The phrase “bookmaker promo codes” suggests a secret key that unlocks something the next customer down the queue will not get. That picture is wrong, and the gap between the picture and the reality is where most of the cost in a “free” betting offer sits. What gets handed over at sign-up is rarely a discount on the act of betting; it is a small bundle of bonus money or free bets that carries rules about how many times it must be staked, at what price, and within what window. The value of the bundle is the arithmetic those rules produce — and that arithmetic, not the headline number, is the figure a punter should be reading.

This page is written for someone weighing a sign-up offer, weighing an existing-customer free bet, or comparing two welcome packages side by side. It is built around the rule change that took effect on 19 January 2026, when the Gambling Commission’s new promotion rules capped wagering requirements at 10x and banned offers that mix product types. Every welcome offer described below has to live inside that frame. Outside it, the same word — “free bet” — can carry very different weight.

The data below is current as of 27 October 2026 and was checked against the Gambling Commission’s public register of remote operating licences.

The Shape of a Betting Offer in Great Britain

A welcome offer from a GB-licensed bookmaker is one of three things, and they look different on a betting slip once the marketing layer comes off.

The first is a matched free bet. A deposit of £10, £20 or more is required, and a qualifying bet at a stated minimum price triggers a free bet of typically £20 to £60. The free bet is credited as a token; if it wins, only the winnings come back, not the token itself. The qualifying bet is paid back to the customer in full — that part of the deal is a real bet, settled at the price taken — but the free bet that depends on it is stake-not-returned.

The second is a stake-back on a losing first bet. A small qualifying stake — £10 is common — gets returned as a free bet of up to a stated ceiling if it loses. The ceiling matters because a £10 losing stake on a 20/1 shot is worth £10 in free-bet credit, while the same stake on an evens shot is also worth £10 in credit; the difference between the two outcomes is invisible to anyone reading only the headline. The free bet, again, is stake-not-returned.

The third is a deposit bonus. A percentage of the deposit — 50%, 100% — is added as bonus money, subject to a wagering requirement. This is where the 19 January 2026 cap bites hardest: under the old rules a 100% bonus at 50x wagering could ask for £500 of betting on a £10 bonus; under the new rules no bonus in Great Britain may require more than 10x that bonus in stakes before withdrawal.

These three shapes do not exhaust the catalogue. Some operators layer the welcome on top of an existing-customer offer — a “Bet £10, Get £30” followed by acca boosts and odds boosters that run week to week. Those ongoing promotions carry their own terms and usually have lighter wagering conditions than the headline offer, but they also tend to expire quickly and to apply only to specific markets.

The 10x Wagering Cap and What It Does

The Gambling Commission’s promotion rules, in force since 19 January 2026, set two hard limits.

First, wagering requirements on bonuses are capped at 10x. A bonus of £10 may not require more than £100 of betting before it converts to withdrawable cash. The cap is on the wagering multiple, not on the bonus amount itself, so a 100%-up-to-£50 bonus carries a maximum of £500 of required turnover at the new cap, against a possible £2,500 under the older 50x norm. The rule is the same for free-bet credit as for bonus money, with one open question: whether a free bet that carries no wagering condition at all — the £40-credited-as-four-tokens model used by Sky Bet and others — is itself caught by the cap. The Commission’s published guidance is silent on the point, and operators’ own terms are the only source to read.

Second, mixed-product promotions are banned. Any offer that asks the customer to bet on sport in order to unlock casino free spins, bingo credit or lottery entries is now prohibited. The rule is about the structure of the offer, not about the size of the prize: a free bet that is contingent on a casino deposit is out, while a free bet that is contingent on a sports bet at a minimum price is in.

The cap has not made every offer good. It has changed the distribution: bonuses of modest size and modest wagering requirements are now the bulk of the market, and the punitive 50x bonuses that used to populate the welcome page have largely retreated. The cap is silent on minimum odds, on expiry windows, and on whether the stake of a free bet is returned with the winnings — all of which are still set by each operator’s own terms.

Identity Checks, Deposits and the First Bet

Every operator in this comparison verifies identity before the first deposit. Since 7 May 2019 name, address and date of birth have been checked at the point of registration, with the check covering free bets and bonus credit as well as real-money stakes. The practical effect is that no licensed GB site offers anonymous play, and the marketing of “no verification” — common on offshore brands — is the first signal that a site is operating outside the British regime.

Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet deposits. A welcome offer that names “debit card or instant bank transfer” as the qualifying payment is reflecting the rule. Where the welcome offer is silent on payment method, the rule still applies — a customer who deposits by credit card cannot unlock the offer, and the offer terms will say so in the small print.

Beyond the deposit, a financial vulnerability check applies when deposits minus withdrawals cross £150 in a rolling 30-day window. The check is a public-record check — bankruptcy registers, county court judgments — not an income or credit reference check. It is the light-touch end of the affordability regime that the Commission has been building since 2024. A staged set of financial risk assessments (the heavier “affordability checks” of the press) was announced in a Commission article of 7 July 2026, with no start date set. The page records the announcement and stops there.

How a Free Bet Pays — and What the Stake Coming Back Means

A free bet is the most common reward, and its arithmetic is the one a punter most often misreads.

The free bet is a fixed amount of credit, say £10. It is placed at the price the punter selects, say 4.0. If the bet wins, the bookmaker pays the winnings — £40 in this case — but does not return the £10 stake. The punter walks away with £40. A real-money bet of £10 at the same price would have returned £50: the £40 of winnings plus the £10 stake.

The £10 difference is not a charge. It is the price of the free bet, in the same way that a £5 theatre ticket is not a £5 gift if you paid £10 for it. The expected value of a free bet is the free-bet amount multiplied by the price-minus-one, divided by the price, multiplied by the payout share of the market. For a £10 free bet at 4.0 on a market with a 95% payout share, that is roughly £10 × 3 ÷ 4 × 0.95 = £7.13 of expected value — the average payout over many uses, not what any single bet will pay.

That number matters when comparing offers. A £40 free bet at a 7-day expiry looks better than a £20 free bet at a 30-day expiry, but only if the price available in those seven days matches the price available in thirty. A short window on a thin sport can easily leave the £40 un-staked and therefore worthless.

Minimum Odds and Why They Exist

A welcome offer that asks for a “first bet at minimum odds of 2.0” is using the odds floor to filter the qualifying bet. The bet must be a real prediction, not a coupon-line on a 1/100 shot. The floor is set high enough that the operator does not lose money on the qualifying bet itself.

The floor bites hardest at one moment: the first bet. A punter with a strong view on a match at odds of 1.3 — the favourite is a near-certainty — cannot use that selection to qualify, and has to find a longer price elsewhere. The terms give a few days to do so. The offer is sometimes structured as a £30 free-bet package on a 5p qualifying bet, which keeps the qualifying cost trivial; sometimes as a £40 free-bet package on a £20 bet at 2.0, where the qualifying bet is the more expensive part.

Minimum odds do not apply to the free bet itself. Once the free bet is in the account, it can usually be placed at any price the operator offers, with some operators setting a ceiling (QuinnBet, for example, caps the price on a free bet at 50/1) and some excluding certain bet types (QuinnBet excludes Trixies, Patents and Yankees from free-bet use). The free bet’s stake is never returned with the winnings; that rule does not vary.

The Wagering Requirement, in Plain Terms

The wagering requirement is the multiplier applied to a bonus before withdrawal. A £10 bonus at 5x wagering requires £50 of bets at minimum odds to convert the bonus to cash. A £10 bonus at 10x requires £100. After the 19 January 2026 cap, no GB-licensed bonus may require more than the 10x figure.

The wagering requirement is separate from minimum odds. An offer can carry a low multiplier and a high minimum odds — £10 at 1x but every bet at minimum odds of 5.0 — and that is more expensive to clear than a £10 at 10x and minimum odds of 1.5. The two conditions multiply, in the sense that they both have to be true at once, but the offer does not state a single “cost” number — the punter has to combine them.

The cleanest way to think about it: the wagering requirement fixes how much betting must happen, the minimum odds fixes which bets count, and the expiry fixes how long the punter has to find them. The actual cost of clearing the offer, on average, is the required turnover multiplied by the margin of the market in which the bets are placed. A £100 turnover at a 5% margin costs £5 on average; a £100 turnover at an 8% margin costs £8. The same offer, with the same turnover, costs different amounts at different books.

