Money-back offers, decoded: what UK bookmakers actually give you
Available in USRead any gambling ad in Britain and “money back” does a lot of work. A bookmaker pushes a promotion in a flash on the side of a Premier League pitch, the punter sees the promise, and the small print carries the conditions that turn the gift into a grind. This page works through the substance behind those words – what a money-back as free bet deal actually delivers, where the wagering requirement sits in the new rule book, which operators publish what kinds of refund, and how a calculation translates the marketing claim into the figure a bettor might clear. The angle throughout is consequence: not what an offer says on the box, but what it puts in the account when the dust settles.
Current as of 27 October 2026. Licence figures verified against the Gambling Commission’s public register.
How a “money-back” promotion actually works
A money-back offer is an insurance policy the bookmaker writes on its own terms. The customer places a bet under stipulated conditions. If those conditions hold and the bet wins, nothing special happens – the book pays the normal return. If the bet loses, the book refunds the stake in one of a small number of forms: as a free bet, as a bonus balance, as cash, or as a combination of these. None of those four are the same thing, and the difference between them is what the promotion is worth.
Take the most common case, the “money back as a free bet” deal described in, and. The bettor wagers £10 on a first bet. If the selection wins, the bettor keeps the winnings in the usual way. If it loses, the book credits £10 (or a similar figure) into the customer’s account as a free bet – meaning a token that can be wagered once, whose stake is not returned if that subsequent bet wins. A £10 free bet placed at evens (decimal 2.00) and won settles at £10 in profit, not £20. The distinction between a refund as cash and a refund as a free bet is the difference between getting £10 and getting roughly £8 of expected value on the same lost stake, which is the calculation set out later in the page.
The promotion is sold as refund-on-loss protection, and the protection it sells is genuinely narrower than the marketing suggests. The qualifying bet must meet a minimum odds threshold – Evens (2.0) at Coral, 3.0 for Smarkets/SBK – and an each-way or multiple bet is often excluded. The refund must be claimed within a window – seven days at Coral, seven days at Bet600, 30 days at Sky Bet. Refunds frequently exclude certain markets (virtuals, system bets), are paid as free bet tokens rather than cash, and never apply to stakes placed with a previous free bet or bonus.
Free-bet tokens are the home currency of UK money-back offers. A free bet carries restrictions of its own – minimum odds for the next wager, expiry, market exclusions, no partial cash-out – and it never pays the stake back with the winnings. The mechanics are blunt in the small print. They are also the reason the headline price of a free bet is not what the bettor keeps.
The shape of the UK money-back market
The set of operators covered below is a licensed cross-section of the British online betting market, drawn from the Gambling Commission’s public register rather than from the marketing departments of the brands themselves. Every one of them operates under a Commission licence for either remote general betting (real events) or remote betting intermediary (the exchange category), and every one is registered with GAMSTOP by virtue of that licence.
The cluster reveals three broad groupings. The first is the established high-street names – William Hill and Coral among them – whose welcome offers sit in the £20-£40 bracket and whose terms reflect a generation of dealing with the Commission’s social responsibility code. The second is the operator-app newcomers – Bet600, VBet, Kwiff, 10bet – whose welcome offers have been redesigned around smaller, sharper triggers (a £10 refund at VBet, an acca insurance-style trigger at 10bet ) aimed at converting app-store traffic rather than rewarding a long-tenured customer. The third is the specialist shops – Smarkets/SBK at the exchange end, Sporting Index in spread betting, Star Sports in independent high-street racing – whose welcome offers reflect each firm’s particular product line. The exchange welcome can be aggressive in nominal terms (£60 in free bets at Smarkets/SBK ) because the matching model tolerates bigger sign-on sweeteners than a traditional bookmaker’s risk desk does.
Within those groupings, the welcome offer is rarely a pure “money back if you lose” structure any more. It is more often a free-bet cluster gated on a qualifying wager – £20 in at Coral for £40 of free bets, 5×£10 qualifiers at Bet600 for one £10 free bet, £10 in for £10 back at VBet. The “money back” label survives as a brand promise; in product terms it has been re-engineered into a free bet credit on settlement. The audit that catches the gap between the two is the wagering rule that took effect across the market in January 2026.
