Betting sites not on GAMSTOP: why the question has no clean answer in 2026

The honest answer to the search starts with the licence, not the list. Every online bookmaker licensed by the Gambling Commission in Great Britain has been part of GAMSTOP since 31 March 2020; there is no licensed UK betting site that sits outside the scheme, and there is no comparison to draw between licensed and unlicensed brands on this page. What a punter can do is read what GAMSTOP is, what the licence costs the operator and passes on to the customer, and what ten leading GB-licensed bookmakers — Ladbrokes, Betfair, BetTom, William Hill, Bet600, DragonBet, BetMGM, Dabble, bet365 and Bet Ahoy — actually deliver on price, markets, payment rails and safer-gambling tools. That is the comparison the page sets out: ten GB-licensed brands, judged on what a £10 stake buys.

What GAMSTOP is and why no licensed site is outside it

GAMSTOP is the national online self-exclusion scheme for Great Britain. It is a free service — no fee is charged to use it — run by The National Online Self Exclusion Scheme Limited, a company registered in England and Wales under company number 10504973 and based in Harrogate. The scheme is not a marketing product; participation is a mandatory condition of the remote betting licence every operator in this country holds, and it has been since 31 March 2020.

To deactivate a GAMSTOP exclusion after the minimum period, the registrant must contact the GAMSTOP Contact Centre, after which a 24-hour cooling-off period applies.

The mechanism is simple and worth understanding before any price is read. When a person registers with GAMSTOP, the scheme adds their name and personal details to a list that licensed operators check each time that person tries to log in or open a new account. Existing accounts are blocked and new ones refused, across every online gambling company that holds a GB remote licence. Betting shops are covered by a separate service, GAMSTOP Betting Shops — the online register does not reach them. GAMSTOP itself reports that over half a million people in the UK are registered with the scheme.

A registrant chooses one of four minimum exclusion periods: six months, one year, five years, or five years with auto-renewal. The six-month term is the shortest available. Where auto-renewal is set, a fresh five-year minimum period begins automatically at the end of each five-year term, and the exclusion does not end without action by the person who registered it. To deactivate the exclusion after the minimum period, the registrant has to contact the GAMSTOP Contact Centre, after which a 24-hour cooling-off period runs before any operator is told to lift the block. Once the exclusion is lifted, operators continue to be told for a further seven years that the person was previously self-excluded — they are not required to keep the block in place during that seven-year window, but the marker stays on the customer’s record.

The scheme is built around the licence. A bookmaker that did not take part would not hold a remote operating licence, and a bookmaker offering remote facilities to customers in Great Britain without that licence commits an offence under section 33 of the Gambling Act 2005 (as amended by the Gambling (Licensing and Advertising) Act 2014). The offence sits with the operator, not with the customer: no offence aimed at a punter who places a bet was found in the statute. What the punter loses on an unlicensed site is the architecture around the bet — no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if a withdrawal is held, no cap on wagering requirements, no financial vulnerability check at the £150 deposit-net-of-withdrawals threshold — not a piece of criminal liability for betting. Enforcement against the unlicensed operator runs through cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and court-order DNS blocking powers the Commission has been given or is about to receive. There is no live ISP block to point to.

This page does not list unlicensed brands and does not describe how to register with a bookmaker that does not hold a Commission licence. Every brand below is licensed; every brand below is therefore part of GAMSTOP.

What the Gambling Commission licence actually costs the punter

The licence is not free. It comes with a stack of obligations that change the betting experience, and a punter who does not understand them is paying for them without noticing. Three of them matter most.

Kalooki Sportsbook is operated by Kalooki Sports Book Ltd (company number 12938274), licensed by the Gambling Commission under account number 57730, and is a GAMSTOP member.

Identity verification before the first deposit is the first cost. Since 7 May 2019, every licensed remote bookmaker has had to verify a customer’s name, address and date of birth before that customer could deposit or gamble — including placing a qualifying bet with a free bet or bonus. The check runs against public records and credit-reference data, and the customer cannot keep an account anonymous. A book that is happy to take a deposit from an unverified customer is, by definition, not a licensed book.

