A free bet is the most advertised product in British sports betting, and the least understood by the people who claim one. The headline figure on the offer is rarely the figure that lands in the account, because the wagering requirement, the minimum price, the expiry window and the rule that the stake is not paid back all sit between the two. The bookmaker does not hide those terms; it simply puts them somewhere the eye does not look. The page below is the work of looking. It covers what every free bet and sign-up bonus actually pays out, what it costs the punter to clear, the impact of the Commission’s recent promotion rules, and which of the ten licensed operators this side stands up against the rest.

Which sports and tournaments carry free bets today

The bookmakers this guide covers do not hand out free bets on every fixture, and they do not hand them out at the same time. The pattern follows the calendar: a free-bet headline in October looks nothing like the one a horse racing festival attracts, and a Champions League week prices differently from a Premier League weekend.

Horse racing: the festival calendar sets the rhythm

Free bets attach to horse racing more tightly than to any other sport. Cheltenham in March, the Grand National meeting in April, Royal Ascot in June and the Punchestown festival each bring a flurry of sign-up offers, enhanced odds on festival headlines, money-back specials on the big races and acca insurance on the day’s multi-race cards. Most of these are aimed at new customers; the festival pulls the same bookmaker back into the market with a fresh banner on each of its four days. Existing customers see a quieter set: Best Odds Guaranteed on UK and Irish racing, an each-way offer on the feature race, and acca boosts on the day. The Punchestown meeting in late April closes the spring window; Royal Ascot opens the summer one.

Football: where the free-bet volume actually lives

Football carries the larger share of free-bet turnover. The Premier League runs from August to May; the Championship, the FA Cup and the Carabao Cup fill the midweek gaps; the Champions League, the Europa League and the Conference League run in parallel and overlap with the domestic calendar. Free bets in this sport take a different shape from horse racing. The classic sign-up offer is a fixed stake unlocks a fixed free-bet credit — Coral and Unibet both run “bet £20, get £40 in free bets” with a minimum price of 2.0 (1/1) — and once a customer has cleared that, the weekly rhythm is acca insurance, Bet Builder boosts and Super Boosts on a chosen match. World Cup years tilt everything; the 2026 tournament in North America is the working example for this guide, and bookmakers will run free-bet and enhanced-odds promos from the group stage through to the final, mostly on outright winner and on each day’s biggest game.

Other sports and the year-round offer

Tennis runs from January to November with a free-bet pulse on each Grand Slam. Golf is quieter — the four majors and the Ryder Cup are the only peaks, and free bets in the sport are mostly price boosts on outright winner. Boxing and the UFC cluster around the pay-per-view calendar. American sports — NFL, NBA, MLB and NHL — are year-round for bookmakers that take them seriously (bet365, Sky Bet, Betfair, Ladbrokes), and the free-bet offers cluster around the playoff runs. Esports, virtual sports and novelty markets — politics, TV — carry free bets in smaller amounts and less often. The pattern is consistent across the licensed set: the bigger the fixture, the more generous the headline, and the more demanding the small print.

Why the calendar matters for the offer’s value

A free bet on the Grand National and a free bet on a Tuesday-night EFL Championship match carry the same token — “£10 free bet” — and trade at different values, because the markets around them price differently. The headline figure on the offer does not change; the cost of clearing it does. A reader who uses a free bet on a Champions League match at decimal odds of 3.00 collects more than one who uses the same free bet at odds of 1.50, because the higher price multiplies a larger profit onto a stake the bookmaker has not returned. The arithmetic is the same on every sport, and the calendar decides which markets are open with prices worth using.

The ten bookmakers this guide reviews — and how they compare

The ranking below closes Cluster 8. It is built from four matters this guide has decided to look at side by side: the brand, the Gambling Commission remote licence number and the licence holder behind it, and what each operator’s own terms state on the offer’s structure. Several matters would have added a column with a single value repeated down most rows, so they were dropped. None of the brands below is “the only licensed one” — the Commission’s register lists more than the ten this page covers.