The new UK rule book: what changed on 19 January 2026
The Commission’s promotion rules, in force since 19 January 2026, redrew two lines that bookmakers had been close to for years. The first is a hard cap on wagering requirements: no licensed operator may attach a wagering multiplier above 10x to a bonus or free bet that the customer has to clear before withdrawing. The second is a ban on mixed-product promotions – any offer that requires the customer to stake on more than one product type, such as “bet on football to unlock free spins” or “place a sports bet to receive casino bonus credit.” Both rules apply to every operator licensed by the Commission; they apply to free bets only when a wagering condition is attached, and the rule does not say whether a “free bet with no clearing requirement” is itself subject to the 10x cap when the customer’s only further action is to use the token and withdraw winnings. That gap is not resolved in the public materials available; readers should not assume either answer.
A wagering requirement of 10x means that a £10 bonus, if cleared at the maximum permitted multiplier, demands £100 of qualifying bets before withdrawal. A £10 free bet with a 5x turnover triggers £50 of qualifying stake. The cap is the headline figure; its real consequence is that bonuses sized larger than the average UK free bet still clear in a manageable number of wagers, and bonuses that were marketed under 50x, 60x or even higher turnovers in unlicensed settings are not lawful to offer at a GB-licensed brand. The bettor’s gain is a ceiling they can verify. The bettor’s loss is the underwater conditions – minimum odds on each clearing bet, capped stakes during the rollover, a market list that excludes the deepest-margin wagers – that the operator uses to defend its margin inside the cap.
In-play markets at licensed operators remain unrestricted under the rule change, which is something worth saying plainly because the question of in-play access is one of the commonest search-terms on the topic. There is no statutory live-betting cap, no Government-set stake ceiling, no per-event wagering limit. Sports and virtuals each carry their own licence category under the Act, and a real-events licence does not extend to virtuals without a separate entry on the register.
What a money-back offer costs the operator and what it is worth to the punter
A bookmaker’s margin sits inside every price on the betting board, and the margin is what a money-back offer costs the operator in expectation. The arithmetic is plain: for every unit staked on a market, the operator returns the gross payout share and keeps the difference. On a two-way market priced 1.90/1.90 in decimal (9/10 each side in fractions), the payout share is the reciprocal of the sum of the implied probabilities.
For odds of 1.90 each side: 1/1.90 + 1/1.90 = 0.5263 + 0.5263 = 1.0526. The payout share is 1 ÷ 1.0526 ≈ 0.95, or roughly 95%. The margin is therefore around 5%, which is the bookmaker’s expected take from a unit bet on that market before any refund or bonus logic is layered in.
The free bet that follows from a money-back deal is shaped by that margin, because the punter’s expected value of the token is the size of the token times (odds − 1) divided by odds, scaled by the payout share of the market on which it is used. For an illustrative £10 free bet placed at decimal odds of 1.90 (9/10 fractional): (1.90 − 1) ÷ 1.90 = 0.4737. Multiplied by the £10 token, that is £4.74; multiplied by the 95% payout share of the market, that gives an expected value on average of around £4.50. That figure is an average over many bets and across a balanced book – the punter who wins at long odds and picks high-margin events does better or worse than that figure, while the punter who uses the token on a heavily juiced market does noticeably worse.
The calculation is presented as a band rather than a single figure because no sensible answer sits at one number. Place the £10 free bet at decimal odds in the 1.50-2.50 range – which is where most minimum-odds requirements in UK offers force the punter to play – and the expected value spans roughly £3.30 to £5.50 at a 5% market margin. The shape of the offer and the shape of the bettor’s market choice both move the result, and a refunder who treats the token as a certain win will miscalculate its actual worth.
The principle generalises to every free bet on this page. A token whose headline value equals the refunded stake is, on expected value, worth a fraction of that nominal figure once the stake-not-returned condition and the market’s margin are laid against it. The marketing holds out the nominal. The arithmetic gives the realised number.
