Written as of 27 October 2026 and checked against the public register held by the Gambling Commission (account numbers and licence holders as quoted by each operator’s own UK site).

A free bet looks like a gift: a token worth £10, £30, sometimes £60, sitting on a new account with one condition attached — “bet at minimum odds”. The token is the easy part. The hard part is everything wrapped around it, and that wrapping is where the value lives or drains. In Great Britain, the Gambling Commission has spent the last two years tightening that wrapping: a 10x cap on bonus wagering, a ban on mixed-product deals, a £150 financial vulnerability check that fires before a customer’s bankroll ever builds. The token still exists. What it is worth has changed.

This page reads those welcome offers as offers, not as adverts — what each one is, how it pays out, what condition it carries, and which reader it suits. It covers the payments and speeds behind a first deposit, the predictions markets where a free bet is most often spent, the sports and tournaments those tokens land on, and a ranked comparison of ten GB-licensed bookmakers. The legal frame sits where a UK bettor needs it — what a GB licence actually guarantees — and a responsible-gambling section names the tools that exist behind the offer before a reader has to ask.

The angle is cost. A £30 free bet that expires in seven days, demands a minimum price of 1/2 and returns its profit without its stake is not the same deal as a £40 free bet across four tokens usable only on football accumulators. The arithmetic differs by enough that two readers should sit down with two different brands. Calculating the average value of one of those tokens at an illustrative two-way market of 1.90 / 1.90 — the kind of tight line a £10 token often lands on — comes out to a fraction of the face value, and that fraction is what defines whether the welcome matters.

How free bets actually pay out

A free bet is a token credited to a new account. The bettor’s own cash pays the stake; the bookmaker pays the profit when the bet wins. The stake does not come back.

That sentence is the single most important one on this page, because it inverts what the marketing picture suggests. A £10 free bet at odds of 5/1 (decimal 6.00) does not return £60. It returns £50 — five times the stake, paid as profit, with the £10 stake gone. A £10 free bet at evens (decimal 2.00) returns £10, again as profit, again with no stake recovered. The headline number on the welcome page is face value; the realised value is wherever the bet lands, priced by the bookmaker.

A useful way to keep this straight: the average value of a free bet whose stake is not returned is the stake, multiplied by a quantity that depends on the odds you take and the margin of the market you take it on. At a balanced two-way line priced at 1.90 / 1.90, the bookmaker’s overround on the market is roughly 5.3 percent (the payout share is 1 / (1/1.90 + 1/1.90), or about 94.7 percent). A £10 free bet at those odds averages around £4.74. That is the realised worth of the token before any minimum-odds condition or expiry deadline narrows it.

A free bet whose stake does come back sits in a different category — most often called a “bet credit” or “non-stake-returned” bonus. Several GB brands name their tokens as one or the other in their own terms; the rest let the small print do the work. The difference to a bettor is the difference between £10 + profit and profit alone, and any comparison that elides it understates the cheaper offer.

Expiry matters as much as the maths. Sky Bet’s free bets expire 30 days after credit; Coral’s expire seven days after issue; Unibet’s expire within seven days of credit. A token that arrives during a busy sporting week — Cheltenham, the Grand National, Premier League run-in — has somewhere to land. One arriving during a sparse fixture list is wasted by the clock before the bettor finds a price they like.

What the betting bonus looks like after the wagering requirement

A welcome bonus is a different product from a free bet. The bookmaker credits cash to the account on top of the deposit — a £20 deposit, a £20 bonus — and the customer wagers the combined balance a number of times before withdrawing any of it. Wagering factor is the multiple: 1x, 3x, 5x, sometimes higher. The Commission’s rule since 19 January 2026 caps that factor at 10x. Anything above that on a UK-licensed site is a violation that the operator corrects on the register, not a quirk of its terms.

A 10x cap changes the shape of the deal. Before the cap, a £10 bonus at a 50x factor meant £500 of qualifying bets before withdrawal. After the cap, the same £10 bonus needs £100 of qualifying bets. The headline number has not changed; the cost of clearing it has halved. Operators responded by trimming bonus amounts and tightening the markets on which the bonus can be cleared. The 10x number is the most important regulatory change in this space since the credit-card ban in 2020.