A reader comparing this table should look at three places. The first is the licence number itself — the Commission’s public register is the one test of whether the licence is real and current, and the snippet the table carries is a fingerprint, not a vote of confidence. The second is the licence holder: several of the well-known brands sit under the same parent (Ladbrokes and Coral under LC International Limited, for example), and that fact changes nothing about how the offer is governed. The third is the offer structure. Some of these brands — BetUK, Hollywoodbets, Sporting Index, Spreadex — quote the welcome offer in full because the terms are unusually specific. Others quote the feature list because the welcome offer’s headline figure rotates faster than the print cycle of any guide. A reader who wants the headline figure goes to the brand’s own page on the day; this guide describes the shape of the offer, which is what does not change between promotions.

What a free bet actually is — and what the offer covers

The cleanest definition: a free bet is a credit the bookmaker credits to a customer’s account that lets the customer place a real bet without risking their own cash on the stake. The winnings land in the account. The stake, in nearly every case, is not returned with the winnings. That single rule is the difference between a free bet and a refunded stake, and the marketing language does not always make it clear which one the punter is holding.

The four shapes a free-bet offer takes

Sign-up offers come in four shapes, and they cost different amounts to clear. The first is the matched free bet: deposit a stake, place a qualifying bet, and the bookmaker credits a free bet of equal or greater value. Coral and Unibet’s “bet £20, get £40” is the working example, with a minimum price of 2.0 on the qualifying bet and a 7-day expiry on the credit. The second is the stake-back as a free bet: place an accumulator, lose, and the bookmaker returns the stake as a free bet. Hollywoodbets’ £30 stake-back on a first losing acca is the working example. The third is the bet-and-get bundle: deposit, place a small qualifying bet, and the bookmaker credits several free bets at once (BetUK’s four £10 free bets, Sporting Index’s £10 free bet plus three spread-bet credits). The fourth is the deposit bonus: a percentage match on the deposit, paid as a bonus that carries a wagering requirement. The last shape has been adjusted by the Commission’s recent promotion rules — see the section on the rules for the figures.

What “wagering requirement” actually means

A wagering requirement is a multiplier the bookmaker applies to a bonus, and it tells the customer how much of their own money they must stake before the bonus — and any winnings on it — can be withdrawn. A £10 bonus at 1x wagering requires £10 of qualifying bets; at 5x, £50; at 10x, £100. The Commission’s recent promotion rules cap that multiplier at 10x for any bonus offered to a British customer. That cap is not the only rule — mixed-product promotions (an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery) are banned outright. What the cap does not cover is whether it applies to free bets with no wagering condition. The Commission’s published guidance does not establish that point, and the writer of this page does not invent the answer. Free bets with no wagering condition should be read on their own terms.

The minimum price and the qualifying bet

Almost every welcome offer attaches a minimum price to the qualifying bet. Coral and Unibet use 2.0 (1/1); Betway uses 1.75; Sporting Index and Spreadex use 1.50 (1/2); Sky Bet free bets themselves are usable on single or each-way markets at the operator’s own minimum. The minimum price is not an arbitrary threshold. It stops the customer from laying the qualifying bet on a heavy favourite at odds of 1.05 and treating the offer as a strategy to secure the credit without accepting the market risk the bookmaker intends. The bookmaker sets it where it forces a real bet, and a punter who wants to clear the offer at minimum cost reads the small print for the price the bookmaker requires.

The shape of the British market — what the offer is worth in cash

A reader asking what a free bet is worth is asking the right question. The headline figure is the offer’s marketing price; the realised value is what lands in the account after the offer’s rules have done their work. The two are not the same, and the section below sets out the relationship between them.

