Current as of 27 October 2026; verified against the Gambling Commission’s public register.

A sign-up offer is the bookmaker’s first word to a new customer, and in Great Britain the regulator has tightened what that first word can say. From 19 January 2026 wagering requirements on bonuses are capped at 10x and any offer that pulls a customer across product types (betting and casino together, for instance) is no longer permitted. What sits inside those rules still varies widely: a £40 free bet at one brand may need a £20 qualifying wager at minimum odds of 2.0, a £10 first deposit at another may unlock a £10 token, and at a third a £10 losing acca brings the stake back as a free bet if the bet loses. Every figure on this page comes from each operator’s own published terms, dated to the source snapshot given.

This is the £-number offer at ten GB-licensed brands, what the small print takes off the top, and where the headline price leaves the reader ahead after the maths has run.

Why “free” is doing a lot of work in “free bet”

A free bet is a token, not cash. The defining cost of the mechanism is the one line most readers skim: the stake is not paid back with the winnings. That single rule is the reason a £10 free bet at odds of 3.0 does not return £30. It returns £20 — the £20 of profit, with the £10 stake gone. Two identical offers can therefore have different real values depending on whether the stake is returned, and the difference shows up the first time the bet wins.

Behind that one rule sit three more the small print sets out, and each one trims what the offer is worth:

• A minimum odds floor. The qualifying bet, and often the free bet itself, must be placed at odds above a stated line — 1.5 (1/2), 1.75, 2.0 (1/1), 3.0 — and that floor exists because low odds on heavy favourites leave almost no edge for the reader. The free-bet token at minimum odds of 1/2 is worth less than the same token at 2.0, because the price that locks in profit has to climb.
• An expiry window. A free bet that expires in 7 days is worth less than one with 30 days, because the bet force has fewer chances to find a price worth taking. The pace of the offer is the pace at which the reader must act.
• A market restriction. Several brands let free bets go only on singles or each-way markets, not multiples. Others let accumulators in but exclude Trixies, Patents and Yankees. The allowed bet types shape which prices the reader can target.

Then there are offers that look different in kind but follow the same shape. A matched bonus adds to the balance but carries a wagering requirement — a multiple on which the bonus (or the bonus plus the deposit) must be turned over before any of it can be withdrawn. A “risk-free” first bet refunds the stake as a free bet if it loses, which is not a refund in money but a token under the same rules. A price boost raises the odds on a chosen selection; its value depends on whether the boosted price carries a stake-returned rule or not.

The arithmetic that ranks these is not complicated, and it is worth doing once before any brand is picked.

What a free bet is worth on average

Take the standard case: a free bet whose stake is not paid back, on a two-way market priced at 1.90 / 1.90. The payout share on that market, before the bookmaker’s margin, is 1 ÷ (1/1.90 + 1/1.90), which works out to 0.95 — a 5% margin. The free bet wins half the time on a fair line, returns the £20 of profit on a £10 token at 3.0, and on average produces roughly £9.50 of value over many such bets (free-bet amount × (odds − 1) ÷ odds × payout share = £10 × 2 ÷ 3 × 0.95 ≈ £9.50, with the precise number tracking the price and the market margin). Move the same £10 token to a price of 2.0 and the average value drops; move it to a price of 5.0 and the average climbs. The headline offer of “£40 in free bets” is therefore not £40 of value — under ordinary conditions and at modest prices, it lands somewhere around £35–38 against the headline, before any market restriction, expiry or stake cap is layered on.

Two corollaries follow. First, a free bet at high odds with no market restriction and a long expiry is the most generous shape the mechanism allows. A short-expiry token restricted to favourites is the least. Second, the size of the headline number is a poor guide on its own; what sits underneath it (the minimum odds, the markets allowed, the expiry) decides whether the offer earns its place.

The 10x cap in plain English

The Commission’s promotion rules in force since 19 January 2026 set a hard ceiling on how much a customer must wager to clear a bonus: no more than ten times the bonus amount. A £10 bonus can require at most £100 of betting before any withdrawal; a £50 bonus, at most £500; a £100 bonus, at most £1,000. That ceiling is the single biggest change to British sign-up offers in years and it rules out, on its face, the heavy-multiplier bonuses that were once common offshore.

Whether the 10x cap also applies to free bets with no wagering condition was not established by the regulator’s published guidance. Where the offer is a free bet whose winnings are withdrawable (subject only to a stake-not-returned rule, an expiry and a market restriction), the cap does not bite in the same way; where the free bet winnings are themselves treated as a bonus and must be re-wagered, the cap is the upper bound on that re-wagering. Reading the specific brand’s own terms is the only way to know which shape an offer takes.

The legal frame a British reader stands inside

Every brand named in this article holds a Gambling Commission remote licence for Great Britain. The licence is the operator’s permission to take bets from customers in England, Scotland and Wales; Northern Ireland runs its own older law, and a GB licence does not cover it. Since the Gambling (Licensing and Advertising) Act 2014 any operator whose remote facilities are used in Great Britain must hold a Commission licence wherever it is based — a Curaçao, Maltese or Gibraltar licence is not a substitute at the point of consumption.

