A sign-up offer looks like a welcome mat. Step through the door and the betting site hands you £20, £40, sometimes more, in free bets. The mat covers a floor that has its own rules: minimum odds, expiry windows, qualifying bets settled before the free bet credits, and a stake that the bank keeps when you win. A reader who reads the headline alone loses track of those rules in the first week. This page is the read-through — what the offer really costs, which bookmaker is it and which one of the ten reviewed here suits the way you actually bet.

Data current as of 27 October 2026, checked against the Gambling Commission’s public register and each operator’s own published terms. Specific odds and margins are not quoted from any operator here; the figures cited are examples chosen to illustrate the calculation, not live prices.

Responsible gambling comes before the offer

Every bookmaker in this guide holds a remote licence from the Gambling Commission and participates in GAMSTOP, the national multi-operator online self-exclusion scheme. That means two things for the reader before a single offer is examined.

First, identity is verified before the first deposit. Name, address and date of birth have been checked since 7 May 2019 — the check happens before you can deposit, place a bet or use a free bet. No anonymous play at a licensed site.

Second, GAMSTOP lets a customer self-exclude across every licensed online operator at once for six months, one year, five years, or five years with auto-renewal. After the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps, not betting shops, which use a separate service. Anyone who feels their betting is drifting should register with GAMSTOP before opening another account.

Two further safeguards sit alongside GAMSTOP. A financial vulnerability check, in force since 30 August 2024, applies to licensed remote betting when a customer’s deposits minus withdrawals cross £150 in a rolling 30 days (since 28 February 2025); the check looks at public records such as bankruptcy or county court judgments, not income or credit history. Financial risk assessments — the affordability checks discussed in the press — were announced in a staged plan on 7 July 2026 with no start date. Deposit limits have applied to a first phase since 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is live is not established. There is no state-set deposit ceiling: any limit on what a customer stakes is the customer’s own choice.

Help is available through GamCare and its National Gambling Helpline, through GambleAware, through NHS gambling clinics, and through Gamblers Anonymous. The first step if a bet stops being entertainment is one of those services — not a bigger free bet.

What a sign-up offer actually is

A sign-up offer is the headline a bookmaker runs to win a new account. Three shapes cover almost everything the market shows in 2026.

The first is the free bet. The bookmaker credits your account with a stake that is not your own money, and you use it on a market. When the bet wins, the bookmaker pays the winnings — the profit at the stated odds — and keeps the free-bet stake. A £10 free bet at decimal odds of 2.00 returns £10 in profit, not £20, because the £10 stake is not paid back. The free bet usually carries an expiry, a minimum price for the market it can be used on, and a list of markets it cannot be used on. A free bet is the most common shape on UK sportsbooks today, and it is the shape every reviewed operator in this guide runs.

The second is the matched free bet. You deposit and bet your own money, and the bookmaker credits a free bet of a similar size. Coral’s sports welcome offer — “Get £40 in Free Bets when you bet £20” — is the canonical form: deposit and stake £20 at minimum odds of 2.0 (1/1), the £40 of free bets lands within seven days and expires seven days after issue. Unibet’s sports welcome offer uses the same headline. Both are matched.

The third is the bonus, paid as cash or as bonus funds that must be turned over a set number of times before withdrawal. This shape is less common on UK sportsbooks than the free bet because bonus wagering requirements are capped at 10x under the Gambling Commission’s updated promotion standards introduced on 19 January 2026. A £10 bonus at 50x wagering would have meant £500 of bets before withdrawal; under the cap no more than £100 can be required.

Mixed-product promotions — an offer that ties betting to casino, bingo or lottery play, such as “stake £10 on football for free spins” — are banned under the same rules. Whether the 10x cap applies to free bets that carry no wagering condition is not established: a free bet with a 7-day expiry and no turnover requirement is a different beast from a bonus that must be turned over before withdrawal. The honest reading of the rules is that a free bet with no turnover condition sits outside the cap, while a bonus that asks the customer to gamble the bonus amount any number of times before withdrawing winnings sits inside it.

Two words on the marketing deserve a quiet call-out.

“Risk-free” is not what it sounds like. A stake-back offer refunds the losing stake as a free bet when the qualifying bet loses — Hollywoodbets’ sports welcome offer works this way, refunding the stake of a losing accumulator as a free bet up to £30. The refund is a free bet, not money: the stake is not paid back with a win, and the free bet carries its own expiry. The original stake was always at risk; only the refund side is fee-free.

