The phrase “promo code” gets thrown around as if signing up were the hard part. It isn’t, and the code itself is the smallest thing on the page. What sits behind the code is a free bet, a sign-up offer or a price boost, and what each of those is worth depends on rules the Gambling Commission has tightened hard since 19 January 2026 — a 10x cap on bonus wagering, a ban on offers that mix betting with casino, bingo or lottery, and stricter identity and affordability checks at the till. The ten bookmakers in this guide hold a Gambling Commission remote licence for Great Britain, describe the offers only as their own terms state them, and are the ones a UK punter will actually meet when looking for a free bet, an acca boost or a sign-up deal in 2026.

Current as of October 30, 2026 — verified against the Gambling Commission’s public register and each operator’s own terms page.

The Honest Lead: What the Commission Changed in 2026

Two changes from the Gambling Commission, both effective 19 January 2026, do more to shape the value of a betting offer than any bookmaker’s marketing line. They sit at the top of this guide on purpose, because every offer further down the page runs through them.

First, wagering requirements on bonuses are capped at 10x. A bonus is the part of a deal a punter must turn over — bet through — before any winnings become withdrawable. Under the cap, a £10 bonus at 50x required £500 of betting before withdrawal; under the cap no more than £100 of turnover is needed, and the offer cannot legally require more. A £20 free bet credit with no rollover at all, the kind Bet365 and Sky Bet issue for opt-in events, does not fall under the cap because nothing has to be turned over. Whether the cap applies to a free bet whose only condition is “use it once at minimum odds” remains unsettled, and is described as such by the Commission itself.

Second, mixed-product promotions are banned. An offer that asks a punter to bet on football to claim free spins in a casino, or to place a sports acca to unlock bingo credit, is no longer permitted at any Commission-licensed operator. The ban applies to the operator offering it, not to the customer taking up something else separately.

Alongside the promotion rules, two player-protection changes make claiming an offer slower than it used to be. Identity verification runs before the first deposit, so the email-and-go sign-up is gone. A financial vulnerability check — a public-record scan for things like county court judgments and bankruptcy, not an income or credit check — kicks in once deposits minus withdrawals cross £150 in a rolling 30-day window. These apply even when a punter only wants a free bet.

The promotion cap and the mixed-product ban together narrow the territory an offer can occupy. A “bet £20, get £40 in free bets” deal, the kind Coral, Unibet and BoyleSports run, fits inside the rules. A combined sports and casino welcome package, increasingly common outside Great Britain, does not.

Responsible Gambling: The Tools Behind the Offer

A betting promo code is a marketing device, but the betting account it sits inside is a regulated product. Three layers of protection shape how a punter uses any offer, and each one has been rewritten in the last few years.

GAMSTOP is the national multi-operator self-exclusion scheme and a mandatory licence condition for every online bookmaker since 31 March 2020. Self-exclusion can be set for six months, one year, five years, or five years with auto-renewal. Once the minimum period is up, the exclusion continues for a further seven years unless the customer asks GAMSTOP to lift it. GAMSTOP covers online sites and apps; the high-street betting shop uses a different service. A punter who has registered with GAMSTOP cannot open an account at any GB-licensed online bookmaker for the duration of the exclusion, including to claim a welcome offer.

Deposit limits are a customer-set ceiling on how much can be paid into an account within a fixed window. The Commission requires every licensed operator to offer them. Two phases of stronger rules have applied since 31 October 2025, with a second phase postponed to 30 September 2026; whether the second phase is live at the moment of reading is not settled, so the rule is described as “in force from 31 October 2025, with further changes pending”. Limits are the customer’s choice, not a state-set number, and a punter can set a tighter window than the operator’s default.

Financial vulnerability checks and financial risk assessments are different steps on the same ladder. The vulnerability check applies once deposits minus withdrawals cross £150 in a rolling 30 days and runs against public records. Financial risk assessments — the affordability checks reported in the press — sit further along, in a Commission plan announced on 7 July 2026 with no start date. They are described as “announced, staged, no start date”, and not as in force.

Help exists outside the operator. GamCare runs the National Gambling Helpline. GambleAware funds treatment and support. The NHS runs gambling clinics across the regions. Gamblers Anonymous runs peer-led meetings. None of these is an offer, and none is a marketing channel; they exist because the Commission requires safer-gambling messaging on every advertisement, and the operators themselves signpost them in their apps.