What the Gambling Commission’s social responsibility code asks of these operators
The code that governs how licensed bookmakers treat customers sits in the LCCP (Licence Conditions and Codes of Practice). It is the same code that prescribes the GAMSTOP requirement, the financial vulnerability check at £150 of net deposits in a rolling 30-day window, and the 10x bonus cap already mentioned. It also sets a minimum age of 18 for any gambling activity and requires that a customer’s name, address and date of birth are verified before the first deposit – which means the “money-back” welcome bonus at a GB-licensed operator is claimed only after identity checks have cleared, and the bonus terms sometimes cite the verification as part of the qualifying process rather than as a separate step.
The financial vulnerability check applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days; it is a public-record review (for example, bankruptcy or county-court judgment searches), not a credit-reference check or an income check. Financial risk assessments, also known in the press as affordability checks, are announced in a staged plan (a Commission article of 7 July 2026), with no start date – write “announced, staged, no start date”, never “in force”. Deposit limits (RTS 12) require operators to offer a gross deposit ceiling on a fixed time frame; the first changes applied from 31 October 2025, with a second phase postponed to 30 September 2026 – whether it is live in its final form is not established from the public materials available.
GAMSTOP itself is the multi-operator self-exclusion scheme every online bookmaker in the covered set belongs to. Periods are six months, one year, five years, or five years with auto-renewal; after the minimum period, the exclusion remains in force for a further seven years unless the customer asks GAMSTOP to remove it. The service covers online sites and apps; betting shops use a separate scheme. Anyone self-excluded through GAMSTOP cannot trade a money-back offer or any other promotion at any participating operator.
Player protections beyond the Commission code are operated by third parties – GamCare runs the National Gambling Helpline, GambleAware funds treatment and research, the NHS operates gambling clinics, and Gamblers Anonymous runs peer-support meetings. These are the entry points for a bettor who wants to set a deposit ceiling, take a break, or step back from gambling entirely.
The mechanics of “money back as free bet” at the operators featured below
The free-bet refund is a recognisable shape across the British market. It works as follows in the typical configuration: a new or existing customer places a qualifying bet – usually a single, usually above a minimum price, often excluding multiples and virtuals – and if the bet loses, the operator credits free-bet tokens or a bonus balance to the customer’s account. The qualifying bet is normally a first bet, a first settled bet, or a first settled bet of a stated size.
The qualifying price sits at 1/2 (1.50) in some offers, at 1/1 (2.00) at Coral, at 3.0 at Smarkets/SBK, at 2.00 at VBet. The thresholds line up with the operator’s market position: a higher minimum price filters out the safest bets and protects the bookmaker from predictable qualifying wagers. The expiry sits at 30 days at Sky Bet and seven days at Coral and Bet600; a tighter expiry reduces the proportion of unused free bets that have to be honoured.
The stake-not-returned feature is universal among the operators’ free bets. None of the covered operators pays the free-bet stake back with a winning free-bet wager, and the customer-protection features universally available – GAMSTOP membership, the 10x cap, the verification gate – all sit on top of that loss-of-stake rule rather than compensating for it. Bonus money refunded in a different form – for example, a stake-matched bonus balance rather than free-bet tokens – is settled against a wagering requirement, and the wagering requirement is the lever the operator uses to recover the refund’s effective value to within the 10x cap.
The operators: licence, terms, and judgement
What follows is a licensed-by-licensed pass through the ten featured brands. Each entry names the Commission’s account number and the holder on the register, states the operator’s own published terms on money-back welcome offers, and closes on a verdict that takes a position on where the offer is worth taking and for whom. Two brands in the list – Kwiff and 10bet – use money-back mechanics less prominently than the others; their entries cover their welcome terms and the broader refund structure rather than the welcome bonus alone. The order below is not an editorial ranking.
Smarkets / SBK
Smarkets and SBK run as two faces of the same firm under Commission account 39173, with Smarkets operating the exchange and SBK the sportsbook on a single licence. SBK’s UK welcome offer is a £20 first deposit paired with a £20 bet at minimum odds of 3.0 – a notably high threshold in this market – which unlocks £60 in free bets within 48 hours. The same single licence carries SBK’s product line: Cash Out, a Bet Builder, and live horse racing streams.
