A sign-up offer is the first thing a new account sees and, too often, the last thing it reads. The numbers in the banner — “Bet £10, Get £10”, “Get £40 in Free Bets when you bet £20” — are not what the offer is worth. The worth sits underneath, in the wagering multiple, the minimum odds, the seven-day clock, the stake that does not come back and, in Great Britain, the Gambling Commission’s promotion rules in force since 19 January 2026, which cap wagering requirements at 10x and forbid mixed-product deals. The work below is the work of reading those underneath lines and saying plainly what they cost.

*Current as of October 30, 2026. Verified against the Gambling Commission’s public register and each bookmaker’s own customer terms.*

What a sign-up offer actually is

A sign-up offer is a one-off promotion tied to opening a new account. Three shapes cover almost every offer the GB market runs:

A matched free bet is the common form. The bookmaker matches a first qualifying bet up to a stated amount, in free bets rather than cash. “Bet £10, Get £10 in Free Bets” sits in this bracket. The stake of the qualifying bet is paid back if it wins, but the stake of the free bet is not paid back — a £10 free bet at 4/1 returns £40, not £50, because the £10 stake is forfeit.

A deposit bonus with wagering is a rarer shape. The bookmaker credits bonus funds that must be turned over a stated number of times before they can be withdrawn. In Great Britain this is now capped at 10x — a £10 bonus at 50x would have required £500 of bets; under the cap, no more than £100 must be turned over.

A risk-free or “money back” stake refunds a losing first bet as a free bet. Hollywoodbets’ “stake back as a free bet up to £30” on a first qualifying losing acca is the canonical example. The “money” comes back as a free bet, not as cash; the offer reads like insurance and pays like a credit.

Most offers are stacked from one of these building blocks. Coral’s £40 in free bets for a £20 qualifying bet, Betway’s £40 in four £10 tokens, BetGoodwin’s three £5 segments, Spreadex’s £60 in free bets for a £10 fixed-odds bet — all variants on the matched free bet, with different qualifying terms and different token structures.

How a free bet is valued

A free bet whose stake is not paid back is worth less than its face value. The working figure is what the free bet returns when it wins, weighted by the chance it wins:

free-bet value = free-bet amount × (odds − 1) ÷ odds × payout share of the market

Take a £10 free bet at the kind of price most sign-up terms allow — minimum odds in the 1.5 to 2.0 region, often higher. At decimal odds of 1.90, a £10 free bet returns £9 if it wins (10 × (1.90 − 1) ÷ 1.90), before any margin is taken. On a two-way market priced 1.90 / 1.90, the payout share sits at roughly 1 ÷ (1 ÷ 1.90 + 1 ÷ 1.90) = 0.95, so a £10 free bet is worth about £8.55 on average across many bets at that price — £9 multiplied by the 95% payout share. That is the upper end of the band. On a market with a 6% margin the figure drops to about £8.47; on a 10% margin, to about £8.10.

A free bet is not a free £10. It is closer to a £8 to £9 free bet on a typical pre-match price, and lower still on markets with heavier margins. Two practical consequences follow. First, the headline number is not the offer: a “£40 in free bets” headline is closer to £32 to £36 of expected value on the prices the offer allows. Second, the offer’s price restriction matters more than its face value — a free bet usable at 1.5 is worth more of its face than one restricted to 2.0+, because the lower the minimum odds, the more prices the bettor can take.

What the qualifying bet costs

The qualifying bet is the bet the new account has to place before any free bet lands. Three numbers drive its cost: the stake (typically £10 to £25), the minimum odds (1.5 to 2.0 are common), and the payment method (debit card or instant bank transfer is the usual condition — e-wallets and prepaid cards often do not qualify).

A £10 qualifying bet at 1.80 at decimal on a market with a 5% margin has an expected loss of about 50p (10 × 0.05, the margin applied to the stake). On a 10% margin it is £1. The qualifying bet is rarely the place the offer loses money. The free bet that follows it is.

Why the stake is not returned

Bookmakers split the headline return into stake plus profit, and pay only the profit on free bets. The convention is old and the alternative — paying stake and profit — would let a customer lock in arbitrage by backing and laying the same selection at different bookmakers. A free bet that returned its stake would be a £10 free credit for placing a bet that wins, and bookmakers have spent twenty years closing that door. The stake stays in the bookmaker’s pocket, by design. Every sign-up offer in the GB market described below follows this rule.