A separate rule, also in force since January, bans mixed-product promotions: an offer that conditions a bonus on gambling across two or more product types (betting and casino, betting and bingo, betting and lottery) is not allowed on a GB-licensed site. A bettor who wants both a sportsbook welcome and a casino welcome on the same operator has to claim them on their own terms. The rule’s intent is to stop a casino bonus being used to drag a bettor through a sportsbook bonus and vice versa; its effect is that joined-up cross-product welcome packages have largely disappeared.

Minimum odds, qualifying bets and the small print

Almost every welcome offer comes with a minimum odds qualifier on the first bet. Coral and Unibet set the bar at 2.0 (1/1); Spreadex sets it at 1/2; Sky Bet asks for 5p at 1/1 or greater on the qualifying bet. The price floor exists so that a bettor cannot clear the bonus on a nailed-on favourite, and the qualifying bet is the price of admission. A first deposit at Sky Bet of £5 and a first single bet of 5p at 1/1 is enough to trigger the £30 in free bets on a £30 face split across three tokens.

The wagering requirement on any free bet won, where one applies, runs similarly. Betway’s free bets carry a 1x factor at odds of 1.75 or higher — a single turn of the bonus at a minimum price before withdrawal. Most other brands in the comparison set carry no wagering requirement on the free bet itself, only on bonus cash. The phrasing varies; the substance does not. Where a 1x turnover is set, the bettor has exactly one chance to convert the bonus to cash: at the qualifying price, on the qualifying markets, before the deadline runs out.

Payments and payout speed at the cash desk

A welcome offer is claimed at the cashier. The first deposit usually has to be a debit card or an instant bank transfer, with Apple Pay, Google Pay, PayPal and a handful of e-wallets locked out of the qualifying deposit at some brands and accepted at others. Coral’s welcome offer, for example, is qualified only by a debit card or instant bank transfer, even though its payment page runs wider — Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly sit on the cashier. LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay at the deposit step.

The reason for that gate is anti-money-laundering and bonus-abuse regulation. The Commission’s identity-verification rule, in force since 7 May 2019, requires name, address and date of birth confirmation before a customer can deposit or gamble — including with a free bet or bonus. A payment method tied to a verified identity, of which a debit card is the cleanest example, is easier to police than an e-wallet that sits one step removed from a bank. The customer does not see the rules behind the gate. They see a deposit method that works and a deposit method that does not.

Withdrawal speed is the metric that matters most to the bettor after the welcome bonus is cleared. The fastest routes run through the same instant rails that the deposit took — Visa Fast Funds, instant bank transfer via Trustly or TrueLayer, PayPal in some shops — and pay out inside two hours. A standard bank transfer sits at one to three working days. E-wallets vary by provider. The £150 financial vulnerability check, fired in a rolling 30-day window since 28 February 2025, adds a step that did not exist 18 months ago: a public-records check for bankruptcy or county court judgments before any withdrawal can move. It is not an income check; it is a marker for financial distress, and a flagged record routes the customer to safer-gambling tools rather than blocking withdrawal outright.

A separate piece of regulation governs deposits over time. Operators must offer a gross deposit limit on a fixed time frame. The first phase of those rules landed on 31 October 2025. A second phase, originally planned, was postponed to 30 September 2026; whether that phase is in force on the day a reader visits is a moving fact the operator’s own cashier will confirm. There is no state-set ceiling on deposits, and limits are the customer’s own choice — the rule is that the choice has to exist on a fixed timeframe the operator cannot shrink.

Predictions, fixtures and where a free bet actually lands

A free bet is worthless until it is spent. A first-week welcome during the Cheltenham Festival, the Grand National meeting, the Premier League run-in or the start of the football season has the pick of the cards. A welcome during a quiet July week has fewer. The bookmaker does not time welcome offers around the calendar; the bettor’s job is to claim at a moment when the sporting calendar will carry the token.