The free-bet-value calculation

For a free bet whose stake is not paid back, the realised value depends on three things: the free-bet amount, the price the customer takes, and the bookmaker’s margin on the market they bet into. The formula: value = free-bet amount × (odds − 1) ÷ odds × payout share of the market. Worked example with a £10 free bet on a two-way market at decimal odds 1.90 / 1.90 (fractional 9/10), where the payout share at those prices is 1 ÷ (1/1.90 + 1/1.90) ≈ 0.526, the margin is 1 − 0.526 ≈ 0.474 (about 47%), so on average a bet on either outcome returns 52.6p per £1 staked. The free bet is worth £10 × (1.90 − 1) ÷ 1.90 × 0.526 ≈ £2.49 on average — a band of roughly £2 to £3 depending on the market the customer chooses. The price is an illustration, not a quoted market; the figure to remember is the shape: a £10 free bet at this market returns about a quarter of its face value in expected winnings. At a higher price the band moves up sharply; at a tighter market the price much widens. Calculating the offer’s value involves running the arithmetic on the intended price.

What “stake not returned” means in the account

A £10 free bet at decimal odds of 3.00 on a winning selection pays £20 — that is the winnings, not the return. A £10 cash bet at the same odds would pay £30 — that is winnings plus stake. The £10 difference is the cost of using the credit, and it shows up in every comparison between a free bet and a refunded stake. A “risk-free” offer that refunds a losing stake as a free bet is not a refund in money; it is a credit that carries the same stake-not-returned rule as any other free bet. The marketing word is one thing; the line in the account is another. A reader comparing offers reads the settlement line, not the headline.

Why the calculation is a band, not a single figure

The worked figure above is a statistical estimate, an average over many bets on a market at the stated prices. No single bettor at a single bookmaker realises that figure on a single bet; the realised value depends on which way the bet wins and which market the customer chose. The number to take from the calculation is the band — roughly £2 to £3 on the example — and the insight that the band widens at higher prices and narrows at lower ones. A free bet on a 4/1 shot is worth more than one on an even-money favourite, in expected terms, because the larger profit on the win multiplies through a smaller payout share. A reader who treats the figure as a guarantee will be disappointed; a reader who treats it as a measure of which offer is worth claiming will find it useful.

The legal frame — what the Gambling Commission does and does not allow

The British market runs under the Gambling Act 2005, and the Gambling Commission is its regulator. The framework below is not a section of law the reader has to memorise; it is the answer to the practical questions that come up when a free bet lands in the account and the punter wonders who is on their side.

The licence and what it covers

Every operator this page reviews holds a remote general betting standard (real events) licence issued by the Commission. The Commission’s public register is searchable by business name, trading name, domain or account number, and it is the test of whether a brand holds a current licence. Since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based (sections 33 and 36 of the 2005 Act as amended); a Curaçao, Maltese or Gibraltar licence is not a substitute. The Commission’s remit covers Great Britain — England, Scotland and Wales. Northern Ireland is outside the 2005 Act and runs its own older framework; a “GB licence” regulates Great Britain and not Northern Ireland, and the page does not write otherwise. There is no state monopoly and no cap on the number of licences. Several well-known brands sit under the same licence holder (Ladbrokes and Coral under LC International Limited; Paddy Power and Betfair under PPB Counterparty Services Limited), and they are not independent operators for the purposes of this guide.

Identity, age and the moment a customer opens an account

Every licensed remote operator verifies the customer’s name, address and date of birth before the customer can deposit or gamble. That has been the rule since 7 May 2019 and it covers free bets and bonuses — there is no anonymous play at a licensed site, and no way to test a free bet without going through the same checks a deposit would attract. Minimum age is 18. The financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) is a separate step: once a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025), the operator runs a public-record check — bankruptcy, county court judgments — not an income check and not a credit reference check. The financial risk assessments sometimes called “affordability checks” are announced, staged, and have no published start date; this guide does not write them as if they were in force.

Credit cards and the payment ban

Credit cards are banned for gambling in Great Britain — since 14 April 2020, under LCCP condition 6.1.2 — and the ban covers credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered. Coral’s site, for example, lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options, with the qualification that the welcome offer must be qualified with a debit card or instant bank transfer. There is no British named-account rule, no state list of permitted payment methods and no rule for or against cryptocurrency deposits at licensed operators; the page describes payments qualitatively and only from each operator’s terms.

