The phrase reads as a search for an offshore workaround. Read as a Gambling Commission question, it lands somewhere else entirely. Since 31 March 2020 online betting in Great Britain has run under a single, mandatory rule: every operator holding a remote licence must check the GAMSTOP register before a customer logs in or signs up. The register is national, the check happens at the door, and the licence that lets a bookmaker take a bet at all is the same licence that binds it to the register. A site outside GAMSTOP within Great Britain is, by definition, an unlicensed site — and an unlicensed site is a choice the player makes on their own, with the consumer protections that come with a Commission licence left at the door.

The pages that follow take that as their starting point. They walk through what GAMSTOP is and how it works in practice; what the Gambling Commission requires of a licensed bookmaker by way of tools, identity checks and dispute resolution; how the ten brands on the shortlist compare against that same rule set; and what a bettor on a site outside the licence framework is giving up. The 10 operators reviewed are all holders of a Gambling Commission remote licence. None is an offshore alternative, and nothing in the article explains how to put GAMSTOP behind you.

Current as of October 30, 2026 against the Gambling Commission’s public register and operator terms.

The real shape of GAMSTOP — what it does, how long it lasts, what removing it costs

What the scheme is, and why a bookmaker licence comes with it

GAMSTOP is a free national self-exclusion service run by The National Online Self Exclusion Scheme Limited, a company registered in England and Wales under company number 10504973 and based in Harrogate. It blocks access to existing accounts and prevents new accounts with online gambling companies licensed in Great Britain; the operators themselves check the register each time a person logs in or signs up. The service costs the user nothing — no fee, no subscription. More than half a million people in the UK are on it.

For the bookmaker, GAMSTOP is not optional. It is a condition of the remote betting licence — licence condition 3.5.1 of the Licence Conditions and Codes of Practice (LCCP) — and has been since 31 March 2020. An online operator that ignored the register at sign-up or login would lose its licence. The check takes a fraction of a second, but the consequence of getting it wrong is the closure of the UK business. The result is an unusually tight bond between “licensed to take bets online from a customer in Great Britain” and “checks GAMSTOP before that customer bets”. A site that breaks the bond is a site that, by virtue of breaking it, no longer holds the licence that lets it serve this market.

How long an exclusion lasts, and what ending one involves

A registrant chooses from three minimum periods — six months, one year or five years. The six-month term is the shortest available; a five-year term can be set to renew automatically. The exclusion does not lift by itself when the minimum period ends. Under auto-renewal a new five-year minimum begins automatically at the close of each five-year term. A registrant who did not pick auto-renewal must contact the GAMSTOP Contact Centre to deactivate the exclusion; after that contact, a 24-hour cooling-off period applies before the exclusion comes off.

Once removed, the protection is not quite finished. Operators continue to be informed for a seven-year period that the person was previously self-excluded, but they are not required to prevent access during that time. The point of the seven-year record is audit, not blocking: a Commission-licensed operator that opens a fresh account for someone who self-excluded recently will be asked why, and the GAMSTOP history is what an inspector reaches for first.

What GAMSTOP covers, and where it stops

The scheme blocks online sites and apps. Betting shops are covered by a separate service, Gamstop Betting Shops — the same restriction takes a different name there because the channel is different. The distinction matters because some of the search traffic that lands on this page comes from people who have self-excluded from a shop on the high street and assume the online register does not apply to them; it does, and the two registers do not currently talk to each other.

GAMSTOP also draws a line at the British coastline. A bookmaker licensed only in Malta, Curaçao or Gibraltar and serving British customers without a Commission licence is outside the register — which is exactly the point that turns “betting sites not on gamstop” from a search for a feature into a search for an entirely different market. That move carries real consequences, and the section on legality below works through them in plain terms.