“Free” is the same word from the other angle. The stake is never free in a free bet: when the bet wins, the bookmaker keeps the stake and pays the profit. The free-bet value calculation shows how that arithmetic lands in real money.

How the offers compare on the terms that matter

The table below covers every reviewed operator on the same four columns: the brand, its Gambling Commission remote licence number and licence holder, and what the operator’s own terms state on this page’s subject — the headline welcome offer, where one is published, and the headline constraint that follows from it (a minimum deposit, a minimum price for the qualifying bet, a wagering factor, an expiry).

The columns are the matters a reader compares when picking among these offers. Cells carry only what the operator’s terms state; where the terms do not name a figure, the cell is left blank, not approximated.

Two patterns run through the table. Most operators frame the offer as “Bet £X, Get £Y in Free Bets”, with X and Y chosen so Y is larger than X — a £10 bet for £10 in free bets, a £20 bet for £40 in free bets, a £10 bet for £60 in free bets at Smarkets’ SBK sportsbook. The bigger the Y, the steeper the qualifier: Smarkets’ offer requires a £20 bet at minimum odds of 3.0, while Coral’s £40 offer is unlocked at minimum odds of 2.0 (1/1). A reader who wants the bigger headline pays for it in qualifying-bet risk.

The second pattern is the qualifying price. Minimum odds of 1/2 (1.50) appear across several offers; minimum odds of 2.0 (1/1) appear on Coral, Unibet and the £40 Betway offer; minimum odds of 3.0 appear on Smarkets’ SBK. The higher the floor, the narrower the menu of qualifying markets — and the more the offer rewards a customer who already bets at those prices. A reader whose normal qualifying bet is at 1.70 should not chase an offer whose qualifier is 3.0: they will either lay a market they would not normally play, or fail to qualify.

What a free bet is worth in real money

A free bet at face value is what the operator credits to your account. A £10 free bet is worth £10. The honest question is what it is worth when the bet wins and the stake is not paid back. The answer is the free-bet value, calculated as the free-bet amount multiplied by (odds minus 1), divided by the odds, multiplied by the payout share of the market.

Take the Sky Bet terms as a worked shape: a free bet is credited on a qualifying settlement, expires 30 days after crediting, can be used only on single or each-way markets (not multiples, not virtuals), is non-withdrawable and does not return the stake with winnings. Other operators carry similar restrictions. Dabble’s welcome offer expires free bets in 7 days; QuinnBet’s free bets are valid for 7 days from credit on any market at minimum odds of 1/2 (1.5) and maximum odds of 50/1, with straight accumulators allowed but Trixies, Patents and Yankees excluded. The expiry window and the market list are part of the offer’s shape.

For a free bet of £10 at decimal odds of 1.90 (a typical football match price), with an even two-way market as the illustrative example — one outcome at 1.90, the other at 1.90 — the payout share is 1 ÷ (1/1.90 + 1/1.90) = 0.95, and the margin is 5%. The free bet’s expected value is £10 × (1.90 − 1) ÷ 1.90 × 0.95, which comes to £10 × 0.474 × 0.95 ≈ £4.50. A £10 free bet at the same price on a tighter market — say one outcome at 1.85, the other at 1.85 — carries a payout share of about 0.927 and a margin of about 7.3%, and the free bet’s expected value falls to roughly £4.05. The result is a band, not a single number: roughly £4.00 to £4.50 for a £10 free bet at decimal odds near 1.90, with the wider end for the tighter market and the narrower end for a market with a larger bookmaker margin. The band is the offer’s expected value to the bettor before any minimum-odds restriction or expiry pressure is taken into account.

This is a statistical estimate, an average over many bets under the stated assumptions, not a guaranteed outcome for any single free bet. A reader using the free bet on a single short-priced favourite lands closer to the higher end; a reader who lays it on a long outsider accepts a low probability of winning in exchange for a larger payout when it does.

The stake of the free bet is not paid back with the winnings, and that single rule is what makes the expected value lower than the headline implies. A £10 free bet is not a £10 cash bet. A £10 cash bet at 1.90 returns £19, of which £9 is profit; the same selection funded with a £10 free bet returns £9 in profit because the £10 stake is the bookmaker’s, not yours. The arithmetic is the difference between an offer’s face value and what it is worth in the hand.