The £150 vulnerability check is the second cost. Since 28 February 2025, a licensed remote operator has to run a public-record financial vulnerability check on any customer whose deposits minus withdrawals cross £150 in a rolling 30 days. A public-record check pulls court judgments, bankruptcies and similar markers from open registers; it is not an income check and it is not a credit-reference search. The check is built into the product the customer uses, not offered as a separate opt-in.

The 10x bonus cap is the third. Since 19 January 2026, wagering requirements on bonuses at GB-licensed operators are capped at 10x the bonus amount: a £10 bonus can ask for no more than £100 of qualifying bets before withdrawal. Mixed-product promotions — an offer that requires gambling across two or more product types, for example “bet on football to get free spins” — are banned entirely. The cap binds the welcome offer, the reload and the seasonal promotion alike, and it binds a £50 free bet as firmly as a £5 one. A licensed book that advertised 50x wagering in February 2026 would be advertising something it could not legally offer in April 2026.

On the other side of the ledger the licence gives the punter what the offshore book cannot. Real dispute resolution through an ADR body the Commission has approved. Source-of-funds questions that escalate at higher spend under the money-laundering rules. Deposit limits, time-outs, product restrictions and self-exclusion at the operator level on top of GAMSTOP itself. And the General Betting Duty, a 15% tax on the operator’s gross profits from remote betting (rising to 25% from 1 April 2027 on the remote rate, with UK horse racing, pool betting and in-person bets staying at 15%) — the operator pays it, the punter does not, and there is no tax on betting winnings in Great Britain for the individual customer.

What the customer gives up for that protection

Three things, and they are not small. First, the speed of sign-up. A licensed book that opens an account in under three minutes has skipped a step the regulator requires, and an unlicensed book has skipped every step. Second, the freedom to bet on credit. Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet top-ups; debit cards and bank transfers are not covered by the ban. Third, the freedom to bet in a market the operator has chosen to restrict — for example, a customer whose vulnerability check flags a marker may find their maximum stake cut or their access to certain markets paused. Each of these is a thing the licence does, and none of them is negotiable at a licensed book.

The ten-bookmaker comparison: what each licence actually buys

The table below sets out the ten brands reviewed on this page, with the Gambling Commission account number each carries, the licence holder that runs the remote site, and what the operator’s own published terms state on the subject the page needs to read. The licence holder is the regulated entity; the brand name is the trading name. Several brands run under the same licence holder in the GB market, but each of the ten below is a distinct trading name on the Commission’s register.

Brand Licence holder Commission account What the operator’s own terms state
Ladbrokes LC International Limited 54743 App published by Entain Operations Limited, rated 4.66 from 101,255 GB App Store ratings

The columns the table does not carry are deliberate. There is no margin column, because a margin is a property of a market and an event on a snapshot date — Ladbrokes’ overround on a 1X2 Premier League match on a Tuesday afternoon in November is not the same number as Betfair’s overround on the same match at the same time, and the table’s job is to compare the brands, not the prices. There is no payout-time column, because no consistent published figure across all ten was found. There is no in-play depth column, because in-play depth is a per-event property of an in-play console, and listing it as a brand property would misrepresent what the regulator licenses. Where a brand is named and one of those subjects matters, the operator write-up below carries what research carries — no more, no less.

How to read the welcome offers without being sold to

A welcome offer is a marketing contract written to look like a gift. Reading it as a contract is the punter’s first line of defence, and the four figures below are the four the punter needs before the bonus button is pressed. They appear on every brand above; the table is just a way to set them side by side.

The stake-not-returned flag is the first. A free bet whose stake is paid back with the winnings is worth its face value; a free bet whose stake is not paid back is worth less, and the gap is widest at the short prices the wallet offers love. Dabble’s £10 free bet, with a 7-day expiry and the stake not returned, is the shape of most GB-licensed welcome offers in 2026; it is a real offer, not the marketing word “free” suggests, and the punter who treats it as £10 of risk-free money has not read the small print.

The minimum qualifying price is the second. Bet600 asks for five single bets of £10 or more at minimum price 2.00 (Evens in fractional odds, the British punter’s “evens”) within seven days of registration; the qualifying spend is £50, and only bets at 2.00 or longer count. A punter who drops three £10 singles at 1.50 has not qualified, has burned £30 of stake, and is owed no free bet.