Fundamentals of licensed betting in Great Britain — the rule set the question skips past

The licence is the whole test

In Great Britain the question of whether a betting site is “on” or “off” GAMSTOP reduces, once the regulation is set out, to a single test. The Commission holds a public register of every operator it has licensed, searchable by business name, trading name, domain or account number. The presence of a brand on that register, holding a remote general betting standard (real events) licence or a remote betting intermediary licence, is the entire answer. The domain tells the reader nothing useful: licensed operators use both .com and .co.uk; the test is the register entry, not the address bar.

A financial spread-betting firm sits under a different regulator. Spreadex, for example, is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting, and its own homepage warns that spread-betting losses can exceed deposits. The point holds more broadly: a name on the financial register does not put a firm on the Commission’s register, and a Commission licence does not cover the spread-betting products the FCA watches.

Identity check, age check, deposit check — the floor under the licence

Every customer at a Commission-licensed online bookmaker has identity verified before the first deposit. Name, address and date of birth are checked, and that check has run since 7 May 2019 — even when the stake is a free bet or a bonus credit. No anonymous play exists at a licensed site, and the verification runs once per customer, not per deposit. Source-of-funds questions at higher spend are part of the same framework under the money-laundering rules; they look intrusive because they are intrusive, and a bookmaker that does not ask them is, in practice, not licensed.

The minimum age is 18, set in the Gambling Act 2005 itself, and identity verification is the lever. A licensed bookmaker that failed the check for an underage customer would lose its licence; an unlicensed one loses nothing except the customer.

Dispute resolution and the route back if a withdrawal stalls

A licensed bookmaker is bound by the LCCP to handle complaints through its own process first, then refer unresolved disputes to a Commission-approved alternative dispute resolution (ADR) body — for betting, that body is currently IBAS (the Independent Betting Adjudication Service). The route costs the customer nothing and binds the operator to the outcome. A customer without that route has the small-claims court, the operator’s home regulator (if any), and the bank chargeback; each of those is slower, narrower and more uncertain than the ADR process a Commission licence brings.

Responsible-gambling tooling the LCCP requires

A licensed bookmaker is not free to leave responsible-gambling tooling to marketing. The LCCP and the Remote Technical Standards (RTS) prescribe what must be in place, and the operator’s own product has to deliver it. The minimum set, in the language the licence uses, runs to:

• Deposit limits that a customer can set, change down immediately and change up only after a confirmation cooling-off period. The first phase of these has applied since 31 October 2025; a second phase has been postponed to 30 September 2026 and whether it is live is not established. The state has set no deposit ceiling; the limit is the customer’s choice.
• Product restrictions — a customer can block themselves from casino, from sports, from a particular sport, from a particular market type. A bettor who knows they chase in-play can lock in-play off.
• Session and time reminders, with the rules around them written into the LCCP and not left to the operator.
• Self-exclusion at the operator level that runs from six months to five years, separately from and in addition to GAMSTOP.
• A financial vulnerability check (LCCP 3.4.4) for any customer whose deposits minus withdrawals exceed £150 in any rolling 30-day window — a public-record check (bankruptcy, county court judgments), not a credit-reference check or an income check. The figure is the trigger, not the threshold for being told to stop; the check is a flag, not a wall.

A “financial risk assessment” — the press’s “affordability check” — is on a separate track. The Commission has announced a staged plan for these (article of 7 July 2026), with no start date set. The published direction is “announced, staged, no start date”, not “in force”. Treating the published direction as law today gets the operator’s licensing position wrong.

Help when a customer needs it, separately from the operator

GamCare runs the National Gambling Helpline; GambleAware funds treatment and education; the NHS runs specialist gambling clinics; Gamblers Anonymous runs mutual-aid meetings. A licensed bookmaker surfaces links to those services in its safer-gambling pages; an unlicensed one does not have to, and most do not.

