Every time you log in to a British bookmaker, a small lookup happens before the markets load. Your details are checked against the national self-exclusion register, and a yes or no comes back. Betting sites not on GAMSTOP are simply bookmakers that never make that call, because they hold no licence from the Gambling Commission and have no duty to ask.
We wanted to understand that lookup properly: what data goes in, what the bookmaker is told, where the system goes blind, and what happens to a disputed bet once you are outside it. This guide walks through the plumbing first and the consequences second, and it ends with the licensed options and the tools that close the gaps. We do not name or link to any bookmaker without a British licence.

How does GAMSTOP match your details to a betting account?
GAMSTOP does not issue a card, a code or a device block. It is a register of people, and it works by comparing what you gave the scheme with the details you later type into a bookmaker’s registration form. When you sign up, GAMSTOP asks for your title, first and last name, date of birth, your current address and postcode, any postcodes you have lived at before, and any email addresses and mobile numbers you use now or have used in the past. Your identity is verified during that process, which can involve document checks or knowledge-based questions.
On the bookmaker’s side, the licence condition is simple to state. The operator sends its customer’s details to GAMSTOP and gets back a self-exclusion status. According to the scheme’s privacy policy, the data it receives from operators is hashed and held only as long as the check requires. The bookmaker does not receive your GAMSTOP file, your reasons for registering or your chosen exclusion length; what it needs is the answer to one question, and that is what it gets.
Timing matters. Licensed operators must check when someone tries to register or log in, and they must also run a check across their entire customer list at least once every 24 hours. That second check catches existing accounts belonging to people who registered overnight. GAMSTOP says it generally activates a new self-exclusion within 24 hours, while being clear that it cannot guarantee that window and that the speed on any given site also depends on the operator’s own systems.
| Detail you register | Why it helps the match | What goes wrong if it is missing |
|---|---|---|
| Full name and date of birth | The core identity pair every bookmaker already collects for age verification | A misspelt name or swapped day and month can stop a record lining up |
| Current postcode and address | Separates people with the same name and birthday | An out-of-date address on either side weakens the match |
| Previous postcodes | Covers old accounts opened before a house move | A dormant account registered at a former address may slip through |
| Every email address, old and new | Bookmaker accounts are often keyed to an email | An account on a forgotten address is harder to link |
| Every mobile number, old and new | Many apps use a phone number for sign-up and security codes | Same problem as email, on a different identifier |
What can the register see, and where does its view end?
A national register sounds total, but its reach is defined by licence conditions, and those conditions are written channel by channel. The Commission’s Licence Conditions and Codes of Practice (LCCP) require remote licensees to take part in the national multi-operator scheme under social responsibility code 3.5.5. A different provision, 3.5.6, requires premises-based operators in the betting, arcade, bingo and casino sectors to join multi-operator schemes for their own venues. So the shop on the high street and the app on your phone sit under separate rules and separate registers.
| Channel | Visible to GAMSTOP? | Mechanism that does apply | Where the duty comes from |
|---|---|---|---|
| Licensed bookmaker website or app | Yes | GAMSTOP check at sign-up, login and daily | LCCP SR code 3.5.5 |
| Licensed telephone betting | Yes | GAMSTOP, following the extension to phone betting | Remote licence conditions |
| High street betting shop | No | Gamstop Betting Shops (formerly MOSES), free on 0800 294 2060, covering shops in the area you choose | LCCP SR code 3.5.6 |
| Land-based casino | No | SENSE, the casino sector’s own scheme | LCCP SR code 3.5.6 |
| Sportsbook with no British licence | No | Nothing on the operator’s side; only bank blocks and blocking software | None; the operator is outside the system |
That final row is the entire subject of this page. An offshore bookmaker never sends a query, so the register has nothing to answer. No amount of accurate data on your GAMSTOP account changes that, which is why the blocking tools further down work on a different layer: your payments and your devices.
What must a licensed bookmaker do once you are flagged?