The wagering multiple is the fourth, and from 19 January 2026 it is capped at 10x across every licensed book. A £10 bonus at 10x needs £100 of qualifying bets before withdrawal; a £50 bonus at 10x needs £500. There is no licensed welcome offer in 2026 that asks for more.

The product-split ban is the third. Since 19 January 2026 a licensed book cannot make a free bet on football conditional on opening a casino account, or hand out free spins to a punter who only deposited to bet on the horses. BetTom’s offer — 50% back as a free bet up to £50 on sports, with matching 50% back as free slot funds up to £50 for casino — looks like a mixed-product offer at first reading. It is not: the two halves are independent, each capped at £50, and the casino half is opt-in for customers who want casino as well as sports. A licensed book that bundled the two into a single qualifying condition would be advertising something the regulator does not allow.

What an offer like this actually costs the punter

The page’s calculation sets out what a representative welcome bonus costs the punter in expected terms, not in headline terms. The arithmetic is illustrative and uses round numbers; it is not a price printed by any operator and it is not a forecast of what the punter will actually lose.

Take a turnover of £500 — an illustrative monthly budget for a small-stake punter. Great Britain has no state-set deposit or loss ceiling for betting, so the £500 is the punter’s own ceiling, not a regulator’s. The punter stakes the £500 once through a single two-way market at decimal odds 1.90 (fractional 9/10, the British “9-to-10” against), the kind of even-money line an exchange or a sharp book posts on a coin-toss favourite.

On a market at 1.90 / 1.90 the payout share — the fraction of every pound staked that the market returns to winning punters in the long run — is 1 ÷ (1 / 1.90 + 1 / 1.90) = 1 ÷ 1.0526… = 0.95, or 95%. The bookmaker’s margin is the remainder, 5% of every pound staked. Over a £500 turnover the expected cost is £500 × 0.05 = £25. The expected cost is a statistical average across many bets at the same price; it is not a loss a punter can expect on any individual bet, and it does not include the bonus, which the £500 turnover has already covered.

The band around the figure comes from the assumption. The 5% margin assumes an even two-way market with no juice on either side; most real markets the punter meets are three-way (1X2 on football), wider on the underdog, and carry more margin than the two-way example. At a 6% margin — typical for an English Premier League 1X2 — the same £500 turnover costs £30. At 8% — closer to what a small-market outright or an in-play handicap carries — the cost is £40. The honest band, given a typical mix of markets a small-stake punter actually plays, is £25 to £40 of expected cost on a £500 monthly turnover, before any bonus is factored in. None of this is what the punter will lose in a single bad week; it is what the bookmaker’s pricing takes, on average, from a punter who plays at the same stakes all month.

The welcome bonus changes the picture only at the margin. A 10x wagering requirement on a £10 bonus is £100 of qualifying bets, and at a 5% margin the expected cost of clearing it is £5; at 6% margin, £6. The bonus pays back roughly £4 to £5 of expected value to the punter in fair market conditions, before the operator’s own promotional weighting on eligible markets is read. A punter who chases a £50 bonus at 10x is paying £25 to clear it on average at a 5% margin, and the bonus is worth closer to £20 of expected value; the gap is the operator’s edge on the clearing volume.

The ten brands, one by one

Ladbrokes — the high-street giant running on Entain rails

Ladbrokes’ remote site runs under Gambling Commission account 54743, held by LC International Limited; the app is published by Entain Operations Limited, and the same licence covers Coral, so the two trading names share a regulated entity. The GB App Store carries the app with 101,255 ratings and an average of 4.66, the highest rating count of any book in this comparison. Ladbrokes carries the categories the rest of the licensed market carries — remote general betting standard (real events) and remote betting intermediary, the latter covering its exchange-style products and shared with the rest of the Entain stable.

