What Is GAMSTOP? The UK Self-Exclusion Scheme Explained

GAMSTOP scheme diagram

GAMSTOP is the UK's national online self-exclusion scheme. A single free registration blocks a user from every online gambling site licensed by the Gambling Commission for a period of the user's choosing. It is not a filter, not a piece of software, and not something the operator has to opt in to — it is a mandatory technical integration that every UKGC-licensed remote operator must maintain. This article covers, in detail, who runs the scheme, what it does and does not cover, how registration actually works, and what happens when your chosen exclusion period ends.

Who runs GAMSTOP and where the funding comes from

GAMSTOP is delivered by The National Online Self-Exclusion Scheme Limited (TNOSES), a not-for-profit private company established for this specific purpose. TNOSES was founded by the Remote Gambling Association and its early development was funded by the industry through GambleAware. Since the scheme became a Commission licence condition in 2020, participating operators pay an annual charge to TNOSES that funds the running costs. That funding structure is worth naming plainly: the industry pays for the tool that excludes its own customers. The scheme is independent of individual operators in its day-to-day operation, and its user data is not shared back to operators for marketing purposes.

What the scheme actually blocks

A single registration blocks the registrant across every online product offered by every UKGC-licensed remote operator. That includes casino, sportsbook, bingo, poker, and lottery products, whether accessed by desktop browser, mobile browser, or dedicated app. It applies to every brand held by a given operator group — so registering does not need to name each brand individually. It also stops direct marketing communications from participating operators to the registered email address and mobile number.

What it does not block is anything held outside the UKGC remote licensing perimeter. That includes retail (physical) betting shops and casinos, National Lottery products (which are separately licensed), gambling operators licensed in other jurisdictions and not holding a UKGC licence, and non-gambling services that happen to involve wagering-adjacent activity such as some social casino games. Bridging those gaps is where supplementary tools such as bank blocks and Gamban come in.

Registration in practice

Registration takes place at gamstop.co.uk. The user provides name, date of birth, postcode, email address, and mobile number. GAMSTOP verifies these details against a range of public and commercial data sources — typically completing within a few minutes — and then propagates the exclusion across all participating operators within 24 hours (in practice, usually within an hour or two for the major operators). A confirmation email is sent, and existing accounts held with participating operators are suspended.

The user chooses at registration the length of the exclusion: six months, one year, or five years. This choice is not reversible during the exclusion period. It is important to be clear about that: once submitted, a GAMSTOP exclusion cannot be lifted early, cannot be shortened, and cannot be paused. That non-reversibility is a deliberate design feature. Self-exclusion schemes that allow easy unwinding are, in practice, easily circumvented in moments of impulse; the friction is the point.

What happens at the end of your chosen period

At the end of the exclusion period, the block does not automatically lift. Instead, the user is asked whether they wish to reactivate access. If no action is taken, the block remains in place indefinitely. If the user chooses to reactivate, there is a mandatory 24-hour cooling-off period before the reactivation takes effect. This "positive-reactivation" model was introduced in 2019 and is a meaningful upgrade on the older opt-out model that some legacy schemes still use.

If the user wishes to extend the exclusion instead, they can do so directly at any point during or at the end of the current period. Extending is always possible; shortening never is.

Effectiveness and what the evidence shows

Research commissioned by GambleAware and independent academic work has consistently found that single-registration multi-operator self-exclusion schemes such as GAMSTOP are among the more effective harm-reduction tools available, particularly when combined with peer support and professional treatment. They are not a complete solution — offshore migration, use of family members' accounts, and reversion at the end of the period all reduce effectiveness — but they raise the friction of continued gambling substantially, and higher friction reliably reduces harm at the population level.

The evidence also shows that people who supplement GAMSTOP with device-level blocking (Gamban) and bank-level card blocks have materially better outcomes than those relying on GAMSTOP alone. That layered-defence approach is covered in our dedicated alternatives article.

Limitations to know about

Three limitations are worth flagging honestly. First, GAMSTOP's reach is defined by the UKGC licensing perimeter — anything outside that perimeter, including all non GAMSTOP casinos discussed on our homepage, is outside the scheme by definition. Second, GAMSTOP's identity-matching relies on the details you provide; a determined circumventor can attempt to register with different details on an offshore site, though this is likely to trip AML checks at withdrawal. Third, GAMSTOP does not cover in-person gambling in betting shops, casinos, or bingo halls — the separate SENSE and SMART Exclusion schemes exist for those environments.

None of these limitations reduce the value of the scheme for what it is designed to do. They do mean that GAMSTOP is best understood as one component of a broader personal harm-reduction strategy rather than a complete answer. For readers seeking that broader picture, our articles on safer gambling tools and UK support services are the appropriate next reading.

Frequently asked questions

Can I cancel or shorten a GAMSTOP registration once it starts?

No. A GAMSTOP exclusion cannot be shortened, cancelled or paused during its term. This is a deliberate design feature to prevent impulsive reversal. You can only extend the exclusion or wait for it to end and then complete a positive-reactivation step.

Does GAMSTOP block offshore or non GAMSTOP casinos?

No. GAMSTOP is limited to operators licensed by the UK Gambling Commission. Offshore or non GAMSTOP sites are outside its reach by definition. To block those as well you need supplementary tools such as Gamban and your bank's gambling block.

Is GAMSTOP free?

Yes. GAMSTOP is free for the user. The scheme is funded by participating UKGC-licensed operators through annual charges paid to TNOSES, the not-for-profit body that runs it.