Welcome Offers at a Glance

The shape of these offers clusters in three ways. Stake-back on a losing first bet is Hollywoodbets’ model, and works well for a punter who expects to lose their first acca but does not want to be punished for it. Matched free bets at Coral and Unibet ask for the largest qualifying stake of the set — £20 at minimum odds of 2.0 — but hand back the largest free-bet bundle (£40). Light qualifying requirements at Sky Bet and BetUK keep the entry cost low but cap the headline number. None of these is uniformly better than the others; each punter will read them differently depending on whether they expect to win their first bet, lose it, or have no strong view either way.

Existing-Customer Offers and What They Cost

The welcome offer is the headline. The ongoing offers are the steady-state experience.

Coral runs a 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. BoyleSports layers Acca Insurance — opt-in, minimum stake £5, minimum odds 1/2, maximum refund £20 as a free bet that expires in 7 days, bet and settlement on the same day — and Acca Loyalty, which pays a free bet on accas of 5+ settled legs and combined odds of 3/1. Spreadex offers acca boosts from 5% to 100% on football accumulators of three or more legs. Kwiff’s Supercharge feature can boost the odds on a bet from 2/1 to 20/1 on the spot.

These ongoing offers are typically stake-not-returned on the free bet and tend to carry lighter terms than the welcome offer — a 1x wagering requirement is common, where it exists. The ceiling is usually tighter, the qualifying bet is usually lower, and the expiry is usually shorter. None of them is a discount on the act of betting. They are marketing spend, given back to the customer as a bundle of bets whose expected value is below their headline.

The honest comparison between two welcome offers is the comparison of expected value, not the comparison of headline number. A £40 free bet at 7-day expiry on a thin sport may be worth less than a £20 free bet at 30-day expiry on a busy one, even though the first number is bigger.

The Cost of Clearing an Offer — Worked Example

Take a representative sign-up bonus: a 100%-up-to-£50 offer, with a 10x wagering requirement on the bonus amount, a minimum price of 1.5 on every qualifying bet, and a 30-day expiry. This sits inside the post-19 January 2026 cap: the wagering requirement is at the ceiling, the minimum price is ordinary for the market, and the structure is the kind a GB punter will meet at one of several operators.

The arithmetic:

• Bonus amount: £50 (the maximum on a 100% match against a £50 deposit).
• Required turnover: £50 × 10 = £500 of qualifying bets.
• Bets needed at a typical £10 stake: 50 bets.
• Expected cost of clearing: turnover × margin. On a typical football 1X2 market with a 5% margin, the expected cost is £500 × 0.05 = £25.

The bonus is worth £50 of headroom against losses, the clearing costs £25 on average, and the net expected value of the offer is somewhere in the region of +£25 — give or take, because the bonus is paid back as cash on completion of the wagering, not as a free bet, and the £25 is the expected drag of margin across 50 bets. The same offer with a 8% margin costs £40 to clear and is worth £10 net. The same offer at a 3% margin costs £15 to clear and is worth £35 net.

The figure is a band, not a single number, because the margin varies market by market and bookmaker by bookmaker. A punter who clears the offer entirely on Premier League 1X2 at a 5%-margin bookmaker is in the middle of the band; a punter who clears on horse racing at a 12%-margin bookmaker is at the bottom. The headline “100% bonus” is the same in both cases; the realised value is not.

This is the information the page can give. The exact figure depends on where the punter places the qualifying bets, and that choice is theirs.

Why the Operator Mixes the Match and Free Bets

GB bookmakers structure their welcome offers in three layers for a reason. The deposit match is a hook, the free bet is the headline, and the minimum-odds clause is the filter.

The deposit match is usually small — £10 to £50 — because it carries the heaviest clearing requirement. The free bet is larger — £20 to £60 — but it is stake-not-returned, so the headline number is twice the realised value. The minimum-odds clause prevents the punter from running the bonus through a 1.01 accumulator and walking away. Each of these conditions exists because the operator has priced the offer to survive them.

The bookmaker’s margin is sitting inside every price on the page, and the bonus structure is a way of paying the punter in margin. A 5% margin on £500 of turnover is worth £25 to the operator; an offer that costs the operator £25 of margin in exchange for a £50 deposit is a profitable customer-acquisition cost. That is not a criticism — it is the shape of the market. The criticism is when an offer is sold with the implication that it is a discount on the betting, rather than a paid-for bundle of bets.

Safer Gambling Tools and Where to Find Help

Every GB-licensed operator in this comparison offers the same baseline: deposit limits, time-out periods, and access to GAMSTOP for self-exclusion. GAMSTOP is the national multi-operator self-exclusion scheme, mandatory for online operators since 31 March 2020. Exclusion periods run 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. The scheme covers online sites and apps; betting shops use a separate service.