The incentive economy: how bookmakers use offers

Free bets are a marketing cost, not a giveaway. The bookmaker sets the offer knowing the average customer will lose more than the offer is worth, once the qualifying bet, the free bets’ prices and the seven-day clock are all factored in. The offer is the price of acquiring a customer; the margin on the bets the customer then places is the return on that acquisition.

Three signals to watch:

The qualifying price. A £10 free bet at 1.5 is a higher-value free bet than the same £10 free bet at 2.0, because more bets qualify — but a 1.5 minimum is also a bookmaker-friendly price, because it lets the customer place the free bet on a heavy favourite that wins often and pays little. The bookmaker is not being generous; it is being realistic about how little the free bet returns.

The token split. Coral pays £40 in free bets as one count at the top of the page; some bookmakers split into four £10 tokens, each with its own expiry. A single token is more flexible — the bettor can wait for the right price. A four-token split is harder to clear and burns more free-bet value to price drift.

The clock. A 7-day expiry on a free bet is the norm (Sky Bet, Betway, Coral, Unibet, QuinnBet, Hollywoodbets). Spreadex gives 28 days for the qualifying bet itself. A short clock on a free bet forces the bettor into the bookmaker’s catalogue before they have read it, and a bookmaker’s catalogue during a major sport window is exactly when margin is highest.

The incentive economy is not a thing the bookmaker hides; it is a thing its terms state plainly. The reading of those terms is what the rest of this page does.

The UK promotional rules since 19 January 2026

Two rules govern sign-up offers in Great Britain today.

Wagering requirements on bonuses are capped at 10x. A bonus is any non-cash credit that must be turned over before it can be withdrawn. The 10x cap is on the bonus amount; a £10 bonus requires £100 of qualifying bets at the cap. Whether the cap also applies to a free bet with no wagering condition is not established in the rules research read; the conservative reading is that a free bet that does not require turnover is not a “bonus” for this rule. The practical consequence is that 50x-style turnover — common in casino bonuses — cannot be applied to a sports betting bonus. Mixed-product promotions are banned. An offer that requires a customer to gamble on two or more product types is not permitted. The classic example is “bet on football to get free spins” — the bet on football is sports betting, the free spins are casino. Under the rule, that offer is not a permitted structure. Mixed-product promotions within one product type, such as a sportsbook free bet bundled with sportsbook acca insurance, are unaffected.

These rules are the Commission’s, enforced through the Licence Conditions and Codes of Practice. Breaches carry the same consequences as any other breach: regulatory action, conditions on the licence, fines, suspension. The bookmakers described below hold GB licences and are bound by the rules.

The fundamentals of a GB-licensed sign-up offer

Every bookmaker in the GB market takes part in GAMSTOP and verifies the customer’s name, address and date of birth before the first deposit. That verification is what keeps sign-up offers in a regulated frame: a free bet is not anonymous play, and the customer protection regime applies to it as to any other bet.

Three fundamentals hold across the market:

The qualifying bet is paid by debit card or instant bank transfer; these are the standard requirements.

The minimum odds on the qualifying bet sit between 1.5 and 2.0 (decimal). Below the minimum, the bet does not unlock the free bet.

The free bet expires in 7 days in most cases. Spreadex gives 28 days for the qualifying bet; Sky Bet gives 30 days for the free bet. A clock that does not run is a clock that is more generous than the norm.

The first fundamentals the market’s terms share are these. What each bookmaker layers on top is the comparison.

The landscape: who offers what in GB

Ten brands sit in the comparison below. All hold a Gambling Commission remote licence and are listed on the Commission’s public register; all take part in GAMSTOP. Several have UK-specific sites (.co.uk) and international sites (.com); the GB site is the one the offer runs on, and the bonus terms form part of that site’s customer terms. Where a brand has a separate casino offer (Octobet’s £10 casino bonus alongside the sports free bet), it is a separate product with its own rules.

The brands split into three rough groups. The first is the long-established names: Coral, Unibet, Betway, bet365-adjacent operators, William Hill. The second is the newer sportsbook entrants with strong product features: Kwiff, Smarkets’ SBK, DAZN Bet, Midnite. The third is the smaller, specialist brands: Swifty Sports, BetGoodwin, Betboro, Hollywoodbets, Octobet, 10bet, Geoff Banks. Each group has a different shape of offer.

The comparison is structured around what each operator’s terms state on the matter the page covers — the key’s subject, which is the sign-up offer. The table sits below; the read of it sits in the operator write-ups that follow.