Bonuses and Free Bets: The Mechanics the Marketing Skips

A betting promo code is one way to switch on an offer; a click-opt-in button is the other, increasingly the default. Either way, what switches on is a structure, and the structure is what determines the value.

A free bet is a one-shot stake the bookmaker credits to the account. Its stake is not paid back with the winnings. A £10 free bet at odds of 3.0 returns £30, not £40 — the £10 stake vanishes once the bet is placed, and the punter keeps the £20 profit. The expected value of a free bet is roughly the free-bet amount multiplied by the odds minus one, divided by the odds, then by the payout share of the market the bet is placed in. On a typical Premier League match market with a 95% payout share, a £10 free bet at odds of 4.0 is worth about £7.10 on average over many placements, not £30. That is the upper bound of what the offer is worth, and the marketing copy never mentions it.

A sign-up offer is a free bet or series of free bets conditional on a first deposit and a first qualifying bet. Coral, Unibet and BoyleSports run variants of “bet £20, get £40 in free bets”; Sky Bet runs “£30 in free bets for a £5 first bet”; Betfair runs a £20 free bet for a £5 first bet. Each has a minimum odds floor on the qualifying bet — Coral and Unibet set it at 2.0 (1/1), BoyleSports and Spreadex at 1/2. Each has a deadline — Coral issues its free bets within 7 days and the free bets expire 7 days after that; BoyleSports opens 7 days for both.

An accumulator boost is a percentage added to the winnings of an acca. Spreadex adds 5% to 100% on football accas of three or more legs depending on size; William Hill runs a Football Acca Boost from 3% on a double up to 200% on 20 or more legs, with a £10,000 cap per online bet, running until 30 May 2027. Acca insurance refunds a stake as a free bet if one leg lets the punter down. BoyleSports Acca Insurance asks for opt-in, a £5 minimum stake, 1/2 minimum odds, settles on the same day, and refunds up to £20 as a free bet expiring in 7 days.

A price boost lifts the odds on a single selection, often to a headline-grabbing figure. Kwiff’s Supercharge feature does this on the fly, lifting a price from 2/1 to 20/1 on selected bets. Bet365 runs Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. Midnite runs price boosts with maximum-stake limits published on the event card.

A risk-free bet, where it is offered, refunds a losing stake as a free bet rather than as cash — which means the free-bet rule above applies and the stake is not returned. Marketing copy tends to call such offers “risk-free” in bold and bury the mechanic in the small print; this guide does the reverse.

Minimum odds on a qualifying bet exist because bookmakers will not pay a free-bet reward for a punter who places a qualifying bet at odds of 1.01 and walks away. The floor filters out the “stake-and-cash-out” claim path. Once the offer is triggered, the free bets themselves carry their own minimum-odds rules — QuinnBet free bets are valid for 7 days from credit, on any market at 1/2 (1.5) or greater, with maximum odds of 50/1, and straight accumulators are allowed but Trixies, Patents and Yankees are not.

The maths in plain prose. The Coral offer is a useful worked example, and the page works it through because it is the kind of structure most of these sign-ups follow. Coral credits £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 (1/1); the qualifying bet is the trigger and is paid back as a normal win or loss; the £40 in free bets is the reward. Assuming the punter places the £20 qualifying bet at odds of 2.0, the qualifying bet pays £40 if it wins (£20 profit) or nothing if it loses, with no turnover requirement. The £40 in free bets is then split as Coral’s terms state, and each free-bet token carries its own expiry of 7 days from issue. The stake of each free bet is not returned on a win. The expected value of the reward depends on what odds the punter takes on the free bet and on the margin of the market it is placed in; the headline £40 is the gross amount credited, not the expected value.

What the bonus cap means in practice. The 10x cap, in force since 19 January 2026, applies to wagering requirements. None of the sign-up offers above carries a wagering requirement on the free bet itself — the £40 from Coral and Unibet, the £30 from Sky Bet, the £20 from BoyleSports and Spreadex are free bets, and free bets in their standard form are not turned over. The cap matters most where an offer credits bonus cash with a rollover, the kind of structure more common in casino welcome packages than in sports sign-ups. A £10 bonus cash with a 10x rollover needs £100 of qualifying bets; the same bonus under the old 50x rule needed £500. A punter who has been offered bonus cash rather than free bets should check whether a rollover applies before committing the deposit.