The Gambling Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport, and it regulates under the Gambling Act 2005. There is no state monopoly and no cap on the number of licences, so the British market is one of the most open in Europe; that openness is also why a register check, not a brand reputation, is the right first move.

The Commission’s public register can be searched by business name, trading name, domain or account number, and the entry there is the test of whether a brand holds a licence at all. Domains tell the reader little: licensed operators use .com as well as .co.uk. The register is the place to confirm, before any deposit, that the brand named on the offer page is the licence holder it claims to be.

Two licences matter for the offers on this page. Remote general betting standard (real events) covers fixed-odds sports betting with a real-world outcome. Remote betting intermediary covers betting exchanges — a different business, in which the operator matches back and lay bets between customers rather than taking the other side itself. Several brands on this page sit under one licensee, which is why a licensee’s name and a brand’s name are not always the same word.

What the rules require before a bet is placed

Identity verification runs before the first deposit at a GB-licensed site. Since 7 May 2019 name, address and date of birth have to be confirmed before a customer can deposit or gamble, and that includes placing a free bet or activating a bonus. Anonymous play is not an option at a licensed bookmaker; offshore operators, where no GB licence applies, do not run the same check.

Once a customer is in, the Commission runs a layered set of safer-gambling controls. GAMSTOP is the national multi-operator self-exclusion scheme, mandatory for online operators since 31 March 2020, with exclusion periods of 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.

A financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025). It is a public-record check — county court judgments, bankruptcies and the like — not an income check and not a credit reference check. The deeper “financial risk assessments” sometimes called affordability checks have been announced in a staged plan (a Commission article of 7 July 2026) with no start date, and the right way to describe their status is “announced, staged, no start date”.

Deposit limits sit under Remote Technical Standard 12. Operators must offer a gross deposit limit on a fixed time frame. The first phase has applied since 31 October 2025; a second phase has been postponed to 30 September 2026. No state-set deposit or loss ceiling exists for betting: limits are the customer’s choice, and the operator’s job is to make the limit-setting controls visible.

Credit cards are banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2), and that ban extends to credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not caught by it. E-wallets such as PayPal, Revolut Pay, Apple Pay and Google Pay, plus bank-transfer services such as Trustly and TrueLayer, are accepted at most licensed brands and are not, on their own, restricted by the credit-card ban.

Tax, advertising and the offshore boundary

The player pays no tax on betting winnings in Great Britain; that is general information, not tax advice, and a professional gambler should ask HMRC or an 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-self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Whether operators pass duty on through odds is not established; the right framing is that the duty is the operator’s cost, not the player’s charge.

Advertising is not licensed by the Commission. It runs through the CAP Code (non-broadcast) and the BCAP Code (broadcast), enforced by the ASA, alongside the Commission’s LCCP marketing conditions. CAP Code section 16 requires marketing to be socially responsible, not of strong appeal to under-18s, and it sets a rule that no one who is or seems to be under 25 may be featured gambling or play a significant role — with an exception for marketing placed where a bet can be made directly. That rule concerns who may appear in an advertisement, not who may bet.

The “whistle-to-whistle” rule is an industry code, not statute: since 1 August 2019 betting advertisements are not shown on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed, with horse and greyhound racing excluded. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts (from 2026/27; sleeves and hoardings remain) is voluntary, not law.

Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005 (on summary conviction up to 51 weeks’ imprisonment, a fine up to level 5, or both; six months in Scotland) — aimed at the operator. No offence aimed at a customer who merely bets on an unlicensed site was found in the regulator’s published material. The loss of protection — no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and no application of the 10x bonus cap or the £150 vulnerability check — is the right framing for an offshore site. Enforcement against unlicensed operators is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and the court-order DNS blocking powers the regulator has been given or is about to receive. ISP-level blocking is not, at the time of writing, in operation.

Responsible gambling: what the controls actually do

GAMSTOP, GamCare, the National Gambling Helpline, GambleAware and the NHS gambling clinics are the named routes a customer has in Great Britain. Each does a different part of the work, and the controls sit on top of the operator’s own deposit, loss and wagering limits, which DAZN Bet and several other operators make visible inside the account page.

GAMSTOP is the multi-operator self-exclusion register. Once a customer signs up, every licensed online operator is required to refuse their account for the chosen period. It covers online sites and apps; betting shops run a separate service. A self-exclusion is not a pause, and the minimum period is six months; an exclusion taken for a year does not unlock until the year is up, and an exclusion taken for five years stays in place for five unless the customer asks GAMSTOP to remove it (and even then, a further seven years is the minimum if a removal request follows the exclusion period).

The operator’s own deposit, loss and wagering limits are the routine route. A customer sets them inside the account, they apply across the brand’s products, and they are independent of GAMSTOP. Most operators offer time-out periods (24 hours to several weeks) for a shorter break; GAMSTOP is the heavier lever.

