How GamStop Works: UK Gambling Self-Exclusion Explained

How GamStop works and how to self-exclude from gambling (UK)

When gambling no longer feels like a choice, self-exclusion is a practical and effective way to regain some control. For anyone gambling online in Great Britain, GamStop is the tool that makes this possible. A single registration keeps you out of every gambling website and app licensed in the UK-quick, free, and straightforward.

Here's what this guide covers: how GamStop operates, what it does and doesn't block, how to sign up, and what to expect when your chosen exclusion period finishes. It also tackles the gaps GamStop leaves-especially sites licensed outside the UK-and the safest ways to deal with them.

Self-exclusion isn't a last resort or a confession. It's a sensible tool, best used as an early step-often in combination with lighter-touch safeguards such as deposit limits or time-outs.

What GamStop is, and who runs it

GamStop is Great Britain's national online self-exclusion scheme. Sign up once and you're blocked from opening or using accounts with any online gambling operator licensed in England, Scotland, or Wales, for a period you choose.

The scheme is run by GamStop, the trading name of The National Online Self-Exclusion Scheme Limited-a not-for-profit company, independent from the gambling companies it oversees. The service is free and has been active since 2018.

For licensed operators, joining GamStop isn't optional. Since 31 March 2020, it's been a licence requirement for every online gambling company, with the Gambling Commission suspending any firm that failed to comply. That's why a single registration covers the entire licensed market, rather than requiring a site-by-site approach.

How to register, and how quickly it starts

Registration is done through the GamStop website and typically takes about five minutes. You'll need to provide your name, date of birth, email address, postcode, and mobile number. Adding extra emails or addresses helps ensure that all your accounts are matched correctly. Occasionally, you may be asked to verify your identity with official documents.

After submitting your details, GamStop shares them with all participating operators, who check at both login and sign-up. The block can take up to 24 hours to kick in fully, but many operators act faster. If you're already logged in when your registration completes, expect to be logged out shortly after.

Registering won't automatically return any money left in your gambling accounts. To reclaim any remaining balance, contact customer support for each operator or try logging in until you hit the block-usually, your funds are then refunded to your payment method.

What GamStop blocks, including marketing

GamStop blocks both use of existing accounts and the creation of new ones. Since operators check the database at every login and registration, it's not possible to just sign up again elsewhere within the licensed market.

It should also put a stop to the marketing. Once registered, operators must remove you from their direct marketing lists, so promotional emails and texts from licensed gambling firms ought to disappear. If you still receive them from a licensed operator, it's usually a compliance issue worth reporting, rather than a problem on your end.

How long it lasts, and how to choose

You choose the length when registering: six months, one year, five years, or five years with automatic renewal. The auto-renewal option-introduced at the end of 2024-has quickly become the most popular long-term choice.

You can extend an exclusion while it's active, but you can't shorten it. If in doubt, err on the side of caution and choose a longer block-you can reassess when it ends. Many treatment providers recommend at least a year away to break an entrenched habit, and six months is the minimum period on offer.

Can you cancel it early, and what happens when it ends

No-GamStop cannot be undone or cut short before your chosen period ends. There are no exceptions for a change of heart, and that's by design: it's the friction that helps protect you if the urge to gamble returns.

When your chosen period comes to an end, the block doesn't switch itself off. To regain access, you'll need to contact GamStop, confirm your identity, and wait through a mandatory 24-hour cooling-off period before any licensed operator will let you back in. If you do nothing, the exclusion quietly stays in place-continuing to protect you. For those who picked auto-renewal, it extends automatically with no action required.

GamStop versus self-excluding with one casino

Most casinos allow you to self-exclude from just that one site, usually via the responsible gambling section of your account. It's useful if one operator is causing issues, but it only covers their brand-nothing prevents you from opening accounts elsewhere.

GamStop casts a wider net. One request covers every GB-licensed online operator at once, even those you've never registered with. If your gambling spreads across several sites, or you're concerned about signing up to new ones, GamStop is the more robust solution. There's nothing to stop you doing both.

What GamStop doesn't cover

GamStop is built for licensed online gambling in the UK, so there are three notable exceptions.

It doesn't cover land-based venues-physical casinos are covered by the SENSE scheme, while betting shops have their own multi-operator exclusion arrangements. GamStop also doesn't include the National Lottery or its products.

The biggest gap is with gambling sites licensed outside the UK. GamStop only covers operators licensed by the Gambling Commission, so offshore sites-often advertising as "not on GamStop"-aren't blocked. These platforms sit entirely outside UK consumer protection, and the Gambling Commission has even linked some to criminal activity targeting self-excluded individuals. Frankly, they're not a loophole worth testing. See our guide to gambling age and UK gambling law for more on why non-UK sites offer no safety net for British players.

How to block the sites GamStop doesn't reach

Since GamStop can't reach offshore sites, the best way to plug the gap is with blocking software. These tools work at the device or bank level, no matter where a site is licensed.

Two tools are available free for UK residents. Gamban blocks gambling websites and apps across all devices and is available free via TalkBanStop-the support partnership that brings together the National Gambling Helpline, GamStop, and Gamban. BetBlocker is a charity-run app that blocks tens of thousands of gambling sites, licensed and unlicensed, on most operating systems.

Most UK banks and building societies now offer gambling transaction blocks, which stop card payments to betting merchants and often come with their own cooling-off period before they can be lifted. Combining these layers-GamStop, a blocker, and a bank block-offers far stronger protection than relying on any single measure.

Getting support alongside self-exclusion

Self-exclusion tackles access, but doesn't address what's driving the urge to gamble. It's worth pairing with meaningful support.

The National Gambling Helpline, operated by GamCare, is free and open 24 hours a day on 0808 8020 133, by phone or live chat. Advisers offer support without judgement and can provide a free Gamban licence straight away.

For treatment, the NHS runs specialist gambling clinics across the country-self-referral is possible, with no need to go through your GP. Gamblers Anonymous provides free peer support through local and online meetings.