Predicting football is the dominant use. Same-game multiples, often called bet builders, let a bettor combine two or three outcomes from a single match into one bet — both teams to score, over 2.5 goals, a first goalscorer. The free bet token is usually restricted to single bets or each-way bets on horse racing, sometimes to multiples of a defined size. Sky Bet’s free bets can be used only on single or each-way markets, not multiples, and exclude virtuals. BoyleSports Acca Loyalty requires opt-in, a £5 minimum stake and five or more settled legs to qualify for the free-bet refund leg. The token is shaped to send the customer onto the bookmaker’s own markets rather than to allow a free ride through someone else’s line.

Best odds guaranteed runs on British and Irish horse racing. A bet on a horse at a shorter price than its starting price pays out at SP if SP is bigger; the difference arrives as extra return with no extra stake. Best odds guaranteed does not apply to free bets at every operator. Where it does, a horse backed at 6/1 that returns at 8/1 SP earns the bigger price on the free-bet token. Where it does not, the token takes the lower of the two.

In-play betting is the second market where a free bet is often spent, and it is the market where the rules are most often re-read at speed. Betfair offers an in-play sportsbook with Bet Builder, free live streaming of UK and Irish racing and a 90 Minute Payout market that settles bets on stoppage-time goals. Kwiff’s Supercharge feature can randomly boost the odds on a bet from 2/1 to 20/1; on a single or multi bet on any sport, the value swings wildly from one customer to the next. LiveScore Bet’s sportsbook carries the same in-play, acca-style features as the bigger names. Unibet’s site carries Uniboosts, in-play, Bet Builder, live streaming through Unibet TV, Cash Out on thousands of markets and best odds guaranteed on horse racing across the same product surface.

The third market is American. NBA, NFL, NHL and UFC all run heavily through the GB-licensed sportsbooks, with each operator carrying its own set of futures, player props and live markets. Star Sports publishes pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts, plus in-play betting on football, horse racing, golf and US sports. The welcome offer is sport-agnostic; the bettor’s own interests set the destination.

Ranking ten new customer free bets

The ten operators ranked below all hold a Gambling Commission remote licence for Great Britain and run a UK-facing sportsbook. Each is described in terms the operator’s own terms and the Commission’s public register support. Where a brand’s profile does not match the subject — a free-bet guide and a brand whose welcome is essentially bet-builder-driven — the gap is named in one sentence and the rest of the profile is left intact. None of these are recommendations. They are the GB-licensed operators that the comparison turns up, and the verdict at the bottom of each is the page’s own read of what is there.

Each operator below is described with the page’s own verdict on the welcome, alongside the regulatory and product details that decide who the offer suits.

Sky Bet

The headline offer — £30 in free bets split across three £10 tokens — is the cleanest in the comparison set. A £5 minimum deposit and a 5p qualifying bet at 1/1 are the lowest admission thresholds any major GB sportsbook asks for; the £30 is a healthy face value for the money in. The catch is the usage rules: single or each-way markets only, no multiples, no virtuals, 30-day expiry, stake not returned. Sky Bet’s product line — strong on horse racing with best odds guaranteed, plus football, NFL and a broad in-play book — gives the tokens somewhere to land within those constraints. The user worth pointing at Sky Bet is one who wants to back a couple of fancied horses or a Saturday football single and is happy trading multi-leg accas for the clean welcome math.

Betfair

Betfair sits on two products in one wallet: an exchange and a sportsbook. The sportsbook’s free-bet welcome is one route in; the exchange’s commission structure (charged on net winnings only) is another. The risk on the exchange is that a free bet from the sportsbook wallet does not map cleanly onto an exchange price, and a bettor looking for an “edge” through lay betting has to learn that segment rather than rely on the welcome alone. The sportsbook, by contrast, is unremarkable: in-play, Bet Builder, free live streaming on UK and Irish racing and football, 90 Minute Payout on stoppage-time goals. Betfair suits a reader who already understands the exchange model and sees the welcome as a top-up rather than the centrepiece.

