Casinos Not on GAMSTOP: What the Phrase Actually Means

“Casinos not on GAMSTOP” is one of the two largest search terms taking British players to unlicensed gambling sites — the Gambling Commission’s own research into illegal markets says so. It is worth understanding exactly what the phrase describes, because the marketing version and the legal version are very different things.

Stripped of the packaging, a casino “not on GAMSTOP” is a casino that is not licensed in Great Britain. That is the whole of it. The scheme is a licence condition, so being outside the scheme and being outside the law are the same fact stated two ways.

How GAMSTOP actually works

GAMSTOP is the national online self-exclusion scheme, run by The National Online Self Exclusion Scheme Limited. You register once, choose a minimum period, and every participating operator checks the register when you try to log in or open an account.

Two details that most pages on this subject get wrong:

• There are four options at registration, not three — six months, one year, five years, or five years with automatic renewal. The auto-renewal option rolls into a new five-year period on expiry, up to four further times, and can be switched off from your account after four years and six months.
• Your exclusion does not lift by itself. GAMSTOP’s own terms of use, updated 20 May 2026, say it plainly: they will not “automatically remove your self-exclusion at the end of a Minimum Exclusion Period, or contact you to let you know that a Minimum Exclusion Period has expired.” You stay excluded until you actively complete the deactivation process. The niche myth that a six-month block simply falls away is wrong.

The numbers, from the scheme itself

GAMSTOP published its half-year data on 16 July 2026:

• 614,738 people are currently registered — most competitor pages still quote a figure from late 2025 that is more than fifty thousand out of date.
• Registrations in the first half of 2026 were up 16% year on year, with a record 12,236 in May alone.
• Under-25 registrations rose 26% and now account for almost one in three new self-exclusions.
• More than half of all registrants chose the maximum five-year term.
• 177 companies participate, as listed on 5 August 2026 — many covering several brands each.

Why offshore sites are outside the scheme

This is a legal question with a clean answer, and it is not “because they are more generous”.

Participation in GAMSTOP is social responsibility code provision 3.5.5 of the licence conditions: “Licensees must participate in the national multi-operator self-exclusion scheme.” It has been mandatory for online operators since 31 March 2020 — and the Commission suspended two operators’ licences within days of that deadline for failing to integrate. The duty was extended to telephone and email betting on 1 April 2024.

An unlicensed operator is not bound by a licence condition, and is not connected to the register. So the chain runs like this:

• Since 1 November 2014, the Gambling Act works on point of consumption. Section 36 was rewritten so that section 33 applies where “the facilities are used” in Great Britain, wherever the equipment sits.
• Section 36(3A) sets the test: the operator commits an offence “only if the person knows or should know that the facilities are being used, or are likely to be used, in Great Britain.”
• A site that markets itself to British players on the phrase “not on GAMSTOP” knows precisely who its customers are.
• It is therefore providing facilities for gambling in Great Britain without a licence — an offence under section 33.
• Not being a licensee, it is not bound by provision 3.5.5 and is not plugged into the register.

What the regulator’s own research found

The Commission commissioned two studies into illegal online gambling, published on 18 September 2025. The findings are more useful than any commentary, because they measure behaviour rather than opinion.

From the quantitative phase, base 2,046 respondents:

• 10% of people who had gambled online in the previous four weeks had used GAMSTOP at some point.
• Of those, four in ten found a way to gamble using their own account.
• 9% said they had deliberately played on unlicensed sites; among 18 to 34-year-olds that rose to 20%.
• 10% had reversed a withdrawal — cancelling a cash-out to put the money back into play.
• 9% of online gamblers had deposited using cryptocurrency.

The qualitative phase recorded how self-excluded people found these sites, in their own words: “I googled ‘gambling sites not on GAMSTOP’ and found them that way.” On the marketing that followed: “I’ve changed my phone number so many times but somehow, they still get hold of me.” And on how it felt afterwards: “They are deliberately targeting people who have self-excluded.”

The same research recorded what actually happened on those sites: glitchy platforms, miscalculated winnings, withdrawal difficulties.

What the Commission is doing about it

From its disruption reporting published 21 October 2025, cumulative since April 2024:

Action	Count
Cease-and-desist and disruption notices issued	3,140
— of which cease-and-desist notices to illegal operators	2,032
— referrals to domain registrars	774
— referrals to hosting providers	402
URLs referred to search engines	447,778
URLs removed	287,961 (64.3% of those referred)

The practical consequence for a player is worth spelling out: these sites disappear. A domain that vanishes takes any balance on it with it, and there is no regulator to appeal to.

What does work, if a block is what you need

GAMSTOP covers licensed operators only, so it cannot reach an unlicensed site. Device-level blocking can. Being straight about the current state of that, because it changed in 2026:

• BetBlocker — free, anonymous, no registration required, and it blocks tens of thousands of gambling domains including unlicensed ones.
• Gamban — changed its model on 31 March 2026. It is now a paid subscription (£4.99 a month) in England and Scotland, and remains free for residents of Wales. Note that GAMSTOP’s own site still describes both as free for UK residents — that page has not caught up, and Gamban is the one to check before relying on it.
• Bank-level gambling blocks — useful but imperfect. Monzo has publicly acknowledged that “sometimes transactions aren’t tagged with the correct information, meaning these transactions bypass any blocks.” Crucially, buying cryptocurrency on an exchange is not coded as a gambling transaction, so a gambling block will not stop it.

Frequently asked questions

Does my GAMSTOP exclusion end automatically?

No. GAMSTOP’s terms state that it will not automatically remove your self-exclusion when the minimum period expires, and will not contact you to say it has. You remain excluded until you actively complete the deactivation process.

Is it illegal for me to play at a casino not on GAMSTOP?

Not for you. The offences in the Gambling Act 2005 apply to the operator providing unlicensed facilities and to those advertising them. There is no offence of being the customer. What you lose is every protection attached to the licence — including any way to get your money back. See our page on crypto gambling and UK law.

Can GAMSTOP block offshore casinos?

No. It is a licence condition, so it reaches only operators licensed in Great Britain. For device-level blocking that covers unlicensed sites, BetBlocker is free and requires no registration.

How many people are on GAMSTOP?

614,738 as at the scheme’s half-year data published on 16 July 2026, across 177 participating companies. Registrations were up 16% year on year, with under-25s the fastest-growing group.
