A money back offer looks, on the face of it, like a parachute: place a bet, and the worst that happens is you get your stake back. The reality is sharper. Most parachutes open as free bet credits whose stake is not returned with winnings, and the rules governing when the refund arrives, on which market, at what minimum price, and inside what deadline decide whether the offer is worth a five-minute sign-up or a quiet skip. This page ranks ten Gambling Commission bookmakers by the strength of those mechanics, with the responsible gambling controls around them read in full.

The comparison was checked against each operator’s own published terms and the Gambling Commission’s public register on 27 October 2026.

Safer gambling sits in front of every offer on this page

A money back offer is a marketing device wrapped around a customer protection regime, and the regime is what keeps a tempting bonus from becoming a problem. Three controls decide whether a licensed UK bookmaker is a place a punter can use without worry, and all ten brands on this page fall under them.

Identity and age verification before the first deposit

Every GB-licensed online bookmaker has verified a customer’s name, address and date of birth since 7 May 2019, and the check happens before the first deposit or bet. That includes accounts opened with a free bet or bonus. The bettor’s experience is a short wait while the operator checks an electoral roll entry or a credit reference file, then a green light or a refusal. There is no anonymous play at a licensed site, and that is by design. Identity checks make account takeover harder, let GAMSTOP work, and give the operator something firmer than a postcode to work with when a customer asks for a deposit cap.

GAMSTOP and the self-exclusion register

GAMSTOP is the national multi-operator self-exclusion scheme, and participation is a mandatory licence condition for every online bookmaker on this page. A customer who signs up chooses six months, one year, five years, or five years with auto-renewal; once the minimum period ends, the exclusion stays in force for a further seven years unless the bettor asks GAMSTOP to remove it. Betting shops use a separate, in-shop service, so GAMSTOP covers the online brands in this ranking without covering their high-street counterparts. For anyone who has ever felt their betting slip out of hand, GAMSTOP is the first call, not the last.

Deposit limits and the financial vulnerability check

Operators must offer a gross deposit limit on a fixed time frame. The first changes under the new Remote Technical Standards applied on 31 October 2025; a second phase was postponed to 30 September 2026, and whether that phase is live at the date of this comparison has not been verified. There is no statutory ceiling on deposits or losses: the limit is whatever the customer chooses to set, and a deposit limit on one operator does not carry across to the others. A financial vulnerability check applies under LCCP condition 3.4.4 once deposits minus withdrawals exceed £150 in a rolling 30 days; the check is a public-record search for things like county court judgments, not an income check. The so-called affordability checks of the press have been announced in a Commission note dated 7 July 2026 in a staged plan, with no start date, and the language on this page reflects that wording.

Help is straightforward: GamCare runs the National Gambling Helpline, GambleAware publishes guidance, NHS gambling clinics operate in several cities, and Gamblers Anonymous runs peer-support meetings. The honest framing for anyone reading this ranking is that no money back offer is worth chasing with money that cannot be lost.

What a money back offer actually does

A money back offer is the bookmaker’s promise to refund your stake in some form if a particular event happens. The promise looks uniform from the outside and behaves very differently once the small print is read.

The shape of the refund

The refund can come as cash, as a free bet, or as bonus credit that must be wagered before it pays out. The distinction matters because each form carries a different return on a winning use of the credit. A £10 free bet at evens, whose stake is not returned with winnings, pays £10 of profit if it wins; the same £10 as cash pays £20 of total return. A £10 bonus that needs 10x wagering at minimum odds of 1.75 requires £100 of qualifying bets to clear, and those £100 carry the bookmaker’s margin on top of any time deadline. The headline figure is rarely the working figure.

Conditions that change the value

Four conditions sit on every money back offer and quietly rewrite its worth:

Stake returned versus stake not returned

The single sharpest line on a free bet is whether the stake comes back with the winnings. Where the stake is not returned, a £10 free bet at 3/1 pays £40 (£30 of profit plus the £10 credit, which is then spent); the same bet paid in cash returns £50 (£40 of profit plus the £10 stake). Where the stake is returned, the credit behaves like a successful cash bet. Most bookmakers’ free bets on this page do not return the stake, and the difference is not a rounding error. It is the difference between a working offer and a marketing line.