Legal frame — what the rules say and what an offshore site actually costs

The Act, the licence, and who the law aims at

The Gambling Act 2005 covers Great Britain — England, Scotland and Wales. Northern Ireland sits outside the Act under older law, and a “GB licence” or “Great Britain licence” is the only phrase that maps to the Commission’s register. 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 does not substitute. Sections 33 and 36 of the 2005 Act, as amended, are the hooks: section 33 makes providing facilities without the required licence an offence, with up to 51 weeks’ imprisonment, a fine up to level 5, or both, on summary conviction in England and Wales (six months in Scotland). The offence is on the operator, not the customer — the Gambling Commission’s published position is that no offence aimed at a player who merely bets on an unlicensed site has been identified, and stating otherwise gets the law’s direction wrong.

What an unlicensed site does without a Commission licence

Stating the position requires looking at it from the customer’s side. A customer on an unlicensed site gives up:

• GAMSTOP coverage. The unlicensed site does not see the register, does not check it, and does not block on it.
• Identity-verification rigour. Some unlicensed sites verify for fraud-control reasons; none verify because a Commission licence requires it. The standard is inconsistent and the recourse if the verification fails is inconsistent with it.
• The Commission complaints route. A customer with a complaint about a Commission-licensed bookmaker can complain to the operator, take the answer to IBAS, and on to the Commission if IBAS upholds the customer; that ladder exists because the licence creates it. A customer on an unlicensed site has the operator’s own process, plus whatever the operator’s home regulator offers (often much less), plus a chargeback through the card issuer for card-funded play.
• An approved ADR body. IBAS covers Commission-licensed betting in Great Britain. An unlicensed operator has no obligation to belong to it, and most do not.
• British consumer redress if funds are withheld. Practical recovery on an offshore operator depends on the operator’s home jurisdiction and the customer’s card or bank. The route exists in principle; it is slower, narrower and more uncertain than the Commission’s.
• The bonus cap and the vulnerability check. The 10x cap on wagering requirements, in force since 19 January 2026, applies to Commission-licensed offers and to nothing else. The £150 financial-vulnerability trigger is a Commission condition, not a market standard.

The list reads as a list of protections, which is what it is — each one is something an unlicensed site is under no duty to provide. The absence is the offer. A bettor on an unlicensed site is, for regulatory purposes, on their own.

Enforcement — disruption, not blocking

The Commission does not block unlicensed sites in the same way some countries filter ISPs. The tools are cease-and-desist notices, search-engine referrals, work with domain registrars, hosting providers and payment providers. Court-order DNS blocking powers have been given, or are about to be given, to the Commission; writing that “ISP blocking is in operation” is not what the published record supports. Honest framing: an unlicensed site usually still loads; the route to it is a normal browser session; the loss of protection is what a customer signs up for when they sign up.

What an unlicensed site is not

The honest frame, because the question usually carries it, is that an unlicensed site is not “the safe choice”. A licensed site carries identity checks, deposit limits, GAMSTOP, the 10x bonus cap and the LCCP’s safer-gambling code. An unlicensed site carries none of those and the genuine risk of loss of funds. The reader who prefers anonymity, no verification and bonus terms that the licensed market cannot match is choosing those three things, in that order, with the protections absent rather than the protections broken.

Tax

The bettor pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax, currently 15%; from 1 April 2027 a remote betting rate of 25% applies within it, while remote bets on UK horse racing, in-person betting, pool betting and self-service betting terminal bets stay at 15%. Whether the operator passes the rate change through to prices is not established; never write that the player is charged duty. A professional gambler should ask HMRC or an adviser; that is general information, not tax advice.

Credit cards, identity and what the licensed customer sees at the till

Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered by that ban. The Commission-licensed operator verifies identity before the first deposit, accepts that the customer has self-excluded through GAMSTOP at sign-up, offers deposit limits and product restrictions, and routes disputes through IBAS. None of that runs on a foreign licence.

How the comparison is built, and what each row actually says

What the table compares, and why a column had to go

The comparison table at the foot of this section shows the ten featured brands against three things that matter to the question on this page: the operator’s Gambling Commission licence and the registered legal entity that holds it; what the operator’s own terms say on GAMSTOP, customer verification and self-exclusion; and the brand’s position on safer-gambling tooling. The fourth matter the working draft carried — payment methods — was dropped. Only a handful of the operators publish a payment-method list in their publicly accessible terms, and a column that repeats “see site” down nine rows of ten tells the reader nothing they would not learn by clicking through to the brand. Reading the operator’s own deposit and withdrawal page remains the right move on payment details; the comparison reserves its space for what the public register and the operator’s safer-gambling terms actually expose.

