Casinos not on GamStop: what they are and why they are risky

Casinos not on GamStop are online gambling sites that hold no Great Britain operating licence, which is exactly why GamStop cannot reach them: the scheme covers operators the Gambling Commission licenses, and nobody else. Since 31 March 2020, taking part has been a condition of every GB licence, and GamStop’s own terms state that it is "unable to help prevent you from accessing gambling services that are operated by organisations which do not participate in GAMSTOP".

Being outside GamStop is not one missing feature. The same licence that puts an operator into the scheme is what also gives you free complaint adjudication, rules about how your deposited money is held, a prompt to set a deposit limit before your first payment, and identity checks before you gamble. On a non-GamStop site all of it is absent at once. The Gambling Commission summarises what is left for consumers on the illegal market as "increased risks from unfair gaming practices, financial loss, and a lack of recourse if things go wrong" (October 2025).

Non-GamStop means unlicensed in Great Britain, not lighter rules

The phrase "non-GamStop" describes an absence rather than a category of licence, and the same is true of the related labels: betting sites not on GamStop, slots not on GamStop, non-GamStop sites, casinos not registered with GamStop. Each names a missing GB licence, not a different kind of product. What these sites are not:

• Not a second self-exclusion scheme. GamStop is the national online self-exclusion scheme for Great Britain. There is no parallel register that non-GamStop sites belong to instead.
• Not operators who opted out. A GB-licensed operator cannot choose to leave; participation is a licence condition, in force since 31 March 2020.
• Not made lawful by a Curaçao or Malta licence. An overseas licence authorises the operator in that jurisdiction. It does not authorise providing facilities for gambling to people in Great Britain, which is what section 33 of the Gambling Act 2005 regulates.
• Not a list anyone maintains for your benefit. The pages that rank for these searches are produced by the operators and their affiliates, not by a regulator or a consumer body.

Why people look for casinos not on GamStop after self-excluding

Typing "casinos not on gamstop" after registering with GamStop does not mean the block failed. It means the block held: the accounts closed, and the urge went looking for a gap. The gap is also where the marketing is aimed. The Gambling Commission has recorded unlicensed operators targeting "vulnerable consumers through internet search terms such as 'NotonGamstop'", so the listings returned by that search are advertising written for people who have already excluded themselves.

If the urge is live right now, the useful page is how to get through a gambling urge at night rather than anything further down this one.

What the GB licence gives you, and what disappears without it

A Gambling Commission licence is a bundle of specific obligations owed to you, and a site outside it owes none of them. The differences that matter most in practice:

The last row is the one that turns into arguments about money. On a GB-licensed site, a refusal to pay is a dispute you can hand to a free adjudicator: IBAS describes itself as an independent ADR service for disputes between licensed gambling businesses and their customers, free for consumers, with decisions binding on the business up to £10,000. Off the licensed market there is no equivalent. A site that decides your account was duplicated, your bonus was abused, or your documents were insufficient is the first and last word on it.

The legal position: an offence for the operator, not the customer

Under section 33 of the Gambling Act 2005, a person commits an offence if they provide facilities for gambling without holding an operating licence that authorises the activity. On summary conviction that carries up to 51 weeks’ imprisonment (six months in Scotland), a fine up to level 5 on the standard scale, or both. The offence falls on whoever provides the gambling, not on the person placing the bet.

Affiliate pages lean on that distinction, and it is where their reassurance stops: not being prosecuted is not the same as being protected. The operator carries the legal risk; the customer carries the financial one.

Non-GamStop brands are a moving target, not a settled market

Unlicensed operators, in the Gambling Commission’s description, are "actively targeting British consumers by manipulating search engine results, exploiting social media platforms, and integrating with payment systems". The regulator is removing those results continuously. Its October 2025 report on disrupting illegal online gambling recorded 447,778 URLs referred to Google and Bing since April 2024, of which 287,961 were removed, alongside 3,140 cease-and-desist and disruption notices.

For a customer, that churn is a practical risk rather than a statistic. A brand recommended on a listing page this month can be delisted, renamed or simply gone next month, and any balance sitting in the account goes with it.

What to do in the next ten minutes

1. Turn on your bank’s gambling block. It takes a couple of minutes in the app. Bank of Scotland, Barclays, Halifax, HSBC, Lloyds, MBNA, Monzo, NatWest, Royal Bank of Scotland, Santander and Starling all offer one, and some, including HSBC, keep declining gambling transactions for a set period even after you lift the restriction. Our guide to bank gambling blocks covers the settings bank by bank.
2. Message or call a helpline. Free and confidential, and faster than deciding alone: see the helplines by country or the UK help page.
3. Work the urge down instead of arguing with it. The techniques that hold up at 2am are in how to stop a gambling urge at night.

If you have already deposited or lost money

Money deposited with an unlicensed operator is usually not recoverable. There is no ADR provider to adjudicate, no licence condition to enforce, and no regulator with jurisdiction over the business, which is what the Commission means when it lists "a lack of recourse if things go wrong" among the risks.

Card chargeback exists for payments where you did not receive what you paid for, or where it arrived faulty or not as described, and the business can challenge a chargeback even after it has been granted. A deposit that landed in your gambling account and was then staked does not normally meet those grounds. Three situations are still worth raising with your bank, because they are different questions: the payment went through after you had asked for a gambling block, the card was used by someone other than you, or money left the account without your authorisation. If the bank refuses and you think it handled the case badly, the Financial Ombudsman Service can review the bank’s decision.

Where the loss has left debt behind, treat the debt as debt rather than as something to win back. What to do about gambling debt sets out the order of operations, including which creditors to contact first and where free debt advice comes from.

Closing the loophole properly

GamStop, blocking software and a bank block work on three different layers, and the gap that non-GamStop sites sell into only closes when all three are in place.

• Account layer. GamStop closes your accounts across every GB-licensed operator and follows you to any device. It stops where the licence stops.
• Device layer. Blocking software never asks who licensed a site, which is why it is the layer that reaches unlicensed ones. Gamban’s own account of what self-exclusion misses is direct: it "doesn’t block illegal or unregulated websites" and "doesn’t stop access to crypto casinos, trading-style platforms or novel products that don’t fall under gambling regulation". Our notes on Gamban and on blocking gambling sites on iPhone and Android cover setup.
• Payment layer. A bank block declines the transaction regardless of which site it is going to, and unlike the other two it is free and takes effect immediately.

Each layer has a known limit. Blocking software protects only the devices it is installed on, so a spare laptop or a work phone stays open. A bank block covers only that bank’s cards, so a second account or a prepaid card goes around it. GamStop stops at the GB licence. The layers are worth installing together because each one covers a gap the others leave.

Telling one person

Blocks are easier to keep in place when someone else knows they exist, and the moment of searching for a way around them is when a second person makes the most difference. That can be a helpline adviser rather than family, and it does not require a full account of the finances. If you would rather someone read up before you talk, how to help someone with a gambling addiction is the page to send them.