The brand’s strength is depth of market and the rails that come with it: in-play, acca insurance on selected football leagues, best odds guaranteed on UK and Irish racing, and a single-wallet product that lets a customer move between sportsbook, exchange, casino and bingo without a second account. The brand’s weakness is the welcome offer, which is rarely the headline number on the page — the smaller-stake, lower-wagering shape most GB-licensed books now run, rather than the eye-catching percentage Ladbrokes used to lead with.

For the punter who wants one wallet across sports, exchange and casino under a Commission licence with a million-strong app rating, Ladbrokes is the brand the comparison keeps coming back to. For the punter chasing the headline bonus number, the table above shows where to look first.

Betfair — the exchange-shaped sportsbook

Betfair’s sportsbook runs under Commission account 39439, held by PPB Counterparty Services Limited — the same licence that covers Paddy Power, so the two trading names again share a regulated entity. The app ships in-play betting, a Bet Builder, free live streaming of UK and Irish horse racing and selected football inside the app, and the 90 Minute Payout market that refunds stakes on football matches voided after kick-off. The exchange itself runs on a separate betting intermediary licence under the same holder.

What separates Betfair from a pure sportsbook is the exchange underneath, and the price that comes with it: on a mainstream football match the exchange price is often sharper than the sportsbook price, and the punter who knows how to lay as well as back has a second market on the same event. The downside is the welcome offer, which competes less on headline number than on free bet quality; the Bet Builder and 90 Minute Payout markets are the durable differentiators.

For a punter who wants exchange access and a sportsbook on the same licence, Betfair is the closest thing in the GB market to both products under one Commission account.

BetTom — the smaller-stake welcome with a casino tail

BetTom runs under Commission account 64959, held by Bet Tom Limited — its own licence holder rather than a shared one. The published welcome offer is the most distinctive on this page: 50% back as a free bet up to £50 on sports, paired with 50% back as free slot funds up to £50 for casino. The two halves are independent and each capped at £50; a customer who wants only the sportsbook side qualifies for the sportsbook half without taking the casino product, and a customer who wants both qualifies for both. The casino half falls outside the scope of a sports betting comparison, but it is named because it is part of the same published offer and a punter reading the small print will see it.

The welcome shape is the right one for a punter who plays small. A £50 deposit on the sports side qualifies for a £25 free bet on a £100 first bet, and the 10x wagering cap means the clearing volume is £250 at most on the sportsbook half — small enough to clear without stretching into markets the punter would not otherwise play.

For the punter who bets £10 to £50 a week and wants the welcome offer to fit that stake size rather than stretch it, BetTom is the cleanest match in the table.

William Hill — the deep-market book with the published payment rails

William Hill runs under Commission account 39225, held by WHG (International) Limited. The published payment rails are the clearest on this page: debit card deposit and withdrawal from £5, with a maximum deposit of £99,000 per transaction, a maximum withdrawal of £33,000 per transaction, and no debit card fee charged by William Hill. The same rails apply across the brand’s other products, and the absence of a fee on the standard payment method is the kind of small print that disappears when a punter is choosing a book for the welcome offer and resurfaces the first time a withdrawal is taken.

The brand’s deeper position is in horse racing — best odds guaranteed, extra places on the major festivals, ante-post markets that price up weeks ahead — and in the high-street name a long-time British punter recognises. The weak point is the welcome offer, which sits in the middle of the licensed pack rather than at either end.

For a punter who values a published, fee-free debit card rail above the headline bonus, William Hill is the brand that names the price.

Bet600 — the qualifying-bet welcome

Bet600 runs under Commission account 44731, held by Tyche Tech Limited. The welcome offer is the most rule-shaped on this page: at least five qualifying single bets of £10 or more at minimum price 2.00 within the first seven days of registration, after which one £10 free bet is credited. The shape rewards a punter who plays five singles a week at evens or longer; it penalises a punter who plays one larger accumulator, who would not qualify regardless of total stake, and it penalises a punter who plays below evens, whose singles do not count.

The brand sits in the newer-licensed segment of the GB market — Commission account 44731 is not the longest-established number on the register — and the welcome offer is the clearest signal of which customer segment it wants: the small-stake, multi-bet punter rather than the casual once-a-week punter. For a punter who already plays five singles a week at evens or longer, the £10 free bet is a clean reward; for a punter who plays one accumulator on a Saturday, the offer is not built for them.

