What GamStop actually is
GamStop is a free self-exclusion database used by every online gambling operator licensed by the UK Gambling Commission. It launched in 2018 and has grown steadily since. It is not a government service, not a bank block and not an app you install. It is a shared list of identifying details that operators are required by their licence to check.
A simple description in plain English
If you register with GamStop, you supply a small set of personal identifiers such as your name, date of birth, postcode and email. Those details are hashed and shared with every UKGC-licensed operator. When you later try to register at, or log in to, any of those operators, they check the list. If your details match, the operator is required to refuse. There is no fee. There is no paper trail visible to third parties. It is a quiet technical block.
Jonah Whitcombe covered the launch of GamStop for BBC Radio 4 in 2018 and has followed its rollout since. The scheme has evolved considerably. What began as a voluntary tool became a mandatory requirement for every UKGC operator to consult in 2020, and now the database holds well over half a million active registrations.
Who it is for
GamStop is intended for adults in Great Britain who want to stop gambling online with UKGC-licensed operators for a defined period. It is not gated by proof of gambling harm. Anyone eighteen or over can register, whether they gamble heavily, occasionally or not at all. A person setting up GamStop before their first bet is using the tool exactly as intended.
It is deliberately not a diagnostic tool. Registering does not put a mark on your credit file, does not appear on a background check and does not affect your employment. It is a private commitment shared only with the operators that need it.
Who runs GamStop and pays for it
Understanding who owns and funds GamStop matters, because the answer sometimes surprises readers. It is not a government scheme, and it is not paid for directly by taxpayers.
The company behind the scheme
GamStop is run by The National Online Self-Exclusion Scheme Limited, often shortened to Nossl internally but branded to the public as simply GamStop. It is a not-for-profit company limited by guarantee, registered in England and Wales. Its board includes senior figures from the gambling industry and from the treatment and advocacy world. Governance is public and its accounts are filed at Companies House.
The company sits at arm's length from the UK Gambling Commission, which sets the licence condition that requires operators to consult the database. The Commission regulates operators, but does not operate GamStop directly. That separation is important for the same reason a court is separate from the police it relies on.
Where the funding comes from
The scheme is funded by the UK gambling industry through a levy paid by UKGC-licensed operators. Because it costs money to operators every year, there is a natural check on the way the industry engages with it. Costs are published in the annual accounts. As of the most recent published figures, GamStop's operating budget runs into the low millions of pounds a year, funding a small full-time staff, a technical platform and the customer support team that handles registrations and enquiries.
The user pays nothing. Registration is free, the block is free, and there is no premium tier. The scheme's independence is protected by that structure.

How to sign up for GamStop
The signup process is deliberately simple. It takes about ten minutes and requires only the personal details a gambling operator would need to identify you.
The details you need
You will be asked for your legal name (first and last), date of birth, address including postcode, mobile phone number and email address. Providing a middle name and any previous names or postal addresses helps the database match against operator records more accurately. If you have opened gambling accounts under any spelling variant of your name, include those spellings.
You will be asked to choose the length of the exclusion. Options are six months, one year or five years. There is no shorter option and no cooling-off length beyond five years. You confirm by clicking a link sent to your email and typing a phrase to acknowledge that you understand the exclusion is not easily reversible.
How long it takes to become active
The registration is active within 24 hours across all UKGC-licensed operators. In practice most operators refresh their local mirror of the database every few hours, so effective coverage often kicks in within hours rather than a full day. Any gambling accounts you already hold with UKGC operators will be closed or suspended automatically once the database is refreshed. You do not need to close each account individually.
If for any reason a UKGC operator continues to allow you access after 24 hours, that is a licence breach on the operator's part. You can report it to the UK Gambling Commission at gamblingcommission.gov.uk, and GamCare on 0808 8020 133 can also help you escalate.
How to check whether a casino is on GamStop
A common reader question is how to verify whether a specific casino participates in GamStop. The answer is more direct than most people expect. The six steps below walk through it patiently.
The six-step check
- 1Scroll to the site's footer. Every online gambling site is required by industry norms to state its regulator at the bottom of the page. Look for the licensing body name and licence number.