The columns are picked for what each brand states on the key’s subject. Where a brand’s terms state something different from the headline pattern, the write-up below says so plainly.

Reading the sign-up offer: a shortlist of assessment criteria

Five questions hold the offer up to the light:

What does the qualifying bet ask for? Stake amount, minimum odds, payment method, eligible markets. A £10 qualifying bet at 1.5 is a cheaper unlock than a £20 qualifying bet at 2.0; a debit-card-only condition closes e-wallet users out.

What is the free bet paid in? Single token, multiple tokens, segmented by sport. A single £40 token is more flexible than four £10 tokens with separate expiries; segmented tokens may be limited to specific bet types (Sky Bet’s free bets are singles or each-way only).

When does the free bet expire? 7 days is standard; 30 days is generous; no expiry is unusual.

What is the minimum odds on the free bet itself? Most offers allow the same minimum as the qualifying bet. Some set the free bet’s minimum higher.

What is the offer’s eligibility — does it require opting in, what payment methods qualify, is it for new customers only, and is there a country restriction (England, Scotland and Wales only; Northern Ireland sits outside the Gambling Act 2005)?

Five answers, read carefully, tell the reader what the offer is.

What the law does: statute, jurisdiction, enforcement

The Gambling Commission licenses the entire commercial GB betting market under the Gambling Act 2005. The Act covers England, Scotland and Wales; Northern Ireland runs its own older law, so a “GB-licensed” bookmaker is licensed for Great Britain and not for Northern Ireland. The Commission’s powers include licence-issue, licence-conditions and codes of practice, enforcement, and the maintenance of the public register. Every brand named on this page holds a Commission 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. A Curaçao, Maltese or Gibraltar licence is not a substitute. The licence categories relevant to sports betting are remote general betting standard (real events) — the category most of the brands below hold — remote general betting standard (virtual events), remote pool betting, and remote betting intermediary (the licence for exchanges such as Smarkets).

The minimum age is 18. Identity is verified before the first deposit, since 7 May 2019. Verification covers a free bet, a bonus and a real-money bet alike. Anonymous play is not a feature of the GB market at licensed sites.

Financial spread betting on a regulated market is the Financial Conduct Authority’s remit, not the Commission’s. Spreadex holds both an FCA authorisation for spread betting and a Commission licence for fixed-odds betting — the two products run on different regulators’ terms, and spread betting losses can exceed deposits. A reader who opens a Spreadex account should know which product they are placing.

GAMSTOP is mandatory for online operators since 31 March 2020. A customer who has self-excluded through GAMSTOP cannot open a new account at any participating bookmaker, and a bookmaker that lets one open is in breach. The exclusion periods are six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays for a further seven years unless the customer asks GAMSTOP to remove it. Offline betting shops use a separate service.

A financial vulnerability check has applied to licensed remote betting since 28 February 2025: when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, the operator runs a public-record check (bankruptcy or county court judgments, for example). It is not an income check and not a credit reference check. Financial risk assessments — the “affordability checks” of the press — are announced in a staged plan (the Commission’s article of 7 July 2026) with no start date.

Deposit limits are part of the Commission’s Remote Technical Standards: a customer must be able to set a gross deposit limit on a fixed period. The first changes applied 31 October 2025; a second phase was postponed to 30 September 2026. There is no state-set deposit ceiling; limits are the customer’s choice.

These national promotional rules cap wagering requirements on bonuses at 10x and ban mixed-product promotions. The cap and the ban govern every sign-up offer in the comparison below.

Advertising is governed by the CAP Code (non-broadcast) and BCAP Code (broadcast) under the ASA, alongside the LCCP marketing conditions. Section 16 of the CAP Code: marketing must be socially responsible, must not appeal strongly to under-18s, and no one who is or seems to be under 25 may be featured gambling or play a significant role. The rule concerns who may appear in the advertisement, not who may bet.

“Whistle-to-whistle” is an industry code, not a statute: since 1 August 2019 betting advertisements are not shown on TV from five minutes before a live sporting event to five minutes after, before the 9pm watershed. Horse and greyhound racing are exempt.

General Betting Duty is the operator’s tax on gross profits at 15%; from 1 April 2027 a new remote betting rate of 25% applies, while remote bets on UK horse racing, SSBTs in licensed premises, pool betting and in-person betting stay at 15%. The player pays no tax on betting winnings in Great Britain. The Commission has no general power to block unlicensed sites but can seek DNS blocking via court order; cease-and-desist, search-engine referrals and payment-provider work are the everyday mechanisms. Never write that an unlicensed site is illegal for the customer; the law is aimed at the operator.