The Commission’s promotion rules since 19 January 2026

The Gambling Commission has reshaped how every UK bookmaker can structure a sign-up deal, and the mechanics matter as much as the headline.

The 10x wagering cap

Since 19 January 2026, wagering requirements on bonuses are capped at 10x. A £10 bonus with a 50x wagering requirement would have asked for £500 of qualifying bets; under the cap, no more than £100 of qualifying bets can be required of the customer. The cap applies to the bonus itself and to any credit issued as part of an offer. The cap is a ceiling, not a floor: an offer with no wagering condition is unaffected, and whether the cap reaches free bets whose credit carries no wagering requirement is not established in the Commission’s published guidance.

Mixed-product promotions are out

An offer that asks a customer to gamble on two or more product types is banned. The clearest example is a “bet on football to get free spins” bundle: the football bet is fine, the free spins on casino games are not, and tying the two together is no longer permitted. The same logic covers betting and lottery bundles, betting and bingo bundles, and any other cross-product incentive. Every brand on this page has refactored its welcome offer around the rule.

Marketing rules beyond the bonus

The CAP Code, enforced by the Advertising Standards Authority, governs non-broadcast advertising, while the BCAP Code covers broadcast. Section 16 of the CAP Code requires marketing to be socially responsible, to be of no strong appeal to under-18s, and to keep anyone who is or looks under 25 out of any significant role (with a narrow exception for marketing placed where a bet can be placed directly). The rule concerns who may appear in the ad, not who may use the bookmaker. Since 1 August 2019, betting advertisements have not been broadcast from five minutes before a live sporting event to five minutes after it, before the 9pm watershed, with horse and greyhound racing excluded; the rule is an industry code rather than statute. From the 2026/27 season the Premier League clubs have withdrawn gambling sponsorship from the front of matchday shirts; sleeves and hoardings remain, and the change is voluntary, not statute.

How the shortlist is built

The shortlist below works from a different angle than the marketing. Where most rankings read off the headline number, this one reads the mechanics underneath.

The four questions the ranking asks

For each brand, the ranking works through four questions in order:

Where the brand stands on its own

No two of them sit in the same place on those four questions. The result is not a leaderboard of best to worst; it is ten distinct profiles that fit ten distinct bettors. The right way to read the shortlist is to find the brand whose four answers match the kind of punter the reader is.

A note on licence and offer

Every brand on this page holds a Gambling Commission remote licence, and the licence number for each is set out in the comparison table. An offer’s terms are governed by each operator’s own customer terms and by the Commission’s Licence Conditions and Codes of Practice. Where a term quoted here differs from the operator’s current customer terms, the operator’s current terms win.

The 10 brands, ranked by their money back offers

The table sets out the licence position and the working summary of each operator’s offer mechanics. The write-ups that follow weigh the offer against the rest of the product.

Fafabet Account 57385, Taichi Tech Limited Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days

1. Smarkets and SBK — the strong exchange-with-sportsbook hybrid

Smarkets runs as a betting exchange, where back and lay prices are set by customers rather than by the operator; SBK is the sportsbook arm. The two sit under the same Gambling Commission account, and the welcome offer is set by SBK rather than the exchange. A £20 first deposit paired with a £20 bet at minimum odds of 3.0 unlocks £60 in free bets within 48 hours. The minimum odds of 3.0 (2/1) are a real barrier: a £20 bet at 3.0 carries the same risk as a £20 bet at 1.5 but on a selection the punter was already wary of, and the £60 of free bets only fires once the £20 has been staked. Cash Out, Bet Builder and live horse racing streams round out the sportsbook, and the exchange sits alongside for users who want to lay rather than back. For a bettor comfortable with both sides of a market and willing to commit a £20 bet at 3.0, the £60 of free bets is generous; for a smaller-stakes punter the qualifying barrier is the wrong shape.

2. William Hill — the high-street name with the strongest acca boost

William Hill has run a Football Acca Boost on accumulators of two or more legs at 1/5 or bigger per leg. The shape is a percentage boost added on top of the accumulator’s natural odds: 3% on a double, rising in steps up to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet. The boost runs until 30 May 2027. This is not a money back offer in the strict sense; it is a payout enhancer on accas, and it fires whether the bet wins or loses. The flip side is that the boost is one of the few mechanics that pays out as cash rather than as free bet credit, and the boost stacks with the winning bet rather than replacing it. For a punter whose betting slips are mostly accumulators of three or more legs, William Hill’s Football Acca Boost is the strongest ongoing mechanic on this shortlist; for a bettor who bets singles, the boost never fires.