DAZN Bet, for one, provides deposit limits, loss limits and wagering limits as safer-gambling tools. Most other brands in this comparison carry equivalent tooling, with the same vocabulary. These are customer-set limits, not a state-set ceiling — there is no statutory deposit or loss cap for GB sports betting, and never has been.

For help, GamCare runs the National Gambling Helpline. GambleAware funds treatment and research. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings. Each of these is free; each takes self-referrals.

The Licence Check, in Three Steps

A punter who wants to confirm that a brand is licensed in Great Britain can do so in three steps on the Commission’s public register.

First, search by trading name. The register is searchable at the Commission’s site by business name, trading name, domain or account number. The site’s URL is not enough on its own — licensed operators use both .co.uk and .com domains.

Second, check the licence type. A GB-licensed sportsbook will hold a remote general betting standard (real events) licence; a betting exchange will hold a remote betting intermediary licence; a financial spread-betting product will also be regulated by the FCA. The licence type matters because some offers (financial spread betting, in particular) cross regulatory regimes.

Third, read the conditions. The Licence Conditions and Codes of Practice set the floor for player protection, marketing and identity checks. The Commission’s enforcement notices show where operators have fallen below those conditions. None of this is on the marketing page; all of it is on the register.

What “Risk-Free” Usually Means

“Risk-free” is the marketing word most worth puncturing.

A risk-free bet, in the GB market, is usually a stake-back offer: the first bet loses, and the stake is returned as a free bet. The first bet is not free — it was placed with real money at real odds, and it lost. The stake returned is a free bet whose stake will not be returned again if it wins. The offer is “risk-free” in the sense that the punter does not lose the entire stake, but it is not free in the sense that the punter walks away with the headline number.

The honest reading: a £10 stake-back offer on a £10 bet at evens is worth, on average, somewhere between £3 and £5 after the stake-not-returned rule and the market margin. The headline number — “bet £10, get £10 back” — suggests a wash. The arithmetic says otherwise.

The same word crops up in “risk-free” accumulators and “risk-free” each-way bets. The pattern is the same: a stake-back in the form of a free bet, whose own stake will not be returned. The word does not mean what it sounds like. Read the terms.

What Offshore Sites Cannot Offer

A GB licence is compulsory at the point of consumption, not the point of operation. 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 for a GB licence for a customer in Great Britain.

The page does not recommend offshore sites and does not list them. The reason is structural: an offshore site is not covered by GAMSTOP, has no Commission complaints route, has no approved dispute-resolution body, has no obligation under the £150 vulnerability check, and is not bound by the 10x bonus cap. The punter’s recourse if funds are withheld is whatever the operator’s own terms say, with no British consumer redress to fall back on. None of this makes an offshore site illegal to use; it does mean the protections a licensed site offers are absent.

Enforcement of the British regime is not consumer-facing. The Commission issues cease-and-desist notices, works with search engines and payment providers, and has been given or is about to receive court-order DNS blocking powers. ISP blocking is not in operation and the page does not write as if it were.

The Comparison Set, Operator by Operator

What follows are ten operator reviews, in the order the data puts them, each closing on what the spec actually established — the offer’s cost, the licence’s specifics, or the gap that separates this brand from its neighbour. Each is reviewed as a standalone product; nothing here is a recommendation.

Unibet

Unibet’s UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The brand has operated since 1999 in some form, and the GB product is the mature end of that history. The welcome offer is £40 in free bets when a £20 sports bet is placed at minimum odds of 2.0, with free bets expiring within 7 days, for new GB customers using a debit card or instant bank transfer.

The headline matches Coral’s headline — same £40-against-£20 structure, same minimum price, same 7-day expiry — but the platform carries a wider feature set: Bet Builder, daily Uniboosts, in-play betting, live streaming through Unibet TV, Best Odds Guaranteed on horse racing, and Cash Out on thousands of markets. The £20 qualifying bet at 2.0 is the heavier side of the comparison set; the £40 free bet is the larger side. Whether one punter’s £20-at-2.0 is worth more or less than another’s £10-at-1.5 depends entirely on what that first bet is.