Tax — the operator’s, never the punter’s

The player pays no tax on betting winnings in Great Britain (this is general information, not tax advice; a professional gambler should ask HMRC or a tax adviser). General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Until 1 April 2027 the remote rate stays at 15%; whether operators pass duty on through odds is not established, and this guide does not write that the player is charged duty.

The promotion rules in force since 19 January 2026

Two rules govern the offer itself. The first caps wagering requirements on bonuses at 10x — a £10 bonus at 50x would need £500 of qualifying bets; under the cap no more than £100. The second bans mixed-product promotions, offers that require gambling on two or more product types such as betting, casino, bingo and lottery. The 10x cap is the headline figure; the mixed-product ban is the structural change. What neither rule establishes is whether the 10x cap applies to free bets with no wagering condition — a free bet that does not need to be re-staked before withdrawal — and whether there is any cap on the money value of a bonus. The Commission’s published guidance does not settle those points, and the writer of this page does not settle them either.

Responsible gambling — the tools and the protections

The licensed operators this guide reviews carry a set of safer-gambling tools by condition of their licence. The section below sets out what those tools do, where the line falls between operator duty and customer choice, and where a punter in distress should turn.

GAMSTOP — the multi-operator self-exclusion

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Self-exclusion periods are six months, one year, five years, or five years with auto-renewal. After the minimum period, the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service. The scheme is the strongest practical protection a British customer has against opening new accounts under stress, and a licence holder that fails to enrol a self-excluded customer faces regulatory action.

Deposit limits, loss limits and wagering limits

Deposit limits are mandatory under the Commission’s Remote Technical Standards (RTS 12): operators must offer a gross deposit limit on a fixed time frame. The first changes have applied since 31 October 2025; a second phase was postponed to 30 September 2026, and whether the second phase is live is not established in the public record at the time of writing. DAZN Bet, for one, lists deposit limits, loss limits and wagering limits among its safer-gambling tools. There is no state-set deposit or loss ceiling for betting — limits are the customer’s choice. The licensed operators’ tools are the customer’s to set.

Help and where to find it

GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. NHS gambling clinics operate in several regions. Gamblers Anonymous runs peer-support meetings. The contact details for each are on their own sites; the section above is the place to start when the question stops being about offers.

Bonuses and free bets — the offer in detail

The section above covered the framework. The section below covers the detail: what each welcome offer asks of the customer, what each one pays out, and where the small print changes the headline.

Coral — “Get £40 in Free Bets when you bet £20”

Coral’s offer is the cleanest in the licensed set. A deposit and a sports bet of £20 or more, at minimum odds of 2.0 (1/1), returns £40 in free bets within 7 days, expiring 7 days after issue, for new GB customers who opt in. The qualifying payment must be a debit card or instant bank transfer. The credit is non-withdrawable and the stake is not returned. The site pairs this with a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games such as Football Super Series with a £10,000 jackpot. Coral sits under LC International Limited alongside Ladbrokes — the parent has been in the British market since the high street era, and the app’s feature set reflects that. For a customer who wants a flat-rate matched credit and a strong acca product, Coral’s terms read in full.

Unibet — “Get £40 in Free Bets when you bet £20”

Unibet runs the same headline as Coral and a structurally similar offer: a deposit and a sports bet of £20 or more, at minimum odds of 2.0 (1/1), with free bets expiring within 7 days of issue, for new GB customers using a debit card or instant bank transfer. Unibet’s app adds Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets. Unibet states it has operated since 1999, and its UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The free-bet offer is a matched credit, not a refund; the credit is non-withdrawable and the stake is not returned.

BetUK — four £10 free bets on a £10+ qualifying bet

BetUK’s sports welcome offer is a deposit of £10 or more and a sports bet within 7 days of registering, returning four £10 free bets — two football accumulators of 4+ selections and two multiples of 2+ — each valid for 7 days, opt-in required. The structure splits the credit into four pieces rather than one, which raises the chance the customer uses all of it inside the window (each piece expires on its own clock). For a customer whose betting concentrates on football accas, the structure fits; for a customer who bets singles across sports, the structure is more pieces than they will use. BetUK’s licence holder is LeoVegas Gaming PLC, the parent runs a casino-led group, and the sportsbook is a thinner overlay on top.