The same arithmetic turns on a single input: the market’s payout share. A free bet used on a heavily margined market — a novelty market, an in-play exotic — is worth less than the same free bet on a tight Premier League 1X2. The reader who cares about value uses the free bet where the price is closest to even, and saves cash for the long shots.

The ten reviewed bookmakers, set out and judged

The ranking below follows the order research sets; the verdicts are the page’s own. Each block describes what the operator’s own terms say about the welcome offer and the headline product, and closes on what kind of bettor it suits.

1. Swifty Sports — a feature-led newcomer without a headline welcome offer

Swifty Sports is operated by Swifty Global (UK) Ltd under Gambling Commission remote licence 058957-R-334734-006 (Commission account 58957) for remote general betting standard (real events). The app store listing for the bookmaker names Best Odds Guaranteed, Cash Out on horse racing and football, daily price boosts, live streaming and in-play betting; Bet Builder is listed as coming soon, and the listing itself is the source for these features.

The App Store listing does not name a headline welcome offer, which is the single most notable fact about Swifty Sports as a destination for a reader looking for a sign-up incentive. The reader who chooses Swifty Sports is choosing the feature set — best odds guaranteed on horse racing, a daily price boost, in-play — over a headline free bet. There is no arithmetic to compute on a free-bet value because there is no free bet to value.

Verdict: an ideal platform for the racing and football punter seeking BOG, Cash Out, and in-play streaming from a regulated source; less suitable for the reader prioritizing a welcome sign-up bonus.

2. BetGoodwin — three small free bets for a small qualifying bet

BetGoodwin is operated by Goodwin Racing Limited under Gambling Commission remote licence 002927-R-327985-008 (Commission account 2927) for remote general betting standard (real events). The sports welcome offer is “Bet £10 & Get £15 in Free Bets”, broken into a £5 sports bet, a £5 acca and a £5 Sub-Cover bet.

The split matters. The £5 acca and the £5 Sub-Cover bet each come with their own market restrictions — an acca free bet is unusable on a single, a Sub-Cover free bet is bound to the Sub-Cover market — so a reader who treats the £15 as one block of free bets is reading the offer wrong. The qualifying bet is a single £10, and £15 returns in three pieces is a clean 50% uplift on the qualifying stake.

Verdict: a clean fit for the reader who places a single qualifying bet of £10 and uses each free bet in its named market; the split earns the qualifying bet a higher headline percentage than Coral’s £40-for-£20, but the smaller headline is offset by fewer restrictions on the form of the qualifying bet.

3. Betboro — a matched free bet with a multi-leg qualifier

Betboro is operated by Webmedia Development N.V. under Gambling Commission remote licence 044181-R-324363-007 (Commission account 44181) for remote general betting standard (real events). The sports welcome offer is a 100% matched free bet up to £25 on the first qualifying wager; a debit card deposit of £10 or more is required, with a first bet of £5 to £25 carrying at least three selections each at decimal odds of 1.60 (3/5) or higher.

The qualifier is a multi-leg bet at minimum odds of 1.60 per leg. A reader whose normal betting pattern is singles will need to find a three-leg market at the floor price to qualify; the offer is structured around a punter who already bets short-priced multiples.

Verdict: the right match for a reader who already builds three-leg accas at 1.60-plus prices; the wrong match for a singles punter who would have to construct a qualifying bet they would not otherwise play.

4. Coral — a £40 headline on a £20 qualifier, with seven-day windows

Coral is operated by LC International Limited under Gambling Commission remote licence 054743-R-330863-014 (Commission account 54743) for remote general betting standard (real events) and remote betting intermediary. The sports welcome offer is “Get £40 in Free Bets when you bet £20”: deposit and stake £20 at minimum odds of 2.0 (1/1); the £40 in free bets lands within seven days and expires seven days after issue; new GB customers only; debit card or instant bank transfer.

The headline is the largest in this guide’s table that pairs with a £20 qualifier, and the math is straightforward: £40 of free bets on a £20 qualifying stake is 100% extra, before any free-bet value arithmetic. The seven-day windows on issue and expiry are tight: a reader who delays the qualifying bet by a week has burned the offer.

Coral also runs a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games such as Football Super Series with a £10,000 jackpot — recurring value beyond the welcome. Payment options include Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly.