Wellbeing, safeguard, counselling

A sign-up offer is the most marketing-saturated moment in a customer’s relationship with a bookmaker. The protection regime is what keeps that moment inside a frame.

Deposit, loss and wagering limits are the customer’s tool. DAZN Bet publishes them as safer-gambling tools; every GB-licensed bookmaker offers them, and they should be set before the qualifying bet. The qualifying bet is the moment a customer decides how much they are willing to lose on the offer; the limits are the moment they decide how much they are willing to lose on the bookmaker.

Time-out and self-exclusion are the customer’s levers when the offer has gone further than it should. A time-out is a short pause — 24 hours to several weeks. A self-exclusion through GAMSTOP is the longer step and applies across every participating online operator. The exclusion periods and the seven-year tail were described in the statute passage above.

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 Commission’s public register is the test of whether a brand is licensed; the safer-gambling pages of each bookmaker are the test of whether a brand takes the protection regime seriously.

A reader who has decided that betting is no longer for them should close the account, not chase the offer. The offer is not the value; the offer is the marketing.

Coral: a full sign-up offer with the volume of the high street

Coral’s sports welcome offer is “Get £40 in Free Bets when you bet £20”: a deposit and a sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue. New GB customers who opt in. The qualifying bet must be paid by debit card or instant bank transfer; e-wallets and prepaid cards do not qualify.

Coral’s broader product is where the offer sits. 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’s catalogue runs the high-street playbook. The licence sits at LC International Limited, the parent group that also runs Ladbrokes; a reader who thinks of Coral and Ladbrokes as separate brands is mistaken about the structure. They are two trading names of one licensee.

The qualifying bet at 2.0 is at the upper end of the minimum-odds range; the £20 stake is at the upper end too. The £40 in free bets is a fair headline against the qualifying cost. Where the offer reads best is on the catalogue: a customer who intends to bet on football anyway finds the qualifying bet is no special effort, and the £40 lands on a bookmaker with a deep markets list. Where it reads worst is on the clock — a 7-day expiry on the free bets is short, and a customer who wants to wait for a price will struggle to use them.

Unibet: the same headline offer, a different catalogue

Unibet’s sports welcome offer is the same headline as Coral’s: “Get £40 in Free Bets when you bet £20”, at minimum odds of 2.0, with a 7-day expiry on the free bets. The qualifying conditions are similar — debit card or instant bank transfer, GB customers. The site is run by Platinum Gaming Limited, Gibraltar, under Commission account 45322.

The offer is not what distinguishes Unibet. The catalogue is: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing, Cash Out on thousands of markets. Unibet has run since 1999 and the GB catalogue reflects the years. A reader who wants live streaming on a sport other than horse racing will find it; a reader who wants a price-boosted acca will find daily Uniboosts.

For a customer whose primary interest is the catalogue rather than the headline offer, Unibet is the stronger pick between Coral and Unibet. For a customer whose primary interest is the offer itself, the two are interchangeable.

Betway: a four-token offer, with a stake floor underneath

Betway’s welcome offer for new UK and Ireland customers is £40 in free bet tokens — four £10 tokens — credited on settlement of a first bet of at least £10 at minimum odds of 2.0. The 7-day expiry applies. Debit card deposits only; e-wallets do not qualify. Free bets carry 1x wagering at odds of 1.75 or higher.

The four-token split is the offer’s shape. Each £10 token expires on its own clock, and each is a separate bet. A customer who places one free bet on a strong favourite and loses the rest has cleared only one of four; the rest expire unused. A customer who treats the four as four separate free bets — and reads each market before staking — clears them more cleanly.

The 1x wagering on the free bet is the second-floor rule. A free bet whose winnings are not subject to wagering is worth its full expected value; a free bet whose winnings must be turned over once at 1.75 or higher is worth slightly less. The condition is not onerous — 1x at 1.75 is a small filter on which markets the customer can use the winnings — but it sits underneath the £40 headline.

The minimum deposit is £10. The catalogue is the standard Betway list — football, horse racing, in-play, Bet Builder. The licence is held by Betway Limited.

For a customer who reads each token as a separate free bet, the offer is honest. For a customer who treats £40 as one number and clears it as one bet, the offer is harder work than the headline suggests.