The Top 10 Licensed UK Bookmakers — Side by Side

The table below compares the ten bookmakers on the basis the offer hinges on: who holds the licence, and what the operator’s own terms say about the welcome deal. Minimum odds, free-bet expiry and qualifying-bet conditions are read off each operator’s terms page. The licence number is the account number on the Gambling Commission’s public register, and is the way to verify the brand. Prices on a regular site change faster than this page can follow, so they are not pinned here.

The licence numbers in the second column are the account numbers on the Commission’s public register. Any bookmaker offers a free bet, and none of them opens an account until the punter passes identity and age verification; the verification runs before the first deposit, so the headline “bet £X to get £Y” needs an ID to hand. The welcome offers are described as each operator’s own terms state them — minimum odds, free-bet expiry and qualifying-bet conditions sit in those pages, and the smaller print of each deal is the difference between a credited reward and a forfeited one.

The pattern worth seeing is that all ten hold a Commission licence in the same broad category — remote general betting standard (real events) — with Smarkets sitting one category over as a remote betting intermediary. Smarkets is the only exchange on the list; the rest are traditional bookmakers. Betfair runs a sportsbook alongside its exchange, but it is a sportsbook on this list rather than an exchange.

The Wider Landscape of UK Betting Promo Codes

Outside the top ten, the Commission’s public register lists several hundred more remote betting licences for Great Britain. The ten above are the ones a punter will meet first when searching for a sign-up offer, a free bet or an acca boost, and they sit at the centre of the comparison for that reason. The promotion rules and identity checks above apply to all of them identically. A licensed bookmaker who does not appear here is not offering less protection; it is offering less prominence, and the punter’s own comparison is the way to find the right fit for the bets they place.

Three groups sit around the ten. The first is the high-street names whose online arms run alongside Ladbrokes, Coral, Paddy Power and Betfair, William Hill, Sky Bet, Betfred and Betway; Ladbrokes and Coral share a licensee, and Paddy Power and Betfair share one, so a punter who already has an account at one of these cannot usually claim a welcome offer at the other. The second is the new-entrant cluster — Midnite, Kwiff, Bet600 and the rest — where the welcome offer is typically the strongest hook and the ongoing promotions are thinner. The third is the exchange — Smarkets and Betfair — where the welcome is smaller and the price is the point, because the exchange takes a commission on net winnings rather than a margin baked into every price.

A bookmaker without a Commission licence is a different decision. The Commission’s promotion rules, the 10x cap, the GAMSTOP coverage and the identity checks do not apply offshore, and the licensed-on-Curaçao brand runs on its own house rules. The punter loses the bonus cap, the public-register check, the GAMSTOP coverage and the Commission’s complaints route, and gains nothing in return. An offer on an unlicensed site is not “the safe choice” — neither is a licensed site by default, because verification is mandatory and slower — and the difference is structural rather than marketing.

Legality and Regulation in Great Britain

The Gambling Commission regulates the whole commercial market under the Gambling Act 2005, which covers Great Britain — England, Scotland and Wales. Northern Ireland sits outside the Act under older law, so a GB licence does not regulate betting there. 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. There is no state monopoly and no cap on the number of licences, so the register is long.

The five licence categories relevant to online sports betting are remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting and remote betting intermediary — the last being the licence for exchanges. Most of the ten sit in the first category; Smarkets sits in the last. The Commission’s public register is searchable by business name, trading name, domain or account number, and is the whole test of whether a brand holds a licence. A licensed operator can use .com as well as .co.uk, so the domain itself proves nothing.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission — that is why Spreadex holds both an FCA authorisation for spread betting and a Commission licence for fixed-odds betting. The minimum age is 18. Identity verification (name, address and date of birth) runs before the first deposit, including when the first action is to claim a free bet, and is a condition the Commission put in place on 7 May 2019.

What may be bet on. No statutory list of permitted bets or markets exists; an operator holds a licence for a category and offers markets under its own rules and the Licence Conditions and Codes of Practice (LCCP). In-play betting is offered by every GB bookmaker and is governed by the operator’s licence conditions and customer-protection duties. Esports are treated like any other event; virtual events sit under a separate licence category; bets on politics, TV shows and novelty markets are offered by some GB bookmakers and no statutory prohibition has been published. Betting exchanges run under a betting-intermediary licence; rates and rules specific to exchanges are stated only from each exchange’s own terms. Spread betting that is not a financial product is inside General Betting Duty. Off-course pool betting on horse or dog racing sits under a separate licence and duty. No statutory cap on stakes in sports betting has been published; operators set their own maximum stakes and may restrict individual customers.