- 2Read the regulator line carefully. If it says UK Gambling Commission and quotes a licence number, the site is UKGC-licensed and therefore participates in GamStop.
- 3If it names a different regulator, note it. Curaçao Gaming Control Board, Malta Gaming Authority, Isle of Man Gambling Supervision Commission, Kahnawake Gaming Commission, Gibraltar Gambling Commissioner or Anjouan Gaming Authority all point to offshore licensing, which means the site is not on GamStop.
- 4Verify the licence at the regulator's own register. The UKGC public register is at gamblingcommission.gov.uk. Malta at mga.org.mt. Isle of Man at gov.im/gambling. Search for the operator name or licence number to confirm the footer claim.
- 5If in doubt, test with a registration attempt. If you already hold an active GamStop registration and the operator lets you complete signup and log in, the site is not on GamStop. A UKGC-licensed site would refuse the account.
- 6Contact GamStop or GamCare with any doubts. GamStop customer support is contactable through gamstop.co.uk. GamCare's helpline on 0808 8020 133 can help you interpret what you are looking at.
Why the footer alone is not always enough
Sometimes a casino uses a UK-facing brand name but is actually operated by an offshore entity. In those cases the licensing line in the footer is the real answer, not the URL or the marketing. Some brands share names with other companies that are UKGC-licensed, adding a further layer of confusion. Reading the footer, then verifying at the regulator's own register, gets you past that confusion in almost every case.
Jonah Whitcombe's editorial rule when covering this area is that if the footer cannot be reconciled with a regulator's own register within a few minutes, the site does not deserve the benefit of the doubt.

What GamStop covers and what it does not
Understanding the boundary of GamStop is more useful than the fact that it exists. A block that covers the wrong things is a source of false confidence. Below is what it actually does and does not reach.
What GamStop covers
GamStop covers all online, mobile and telephone gambling with UKGC-licensed operators. This is a very large slice of gambling activity available to UK residents. It includes online casinos, online sportsbooks, online bingo, online poker, online instant-win games and online lotteries, plus any of those services offered over the phone or through a UKGC-licensed app.
Once active, an existing account cannot be logged into. A new account cannot be opened. Marketing emails from those operators should stop within a short window as your details flow through their systems.
What GamStop does not cover
GamStop does not cover offshore online gambling. A casino licensed in Curaçao, Malta (unless it also holds a UKGC licence), the Isle of Man, Gibraltar, Anjouan or by the Kahnawake Gaming Commission is not obliged to check GamStop and typically does not. This is the definitional gap that gives rise to the phrase non-GamStop casinos.
GamStop also does not cover physical gambling. Betting shops, casinos, bingo halls and arcades run separate schemes such as SENSE for casinos and BOSE for bookmakers. It does not cover the National Lottery, which has its own self-exclusion arrangement. It does not cover unregulated poker games among friends. And it does not, by itself, block bank payments to gambling merchants. That last one is best handled by a bank gambling block, which every major UK bank now offers for free.
How self-exclusion works day to day
The first few weeks after a GamStop registration have a distinctive rhythm. Marketing emails taper off. Familiar sites stop letting you log in. Push notifications from apps go quiet. Knowing what to expect makes the change easier to sit with.
The first fortnight
Within 24 hours of registration your existing UKGC-licensed accounts should show as suspended or closed when you attempt to log in. Marketing emails will continue briefly for a few days until each operator processes the exclusion internally. If you are still receiving marketing after roughly two weeks, that is worth reporting either to the operator directly or to the UK Gambling Commission.
You may find yourself with unspent balances in old accounts. Operators are required to return those funds to you. Contact each operator's customer support, request withdrawal of the remaining balance to your original deposit method, and keep the confirmation email for your records.
The longer sit
Beyond the first fortnight, the daily texture is mostly one of absence. Advertising will continue to reach you on other platforms because that flows through advertising networks rather than the operator's own mailing list. Turning off gambling advertising on social platforms is a separate step and worth taking. Facebook, Instagram, X and TikTok all allow users to hide gambling ads in their preferences.