The financial vulnerability check is a different kind of control. It runs against public records when a customer’s deposits minus withdrawals cross £150 in a rolling 30 days, and its purpose is to flag a customer who is in financial difficulty in a way that the operator’s marketing data alone would not catch. It is not a credit check and it is not an income check; the operator cannot use it to decide whether a customer can afford to bet in any granular sense. The deeper “financial risk assessment” framework the Commission has announced is the next layer, staged and with no start date.

GamCare runs the National Gambling Helpline (0808 8020 133, daily) and a network of treatment services. GambleAware funds research, treatment and public education. The NHS runs specialist gambling clinics across England. Gamblers Anonymous runs peer-support meetings.

Limits, exclusions and check-ups are the controls a licensed operator has to offer, and the brand-by-brand choice on this page is among operators that have to offer all of them. Picking between them on safer-gambling terms is a near tie.

What the sign-up offers actually look like

The shape of a GB sign-up offer in 2026 has converged on a few templates. A “Bet £X, Get £Y in free bets” headline is the dominant one: the qualifying bet carries a stake floor (£10 or £20), a minimum odds floor (1.5, 1.75, 2.0 or 3.0), and a market restriction; the free bet that follows has its own minimum odds, its own expiry and its own stake-not-returned rule. A second template adds a refund: a “bet refund if it loses” offer credits the stake back as a free bet (not cash) when the first qualifying bet loses, capped at a stated figure. A third template layers a casino bonus on top of a sports free bet; under the 19 January 2026 promotion rules, mixed-product promotions are no longer permitted at GB-licensed brands, so the layered template is largely confined to casino-style welcome packages at brands that hold both licences, and the sports-only sign-up sits cleanly on its own.

Across the ten operators reviewed below, the offer types break down roughly as follows:

• Matched free bet (most common). Stake the qualifying amount, receive free bets at a stated value. Coral, Unibet, Betway and Smarkets (through SBK) sit in this shape.
• Stake-back free bet on a losing acca. Hollywoodbets returns the stake as a free bet if the first qualifying acca loses; one free bet per customer.
• Risk-free first bet, refunded as a free bet. A handful of brands run this shape — the refund is a token, not money.
• Bonus plus free bet. A small matched deposit bonus sits beside a free bet. The 10x cap on wagering is the constraint.
• Enhanced odds on a first bet. A boosted price on a named selection, with the stake returned as cash on a win but the stake not returned as part of a free bet.

The differences between offers at this scale are not in the headlines; they are in the small print. The £40 headline at Coral and at Unibet both say “Bet £20, Get £40 in free bets”; what sits behind that headline differs in the qualifying market, the minimum odds on the free bet, the expiry and the markets the free bet can be used on.

A worked example from one offer

Betway’s new-customer offer, as listed in its App Store entry, is £40 in free bet tokens (4 × £10) credited on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit card deposits only. The headline value is £40; the realisable value, on the formula above and at the 2.0 minimum, is £40 × (2.0 − 1) ÷ 2.0 × payout share, which lands in the high £30s before any market restriction or expiry bite. The 7-day expiry is the binding constraint, not the headline figure: in a slow week the bet force has fewer chances to find a price at 2.0 or above worth taking.

A first deposit through a customer who already has a price in mind will find the 7-day window generous; a first deposit through a customer who waits for a price to develop will find it tight.

The ten reviewed bookmakers

The brands below are listed in a set order, not ranked from best to worst. A licence and a sign-up offer are not the same as a fit for a particular customer; the verdict at the foot of each write-up takes a position on that fit.

Swifty Sports — best-odds and streaming built in

Swifty Sports sits under Swifty Global (UK) Ltd and holds a remote general betting standard (real events) licence, account 58957 on the Commission’s register. The App Store entry lists Best Odds Guaranteed, Cash Out on markets including horse racing and football, daily price boosts, live streaming and in-play betting; Bet Builder is marked as coming soon. A welcome offer is not in the listed terms; the brand’s own page is the place to check the current shape.

The relevant comparison for a customer choosing between brands on this list is that Swifty’s in-app feature set looks fuller than several of the others — Best Odds Guaranteed on horse racing is rare among newer brands, and live streaming bundled with in-play betting is closer to the established bookmakers’ offer than to the smaller ones. The trade-off is a thinner sign-up headline: the absence of a stated free-bet welcome in the listed terms means a customer looking for a token on day one is being offered the BOG, the stream and the in-play package, not the £40 headline.

Swifty fits a customer who values racing terms and streaming over the size of the welcome token, and who is happy to skip the matched-free-bet shape.

BetGoodwin — three tokens, small print, racing flavour

BetGoodwin runs under Goodwin Racing Limited, Commission account 2927, with the standard remote general betting licence. The App Store listing sets out a Bet £10 & Get £15 in Free Bets welcome split across three tokens: a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The split is the unusual part; a free bet split across three bet types restricts where it can be used, and each token expires on its own clock.

