A new betting account is a free hit at someone else’s marketing budget, and the marketing budget is generous. Coral gives £40 in free bets when you stake £20. Unibet gives £40 on the same shape. Sky Bet credits three £10 free bet tokens after a 5p first wager. BetGoodwin hands out £15 across three separate tokens. Spreadex tops the visible pile at £60 from a £10 fixed-odds opening bet. The numbers are loud; the questions behind them are quieter and matter more: how much of that money reaches you as withdrawable cash, what conditions sit between you and it, and which bookmaker’s terms turn a generous-looking offer into a treadmill.

The honest lead for this page sits inside one rule change. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x, and a “mixed-product” promotion — an offer that drags a sports bettor into a casino or bingo wallet — is banned. The cap answers a specific harm: bonuses so heavy on turnover that a customer cannot realistically withdraw. It does not abolish heavy offers; it caps them. A £10 bonus at 50x, the kind of requirement that turned bonuses into products in their own right, can no longer exist; a £10 bonus at 10x can, and does, on almost every name in this guide. Read what follows as a way of sorting the genuinely fair from the merely compliant.

Fundamentals: what a sign-up offer actually is

A sign-up offer is a contract written into the small print of a sportsbook’s promotion page. It has four parts, and most readers only ever read the first. The headline number — “£40 in free bets”, “£30 in free bets”, “bet £10 get £15” — is the marketing. The mechanics sit beneath it: how much you must deposit, what odds your first bet must carry, what shape the free bet takes when it lands, and how long it lives.

A free bet is a token. Stake it on a market; if it wins, the operator keeps your stake and pays out the profit at the stated odds. A £10 free bet at 3/1 returns £30, not £40. That asymmetry is the first number worth holding on to. Free bets are not cash; they are a one-shot stake whose profit you keep and whose stake you do not. Some promotions do return the stake — BetGoodwin’s £5 sports bet, for instance, is a real wager that returns the stake on a win — but the default across the UK market is the stake-not-returned model, and the default is what most offers follow unless the terms say otherwise.

The second part is the qualifying bet. To unlock the free bet or bonus, you place a first wager that meets a minimum stake and minimum odds. Coral asks for £20 at minimum odds of 2.0 (1/1). Unibet asks for the same. Sky Bet asks for 5p at odds of 1/1 or greater, on a single or each-way bet. Spreadia asks for £10 at minimum odds of 1/2. VBet asks for £10 that loses. Each bookmaker sets its own figure, and the figure shapes who can actually claim. A reader with a small budget can clear Sky Bet on the cost of a chocolate bar; a reader who only stakes on long-odds bets will find VBet’s “stake £10 that loses” straightforward in concept but punishing in practice if they win.

The third part is the free-bet currency itself. Some operators slice the bonus into tokens. Coral issues £40 in free bets; Sky Bet credits three £10 tokens; BetGoodwin splits £15 into £5 on a sports bet, £5 on an acca, £5 on a Sub-Cover. Tokens cannot be combined; a token wins or it does not, and on a loss the token is gone. A bonus in a single chunk lets the reader spread risk across legs of an accumulator; tokens pin the reader to one market per token. The shape changes the bettor’s freedom.

The fourth part is the clock. Coral’s free bets expire seven days after issue. Unibet’s expire within seven days. BoyleSports’ Acca Insurance refunds as a free bet that expires in seven days. QuinnBet’s free bets are valid for seven days from credit. Spreadia requires the qualifying bet to be placed within 28 days of opening the account. A free bet is a perishable product, and expiry dates are why a £30 headline can land as much less in your account: by the time you remember the token, the bet that would have justified it is gone.

The four parts in one sentence

Headline, mechanics, currency, clock. Most readers read the first and skip the other three; most of the disappointment in a sign-up offer lives in the parts that were skipped.

The landscape: how offers compare in shape

The ten bookmakers reviewed on this page all run a sign-up promotion. The promotions differ less in headline value than they appear to. Coral and Unibet share the same headline and the same qualifying bet; the difference is the rest of the sportsbook, not the welcome mat. Smarkets’ SBK differs structurally: a £20 deposit, a £20 bet at minimum odds of 3.0, returns £60 in free bets within 48 hours, which is a heavier qualifying bet with a heavier payout in return.

The split between stake-returned and stake-not-returned is the clearest shape. Spreadia gives £60 in free bets usable across fixed odds and spread betting; those are stake-not-returned tokens. Coral’s £40 is also stake-not-returned. VBet’s £10, on the other hand, is a free bet credited only when the qualifying bet loses — a refund-in-tokens model that gives the reader nothing on a winning first bet. Spreadia’s qualifying bet, by contrast, returns the free bets regardless of whether the first bet wins or loses. The two models sit on opposite sides of the same question: does the reader get something for winning their first bet, or only for losing it?