Hollywoodbets — stake back as a free bet on a first losing acca

Hollywoodbets’ offer is the only stake-back shape in the top ten. New players who deposit £10 or more by card get their stake back as a free bet of up to £30 on their first qualifying losing accumulator (stake £10+, 3+ legs, odds of 4/1 or greater, settled within 7 days); one free bet per customer. The structure is right for a customer who backs accumulators and is comfortable with a three-leg minimum at combined odds of 4/1. The credit is non-withdrawable and the stake is not returned. Hollywoodbets’ licence holder is Hollywoodbets International UK Limited, the brand runs from a South African racing heritage, and the UK product is a focused one rather than a broad menu.

Spreadex — £60 in free bets for a £10 fixed-odds bet

Spreadex runs a hybrid offer that is unique among the top ten. A £10 qualifying wager at minimum odds of 1/2 (1.50) unlocks £60 in free bets, usable across fixed odds and spread betting; the qualifying bet must be placed within 28 days of opening the account. The offer’s size reflects the hybrid product, and a customer who understands spread betting will read the credit differently from one who does not. Spreadex’s app adds Acca Boosts — cash from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs.

Sporting Index — fixed-odds and spread-bet bundle

Sporting Index’s welcome offer splits a £10 fixed-odds stake at minimum odds of 1/2 (1.50) into 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 rewards a customer who wants the spread-bet side of the product; for a customer who only bets fixed odds, half the credit sits unused. Sporting Index’s licence holder is Sporting Index Limited, and the brand’s heritage is in spread betting.

Sky Bet — the terms that matter

Sky Bet free bets expire 30 days after crediting, can be used only on single or each-way markets (not multiples) excluding virtuals, are non-withdrawable and do not return the stake with winnings. The 30-day window is generous against the 7-day window most of the rest of the licensed set uses. The singles-only restriction is restrictive against the acca-heavy customer. Sky Bet’s app and feature set pair the credit with Best Odds Guaranteed on UK and Irish racing, acca boosts on football and Super Boosts on selected matches. Sky Bet does not appear in the operator ranking this guide ships from, but the terms are the cleanest example of the singles-only and stake-not-returned rules in the licensed set, and a reader comparing offers reads them as the benchmark.

Other operators in the licensed set

Dabble’s welcome offer is “Bet £10, Get £10 in Free Bets” on a first deposit for new customers, with minimum odds applying, a 7-day free bet expiry and the stake not returned. Betway’s minimum deposit is £10, and free bets carry 1x wagering at odds of 1.75 or higher. Betfair Sportsbook offers in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football within the app, and a 90 Minute Payout market. Ladbrokes offers odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish horse races, in-play betting and Acca Boosts. QuinnBet free bets are valid for 7 days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed. William Hill’s Football Acca Boost covers accas of 2+ legs with each selection at 1/5 or bigger, scaling from 3% on a double up to 200% on 20+ legs, capped at £10,000 per online bet, running until 30 May 2027. bet365 offers Bet Builder+, Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. Midnite’s site cites Gambling Commission licence 101839 and shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. Kwiff’s Supercharge feature can instantly boost the odds on a bet — for example from 2/1 to 20/1 — on single or multi bets on any sport. Star Sports offers pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts.

The shape of the offer after the rules

The 10x cap on wagering requirements and the ban on mixed-product promotions have reshaped the welcome offer across the licensed set. A reader comparing offers in 2026 should look for two things. The first is the wagering multiple on any bonus (not free bet) component of the offer — anything above 10x is no longer permitted at a licensed operator. The second is the structure of the offer: a free bet is a credit whose stake is not returned; a stake-back is a refund in credit form; a deposit bonus carries wagering requirements. The marketing word and the realised value are still different things, and the rules in force since 19 January 2026 have brought the realised value closer to the headline without closing the gap.

Payments and payout speed — what sits between the offer and the account

The offer credits the free bet; the payment method credits the winnings. The two are not the same step, and the speed of the second depends on the first.

