The headline on a welcome offer is the easy part. £30 in free bets, £40 back, 100% a week back — those numbers are the marketing. The harder questions are what the offer actually pays when the bets land, what it costs to clear, and how long the bettor has to do all of it. Those are also the questions that decide whether an offer is worth the registration.

This page compares the free bet sign-up offers available to UK bettors in 2026 against the rules those offers now have to follow. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x and banned mixed-product promotions that tie betting to casino, bingo or lottery play. The cap applies to bonuses; whether it covers free bets with no wagering condition attached is not established. Those rules narrow the offer but they do not flatten the differences between operators, and the gaps in expiry, minimum odds, stake-not-returned and qualifying payment method decide the rest.

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

Responsible gambling before the offer

A sign-up offer is only as useful as the controls that sit beside it. Every operator on the Commission’s register is part of GAMSTOP, the national online self-exclusion scheme that has been a licence condition since 31 March 2020. Self-exclusion periods run six months, one year, five years, or five years with auto-renewal, and once the minimum term ends a further seven years of exclusion follows unless the customer asks GAMSTOP to remove it. A free bet does not stand outside that framework: the Commission’s identity-verification rules require name, address and date of birth before a first deposit and therefore before a first free bet.

What that means in practice is that signing up to chase a welcome offer is not anonymous. The form will not release a deposit button until the operator has checked identity documents. For anyone who has self-excluded, the offer is unavailable: GAMSTOP is checked at the point of registration, not at the point of withdrawal, and the registration itself is the breach.

The other routine is financial. Licensed operators now run a financial vulnerability check at a relatively modest spend level — when a customer’s deposits minus withdrawals pass £150 over a rolling 30 days — that pulls a public-record check (bankruptcy, county court judgments). It is not an income check and not a credit-reference check. Beyond that, financial risk assessments have been announced on a staged timetable with no confirmed start date, so any headline about “affordability checks in force” overstates where the regulation currently sits.

Help is free and out-of-band. GamCare runs the National Gambling Helpline, GambleAware funds treatment and research, the NHS runs a small network of gambling clinics, and Gamblers Anonymous runs peer-support meetings. These services are not part of an operator’s terms and they do not require an account to use. A bettor who feels the offer pulling them past a budget they had set should reach one of them before the next deposit. Limits are a customer’s choice, and an offer is not a reason to lift them.

What a sign-up offer actually is

A sign-up offer is a promotion attached to opening an account and placing a first bet. The four shapes the UK market actually uses are worth separating, because each carries a different cost.

A free bet is a fixed-value token — £5, £10, £30, £60 — credited after the qualifying bet settles. The stake of a free bet is usually not paid back with the winnings: a £10 free bet at decimal odds 3.00 returns £30 (the £20 profit only), not £40. That single rule is where most of the disappointment in welcome offers lives. A price boost or enhanced odds offer replaces the standard odds on a named market with a higher price for new customers. A deposit match credits a percentage of the first deposit as bonus funds, almost always with a wagering requirement attached. A risk-free or stake-back offer refunds the stake as a free bet (not cash) if the first bet loses, and is therefore a free bet in a different wrapper.

The Commission’s January 2026 rules reshaped two of those four. Wagering requirements on bonuses are capped at 10x, so a £10 bonus can require at most £100 of qualifying bets before it withdraws; the previous market regularly asked for 30x, 40x or 50x, which turns a bonus into a grind. Mixed-product deals that ask a customer to bet on football to qualify for free spins, or to deposit on casino to release a sports free bet, are out. The cap applies to bonuses; the position on free bets with no wagering condition is not established, so each operator’s terms remain the source.

The other rule a bettor should read first is the qualifying payment method. The Commission banned credit cards for gambling in Great Britain in April 2020 and that ban extends to credit-card-funded e-wallet top-ups. Most welcome offers now restrict qualification to a debit card, an instant bank transfer, or both — Apple Pay, Google Pay and Revolut Pay are accepted for deposits at many of the brands below but do not always qualify the offer. A bettor funding the account from a wallet that does not qualify will place a bet, see the offer disappear, and find out the hard way.

The minimum-odds clause

Almost every sign-up offer carries a minimum odds line. Coral and Unibet both set theirs at 2.0 (1/1) on the qualifying bet; Spreadex goes lower at 1/2; Hollywoodbets ties its stake-back to accumulators with combined odds of 4/1 or greater and at least three legs; Betboro requires each of at least three legs at 3/5 (1.60) or higher. The minimum odds filter is doing real work: a qualifying bet at 1/2 (1.50) returns 50p profit for every £1 staked, while a bet at 2/1 (3.00) returns £3 profit per pound, and the offer only fires if the bettor is willing to take the higher-volatility line.

