Best Non GamStop Casino Sites – UK Casinos not on GamStop

What Are Non GamStop Casinos?

If you’re a UK player who is in GamStop, non-GamStop casinos are the only option you’ll have as they operate independently of the UKGC. International or offshore licences are the name of the game for casinos not on GamStop, which lets them provide larger bonuses (such as NationalBet’s 200% Up to £500 + 200 FS welcome bonus), a richer array of payment methods (especially cryptocurrencies), and self-exclusion is not mandatory but optional. These casinos often make the playing experience more relaxed because the regulations that govern them aren’t as stringent.

Non-GamStop UK Casinos vs UKGC Casinos

There are a couple of major differences between UK casinos not on GamStop and those with a UKGC licence. Below you will find our comparison so you have a broader view of what each type of casino excels at.

Why Choose Non GamStop Casinos in 2025?

GamStop and the UKGC limit how you approach gambling, and there are mandatory self-exclusion tools that will block access to UKGC-licensed casinos. They also require more detailed personal information, including your ID card, proof of residence, proof of income source, and proof of financial ownership, among others. If you don’t want to go through this process, a non GamStop casino generally won’t need that much of your info, and all self-exclusion features are optional.

More payment methods and a larger game collection mean non GamStop casinos are very versatile and open to all kinds of players. Highrollers are welcomed and rewarded for their luxurious approach to gambling; something you won’t find at UKGC-regulated casinos.