Getting a match is the start of the process at a licensed book. The Commission’s self-exclusion code for remote operators (SR code 3.5.3) sets out what follows, and it is more thorough than most people expect.
- Any account belonging to the self-excluded person must be closed, and money held in it returned.
- Name and details must come off marketing databases, with steps taken to do this within two days.
- The operator must run procedures designed to stop that person getting access to gambling, which is where the login and daily checks come in.
- Customers must be able to self-exclude directly with the operator, both through customer services and through an automated online process.
- An exclusion chosen through GAMSTOP cannot be cut short, and when the term runs out, nothing changes until you ask GAMSTOP to remove it.
GAMSTOP’s privacy policy also explains the tail end of the data lifecycle. Details are kept for the exclusion period you picked, then for a further seven years, and a record that a person was previously excluded is also retained.
Compare the offshore version of the same moment. A sportsbook outside the scheme has no match to act on, no closure duty, no marketing suppression rule and no reason to know that you asked to be kept away. If emails from betting brands keep arriving after you registered, the sender is breaching its licence conditions or never held a British licence to begin with.

Why do punters search for bookmakers outside the scheme?
People type this phrase for a handful of reasons, and they are not all the same kind of reason. Some are complaints about how licensed bookmakers operate. One is a sign that the exclusion is under strain.
Accounts restricted after winning
This is the grievance we hear most from regular punters, and the Commission has measured it. Its data request covering calendar year 2024 found 4.31% of almost 15 million active betting accounts under some form of commercial restriction, and restricted customers were far more likely to be in profit than the wider base. Account closure alone applied to 2.23% of active accounts. The regulator has said it is outside its remit to dictate how operators manage commercial liabilities, and it acknowledged that limiting accounts could nudge some of those customers to unlicensed books. We break the figures down in our guide to UK betting sites.
Checks that feel like friction
Licensed bookmakers verify age and identity before any deposit or bet, a rule in place since 7 May 2019. Financial vulnerability checks against public records start when net deposits reach £150 over a rolling 30 days, and they do not affect your credit file. Since 31 October 2025, new customers are prompted to choose a financial limit before their first deposit. Each is a small delay, and some bettors resent all three.
Promotions that got smaller
Since 19 January 2026, wagering on a UK bonus cannot exceed ten times, and a single offer can no longer tie sports betting to casino play. Offshore sites advertise larger bundles without those limits. The limits exist because the old bundles were hard to clear and easy to misunderstand.
An exclusion that is hard to live with
Some searches come from people already on the register. If that is where you are, the scheme working as intended is part of what makes this difficult, and there is nothing unusual about finding it hard.
What happens to bet settlement when no British regulator is watching?
A casino spin settles when the reels stop. A sports bet settles later, against a result, under a rulebook the bookmaker writes. Between placement and payout, a sportsbook makes a series of decisions: which data source defines the result, how an abandoned or rescheduled event is treated, whether a substitute counts for a goalscorer market, what counts as an obvious pricing error, and whether an account pattern looks irregular enough to void bets. Licensed and unlicensed books both make those calls. What differs is who can review them.
At a UKGC licensee, the terms have to be fair and transparent, the complaints process has published time limits, and the final word on a deadlocked complaint belongs to an independent body. Offshore, every stage of that chain belongs to the operator. Four patterns show up repeatedly in complaints about unlicensed sportsbooks, and each one is a design choice the operator is free to make.
Payment rails add a further layer. Many offshore sportsbooks take cryptocurrency, and a completed blockchain transfer cannot be recalled by a bank. For more on how coin deposits behave, see our page on crypto betting sites.
Integrity is the part almost nobody mentions. Licensed operators feed suspicious betting reports into the Commission’s Sports Betting Intelligence Unit, which works with sports governing bodies and police. A market on a lower-league match offered by a book outside that loop has no such reporting line, so if the event itself is compromised, nobody on the betting side is obliged to raise it.
How does a disputed bet run, stage by stage?