Minimum odds also rule out certain market types by stealth. A heavily favoured favourite at 1/5 will not qualify a £10 bet on a Coral or Unibet offer; the bettor has to find something priced at evens or longer. For accumulator-driven offers the minimum applies per leg or to the combined price, and the difference matters: Hollywoodbets’ 4/1 is the acca price, while Betboro’s 3/5 is each individual leg.

Expiry and what happens afterwards

Free bet tokens expire. Sky Bet’s free bets last 30 days from credit, with the further restriction that they can only be used on single or each-way markets and not on multiples. Betway’s tokens run with a 1x wagering requirement at minimum odds of 1.75. Betway’s main welcome offer credits four £10 tokens, each with a 7-day expiry. Dabble’s £10 free bet has a 7-day expiry. Coral’s £40 in free bets expires 7 days after issue. Unibet’s £40 follows the same 7-day window. BoyleSports issues £20 in free bets on a £10 qualifying bet; the tokens themselves follow the operator’s general 7-day expiry. QuinnBet’s tokens are valid for 7 days from credit.

The pattern is consistent: most welcome free bets in the UK market in 2026 expire within a week of being credited. The standout is Sky Bet’s 30-day window, which is generous against the field; the cost of that generosity is the singles-only restriction. A token that is not used inside the window is forfeited, and there is no extension, no second email, no last chance.

Cash-out, bet builders, and what is not really “free”

Cash Out, Bet Builder, and price-boost features are not part of a sign-up offer; they are account features, present or absent. bet365, Unibet, Kwiff, Smarkets/SBK, DAZN Bet and Spreadex all run a Cash Out function on at least some markets. Bet Builder — let a bettor combine several markets from the same event into one bet — is available at bet365 (with the further Bet Builder+ extension), Unibet, Kwiff, Kwiff’s Bet Builder+ across different games, Smarkets/SBK, DAZN Bet and Swifty Sports in a “coming soon” state. BoyleSports offers Acca Insurance (a free bet refund if one leg of an acca lets you down) and Acca Loyalty; William Hill runs a Football Acca Boost paying up to 200% on 20-leg accumulators with a £10,000 maximum per online bet.

None of these features changes the value of a sign-up offer in money terms. A Bet Builder token does not appear on a welcome page, and the bettor who judges the offer by what they can do after the welcome has been claimed is judging a different thing.

How much a free bet is actually worth

A free bet whose stake is not returned has a value that depends on the price the bettor takes. The arithmetic is straightforward: a £10 free bet at decimal odds of 2.00 returns £20 (the £10 profit only). At decimal odds of 5.00 it returns £50. At decimal odds of 1.50 it returns £5.

Two things pull the value down for any bettor. The first is that no outcome is certain: a free bet at 5.00 wins one time in five on a fair line and loses four times in five. Across many bets at the same price, the expected return is the price-implied probability times the profit. The second is the bookmaker’s margin: every price on a sportsbook sits below a fair line by the overround, so the probability the bettor is being assumed to face is higher than the true probability.

For an illustrative two-way market priced 1.90 / 1.90 (9/10 each side), the payout share is roughly 1 ÷ (1/1.90 + 1/1.90), which works out to about 95% — and the margin, the slice the bookmaker keeps on every pound bet, is roughly 5%. A £10 free bet on a single selection at decimal odds 1.90 returns £9 if it wins, and on a true 50/50 outcome the expected value across many such bets is £9 × 0.5 = £4.50 before the margin, which falls to roughly £4.30 after it.

That figure is an average over many bets, not a guaranteed outcome for any one. A free bet at longer odds carries a higher possible return but a lower strike rate. A £10 free bet at 5.00 wins one in five on a fair line and pays £40, which gives an expected return of £8 against the £10 stake; a £10 free bet at 10.00 wins one in ten and pays £90, expected £9; the value is bounded above by the stake itself at infinite odds (you can never win more than the stake multiplied by the price, and the strike rate at longer prices collapses faster than the price grows). Stated as a band, a £10 free bet is worth roughly £4 to £9 of expected value on a typical market, with the lower end at short prices and the upper end at longer prices — and never more than the stake in expected terms on any single bet.