The £15 headline against a £10 qualifying bet is competitive on the face of it. The cost sits in the three-token structure: a customer who prefers singles will leave the acca token stranded, and a customer who prefers multiples will leave the singles token stranded. The Sub-Cover bet is a market-specific token whose eligible events sit inside the brand’s own racing card. Realised value, on the standard formula and assuming all three tokens are used, lands in the £13–14 band on a quiet week and a touch higher on a week where a strong acca price comes in.

BetGoodwin fits a customer who bets across singles, accumulators and the racing-specific market, and is happy to use three tokens rather than one.

Betboro — small match, tight qualifying line

Betboro is operated by Webmedia Development N.V. under Commission account 44181. The site’s terms state a 100% matched free bet up to £25 on the first qualifying wager; a £10 debit card deposit and a £5–£25 first bet with at least three selections at 3/5 (1.60) or higher. The “three selections or more” line on the qualifying bet is the binding constraint; a customer who wants a singles-only first bet does not qualify.

The headline matches the £25 cap on the free bet, and the £10 minimum qualifying stake is the floor. The £25 ceiling is below the £40–60 headline range several other brands offer, and the three-selection minimum on the qualifying bet raises the effective entry cost. A £10 acca at 1.60 per leg, with three legs, prices at about 4.10 in decimal, and a £25 stake-returned-free bet at that price would clear £102.50 of profit at a fair margin — the offer is closer in kind to a token for a customer comfortable placing small accas than to a headline-driven welcome.

Betboro fits a customer whose first bet is already going to be a small acca and who wants a free bet on top.

Coral — large headline, familiar small print

Coral is one of the longest-running high-street names now operating as LC International Limited’s online brand, Commission account 54743, with both remote general betting standard (real events) and remote betting intermediary licences. The welcome offer, “Get £40 in Free Bets when you bet £20”, requires a £20+ deposit and sports bet at minimum odds of 2.0 (1/1); the £40 in free bets is issued within 7 days and expires 7 days after issue; qualifying deposits are debit card or instant bank transfer. The site lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among the payment options.

Coral’s headline is the £40 figure; the cost sits in the 7-day expiry on the free bet, the 7-day window to issue it, and the credit-card exclusion on the qualifying deposit. Beyond the welcome, the brand runs a free daily Reward Shaker, an Odds Booster across hundreds of markets, and free-to-play games including Football Super Series with a £10,000 jackpot.

Coral fits a customer who wants a £40 headline on a familiar name with a wide payment menu and a long-running in-app rewards scheme, and who can place the qualifying bet at 2.0 inside the window.

Geoff Banks — racing-shape book, no stated welcome

Geoff Banks is published by GB Sports Advisors Limited under Commission account 54095. The App Store entry describes an app built around live in-play prices and ante-post prices on future events; no welcome offer is listed in the published terms. The brand’s own site is the place to check the current offer shape.

The Geoff Banks model is closer to a specialist racing book than to a generalist sportsbook, and the ante-post focus sits at the front of the brand’s positioning. A customer who came for the welcome offer finds the table thin; a customer who came for the ante-post market finds the brand sitting in a niche where few others compete at the same depth.

Geoff Banks fits a customer whose interest is ante-post horse racing and who is willing to set aside the matched-free-bet welcome that the other nine on this list offer.

Betway — four tokens, debit-card only

Betway runs under Betway Limited, Commission account 39372. The new-customer offer for UK and Ireland is £40 in free bet tokens (4 × £10) credited on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit card deposits only. The brand’s minimum deposit is £10 across the site, and the free bets carry 1x wagering at minimum odds of 1.75.

The four-token split is the unusual part; a customer who wants to deploy the £40 as a single bet has to consolidate four £10 bets across four events, which is operationally more work than a single £40 token but lets the customer spread the offer across four prices. The 1x wagering at 1.75 on the free-bet winnings is a small re-wagering step before withdrawal; the £150 financial vulnerability check still applies once the customer’s deposits minus withdrawals cross that line in a 30-day rolling window.

Betway fits a customer who can fund the deposit by debit card, who is comfortable placing four £10 free bets rather than one £40 token, and who wants the brand’s wider sportsbook catalogue in addition to the welcome.

Smarkets and SBK — exchange roots, sportsbook shape

Smarkets operates as a betting exchange under Smarkets (Malta) Limited, Commission account 39173, with a remote betting intermediary licence. Its sportsbook arm, SBK, runs the welcome offer: £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours, with Cash Out, Bet Builder and live horse racing streams listed in the App Store entry.

The 3.0 minimum odds on the qualifying bet is the highest on this list, and the £60 headline against a £20 first bet is the largest headline-to-deposit ratio. The trade-off is the price floor: a customer whose first bet was going to be a strong favourite cannot qualify. The exchange infrastructure under the same licence is the brand’s distinguishing feature; a customer who already uses Smarkets’ exchange can hold both products under one account.

Smarkets (SBK) fits a customer with a first bet at 3.0 already in mind, who wants a large headline on the sportsbook side and is interested in the exchange underneath.