Many people report that the first six months of exclusion feels different from the second six months. Craving patterns shift. Sleep patterns often improve. If those changes come with difficult emotional weather, the GamCare National Gambling Helpline on 0808 8020 133 is a good place to talk it through.
What happens when a GamStop period ends
A GamStop period does not silently expire. It requires an explicit action from you if you want the block lifted. This section walks through exactly what happens as an end date approaches.
The window before the end date
Around the time of your end date, GamStop will contact you to let you know the exclusion is nearing expiry. You have three options. Do nothing, in which case the block remains in place indefinitely. Extend the exclusion, either at the same length or a longer one. Or begin the process of lifting the block, which requires a positive step from you and a mandatory 24-hour cool-off period.
The cool-off period is deliberate. Removing an exclusion should feel slightly effortful, not instant. This is the same principle used by bank gambling blocks and responsible-gambling tools at UKGC operators. A short pause reduces impulsive reversals of a decision made carefully.
After the block is lifted
Once you have completed the cool-off and confirmed removal, the block ends. You can register at UKGC-licensed operators again. This does not automatically reopen your old accounts, since many operators close accounts permanently when a GamStop registration triggers, so you may need to open new ones.
Many people who lift a GamStop exclusion later re-register. That is entirely normal and does not carry any stigma or record. If lifting an exclusion feels risky, starting with a shorter re-registration and building up to a longer one is a reasonable middle path. The tool is designed to be used repeatedly if that suits you.

How GamStop compares to Gamban and BetBlocker
GamStop is one of several self-exclusion tools available to UK players. Gamban and BetBlocker sit alongside it, and each does something different. Understanding the split is useful when choosing which tools to combine.
GamStop, Gamban and BetBlocker in one paragraph each
GamStop works at the operator level. It blocks UKGC-licensed sites from opening an account for you. It requires no software on your device. It is completely free.
Gamban works at the device level. It installs on Windows, macOS, iOS and Android and blocks access to gambling websites and apps globally, including non-GamStop casinos. It is a paid subscription with a free trial, currently around £24.99 a year at the time of writing.
BetBlocker also works at the device level and blocks a similar list of sites. It is free, open source and can be installed on multiple devices. It is a smaller operation than Gamban and its list of blocked sites is more limited, but for zero cost it is a valuable second layer.
Why using more than one is stronger
Each tool has a different failure mode. GamStop covers UKGC operators but not offshore ones. Gamban and BetBlocker cover most sites at the device level but can be defeated by using a different device. Combining GamStop with a device-level blocker, then adding a bank-level gambling block on top, closes the main gaps. If gambling harm is a live concern, layering all three is a stronger foundation than relying on any single tool.
Jonah Whitcombe consistently recommends layering when he covers this ground. The goal is not to build a perfect single wall but to create enough friction that impulse decisions have time to pass. Friction, not perfection, is the mechanism.
Alternatives if you want more control
If GamStop does not fit your needs, or if you want additional layers, several other tools and services are worth knowing about. This section pulls them together in one place.
Bank blocks and card controls
Every major UK bank now offers a free gambling block in its app. Monzo was the first to launch one in 2018, and Starling, Barclays, NatWest, Lloyds, Halifax, Nationwide, HSBC, Santander and TSB followed. Turning on the block prevents card payments to gambling merchants. Most banks apply a cool-off period of at least 48 hours before the block can be lifted. This block works at the payment level and applies to all gambling merchants, including non-GamStop casinos.
Some banks additionally allow you to freeze the debit card entirely from within the app, which is a useful short-term step during a difficult moment.
Counselling and peer support
GamCare runs free structured treatment programmes across Great Britain, including one-to-one counselling, group programmes and residential treatment. The National Gambling Helpline on 0808 8020 133 is the way in. GamCare also runs a live-chat service on its website. The National Health Service operates specialist gambling clinics in several English regions, with referrals usually made through a GP.
Peer-led support includes Gamblers Anonymous, which runs in-person and online meetings across the country. Family members can access Gam-Anon and GamCare's affected-others service. None of these are exclusive to any particular type of gambling, and all of them can support someone regardless of whether they are also on GamStop.