The point that follows is the one to keep. A free bet is a real discount on a first bet, but it is not a profit. It is the chance to place a bet with the bookmaker’s money, and the value of that chance depends almost entirely on the price the bettor picks and the market’s margin.

Top 10 sign-up offers: the comparison

The table below ranks the ten bookmakers by the headline value of the welcome offer, the qualifying conditions, and what the offer’s own terms state on free bets. Where two operators carry the same headline value, the tiebreaker is the breadth of the free-bet window — what it can be used on and for how long.

Spreadex stands out for two reasons. First, it is the only operator in this comparison whose free bets can be spent across fixed-odds and spread betting — a feature of a dual-regulated business (FCA for spread betting, Commission for fixed odds) that no other brand in the list replicates. Second, the £60 head is the largest in the table, but the qualifying bet window is 28 days rather than the standard 7, which means a bettor can wait for the price they want rather than chasing a price in a weekend. The cost is that spread betting losses can exceed the deposit, and a bettor moving a token into a spread market is accepting that exposure. Spreadex’s headline is generous for a fixed-odds bettor; the spread dimension is its own animal.

Hollywoodbets sits at the other end of the structure. It is a stake-back offer, not a matched offer: the first qualifying accumulator loses, and the stake is returned as a free bet of up to £30. The free bet itself follows the standard stake-not-returned rule, so a winning free bet pays profit only. The acca filter (3+ legs, combined 4/1, settled within 7 days) is doing real work — a single at any price will not qualify.

The mixed-product note on Octobet is worth pausing on. The Commission’s 19 January 2026 rules banned mixed-product promotions that require gambling on two or more product types; the offer as described pairs a sports free bet with a £10 casino bonus. Whether Octobet’s structure is the kind of offer the rule catches is a question of how the casino bonus is conditioned: a casino bonus that requires separate opt-in and separate play, rather than being triggered by the sports bet, is the kind of structure that survives. A bettor claiming Octobet’s offer should read the casino-bonus terms separately rather than assume the pair is interchangeable.

The bet credits that look identical across Betway, Coral and Unibet are not identical. Coral and Unibet both offer £40 in free bets on a £20+ qualifying bet at minimum odds of 2.0, with 7-day expiry and debit card or instant bank transfer. Betway credits £40 in four £10 tokens, each with a 7-day expiry and a 1x wagering requirement at minimum odds of 1.75. The 1x wagering is unusual — most free bets in the UK market do not carry a wagering requirement at all, and the £40 headline is closer in real value to Coral’s £40 or Unibet’s £40 than the structure suggests. A bettor who plans to use all four tokens inside a week at any price they like will not feel the difference; a bettor who plans to leave tokens in the account past day 7 will lose them.

Spreadex — the spread-betting dual-licence case

Spreadex is regulated by the FCA for spread betting and by the Commission for fixed-odds betting, and the welcome offer straddles both. A £60 free-bet bundle on a £10 fixed-odds qualifying bet can be moved into either side of the business. The fixed-odds side is conventional: minimum qualifying odds of 1/2, the qualifying bet must be placed within 28 days of account opening, and the tokens expire on the operator’s standard schedule. The spread-betting side is not conventional: spread betting losses can exceed the deposit, the markets are quoted differently from a sportsbook (a spread of 25-27 on a goals-corers market, for instance, rather than a decimal price), and the settlement is on the size of the spread rather than on a win/lose binary.

The dual-licence structure is the reason the headline is so much larger than the fixed-odds field: Spreadex can afford to credit £60 because the spread side carries a higher margin and a more demanding product, and the £60 is partly a hook into a part of the business where the bettor is on the wrong side of a market maker’s edge. For a bettor who treats the offer as a fixed-odds free bet at short prices on football, Spreadex is the best headline in the comparison. For a bettor drawn into spread markets for the first time by a token, it is a much worse deal.

The 28-day qualifying window is also worth noting: a bettor who opens an account but does not place the qualifying bet inside the month loses the offer without recourse. That is the longest qualifying window in the comparison, and it sets a deadline the other operators do not.

Coral — the established mid-market offer

Coral is one of the more established names on the Commission’s register, licensed through LC International Limited (which also runs Ladbrokes). The £40-on-£20 headline is identical to Unibet’s on its face; the difference is in what sits around the offer. Coral runs a daily Reward Shaker (a free game that pays free bets and other rewards to existing customers), an Odds Booster on hundreds of markets, and free-to-play games such as Football Super Series with a £10,000 jackpot. The bet builder is absent from the offer line, though the standard sportsbook offers a wide range of markets.