Hollywoodbets — refund-on-loss, acca-shaped

Hollywoodbets runs under Hollywoodbets International UK Limited, Commission account 53028. The sports welcome offer refunds the stake as a free bet of up to £30 on the first qualifying losing accumulator, with a £10+ stake, 3+ legs, odds of 4/1 or greater, settled within 7 days; one free bet per customer. The minimum deposit is £10 by card.

The mechanism is a stake-back, not a matched free bet: the customer only receives the free bet if the qualifying acca loses. The cost is the acca shape — three legs at 4/1 or higher prices a small stake into a low-probability bet, and a winning acca at that shape returns the stake as cash plus the profit, with no free bet on top. The free bet is the consolation prize in this scenario, which inverts the usual sign-up shape.

Hollywoodbets fits a customer whose first bet is already going to be a small acca with three-plus legs, and who is comfortable with the “win the cash or get the free bet on a loss” structure.

Octobet — sports free bet plus a small casino layer

Octobet runs under Octopus Game Limited, Commission account 62545. The sports welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers. The “50% back” framing places the offer in the stake-back shape rather than the matched-free-bet shape; the casino bonus is the small extra layer.

The 50% framing caps the realised free bet at half the qualifying stake, and the £10 casino bonus adds a casino-side element to a brand that holds a betting licence. Under the 19 January 2026 mixed-product promotion rules, a layered offer that ties the casino bonus to the sports qualifying bet would not be permitted; the listing here sets the two elements side by side rather than tying them, and the brand’s own page should confirm the shape.

Octobet fits a customer who wants a stake-back on the sports side and is interested in the small casino layer as well, and who is comfortable reading the small print to confirm the two elements are not tied.

10bet — modest headline, daily free bets on top

10bet runs under Blue Star Planet Limited, Commission account 43173. The App Store entry advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins. The 100% matched figure caps the realised bonus at £50, against a £50 minimum deposit, with the daily free bets running beyond the welcome.

The “100% up to £50” headline is a matched-deposit bonus in shape rather than a matched free bet, and the wagering requirement on the bonus is the binding constraint under the 10x cap: a £50 bonus at 10x requires £500 of betting before withdrawal. The daily free bets and free spins are the routine extras; the welcome is the headline.

10bet fits a customer who wants a matched-deposit bonus rather than a free bet, and who is comfortable with the £500 turnover ceiling under the 10x cap to clear the bonus.

How to read the table at a glance

The columns above are brand, licence holder and account number, and welcome offer in the brand’s own terms. The licence holder is the named company on the Commission’s public register, not always the same word as the brand on the app icon; LC International Limited, for instance, runs Coral, and Smarkets (Malta) Limited runs both the exchange and SBK. The “in the brand’s own terms” column transcribes the headline and the binding conditions from each operator’s published material; any free-bet specifics — minimum odds, expiry, market restriction, qualifying deposit method — sit inside the bracket on each row and are the conditions that decide whether the offer is taken.

Two columns a reader might expect are deliberately absent. There is no method minimum-price column because the qualifying-bet minimums vary widely (1/2 at Spreadex, 1.60 at Betboro, 2.0 at Coral, Unibet and Betway, 3.0 at SBK); printing them as a single column would either lose the variation or repeat the headline column. There is no method expiry column for the same reason; the 7-day window dominates, but a few brands run to 30 days and one is “coming soon”. The free-bet conditions sit beside the headline on each row, where the reader needs them.

The comparison that matters

A £40 headline at Coral and at Unibet is the same headline, and the small print on each is in the same neighbourhood: £20+ qualifying bet at 2.0, 7-day expiry, debit card or instant bank transfer to qualify. The headline of £40 against £10 at Hollywoodbets is a different shape entirely — a stake-back on a losing acca, capped at £30, with a 4/1 minimum odds line. The headline of £60 at SBK against £20 at 3.0 is the largest on the table and the most binding on the qualifying bet.

The ranking that a customer builds depends on which constraint matters most to them. A £20 bet at 2.0 is an easier qualifying line than a £20 bet at 3.0, and a £40 token at 7 days is more generous than a £30 refund on a losing acca with a 7-day settlement window. The 10x cap removes the heavy-turnover bonus shape from the table entirely: the matched-deposit bonuses that were once common offshore cannot run above £500 of turnover on a £50 bonus, and several of the offers on this list sit well inside that ceiling.

What the picture looks like to a customer with a £20 budget

A £20 budget covers the qualifying bet at Coral, Unibet, Betway and SBK. It covers the first stake at Hollywoodbets on the same line; at Betboro and BetGoodwin the qualifying stake is £5–£10, with the rest of the budget going into the free bet itself. A £10 budget qualifies the welcome at Betway, Betboro, BetGoodwin and Hollywoodbets, but not at Coral, Unibet or SBK, where the qualifying stake is £20.