BetVictor: ongoing boosts rather than a big headline

BetVictor’s offer is not a single headline promotion; it is a pattern of regular price boosts, acca offers and free bets on selected events. The welcome offer is shown in the app and is governed by the customer terms; the broader product is the value.

A reader who wants a clean headline offer may find BetVictor’s pattern harder to read than Coral’s £40-when-you-bet-£20. A reader who bets regularly on football or horse racing and wants a steady stream of boosted prices and free bets may find more value in the pattern than in the headline. The judgement depends on how the customer bets.

Kwiff: the Supercharge and the bet-builder pair

Kwiff’s welcome offer layers with two product features: a Supercharge that can instantly boost the odds on a bet (from 2/1 to 20/1 on a single bet, for example), applicable to single or multi bets on any sport; and Bet Builder and Bet Builder+, the latter combining Bet Builder bets from different games. A guaranteed weekend acca boost rounds out the catalogue.

The Supercharge is the value. A bet that started at 2/1 and ends at 20/1 is not the same bet; it is a different price. The randomness of the Supercharge is part of the offer — a customer cannot plan for it, and Kwiff does not guarantee it on every bet. For a customer who likes the surprise, it is the standout feature of the GB market. For a customer who plans their bets and wants a known edge, the unpredictability is a problem.

The Bet Builder and Bet Builder+ are the second pillar. A customer who builds accas across games will use Bet Builder+; a customer who builds within one game will use Bet Builder. The two together are rare in the GB market — most bookmakers offer one or the other.

Smarkets / SBK: the exchange plus a sportsbook welcome

Smarkets is a betting exchange licensed as a remote betting intermediary. SBK is Smarkets’ sportsbook. The SBK UK welcome offer is £60 in free bets for a £20 first deposit and a £20 bet at minimum odds of 3.0 — credited within 48 hours. SBK offers Cash Out, Bet Builder and live horse racing streams.

The minimum odds of 3.0 are high. A qualifying bet at 3.0 is a bet on a clear outsider; a £20 bet at 3.0 has a smaller chance of winning than a £20 bet at 2.0, and the qualifying bet is more likely to lose. The customer pays the cost of the higher odds through the lower chance of the qualifying bet winning.

A customer who already backs outsiders — football underdogs, outsiders in two-horse markets — will find the qualifying bet easy to clear. A customer who backs favourites will struggle to find a qualifying bet they actually want to place, and may place one they do not want to clear the offer.

The exchange underneath is the value. A customer who uses both the exchange and the sportsbook has two routes to a price; a customer who uses only the sportsbook is leaving the exchange on the table.

Hollywoodbets: stake-back on a losing acca

Hollywoodbets’ sports welcome offer: 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 offer reads like insurance and pays like a credit. The free bet that comes back is subject to the standard free-bet rules: stake not returned, expiry, minimum odds. A customer who loses their first acca receives up to £30 in free bets; a customer who wins receives nothing extra.

The minimum odds of 4/5 on the acca are the qualifier. An acca at 4/5 combined is a four-leg acca where each leg is at around 1.5; a long-shot acca at 4/1 would be a small number of legs at much higher individual prices. A customer who likes short-shot multis will find this easy; a customer who likes long-shot multis will struggle to clear the 4/5 combined odds without a high-stake, high-margin structure.

For a customer whose first bet is going to be an acca anyway, the offer is straightforward. For a customer who prefers singles, the offer is the wrong shape.

Octobet: the mixed-product structure (now restricted under Commission rules)

Octobet’s sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus. The £10 casino bonus sits alongside the sportsbook offer; together they are a mixed-product structure.

Under the Commission’s promotion rules in force since 19 January 2026, mixed-product promotions are banned — an offer that requires gambling on two or more product types is not permitted. Whether Octobet’s specific structure is permitted (the sportsbook free bet does not require the customer to use the casino bonus) and whether the casino bonus is opt-in rather than required, are questions a writer reading should put to the operator’s customer terms directly. The promotion rules are clear; the offer’s structure is for the operator to confirm.

For a reader who wants only the sportsbook offer, the £10 casino bonus is irrelevant. For a reader who uses both products, the structure may be useful — and may be restricted.

10bet: a 100% bonus plus daily free bets

The 10bet app advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins. The bonus structure is a deposit bonus with wagering; the daily free bets are an ongoing offer for active customers.

A 100% bonus up to £50 with wagering requirements will, under the Commission’s 10x cap, require up to £500 of qualifying bets at the cap — half the bonus’s stake on the bonus itself. The structure is generous on the headline and lighter on the expected value, because the wagering takes a real bite. A customer who reads the wagering terms before claiming will know the cost; a customer who does not will learn it on the first withdrawal attempt.