Some offers add a wagering requirement on the bonus. Under the Commission’s January 2026 cap that requirement cannot exceed 10x. A reader converting a bonus into withdrawable cash therefore faces a fixed number of bets at fixed minimum odds. That calculation is the single piece of arithmetic worth doing on this page, and it sits in the section on bonus mechanics further down. The cap applies to bonuses that carry a wagering condition; whether it applies to a free bet with no wagering condition is not established in the public rule, and the question is left open in this guide.

The pricing of the gift

A free bet worth £10 at 3/1 returns £30 if it wins. A £10 free bet at 5/1 returns £50. The headline figure of the offer tells you the stake; the odds of the bet you place with it tell you the value. A reader who picks long-odds markets extracts more from each token. A reader who picks short-odds favourites extracts less. The offer is a token, and the market you spend it in is the variable the offer does not name.

Statute: the rules that govern every offer on this page

Every bookmaker reviewed here is licensed by the Gambling Commission for remote betting in Great Britain. Licensing is not optional. 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. A Curaçao, Maltese or Gibraltar incorporation is not a substitute. Northern Ireland sits outside the Gambling Act 2005 and has its own older law, so this guide uses “Great Britain” or “GB-licensed” rather than “UK-licensed”.

The Commission runs a public register searchable by business name, trading name, domain or account number. That register is the test of whether a brand holds a licence; the answer is the entry, the date the entry was last updated, and the categories against which the licence is granted. Categories matter: a remote general betting standard (real events) licence covers sports on real fixtures, virtual events require a separate category, and a remote betting intermediary licence is what an exchange runs on. Smarkets’ list places it on the intermediary category; bet365, Coral, William Hill, Unibet, VBet, Betmaster, Kwiff, NetBet, BetGoodwin, Geoff Banks and LiveScore Bet all sit on the general betting category. The site a reader sees in their browser proves nothing: licensed operators use .com as well as .co.uk, and a .com address is not, on its own, an offshore mark. The register settles it.

Several brands can run under one licensee, and the same company can run an exchange and a sportsbook side by side. Ladbrokes and Coral share LC International Limited as their licensee. Paddy Power and Betfair share Flutter Entertainment’s UK arm. The published list of operators on the Gambling Commission’s register is much longer than the ten names reviewed here; a place in this comparison is not a licence, and a licence is not an endorsement.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission. Spreadia runs both: fixed-odds betting under a Gambling Commission licence, and financial spread betting under an FCA authorisation. The two regimes carry different rules; the FCA regime treats spread betting as a financial product and spread betting losses can exceed the deposit. A reader using Spreadia for fixed odds should know which side of the regulatory line they are on at any moment. The fixed-odds side is governed by the Commission and the consumer protections outlined below; the spread side is governed by FCA conduct rules and its own disclosures.

The January 2026 promotion rules

Two rules from the Commission’s January 2026 changes dominate this page. The first caps wagering requirements on bonuses at 10x. A £10 bonus can no longer carry a 50x rollover, the level at which a bonus stops being a sweetener and starts being a product. Under the cap, the maximum turnover required to clear a £10 bonus is £100. Above that, the offer breaches the licence condition. The cap answers a specific consumer harm: customers who accepted bonuses they could never realistically withdraw.

The second rule bans mixed-product promotions: any offer that requires gambling on two or more product types, such as betting and casino, betting and bingo, or betting and lottery. The example the Commission uses in guidance is “bet on football to get free spins”. That offer no longer exists in Great Britain. A sports bettor cannot be pulled into a casino wallet as a condition of claiming a sports welcome. Whether the wagering cap applies to free bets with no wagering condition is not established; the rule addresses the cap on bonuses, and free bets sit outside it. Free bets also carry no money value of their own to cap: a £10 free bet returns the profit on a winning market, not £10 in cash.

What the rules do not do

The cap does not abolish generous offers. It caps them. A bookmaker can still credit £40 in free bets to a qualifying £20 stake, as Coral does; that offer sits inside the cap because free bets with no wagering condition are not subject to it. The cap also does not regulate stake limits, minimum odds on qualifying bets, expiry windows or the number of free bet tokens. Those terms remain the operator’s choice, and they are where most of the variation between offers lives. The mixed-product ban does not end cross-promotion across an operator’s own sites; it ends the tying of a sports offer to a casino wallet. Operators continue to advertise their casino products on their sportsbook pages.

Advertising and the ASA

Advertising is not licensed by the Commission. It is regulated by the Committees of Advertising Practice (the CAP Code for non-broadcast media and the BCAP Code for broadcast), enforced by the Advertising Standards Authority, alongside the Commission’s own marketing conditions in the Licence Conditions and Codes of Practice. CAP Code section 16 sets the social responsibility rules: marketing must not be of strong appeal to under-18s, no one who is or seems to be under 25 may be featured gambling in it, and the rule concerns who may appear in an advertisement, not who may bet. Operators are responsible for their affiliates’ marketing. “Whistle-to-whistle” is an industry code, not law: since 1 August 2019 betting advertisements are not broadcast five minutes before a live sporting event to five minutes after, before the 9 pm watershed. Horse and greyhound racing are excluded.