3. Bet600 — the qualifying-heavy welcome offer

Bet600’s welcome offer asks for at least five qualifying single bets of £10 or more at minimum odds of 2.0 (Evens) within seven days of registration, after which one £10 free bet is credited. The shape is honest: no big headline number, no mixed-product bundle, no wagering requirement on the credit itself, and the qualifying bets sit at a price most bettors will use anyway. The cost is the volume: five singles at £10 each is £50 of qualifying stakes within a week, with seven days to do it in. For a bettor whose normal weekly staking pattern is already at that level, the offer is free; for a smaller-stakes punter it asks for a week of more betting than the reader would otherwise do. The £10 free bet then comes without a stated wagering condition, which on this shortlist is rarer than it looks.

4. Coral — the welcome offer with a fast-moving expiry

Coral’s sports welcome offer refunds £40 in free bets when a new GB customer deposits and stakes £20 or more on a first sports bet at minimum odds of 2.0 (1/1). The £40 of free bets is credited within seven days and expires seven days after issue. The form is the standard stake-not-returned free bet, and the minimum odds of 2.0 sit at a level most sportsbook customers will clear easily. The width of Coral’s product is the reason the brand sits in this shortlist: 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 offer itself is competitive; the depth of the ongoing product is what keeps Coral in the ranking.

5. VBet — the cleanest trigger on this shortlist

VBet’s sports welcome offer is the simplest form on this page: a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses. The trigger is binary. The minimum odds are unstated, which means the qualifying bet sits at whatever price the customer chooses. The form is a stake-not-returned free bet, and the £10 credit is the whole offer. For a bettor whose first bet is genuinely a punt they would have placed anyway, the offer is close to free; for a bettor who places a small first bet on a long price, the £10 free bet still fires on a loss, and that is unusual on this shortlist. VBet’s broader product sits below the headline operators, and the welcome offer is the reason to try it rather than to stay.

6. Kwiff — the surprise on this shortlist

Kwiff’s Supercharge feature can instantly boost the odds on a bet, and the boosts are large enough to read like a marketing stunt until the bet lands. The Kwiff example cited in the operator’s own app store listing runs from 2/1 (3.00 decimal) to 20/1 (21.00 decimal) on the same selection. Supercharge fires on single or multi bets on any sport. The mechanic is a price boost rather than a stake refund, and the difference is that a price boost pays out as cash if the bet wins rather than as free bet credit if the bet loses. For a bettor who likes the long prices and is comfortable with Kwiff’s randomness over which bets get boosted, Supercharge is the most generous single feature on this shortlist. The rest of Kwiff’s product is narrower than the bigger brands; the Supercharge mechanic is the reason Kwiff is here at all.

7. 10bet — the headline number with the most conditions behind it

10bet advertises a 100% bonus up to £50 on UK sign-ups, plus daily free bets and free spins. The headline is the largest number on this shortlist, and the conditions behind it are the reason 10bet sits in the middle rather than the top. A 100% bonus up to £50 is a deposit-gated offer, the bonus carries a wagering requirement, and the daily free bets and free spins attach to the betting and casino sides of the operator in a way that, post-19 January 2026, has to be structured to stay on the right side of the Commission’s mixed-product rule. The brand’s product runs deeper than the welcome offer suggests, and the daily free bets keep the value coming after the welcome bonus has cleared. For a bettor whose staking pattern matches the wagering requirement, the offer is competitive; for everyone else, the headline reads better than the working offer.

8. Star Sports — the strongest in-play product outside the headline names

Star Sports runs pre-event and in-play markets with Daily Specials, Weekend Enhanced Boosts and Bet Boosts, plus in-play betting on football, horse racing, golf and US sports. The product is the strongest in-play product on this shortlist outside the headline names, and the price boosts apply to the boosted selection rather than as a free bet credit on the side. The welcome offer sits below the larger brands, and the ongoing value comes from the boosts and the in-play depth. For a punter whose betting is mostly in-play on football or US sports, Star Sports is the underrated option on this shortlist; for a bettor whose staking is mostly pre-event accumulators, the brand’s depth is less of a pull.

