operator has not paid the £10 stake on the customer’s behalf in the first place. The stake-not-returned mechanic is what gives a free bet its realised value — the headline figure on the advert is the ceiling, and the actual payout is the profit at the price taken. A few operators do return the stake on selected markets; the operator’s own terms are the binding document on whether the stake is returned.