Reading each row

The licence number is the entry on the Commission’s public register as of the snapshot date; the licence holder is the entity that holds the licence (several consumer brands can run under one — Ladbrokes and Coral under LC International, Paddy Power and Betfair under PPB Counterparty Services). The safer-gambling column reflects what each operator’s own UK homepage or app listing states, in their own words, on registration, GAMSTOP and self-exclusion. Where an operator offers something distinctive in this space — Unibet’s Player Profile test, Betfair’s in-app time and deposit controls, Kwiff’s bank-card-based limit prompts — the row says so, in the operator’s own framework, without restating what every other row already shows.

A note on Register entries the reader is cross-checking: a Commission licence is the legal test, not a feature. The Commission’s public register lists several hundred holders of a remote general betting standard (real events) licence; the ten below are a shortlist drawn for this article, not the whole market, and no brand on the list is “the only licensed one”. The same applies offshore: a brand outside the register is unlicensed for this market regardless of any other licence it holds.

What the rows actually agree on, and where one differs

The ten rows above agree on the points that matter for this page. They all check GAMSTOP at sign-up. They all verify identity before the first deposit. They all offer deposit limits, time-outs and self-exclusion at the operator level, and they all surface links to one or more of GamCare, GambleAware and the National Gambling Helpline. None of them is a route around GAMSTOP; each is the same lock, with a slightly different set of windows on the safer-gambling surface.

Where they differ is the brand framing of safer play. Unibet (out of frame on this shortlist — see the operator section below) carries a Player Profile test as a feature alongside the standard tools; Betfair bundles time alerts and deposit controls inside the in-app account menu; BetMGM builds the safer-gambling page around its casino parent and lets the bettor pick between product blocks. None of these distinctions moves the row across the GAMSTOP line. They sit, instead, on top of it.

A note on the limits of the table

Each row is a snapshot — of the Commission’s register and of the operator’s own terms on the date this page was prepared. The register entry does not change quietly, but an operator’s safer-gambling page can, and the offer terms in the App Store listings refresh on a roughly weekly cadence. Cross-checking at the brand’s own safer-gambling page and at the Commission’s register before betting is the move that turns the table from a description into a check.

The ten featured brands

A place in the list is not a licence, a recommendation or a ranking; the same set is presented on this page in this sequence, with the safer-gambling comparison above and the legality section above that, so the reader can read the licence column against the operator’s own framing.

Ladbrokes

Ladbrokes runs under Commission account 54743, with LC International Limited as the licence holder. The brand’s sports-betting app is published by Entain Operations Limited and is rated 4.66 from 101,255 ratings in the GB App Store; that volume of ratings puts it in the front rank of British sports-betting apps on customer feedback alone, and the safer-gambling surface covers the standard set — GAMSTOP at sign-up and login, identity check on first deposit, deposit limits, time-outs and self-exclusion at six months, one year or five years. The wider Entain group also runs Coral under the same licence, which is why the two consumer brands share a single register entry; a customer who self-excludes from Ladbrokes does so through GAMSTOP and is blocked from Coral on the same check. For a reader who wants the established British high-street name with the full safer-gambling surface and is comfortable with the operator’s bonus terms, Ladbrokes is the obvious fit; the verdict for the searcher landed here by the phrase “not on gamstop” is that Ladbrokes is on it, by licence, and that the question above is the one to settle first.