Advertising and bonuses. Advertising is not licensed by the Commission; it runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the LCCP marketing conditions. CAP Code section 16 sets the tone — marketing must be socially responsible, must not strongly appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling in the advertisement or play a significant role (with an exception for marketing placed where a bet can be placed directly). The promotion rules in force since 19 January 2026 are the 10x cap on bonus wagering and the ban on mixed-product promotions described above. “Whistle-to-whistle” — no betting advertising 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 — is an industry code in force since 1 August 2019, not a statute. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts from the 2026/27 season is voluntary.

Tax. The player pays no tax on betting winnings in Great Britain; the operator pays General Betting Duty on gross profits at 15%. From 1 April 2027 a remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15% — a policy announced by HM Government on 26 November 2025. Spread betting has its own rates (3% financial, 10% other). Until 1 April 2027 the remote rate stays at 15%; whether operators pass duty on through odds is not established, and the customer is not charged duty by the operator. The Commission’s statutory levy is a separate charge, not a tax.

Enforcement offshore. 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) and is aimed at the operator. No offence aimed at the customer who merely bets on an unlicensed site has been published; the loss of protection — no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, not bound by the 10x bonus cap or the £150 vulnerability check — is the framing the Commission uses. Enforcement is disruption, not blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers. The Commission has been given, or is about to receive, court-order DNS blocking powers, and ISP blocking is not in operation.

Hollywoodbets — Stake Returned on a Losing First Acca

Hollywoodbets holds Commission licence 053028-R-330019-013, with Hollywoodbets International UK Limited as the licence holder. The brand is South African in origin and runs the UK site under the licence cited. The welcome offer is stake-returned as a free bet on a first qualifying losing accumulator: new players who deposit £10 or more by card get their stake back as a free bet of up to £30 if the first qualifying acca loses. The qualifying accumulator needs three or more legs, odds of 4/1 or greater, settled within 7 days. One free bet per customer. There is no wagering requirement on the returned stake; the free bet carries its own minimum-odds rule and its own expiry under Hollywoodbets’ terms.

The offer is unusual because the trigger is a losing bet rather than a winning one, and the reward is the stake itself rather than a fixed free-bet credit. A punter whose first acca wins does not get the free bet; a punter whose first acca loses does. The 4/1 floor on the combined odds filters out short-priced favourites, and the £30 cap on the returned stake keeps the offer from running away if the qualifying acca is a large stake at long odds.

Hollywoodbets is a sound pick for a punter whose first instinct on opening a new account is to place a small acca and see what happens. It is less useful as a destination for ongoing promotions, since the brand’s UK presence is built around the welcome rather than a steady stream of acca boosts or price boosts.

Fitzdares — Same-Day Visa Withdrawals and a Premium Feel

Fitzdares holds Commission licence 000400-R-103839-030, with Fitzdares Limited as the licence holder. The brand runs a higher-end positioning with a small sportsbook and a focus on horse racing. Payments run through Apple Pay, Mastercard and Visa; Visa withdrawals are usually same-day, Mastercard withdrawals can take up to 48 hours. The welcome offer is stated in the app; the headline figure sits inside a longer terms page and is not published in the way Coral’s is.

The same-day Visa withdrawal is the operative feature for a punter who values fast access to winnings over headline offer size. The 48-hour ceiling on Mastercard is the trade-off. The brand’s commission licence is the oldest on this list by account number, which signals longevity rather than current scale.

Fitzdares suits a punter who bets mostly on racing and wants their winnings the same day rather than two days later. The punter looking for the largest sign-up free bet will find better headline numbers elsewhere; the punter looking for fast settlement will not.

Tote — Pool Betting for a Racing-Led Account

Tote holds Commission licence 054779-R-331321-008, with TDCO Limited as the licence holder. The brand is the pool-betting specialist, the place a punter goes for a stake on the tote pool on a race meeting rather than a fixed-odds price. The site also offers fixed-odds markets, but the brand’s identity is the pool. Welcome offer and BOG-style promotions are read off tote.co.uk; the brand does not run the same headline sign-up structure as Coral or Unibet.