DragonBet — the Welsh markets book

DragonBet runs under Commission account 64908, held by DragonBet Ltd. The brand’s published differentiator is its Welsh markets — Welsh football leagues, Welsh rugby, and the racing and American football that travel alongside — plus in-play and a bet builder. The brand is its own licence holder rather than a trading name on a larger group’s licence, which is the structure the GB market tends to favour for sportsbooks that want a regional identity rather than a national one.

For a punter who bets on the JD Cymru Premier or on Welsh rugby above the international level, DragonBet is one of the few GB-licensed books that prices those markets at any length; for a punter who bets only on the Premier League and the Champions League, the brand’s coverage is standard and its welcome offer does not stand out.

BetMGM UK — the LeoVegas-run US-facing brand

BetMGM UK runs under Commission account 39198, held by LeoVegas Gaming PLC, the same Commission account that sits behind the LeoVegas brand. The app is published by LeoVegas Gaming p.l.c. and trades as BetMGM UK. The brand carries the US-facing name into the GB market on a European-licensed operator’s Commission account, and the welcome offer runs through the same promotional structure as the rest of the LeoVegas UK family.

For a punter who already has a LeoVegas account or who plays casino and sports on the same wallet, BetMGM UK is the sportsbook on the same licence; for a punter who wants a sportsbook-only product, the casino weight inside the brand is part of what the £10 stake is buying.

Dabble — the social-shaped sportsbook

Dabble runs under Commission account 65677, held by Dabble Sports UK Ltd. The welcome offer is the simplest on this page: Bet £10, Get £10 in Free Bets on the first deposit, with minimum odds applying, a seven-day free bet expiry and the stake not returned. The shape is the standard GB-licensed welcome in 2026: a £10 qualifying bet at the minimum price the operator sets, a £10 free bet on the same terms, and the punter who treats the free bet as a second £10 stake is reading the contract right.

Dabble’s product differentiator is its social shape — the in-app feed where customers follow other punters’ bets, copy them, and comment — and that is a feature the rest of the licensed sportsbook market has not built out at the same depth. The gamble is regulatory: the social feed has to keep inside the Commission’s marketing and safer-gambling rules, and the brand is one of the newer licence holders on the register.

For a punter who likes the social feed as a tipping tool, Dabble is the cleanest licensed fit; for a punter who bets alone and wants the deepest market, the social feed is a feature the punter pays for in interface complexity and does not use.

bet365 — the volume leader

bet365 runs under Commission account 55148, held by Hillside (UK Sports) ENC. The app is the most-downloaded sports betting app in the UK and the brand is the official global betting partner of the UEFA Champions League — the partnership is a marketing contract, not a regulatory one, but it is the cleanest signal of which competitions the brand prices at depth. In-play, the bet builder, live streaming on a deep roster of events, and the early payout markets are all part of the standard product.

The weakness is the welcome offer, which rarely leads the table and is best read as an entry point into a product the punter stays for rather than a one-off bonus. When pricing the Premier League, the Champions League, the Championship and the European leagues, bet365 sets the volume benchmark, making it a reliable utility for the serious football bettor.

Bet Ahoy — the small acca-shaped welcome

Bet Ahoy runs under Commission account 100094, held by Bet Ahoy Ltd. The welcome offer is Bet £10 & Get £10 in Free Bets, made up of a £5 sports bet and a £5 acca. The split is unusual: half the free bet is a single, half is an accumulator, and the punter who wants to use both halves on singles has to forfeit the acca half. Commission account 100094 is one of the higher numbers on this page, and the brand is among the more recent GB-licensed entrants.

For a punter who plays a Saturday accumulator and wants the welcome offer shaped to that habit, Bet Ahoy is the closest match in the table; for a punter who plays singles, the acca half is a feature the punter does not use.

How to check a bookmaker’s licence in sixty seconds

The Gambling Commission’s public register is the test. It can be searched by business name, trading name, domain or Commission account number, and it lists every operating licence the Commission has issued. A book whose name appears on the register with a current status is licensed; a book whose name does not appear is not. A domain is not a test — a licensed book may run on .com or .co.uk, and an unlicensed book may run on either.