The ceiling matters as well as the floor. A customer who wants to deploy £100 across several offers in a week can clear the £10 qualifying stake at most brands and run the £20 qualifying line at Coral, Unibet or SBK once each; the constraint becomes the per-brand identity check, not the stake floor.

What the picture looks like to a customer who bets on horse racing

Best Odds Guaranteed sits at Swifty Sports and at Unibet, and it is the routine offer on the racing side of the larger brands. Live streaming is bundled at Swifty, at Unibet (through Unibet TV) and at SBK. ante-post pricing is the focus at Geoff Banks. A customer who values racing terms above the welcome size finds Swifty, Unibet and SBK offering the routine racing package and Geoff Banks offering the specialist one.

What the picture looks like to a customer who bets on football

Bet Builder and Bet Builder+ sit at bet365, Kwiff, Unibet, Smarkets (SBK), DAZN Bet and others; an acca insurance offer sits at BoyleSports (opt-in, £5 minimum stake, 1/2 minimum odds, £20 maximum refund as a free bet expiring in 7 days, bets placed and settled on the same day). A daily price boost sits at Coral, BetVictor, DAZN Bet and others, with the largest enhanced-odds shape at William Hill’s Football Acca Boost (accas of 2+ legs at 1/5 or bigger, boost from 3% on a double up to 200% on 20+ legs, maximum boost of £10,000 per online bet, running until 30 May 2027). The football customer has the most layered feature set on this list, and the welcome size sits second to that.

What the picture looks like to a customer who likes a spread-betting hybrid

Spreadex runs both fixed-odds and spread betting on the same account, with the FCA regulating the spread side and the Gambling Commission the fixed-odds side. The spread side can produce losses that exceed the deposit; that is the mechanism, and it is the reason spread betting is a different product from fixed-odds betting. Spreadex’s new-customer offer is £60 in free bets for a £10 fixed-odds bet, with the free bets usable across fixed odds and spread betting; the qualifying bet must be placed within 28 days of opening the account, and the qualifying fixed-odds bet must be at minimum odds of 1/2.

Spreadex fits a customer who already understands spread betting and wants a single account across both products. The £60 headline against a £10 fixed-odds qualifying bet is the largest on the list; the binding constraint is the 28-day window and the 1/2 minimum odds line, which is the lowest floor on the list.

What the 10x wagering cap means for the offers above

The 10x cap on bonuses in force since 19 January 2026 caps the turnover required to clear any bonus at ten times the bonus amount. A £10 bonus can require at most £100 of betting; a £50 bonus, at most £500; a £100 bonus, at most £1,000.

The cap bites hardest on the matched-deposit bonus shape. 10bet’s 100% up to £50 bonus, at 10x, requires £500 of turnover before withdrawal; a customer clearing that bonus pays the bookmaker’s margin on each of those bets, and the realised cost on a 5% margin market is about £25 of expected loss over the £500 of turnover (expected cost = required turnover × margin of the market). On a market with a 7% margin (typical of football 1X2), the expected cost is closer to £35.

The cap does not bite on a stake-back shape in the same way, because the customer receives the stake only if the qualifying bet loses and the free bet that follows is itself stake-not-returned. The realised cost of clearing a free bet is the bookmaker’s margin on the free bet itself, which lands in the same £1–2 band on a £10 free bet at modest odds.

The cap also does not bite on a matched-free-bet shape whose winnings are withdrawable on settlement, because there is no bonus to clear. The free-bet tokens at Coral, Unibet, Betway, BetGoodwin, Hollywoodbets, Betboro and Octobet sit in this last shape, and the cost of clearing them is the bookmaker’s margin on the free bet, not the bonus turnover.

Why the cap is a quieter win than it sounds

A 10x cap is a hard ceiling, and the £500 ceiling on a £50 bonus is a real constraint on the bonus shape. But it does not change the mechanism of a free bet: the stake-not-returned rule still applies, the minimum odds still apply, the expiry still applies. A customer who reads “10x cap” as “free bets are now generous” reads the rule wrong; the cap limits how heavy a bonus can be, and the small print on the free bet still does the rest.

The £-number free bet, on average

Take the standard case again: a £10 free bet at 3.0 on a two-way market with a 5% margin. The expected value is £10 × 2 ÷ 3 × 0.95, which works out to £6.33 of average value per £10 token. At 2.0 the value drops to £4.75; at 5.0 it climbs to £7.60. A £40 token spread across four bets, all at 3.0, lands around £25 of average value across the four tokens; the £40 headline is closer to £35–38 against the four bets at modest prices with a 5% margin.

Two things move the realised value up or down the band. Higher odds lift the average, up to a point; the maximum odds ceiling at QuinnBet is 50/1, and a token at the ceiling is closer to the token’s full face value. A long expiry widens the customer’s room to find a price worth taking. A market restriction that excludes accumulators narrows the room; a restriction that excludes singles narrows it further.