A punter who wants a free bet on a football acca is on the wrong site. A punter who wants a stake on the pool for the 3.15 at Newmarket with the chance of a bigger payout on a popular horse is on the right one. The trade-off is structural rather than promotional.

Tote is the right home for a pool-led punter. The punter looking for a free-bet sign-up will not find the offer here.

BetVictor — Regular Boosts and Acca Offers Across Events

BetVictor holds Commission licence 039576-R-319370-028, with BV Gaming Limited as the licence holder. The brand runs regular price boosts, acca offers and free bets on selected events; the welcome offer is shown inside the app and governed by the operator’s customer terms. The bookmaker is one of the longer-established names on the Commission register and one of the longer-established on this list.

The “regular” framing matters. A boost on a Tuesday evening Premier League game, an acca offer on a Saturday afternoon, a free bet on a Champions League night — BetVictor’s pitch is that the offer is in the calendar rather than at the front door. The welcome offer inside the app is a starting point; the running value is in the weekly boost schedule.

BetVictor suits someone who has set up their account already and is looking for ongoing value rather than a one-shot sign-up. The punter who wants the headline sign-up will find bigger numbers elsewhere.

Bet600 — Five Qualifying Bets to Unlock One Free Bet

Bet600 holds Commission licence 044731-R-323941-016, with Tyche Tech Limited as the licence holder. The brand’s app welcome offer requires at least 5 qualifying single bets of £10 or more at Evens (2.0) or greater within the first 7 days of registration, after which one £10 free bet is credited. The qualifying bets are singles, not accas, and the minimum odds are 2.0 across the five.

The structure is heavier than the standard “bet £20, get £40” sign-up. Five qualifying singles is five bets the punter must place and settle, not one. A punter who only places accas will not unlock the free bet without placing five singles first. A punter who places singles regularly will reach it without thinking.

Bet600 is a fit for the punter whose betting pattern is singles rather than accas. The punter whose pattern is accas will find the requirement awkward.

Fitzwilliam Sports — Dublin-Based, Membership-Capped

Fitzwilliam Sports holds Commission licence 048760-R-335434-009, with SBKI Limited as the licence holder. The brand describes itself as a Dublin bookmaker with capped membership and offers a “High Stakes Welcome” subject to compliance criteria. The capped membership is the structural feature: the brand is not open to everyone, and the welcome is sized for the punter it does open to.

A punter who is admitted gets a higher-stakes welcome than the standard sign-ups. A punter who is not admitted does not get a welcome at all. The compliance criteria sit between the punter and the offer, and the brand’s terms state them.

Fitzwilliam Sports is a fit for the higher-stakes punter who has been admitted. The punter looking for an open sign-up is on the wrong site.

Betfair — Exchange and Sportsbook in One Brand

Betfair holds Commission licence 039439-R-319330-013, with PPB Counterparty Services Limited as the licence holder — the same licensee as Paddy Power, which is why the brands share back-office functions. The sportsbook offers in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football inside the app, and a 90 Minute Payout market on selected football events. The exchange is the older of the two arms and the larger by liquidity; the sportsbook sits alongside it.

The 90 Minute Payout market is the structural feature: a bet on the match result pays out at the 90-minute whistle regardless of extra time or penalties, which matters on cup ties that go the distance. The exchange’s commission model is a different beast from the sportsbook’s margin; the welcome offer is sized for the sportsbook arm.

Betfair suits a punter who already uses the exchange and wants a sportsbook under the same roof. The punter looking for the largest sign-up free bet will find better headline numbers at Smarkets via SBK.

Smarkets via SBK — Exchange Liquidity in a Sportsbook Wrapper

Smarkets holds Commission licence 039173-R-319366-011, with Smarkets (Malta) Limited as the licence holder. The brand runs the SBK sportsbook, whose UK welcome offer is £20 first deposit and a £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. The Commission licence category is remote betting intermediary, the exchange category, rather than the standard bookmaker category — the only operator on this list to sit there.

The minimum-odds bar is set higher than Coral’s and Unibet’s 2.0; a punter whose qualifying bet is at short odds will not unlock the £60. The £20 deposit, £20 bet, £60 free-bet reward structure sits between Coral’s “bet £20, get £40” and a more aggressive sign-up, and the 48-hour credit window is short.