Coral

Coral’s £40 in free bets for a £20 qualifying bet is the most generous headline in the comparison, and it runs on top of a parent (LC International Limited) that also runs Ladbrokes. The term that cuts the headline is the qualifying payment: a debit card or instant bank transfer, not Apple Pay or an e-wallet, even though the cashier is wider. £40 in free bets issued within seven days, expiring seven days after issue, with no wagering requirement on the bonus itself. Coral carries the daily Reward Shaker, an Odds Booster on hundreds of markets and Football Super Series with a £10,000 jackpot, so the welcome lands in a product surface that does not stop working once the tokens do.

Paddy Power

Paddy Power and Betfair share a parent, but Paddy Power’s product direction is its own — price boosts, money-back specials on named events and a louder brand voice. The sportsbook’s welcome offer mirrors the Betfair sportsbook in shape; the difference is the promotional calendar layered on top. The user who wants novelty-market markets (politics, TV specials) and who treats the welcome as one of several promotional rails rather than the centrepiece will find Paddy Power useful. The user who just wants a clean welcome for cash bets will not find it different enough to switch.

William Hill

William Hill’s headline football product is the Acca Boost, which covers accumulators of two or more legs at minimum odds of 1/5 per leg, from 3% on a double to 200% on twenty legs and capped at £10,000 per online bet. The promotion runs until 30 May 2027. The welcome offer is its own product; the Acca Boost is what the customer meets once the welcome has cleared. The reader who bets football multiples and wants the boost pays off for in steady volume; the reader who backs singles at short prices will not see it fire.

Betway

Betway’s minimum deposit is £10, and its free bets carry 1x wagering at minimum odds of 1.75. A 1x turnover on a free bet is light by GB standards, and 1.75 (decimal) is a reasonable floor. The product covers football, horse racing, e-sports and a deep in-play menu. The brand carries the Betway Vegas and Betway Slots side, which is also where the mixed-product ban has bitten: a sports welcome and a casino welcome are two separate tokens, not one bundled deal. The user worth pointing at Betway is one who plays both products and is happy to claim two welcome offers in sequence.

Unibet

Unibet’s welcome — £40 in free bets for a £20 qualifying bet at 2.0 (1/1), expiring within seven days — sits alongside one of the deeper product surfaces in the comparison. Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play, Cash Out on thousands of markets and Best Odds Guaranteed on horse racing are all live on the UK site. The expiry is tight: seven days from issue is not enough for a bettor to wait for the right fixture. Platinum Gaming Limited holds the GB licence (account 45322) on Unibet’s UK site, and the brand states it has operated since 1999.

Ladbrokes

Ladbrokes and Coral sit under LC International Limited, and the comparison reads them as siblings with different brand voices. Ladbrokes’ welcome is comparable in shape; the brand’s horse-racing heritage shows through in markets, BOG coverage and the depth of the ante-post book. Acca Insurance on football accas is a long-running Ladbrokes product. A reader who prefers a quieter brand voice and a deeper horse-racing product will find Ladbrokes easier than Coral; the welcome math is the same.

Bet365

Bet365 does not run the largest headline free-bet welcome, and it does not need to. The product surface — Bet Builder+ combining markets from one event pre-match and in-play, Super Boosts, Winnings Boosts on Bet Builders and selected singles, daily Bet Boosts — is what the customer meets on day two. Hillside (UK Gaming) Limited holds the GB licence (account 42629). The user who ends up at Bet365 usually does so for a market the smaller books do not carry, not for the welcome alone.

Midnite

Midnite is the newest GB-licensed sportsbook in the comparison. The site shows in-play, an acca builder, popular accas and price boosts with maximum-stake limits. The welcome’s exact terms live in the app, and the value is a moving fact the operator updates more often than the bigger brands do. A reader looking for a fresh product surface with cleaner pricing on acca markets is the likely user; a reader looking for the same offer as the legacy brands will find fewer references and will need to read the in-app terms.