Verdict: the headline-to-qualifier ratio is the most generous in this guide for a reader willing to bet £20 at minimum odds of 2.0, and the seven-day windows mean the offer punishes any delay; the recurring Reward Shaker is a reason to stay beyond the welcome.

5. Geoff Banks — ante-post and in-play, no published welcome offer

Geoff Banks is operated by GB Sports Advisors Limited under Gambling Commission remote licence 054095-R-330366-010 (Commission account 54095) for remote general betting standard (real events). The app is published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. The App Store listing does not name a headline welcome offer.

The Geoff Banks proposition is the form of the markets, not a sign-up credit. Ante-post markets on horse racing, golf and major events, in-play pricing, and a small operator profile — GB Sports Advisors Limited is a long way from the major operators on this list — appeal to a reader who wants a niche bookmaker rather than a free bet.

Verdict: a specialist home for ante-post racing and major event punters who value live pricing over a welcome bonus; those motivated primarily by sign-up incentives will find other operators more suitable.

6. Betway — two overlapping welcome offers and a published 1x wagering requirement

Betway is operated by Betway Limited under Gambling Commission remote licence 039372-R-319367-029 (Commission account 39372) for remote general betting standard (real events). The App Store listing shows a “Bet £10, Get £10 in Free Bets” welcome offer on first deposit, with minimum odds applying and a 7-day free bet expiry, the stake not returned with winnings. A separate welcome offer for new UK and Ireland customers credits £40 in free bet tokens (4 × £10) on settlement of a first bet of £10 or more at minimum odds of 2.0, with a 7-day expiry and debit card deposits only. The minimum deposit is £10 and free bets carry 1x wagering at odds of 1.75 or higher.

Two welcome offers on one licence is unusual and worth a careful read. The £10-for-£10 offer is a clean matched free bet at minimum odds the listing does not pin down; the £40-in-tokens offer is a four-part free bet with a higher minimum price and a 7-day window. The 1x wagering requirement at odds of 1.75 or higher is unusual on a free bet — most free bets on this list carry no wagering at all, and a 1x turnover on the free-bet winnings at 1.75 or higher is a real constraint on how the winnings can be cleared.

Verdict: appropriate for the bettor who values clear turnover terms; the 1x requirement at odds of 1.75 applies to winnings, meaning funds are not immediately withdrawable as cash, which the customer should weigh against the four-token free-bet structure.

7. Smarkets — a betting exchange and a sportsbook under one licence

Smarkets is operated by Smarkets (Malta) Limited under Gambling Commission remote licence 039173-R-319366-011 (Commission account 39173) for remote betting intermediary. The licence covers the Smarkets exchange. The same operator runs the SBK sportsbook, whose 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; the SBK app lists Cash Out, Bet Builder and live horse racing streams.

The £60 headline on a £20 qualifier is the largest in this guide’s table, and the qualifier is the strictest: minimum odds of 3.0 on the qualifying bet is a market most readers do not normally play. A reader chasing the £60 needs to find a market at 3.0 — a clear outsider, a long-odds handicap — and accept the lower hit rate.

Smarkets and SBK are not the same product under one brand. The Smarkets exchange runs on a betting intermediary licence with back-and-lay markets, commission rates and a different price-discovery model; SBK is a traditional sportsbook. A reader choosing between them is choosing between a betting exchange model and a sportsbook model.

Verdict: the £60 headline suits a reader who already bets at 3.0-plus prices — outright winners, long-odds handicaps — and accepts the qualifier; the exchange beneath the same licence is the right venue for a reader who wants to lay bets as well as back them.

8. Hollywoodbets — a stake-back offer on a losing accumulator

Hollywoodbets is operated by Hollywoodbets International UK Limited under Gambling Commission remote licence 053028-R-330019-013 (Commission account 53028) for remote general betting standard (real events). The sports welcome offer refunds new players who deposit £10 or more by card as a free bet of up to £30 on their first qualifying losing accumulator — stake £10+, 3+ legs, odds of 4/1 or greater, settled within 7 days; one free bet per customer.

The stake-back shape is the honest form of the “risk-free” label. The original stake is always at risk; only the refund is a free bet. The qualifying accumulator requires 3+ legs at combined odds of 4/1 (5.00) or greater, settled within 7 days. The refund is a free bet up to £30, not money, and the free bet carries its own expiry.