The 7-day expiry on the free bets is short for a punter who wants to wait for a specific match. The 7-day window at Coral carries the same constraint. For a punter who already has a betting card for the weekend, neither constraint bites. For a punter who bets once a month, the constraint costs the offer.

Verdict: a heavy qualifying bet in exchange for the largest free-bet bundle in the comparison set, wrapped around a feature-dense platform that justifies the £20 entry for a punter who would use Bet Builder, in-play and live streaming anyway.

Paddy Power

Paddy Power’s UK site runs under Gambling Commission account 39439, held by PPB Counterparty Services Limited. The app showcases Bet Builder+, Popular Bet Builders, Super Sub — a bet rolls over to the replacement if a selected player is substituted — expanded Win More markets, and player and ACCA stats. The platform’s edge is its feature set rather than a single welcome number.

The app is the same product family as Betfair’s, both under Flutter. A punter looking at Paddy Power is also implicitly looking at a sister-brand exchange at Betfair, which has its own pricing and its own welcome offer. The two are not the same company for the punter’s purposes — they are different apps with different markets — but they are not independent operators either, and a comparison that lists one without the other is not quite complete.

Verdict: the platform choice when the welcome offer is secondary to the feature set — Bet Builder+, Super Sub and the in-play depth are the things being bought, with the welcome offer as the entry.

Copybet

Copybet operates under Gambling Commission account 53774, held by Copybet UK Limited. The platform’s signature feature is the Acca Booster, which pays up to a 100% cash bonus on accas of at least 3 selections, and the Daily Profit Boost, which pays up to 15% on selected markets.

The Acca Booster is paid in cash, not as a free bet, which sets it apart from the stake-not-returned model used by most welcome offers. A 100% cash boost on a winning 5-fold is a real return, not a credit to be cleared through a wagering requirement. The Daily Profit Boost is a smaller, more frequent feature.

Verdict: the platform choice when acca betting is the primary activity and a cash bonus is worth more than a free-bet bundle.

London Bet

London Bet is published by Thistle Bet Limited, under Gambling Commission account 66162. The site states it is licensed and regulated in the UK; its app carries a 17+ App Store age rating. The product is a smaller-scale sportsbook, and the welcome terms are stated on the operator’s own page rather than across the comparison set.

The platform sits in a different shape of the market. It is a UK-licensed bookmaker, fully compliant with the Commission’s rules, and not the largest brand in any one product line. A punter choosing London Bet is choosing a smaller operator with a focused product rather than a feature-dense giant.

Verdict: a smaller-scale UK-licensed bookmaker, suitable for a punter who wants a focused product and is comfortable with a brand that is not on every billboard.

Betway

Betway operates under Gambling Commission account 39372, held by Betway Limited. The welcome offer is £40 in free-bet tokens (4 × £10) 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 four-tokens structure is a marketing convenience: each token is a single free bet, and four tokens give the punter four separate shots at the betting card. Whether four £10 tokens are worth more than one £40 token depends on the punter’s habits. A punter who wants to spread the free bets across a weekend gets four chances; a punter who wants to put the lot on one match gets one chance.

The minimum odds of 2.0 and the £10 qualifying bet put Betway in the middle of the qualifying-bet pack. The 7-day expiry on the free bets is short. The debit-card restriction is the same as every other GB bookmaker.

Verdict: the standard £40-in-free-bets shape, packaged as four tokens for a punter who would use four free bets rather than one.

10bet

10bet operates under Gambling Commission account 43173, held by Blue Star Planet Limited. The app advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins.

The 100%-up-to-£50 is a deposit-match bonus, not a free-bet bundle. It carries the heaviest wagering requirement of the set, even at the post-19 January 2026 10x cap — a £50 bonus at 10x is £500 of qualifying bets. The daily free bets and free spins are ongoing offers on top.

Verdict: the deposit-match route, for a punter who prefers bonus credit to a free-bet bundle and is willing to clear the wagering requirement.

BetVictor

BetVictor operates under Gambling Commission account 39576, held by BV Gaming Limited. The app offers regular price boosts, acca offers and free bets on selected events; welcome offers are shown in the app and governed by the customer terms and conditions.

The platform’s edge is its long history in the GB market and its spread of ongoing promotions rather than a single headline welcome. A punter choosing BetVictor is choosing a steady-state experience of weekly boosts and acca offers, with the welcome as the entry.

Verdict: the long-running GB bookmaker for a punter who values ongoing offers over the headline welcome number.