The payment-method rule is the practical snag: Coral’s offer must be qualified with a debit card or instant bank transfer. Apple Pay, Google Pay, Revolut Pay, Visa, Mastercard and several bank-based options are accepted for deposits, but the offer is gated. A bettor funding the account from a wallet that does not qualify will see the offer disappear on settlement of the first bet. Coral also runs the Bet and Get structure cleanly: deposit £20, place a £20+ sports bet at minimum odds of 2.0, and £40 in free bets is issued within 7 days, expiring 7 days after issue.

For a bettor who already uses Coral’s sportsbook and is willing to tie a £20 first bet to a market priced at 2.0 or longer, Coral’s headline is competitive and the existing-customer rewards make the second account useful past the welcome. For a bettor who wants to bet on something close to certainty, the 2.0 minimum rules out short-priced favourites entirely.

Unibet — the established mid-market offer, with the racing edge

Unibet has operated since 1999 and its UK site is run by Platinum Gaming Limited, Gibraltar, under Commission account 45322. The headline matches Coral (£40 in free bets on a £20+ bet at minimum odds of 2.0), with the same 7-day expiry from issue and the same debit-card-or-instant-bank-transfer qualifying condition. The product around the offer is wider than Coral’s: Unibet runs 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 racing-side feature matters if the bettor bets on horses. Best Odds Guaranteed pays the bigger of the price taken and the starting price if the bet is placed after the day’s card is published, which is a structural advantage on race days when the early price drifts. Combined with the 7-day expiry on free bets, a Unibet free bet is a useful tool for finding a price on a horse the bettor fancies between offer credit and the next meeting.

For a bettor who bets on football only, Unibet’s offer is interchangeable with Coral’s. For a bettor who bets on horses as well, Unibet is the better choice on the offer plus the racing-side features, and the £40 token can be deployed on a horse with BOG protection rather than a football singles market with no such safety net.

Betway — the four-token structure with 1x wagering

Betway’s headline is £40 in free bet tokens, but it arrives as four £10 tokens rather than a single £40 credit. Each token carries a 7-day expiry and a 1x wagering requirement at minimum odds of 1.75. The qualifying bet is a first bet of £10+ at minimum odds of 2.0, with debit card deposits only.

The 1x wagering requirement is the rule that separates Betway’s tokens from Coral’s and Unibet’s. A £10 token at minimum odds of 1.75 returns £7.50 if it wins, and the 1x turnover means the £7.50 has to be staked again at minimum odds of 1.75 before withdrawal. The cost is small (£7.50 of qualifying bets at 1.75 to release £17.50 of winnings), and on a market with a typical 5% margin the expected cost is well under £1 per token. But it is a constraint that does not exist on Coral or Unibet, and a bettor who plans to leave winnings in the account without re-staking will find the withdrawal blocked until the turnover is complete.

For a bettor who bets regularly enough to clear four tokens inside a week at 1.75 or longer, Betway’s headline is competitive. For a bettor who plans to use one token and walk away, the structure is four small offers rather than one large one, and the qualifying conditions apply four times.

BetGoodwin — the racing-rooted £15 in three tokens

BetGoodwin is a Goodwin Racing product, and the racing roots show in the welcome structure. The headline is £15 in free bets made up of a £5 sports bet, a £5 acca and a £5 Sub-Cover bet (a racing-side free bet on selections the operator names). The qualifying bet is £10 or more. The token-level structure matches Betway’s four-tokens pattern, but the value is lower and the products are split across sportsbook, accumulator and racing.

The bettor who bets on horses will recognise Sub-Cover as a useful product for the days when the operator names a horse that needs a result. The bettor who bets only on football will find one of the three tokens useless to them. For the £15 headline BetGoodwin is the smallest offer in the table, and the £10 qualifying bet is the smallest real spend per pound of bonus — but the racing-side structure means the offer is genuinely different from Coral or Unibet’s £40, not just cheaper.

Betboro — the matched free bet up to £25

Betboro’s offer is a 100% matched free bet of up to £25 on the first qualifying wager. The match is on the first bet’s stake: bet £25 and receive £25 in free bets if the qualifying bet loses. The qualifying bet is £5 to £25 with at least three selections each at 3/5 (1.60) or higher, and a debit card deposit of at least £10. The free bet follows the standard stake-not-returned rule, so a winning free bet pays profit only.