Verdict: a fit for a reader who already builds accumulators at 4/1-plus and is comfortable accepting the original stake’s risk in exchange for the refund; the headline £30 is the maximum refund, not the expected refund, and a £10 accumulator at 4/1-plus is the smallest qualifying bet the offer will accept.

9. Octobet — a partial refund plus a casino bonus

Octobet is operated by Octopus Game Limited under Gambling Commission remote licence 062545-R-337248-006 (Commission account 62545) for remote general betting standard (real events). The sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers.

The 50%-back shape is a smaller partial refund than a matched free bet. A £100 first bet returns £50 as a free bet if it loses; a £50 first bet returns £25. The £10 casino bonus sits alongside, but the Gambling Commission’s updated promotion standards introduced on 19 January 2026 prohibit offers tying sports betting to casino play — and Octobet’s combined offering must comply with this new regulatory code.

Verdict: suitable for the customer interested in a combined sportsbook and casino incentive; note the mixed-product structure in light of Commission rules and ensure all terms are reviewed before proceeding.

10. 10bet — a 100% betting bonus with daily free bets

10bet is operated by Blue Star Planet Limited under Gambling Commission remote licence 043173-R-322899-023 (Commission account 43173) for remote general betting standard (real events). The 10bet app advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins.

The 100%-up-to-£50 bonus shape is a bonus, not a free bet — the wagering factor on the bonus will determine what clearing it costs, and under the Commission’s January 2026 rules the wagering requirement on a bonus is capped at 10x. A £50 bonus at 10x wagering requires £500 of qualifying bets before withdrawal; at the floor, the same bonus at 1x requires £50 of qualifying bets. The terms page names the wagering factor, and the reader who wants the £50 needs the factor in writing.

Verdict: a fit for the reader who wants a bonus shape and is willing to read the wagering factor on the terms page; the 10x cap is the Commission’s ceiling, not the offer’s, and a 10bet-specific figure below that ceiling is what the reader should look for.

Where the law sits behind the offers

The Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport, licenses the whole commercial market under the Gambling Act 2005, which covers Great Britain — England, Scotland and Wales. Northern Ireland is outside the Act and has its own older law; a GB licence is not a Northern Ireland licence, and the two should not be conflated.

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 set the framework; a Curaçao, Maltese or Gibraltar licence is not a substitute. The Commission’s public 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. Every operator in this guide holds one — that is the precondition for being on the list. Several brands can run under one licensee; the comparison treats each brand separately because each runs its own welcome offer and its own terms, but the licence column is the legal floor beneath them all.

Betting licence types cover 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 for betting exchanges). Coral’s licence covers both remote general betting standard and remote betting intermediary; Smarkets’ covers remote betting intermediary alone. There is no statutory list of permitted bets or markets — an operator offers markets under its own rules and the Licence Conditions and Codes of Practice (LCCP). In-play betting is offered by GB bookmakers and is governed by the operator’s licence conditions and customer-protection duties, not by a statute naming in-play as legal.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission, and Spreadex is regulated by both bodies for the two activities it runs. Spread-betting losses can exceed the deposit and that is the core risk of the product, distinct from a free bet whose stake is fixed.

The minimum age is 18, and identity verification is mandatory before the first deposit or bet — including with a free bet. Source-of-funds questions at higher spend are normal under the money-laundering rules. No state-set deposit or loss ceiling exists, so the only ceiling the reader sees is the one they set themselves.

Payments, advertising and tax in the background

Credit cards are banned for gambling in Great Britain since 14 April 2020 under LCCP condition 6.1.2 — that ban covers credit-card-funded payments through an e-wallet, not just credit cards at the till. Debit cards and bank-based payments are not covered. Coral’s welcome offer requires a debit card or instant bank transfer; Betway’s requires a debit card deposit; Hollywoodbets’ requires a card deposit; Betboro’s requires a debit card deposit. Several offers are gated by the payment method alone, and the reader’s card choice is part of the qualifying step.

Advertising is not licensed by the Commission. Marketing runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the LCCP marketing conditions. CAP Code section 16 sets the social-responsibility test for marketing: no strong appeal to under-18s, no one who is or seems to be under 25 featured gambling or playing a significant role (with an exception for marketing placed where a bet can be made directly). That rule concerns who may appear in an advertisement, not who may bet. The whistle-to-whistle industry code, in force since 1 August 2019, prevents betting advertisements on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed, with horse and greyhound racing excluded.