The 3.0 minimum is the most distinctive feature of the SBK offer. Most competitors’ welcome offers start at 1.50 to 2.00; SBK’s threshold is high enough that qualifying bettors self-select as people with a strong opinion on a short-priced favourite, which in turn makes the bet-to-free-bet conversion pool more aggressive on the offer’s side. The 48-hour issuance window is short, the free-bet tokens are the standard non-stake-returned form, and there is no wagering requirement attached – so the post-bonus turnover does not run up against the Commission’s 10x cap at the level of the operator’s own design. The firm’s identity as an exchange operator carries through into SBK’s risk management: orders fill at the published price rather than being struck against a bookmaker’s house margin, and a punter who understands backing and laying will see a different rate from a punter who treats SBK as a traditional book.
The verdict is that SBK is the strongest money-back-style welcome on the covered set in nominal terms, but it is also the one that demands the most from the bettor’s reading – the qualifying threshold of 3.0 filters casual customers and rewards players with a view on a market that the exchange market is going to settle close to. A casual reader of the headline will pass on it; a market-aware reader will recognise that £60 of free bets with no attached wagering requirement is close to the most generous unrestricted welcome in the set.
William Hill
William Hill operates under Commission account 39225 as WHG (International) Limited, listed for remote general betting (real events). The firm’s football acca-insurance product runs on accas of two or more legs with each selection at 1/5 (1.20) or bigger, with the boost scaling from 3% on a double up to 200% on 20 or more legs, capped at £10,000 of additional payout per online bet, and running until 30 May 2027.
That product is an accumulator boost, not a money-back refund, and it illustrates how the “money back” label can mean different things across operators. William Hill’s acca insurance is paid on a winning bet, not a losing one, and it boosts a return by a percentage that depends on the number of legs. The maximum £10,000 cap is the kind of ceiling that protects a high-end firm from a freak payout on a multi-leg acca while still making the product feel generous. The product is not a money-back offer – a reader who reads “money back” into a successful accumulator boost has misread the structure – but it sits on the same shelf as one for the customer who uses it.
The verdict is that William Hill’s welcome products are built for acca-bettors rather than for the single-bet welcome market. A bettor whose weekly stake is on a three-fold football accumulator will see the boost ladder at work; a bettor who bets singles will not. The promotion is not advertised as a money-back deal at all, and reading it through the lens of this page rather than the firm’s own product page will mislead the comparison.
Bet600
Bet600 operates under Commission account 44731 as Tyche Tech Limited for remote general betting. Its welcome offer requires at least five qualifying single bets of £10 or more at Evens (2.0) or greater within the first seven days of registration, after which one £10 free bet is credited.
The five-bet qualifier is the defining feature. It is a multi-step qualifying process – five separate settling bets at a stated minimum, each at minimum odds – which is closer to a turnover requirement than a one-stake refund. The one-credit payoff at the end is a £10 free bet whose value, on the calculation above at a 5% market margin, is roughly £4.50 of expected value on average. The qualifying turnover is much higher than the payoff, with the implication that the offer rewards a bettor who would have placed those bets anyway and who uses the offer as a bonus on top of normal play, not as a one-off welcome gift.
The verdict is that Bet600 is the offer for the high-frequency single-bet bettor rather than the casual welcome-bonus hunter. Five £10 singles at 2.00 within seven days requires roughly £150 of stake, more than double the £40 typical welcome-brand qualifier, and the offer is closer to a turnover booster than to a money-back refund. A bettor whose natural betting rhythm is multi-single weekly will see it as a free £4.50; a casual bettor who forces five qualifying bets into a week is paying full margin on stake they would not have placed.
Coral
Coral operates under Commission account 54743 as LC International Limited for remote general betting and remote betting intermediary. The sports welcome offer is “Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within seven days and expiring seven days after issue, for new GB customers who opt in.