What Great Britain law gives a free-bet customer

The Gambling Commission is the regulator for the whole UK commercial market. It licenses under the Gambling Act 2005, which covers England, Scotland and Wales; Northern Ireland has its own older statute and is outside this Act, so a “GB-licensed” operator is licensed for Great Britain but not for Northern Ireland. Since the Gambling (Licensing and Advertising) Act 2014, an operator needs a Commission licence wherever it is based, if its remote facilities are used in Great Britain — a Curaçao, Maltese or Gibraltar licence is not a substitute for the section 33 / section 36 requirement. There is no state monopoly, and the Commission can license any number of operators that meet its conditions.

Five licence categories sit on a sportsbook: remote general betting standard (real events), the standard category for football, horse racing, tennis and the rest of the actual sporting calendar; remote general betting standard (virtual events), a separate category; remote general betting limited; remote pool betting; and remote betting intermediary, which covers betting exchanges. An operator may hold one or several; the categories show on the register against each account. Geoff Banks, Midnite and Sky Bet each hold the standard real-events licence among others; Sporting Index runs both standard fixed-odds and spread betting under one account set.

The checks the Commission enforces are not abstract. Identity verification runs before the first deposit and before any gambling — name, address, date of birth — and the rule has been in force since 7 May 2019. A free bet sits inside that verification. The £150 financial vulnerability check (LCCP 3.4.4, in force since 30 August 2024 with the £150 threshold since 28 February 2025) fires in a rolling 30-day window on deposits minus withdrawals: a public-records check (bankruptcy, county court judgments) that is not an income check and not a credit-reference check. A flagged record does not block withdrawal; it routes the customer to safer-gambling tools.

No list of permitted bets exists in statute. An operator offers markets under its own rules and the Commission’s Licence Conditions and Codes of Practice (LCCP). In-play, e-sports, novelty markets and pool betting are all governed by those licence conditions rather than by a separate statute. The Commission’s enforcement against an operator is the lever; the statutory position is permissive and the regulation is by conditions.

A separate regime covers financial spread betting, regulated by the Financial Conduct Authority rather than the Commission. Spreadex is regulated by both bodies, depending on the product — fixed-odds betting under the Commission, spread betting under the FCA — and the operator states that spread betting losses can exceed the deposit. That statement is the official warning on the product: it is a leveraged bet, and the customer needs to understand that before a free-bet welcome leads them onto a spread-betting product page.

The credit-card ban and the identity verification that catch every customer

No credit cards at gambling. Since 14 April 2020, the Commission has banned credit cards for any gambling transaction in Great Britain, including credit-card-funded payments through an e-wallet. Debit cards are not covered by the rule. The ban catches the slip between buying time on a card and betting on a Tuesday night, and it does not catch the direct debit. A reader who only carries a credit card cannot fund a betting account.

Identity verification is the second universal rule. Before the first deposit, name, address and date of birth are checked — including with a free bet or bonus. The check is automatic on the major operators; on the smaller ones, it can take 24 hours or more. A reader whose first action after registering is to claim a welcome offer will see the cashier pause while the verification runs, and the pause is the regulation, not a quirk.

Advertising: who may appear, not who may bet

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 LCCP marketing conditions. CAP Code section 16: marketing must be socially responsible, must not be strong in appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling or play a significant role (with an exception for advertising placed where a bet can be made directly). The rule is about who appears in the ad, not who may register. A reader who is 18 or older is free to register; the ad is restricted, the customer is not.

The promotion rules effective 19 January 2026 sit on top of those advertising rules. Wagering requirements on bonuses are capped at 10x, and mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery — are banned on GB-licensed sites. Whether the cap applies to free bets where there is no wagering condition is not established. Two operators offering what looks like the same headline can sit on different sides of the cap once the small print is read.

“Whistle-to-whistle” is an industry code, not law. Since 1 August 2019, betting advertisements are not shown on television in the five minutes before a live sporting event to the five minutes after it, before the 9pm watershed — horse and greyhound racing except. The Premier League clubs’ voluntary withdrawal of gambling sponsorship from the front of matchday shirts, from the 2026/27 season, is not law. Sponsorship from bookmakers on shirt sleeves and around the pitch is not affected.

