Every Saturday between August and May, several hundred thousand people in Britain want to place a bet on a football match and cannot do it at the bookmaker they used to use. Not because they have been banned, and not because they have done anything wrong. Because they asked to be blocked.

GamStop is the national self-exclusion scheme for online gambling in Great Britain. You register once, for free, and every operator holding a UK Gambling Commission licence has to refuse you — at sign-up, at login, and at deposit. It is one of the more effective pieces of consumer protection in the gambling sector, and it is precisely why the phrase “not on GamStop” exists at all.

This piece is about that phrase: what it means, why sports fans run into it more often than casino players, and what the data says about who is affected. It is not an argument for getting around a self-exclusion. If you excluded because betting was hurting you, the rest of this page is not for you, and there is a link at the end to something more useful.

What the self-exclusion numbers actually show

GamStop publishes half-yearly data, and the 2025 figures are worth reading if you follow football.

Registrations rose 19% in the first half of 2025 compared with the same period the year before. May 2025 set a monthly record at 10,344 registrations. The fastest-growing group was 16–24 year olds, up 44% year on year, and under-25s now make up more than a quarter of new registrations. Four in ten of that youngest group chose the shortest available exclusion, six months.

The football connection is not incidental. GamStop runs an annual Self-Exclusion Day with support from English Football League clubs — ten of them in the most recent campaign, reaching a combined audience of more than 1.7 million supporters. The scheme’s own data shows registrations dipping during England’s World Cup matches and rebounding afterwards. Whatever else that tells you, it tells you that a large part of the self-exclusion population is thinking about gambling in the same rhythm as the fixture list.

The geography is telling too. The ten areas with the highest proportion of residents registered for online self-exclusion are led by Kingston upon Hull at 2.8%, followed by North East Lincolnshire, Blackpool and Hartlepool. These are not the areas with the most betting shops or the biggest Premier League clubs. They are the areas where the scheme has been taken up most heavily — which is a different and more complicated thing.

None of this is a reason to look for a workaround. It is context for why the question comes up so often in sports writing.

What “not on GamStop” means, precisely

GamStop covers operators licensed by the UK Gambling Commission. A bookmaker licensed in Curaçao, Anjouan, Kahnawake or anywhere else has never been part of the scheme, so a self-exclusion registered with GamStop does not reach them.

That is the whole definition. “Not on GamStop” does not mean “unregulated”, “untested” or “safer”. It means “licensed somewhere other than the UK, and therefore outside a scheme that only UK licensees must join”. The phrase is used in marketing as though it were a feature. It is closer to a description of where the operator sits.

It is worth separating the two things the phrase gets used for. Sometimes it means a site genuinely operating under a different regulator with its own rules. Sometimes it means a site that should be licensed for the UK market and is not. Those are different situations with different consequences, and the second one is the reason the Gambling Commission devotes a standing team to unlicensed operators.

Is it legal? The distinction most articles get wrong

Placing a bet with an unlicensed operator is not, in itself, a criminal offence for the customer in Great Britain. The offence sits with the operator: providing facilities for gambling without a licence is an offence under the Gambling Act 2005.

But “not illegal for the player” is not the same as “you are protected”. This is where the honest version of the story is less comfortable than the marketing.

If you bet with a UK-licensed operator and something goes wrong — a disputed bet, a withheld withdrawal, a frozen account — you have routes. The operator is bound by Gambling Commission rules on complaints, and you can escalate to an alternative dispute resolution provider. If you bet offshore, you have whatever that operator’s licence says you have, enforced by a regulator in a jurisdiction you probably cannot reach, under a process you probably cannot use.

The practical version: your money is not held to UK standards, your complaint has no UK home, and no British regulator will act for you.

What you give up, in concrete terms

The fourth row matters more than people expect. UK-licensed operators are constrained in how they can market to you — bonus terms have to be clear, and inducements to people showing signs of harm are restricted. Offshore operators advertising into the UK sit outside those rules, which is part of why their offers tend to look larger and less qualified.

How to check a licence in about five minutes

If you are going to look at an operator outside the UK system, the licence is the first thing to verify and the easiest to check.

1. Find the licence number. It should be in the footer of the site and in the terms. If you cannot find it, stop there — that is the answer.
2. Check it against the regulator’s own public register. Curaçao, the Malta Gaming Authority and the UK Gambling Commission all publish searchable registers.
3. Match the company name, not the brand name. A site trading as one name is often operated by a company with an entirely different one, and the licence is held by the company.
4. Check what the licence actually permits. A Curaçao licence and an MGA licence are not equivalent, and neither is equivalent to a UKGC licence.

We keep a fuller breakdown of what each licence type means in practice, and which of the sites we compare hold which, at no-gamstop.com — including the fact that several brands sharing an operator can sit on a single permit, which is worth knowing before you assume two sites are independent.

The part that does not fit the marketing

In December 2025, the Guardian published an investigation into an international network of offshore bookmakers that appeared to be built specifically around people who had self-excluded through GamStop. The reporting described operators targeting a population that had already decided to stop.

That is the honest frame for this whole category. The reason offshore bookmakers are attractive to a self-excluded player is the same reason they are risky: they are outside the system that person asked to be inside. A site that markets itself on being outside GamStop is, whether it says so or not, marketing to people who chose to be blocked.

If that describes you — if you registered with GamStop because betting had stopped being fun and started being a problem — the useful page is not this one. GamStop itself, GamCare and BeGambleAware all offer support, and none of them require you to explain yourself first.

Where to go next

If you are reading this as a sports fan curious about how the market is structured, rather than as someone looking for a way around a block, the useful next step is understanding what the offshore sportsbook market actually looks like compared with the UK one. It is smaller, more crypto-native, and thinner on the British racing and football markets that UK-licensed bookmakers compete hardest for.

We keep that comparison — markets, margin, cash-out rules, withdrawal speeds and which of the operators we track actually run a sportsbook — at no-gamstop.com/sports-betting-sites. It is written for people who want to understand the category, and it says plainly where the category is worse than the UK-licensed alternative.

Frequently asked questions

Can I bet with a UK bookmaker if I am on GamStop?

No. Every operator holding a UK Gambling Commission licence must check the GamStop register and refuse you while your exclusion is active. There is no legitimate way around that, and attempting one usually means dealing with an operator that is not licensed for the UK at all.

Are betting sites not on GamStop illegal?

For the customer, placing a bet is not an offence. For the operator, providing gambling facilities to British customers without a licence is an offence under the Gambling Act 2005. The Gambling Commission pursues operators, not players.

How long does a GamStop exclusion last?

You choose at registration — six months, one year, or five years. The shortest option is the most popular among younger registrants. You can extend it, and the scheme’s guidance covers what happens at the end of the period.

Do offshore bookmakers cover British football and horse racing?

Some do, but coverage is generally thinner than at UK-licensed bookmakers, who compete hardest for exactly those markets. British racing in particular is licensed in a way that makes it harder for offshore operators to offer the same product.

What is the difference between a Curaçao and an MGA licence?

They are different regulators with different rules, different complaint processes and different levels of published information about the operator. Neither is a UK licence. Treating them as interchangeable is the most common mistake in this category.