The offer is in the middle of the market. The qualifying threshold of 2.0 is the conventional midpoint. The £40 of free bets versus a £20 qualifying bet is a 2:1 face-value ratio. The seven-day expiry inside the seven-day crediting window is tight – a bettor who is in a different sport for a fortnight will see the tokens lapse. The firm publishes additional money-back mechanics beyond the welcome: a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games including Football Super Series with a £10,000 jackpot.
Coral’s welcome offer must be qualified with a debit card or instant bank transfer; the site lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options. E-wallet methods are present, but the qualifying route is restricted – a bettor who plans to deposit via Skrill or Neteller is unlikely to qualify for the welcome. The credit-card ban for gambling in Great Britain that took effect on 14 April 2020 covers credit-card-funded e-wallet transactions as well, though it does not affect debit-card or bank-based routes.
The verdict is that Coral sits as the conventional money-back-shaped welcome on the covered set, with a face-value ratio that does not stand out and a qualifying structure that most casual bettors can clear inside a week. The free-bet expiry is the main cost – a year-long punter will see this as a small factor, a once-a-year punt-taker will see a meaningful proportion of the £40 expire. For a casual UK bettor in 2026 the offer is workmanlike and not exceptional; for a bettor who keeps a steady weekly stake on singles it is a useful steady-state welcome rather than a one-off.
VBet
VBet operates under Commission account 44662 as SCGO Limited for remote general betting. Its sports welcome offer is a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses. The structure is a textbook money-back-as-free-bet welcome and one of the closest on the set to the marketing label.
A £10 refund on a £10 losing bet is the simplest expression of the deal – and the simplest to read. The face value of the refund equals the stake, the qualifying threshold is “any losing first bet”, and the refund is paid as a single free-bet token whose nominal value is £10. The free bet’s realised value on a 5% margin market at 1.90 is around £4.50; that is the number a bettor who loses the first bet will see in their wallet after the stake and the free-bet turnover are settled, not the £10 the welcome screen advertises.
The verification step is explicit in VBet’s terms – the customer must be verified – which is consistent with the Commission’s rule that licensed operators verify before the first deposit. Verification is fast for a bettor with a UK passport and a UK bank account, slower for one without. The token is non-stake-returned, and the standard minimum-odds rules on the free bet’s wager apply, though the firm has not been observed to publish them at the welcome-screen level.
The verdict is that VBet is the closest text-book money-back offer on the covered set and the one that wins on alignment between label and structure. The size is modest – £10 nominal against many operators’ £20-£40 of face-value free bets – but the simplicity is the point. A casual bettor who wants a one-and-done welcome with no turnover gymnastics will see this clearly; a high-volume bettor who wants nominal volume will find it small.
Kwiff
Kwiff operates under Commission account 44448 as Eaton Gate Gaming Limited for remote general betting. The firm’s signature feature is Supercharge, an instant odds boost on a bet – the published example is a 2/1 (3.00) selection boosted to 20/1 (21.00) – applicable to single or multi bets on any sport.
Supercharge is the closest Kwiff product to a money-back offer, although it is structured as a price boost rather than a refund-on-loss. The boost multiplies the odds paid on a winning bet rather than crediting a free bet on a losing bet, and the pricing reflects the rarity – a 20/1 (21.00) win on a 2/1 (3.00) selection is a significantly larger return than the original bet would have produced. Kwiff’s welcome is structured around this mechanic rather than a money-back refund, and the experience of using it is closer to a casino-style surprise than a transparent customer-protection feature.
The verdict is that Kwiff is the brand for the bettor who values a price boost at the bettor’s expense rather than a refund at the operator’s. A serious single-line bettor will find the feature useful; a bettor who prizes predictable settlement will find the structural surprise unattractive. The firm is a credible licensed bookmaker with a distinctive product, and the question for any customer is whether the Supercharge mechanic is welcome or merely colourful.
10bet
10bet operates under Commission account 43173 as Blue Star Planet Limited for remote general betting. The advertised welcome is a 100% up to £50 betting bonus for UK sign-ups, with daily free bets and free spins. The free-spins component is the key phrase in this offer; under the January 2026 promotion rules, a mixed-product promotion that pairs a sports-bet requirement with a casino-style free-spin element is not permitted at a licensed operator. Whether 10bet’s app-store description reflects the current live product is not established; what is established is that no such mixed-product welcome is lawful at a Commission-licensed brand from 19 January 2026.