The ten brands above all sit on the register. The account numbers in the table are the search terms. Where a brand is reviewed here and not on the register, the page does not review it.

The safer-gambling tools a licensed book has to offer

The licence binds the operator on safer-gambling tools as firmly as it binds the operator on identity verification. The punter’s toolset, at every GB-licensed book, includes at least the following.

Deposit limits on a fixed time frame — daily, weekly or monthly — set by the customer and changeable only with a cooling-off period. The Commission’s Remote Technical Standards require this, and the first changes have applied since 31 October 2025; a second phase was postponed to 30 September 2026 and whether it is live at the time of reading is not established. The deposit limit is the customer’s setting, not the regulator’s; Great Britain has no state-set ceiling.

Time-outs and self-exclusion at the operator level, separate from GAMSTOP and shorter in duration — a 24-hour cool-off, a one-week break, a one-month break. GAMSTOP is the multi-operator exclusion with the six-month, one-year and five-year periods; the operator-level tools are the same shape at smaller scale.

Product restrictions, where the operator narrows what the customer can bet on — for example, excluding casino for a customer who has asked to bet on sports only. Unibet, on the brand’s UK homepage, lists deposit limits, a Player Profile test, product restrictions and self-exclusion alongside live chat support and links to BeGambleAware, GamCare, GAMSTOP, Gambling Therapy and the BGC; that set is the shape every other licensed book offers, with the exact same regulator-facing requirement behind it.

The £150 financial vulnerability check, since 28 February 2025, on a rolling 30-day basis — a public-record check for court judgments and bankruptcies. A higher spend at a single book, or across the punter’s bookmaker accounts, can trigger an affordability conversation; the published plan for fuller financial risk assessments was announced in stages on 7 July 2026 with no start date, and the punter who reads about “affordability checks” in the press is reading about a set of checks that are partly in force and partly announced.

Help lines, signposted inside every licensed product: GamCare’s National Gambling Helpline, GambleAware, the NHS gambling clinics network, Gamblers Anonymous. A licensed book that does not signpost these is breaching its social responsibility code; a licensed book that does is meeting the floor.

What the customer pays for the protection

Three figures, all from the licence regime, and all of them part of the £10 stake the punter lays down.

The verification cost is the first. A licensed book pays the KYC and ongoing monitoring fees that come with a regulated customer base, and the punter pays for it through the operator’s margin — built into every price on the site. The cost is invisible per bet and visible across the punter’s annualised turnover, and it is the reason a licensed book’s headline price on a Premier League match is rarely the sharpest price the market posts.

The £150 check is the second. A licensed book has to run a public-record check at the threshold and staff a team to handle the cases the check flags, and the staff cost is built into the same margin. For the punter, the practical effect is a one-off pause the first time the threshold is crossed and an affordability conversation at higher spend.

The 10x bonus cap is the third. A licensed book that wanted to advertise 50x wagering in 2026 would have to do so without a Commission licence. The cap is the price the punter pays for the regulator’s view that a bonus at 50x is closer to a loan than to a gift.

On the other side, the punter pays no tax on betting winnings in Great Britain; General Betting Duty is the operator’s tax on gross profits, and it does not pass through to the customer. A professional gambler is a different case and should ask HMRC or an adviser.

What the customer loses by going offshore

The list is the inverse of the protection list. No GAMSTOP coverage on the same site — a punter who has self-excluded and bets on an offshore book has self-excluded from the GB-licensed market and not from the offshore one. No Commission complaints route and no approved ADR body — the punter’s dispute runs through the offshore operator’s own terms, in whatever jurisdiction the operator is based. No British consumer redress if funds are withheld — the punter’s only route is the offshore operator’s own dispute process and the regulator of the country the operator is based in. No 10x bonus cap and no £150 vulnerability check — the offshore book sets its own terms, and the punter cannot rely on the GB cap as a floor.

The page does not list offshore brands and does not describe how to register with one. A punter who has self-excluded through GAMSTOP and is looking for an operator outside the scheme is looking for something the GB-licensed market does not provide, and the safer route is to extend the GAMSTOP period — five years with auto-renewal is the longest — or to use the operator-level time-out and product-restriction tools inside the licensed market.