Betfair

Betfair runs as both a sportsbook and a betting exchange under the same Commission licence, account 39439, with PPB Counterparty Services Limited as the holder. The same corporate group runs Paddy Power under that licence, which the register makes plain. The sports-betting app lists in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football inside the app, and the 90 Minute Payout market — features a reader chooses Betfair for and ones that define the product surface. On the safer-gambling side, Betfair applies the standard toolkit: GAMSTOP at sign-up and login, deposit limits, time-outs, product restrictions, self-exclusion, with BeGambleAware, GamCare, the National Gambling Helpline and Gambling Therapy surfaced in the safer-gambling pages. For a bettor who wants the betting exchange and the matched-betting route alongside a sportsbook, Betfair is the brand to weigh; for a reader searching for a route around the register, the reality is that the exchange product requires the same licence and the same GAMSTOP integration as the sportsbook.

BetTom

BetTom is the new name on the Commission register in this comparison: remote account 64959, with Bet Tom Limited as the holder. Its sports welcome offer is structured as a free bet plus a parallel casino offer — a 50% back as a free bet up to £50 alongside a 50% back up to £50 as free slot funds — described in the brand’s own terms with the “full terms apply” line that almost every welcome page carries. The standard safer-gambling suite runs underneath: GAMSTOP at sign-up, identity verification before first deposit, deposit limits, time-outs, self-exclusion, with links to GAMSTOP, GamCare and the National Gambling Helpline. BetTom is a fit for a reader after a smaller brand with the full LCCP toolkit in place; it is not a fit for a bettor whose decision is between BetTom and an offshore alternative, because that is not a comparison the licence terms allow.

William Hill

William Hill runs under Commission account 39225, with WHG (International) Limited as the licence holder. The published deposit and withdrawal terms name the practical floor and ceiling of a debit-card transaction — deposits from £5 to £99,000 per transaction and withdrawals up to £33,000 per transaction, with no fee from William Hill. The brand is one of the longer-established names on the British high street and brings that scale to the safer-gambling surface — deposit limits, time-outs, self-exclusion, GAMSTOP at sign-up and login, identity check on the first deposit. For a reader who weights brand longevity and a wide transactional ceiling against the operator’s bonus terms, William Hill is the read; for a reader assessing the brand against the search for an offshore alternative, the licence conditions that permit William Hill to operate in Great Britain also mandate full participation in the national self-exclusion scheme.

Bet600

Bet600 sits under Commission account 44731, with Tyche Tech Limited as the holder. The brand’s welcome structure rewards activity rather than a single stake: at least five qualifying single bets of £10+ at Evens (2.00) or greater within the first seven days of registration, after which one £10 free bet is credited — a qualification window that puts a five-bet workload on the offer and rewards consistency over stake size. The standard safer-gambling suite applies: deposit limits, time-outs and self-exclusion, with GAMSTOP at sign-up. For a bettor who bets in single-stake units rather than large lump-sum stakes, the qualification format fits the betting pattern; for a reader investigating if the brand sits outside the regulatory framework, the register confirms that Bet600 is fully licensed and integrated with the national self-exclusion system.

DragonBet

DragonBet runs under Commission account 64908, with DragonBet Ltd as the licence holder. The brand’s market menu focuses on Welsh football and rugby, alongside racing, American football, in-play betting and bet-builder markets — a regional specialty that frames the rest of the offering. Safer-gambling tooling follows the LCCP line: GAMSTOP at sign-up, deposit limits, reality checks and self-exclusion, identity check on first deposit. For a reader whose betting menu leans on Welsh sport and who values a UK-focused product surface with the standard safeguards in place, DragonBet is the fit; for a reader who treats “not on gamstop” as a feature request, the same register-bound verdict holds.

BetMGM

BetMGM runs in Great Britain under Commission account 39198, with LeoVegas Gaming PLC as the licence holder. The LeoVegas parent supplies the safer-gambling surface, which is shared across both product verticals — the same deposit limits, time-outs, reality checks, product restrictions and self-exclusion shown on the casino side run on the sportsbook side, with GAMSTOP applied at sign-up. The product positioning is the casino-sportsbook crossover that the LeoVegas group has built around the BetMGM brand. For a reader who treats casino and sports as a single wallet and wants the merged safer-gambling surface to follow them across both, BetMGM UK is the natural fit; for a reader after an offshore route, again, the LeoVegas Gaming PLC licence is what brings BetMGM UK inside the Commission’s register.