Deposits and the welcome-offer qualification

Coral’s terms state that the welcome offer must be qualified with a debit card or instant bank transfer; Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly are among the payment options on the site, but the qualification requires the first two. Hollywoodbets’ offer must be qualified by card deposit. The pattern across the licensed set is that the welcome offer carries its own payment-method condition; the deposit methods listed on the site’s cashier page are wider than the methods that qualify for the credit. Verifying the offer details requires checking the brand’s own terms for the qualifying payment line; this guide outlines the structure, acknowledging that the precise live list changes frequently.

Withdrawals and the time it takes

Debit-card withdrawals at the licensed operators settle on the same business day or the next business day for most of the major brands; bank transfers take one to three working days; e-wallets settle within hours once the operator has processed the request. The processing state is the operator’s queue, not the payment system’s; a request made on Friday night will not leave the operator’s queue until Monday morning in most cases. The free-bet winnings are subject to the same withdrawal rules as cash winnings; nothing about the credit changes the rails on which the money moves.

What the rules say about payments

The credit-card ban of 14 April 2020 covers credit-card-funded payments through an e-wallet; debit cards and bank-based payments are not covered. There is no state list of permitted payment methods, no British named-account rule and no rule for or against cryptocurrency deposits at licensed operators; the page describes payments qualitatively and only from each operator’s terms. A reader who wants the live list goes to the cashier page; a reader who wants the framework reads the rules above.

Predictions and strategy — what a free bet cannot do for the punter

The honest answer to the question of which bets a free bet should be placed on is the one the betting industry would rather the reader did not hear. A free bet does not change the probability of the selection winning. The bookmaker’s margin sits inside every price; the marketing word does not move it. The section below sets out what a free bet does and does not change about a bet.

The bookmaker’s margin and what it costs

For a two-way market at decimal odds of 1.90 / 1.90, the payout share is 1 ÷ (1/1.90 + 1/1.90) ≈ 0.526 — that is, 52.6p of every £1 staked across both outcomes comes back to customers on average. The margin is 1 − 0.526 ≈ 0.474, or about 47%. That is what the bookmaker keeps of every unit bet on this market. The margin changes from market to market and from bookmaker to bookmaker; a Premier League match at a sharp bookmaker carries a tighter margin than a novelty market at a soft one. Knowing the margin requires checking the price on the two or three outcomes and doing the calculation. Minimising the cost of using a free bet involves seeking out markets where the margin is tightest.

Why “free” is a misleading word

The free bet is not free; it is a credit whose stake is not returned. The realised value on a £10 free bet at the worked example above is about £2.49 on average, depending on the market chosen. The headline figure is the offer’s marketing price; the realised value is what lands in the account. The two are not the same, and the reader who treats them as the same loses money on the difference. The calculation above is the bridge between the two.

What predictions and tipsters can and cannot do

A prediction service cannot tell a reader who will win. Nobody can. A reader who acts on a predicted outcome loses real money on the page that predicted it. The free-bet offer and the prediction are independent: the offer’s value depends on the price and the market’s margin, and the prediction’s accuracy depends on a set of factors that nobody can see through. A reader who treats the two together — placing a free bet on the tipster’s pick in the belief that the combination beats both — is paying the margin for the tipster’s certainty as well as the bookmaker’s. The honest framing is the one the betting industry does not sell: a free bet is a marketing credit, and the price on the selection is the price on the selection.

The expected cost of using the offer

For a bonus with a wagering requirement, the expected cost is the required turnover multiplied by the margin of the market the customer bets into. For a £10 bonus at 10x wagering on a market at 5% margin, the expected cost is £100 × 0.05 = £5; on a 10% margin, £10. The Commission’s 10x cap is the ceiling on the turnover; the margin is the operator’s choice and the market’s choice. A reader who wants the cost in cash works the arithmetic on the market they intend to use. For those looking for the most efficient path, choosing the tightest market available minimises the cost of clearing the bonus.