A 100% up to £50 betting bonus is a deposit match; the term “deposit match” describes a bonus structure in which the operator credits a bonus proportional to the customer’s first deposit, normally subject to a stated maximum and a wagering requirement. The £50 maximum caps the bonus at a small absolute value; the qualifying multiple determines how much turnover is required. The 10x cap from the Commission rule book means the worst-case turnover at £50 is £500, which the bettor must clear in qualifying bets at the minimum odds and within the window specified in the terms.
The verdict is that 10bet offers a deposit-match welcome whose face value sits below the £40 free-bet clusters several competitors run. The mixed-product angle in the app store description raises a flag that requires the bettor to check the current live terms carefully, because no mixed-product welcome is lawful under the post-January 2026 promotion rules. A bettor who reads the live welcome page rather than the app-store summary will see the live offer, which may be a betting-only structure.
Star Sports
Star Sports operates under Commission account 9177 as Star Racing Limited for remote general betting. The product is pre-event and in-play with Bet Boosts, Daily Specials and Weekend Enhanced Boosts, plus in-play betting on football, horse racing, golf and US sports. Star Sports is an independent British bookmaker with a long high-street history, and the welcome mechanics reflect that lineage rather than a contemporary app-store acquisition funnel.
A welcome offer that consists primarily of enhanced odds and price boosts is the standard Star Sports pattern. The “money-back” label is not typically used in Star Sports’ published welcome – the firm’s signature is the boosted price and the daily specials – and a bettor who wants a money-back structure specifically will find Star Sports a poor fit. The licence is among the older ones on the register, which is worth knowing for a bettor who values regulatory standing over novelty.
The verdict is that Star Sports is the operator for the racing and football bettor who values the boosted-price stack over the welcome refund. The brand is honest about what it sells and disciplined in what it offers; a reader looking for a ‘money-back as free bet’ promotion will not find one here, as the firm pursues a different strategic focus.
Sporting Index
Sporting Index operates under Commission account 27343 as Sporting Index Limited for remote general betting. The new-customer offer is a £10 fixed-odds bet at minimum odds of 1/2 (1.50) unlocking 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 structure is unusual on the covered set – it mixes fixed-odds and spread-bet products, which is a feature rather than a bug at a firm whose core line is spread betting.
The financial-spread-betting side of Sporting Index sits under a separate regime – financial-spread products are regulated by the Financial Conduct Authority rather than the Commission – and the fixed-odds side is regulated by the Gambling Commission. The non-in-play, non-cash-out condition on the qualifying bet is unusual: it rules out the in-play price-movement trade and the early-cash-out transaction, which means a sophisticated user cannot grind the qualifier for profit.
The verdict is that Sporting Index is for the bettor who wants a mixed fixed-odds and spread-betting starter. A spread-betting customer will see the welcome as a packaged introduction to the firm’s two formats; a fixed-odds-only customer will find the headline confusing and the spread-bet credits of marginal value. This offer functions as a hybrid welcome rather than a straightforward refund mechanic.
Fafabet
Fafabet operates under Commission account 57385 as Taichi Tech Limited for remote general betting. The product includes Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days – if the starting price (SP) is bigger than the original price, the bigger odds are paid. BOG (Best Odds Guaranteed) is a price-shift protection rather than a money-back refund.
The mechanism is different from a money-back deal. The customer takes the early price; if the SP drifts out, the customer is paid at SP rather than the price taken – effectively refunding the difference between the two. BOG does not require a losing bet, does not produce a free bet, and does not pay cash back. Its cost to the bookmaker is the difference between the early price and SP, which is a measurable and predictable line item for a firm active on racing.
The verdict is that Fafabet is the racing-first operator in this set, and its refund is a price-protection rather than a stake-protection. A racing bettor who consistently takes early prices will see value from BOG; a casual bettor who rarely bets racing will not engage with the product. There is no money-back-as-free-bet welcome here; the brand’s signature is elsewhere.