Dabble

Dabble runs under Commission account 65677, with Dabble Sports UK Ltd as the licence holder. The brand’s welcome offer rewards a flat first bet rather than a stake ladder: “Bet £10, Get £10 in Free Bets” on a first deposit for new customers, with minimum odds applying, a seven-day free-bet expiry and the stake not returned on a winning free bet. The safer-gambling surface — identity check before first deposit, GAMSTOP at sign-up, deposit limits, time-outs, product restrictions, self-exclusion — runs to the LCCP baseline. For a bettor who wants the welcome structure in a single transaction rather than a multi-bet qualification, Dabble is the fit; for the reader asking the question on this page, the verdict repeats: Dabble’s Commission licence is the route through the register, and the brand does not sit outside the scheme.

bet365

bet365 runs under Commission account 55148, with Hillside (UK Sports) ENC as the licence holder. The brand’s app is described in the UK App Store as the most-downloaded sports-betting app in the UK and is the official global betting partner of the UEFA Champions League — a sponsorship footprint that translates, in product terms, into a deep in-play offering, an extensive Bet Builder, an extensive live-streaming library and a price-boost product on featured events. The standard safer-gambling suite applies: GAMSTOP at sign-up and login, identity check on first deposit, deposit limits, time-outs, product restrictions, self-exclusion. For a reader who weights product depth and live-streaming breadth, bet365 is the obvious choice; for the reader asking whether bet365 sits outside GAMSTOP, the answer is no — the same Commission licence that lets Hillside (UK Sports) ENC run the UK business is the licence that joins the brand to the register at every sign-up and login.

Bet Ahoy

Bet Ahoy runs under Commission account 100094, with Bet Ahoy Ltd as the licence holder. The brand’s welcome offer splits the headline amount across two stakes rather than one: “Bet £10 & Get £10 in Free Bets”, made up of a £5 sports bet and a £5 acca — an offer structure that pays a flat headline into two product-shaped credits. Safer-gambling runs to the LCCP baseline: GAMSTOP at sign-up, identity check before first deposit, deposit limits, time-outs, self-exclusion; the brand is also listed on the GAMSTOP public register of participating operators. For a reader who wants the welcome offer across two product surfaces rather than a single sports free bet, Bet Ahoy is the fit; for the reader after an unlicensed route, the licence is the same as elsewhere on the page — Bet Ahoy Ltd’s Commission account 100094 is what binds the brand to GAMSTOP and the rest of the safer-gambling suite.

What a turn at the betting site actually costs — the arithmetic of margin

Why this page does the calculation

A bettor choosing between two routes wants to know what each one costs per turn, not what the headline offer returns. The marketing answer runs in percentages of the deposit and free-bet credits; the cost answer runs in the margin of the market they actually bet on. The calculation below puts the cost of one turn at a regulated bookmaker in concrete figures, using figures the page already carries on its registration, deposit and bonus pages, so the bettor can compare against the offer.

Inputs and the move

Two inputs and one assumption. A monthly budget of £500 placed once across a single betting decision. The illustrative market is a two-way price (the simplest possible: a coin-flip-shaped line), at decimal odds of 1.90 on each side — quoted in fractional terms as 9/10, the same price in the older British notation. The assumption is that the budget is staked once, in full, on the market, with the remaining £500 in the account the result of the stake being placed. No bonus, no free bet, no cashback.

Calculating this cost per turn is how a bettor separates a headline offer from the actual price of a betting market.

What the market keeps

The decimal price of 1.90 on each side is straightforward to read as a bookmaker’s take. A fair coin at true odds of 1/1 (decimal 2.00) on both outcomes would return the full stake plus stake on either side — but a £100 stake split evenly over a coin at 1.90 / 1.90 returns £95 to the winning side. The £5 the bookmaker keeps across the matched stakes is the operator’s margin on the market. On a single £500 stake the headline loss to the bettor, taken across all outcomes of the market on average, is therefore £25 — the £500 staked times the 5% margin.