What the strategy looks like in practice

A reader using a free bet at a two-way market at decimal odds of 1.90 / 1.90 realises about a quarter of the headline value on average. A reader using the same free bet at decimal odds of 5.00 / 5.00 on a market with a payout share of about 90% realises more, because the higher price multiplies a larger profit onto a stake the bookmaker has not returned. The trade-off is the punter’s confidence in the selection: a 5.00 shot is less likely to win than a 1.90 shot, and the realised value is an average over many bets. The reader who treats the calculation as a guarantee on a single bet is misreading it; the reader who treats it as a measure of which market is worth using is reading it right.

The operators, reviewed

Each review below closes on a judgement of the brand. The specifications above it do not make the judgement — the writer of this page does. Each review uses the same angle but reaches its own verdict.

BetUK — a focused sportsbook on a casino-led base

BetUK sits under LeoVegas Gaming PLC, a parent whose roots are in casino. The sportsbook is a thinner overlay on top: a strong football product, a smaller horse racing menu, and a four-piece free-bet structure rather than a single matched credit. The credit structure rewards a customer whose betting is football-led and acca-led; the customer who bets singles across several sports will leave pieces of the credit unused. The 7-day window on each piece is tight against Sky Bet’s 30 days, and the customer who signs up during a quiet week in the calendar will find the window harder to fill. Verdict: a sensible welcome offer for the football-led customer; it is less suited to the punter who spreads their stakes across the wider sports calendar.

888sport — broad feature list, rotating welcome offer

888sport sits under 888 UK Limited, a parent whose name is the brand. The sportsbook carries pre-match and in-play betting, Cash Out, Bet Builder, racing streams, BetFinder form tools, a live bet feed and daily boosted odds. The feature set is broad and the welcome offer rotates faster than this page’s print cycle. The customer who wants the latest 888sales change goes to the brand’s own page; this guide describes the feature set, which does not change between promotions. Verdict: a strong all-rounder for the customer who reads the offer’s terms before claiming and is comfortable with a rotating headline.

Hollywoodbets — the stake-back shape for the accumulator customer

Hollywoodbets sits under Hollywoodbets International UK Limited, the UK arm of a South African racing heritage. The sportsbook’s welcome offer is the only stake-back shape in the top ten: a £30 free bet on a first qualifying losing accumulator of 3+ legs at 4/1 or greater, settled within 7 days, one free bet per customer. The shape fits the customer who backs accumulators and is comfortable with the loss of the first one. The shape does not fit the customer who bets singles or each-way on horse racing; the credit is unreachable for them. Verdict: the right offer for the right customer, and the wrong offer for the wrong one.

BetVictor — long-running brand, rotating offer

BetVictor sits under BV Gaming Limited, a parent that runs both BetVictor and the Heart Bingo brand. The sportsbook’s welcome offer is shown in the app and governed by the customer terms, and the regular price boosts, acca offers and free bets on selected events rotate on the operator’s calendar. The brand has been in the British market since the high-street era, and the online product carries that history without leaning on it. Verdict: a stable choice for the customer who prefers a long-running operator and is happy to verify the specific terms of the day’s offer.

William Hill — Football Acca Boost until May 2027

William Hill sits under WHG (International) Limited, a parent whose name is the brand and whose high-street history is the longest in the top ten. The Football Acca Boost covers accas of 2+ legs with each selection at 1/5 or bigger, scaling from 3% on a double up to 200% on 20+ legs, capped at £10,000 per online bet, running until 30 May 2027. The boost is the operator’s headline product; the welcome offer sits on the app and rotates. Verdict: the right operator for the acca-led football customer who reads the boost terms and is comfortable with the £10,000 ceiling.

Betfair — exchange heritage, sportsbook product

Betfair sits under PPB Counterparty Services Limited, the parent that also runs Paddy Power and the Betfair Exchange. The sportsbook’s feature set pairs in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football within the app, and a 90 Minute Payout market. The sportsbook is not the exchange; the welcome offer on the sportsbook is the one this guide describes, and the exchange’s separate terms apply on the exchange side. Verdict: a strong sportsbook product for the customer who values streaming and the 90 Minute Payout market, and understands that the sportsbook terms are distinct from the exchange.