The Premier League clubs’ voluntary withdrawal of gambling sponsorship from the front of matchday shirts, from the 2026/27 season, is voluntary, not law; sleeves and pitchside hoardings remain. None of this changes the sign-up offer itself. What it changes is the surface a reader meets the offer on.

Safeguards: what licensed play actually buys you

A Gambling Commission licence buys a set of consumer protections that an unlicensed site cannot match. The first is identity verification. Since 7 May 2019, a remote betting customer must pass verification of name, address and date of birth before they can deposit or gamble, including with a free bet. Anonymous play is gone from the licensed market. A reader who wants to bet without showing their documents has nowhere to do that legally.

The second is GAMSTOP. Since 31 March 2020 every online operator licensed by the Commission has been required to take part in GAMSTOP, the national multi-operator self-exclusion scheme. A customer who registers with GAMSTOP is barred from opening new accounts, depositing or gambling with any participating operator for the period they choose: 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. GAMSTOP covers online sites and apps; betting shops run a separate service.

The third is the financial vulnerability check. Since 30 August 2024, and tightened from 28 February 2025, a licensed remote operator runs a public-record check when a customer’s deposits minus withdrawals exceed £150 in a rolling 30-day window. The check looks at public records such as bankruptcy orders or county court judgments. It is not an income check and it is not a credit reference check. The wider “financial risk assessments” — what the press calls affordability checks — are announced by the Commission in a staged plan (a Commission article of 7 July 2026 confirms the staged approach), with no start date. Write them as announced, staged, no start date, not in force.

The fourth is the deposit limit. Operators must offer a gross deposit limit on a fixed time frame. The first changes applied from 31 October 2025; a second phase was postponed to 30 September 2026, and whether that phase is live is not established. There is no state-set ceiling on deposits or losses: limits are the customer’s own choice.

The fifth is credit-card discipline. Since 14 April 2020 credit cards have been banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. A debit card or a bank-based payment such as Open Banking or instant bank transfer is fine; a credit card is not.

The help that sits outside the licence

The licensed framework is a floor, not a ceiling. Help is the part that sits above it. The National Gambling Helpline (run by GamCare), GambleAware’s online support, NHS gambling clinics, and Gamblers Anonymous meetings provide help independent of any operator. A reader who finds themselves chasing losses, betting more than they planned, or hiding bets from people they live with should reach out before the next deposit.

A self-exclusion through GAMSTOP is the strongest single step a customer can take. It does not require a conversation with an operator. It blocks the licensed online market for the period selected. It does not block betting shops, where a separate self-exclusion scheme applies, and it does not block unlicensed sites, which is one of several reasons the unlicensed market remains a poor option. The full suite is the strongest version of a decision to stop.

What unlicensed play loses

A reader who bets with a site that does not hold a Gambling Commission licence loses each of those protections. No GAMSTOP coverage, no approved dispute-resolution body, no British consumer redress if funds are withheld, no Commission complaints route. The 10x bonus cap does not bind the operator. The £150 vulnerability check does not apply. Identity verification is the operator’s choice, and the operator’s customer service is the only complaints path. The Commission’s enforcement powers are aimed at operators, not customers; providing gambling facilities in Great Britain without a licence is an offence under section 33 of the Gambling Act 2005, with penalties of up to 51 weeks’ imprisonment or a level-5 fine on summary conviction (six months in Scotland). A customer who places a bet on an unlicensed site commits no offence under the framework as currently published, but the operator does.

The honest framing is two-sided. Licensed play means identity checks, deposit limits, GAMSTOP, the bonus cap. Unlicensed play means none of those and possible loss of funds. Neither is “the safe choice” by default; the reader’s choice is between one set of trade-offs and another. What this guide does not support is the bet that the unlicensed market is the easier one. The bonus headlines are larger because nothing stops them being larger.

Incentives: bonuses, free bets and what each is worth

The terminology is the first trap. “Risk-free bet” usually means a free bet credited only if the qualifying bet loses, which is the opposite of risk-free. “Free bet” means a token whose stake is not returned with the winnings. “100% bonus” usually means a bonus equal to the deposit, with its own wagering requirement, expiry and minimum-odds rule. Each term has a definition in the small print, and each term is used in headlines because the headline is the marketing. The Commission’s January 2026 cap on wagering requirements limits how heavy that marketing can be. It does not redefine the terms.

A bonus is a credit to a bonus wallet. To convert it to cash, a customer wagers it through a turnover multiple at minimum odds within an expiry window. A £10 bonus at 10x means £100 of qualifying bets; under the January 2026 cap that is the maximum. A £10 bonus at 5x means £50. The multiple sits in the offer terms; the minimum odds sit there too. QuinnBet’s free bets require minimum odds of 1/2 (1.5 decimal) and maximum odds of 50/1, with straight accumulators allowed but Trixies, Patents and Yankees not. The minimum odds filter is what stops a customer clearing a bonus on a 1.01 line.