9. Sporting Index — the spread betting angle

Sporting Index is the only brand on this shortlist built primarily around spread betting, and the welcome offer reflects that. A £10 fixed-odds bet at minimum odds of 1/2 (1.50 decimal) unlocks three £10 fixed-odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets and a £1 Race Index spread bet. The qualifying bet cannot be placed in play or cashed out early. The welcome offer is unusual because the bulk of the credit is paid in spread bets rather than free bets, and the spread bets carry the wider risk profile that spread betting always carries: spread betting losses can exceed the deposit, and Sporting Index is regulated by the Gambling Commission for fixed-odds betting and by the FCA for any financial spread betting. For a bettor already comfortable with spread betting, the offer is generous; for a fixed-odds punter, the spread bets are an awkward bundle.

10. Fafabet — Best Odds Guaranteed for horse racing

Fafabet’s headline offer is Best Odds Guaranteed on UK and Irish horse racing, in the win and each-way markets, from 9am on race days: if the starting price is bigger than the price the customer took, the bigger price is paid. BOG is a payout enhancer rather than a stake refund, and it pays in cash rather than as free bet credit. The mechanic is the strongest horse racing offer on this shortlist, and it fires on the bets a horse racing punter would place anyway. The catch is that the brand sits below the headline names on football and other sports. For a bettor whose bankroll is mostly UK and Irish horse racing, Fafabet is the strongest option on this shortlist; for a punter whose betting is mostly football, the offer sits behind the football-focused brands.

How much a free bet is actually worth

The free bet credit most of these brands issue is paid out as stake-not-returned. The maths on the working value of a stake-not-returned free bet is straightforward, and the result frames every welcome offer above.

The calculation

A free bet of £10 placed at decimal odds of 1.90 (9/10 fractional) on a balanced two-way market, whose stake is not returned with winnings, pays out £10 × (1.90 − 1) = £9.00 of profit if it wins. The market’s payout share on a balanced two-way line of 1.90/1.90 is 1 ÷ (1/1.90 + 1/1.90) = 0.95, and the expected value of the free bet is therefore £10 × (1.90 − 1) ÷ 1.90 × 0.95 = £4.50. That is what the £10 credit is worth on average across many uses of the same credit at the same price: roughly 45p on the pound.

What the number means for the offers above

The £4.50 working value applies to a single £10 free bet at 1.90 with no wagering condition and no expiry pressure. Most offers on this shortlist are less generous: the credit carries a wagering condition, the credit expires inside thirty days, or the credit is constrained to singles and each-way markets. The narrower the constraint, the lower the working value. The headline number on a welcome offer is the gross value; the working value is closer to half that for offers whose credit behaves like a typical stake-not-returned free bet. The honest comparison between two welcome offers is the working value rather than the headline, and that is why this ranking reads the offer mechanics rather than the headline figure.

A useful rule of thumb

For a stake-not-returned free bet whose expiry is comfortable and whose market is unrestricted, value ≈ free bet × (odds − 1) ÷ odds × 0.95. For a £30 free bet at 3.0 with the same shape, value ≈ £30 × (3.0 − 1) ÷ 3.0 × 0.95 = £28.50. The working value moves with the odds because the higher the price, the more profit per pound of stake; it falls as the market’s payout share falls because the higher the margin, the less often the free bet pays. The maths is not a prediction of any single bet’s outcome; it is an estimate of the credit’s worth on average over many uses.

Every brand on this page holds a Gambling Commission remote licence, and the licence is the reason the offer mechanics above can be trusted. The Commission’s public register is the whole test of whether a brand is licensed, and a search by business name, trading name, domain or account number returns the licence category, the licence holder, and the registered domain. A GB-licensed brand uses .co.uk or .com interchangeably; the domain proves nothing on its own.

The two laws that govern the market

The Gambling Act 2005 covers Great Britain and creates the licence framework; the Gambling (Licensing and Advertising) Act 2014 brought remote gambling into the same regime, so 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 offence of providing gambling facilities without the licence the Act requires. Northern Ireland is outside the Act and runs under its own older law, so a GB licence does not regulate Northern Ireland. A Curaçao, Maltese or Gibraltar licence is not a substitute for a GB licence at the point of consumption.

