Every GamStop casino UK player can rely on — tested and verified March 2026. These are the casinos on GamStop: UKGC licensed, legally bound to block your account if self-excluding. I put real cash into each GamStop online casino listed below, verified the licence numbers on the official register and checked GamStop registration myself. No exceptions. No waiting.

GamStop is a service that's free and available all over the United Kingdom. When you sign up with GamStop you are stopped from using every UKGC gambling site in the country. That is what GamStop is about. GamStop started in 2018. It became a rule for all licensees in 2020. Before GamStop people had to call each casino and ask them to stop them from playing. This was a slow process. Now things are much easier. All you have to do is fill out a form on the GamStop website which is gamstop.co.uk and you will be stopped from using all the sites.
Here is how GamStop actually works:
GamStop is completely free to use. It is paid for by a fee on the UKGC licensees. It is separate from the operators. If you are worried about your gambling you can visit gamstop.co.uk or you can call the National Gambling Helpline on 0808 8020 133. This is a service that's available twenty-four hours a day seven days a week. You have to be eighteen years old or more to use this service.
March 2020 was when the UKGC made it a must for online casinos to be on GamStop.
The UKGC said it was not a suggestion. A rule.
If a casino does not join GamStop it will lose its licence.
That's straightforward.
If a casino has a UKGC licence it is on GamStop.
There are no exceptions.
There are no ways around it.
Before the rule self-exclusion was a hassle.
You could self-exclude at one casino, like LeoVegas. Then sign up at another like bet365 on the same day.
No one stopped you.
The systems were different. So were the databases.
GamStop fixed this by creating a database that all licensed casinos must check before letting you have an account.
When I list the online casinos in the UK every single one of them is on GamStop.
The UKGC licence number is your guarantee.
You do not need to ask if a casino is on GamStop.
The licence number tells you.

All five casinos hold a UKGC licence and are registered with GamStop. Sorted by overall score from our March 2026 testing.
Registering with GamStop is really easy and it does not take a lot of time it takes under five minutes. It is completely free. Here is the full process to register with GamStop.
You need to go to gamstop.co.uk and click on "Register". You should know that GamStop is the scheme so you need to be careful of other sites that are not official.
You need to give them your name, date of birth email address, postal address and mobile number. They use these details to match them against casino databases. You should use the details you use at GamStop and other gambling sites because if you use nicknames or old addresses it may not work properly with GamStop.
You need to choose how you want to exclude yourself from gambling with GamStop. You can choose 6 months, 1 year or 5 years with GamStop. You need to think about this because once you start you cannot change your mind or make it shorter. If you are not sure it is better to choose the longer option.
GamStop will send you a verification email or SMS. You need to confirm your registration by clicking on the link or entering the code. You need to do this because your exclusion is not active until you complete this step.
Once you verify your registration GamStop shares your details with all UKGC-licensed operators. They have to block your account within 24 hours. Most of them do it within a few hours. Then your exclusion from gambling is active.
Registering with GamStop is an idea but it works even better if you get some extra help. You should think about contacting BeGambleAware GamCare or calling the National Gambling Helpline on 0808 8020 133. It is free. They are available 24/7. You have to be eighteen years old or more to use these services.
Once you are registered with GamStop, a few things happen with all the gambling sites that are licensed in the UK.
There are some things that GamStop does not cover. Betting shops, the National Lottery casinos that are not online and sites that are not licensed in the UK. If you want to be safer it is an idea to use GamStop and also get help from GamCare.