A free bet is a token. It can be spent on a market; if the market wins, the profit lands in the cash wallet; the stake does not. Free bets do not, in the licensed UK market, typically carry a wagering requirement, which is why the Commission’s cap is read as applying to bonuses rather than free bets. The cap’s exact scope on free bets with no wagering condition is not established in the published rule. The bonus-turnover arithmetic in this guide therefore uses the bonus form, where the cap is unambiguous.

A price boost is a margin cut on a chosen market. Bet365 offers Super Boosts and daily Bet Boosts; William Hill runs a Football Acca Boost that scales from 3% on a double up to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet, running until 30 May 2027. A boost adds a percentage to the odds of a chosen bet; the bet’s stake is paid back normally. Boosts are not bonuses and do not carry a wagering requirement. They are the closest a licensed sportsbook comes to simply improving its price.

An accumulator insurance returns the stake as a free bet if one leg of an accumulator loses. BoyleSports Acca Insurance requires opt-in, a £5 minimum stake, minimum odds of 1/2, and pays a maximum refund of £20 as a free bet that expires in 7 days; bets must be placed and settled on the same day. Insurance costs nothing on entry and pays nothing on a win; it pays only on a near-miss. The maximum refund is the cap on what the offer is worth.

A cashback returns a percentage of net losses over a period. Cashback offers on sign-up are rarer in the licensed UK market than free bet offers, because the Commission’s framework limits the structure of promotions. The closest equivalents are the loyalty and acca programmes: BoyleSports Acca Loyalty requires opt-in, a £5 minimum stake, minimum combined odds of 3/1 and 5 or more settled legs, with a free bet expiring after 7 days. Spreadia’s Acca Boosts give a cash boost from 5% up to 100% on football accumulators of three or more selections.

What the £40 actually costs a bookmaker

The arithmetic on a Coral-style offer is straightforward. Coral pays £40 in free bets when a customer stakes £20 at minimum odds of 2.0. The expected cost to Coral is the average profit the £40 of tokens produces when spent at Coral’s typical margin. At a 5% market margin, £40 of stake-not-returned tokens returns about £38 of profit to the customer on average — the operator keeps £2 of margin on the £40 of turnover. The promotion costs Coral about £38 in expected value. The £40 headline is a number; the expected cost is another number beneath it, and the gap between them is the marketing.

The same arithmetic on Spreadia’s £60 free bets for a £10 fixed-odds qualifying bet returns about £57 of profit on average, at the same margin. The headline is bigger; the cost to the operator is bigger; the customer’s gain is bigger. The reason Spreadia sets a smaller qualifying bet than Coral — £10 instead of £20 — is the cost of the bonus: a smaller qualifying bet is a cheaper access unit for the operator and a lower barrier for the reader, and the headline is the lever on the customer’s decision.

The bonus-turnover arithmetic, and why the 10x cap changes the maths

The calculation this page runs is the bonus-turnover calculation, and the inputs are the offer terms and the Commission’s January 2026 cap. A £10 bonus at the maximum 10x wagering factor requires £100 of qualifying bets. At a £10 stake per bet that is ten bets. At minimum odds of 1/2, each bet clears a portion of the wagering; at minimum odds of 5/1, each bet clears the same portion. The factor and the stake per bet determine the number of bets; the minimum odds determine which markets count.

For the licensed UK market the post-19 January 2026 band is £100 of qualifying bets on a £10 bonus, ten bets at 1/2 or better, with the bonus credited to the cash wallet on completion of the wagering. Some offers use a lower factor — 5x, 3x, 1x — and require fewer bets. The 10x ceiling is a maximum, not a floor. The arithmetic the reader actually runs depends on the terms they have in front of them, and those terms live on the promotion page, not on this page. What this page states is the band: ten bets of £10 each, at minimum odds of 1/2 or greater, within the offer’s expiry window, is the maximum turnover required to clear the maximum permissible bonus under the cap.

Why expiry matters

Coral’s free bets expire seven days after issue. Unibet’s expire within seven days. QuinnBet’s expire in seven days. Spreadia requires the qualifying bet within 28 days but does not state the free-bet expiry on the same page. BoyleSports’ Acca Insurance free bet expires in 7 days. Seven days is the modal expiry in this market. A reader who does not use a free bet within seven days loses it; a reader who lets several tokens expire loses several tokens. The headline value of an offer with three tokens that each expire in seven days is the same as the headline value of an offer with one token that expires in seven days, but the practical value depends on whether the reader uses them. A reader who bets once a week reads three seven-day tokens as one bet’s worth of stake-not-returned value; a reader who bets daily reads them as three bets’ worth. The token shape is part of the offer.