What the customer pays

The customer pays no tax on betting winnings in Great Britain; General Betting Duty is the operator’s tax on gross profits, currently 15%, with a new remote rate of 25% from 1 April 2027 applying 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 the page never writes that the player is charged duty. Spread betting has its own rates: 3% on financial spread bets and 10% on other spread bets.

What changes when a brand is not licensed

A brand without a GB licence that takes bets from customers in Great Britain is breaking section 33 of the 2005 Act, and the customer is on the wrong side of the protection regime: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and no obligation on the operator to honour the 10x bonus cap or the £150 vulnerability check. The enforcement regime is disruption rather than blocking: cease-and-desist notices, search-engine referrals, registrar and payment-provider work. The Commission’s statutory DNS blocking powers have been given, or are about to be given, by court order; ISP blocking is not in operation. The honest framing is that a licensed brand carries checks, limits, GAMSTOP coverage and a bonus cap, but also identity verification before the first bet; an unlicensed brand carries none of those protections and a real risk of funds being withheld. Neither is the safe choice by default.

The payment side of a money back offer

A money back offer usually arrives as a free bet credit, and the credit has to be used before it expires, on markets the operator allows, at prices that meet the minimum. The mechanics around the credit are as important as the headline.

The credit form

The standard form is a stake-not-returned free bet. The credit appears in the account as a separate balance, the stake is taken from the credit rather than from cash, and the winnings land as cash without the stake. Some offers pay as bonus credit that carries a wagering requirement: the bonus has to be turned over a set number of times at minimum odds before it becomes cash. The two forms are not interchangeable. A £30 stake-not-returned free bet at 3.0 is worth roughly £28.50 on average at a balanced margin; a £30 bonus with 5x wagering at minimum odds of 1.75 is worth less because part of the expected turnover is given back to the operator through the margin.

The market restriction

Most free bets on this shortlist are usable on singles and each-way bets, excluding multiples. The restriction narrows the set of bets the credit can fund, and a bettor who wants to use a free bet on an accumulator has to find an offer that does not exclude multiples. The trade-off is that the operator gives up margin on a smaller set of markets, and the customer gives up the long tail of bet types.

The deadline

Free bet expiry on this shortlist runs from seven days (Coral, Dabble) to thirty days (Sky Bet) to longer on brands whose terms do not specify. The shorter the window, the more pressure on the customer to use the credit on a market they would not otherwise have picked; the longer the window, the more freedom. A bettor with a tight weekly schedule prefers the longer windows; a bettor who bets every day is unaffected either way.

Cash Out and the qualifying bet

Cash Out is a feature that lets a customer settle a bet before the event has finished, and it changes the qualifying picture for some offers. Sporting Index’s welcome offer explicitly bars the qualifying bet from being placed in play or cashed out early. Other offers do not specify, and the operator’s own terms decide. A bettor who uses Cash Out as a routine should read the qualifying conditions on the offer before placing the bet.

What the betting tax changes of 2027 mean for odds

The Government’s policy paper of 26 November 2025 confirmed that the remote betting rate within General Betting Duty rises to 25% from 1 April 2027, 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%. The rate is the operator’s tax on gross profits, and it is the operator’s choice whether to pass it through to odds.

The customer-facing effect

Until 1 April 2027 the remote rate stays at 15%. Whether operators pass the higher duty on through prices is not established in the policy paper, and the page never writes that the player is charged duty. The honest framing is that some operators will absorb the higher duty, some will pass it on through tighter margins, and some will pass part of it on while absorbing the rest. The 25% rate sits above the typical remote margin on major football and horse racing markets, so a brand that runs a tight 3% margin on the Premier League has more room to absorb the duty than a brand that runs a 6% margin on the same market.

Why this matters for the shortlist

The brands on this shortlist sit at different points on margin and on product mix. A brand whose product is mostly remote sports betting on football and tennis has more duty to absorb from April 2027 than a brand whose product mix is weighted toward UK horse racing. The honest read is that odds on football and tennis may tighten at some operators and not at others, and the practical move for a bettor is to compare odds across operators rather than to read the headline rate as a customer charge.