The acca filter is tighter than Hollywoodbets’: each leg must be at 3/5 or higher, while Hollywoodbets requires combined acca odds of 4/1. A three-leg acca at 3/5 each leg has combined odds of roughly 3.5/1, which clears the Hollywoodbets combined-odds rule but each leg is short and the offer protects the stake on a structure that already has a higher strike rate than a long-shot acca. The matched-free-bet structure is closest in spirit to Hollywoodbets’ stake-back, with the difference that Betboro matches the stake as a free bet if the first bet loses, regardless of acca structure, while Hollywoodbets pays the stake back only on a 3+ leg acca at combined 4/1+.

For a bettor who wants a matched free bet with a wide qualifying bet structure, Betboro’s offer is broader than Hollywoodbets’. For a bettor who wants to back a single at any price, neither offer qualifies.

Hollywoodbets — the stake-back on a losing acca

Hollywoodbets’ sports welcome offer is the clearest stake-back structure in the comparison. New players who deposit £10 or more by card get their stake back as a free bet of up to £30 on their first qualifying losing accumulator (stake £10+, 3+ legs, combined odds of 4/1 or greater, settled within 7 days). One free bet per customer, and the free bet itself follows the standard stake-not-returned rule.

The structure is honest in a way most welcome offers are not. The marketing “stake back” is what it says: a free bet if the first acca loses, no free bet if it wins. There is no matched-free-bet gimmick, no wagering requirement, no minimum odds on the free bet itself beyond the operator’s standard. The 4/1 combined odds filter rules out short-priced accas (a 3-leg acca at 4/5 each leg sits around 3.5/1 and does not qualify). The 7-day settlement rule is tight: a leg voided or postponed can push the acca past the 7-day window and the offer falls away.

For a bettor who already backs accumulators, Hollywoodbets’ offer is the cleanest insurance-style welcome in the comparison. For a bettor who backs singles or short accas, the offer is invisible.

BoyleSports — the £20 headline with the Acca Insurance ecosystem

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed (€30 in free bets for a €10 bet for Irish players). The Acca Insurance offer sits beside it: opt-in, £5 minimum stake, minimum odds of 1/2, maximum refund of £20 as a free bet expiring in 7 days, bets placed and settled on the same day. Acca Loyalty sits on top of that: opt-in, £5 minimum stake, minimum combined odds of 3/1, 5 or more settled legs, free bet expiring after 7 days.

The headline is smaller than Coral or Unibet but the supporting ecosystem is meaningful. A £20 refund as a free bet on a losing acca, capped at £20 per acca but available as a routine insurance product, is a structural protection for an acca bettor that no other operator in the comparison offers as cleanly. The cost is the same-day settlement rule: an acca leg voided or postponed past the day can disqualify the refund.

For an acca bettor who would buy acca insurance anyway, BoyleSports’ headline is the best ecosystem in the comparison. For a singles bettor, the headline is a small £20 and the supporting ecosystem is irrelevant.

Betway, Coral, Unibet, Spreadex — what the regulators see

Every brand in this comparison holds a remote operating licence from the Gambling Commission, and every brand is on GAMSTOP. The Commission’s public register is searchable by business name, trading name, domain or account number, and a brand’s presence on it is the test of whether it holds a licence. Several brands can run under one licensee — Coral and Ladbrokes are both under LC International Limited, for example — and that shared licence is part of why Coral’s offer structure is closer to Unibet’s than to a small independent brand’s.

Licence categories matter for what the operator can offer. Remote general betting standard (real events) covers fixed-odds betting on real sporting events; remote betting intermediary covers betting exchanges; remote general betting standard (virtual events) covers computer-generated events; remote pool betting covers pool products. Spreadex’s FCA authorisation for spread betting is separate from its Commission licence and the £60 free-bet bundle straddles both. A bettor on an offshore site that holds only a Curaçao or Maltese licence has no Commission protection: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no £150 vulnerability check, no 10x bonus cap. The honest framing is that licensed = checks, limits, GAMSTOP and the bonus cap; unlicensed = none of those protections and possible loss of funds.

The legal frame around an offer

The Gambling Act 2005 is the statute that licenses the UK commercial market. The Gambling (Licensing and Advertising) Act 2014 extended it so that an operator using remote facilities in Great Britain needs a Commission licence wherever it is based; a Gibraltar or Maltese licence is not a substitute. Northern Ireland is outside the 2005 Act and has its own older law, so a GB licence does not regulate Northern Ireland.