Offshore: what an unlicensed site costs

A GB licence is compulsory at the point of consumption. Section 33 of the Gambling Act 2005 makes providing gambling facilities in Great Britain without the licence the Act requires an offence; it is aimed at the operator (a summary conviction can produce up to 51 weeks’ imprisonment or a fine up to level 5). No offence aimed at a customer who merely bets on an unlicensed site has been found; the cost of using one is protection-based, not criminal. A reader on an unlicensed site has no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check. The funds on the unlicensed site can still go missing — and there is no British body to pursue them.

Enforcement is disruption, not blocking. The Commission uses cease-and-desist notices, referrals to search engines and work with registrars, hosts and payment providers. Court-order DNS blocking powers have been given, or are about to be given, to the Commission; ISP blocking is not in operation as a default. Honest framing: licensed means checks, limits, GAMSTOP and the bonus cap, and identity verification before the first bet; unlicensed means none of those protections, with the risk of funds withheld when no British body can compel their return. Neither is “the safe choice” by default.

Tax on winnings: the player pays nothing

The player pays no tax on betting winnings in Great Britain, as a matter of general information rather than tax advice. A professional gambler should ask HMRC or an adviser; the casual bettor does not. General Betting Duty is the operator’s tax on gross profits, currently 15 percent; from 1 April 2027 a new remote betting rate of 25 percent 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 percent. Until 1 April 2027 the remote rate stays at 15 percent. Whether operators pass duty on through odds is not established. Spread betting has its own rates — 3 percent financial, 10 percent other.

The Commission’s statutory levy is a separate charge, not a tax. The two often get conflated in marketing copy; the bettor pays neither.

Responsible gambling: the tools that exist behind the offer

The tools listed below are not extras. They are licence conditions on a GB-licensed operator and obligations under the LCCP. A bookmaker without them is not GB-licensed. A bookmaker with them but with a thin safer-gambling page is one to read carefully.

GAMSTOP is the multi-operator self-exclusion scheme, mandatory for online operators since 31 March 2020. A self-exclusion runs six months, one year, five years or five years with auto-renewal. After the minimum period, an exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps; betting shops sit on a separate service. A reader who wants a single one-stop exclusion from every UK online bookmaker uses GAMSTOP; it cannot be undone early, and the seven-year tail is part of its structure.

Deposit limits are a separate tool. Operators must offer a gross deposit limit on a fixed time frame. The first phase of the deposit-limit rules landed on 31 October 2025; the second phase was postponed to 30 September 2026, and whether it is in force on the day a reader visits is a moving fact the cashier will confirm. There is no state-set ceiling, and a limit set to zero is the customer’s own decision.

Time-out and product-block tools are also licence-conditioned. A 24-hour cool-off, a one-week suspension and longer exclusions all sit on a responsible-gambling page. Some operators — DAZN Bet is one — offer deposit limits, loss limits and wagering limits as standard safer-gambling tools. Others offer the framework but bury the controls; the regulator is the auditor, the customer is the one who reads the page.

Help lines and clinical services sit outside the bookmaker. GamCare runs the National Gambling Helpline. GambleAware signposts NHS gambling clinics. Gamblers Anonymous offers peer support. None of these is connected to a free bet, and none of them depends on the customer having opened an account.

A separate note on the named-account and source-of-funds rules. The Commission’s anti-money-laundering framework requires source-of-funds questions at higher spend — what a customer’s source of wealth is, what their occupation is, where the deposit came from. A reader who plans to deposit a meaningful sum will answer those questions; a reader whose first deposit is £20 will not. The questions run in proportion to the deposit and the play.

What a free bet is actually worth, by the arithmetic

A free bet whose stake is not returned is worth, on average, the stake multiplied by a quantity that depends on the price the bettor takes and the margin of the market. At a balanced two-way line at odds of 1.90 / 1.90, the bookmaker’s margin over the market is roughly 5.3 percent: the payout share is the sum of the implied probabilities (1 / 1.90 + 1 / 1.90, or about 1.053), so the margin is the rest, around 5.3 percent. A £10 free bet at those odds averages £10 × (1.90 − 1) / 1.90 × 0.947, or about £4.49 — depending on the rounding assumption used in the second step. A £30 free bet of the same shape averages around £13.50; a £40 free bet, around £18. The numbers shrink with the margin. A bookmaker running a 7 percent margin on the same line drops the realised value to about £4.40 on a £10 free bet; on a 4 percent margin, it lifts to around £4.55. The realised value of a “£30 free bet” sits between roughly £13 and £14 against any reasonable margin in this market.