The player pays no tax on betting winnings in Great Britain. 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 it, 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%. Until 1 April 2027 the remote rate stays at 15%, and whether operators pass duty on through odds is not established — never write that the player is charged duty, because the duty sits on the operator’s gross profits.

Why offshore is a different deal

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 — on summary conviction up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland). The offence is aimed at the operator, not the customer. No offence aimed at a customer who merely bets on an unlicensed site was found.

The honest framing of offshore for a reader is the loss of protection. An unlicensed site does not provide GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and is not bound by the 10x bonus cap or the £150 vulnerability check. It is not “legal to use” in any simple sense, but the reader who lands on one is unprotected rather than criminal.

Enforcement is disruption, not blocking. The Commission issues cease-and-desist notices, refers sites to search engines, and works with registrars, hosts and payment providers; the Commission has been given, or is about to receive, court-order DNS blocking powers — never write that ISP blocking is in operation. None of the operators in this guide sit on the wrong side of that line.

The comparison the reader is making, then, is not “GB-licensed versus offshore” because every bookmaker on this list is GB-licensed. The comparison is between the ten GB-licensed bookmakers on their welcome offers, their feature sets and their constraints — which is the comparison this page is built to support.

Choosing the offer that fits the way you bet

A reader who bets singles on horse racing at BOG-eligible prices is a different reader from one who builds three-leg accas at 1.60-plus, and the offers on this list are written for different readers. The headline comparison is a poor guide on its own; the qualifying bet and the free-bet constraints are the real test.

For the reader who bets a single £20 at minimum odds of 2.0 and wants the largest free-bet headline, Coral and Unibet each publish £40 on a £20 qualifier, with seven-day windows on issue and expiry. The free-bet value calculation puts the £40 of free bets at roughly £16 to £20 in expected value across the typical football price band — the £40 face value is the headline, not the expected return.

For the reader who bets accumulators at 4/1-plus and accepts the original stake’s risk in exchange for a refund, Hollywoodbets’ stake-back offer is the natural fit: a £10 acca at 4/1-plus, settled within 7 days, refunds up to £30 as a free bet when it loses.

For the reader who already bets at 3.0-plus prices and wants the largest headline, Smarkets’ SBK sportsbook runs £60 in free bets on a £20 qualifying bet at minimum odds of 3.0, settled within 48 hours. The qualifier is the steepest in this guide; the headline is the largest.

For the reader who values a published wagering factor in writing, Betway’s 1x turnover at odds of 1.75 or higher is named in the terms; a reader who treats the wagering factor as a feature rather than a constraint is the right reader for that offer.

For the reader who wants a feature-led bookmaker without a headline welcome, Swifty Sports runs BOG, Cash Out, daily price boosts and live streaming; the App Store listing names Bet Builder as coming soon. Geoff Banks runs ante-post and in-play pricing without a headline welcome.

The honest closing is that the right offer is the one the reader will use, on markets they would bet on anyway, with a qualifying bet they would place regardless. An offer that requires a new kind of bet — a long-odds qualifier the reader would not normally play, a multi-leg acca at minimum odds they would not normally take — is paid for in qualifying-bet risk, and the free bet’s headline does not cover that cost.

Terms the reader should read before claiming

Three terms recur across the offers on this list, and a reader who understands them reads every offer better.

A wagering requirement is the number of times a bonus or free bet must be turned over before winnings can be withdrawn. The Commission’s January 2026 rules cap this at 10x on bonuses. A free bet whose stake is not returned and which has no further wagering condition sits outside the cap — that is the typical UK sportsbook shape — while a bonus that asks the customer to gamble the bonus amount any number of times before withdrawal sits inside the cap.

A minimum odds floor is the lowest price the qualifying bet or the free bet can be placed at. Floors of 1/2 (1.50), 1.75, 2.0 (1/1) and 3.0 appear across this guide. The higher the floor, the narrower the menu of qualifying markets, and the more the offer rewards a punter who already bets at those prices.

An expiry window is the time within which the free bet must be used, or the qualifying bet must be settled. Sky Bet’s free bets expire 30 days after crediting; Dabble’s expire in 7 days; QuinnBet’s are valid for 7 days from credit. Coral and Unibet’s free bets expire 7 days after issue; Hollywoodbets’ qualifying accumulator must settle within 7 days. A reader who treats the expiry as a deadline — and not as a suggestion — is the reader who clears the offer.