The minimum age is 18, and identity verification (name, address, date of birth) is required before a customer can deposit or gamble — and that includes before a customer can use a free bet. The credit-card gambling ban (in force since 14 April 2020) covers credit-card-funded e-wallet top-ups as well as direct card transactions. The 19 January 2026 promotion rules cap wagering requirements on bonuses at 10x and ban mixed-product promotions tying betting to casino, bingo or lottery play.

The player pays no tax on betting winnings in Great Britain (this is general information, not tax advice; a professional gambler should ask HMRC or an adviser). General Betting Duty is the operator’s tax, currently 15% on gross profits; 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%. Whether operators pass duty on through odds is not established, and it is not written that the player is charged duty. Until 1 April 2027 the remote rate stays at 15%.

Advertising is not licensed by the Commission; it runs through the CAP Code (non-broadcast) and BCAP Code (broadcast) enforced by the ASA, alongside the Commission’s marketing conditions. CAP Code section 16 requires marketing to be socially responsible, not of strong appeal to under-18s, and not to feature anyone who is or seems to be under 25 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.

Where the page stops and what to check on the day

Every operator in this comparison is licensed by the Commission, and every operator’s offer structure has been drawn from the brand’s own published terms as of the date at the top of the page. Offers change. Welcome headlines change with promotions, minimum odds are revised when a brand updates its terms, payment-method qualifiers change when a new payment provider is added or removed, and the Commission’s rules continue to evolve. A bettor who has found an offer they want to claim should re-check three things on the brand’s own terms page on the day they register: the qualifying payment method, the minimum odds on the qualifying bet, and the expiry on the free bet. Those three lines decide whether the headline the user clicked is the offer the user gets.

A licence check is the other step that pays off. The Commission’s public register is searchable by brand name, trading name, domain or account number. A brand that holds a GB remote licence is on it; a brand that does not is not on it. For an operator offering betting to a UK customer, presence on the register is the only test that matters; the domain (.com or .co.uk) proves nothing.

Frequently asked questions about free bet sign-up offers

How does a bettor sign up for a betting site in Great Britain?

Pick a brand licensed by the Gambling Commission (the Commission’s public register lists every holder), then open an account with name, address and date of birth. The operator is required to verify identity before the first deposit, so a driving licence or passport and a proof of address are usually requested. Once verification is complete, deposit by debit card or instant bank transfer, place a qualifying bet at the minimum odds the welcome offer sets, and the free bet is credited when that bet settles.

How is a sportsbook different from a betting site?

A sportsbook is the part of a betting site that takes fixed-odds bets on real sporting events. Most UK betting sites also carry a casino, a live casino, a bingo room or a poker room under the same licence, but a sportsbook is a separate product with its own markets, odds and bonuses. The Commission’s mixed-product promotion rules (in force since 19 January 2026) prevent a sportsbook offer from being conditioned on casino, bingo or lottery play, so a free bet credit on a sportsbook stays a sportsbook credit.

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

10x. The Gambling Commission’s promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x the bonus amount, so a £10 bonus can require at most £100 of qualifying bets before it withdraws. The cap applies to bonuses; the position on free bets with no wagering condition is not established, so each operator’s terms remain the source on that point. Mixed-product promotions that tie betting to casino, bingo or lottery play 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 counts toward the offer. A 2.0 minimum rules out anything shorter than evens; a 1/2 minimum rules out only very short favourites. The wagering requirement is the number of times the bonus (or sometimes the bonus plus deposit) has to be staked before the bonus and winnings become withdrawable. A 10x cap on bonuses means a £10 bonus can require at most £100 of qualifying bets at the minimum odds. A minimum-odds clause is a filter on the qualifying bet; a wagering requirement is a filter on the bonus itself.

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

A free bet is a token, not a stake. A £10 free bet at decimal odds of 3.00 returns £30 if it wins — the £20 profit only, not the £30 (£10 profit plus the £10 stake). The stake is the bookmaker’s, and the winnings are profit on it. That rule is the single largest source of disappointment in welcome offers, and a bettor who plans to claim several welcome offers across several brands should expect every free bet to follow the same structure unless a brand’s terms say otherwise.

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 that require gambling on two or more product types — betting, casino, bingo and lottery — as a condition of a single offer. An offer that asks a customer to bet on football to qualify for free spins, or that ties a sportsbook free bet to a casino deposit, is not allowed. A casino bonus offered alongside a sportsbook welcome, with separate opt-in and separate qualifying conditions, is the kind of structure that survives; the test is whether the sportsbook offer stands alone.