Smarkets suits a punter who wants exchange pricing in a sportsbook wrapper. The punter looking for a low-qualifying-bet welcome will find the 3.0 minimum harder to clear than the 2.0 minimums elsewhere.

LiveScore Bet — Wide Payment Choice, In-App Welcome

LiveScore Bet holds Commission licence 056859-R-332720-005, with LiveScore Betting and Gaming (Gibraltar) Limited as the licence holder. The brand accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay — the broadest payment choice on the list. The welcome offer sits in the app rather than on a fixed landing page.

The payment breadth is the operative feature for a punter whose bank is locked out of gambling transactions by default; Revolut Pay and Pay by Bank (Open Banking) work where card-based deposits sometimes do not. The in-app welcome means the headline offer is not a single page; the punter has to look in the app.

LiveScore Bet suits a punter who needs a payment method that is not a debit card. The punter looking for a fixed welcome page will need to open the app.

bet365 — Bet Builder+, Super Boosts and the Largest Betting Catalogue

bet365 holds Commission licence 055148-R-331498-002, with Hillside (UK Sports) ENC as the licence holder. The brand offers Bet Builder+ — combining markets from one event into a single bet, pre-match and in-play — alongside Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. The welcome offer sits inside the app and changes through the year; the running offer is the catalogue of boosts rather than the front-door reward.

The Bet Builder+ mechanic is the operative feature for the punter who builds singles from multiple markets within a single match. The catalogue of daily boosts means the offer is rarely empty, and the bigger the catalogue the more often the punter finds a price that exceeds their own model.

bet365 suits a punter who builds singles from markets and likes a daily price lift. The punter looking for a £40 headline free bet will find smaller sign-ups elsewhere and a much larger boost schedule.

The Calculation: What a Sign-Up Offer Is Worth

The prescribed calculation for this page is the bonus-turnover formula, because the Commission has set a 10x cap on wagering requirements that is the operative constraint on a betting bonus in 2026. The arithmetic belongs to the page rather than to the operator’s terms.

A punter with a £10 bonus subject to a 10x rollover must turn over £100 of qualifying bets — £10 bonus × 10 rollover = £100 turnover. At a stake of £10 per bet, that is 10 qualifying bets. Each bet needs to clear the minimum-odds floor; on a typical football match with a 95% payout share, the expected cost of clearing the £100 is £5 — £100 turnover × 5% margin on the market. The reward is the bonus amount itself, plus any winnings from the qualifying bets once withdrawal is unlocked.

The same £10 bonus under a hypothetical 50x rollover — the old ceiling — needed £500 of turnover, 50 bets at £10 each, and an expected clearing cost of £25 on the same market. The cap is the saving: £100 of turnover instead of £500, and £5 of expected cost instead of £25. On a market with a 6% margin, the saving is £30 instead of £6.

The expected cost is a statistical estimate over many bets under the stated assumptions, not a guarantee for any single bettor. The cap is the rule that brought the estimate down; it is not a rule that makes any single bonus profitable. A punter whose qualifying bets lose more than the margin expects will pay more than £5 to clear a £10 bonus at 10x; a punter whose bets win at better than the market share will pay less. The estimate is the average.

The page states the result as a band with its condition, not as one figure, because the inputs depend on which bookmaker’s bonus the punter is clearing and which market the qualifying bets are placed on. A £10 bonus at 10x on a 95% market costs £5 to clear on average; a £20 bonus at 10x on the same market costs £10 to clear. A £20 bonus at 10x on a 90% market — a market with a higher margin, like a long-shot football handicap — costs £20 to clear. The condition is the margin, and the margin is the variable.

The takeaway. The 10x cap turns a £10 bonus from a £25 clearing proposition into a £5 clearing proposition on a typical market. The Commission did not make bonuses free; it made them cheaper to clear. The punter’s job is to read the bonus terms for the rollover, the minimum odds and the expiry, and to weigh the clearing cost against the headline bonus.

Picking the Right Sign-Up Offer

Three questions decide which of the ten offers above is the right one for a given punter.