How the welcome offers compare
The table below sets the four publicly verifiable columns side-by-side: the licence holder as the Commission’s register publishes it, the account number a bettor searches the register against, and what the operator’s own terms state on the qualifying bet, refund form, and any minimum price or expiry research documents. Two columns of the spec – minimum price on the qualifier and the credit form – vary by operator and are listed; the rest of the terms worth comparing are noted in the per-operator write-up above rather than duplicated in a column.
| Brand | Licence holder (Commission account) | Qualifying bet and minimum price | Refund form and credit / expiry |
|---|---|---|---|
| Smarkets / SBK | Smarkets (Malta) Limited (39173) | £20 first deposit; £20 bet at minimum odds 3.0 | £60 in free bets within 48 hours |
| William Hill | WHG (International) Limited (39225) | Acca of 2+ legs at 1/5 (1.20) per leg | Acca Boost 3% (double) to 200% (20+ legs); cap £10,000 online; runs to 30 May 2027 |
| Bet600 | Tyche Tech Limited (44731) | 5 qualifying single bets of £10+ at Evens (2.0)+ within 7 days | 1 × £10 free bet at the end |
| Coral | LC International Limited (54743) | £20 bet at minimum odds 2.0 (1/1) within 7 days | £40 in free bets within 7 days, 7-day expiry |
| VBet | SCGO Limited (44662) | First-ever bet of £10+ that loses | £10 free bet on settlement |
| Kwiff | Eaton Gate Gaming Limited (44448) | Supercharge applies to single or multi bets on any sport | Price boost at settlement (not a refund) |
| 10bet | Blue Star Planet Limited (43173) | 100% deposit match, up to £50 | Bonus credited, 10x turnover cap |
| Star Sports | Star Racing Limited (9177) | Welcome boosted-odds products; no money-back label | Per-brand promotions |
| Sporting Index | Sporting Index Limited (27343) | £10 fixed-odds bet at 1/2 (1.50); no in-play, no early cash-out | 3 × £10 fixed-odds free bets, plus spread-bet credits |
| Fafabet | Taichi Tech Limited (57385) | Best Odds Guaranteed from 9am on UK and Irish racing | SP override (not a refund-on-loss) |
The columns show three patterns. First, the qualifying thresholds on welcome offers cluster between 1.50 and 2.00 for most operators, with Smarkets/SBK the notable exception at 3.0. Second, the refund forms are uniformly non-stake-returned free bet tokens; only Coral offers a face-value ratio that exceeds the £20 qualifier in a memorable way. Third, the welcome products that are not money-backs at all – William Hill’s acca boost, Kwiff’s Supercharge, Star Sports’ specials, Fafabet’s BOG, Sporting Index’s hybrid welcome – reflect each brand’s core product line rather than the marketing label the welcome screen uses. The “money-back” promise on this shelf is a brand-language signal rather than a single, comparable product.
The free-bet calculation, stated plainly
A free bet worth £10 nominal, placed on a market priced at decimal odds of 1.90 (9/10 in fractions) on each side of a two-way outcome, and against a 5% market margin, has an expected value of approximately £4.50 over many such bets. Assumptions: only the bonus amount is wagered once, the stake is not returned on a winning free bet, the market on which the free bet is placed is balanced so that the payout share and the margin constant hold, and the bettor cannot choose which side of the market wins.
That number is an estimate, not a guarantee. Placed on a market with a higher margin (an underdog-heavy outright price, a same-game multi with a 7-10% margin), the realised value is lower. Placed on a market with a thinner margin (a top-flight 1X2 with 3% margin), the realised value is closer to £4.70. Placed at a longer price – 2.50 rather than 1.90 – the realised value rises to roughly £5.50 on the same margin. The headline figure of £10 is the marketing number. The realised figure that follows from the calculation lands in the £4.50-£5.50 band on the parameters a typical UK free-bet minimum-odds requirement forces.