Hollywoodbets

Hollywoodbets operates under Gambling Commission account 53028, held by Hollywoodbets International UK Limited. The 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 is the inverse of the matched free bet: the punter is betting on the first acca losing, and the bookmaker returns the stake as a free bet if it does. The £30 ceiling caps the returned stake at 3x the qualifying bet. The 4/1 minimum combined odds and the 3-leg minimum are real filters — a 2-leg acca at 3/1 does not qualify, even if it loses.

Verdict: the stake-back offer for a punter with a strong view on a 4/1+ acca who expects to lose it.

BetUK

BetUK operates under Gambling Commission account 39198, held by LeoVegas Gaming PLC. The sports welcome offer: new customers who deposit £10 or more and place a sports bet within 7 days of registering receive four £10 free bets — two football accumulators of 4+ selections and two multiples of 2+ — valid for 7 days, with opt-in required.

The four-tokens structure is allocated to specific bet types, not to the punter’s choice. The punter gets two football accas and two multiples, and cannot use the tokens on, say, a horse-racing single. The 7-day window on the qualifying bet and the 7-day window on the free bets are both short.

Verdict: a football-focused welcome for a punter who bets accas and multiples, with the token allocation reflecting that shape.

Sky Bet

Sky Bet operates under Gambling Commission account 67370, held by SBG Sports Limited. The welcome offer: £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater.

The 5p qualifying bet is the lightest in the comparison set — the punter’s exposure on the first bet is 5p, not £10 or £20. The £30 free-bet total is the smallest. The trade-off is that the qualifying bet costs almost nothing, so the punter is not gambling their own money to qualify. A punter who is risk-averse on the first bet and patient on the free-bet use is the target.

Verdict: the lightest qualifying bet in the comparison set, for a punter who wants the welcome bonus unlocked at near-zero cost.

What the Comparison Reveals

The headline numbers of the welcome offers cluster around three figures: £30, £40 and £60. The qualifying bets cluster around three figures too: 5p, £10 and £20. The product is the same — a bundle of free bets or a deposit match — but the package varies by qualifying cost, expiry window, token structure and minimum price.

The smallest qualifying cost (Sky Bet, 5p) is paired with the smallest free-bet bundle (£30). The largest free-bet bundle (Sky Bet, £60 — through SBK, the Smarkets sportsbook) is paired with a heavier qualifying cost (£20 at minimum odds of 3.0, settled within 48 hours). The deposit-match offers (10bet at 100% up to £50) sit at the heavier end of the wagering requirement, even at 10x.

A punter who values the welcome offer as a discounted entry picks the brand with the smallest qualifying cost relative to the free-bet bundle. A punter who values the welcome offer as an introduction to a platform they would use anyway picks the brand with the strongest feature set. A punter who treats the welcome as a marketing cost they don’t want to pay picks the brand with the lightest qualifying bet, regardless of the bundle.

None of these is universally correct. The page does not pick.

How the Free Bets Sit Against the Margin

The book’s margin is sitting inside every price the punter takes, and the free bet is no exception. A free bet at 4.0 on a 5%-margin market returns £40 of winnings on a £10 free bet, of which £7.13 is expected value after the stake-not-returned rule and the market margin. The same free bet at 4.0 on a 12%-margin market returns the same £40 of winnings — the price is the price — but the realised value is lower, because the market’s margin has been taken out across the bet’s expected payout.

The honest comparison is between offers at the same price on the same market, not between offers at different prices on different markets. A £40 free bet on a thin sport with high margins is worth less than a £30 free bet on a deep sport with thin margins, and the difference is invisible in the headline number.

The Bonus Turnover, Recalculated

The plan’s prescribed calculation takes Coral’s £40-in-free-bets offer as the worked example. With a £20 qualifying bet at minimum odds of 2.0 (1/1), the free bet is issued within 7 days and expires 7 days after issue.

The arithmetic:

• Qualifying bet: £20 at minimum odds of 2.0, settled at the price taken.
• Free bet issued: £40, credited as free-bet tokens.
• Wagering requirement on the free bet: none stated — the free bet is stake-not-returned by structure, not by a wagering multiple.
• Wagering cap: 10x on bonuses, per the Commission’s 19 January 2026 rules. Whether this applies to free bets with no wagering condition is not established.
• Expiry: 7 days from issue.
• Expected value: with four £10 tokens at an average price of 3.0 on a 5%-margin market, the bundle is worth £7.13 per token, or roughly £28.50 across the four. The £40 headline is the marketing number; £28.50 is the realised value.