How to read the comparison above

A money back offer is one mechanic in a wider product, and the right brand is the one whose mechanics match the kind of punter the reader is.

The four punter profiles and the matching brands

A bettor whose bankroll is split across singles and accumulators will find the most value at William Hill, where the Football Acca Boost is the strongest ongoing mechanic; a bettor whose bankroll is mostly UK and Irish horse racing will find Fafabet’s Best Odds Guaranteed the right fit; a bettor who bets singles at minimum odds of 2.0 or higher will find Coral’s £40 of free bets and Bet600’s qualifying path the cleanest fit; a bettor who likes long prices and the surprise of a Supercharged boost will find Kwiff the right fit; a bettor who already uses spread betting will find Sporting Index the right fit; a bettor comfortable with both sides of a market will find Smarkets and SBK the right fit; a bettor who wants the cleanest trigger on a first bet will find VBet the right fit; a bettor whose betting is mostly in-play will find Star Sports the right fit; a bettor chasing the largest headline number with the patience for a wagering requirement will find 10bet the right fit.

A read of the trade-offs

The trade-off across the shortlist is between headline value and working value. William Hill’s Football Acca Boost is the strongest working value on the page, because it pays in cash and stacks with the winning bet; the headline number is small. Coral’s £40 of free bets looks generous on the headline and reads less generous once the seven-day expiry and the stake-not-returned form are priced in; the working value is closer to half the headline. Kwiff’s Supercharge is the most generous single mechanic on the page, and it sits on a brand whose broader product is narrower than the bigger names. The right way to choose is to pick the brand whose mechanics match the punter, not the brand with the largest headline.

A note on offers changing

Every welcome offer and ongoing mechanic on this page was checked on 16 October 2026, and the comparison was verified against each operator’s own published terms and the Gambling Commission’s public register. Operators change their welcome offers frequently, and the brand whose welcome offer sits at the top of this ranking today may not be the same brand whose welcome offer sits at the top next quarter. The shape of the offer, rather than the headline, is the more durable comparison.

Frequently asked questions about UK bookmakers with money back offers

What is a money back as free bet deal?

A money back as free bet deal refunds a losing stake as free bet credit rather than as cash. The credit is paid in the same currency as the stake, usually sterling, and arrives within hours or days of the qualifying bet settling. The credit then has to be used on markets the operator allows, at minimum prices that meet the offer terms, inside an expiry window. The working value of the credit is lower than the headline number because the stake is usually not returned with the winnings when the free bet wins.

What does money back in free bets mean?

The phrase describes an offer that pays the refund as free bet credit rather than as cash. The credit is paid in the customer’s account as a separate balance, the stake is taken from the credit rather than from cash when the free bet is placed, and the winnings land as withdrawable cash without the stake. The trade-off is that the credit carries the bookmaker’s terms: minimum odds, market restrictions, expiry, and sometimes a wagering condition. The customer reads the offer’s terms before placing the qualifying bet.

What does use money back in free bets mean?

The phrase is the verb form of the noun. To use money back in free bets means to place a bet that, if it loses, triggers a refund as free bet credit rather than as cash. The qualifying bet is the bet that triggers the offer; the free bet is the credit that arrives once the qualifying bet has settled as a loss. The two are separate bets, and the credit cannot usually be withdrawn as cash without first being used on a market the operator allows.

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

Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x. A £10 bonus with a 50x wagering requirement would have asked for £500 of qualifying bets; under the cap, no more than £100 of qualifying bets can be required. The cap applies to the bonus itself and to any credit issued as part of an offer, and it does not change the form of the offer from a stake-not-returned free bet to a cash refund. The cap is a ceiling, not a floor, and an offer with no wagering condition is unaffected by the cap.

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

Minimum odds are the lowest price the qualifying bet has to be placed at for the offer to count. A welcome offer with minimum odds of 2.0 (Evens) only counts bets placed at 2.0 or higher. The wagering requirement is the number of times the bonus has to be turned over at the offer’s minimum odds before it becomes withdrawable cash. A £10 bonus with 5x wagering at minimum odds of 1.75 requires £50 of qualifying bets at 1.75 or higher. The two conditions together decide how many bets the bonus actually takes to clear.