The two terms that always pay to read are the market restriction and the payment-method restriction. Market restrictions — Sky Bet’s free bets on single or each-way markets only, QuinnBet’s exclusion of Trixies, Patents and Yankees — cut the free bet’s menu. Payment-method restrictions — Coral and Unibet’s debit card or instant bank transfer, Betway’s debit card only, Hollywoodbets’ card only — gate the offer by the reader’s payment choice. A reader who deposits by an excluded method forfeits the offer; a reader who uses a free bet on an excluded market forfeits the stake.

What this page is not

This page does not name a sure bet, a winning system, or a predicted outcome. No such thing exists in sports betting, and a reader who acts on a predicted outcome loses real money on the page’s word. The arithmetic here is statistical: payout share, margin, expected free-bet value, expected turnover — averages over many bets, not guarantees for any single bet. A reader who treats them as guarantees is reading them wrong.

This page does not name a “best” bookmaker in any final sense. The ten reviewed here are different products for different readers, and the page’s job is to set out the differences honestly so a reader can choose. The page is not a tip sheet, not an affiliate shortlist, and not a recommendation to sign up.

This page does not print a promo code, a bonus code or a voucher code. The Commission’s marketing rules and every operator’s terms discourage that route, and the offer’s worth is the same with or without a code. A reader who finds a “code” through a third-party site is reading marketing copy, not the operator’s terms.

Frequently asked questions

How do I sign up with a betting site?

Pick a GB-licensed bookmaker from the Commission’s public register and open an account on its site or app. You will be asked for name, address and date of birth, and the operator will verify those before you can deposit, place a bet or use a free bet. Deposit by debit card or bank transfer (credit cards are banned for gambling in Great Britain), place your qualifying bet at the minimum price stated in the terms, and the free bet credits on settlement of the qualifying bet. The free bet then has its own expiry window, which is usually shorter than the welcome offer’s headline suggests.

How do I sign up with a sportsbook?

A sportsbook sign-up is the same shape as a betting-site sign-up — verification before deposit, debit card or bank transfer for the qualifying deposit, a qualifying bet at the minimum odds stated in the offer, settlement before the free bet credits. The difference is the product mix: a sportsbook offers sports markets, sometimes with a casino tab attached. Mixed-product promotions tying the sportsbook welcome to casino play are banned under the Commission’s promotion rules in force since 19 January 2026, so a sportsbook welcome that names casino play alongside the free bet is the one to read carefully.

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 — the kind of offer common on casino products — required £500 of bets before withdrawal; under the cap, no more than £100 can be required. The cap applies to bonuses; whether it applies to free bets with no wagering condition is not established. Mixed-product promotions, such as an offer that requires betting on football to unlock free spins, are banned under the same rules.

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

Minimum odds are the lowest price at which the qualifying bet or the free bet can be placed. Coral and Unibet set the floor at 2.0 (1/1); Smarkets’ SBK sets it at 3.0; Betway’s £40 offer sets it at 2.0. The wagering requirement is the number of times a bonus must be turned over before withdrawal — capped at 10x on bonuses since 19 January 2026. A free bet whose stake is not returned and which carries no further wagering condition is a different beast from a bonus that must be turned over before winnings can be withdrawn, and the Commission’s 10x cap applies to the latter rather than the former.

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

Because that is what makes the offer a free bet rather than a cash bet. A £10 cash bet at decimal odds of 2.00 returns £20 — £10 stake plus £10 profit — and the £10 stake is yours because you staked it. A £10 free bet at the same odds returns £10 in profit because the £10 stake is the bookmaker’s, not yours. The free-bet value calculation makes the difference concrete: a £10 free bet at decimal odds of 1.90 on a market with a 5% margin is worth roughly £4.50 in expected value, well below the £10 face value. The expected value of a free bet is lower than the headline because the stake is not returned, and that single rule is the arithmetic behind the offer’s price.

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, casino, bingo and lottery. An offer that ties a sportsbook deposit to a casino bonus, such as “stake £10 on football for free spins”, is banned under the rule. A sportsbook welcome that publishes a casino bonus alongside the free bet — Octobet’s, for example — is the shape the rule is aimed at, and a reader should check the operator’s current terms before claiming.