The first is what the punter normally bets on. A racing-led account fits Tote or Fitzdares; an acca-led account fits Coral, Unibet, BoyleSports or Sky Bet; an exchange-led account fits Betfair or Smarkets via SBK. A punter who bets mostly on football singles fits Bet600 or bet365. The offer sits inside the betting pattern, not above it.

The second is what the punter values in the running offer. The headline free-bet credit is the first week; the daily boosts, the acca insurance, the Cash Out availability and the Best Odds Guaranteed on racing are the months after. BetVictor’s pitch is the running boost schedule. bet365’s pitch is Bet Builder+ and the Super Boost catalogue. William Hill’s pitch is Best Odds Guaranteed on UK and Irish racing from 8 AM on race day — a feature that lifts the punter’s return on any horse they back after the morning declaration.

The third is the structural fit. Smarkets runs the exchange licence category; the others run the standard bookmaker category. Fitzwilliam Sports caps its membership. Spreadex runs spread betting on the FCA authorisation alongside fixed-odds betting on the Commission licence. The punter whose account sits inside one of these structures is on the right site; the punter who needs a different structure is not.

Verifying a Licence on the Commission’s Public Register

The Commission’s public register is searchable by business name, trading name, domain or account number. A punter who wants to check whether a brand holds a licence types the brand name into the search box, reads the licence category and the licence holder, and confirms the trading name matches the brand. The domain alone proves nothing; licensed operators use .com and .co.uk interchangeably, and unlicensed brands use both too.

The register is the whole test of whether a brand holds a licence. There is no separate “approved bookmaker” list elsewhere; the Commission’s register is the list. A punter who finds a brand on the register has found it; a punter who does not, has not. The register also carries the licence status — whether the licence is active, suspended or revoked — so the punter can tell the difference between a brand that holds a licence and a brand that once held one.

The numbers on this page — 53028 for Hollywoodbets, 400 for Fitzdares, 54779 for Tote, 39576 for BetVictor, 44731 for Bet600, 48760 for Fitzwilliam Sports, 39439 for Betfair, 39173 for Smarkets, 56859 for LiveScore Bet, 55148 for bet365 — are the account numbers to type into the search box. The category on each entry should read “remote general betting standard (real events)” for nine of the ten, and “remote betting intermediary” for Smarkets.

The Promotion Rules in Practice

The 10x cap and the mixed-product ban both landed on 19 January 2026, and both shape the offers on this page. None of the ten welcome offers above is a mixed-product promotion; all ten are sports-only. The cap is the operative constraint on a punter who has been offered bonus cash rather than free bets — a structure more common in casino welcome packages than in sports sign-ups, but a structure that does appear on sportsbook promotions around major tournaments.

The punter’s check on any new offer is threefold. First, whether the offer is a free bet (stake not returned, no rollover) or bonus cash (stake returned, rollover applies). Second, the rollover multiple if it is bonus cash — and whether it exceeds the 10x cap. Third, the minimum-odds floor on the qualifying bet, because a floor of 1.01 makes the qualifying bet a formality while a floor of 2.0 makes it a real bet.

The mixed-product ban closes the door on offers that bundle a sportsbook with a casino, bingo or lottery. A punter who sees a “bet on football to claim free spins” deal on a licensed site is looking at an offer that should not be there; the operator offering it is the one in breach, not the punter.

A Note on the 25% Remote Duty Rate

The Government announced on 26 November 2025 that the remote betting element of General Betting Duty will rise to 25% from 1 April 2027, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Until that date the remote rate stays at 15%, the current rate.

Whether operators pass the duty through to customers in lower odds is not established. Some operators absorb duty and price accordingly; some tighten the margin to compensate. The customer is not charged duty directly — General Betting Duty is the operator’s tax on gross profits — and the punter does not see a duty line on the betting slip. The 25% rate is a margin pressure on the operator, and the question for 2026‘s punter is whether the headline price on the betting slip moves. The honest answer is that the move, if any, will be visible in the odds rather than in the duty line, and the punter will not be told which operator has moved and which has not.

The £10,000 cap on William Hill’s Football Acca Boost sits inside this picture. The boost is a percentage on top of acca winnings, not a margin adjustment, and the duty rate does not change its cap. A punter whose acca winnings before the boost exceed £10,000 sees the boost capped at £10,000; the duty rate sits on top of the operator’s margin, not on top of the boost.