Sporting Index — the spread-bet welcome bundle

Sporting Index sits under Sporting Index Limited, a parent whose heritage is in spread betting. The welcome offer splits a £10 fixed-odds stake at minimum odds of 1/2 into 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 bundle is the right shape for the customer who wants the spread-bet side of the product; for the customer who only bets fixed odds, half the credit sits unused. The customer who does not understand spread betting should not claim the offer. Verdict: a sensible bundle for the spread-bet user; it is less suited to the fixed-odds-only punter.

Spreadex — the hybrid offer, the FCA-regulated side

Spreadex sits under Spreadex Limited, a parent whose products straddle fixed odds and spread betting. The welcome offer is £60 in free bets for a £10 fixed-odds stake at minimum odds of 1/2, usable across fixed odds and spread betting; the qualifying bet must be placed within 28 days of opening the account. Spreadex is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting, and the site states that spread betting losses can exceed the deposit. The 28-day window is generous against the 7-day window most of the licensed set uses. Verdict: a strong offer for the customer who understands the spread-bet side and is comfortable with the FCA-regulated hybrid.

Ladbrokes — the high-street parent, the broad product

Ladbrokes sits under LC International Limited, the parent that also runs Coral and several other brands. The sportsbook’s feature set pairs odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish racing, in-play betting and Acca Boosts; the welcome offer rotates on the operator’s calendar. The Coral and Ladbrokes brands share a parent; the offers and the apps are separate, and the customer who claims one offer does not forfeit the other’s. Verdict: a stable choice for the customer who wants a long-running operator with a broad feature set, and is comfortable comparing Coral and Ladbrokes as two separate routes into the same parent.

Bar One Racing — the Irish independent, the UK licence

Bar One Racing sits under Bar-One Racing Limited, an Irish independent bookmaker with shops across Ireland and horse racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. The brand has rebranded as BAR 1 Betting. The UK product is a thinner overlay on the Irish core, and the welcome offer is a smaller headline than most of the licensed set in this guide. Verdict: a niche choice for the customer whose betting is horse racing-led and who views the Irish sponsorships as a stamp of credibility; it is less appealing to the punter needing the broad feature set of the larger brands.

Frequently asked questions

What are free bets?

A free bet is a credit the bookmaker places in a customer’s account that lets the customer place a real bet without risking their own cash on the stake. The winnings land in the account. The stake, in nearly every case, is not returned with the winnings, which is the difference between a free bet and a refunded stake. The marketing word and the realised value are not the same thing.

How do free bets work?

A welcome offer credits a free bet once the customer has met the qualifying condition — usually a first deposit and a first bet at a minimum price. The free bet is placed like any other bet on the betting slip. When the bet wins, the winnings land in the account and the stake is not returned. When the bet loses, the customer has lost only the stake’s opportunity cost, not their own cash. The credit is non-withdrawable in nearly every case.

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

The Commission’s recent promotion rules cap wagering requirements on bonuses at 10x. A £10 bonus at 50x would need £500 of qualifying bets; under the cap, no more than £100. The cap applies to bonuses. Whether it applies to free bets with no wagering condition is not established in the Commission’s published guidance, and free bets with no wagering condition should be read on their own terms.

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

A minimum price is the threshold the qualifying bet must reach before the offer credits. A wagering requirement is the multiplier the bonus carries before it can be withdrawn. The two work together: the customer places a qualifying bet at or above the minimum price to unlock the credit, and the bonus (if any) carries the wagering requirement before withdrawal. A £10 bonus at 10x wagering on a market at 5% margin costs about £5 on average to clear; the same bonus on a 10% margin market costs about £10.

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

The free bet’s stake is the credit the bookmaker has given the customer, and the credit is the offer’s headline value. Paying the credit back alongside the winnings would convert the offer into cash, which the bookmaker is not offering. The rule keeps the offer’s cost to the operator fixed and lets the offer’s headline read at the credit’s face value. A £10 free bet at decimal odds of 3.00 pays £20 in winnings; a £10 cash bet at the same odds pays £30. The £10 difference is the cost of using the credit.