When a smaller headline is the better offer

A £15 headline at BetGoodwin, split across three tokens, looks small against the £40 headline at Coral. But a customer who uses all three tokens at prices above 2.0 captures roughly £13–14 of average value across the three, and a customer who uses only the £5 acca token at a higher price captures the same £13–14 on a smaller headline. A smaller headline with a wider market permission and a longer expiry can be the better offer for a customer with the right bet in mind.

A £40 headline at Coral with a 7-day expiry and a 2.0 minimum on the free bet is the right offer for a customer who already has a price at 2.0 in mind for the coming week. A £15 headline at BetGoodwin with three market permissions is the right offer for a customer who bets across the three and is happy with three tokens rather than one. A £60 headline at SBK with a 3.0 minimum on the qualifying bet is the right offer for a customer whose first bet is already at 3.0. The right offer is the one whose constraints fit the customer’s first bet, not the one whose headline is largest.

What happens after the welcome

A welcome offer is a token, not a relationship. The routine extras on top of it are the things a customer uses week-to-week: Best Odds Guaranteed, acca insurance, daily price boosts, free-to-play games, enhanced-odds specials, loyalty boosts. They sit across most of the brands on this list and are the second comparison to make once the welcome is spent.

Best Odds Guaranteed (BOG) pays out at the starting price if the starting price is bigger than the price taken, on horse racing. Swifty Sports and Unibet list it in their feature sets; the larger established brands run it as a matter of course. A customer who bets on racing routinely loses more to the absence of BOG than to the headline of a smaller welcome.

Acca insurance refunds the stake as a free bet (not cash) if one leg of an accumulator lets the bet down. BoyleSports lists acca insurance (opt-in, £5 minimum stake, 1/2 minimum odds, £20 maximum refund as a free bet expiring in 7 days) and an acca loyalty boost (opt-in, £5 minimum stake, 3/1 minimum combined odds, 5+ settled legs, free bet expiring in 7 days) in the App Store entry.

Daily price boosts and enhanced-odds specials sit at Coral, BetVictor, DAZN Bet, Unibet, William Hill (Football Acca Boost), bet365 (Bet Boosts, Super Boosts, Winnings Boosts on Bet Builders and selected singles) and others. The value of a daily price boost is the spread between the boosted price and the unboosted price; the spread varies by event and by brand, and the routine boost on a 2/1 shot is closer to a marketing token than to a value addition.

Free-to-play games sit at Coral (Football Super Series with a £10,000 jackpot) and several others. They are not bets in the Commission’s sense and are not subject to the wagering cap; they are also not a route to a withdrawal, and the prize structure is the operator’s own.

Loyalty and the routine free bet

Several brands run a routine free-bet programme beyond the welcome: Hollywoodbets lists daily free bets, 10bet lists daily free bets and free spins, Kwiff runs a Supercharge feature that can boost the odds on a bet from 2/1 to 20/1 in an instant, BoyleSports runs acca loyalty. The routine programme is what a settled customer sees week-to-week; the welcome is the front door.

A customer who intends to bet through the year, not the month, ranks the brands by the routine programme rather than by the welcome size. Coral’s Reward Shaker and daily Odds Booster, Unibet’s daily Uniboosts, bet365’s Super Boosts and William Hill’s Football Acca Boost are the layered routines on this list.

Pitfalls the small print hides

Three pitfalls the small print hides and the headline obscures:

The stake-not-returned rule. Stated once above, repeated here because it is the most-missed line in any free-bet terms. A free bet at 3.0 returns £20, not £30, on a £10 token. A customer who treats the headline price as the price takes 33% off the realised value.

The qualifying-bet minimum odds. Coral, Unibet and Betway set the qualifying line at 2.0; SBK sets it at 3.0; Betboro sets it at 1.60 on each leg of a three-leg minimum acca. A customer whose first bet was a 1.5 favourite does not qualify at Coral, Unibet, Betway or SBK, and a customer whose first bet was a single does not qualify at Betboro. The qualifying-bet minimum is the silent constraint.

The credit-card exclusion. Credit cards are banned for gambling in Great Britain since 14 April 2020, and the ban extends to credit-card-funded e-wallet top-ups. Several of the offers above explicitly require a debit card or instant bank transfer as the qualifying deposit method; a customer funding the deposit by credit card fails the test before the qualifying bet is placed.

Two less common pitfalls

The market restriction on the free bet. Several brands restrict the free bet to singles or each-way markets; others exclude virtual events; QuinnBet excludes Trixies, Patents and Yankees. A customer with a multiple in mind at Coral or Unibet has to redeploy onto a single.

The settlement window. Hollywoodbets’ stake-back is settled within 7 days; a customer whose first acca is voided or postponed past the window loses the offer even if the acca would have lost. The settlement window is the third clock alongside the qualifying-bet window and the free-bet expiry.

The verdict, by operator

Swifty Sports is the right pick for a customer who values Best Odds Guaranteed, live streaming and in-play betting over the size of a welcome token, and who is happy to skip the matched-free-bet headline for the routine racing package.