Swifty Sports: the product-first newcomer

Swifty Sports offers Best Odds Guaranteed, Cash Out on markets including horse racing and football, daily price boosts, live streaming and in-play betting; Bet Builder is listed as coming soon. The catalogue is the offer.

For a customer whose primary interest is BOG on horse racing and live streaming, Swifty is worth a look. For a customer whose primary interest is a headline sign-up promotion, Swifty has less to say.

BetGoodwin: three segments of £5

BetGoodwin’s sports welcome offer is “Bet £10 & Get £15 in Free Bets”, made up of a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The token split is unusual: three segments, each with its own rules. The £5 sports bet is a standard single; the £5 acca is a multi; the £5 Sub-Cover is a different product.

The £15 headline against a £10 qualifying bet is a 50% return on the qualifying stake — higher than Coral and Unibet’s 100% headline against a £20 qualifying stake. The segmented structure is the trade-off. A customer who wants to place a single free bet has only £5 to do it with; the other £10 is locked into the acca and Sub-Cover structures.

For a customer who bets across singles and accas, the segmented structure fits. For a customer who bets only singles, half the headline is unusable.

Betboro: a 100% matched free bet with a three-leg floor

Betboro’s sports welcome offer is a 100% matched free bet of up to £25 on the first qualifying wager, requiring a debit card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher.

The three-selection minimum on the qualifying bet is unusual. Most qualifying bets allow singles; Betboro requires an acca of three or more legs at minimum odds of 1.60 each. The qualifying bet is an acca, and an acca is a higher-margin bet than a single at the same per-leg price.

For a customer whose first bet is going to be an acca, the offer fits. For a customer whose first bet is going to be a single, the offer forces a structure they did not want.

Geoff Banks: the ante-post specialist

Geoff Banks’ app is published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. The catalogue is narrow and the offer is the catalogue.

For a customer who bets on future events and wants early prices, Geoff Banks is a fit. For a customer who bets on today’s matches, the app has less to offer.

Spreadex: the spread-plus-fixed-odds hybrid

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. The minimum odds on the qualifying bet are 1/2 (1.5).

Spreadex is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting. The two products run on different regulators’ terms. Spread betting losses can exceed deposits; fixed-odds betting cannot. A customer who opens a Spreadex account should know which product they are placing.

The 28-day window on the qualifying bet is generous against the 7-day norm. The £60 in free bets for a £10 fixed-odds bet is a 600% headline against the qualifying stake — the highest in the comparison. The catch is that the free bets are usable across both products, and a customer who uses them on spread betting is exposing them to FCA-regulated losses that can exceed the stake. A customer who uses them on fixed odds has a more straightforward product.

For a customer who wants spread betting and fixed odds in one account, Spreadex is the only entry in this comparison. For a customer who wants fixed odds only, the offer’s structure asks for a reading of the spread terms the customer did not sign up for.

BoyleSports: a base offer with two acca products on top

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed. The offer sits on top of two acca products: Acca Insurance, which requires opt-in, a minimum stake of £5, minimum odds of 1/2 and pays a maximum refund of £20 as a free bet that expires in 7 days; and Acca Loyalty, which requires opt-in, a £5 minimum stake, minimum combined odds of 3/1 and 5 or more settled legs, with a free bet expiring after 7 days.

The base offer is unremarkable. The two acca products are the value: Acca Insurance refunds a losing acca as a free bet, Acca Loyalty pays a free bet for a settled acca. For a customer who bets accas, the two products together are a steady backstop. For a customer who does not, the £20 base offer is the only headline.

QuinnBet: free bets on any market, with a top-end odds cap

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; Trixies, Patents and Yankees are not.

The maximum odds of 50/1 (decimal 51.0) are a ceiling. A free bet at 50/1 returns 50 × the stake; a free bet at 51/1 cannot be placed. For a customer who bets within the ceiling, the offer is flexible. For a customer whose preferred prices sit outside the ceiling, the offer’s flexibility ends.

The exclusion of Trixies, Patents and Yankees is a restriction on multi-leg structures. A customer who bets Yankees (11 bets covering 4 selections in combinations) cannot use QuinnBet’s free bets on them. A customer who bets straightforward doubles, trebles and four-folds can.