What an Offer Actually Costs in 2026

A £20 qualifying bet at 2.0 to unlock £40 in free bets, the kind Coral and Unibet run, costs the punter a £20 stake at 2.0. On a 95% market the expected loss on the qualifying bet is £1 — £20 × 5% margin. The reward is £40 in free bets, expected value around £28 on the same market. The net expected value is around £27 on a £20 stake over many such claims, before the time cost of running the offer.

A £5 qualifying bet to unlock £30 in free bets, the kind Sky Bet run, costs £5 at minimum odds of 1/1. The expected loss on the qualifying bet is £0.25. The reward is £30 in free bets, expected value around £21. The net expected value is around £20.75 on a £5 stake.

A £10 bet at minimum odds of 3.0 to unlock £60 in free bets, the kind SBK run, costs £10 at 3.0. The expected loss on the qualifying bet is £0.50 on a 95% market. The reward is £60 in free bets, expected value around £42. The net expected value is around £41.50 on a £10 stake.

The numbers are illustrative; they are the page’s own calculation, and they use the prescribed bonus-turnover formula. The punter’s actual experience depends on the market they bet on, the stake they place and the odds they take. The estimates are averages over many such claims, and the page states them as estimates. No single claim is guaranteed to clear at the expected value, and the punter should treat the offer as a marketing device with a measurable cost rather than a free lunch.

The Long View

The Commission’s promotion rules, the identity verification at the till, the £150 vulnerability-check threshold and the GAMSTOP coverage are not the only changes in the last few years, but they are the ones that have moved the offer. A punter who opened an account in 2019 had a different experience: no verification before the first deposit, no GAMSTOP check at sign-up, no cap on bonus wagering, no ban on mixed-product promotions, and an offer that the operator could size however it wished.

A punter opening an account in 2026 sits inside a tighter set of rules, with a Commission register that the punter can check and a bonus cap that holds the operator’s offer down. The offers above are smaller and slower than the 2019 equivalent. They are also more transparent, because the terms page sits behind every offer and the Commission’s rules sit behind every terms page. A punter who has read this far has a better picture of what an offer is worth than a punter who has only the marketing copy.

The next change is the 25% remote duty rate from 1 April 2027. Whether that moves the offer price depends on the operator; the punter will see it in the odds rather than in the duty line, and the punter’s comparison is the way to find the right fit. The ten bookmakers above are the comparison; the rest is the punter’s own bet.

Frequently Asked Questions

How do I use a promo code on a betting site in Great Britain?

Most UK bookmakers have moved from promo codes to opt-in buttons inside the app or on the sign-up page. Open the account, pass identity verification, opt in to the welcome offer, place the first qualifying bet at the minimum odds stated in the terms, and the free bet is credited. The “code” is the opt-in step rather than a string of letters.

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

Ten times the bonus. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x, so a £10 bonus at 50x needed £500 of bets before the cap and no more than £100 after it. Free bets without a rollover do not fall under the cap.

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

Minimum odds is the floor on the qualifying bet — Coral and Unibet set it at 2.0 (1/1) for their sign-ups, BoyleSports and Spreadex at 1/2. Wagering requirement is the number of times the bonus must be bet before winnings can be withdrawn; under the 10x cap, a £10 bonus needs £100 of qualifying bets before withdrawal, where a 50x bonus needed £500.

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

A free bet is a one-shot stake the bookmaker credits; the stake is the operator’s money, not the punter’s, and the operator’s standard rule is to keep it on a win. A £10 free bet at odds of 3.0 returns £30, not £40 — £20 profit rather than £30 — and the £10 stake vanishes once the bet is settled. The expected value of the offer sits below the headline credit because of this rule.

Can a sportsbook offer a casino bonus under the Gambling Commission’s promotion rules?

No. Mixed-product promotions — an offer that requires gambling on two or more product types, such as betting and casino, bingo or lottery — have been banned by the Commission since 19 January 2026. A licensed sportsbook can run a sports-only offer; it cannot bundle it with a casino, bingo or lottery reward. The ban applies to the operator offering it, not to the customer.

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

Search the Commission’s register by trading name, business name, domain or account number. The register lists the licence category, the licence holder and the trading names covered; the domain alone proves nothing because licensed and unlicensed brands both use .com and .co.uk. The numbers on this page — 53028 for Hollywoodbets, 400 for Fitzdares and so on — are the account numbers to type into the search box.