We mapped the same argument, say a goalscorer bet settled as a loser when you believe the player scored, through both systems. The licensed column follows the Commission’s complaints and ADR requirements. The offshore column describes the typical absence of equivalents, since there is no single rulebook to cite.
| Stage | UKGC-licensed bookmaker | Unlicensed sportsbook |
|---|---|---|
| Raising it | Formal complaints process; you must be allowed at least six months from the incident | Live chat or email; time limit set by the operator, if any |
| Acknowledgement | Within 24 hours where the operator runs a 24-hour service | No external standard |
| Operator decision | Overall eight-week timeframe, which can pause if you take more than seven days to supply requested information | Open-ended |
| Escalation | Final response must name the operator’s approved ADR provider; IBAS is widely used | No approved ADR; any named mediator has no British standing |
| Cost to you | ADR is free for the customer | Legal action abroad, usually uneconomic |
| Regulator’s role | Commission can act on systemic failures and licence breaches | Commission can pursue illegal gambling but cannot recover your stake |
Curaçao comes up often here, because many offshore sportsbooks cite it. Its National Ordinance on Games of Chance (LOK) came into force on 24 December 2024, handing licensing to a new Curaçao Gaming Authority, and genuine seals now link to a validation page on cert.cga.cw showing the licensed domain. Those are real improvements for that jurisdiction. A Curaçao licence still gives no permission to serve customers in Great Britain, and it gives a British punter no route to a British adjudicator.

Which UK protections were written with betting in mind?
Much of the offshore pitch talks about UK rules as though a football punter lives under slot machine law. The £5 and £2 per-spin stake caps from 2025 apply to online slots only, and so do the 2.5-second spin rule and the autoplay ban on slots. Bookmakers set maximum stakes per market as a commercial choice. The protections that do reach sports betting are mostly about money, information and fairness.
- Broadcast delay warnings. Remote Technical Standard 15 requires information explaining that “live” pictures are delayed and that others may have more current information, placed on main in-play pages where practicable.
- Free bets and restrictions. Commission guidance says that if you had begun qualifying for a free bet before your account was restricted, the restriction must not stop you getting the offer’s full value.
- Incentive limits. Wagering capped at 10x and no mixed-product offers, both from 19 January 2026.
- No reverse withdrawals. Once you ask for a payout it has to leave; cancelling it to keep betting has been banned since 31 October 2021.
- No credit. Credit cards, and e-wallets loaded from them, have been off limits for gambling since 14 April 2020.
- Funds disclosure. Each licensee must say whether customer balances are not protected, or protected at medium or high level, in an insolvency.
- Limits that stick. Since 31 October 2025, raising a deposit limit needs at least 24 hours of cooling-off plus confirmation, while cutting one takes effect straight away.
We think the licensed route is clearly the safer one for punters, and it still has costs. It would be a strange sort of analysis that hid them.
Plus
- Independent, free adjudication when a settlement is disputed
- Verification done before betting instead of at payout
- Free bet value protected if a restriction lands mid-offer
- Suspicious markets reported into a national integrity unit
- GAMSTOP, limits and time-outs that work across the whole market
Minus
- Winning accounts can be stake-factored or closed on commercial grounds
- Public-record checks at £150 of net deposits in 30 days
- Smaller, simpler promotions under the 10x cap
- Remote betting duty rising from 15% to 25% on 1 April 2027 (UK horseracing stays at 15%), which may thin offers further
- No credit and, in practice, very little crypto
A better price only has value if someone independent can make the bookmaker honour the slip.
How can you confirm a bookmaker’s licence in a couple of minutes?
A licence claim in a website footer is just text. The Commission’s public register is the source of truth, and checking it is quicker than reading a welcome offer.
- Scroll to the footer and note the Gambling Commission account number. A footer that mentions only an overseas authority tells you what you need to know.
- Enter the number or company name on the Commission’s public register.
- Confirm the licence status is active, not suspended, surrendered or revoked.