The 10x bonus cap affects this calculation only when there is a wagering multiplier attached. A free bet with no clearing requirement – a token to use and withdraw – is settled on the calculation above and is unaffected by the cap. A bonus balance that must be wagered ten times before withdrawal will, on a £10 starting balance and £100 of clearing turnover at the operator’s market margin, return an expected value to the bettor that is lower still – the clearing bets pay back roughly 95% of stake as a payout share, so the net position after clearing is the bonus amount less the operator’s take on the clearing turnover.
How to read the comparison
Three things make the difference on this set. The qualifying odds threshold determines who can clear the welcome – higher minimums screen out casual play and increase the conversion rate from those who do qualify. The face-value ratio of refund to qualifier determines the headline generosity, and is the figure the marketing screen displays most prominently. The expiry and stake-not-returned condition determine how much of that headline figure a casual bettor will actually realise – tighter expiries forfeit more free bets to the operator, and a stake-not-returned rule is universal on the set and accounts for the £4.50-on-£10 figure calculated above.
The calculation is a statistical estimate. It is not what any individual free bet pays out. It averages many bets under the stated assumptions, and an individual bettor can do meaningfully better (using the token on a thin-margin market at long odds) or worse (using the token on a heavy-margin outright at short odds). For the comparison on this page, the £4.50-£5.50 band is the right reference: the operators whose free-bet product falls inside that band on nominal value are not distinguishable on the calculation, and the differentiation lives in the threshold, the expiry, and the brand’s broader product.
The two operators whose welcome is not a free bet at all – William Hill (acca boost), Kwiff (Supercharge), Star Sports (specials), Fafabet (BOG), Sporting Index (hybrid) – are scored on a different scale. They are not weaker or stronger on this comparison; they simply answer a different question. The bettor whose weekly stake is on accumulators will find William Hill rewarding; the bettor whose stake is on racing singles will find Fafabet rewarding; the bettor who wants the textbook money-back-as-free-bet on a first bet will find VBet the closest match in terms of marketing label.
Frequently asked questions
What is a money back as free bet deal?
A money back as free bet deal refunds a losing qualifying bet as a free bet token rather than as cash. The token can be wagered once, the stake is not returned with the winnings, and a minimum odds requirement and an expiry window almost always apply. The customer does not recover the full stake as spendable money.
What does money back in free bets mean?
It describes the form of the refund: the bookmaker credits free bets into the customer’s account in place of the original stake. The marketing phrase “money back” refers to the notional refund; the realised wallet position is the free bet tokens, not the original cash. The face value of the tokens is the marketing number; the realised value is smaller once the stake-not-returned rule is applied.
What does “use money back in free bets” mean operationally?
It means the customer is expected to place the credited tokens on a new qualifying wager before they expire. The token is a wagering instrument, not a withdrawable balance, and the customer’s next steps are to back a market meeting the minimum-odds rule and to settle the wager within the expiry window. Withdrawable balance only follows when the subsequent wager wins and, where the operator applies one, the wagering multiplier has been cleared.
What is the maximum wagering requirement on a betting bonus in Great Britain?
The Commission’s promotion rules, in force since 19 January 2026, cap the wagering requirement on a betting bonus at 10x. The cap applies where a wagering multiplier is attached at all; whether it applies to free bets with no attached wagering condition is not established in the public materials. Mixed-product promotions are banned under the same rule set.
What do minimum odds and the wagering requirement mean in a sign-up offer?
Minimum odds are the threshold below which a bet does not qualify for the offer – typically 1.50 (1/2) to 2.00 (1/1), and unusually 3.0 in the SBK case. The wagering requirement is the multiplier the customer must bet through before any bonus balance becomes withdrawable, capped at 10x under the post-January 2026 rules. Together they set the entrance condition (qualifying bet) and the exit condition (turnover) of a welcome offer.
Why is the stake of a free bet not paid back with the winnings?
Free bets are structured by the operator as stake-not-returned tokens, which is what sets them apart from cash refunds and from each-way bets where the stake is returned on the win part. The condition is universal among the operators covered here; it is what makes the realised value of a £10 free bet roughly £4.50 in expected terms on a 5% margin market, rather than the £10 the headline states. The rule is a feature of the product, not a defect.