That is the headline number a bettor should hold in their head when they weigh one welcome against another. A £40 free bet at 7 days’ expiry, restricted to football accumulators, will not deliver £40; the headline is worth roughly £18 against the arithmetic. A £30 free bet at 30 days’ expiry, usable on singles and each-way horses, will deliver around £14 by the same estimate. Coral’s headline is bigger, but the tightness of the offer — seven-day expiry, football accumulator restriction in part — eats into the realised value faster. Sky Bet’s headline is smaller; the longer expiry and the broader market access let the bettor take the token closer to its arithmetic ceiling.

The condition — that the figure is the AVERAGE over many such bets and many such markets — sits next to the result. A single bet at 1.90 returns either the full profit or nothing on the stake. The bettor’s experience on one welcome offer will vary widely around the average. The arithmetic is what the offer is worth as a class of bet, which is what the comparison is comparing.

The free-bet stake that does come back — the “bet credit” model that some operators use — sits higher in the realised value. A £10 bet credit at 1.90 returns £19 if the bet wins: £9 profit and the £10 stake. The average value, by the same calculation but with the stake included, runs roughly 50 percent higher than a free bet whose stake is not returned. A bettor who can choose between the two should always pick the bet credit on the same fixture, even at a smaller face value, all else equal.

Free bets, broken down by topic

What minimum odds mean in a sign-up offer

Minimum odds are a floor on the price the qualifying bet must take for the welcome to count. The floor protects the bookmaker from a clever customer clearing the bonus on a nailed-on favourite at 1/1000 and then withdrawing. Most GB welcome offers sit at minimum odds of 2.0 (1/1) — a market where the price is roughly even-money. Spreadex’s offer sets the floor at 1/2, where the favourite is shorter than evens; Betway’s post-welcome free bets carry a floor of 1.75 (decimal) on the wagering step; Sky Bet’s qualifying bet is a near-trivial 5p at 1/1.

A floor at 2.0 means the qualifying bet carries real risk. A £20 bet at 2.0 returns £40 if it wins, of which £20 is profit and £20 is the stake; on a loss, the £20 stake is gone. A customer who clears a Coral welcome with a £20 qualifying bet at 2.0 has taken on a roughly 50/50 outcome for £20 of their own cash before the £40 in free bets has been issued. The “free” in free bet sits on top of that first £20, not in place of it.

A floor at 1/2 means the qualifier is much cheaper to take on — the bet will win more often than lose, and the risk is mostly cosmetic. Spreadex uses the lower floor because the qualifying stake is also a fixed-odds bet on a sportsbook, and the lower floor keeps the entry-level barrier low. The downstream rules — 28 days to place the qualifying bet, free-bet tokens usable across fixed odds and spread betting — define the offer’s shape.

Why the stake is not paid back

The stake is not paid back because the free bet is a separate product, not a discount on the stake. The bookmaker pays the profit; the customer’s own cash, never credited, would have paid the stake. A £10 free bet at 5/1 returns £50 of profit, with the £10 stake gone. The same bet at real money, £10 of your own cash at 5/1, returns £60 — £10 stake back, £50 profit. The difference is the £10 stake, and that is exactly what the bookmaker is keeping from the deal.

In practice, that £10 stake is the bettor’s cost for using the token. A reader who treats the token like real money will overstate the welcome’s value by exactly 100 percent of the stake. A reader who treats it as profit-only will be honest with the maths.

Welcome offers vs ongoing offers

A welcome offer is one token per account, claimed once at registration. An ongoing offer is a regular promotion — daily Reward Shaker on Coral, Bet Boosts on Star Sports, Uniboosts on Unibet, the Supercharge on Kwiff, Acca Insurance on BoyleSports — that runs from day one and continues as long as the customer bets. The ongoing offer is, for most readers, the more important figure, because the welcome is spent in seven to thirty days, and most of the customer’s life with a bookmaker happens after.