- Check that the licensed activities include remote betting.
- Look at the list of domains on the record and make sure the exact address in your browser appears there. Cloned sites rely on people skipping this step.
- Open the complaints section of the terms and find the named ADR provider.
- Find the customer funds protection statement.
If you only bet occasionally, that last point may feel academic. It stops being academic if a bookmaker goes into administration holding your balance. Our wider explainer on non Gamstop casinos covers how the same register check works for casino operators.

What actually closes the offshore gap?
Because an unlicensed sportsbook never talks to GAMSTOP, the tools that reach it work elsewhere in the chain: on the payment, or on the device. Layering them gives much wider cover than any one alone.
| Layer | Tool | Intercepts | Cost |
|---|---|---|---|
| Licensed operators | GAMSTOP | Account access at every UKGC-licensed online and phone operator | Free |
| High street | Gamstop Betting Shops | Chosen betting shops in the areas you name | Free |
| Payments | Bank gambling block (Monzo, Starling, Barclays, Lloyds, NatWest and others) | Card transactions coded as gambling, offshore merchants included | Free |
| Devices | BetBlocker | Gambling sites and apps on the phones and computers you install it on | Free |
| Devices | Gamban | Gambling sites and apps across your devices | Paid |
A bank block depends on how a merchant’s card payments are categorised, so it cannot promise to catch every transaction, and it does nothing about crypto bought elsewhere. Device software catches the sites themselves. That is why the two together cover more than either does alone.
Betting sites not on GAMSTOP: questions answered
Does a bookmaker find out why I joined GAMSTOP?
No. The operator sends your details for checking and receives your self-exclusion status. The scheme’s privacy policy describes operator data as hashed and held only for the check, and nothing about your reasons or circumstances is passed back.
I registered this morning. Why could I still log in to a betting app?
GAMSTOP generally activates exclusions within 24 hours but does not guarantee it, and each operator’s systems affect timing. Licensed operators must sweep their full customer lists at least daily, so access should close shortly. If it does not, contact GAMSTOP and the operator.
Should I add old email addresses and phone numbers to my GAMSTOP account?
Yes. Matching relies on details lining up, and the Commission notes that small differences can let a person keep gambling. Adding former addresses, postcodes, emails and mobile numbers strengthens the match with accounts you may have forgotten.
What happens to money left in a betting account when I self-exclude?
Under the Commission’s self-exclusion code, a licensed operator must close the account and return the funds held in it. It must also remove you from its marketing lists.
Does GAMSTOP stop me betting over the counter in a bookmaker’s shop?
No. Shops fall under a separate duty for premises operators. Gamstop Betting Shops, previously called MOSES, lets you exclude from shops in chosen areas through a free call to 0800 294 2060.
Can I take an offshore sportsbook to IBAS?
No. Approved ADR providers handle complaints against operators the Gambling Commission licenses. A bookmaker without that licence sits outside the arrangement, so there is no independent British body to review its decision.
Am I breaking the law by betting with an unlicensed bookmaker?
The offences in the Gambling Act 2005 are aimed at operators: section 33 for providing unlicensed facilities used in Great Britain, and section 330 for advertising unlawful gambling. The practical risk to you is financial, because nobody in Britain can make that operator pay.
How long does a GAMSTOP record stay on file?
For the exclusion period you chose, then a further seven years, according to the scheme’s privacy policy, which also describes keeping a record that someone was previously excluded.
PCZ verdict
Once you look at the machinery, GAMSTOP’s reach is easy to describe: it can only stop bookmakers that ask. Betting sites not on GAMSTOP are defined by never asking, and the same gap removes the complaint deadlines, the adjudicator, the integrity reporting and the funds disclosure that make a disputed slip winnable. The licensed market has genuine faults, with account restrictions the biggest for regular punters. We still think a restricted account at a regulated book is a better position than a full-stake account where the operator is also the judge. If you are excluded, the better move is to strengthen the block with bank and device tools.