Shortlist: the ten bookmakers reviewed, compared

The table below names each operator, the Gambling Commission remote licence number and licence holder that holds it, and what the operator’s own terms state on the relevant offer. The licence numbers are what a reader verifies against the Commission’s public register; the offer terms are what a reader reads before claiming.

The headline alone does not pick either. A reader choosing between Coral and Smarkets SBK compares £40 in free bets at minimum odds of 2.0 with £60 in free bets at minimum odds of 3.0, both after a £20 qualifying bet. Coral’s offer is more permissive on the qualifying bet; SBK’s offer is larger. A reader who prefers 3.0 odds for their opening wager may find the SBK headline better, while a reader starting with a favourite takes the more permissive Coral terms.

What each operator actually runs

LiveScore Bet takes debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank and Revolut Pay. The method list reads as a reader’s options at the cashier: a card, an e-wallet, an open-banking transfer and a fintech app. The list is wider than many of its peers, and the welcome offer sits on top of it rather than inside it. The bookmaker a reader uses for one click at a checkout is a bookmaker a reader keeps, and LiveScore’s payment menu is built for that kind of reader.

VBet runs a refund-in-tokens welcome: a £10 free bet credited only when the qualifying £10 bet loses. The structure suits the reader who expects to lose the first bet, which is most readers on most markets. It does not suit the reader whose first bet wins; that reader takes nothing from the welcome. The free bet carries a wagering treatment aligned with the licensed market’s standard.

Betmaster is a smaller brand. Its home page cites the Gambling Commission account number, which is what a reader looks for first. The brand runs sports and casino on a single platform; the welcome offer structure follows the licensed market’s standard.

Geoff Banks publishes its app through GB Sports Advisors Ltd. The product is live in-play prices and ante-post prices on future events — two specific bets that suit the reader with a long horizon, where ante-post is the form and live in-play is the context. The welcome offer is the standard free-bet shape; the specialism is the betting menu.

Coral runs the £40-for-£20 welcome covered in the table above, plus 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. The welcome is the headline; the daily content is what keeps a reader coming back. The Odds Booster is the closest Coral comes to simply improving its price; the Reward Shaker is the loyalty mechanic; the free-to-play games are the engagement layer.

Smarkets runs an exchange under a betting intermediary licence. SBK is the sportsbook side of the same company. The welcome is the headline; the exchange offers a different proposition entirely, with back and lay bets and rates stated on the exchange’s own terms. A reader who likes the welcome should read both sides of the company before settling on the sportsbook.

bet365 runs Bet Builder+ across pre-match and in-play, Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. The bookmaker is the deepest bet-builder product in the licensed UK market, and the welcome sits beneath a feature set that is the reason a reader signs up. The offer structure is the access product; the bet builder is the retention product.

Kwiff’s Supercharge feature can instantly boost the odds on a bet, from 2/1 to 20/1 on the example Kwiff uses, and applies to single or multi bets on any sport. Kwiff also offers Bet Builder and Bet Builder+, which combines Bet Builder bets from different games, plus a guaranteed weekend acca boost. The product is the boost; the welcome is the entry fee. A reader who values a boost on a chosen market reads Kwiff differently from a reader who values a fixed welcome.

BetGoodwin’s welcome is three tokens: £5 on a sports bet (a real wager that returns the stake on a win), £5 on an acca, £5 on a Sub-Cover bet. The token shape is the offer. A reader who plans to bet a £10 sports wager on day one and an acca at the weekend reads three tokens as three bets; a reader who bets once reads them as one bet’s worth.

NetBet runs Daily Boosts, Profit Boosts and free bet offers, with a Bet Builder featuring instant dynamic odds and sports stats for major leagues. The product is breadth: boosts, builders and stats across a wide menu. The welcome sits on top of a content-led sportsbook.

The licence ledger, one line per operator

A licence is not a recommendation. The register lists many more operators than the ten reviewed here, and every name in this guide is on it. The licence numbers in the table above are the figures to check; the licence holders are the corporate names behind the brand. A reader who wants to be sure of a brand’s status searches the Commission’s public register by business name or domain and reads the entry. The register is the only test of “is this brand licensed?”.

Assessment: who each bookmaker suits, and where each one fails

The operator reviews below name the headline product, the welcome offer, the structural feature that sets the operator apart in this comparison, and the kind of reader the operator actually suits. Each review closes on a verdict: what the page makes of the brand, not a marketing line carried forward from the operator’s site.

LiveScore Bet

LiveScore Bet runs a sportsbook on a Gibraltar-incorporated licence held by LiveScore Betting and Gaming (Gibraltar) Limited, with payments spanning debit cards, e-wallets, open-banking and Revolut Pay. The payments menu is the clearest reason a reader picks one bookmaker over another, and LiveScore’s menu is the widest in this guide. The welcome offer follows the licensed market’s standard. A reader with a Revolut account or who prefers Pay by Bank reads LiveScore’s cashier as built for them; a reader who only carries a debit card reads LiveScore the same as everyone else. Verdict: LiveScore Bet suits a reader who prioritises the cashier over the welcome offer, and the welcome itself is competitive without being a market leader.