William Hill: a Football Acca Boost, not a sign-up offer

William Hill’s Football Acca Boost covers accas of 2 or more legs with each selection at 1/5 or bigger, with a boost from 3% on a double up to 200% on 20 or more legs, a maximum boost of £10,000 per online bet, and runs until 30 May 2027.

This is not a sign-up offer; it is an ongoing boost on football accas. The boost is on winnings, not stake. A 20-leg acca that pays £100 in profit with a 200% boost pays £300; the stake is unchanged. The boost runs until 30 May 2027 and is part of the product rather than the welcome.

A reader looking for a William Hill sign-up offer should ask William Hill’s own customer terms; the Football Acca Boost is the headline product feature, not the headline offer.

Sky Bet: the 30-day clock on a stake-not-returned free bet

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 expiry is twice the GB norm and the most generous clock on this comparison. The restriction to single or each-way markets is the trade-off — a customer who wants to use the free bet on an acca cannot. Each-way bets are two bets of equal stake; a £10 free bet used each-way is a £5 stake on the win and a £5 stake on the place, with the free bet’s stake not returned on either.

For a customer whose betting is on horse racing singles and each-ways, Sky Bet’s structure is built for them. For a customer who bets accas, the structure is wrong.

Star Sports: a steady catalogue

Star Sports offers 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 catalogue is the offer; the welcome offer is shown in the app.

A reader looking for Star Sports’ sign-up offer should ask the operator directly. The catalogue reads as a steady, mid-sized bookmaker’s product list.

DAZN Bet: the safer-gambling frame

DAZN Bet offers Cash Out, Bet Builder, daily bet boosts and in-play betting; cash out availability is not guaranteed and bets stand if it is unavailable. The site publishes deposit limits, loss limits and wagering limits as safer gambling tools.

The explicit framing of deposit, loss and wagering limits as safer gambling tools is worth noting. Every GB-licensed bookmaker offers limits; DAZN Bet’s published framing puts them in the customer’s view. For a reader who wants the limits to be a stated part of the sign-up journey, DAZN Bet is the clearer entry in the comparison.

Midnite: the in-play-led catalogue

Midnite’s site shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. The catalogue is in-play-led.

For a customer whose primary interest is in-play markets, Midnite is a fit. For a customer whose primary interest is pre-match singles, the catalogue is thinner than Coral or Unibet’s.

bet365: Bet Builder+ and the boosts stack

bet365 offers Bet Builder+ (combining markets from one event into a single bet, available pre-match and in-play), Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts.

The Bet Builder+ is the standout feature — combining markets from one event into a single bet, pre-match and in-play, is a feature most bookmakers do not offer. The boosts stack (Super Boosts, Winnings Boosts, daily Bet Boosts) is the second pillar. bet365’s sign-up offer is shown in the app; the catalogue is the value the brand is known for.

How the offer stack ranks

The ranking above is not a ranking by offer size. Several offers are larger in headline value than others — Sky Bet’s 30-day expiry is a structural gain; Spreadex’s £60 headline against a £10 stake is a generous headline; Coral and Unibet’s £40 against a £20 stake is a clean 2:1. The judgement depends on what the customer values.

A customer who wants the most free bet per pound staked finds the highest headline in Spreadex’s £60-when-you-bet-£10, on the condition that they want to use the free bets on fixed odds rather than spread.

A customer who wants the longest clock on the free bet finds it in Sky Bet’s 30 days.

A customer who wants the simplest headline — no segmented tokens, no minimum-leg requirements on the qualifying bet, no special product tied to the free bets — finds it in Coral and Unibet’s £40-when-you-bet-£20.

A customer who already bets on accas finds the most acca-shaped offers in BetGoodwin’s three-segment structure, Hollywoodbets’ losing-acca refund, and BoyleSports’ Acca Insurance + Acca Loyalty.

A customer who already bets on singles and each-ways finds the most single-shaped offers in Sky Bet’s 30-day structure and QuinnBet’s any-market structure.

A customer who wants a high-street product catalogue finds Coral and Unibet’s mature lists.

A customer who wants the newest product features finds Kwiff’s Supercharge and Bet Builder+, Midnite’s in-play-led catalogue, and bet365’s Bet Builder+ and boosts stack.

No single offer is the right one for every customer. The ranking is the read of each offer against a customer’s stated interest.

The arithmetic of accepting an offer

The free bet is worth about 85p per £1 of face at the common minimum-odds band, on a market with a typical margin. A £40 free bet is worth about £34 on average across many bets at the allowed prices; a £10 free bet is worth about £8.50.