A bettor who picks a brand on the welcome alone is choosing one token; a bettor who picks a brand on the ongoing product is choosing a year. The two may point in different directions. Bet365’s welcome is not the highest in the comparison; its Bet Builder+ product is wider than most rivals’. Coral’s welcome is the highest; its Acca Insurance and Reward Shaker are different products to its sibling Ladbrokes’. The right starting brand is the one the bettor will still be using twelve weeks later.

A useful checklist for a welcome offer

Five points worth reading on every welcome, in order.

The first is the minimum odds on the qualifying bet. A 5p at 1/1 qualifier on Sky Bet is essentially free; a £20 at 2.0 qualifier on Coral is real money on a real bet. The figure to read is the minimum odds and the minimum stake — both.

The second is the deposit method. The Coral and Unibet welcomes both require a debit card or instant bank transfer to qualify, even where the cashier runs wider. The bettor who planned to deposit via Apple Pay has to change plans.

The third is the expiry. Sky Bet’s free bets expire 30 days after crediting. Coral’s expire seven days after issue. BoyleSports’ acca insurance refund expires seven days from credit. The figure to read is the expiry window — both the length and whether it runs from credit or from the qualifying settlement.

The fourth is the wagering requirement. Betway’s free bets carry a 1x factor at 1.75 minimum. Most other GB welcomes do not carry a wagering requirement on the free bet itself, only on bonus cash. The 10x cap does not apply to a no-wagering free bet because there is no wagering factor to cap.

The fifth is the eligible markets. Sky Bet’s free bets are usable only on single or each-way markets, no multiples, no virtuals. BoyleSports’ acca insurance refund is a free bet usable on football accumulators. The figure to read is the market restriction — the token is shaped to send the customer onto specific lines.

Frequently asked questions

What is a free bet?

A free bet is a token credited to a new account, redeemable at the cashier against a real-money bet. The bookmaker pays the profit when the bet wins; the customer’s own cash would have paid the stake, and because that stake never moved, it is not returned. A £10 free bet at odds of 5/1 returns £50 of profit; the £10 stake is gone. Free bets expire on a fixed window after credit — seven days is common, 30 days at Sky Bet — and any unused value is removed when the window closes.

How does a free bet work in practice?

A new customer registers, makes a qualifying deposit (the amount and method vary by operator), and places a first bet at or above the minimum odds. The free bet is credited at that point. The token sits on the betting slip; placing a bet drops the token’s value onto the slip and the customer’s own cash covers any remainder. If the bet wins, profit lands on the cash balance; the token is consumed; the stake is not returned. Several brands restrict the free bet to single or each-way markets, exclude virtuals, or cap eligible markets at football or horse racing.

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

Ten times. Since 19 January 2026, the Gambling Commission has capped wagering requirements on bonuses at 10x for GB-licensed operators. A £10 bonus used to require £500 of qualifying bets at 50x; the same bonus now requires no more than £100 at 10x. The cap applies to bonuses. Whether it applies to free bets with no wagering condition is not established.

What do minimum odds and a wagering requirement actually mean?

Minimum odds are a price floor: the qualifying bet must be placed at odds at or above the floor for the welcome to credit. A 2.0 (1/1) floor means even-money or longer; a 1/2 floor means roughly two-to-one-on or longer. The wagering requirement is the number of times the bonus (or bonus plus deposit, depending on the bookmaker’s terms) must be turned over in qualifying bets before withdrawal. The 10x cap limits that multiple. A 1x factor means the bettor wagers the bonus once, at the floor or higher, before withdrawing.

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

The stake of a free bet is not paid back because the customer’s own cash never paid it. The free bet token pays for itself against the stake; the bookmaker pays only the profit when the bet wins. The structure is what defines a free bet as a free bet — and it is what defines the difference between a free bet and a “bet credit”, which usually does return the stake. A £10 free bet at 5/1 returns £50; the same bet on a £10 bet credit returns £60 (£50 profit + £10 stake).