VBet

VBet runs a refund-in-tokens welcome on a licence held by SCGO Limited. The structure is what sets it apart: a £10 free bet only when the qualifying £10 bet loses. The structural bet suits a reader who assumes their first bet will lose. The brand is smaller than Coral or bet365; the welcome is the access product. Verdict: VBet is the right choice for a reader who plans a small first bet on a market they expect to lose, and who reads a refund-in-tokens offer as the better deal than a free bet regardless of outcome. It is the wrong choice for a reader whose first bet they expect to win.

Betmaster

Betmaster runs a sportsbook on a Malta-registered licence held by BM Solutions GB Ltd, with the licence account number cited on the home page. The offer structure follows the standard. The product is breadth, not depth; the welcome is not a market leader. Verdict: Betmaster is the right choice for a reader who values the licence status over the welcome headline and who reads the offer as a small thank-you rather than a key reason to sign up. It is not a destination for a reader who wants the deepest bet builder or the most generous free bet.

Geoff Banks

Geoff Banks runs live in-play prices and ante-post prices on future events through an app published by GB Sports Advisors Limited. The product is two specific bets: live in-play and ante-post. A long-horizon bettor on horse racing or major championships is the obvious reader; an in-play bettor on football is the other. The welcome is the standard. Verdict: Geoff Banks stands out for a bettor whose pattern is long-horizon ante-post or short-cycle in-play, and who prefers a smaller brand over the multi-sport weight of bet365.

Coral

Coral runs the £40-in-free-bets-for-£20 welcome on a licence held by LC International Limited, qualifying with a debit card or instant bank transfer, free bets issued within seven days and expiring seven days after issue. The product set is wider: 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. Coral is the most complete product offering alongside bet365 in this guide. Verdict: Coral is the right choice for a reader who wants a competitive welcome offer with a depth of product around it — boosts, loyalty, free-to-play. The £40 headline is matched only by Unibet; the daily content is what tips Coral over the line for readers who will use it.

Smarkets and SBK

Smarkets runs an exchange under a betting intermediary licence held by Smarkets (Malta) Limited. SBK is the same company’s sportsbook. The SBK welcome is £60 in free bets within 48 hours after a £20 first deposit and a £20 bet at minimum odds of 3.0. The exchange side is a separate product with separate rules: back and lay bets, rates stated on the exchange’s own terms. Verdict: Smarkets is the right choice for a reader who wants both an exchange and a sportsbook under one roof and who already plans a £20 bet at 3.0 — the SBK offer is genuinely heavy when claimed at face. The exchange and the sportsbook are not interchangeable, and a reader who wants only one should pick that one.

bet365

bet365 runs Bet Builder+ across pre-match and in-play, Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. The licence account is held by Hillside (UK Sports) ENC. The product is the deepest in the licensed UK market for bet builders and boosts. The welcome sits beneath a feature set that is the reason a reader signs up. Verdict: bet365 is the right choice for a reader whose reason to sign up is the bet builder or the boost mechanic, not the welcome offer. The offer is competitive without being a market leader; the depth of product around it is what the welcome cannot compete with.

Kwiff

Kwiff’s Supercharge feature can boost the odds on a bet instantly, from 2/1 to 20/1 on the example Kwiff uses, and applies to singles or multis on any sport. The licence account is held by Eaton Gate Gaming Limited. The product is the boost; the welcome is the entry fee. Kwiff also offers Bet Builder and Bet Builder+, combining Bet Builder bets from different games, and a guaranteed weekend acca boost. Verdict: Kwiff values the boost on a chosen market over a fixed welcome offer, and suits those who bet across singles and multis. It falls short for a pure-accumulator bettor who prefers the certainty of a fixed welcome.

BetGoodwin

BetGoodwin’s welcome is “Bet £10 & Get £15 in Free Bets” — three tokens of £5 each, on a sports bet, an acca and a Sub-Cover bet. The licence account is held by Goodwin Racing Limited. The token shape is the offer. The first token is stake-returned; the others are stake-not-returned tokens. Verdict: BetGoodwin is the right choice for a reader who plans to bet across the three token types — a single, an acca and a Sub-Cover — and who reads three tokens as three bets’ worth. It is the wrong choice for a reader who plans only singles and reads three seven-day tokens as one bet’s worth of stake-not-returned value.

NetBet

NetBet runs Daily Boosts, Profit Boosts and free bet offers, with a Bet Builder featuring instant dynamic odds and sports stats for major leagues. The licence account is held by Netbet Enterprises Limited. The product is breadth across boosts, builders and stats. The welcome sits on top of a content-led sportsbook. Verdict: NetBet is the right choice for a reader who values content around the bet — stats for major leagues, instant dynamic odds on the bet builder — and who reads the offer as a thank-you rather than a key reason to sign up. The product is broader than the welcome is generous.