What the customer should read before the bonus button

The small print on every welcome offer above is the same shape, and the punter who reads it once reads it for every brand on the page. The four numbers are the minimum qualifying deposit, the minimum qualifying price, the wagering multiple, and the free bet expiry; the four flags are the stake-not-returned flag, the eligible-markets flag, the payment-method flag, and the identity-verification flag.

A £10 free bet on Dabble with a seven-day expiry and the stake not returned is worth, at a 5% margin market, £4 to £4.05 of expected value; a £10 free bet on Bet Ahoy split into a £5 single and a £5 acca is worth less, because the acca half carries the higher margin of an accumulator market. The headline number on the welcome offer is the marketing number; the small print is the contract, and the punter who reads the contract before the bonus button has already done the comparison the page exists to make.

Frequently asked questions

Are there betting sites not on GAMSTOP?

No online bookmaker licensed by the Gambling Commission in Great Britain is outside GAMSTOP, and participation has been a mandatory licence condition for remote operators since 31 March 2020. A book that is licensed in Great Britain is part of the scheme. A book that is not licensed in Great Britain commits an offence under section 33 of the Gambling Act 2005 in offering those facilities to GB customers, and the page does not list such brands. The honest answer is that the comparison on this page is between licensed brands, all of which are GAMSTOP members, and the only alternative is the unlicensed market, which the regulator does not allow.

What betting sites are not on GAMSTOP?

No GB-licensed betting site. The Commission requires participation by every remote operator it licenses, and the register on the Commission’s website lists every brand by account number. Ten of them are reviewed above; there are several hundred on the register, and every one of them blocks a GAMSTOP-registered customer at login and at sign-up. A brand that markets itself as “not on GAMSTOP” is marketing its unlicensed status, and the punter should check the Commission’s register before depositing.

Does GAMSTOP cover every betting site licensed in Great Britain?

Yes. The scheme is a mandatory licence condition for remote betting operators, in force since 31 March 2020, and the Commission’s public register does not list an online bookmaker that is exempt. The check runs at login and at sign-up for every licensed brand, so a customer who registers with GAMSTOP is blocked across every licensed brand at once and refused at every new one. Betting shops are covered by a separate scheme, GAMSTOP Betting Shops, and the online register does not reach them.

What does a player lose by betting on a site without a Gambling Commission licence?

The list is the inverse of the protection list. No GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if a withdrawal is held, no 10x bonus cap, no £150 vulnerability check, no source-of-funds escalation under the money-laundering rules. The punter on an unlicensed site is betting under the operator’s own terms, in whatever jurisdiction the operator is based, and the recovery routes are limited to that operator’s own dispute process. The operator commits an offence under section 33 of the Gambling Act 2005 by offering those facilities; no offence aimed at a customer who places a bet was found in the statute, and the page does not say betting on an unlicensed site is illegal.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register can be searched by business name, trading name, domain or Commission account number. Every brand reviewed on this page is listed there; the account numbers in the comparison table above are the search terms. A current status on the register is the test; a domain is not, because a licensed book may run on .com or .co.uk, and the absence of a .co.uk is not, on its own, evidence of anything.

Which tools for controlling play does a licensed bookmaker have to offer?

Every GB-licensed bookmaker has to offer deposit limits on a fixed time frame, time-outs and self-exclusion at the operator level, product restrictions, and links to GamCare, GambleAware, the NHS gambling clinics and Gamblers Anonymous. Since 28 February 2025, a public-record financial vulnerability check runs at the £150 deposits-minus-withdrawals threshold in a rolling 30 days. GAMSTOP sits above all of these as the multi-operator exclusion, with the six-month, one-year, five-year and five-year auto-renewal periods. The exact set of tools each operator offers is published on its safer-gambling page; Unibet’s published set — deposit limits, a Player Profile test, product restrictions, self-exclusion, live chat support and links to BeGambleAware, GamCare, GAMSTOP, Gambling Therapy and the BGC — is the shape every other licensed book offers.