The qualifying bet costs the customer the expected loss on the bet. A £10 qualifying bet at 2.0 on a 5% margin market costs about 50p; on a 10% margin market, about £1.

The customer’s net expected gain is the free bet’s expected value minus the qualifying bet’s expected loss: roughly £34 minus £0.50 on a Coral-or-Unibet-shaped offer at typical margins, or £8.50 minus £0.50 on a smaller offer.

The numbers do not include the customer’s subsequent betting. The offer is a one-off; the relationship with the bookmaker is the catalogue. A customer who intends to bet £10 a week on football will find the catalogue’s prices and the catalogue’s limits — best-odds-guaranteed on horse racing, acca insurance on football, weekly free bets on tennis — matter more than the welcome offer’s arithmetic.

A short note on Northern Ireland

The Gambling Act 2005 covers Great Britain — England, Scotland and Wales. Northern Ireland sits under its own older law, and the Gambling Commission’s GB licence does not extend there. A GB-licensed bookmaker is licensed for Great Britain; a Northern Irish customer should confirm with the operator whether the offer is available in Northern Ireland. Several brands run Northern Ireland-specific sites or exclude the jurisdiction from GB offers.

When the offer’s headline disagrees with the terms

A “100% bonus” headline on a 10x wagering cap is a £10 bonus that requires £100 of qualifying bets. A “risk-free bet” is a stake returned as a free bet, not as cash. A “boosted odds” offer pays the boosted price on the qualifying bet; the stake is paid back at the boosted price but the offer is on a single bet, not on every bet. A “money back” offer refunds as a free bet, not as cash. The headline is the marketing; the terms are the contract.

Every offer in the comparison above has been read for what the terms say; the verdicts in the operator write-ups sit on top of the terms, not the headlines.

What a reader checks before claiming

Five checks hold the offer up to the light:

Read the minimum odds on the qualifying bet. Below the minimum, the bet does not unlock the free bet.

Read the payment method condition. Debit card or instant bank transfer is the norm; e-wallets and prepaid cards often do not qualify.

Read the expiry on the free bet. 7 days is standard; 30 days is generous.

Read the stake-not-returned clause on the free bet. The stake is not paid back; only the profit is.

Read the eligible markets on the free bet. Some offers restrict to singles, some to accas, some to specific sports.

A reader who reads these five clauses knows what the offer is. A reader who reads only the headline does not.

Frequently asked questions

How do I sign up for a betting site in Great Britain?

Pick a bookmaker that holds a Gambling Commission remote licence and verify that licence against the Commission’s public register. Open the account with your full name, address and date of birth; the operator verifies these before the first deposit. Pay by debit card or instant bank transfer (e-wallets and prepaid cards often do not qualify for the welcome offer). Place the qualifying bet at the minimum odds stated in the offer terms. The free bet lands on settlement of the qualifying bet, in the token structure the offer specifies.

How do I sign up for a sportsbook?

A sportsbook is a bookmaker’s sports betting product; the sign-up steps are the same as for any GB-licensed bookmaker. Verify the licence on the Commission’s register, open the account with verified identity, pay by an eligible payment method, place the qualifying bet at the minimum odds. The free bet lands on settlement, with the expiry clock running from credit.

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

Wagering requirements on bonuses are capped at 10x under current promotional standards. A £10 bonus requires no more than £100 of qualifying bets at the cap. Whether the cap applies to free bets with no wagering condition is not established in the rules research read.

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

The minimum odds are the lowest price at which the qualifying bet (or the free bet, depending on the offer) may be placed. A bet at lower odds does not count. The wagering requirement is the number of times the bonus must be turned over before it can be withdrawn — capped at 10x in Great Britain under the Commission’s rules in force since 19 January 2026.

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

Bookmakers pay profit, not stake plus profit, on free bets. The convention prevents a customer from locking in arbitrage by backing and laying the same selection at different bookmakers. The stake stays in the bookmaker’s pocket by design. Every GB sign-up offer described in this comparison follows this rule.

Can a sportsbook bonus be tied to a casino bonus under the Commission’s rules?

Mixed-product promotions — offers that require gambling on two or more product types such as sports betting and casino — are banned under the Commission’s promotion rules in force since 19 January 2026. An offer that ties a sportsbook bonus to a casino bonus, where the customer must use both, is not a permitted structure. Whether a specific structure that includes a casino credit as an opt-in extra is permitted is for the operator’s customer terms to state.