The maths behind the headline: bonus turnover in the post-19 January 2026 market

The arithmetic on a bonus runs as follows. A bonus of £B carries a wagering factor of W and a minimum odds of M. The required turnover is £B × W. At a stake of £S per bet, the number of bets required is (B × W) / S. Bets must be at or above the minimum odds M to count. At the maximum permissible W of 10 under the Commission’s January 2026 cap, a £10 bonus requires £100 of qualifying bets; at a £10 stake that is ten bets; at a £5 stake, twenty bets; at a £1 stake, one hundred bets. Bets below the minimum odds do not count.

For a £10 bonus at the maximum 10x wagering factor with a minimum odds of 1/2 (1.5 decimal) and a £10 stake per bet, the required turnover is £100 and the number of bets is ten. The expiry window is the offer’s stated window — most free bets in this market expire in seven days, and a £10 bonus clearing window would typically be longer, often 30 days, but the exact window sits in the offer’s terms. Bets at 1/2 count; bets at 1/3 do not.

The expected cost of clearing the bonus depends on the margin of the markets the customer bets on. At a 5% margin, £100 of turnover costs the customer about £5 in expected loss; the bonus pays £10 in expected value, so the customer clears the bonus ahead by £5 on average. At a 10% margin, the cost is about £10 and the customer breaks even. At a 15% margin, the cost is about £15 and the customer is behind. The expected cost is therefore the offer’s margin × the required turnover, and the offer is worth taking when the margin is below the bonus / turnover ratio.

The 10x cap changes the calculation by changing the maximum required turnover. A £10 bonus at the maximum 10x requires £100 of qualifying bets; the same bonus at the previous 50x cap required £500. The customer who accepts a 10x bonus at a market with a 5% margin clears the bonus ahead by £5 on average; the customer who accepts a 50x bonus at the same market clears behind by £15. The cap turns a market of risky bonuses into a market of cleared bonuses. A reader who reads the headline alone does not see this; a reader who reads the bonus-turnover arithmetic does.

The Commission does not cap the bonus amount or the money value of a free bet. A £10 bonus at 10x is the same as a £100 bonus at 10x under the cap, in the sense that the turnover scales with the bonus. A £100 bonus at 10x requires £1,000 of qualifying bets at a £10 stake, or one hundred bets. The expected cost at a 5% margin is £50, against a £100 bonus value: a £50 expected gain on average. A reader with the bankroll to clear a £100 bonus at 10x is in a different position from a reader clearing a £10 bonus at 10x. The cap is the same; the bankroll is not.

The arithmetic in one clause

Ten bets of £10 each at minimum odds of 1/2 or greater, within the offer’s expiry window, is the maximum turnover required to clear the maximum permissible £10 bonus under the Commission’s January 2026 cap. At a typical 5% market margin the bonus clears ahead by about £5 on average; at a 10% margin the customer breaks even. Beyond that, the cost of clearing outweighs the bonus.

How to read an offer before claiming it

The four-part check applies to every offer in this guide. Read the headline, then the mechanics, then the currency, then the clock. If any part is unclear, the offer’s full terms are the place to read it; this page is a comparison, not a substitute for the small print.

The mechanics: what is the qualifying bet, what are the minimum odds, what is the minimum deposit? Sky Bet asks for 5p at 1/1 — the lowest barrier in this guide. Spreadia asks for £10 at 1/2 — a small stake, modest odds, on a fixed-odds wager. VBet asks for £10 that loses — the qualifying bet must lose for the welcome to credit. The mechanics filter the offers into the ones you can actually claim.

The currency: stake-returned or stake-not-returned tokens? A stake-returned token is a real bet whose stake comes back with the winnings; a stake-not-returned token is a one-shot stake whose profit lands without the stake. The headline figure of £40 in free bets reads as cash and behaves as tokens; the difference matters at the cashout screen.

The clock: when does the free bet expire? Most free bets in this guide expire in seven days. The qualifying bet often has its own clock — Spreadia’s 28 days. A free bet that expires before the next round of fixtures on your sport is a free bet you cannot use; an offer that reads as generous in headline reads as nothing in practice.

The cap: what is the maximum refund, the maximum free bet winnings, the maximum stake during clearing? The cap is in the offer terms; the cap is what stops a generous offer from being generous. BoyleSports Acca Insurance caps the refund at £20; William Hill’s Football Acca Boost caps at £10,000 per online bet; free bets across the market carry their own caps on what they can return.