BetGoodwin is the right pick for a customer whose first bet is going to be a £10 across singles, accumulators and the Sub-Cover market, and who wants three tokens on different markets rather than one large token on a single market.

Betboro is the right pick for a customer whose first bet is already a three-leg acca at 1.60 per leg, and who wants a £25 free bet on top of a small first deposit.

Coral is the right pick for a customer who wants the £40 headline on a familiar name, can fund the qualifying deposit by debit card or instant bank transfer, and has a price at 2.0 in mind for the week.

Geoff Banks is the right pick for a customer whose interest is ante-post horse racing on a specialist bookmaker, and who is willing to set aside the matched-free-bet welcome.

Betway is the right pick for a customer who can fund the deposit by debit card, who is comfortable placing four £10 free bets rather than one £40 token, and who values the brand’s wider sportsbook catalogue.

Smarkets (SBK) is the right pick for a customer with a first bet at 3.0 already in mind, who wants the largest headline on the list and is interested in the exchange underneath the sportsbook.

Hollywoodbets is the right pick for a customer whose first bet is a small acca with three-plus legs at 4/1 or greater, and who is comfortable with the “win the cash or get the free bet on a loss” structure.

Octobet is the right pick for a customer who wants a stake-back on the sports side, is interested in the small casino layer, and has read the small print to confirm the two elements are not tied under the mixed-product rules.

10bet is the right pick for a customer who wants a matched-deposit bonus rather than a free bet, and who is comfortable with the £500 turnover ceiling at 10x to clear the bonus.

The numbers on a single page

A £20 deposit at Coral, Unibet, Betway or SBK qualifies the welcome at those brands. A £10 deposit qualifies at Betway, Betboro, BetGoodwin and Hollywoodbets. A £50 deposit clears the £50 ceiling on the 10bet matched-deposit bonus. A £25 deposit clears the £25 ceiling on the Betboro matched free bet. A £30 stake on a first losing acca at 4/1 or greater at Hollywoodbets captures the £30 stake-back ceiling. A £10 fixed-odds bet at 1/2 or higher at Spreadex qualifies the £60 free-bet headline within the 28-day window.

The qualifying stake ceiling and the free-bet ceiling are the two figures to set beside each other. A £40 token against a £20 qualifying stake at 2.0 is a 2:1 ratio; a £60 token against a £20 qualifying stake at 3.0 is a 3:1 ratio; a £25 token against a £10 qualifying acca at 1.60 per leg is a 2.5:1 ratio on a more restrictive shape; a £15 token against a £10 qualifying bet at BetGoodwin is a 1.5:1 ratio across three market permissions. The ratios are the figure a customer should set beside the headline, not the headline alone.

Frequently asked questions about free bet sign-up offers

How does a reader sign up at a betting site?

A reader signs up at a betting site by registering an account, completing the identity check (name, address and date of birth) before the first deposit, funding the account by a permitted method (debit card or instant bank transfer at most licensed brands; credit cards are banned for gambling in Great Britain), placing the qualifying bet at the offer’s minimum stake and minimum odds, and receiving the free bet on settlement. Each step runs inside the brand’s own terms; the licence is the test of whether the brand is permitted to take the bet at all.

How does a reader sign up at a sportsbook?

A reader signs up at a sportsbook the same way as at a betting site: register, verify, deposit, place the qualifying bet at the offer’s stated minimum stake and minimum odds, receive the free bet on settlement. The difference between “betting site” and “sportsbook” is branding rather than mechanism; both phrases cover fixed-odds betting on sport at a GB-licensed operator, and the same identity check, deposit method and qualifying-bet structure apply.

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

The maximum wagering requirement on a betting bonus in Great Britain is 10x the bonus amount, under the Commission’s promotion rules in force since 19 January 2026. A £10 bonus can require at most £100 of betting before any withdrawal; a £50 bonus, at most £500; a £100 bonus, at most £1,000. Whether the cap also applies to free bets with no wagering condition is not established by the regulator’s published guidance.

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

Minimum odds are the lowest price at which a bet qualifies for the offer (a qualifying line of 2.0 means only bets at decimal odds of 2.0 or higher count), and they apply to the qualifying bet, the free bet, or both. The wagering requirement is the number of times the bonus (or the bonus plus deposit) must be turned over in bets before any of it can be withdrawn; the 10x cap is the ceiling on that requirement in Great Britain.

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

The stake of a free bet is not paid back with the winnings because the free bet is a token issued by the operator rather than a cash stake placed by the customer; the operator pays the winnings (the profit) on a successful free bet, not the stake. A £10 free bet at decimal odds of 3.0 returns £20 of profit on a win, with the £10 stake retained by the operator; the headline price is therefore not the realised return.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

A bet on sport cannot be tied to a casino bonus under the Commission’s promotion rules in force since 19 January 2026, which ban mixed-product promotions — an offer that requires a customer to gamble on two or more product types such as betting, casino, bingo and lottery. A standalone sports free bet with a separate casino bonus offered alongside it (without a tying condition) is a different shape and is described in each operator’s own terms.