The free bet is not subject to a turnover requirement under the operator’s own terms, so the calculation collapses to expected value rather than expected cost. A punter who clears the free bets at high-margin markets ends up at the bottom of the band; a punter who clears at low-margin markets ends up at the top. The 7-day expiry is a real constraint: a punter who waits past it walks away with nothing.

The wagering cap question is open. The Commission’s published guidance on the 19 January 2026 rules did not state whether free bets with no wagering condition are caught by the 10x ceiling. Operators’ own terms are the only source for the answer, and the terms vary. Coral’s free bet is not subject to a stated wagering multiple; 10bet’s deposit bonus is, at the post-cap 10x. The two are different products under the same rule.

A Final Reading of the Numbers

The numbers on this page are three: the welcome bonus, the qualifying bet, and the expiry window. They are the three figures a punter reads. What they cost — the turnover, the margin drag, the realised value — is what a punter does not see.

A £40 free bet at 7-day expiry is the same headline number at every operator that runs it. It is not the same realised value. A punter who clears it at 3.0 on a deep market walks away with £30 of expected value; a punter who clears at 1.5 on a thin market walks away with £15. The bookmaker’s margin is the difference. The page’s job is to make that difference visible.

The £150 vulnerability check, the GAMSTOP membership, the 10x bonus cap and the credit-card ban are not marketing features. They are the floor that every GB-licensed operator sits on. A punter who bets with a licensed operator is betting with that floor under the offer. A punter who bets without it is betting without it. The page does not pick a side; the licence check does.

Frequently Asked Questions

How do I use a promo code at a betting site?

Most GB-licensed bookmakers no longer use promo codes at the sign-up stage. The welcome offer is activated by depositing through a qualifying payment method, placing a qualifying bet at the stated minimum price, and opting in where the offer requires it. The promo code, where one exists, is entered during registration or in the cashier; the offer terms will state which. The Commission does not require a code as part of the offer, and the absence of a code does not mean the offer is missing. Always check the offer terms on the operator’s own page before depositing, because the qualifying conditions vary by brand.

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

The Gambling Commission’s promotion rules, in force since 19 January 2026, cap wagering requirements on bonuses at 10x. A £10 bonus may not require more than £100 of qualifying bets before the bonus converts to withdrawable cash. The cap is on the multiplier, not the bonus amount; a 100%-up-to-£50 bonus carries a £500 maximum turnover. Whether the cap applies to free bets with no wagering condition is not established in the Commission’s published guidance; operators’ own terms are the only source for that point.

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

The wagering requirement is the multiplier on the bonus before it converts to cash — for example, a £10 bonus at 5x needs £50 of qualifying bets. Minimum odds is the lowest price at which a qualifying bet counts toward that turnover — for example, a minimum odds of 1.5 means only bets at 1.5 or longer count. The two multiply, in the sense that they both have to be true at once: a punter cannot run a £100 turnover through 1.2 shots, and cannot satisfy a 5x requirement with a single £50 bet. The two conditions together fix the cost of clearing the offer.

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

A free bet is a fixed amount of credit, placed at the price the punter selects. If the bet wins, the bookmaker pays the winnings — calculated as stake × price — but does not return the stake itself. A £10 free bet at 4.0 pays £40, against a real-money £10 bet at the same price paying £50. The £10 difference is the price of the free bet, not a charge. The expected value of a free bet is the stake multiplied by the price minus one, divided by the price, multiplied by the market’s payout share.

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

No. Since 19 January 2026 the Gambling Commission’s promotion rules ban mixed-product promotions — any offer that requires gambling on two or more product types such as betting, casino, bingo and lottery. A free bet contingent on a sports bet at a minimum price is permitted; a free bet contingent on a sports bet plus a casino deposit is not. The rule is about the structure of the offer, not the size of the prize, and applies to every GB-licensed operator.

How can I check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is searchable by business name, trading name, domain or account number. Search by trading name first; confirm the licence type (remote general betting standard, remote betting intermediary, etc.); read the conditions and any open enforcement notices. The register is the whole test of whether a brand holds a licence, and the licence types are listed against each entry. The domain alone is not proof — licensed operators use both .co.uk and .com domains.