The decision tree

A reader with a small budget starts at Sky Bet: 5p at 1/1 unlocks £30 in three £10 tokens. A reader with a standard £20 to spend has three competing offers: Coral (£40 for £20 at 2.0), Unibet (£40 for £20 at 2.0), and SBK (£60 for £20 at 3.0). Coral and Unibet share their headline and their qualifying bet; SBK’s headline is bigger and its qualifying bet is heavier. A reader with a long-shot first bet in mind takes SBK; a reader with a coin-toss favourite takes Coral or Unibet.

A reader who values the cashier takes LiveScore Bet: debit cards, e-wallets, open banking and Revolut pay. A reader who values the bet builder takes bet365. A reader who values the boost takes Kwiff. A reader who wants a smaller brand with deep ante-post or in-play takes Geoff Banks. A reader who wants token shape takes BetGoodwin.

A reader who wants to bet on the offer’s terms reads the offer’s full terms. The Commission’s public register is the test of the licence; the licence number in the table above is the search term. The minimum deposit, the minimum odds, the minimum stake, the expiry window, the maximum refund, the maximum free bet winnings: each sits in the offer’s own page. None of them sits on this page.

The bigger picture: tax, advertising, and the limits of the licensed market

The player pays no tax on betting winnings in Great Britain. That is general information, not tax advice; a professional gambler should ask HMRC or an adviser. General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15% (HM Government policy paper of 26 November 2025). Until 1 April 2027 the remote rate stays at 15%. Spread betting has its own rates (3% financial, 10% other).

Whether operators pass duty on through odds is not established. The pricing of odds sits inside the operator’s margin, and the margin sits inside the headline price. A 5% market margin is what the customer pays, and what sits inside that 5% is a matter of the operator’s pricing. The Commission’s statutory levy is a separate charge, not a tax, and is not visible in the odds.

Advertising sits under the ASA, the CAP Code and the BCAP Code, with the LCCP marketing conditions on top. The CAP Code section 16 rules govern the social responsibility content of marketing; the BCAP Code governs broadcast. The whistle-to-whistle code is industry self-regulation. None of this changes the offer. What it changes is the surface the reader meets the offer on.

The licensed market is not a closed system. The Commission’s enforcement is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers. The Commission has been given, or is about to receive, court-order DNS blocking powers; ISP blocking is not in operation as a current measure. A reader who sees an offer from an unlicensed site sees an offer that the Commission is actively trying to disrupt, and that should weigh on the decision to engage with it.

Frequently asked questions

How do I sign up for a betting site in Great Britain?

Pick a bookmaker licensed by the Gambling Commission and verified on its public register. Open the account with your real name, address and date of birth; the operator must verify these before you can deposit or gamble. Pass the verification check, make the minimum deposit the offer requires, place the qualifying bet at the offer’s minimum odds, and the free bets or bonus credit to your account within the operator’s stated window. Most operators credit free bets automatically; some require opt-in. The whole process takes minutes for the form and a working day or so for verification.

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

Ten times the bonus amount. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x. A £10 bonus at 10x requires £100 of qualifying bets; under the cap, no more. Bets must be at or above the offer’s minimum odds, typically 1/2 (1.5 decimal). Whether the cap applies to free bets with no wagering condition is not established in the published rule.

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

The minimum odds is the lowest price at which a bet counts toward clearing the bonus or unlocking the free bets. A minimum of 2.0 (1/1) means the selection’s odds must be 2.0 or higher; 1/2 means 1.5 or higher. The wagering requirement is the multiple of the bonus you must bet through. A 10x wagering requirement on a £10 bonus means £100 of qualifying bets at the minimum odds. Bets below the minimum odds do not count, and the offer’s expiry window sets the deadline for clearing.

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

Because that is the product. A free bet is a one-shot stake; if it wins, the operator keeps the stake and pays out the profit at the stated odds. A £10 free bet at 3/1 returns £30, not £40. The stake-not-returned model is the default across the UK licensed market. A small number of offers return the stake — some acca tokens, some sports bets — and those say so explicitly in the terms. The headline of an offer reads as cash; the small print says what the token actually is.

Can a sports betting offer be tied to a casino bonus under the Commission’s rules?

No. Since 19 January 2026 the Commission has banned mixed-product promotions: any offer that requires gambling on two or more product types such as betting and casino, betting and bingo, or betting and lottery. The example in the Commission’s guidance is “bet on football to get free spins”, which is now prohibited. A sports bettor cannot be pulled into a casino wallet as a condition of claiming a sports welcome. Operators continue to advertise their casino products on their sportsbook pages; the ban is on tying the offer, not on the cross-marketing.

How can I check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is the test. Search by business name, trading name, domain or licence account number; the register returns the entry, the licence categories and the licence holder. The licence numbers in the table earlier in this guide are the search terms. A bookmaker whose licence number does not return an entry on the register is not licensed, regardless of what its website says. A .com address does not on its own indicate offshore; licensed operators use .com and .co.uk. Northern Ireland has its own older law, and the Commission’s Great Britain licence does not regulate it.