Why the result is a band, not a single number

The £25 figure is a statistical estimate, an average over many bets at the same price, not a guaranteed outcome for any single bet. On any given stake, the bettor wins or loses the full decision. The £25 is the cost a bettor pays on average per £500 staked at that line, taken across a long run of bets that look just like it.

Reading the £25 as a “house edge” is the closest analogy to a casino, with the qualifier that the figure assumes a market without a stake-returned bias and assumes the bettor does not withdraw mid-stake. A different price on the same market — 1.85 / 1.85, say, or a market with a 6% margin — would push the band up; a 1.95 / 1.95 line would pull it down. The 1.90 / 1.90 line is a typical example, not a quoted price, and the £25 figure is the example’s result, not the market’s.

What a free bet on top of the £500 costs in addition

A free bet whose stake is not returned costs the bettor nothing in margin on the free bet itself — the winnings come off the bookmaker’s balance, not the bettor’s — but costs whatever the market keeps, exactly as a cash stake does, on the same market. At 1.90 on each side, a £10 free bet returns on average £4.74 in winnings after the 5% margin (£10 free-bet-value × (1.90 − 1) ÷ 1.90 × 0.95). The headline “£10 free bet” sits in the offer; the realised value, on this market, sits at £4.74. The same £10 in cash at 1.90 returns £19 on a win, with the cost per turn scaled accordingly.

What the cost says about the offer structure

The arithmetic above is the floor the page stands on when it reads welcome offers. A “100% bonus” whose turnover carries a 5% market margin is the same offer in pounds and pence once the math is done — the question is only how long the bettor’s £500 budget takes to travel through the offer. Reading offers as a percentage of the deposit while ignoring the margin of the underlying markets misses the real cost — calculating the total margin is how a bettor cuts through the headline, and this analysis provides the real view on what a bonus costs.

Frequently asked questions

Which betting sites are not on gamstop?

Within Great Britain, none. Every online bookmaker holding a Gambling Commission remote licence checks the GAMSTOP register at sign-up and login, and that licence is the requirement for offering online betting to customers in England, Scotland and Wales. A site that does not run the check is, by the same logic, not licensed by the Commission.

Does that cover every betting site licensed in Great Britain?

Yes. The check is a condition of the licence, not a feature of the operator; the operator’s safer-gambling code, the LCCP and the Commission’s published licence conditions all bind it the same way. Since 31 March 2020 the same condition has run across all Commission-licensed online operators, and a licensed bookmaker that did not run the check would lose the licence.

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

The list of things a Commission licence brings — GAMSTOP coverage on sign-up, identity verification, an approved dispute-resolution body via IBAS, British consumer recourse if funds are withheld, the 10x cap on bonus wagering that applies under the LCCP from 19 January 2026, and the £150 financial-vulnerability check trigger from LCCP 3.4.4 — applies because the licence applies. The site without a Commission licence is under no duty to provide any of those, and is not bound by any of the limits they impose.

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

The Commission’s public register is searchable by business name, trading name, domain or account number at the Commission’s own site. A brand is licensed in Great Britain if and only if its name, domain or account number is on that register against a holder of a remote general betting standard (real events) licence or a remote betting intermediary licence. The same register entry is the proof; the domain on its own is not.

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

Every Commission-licensed online bookmaker has to offer deposit limits (changeable down immediately, with a cooling-off period for an increase), product restrictions (block casino, block sports, block a particular market), time and reality checks, and self-exclusion at six months, one year or five years, separately from GAMSTOP itself. Those are minimums, set in the LCCP and the Remote Technical Standards; an operator may add more, and the Commission’s safer-gambling code requires it to surface links to GamCare, GambleAware and the National Gambling Helpline in the safer-gambling pages.
