Bonuses that are too good
The bigger the promise, the closer you should look.
By Ryan Jessop. Last checked .
Key takeaways
- UK wagering is capped at 10x.
- Huge match percentages are rare here.
- Large free bonuses are bait.
- Real offers are modest.
In shortA genuine UK casino bonus sits within the 10x wagering cap and shows its significant terms. Offers of several hundred percent, or large sums with no deposit, almost always come from unlicensed sites.

Why modest is a good sign
A licensed casino has to be able to afford its offer under rules that limit how hard it can make the terms.

Where to get help
If you are looking for a way round limits you set yourself, or gambling is costing more than you can afford, free and confidential support is available at any hour. The National Gambling Helpline, run by GamCare, is on 0808 8020 133. GAMSTOP blocks you from every UK-licensed gambling site, and most banks can block gambling payments on your card. None of these costs anything.
What makes an online casino a UK casino
Not its address or its branding, but its licence. An online casino may offer gambling to people in Great Britain only if its operator holds a remote operating licence from the Gambling Commission. That licence brings binding rules: identity checks before play, bonus wagering capped at ten times, slot stakes capped at £5, no credit cards, tested games, a named dispute resolution service and membership of GAMSTOP. Every casino site, slot site and live casino described on this page is judged first on that.
If the casino is not licensed
None of this applies. There is no regulator to complain to, no dispute service, no required testing of games, no obligation to keep your money separate and no GAMSTOP. Money sent to an unlicensed site should be regarded as spent. That is the reason every route through this site starts with the licence check.
Licences were confirmed on the Gambling Commission register; regulatory actions were checked against Commission announcements on 8 October 2026; offer terms on 5 October 2026. Items labelled "reported" come from independent reviews, and items labelled "not checked" we have not confirmed. How we check. 18+. Free help: 0808 8020 133 or safer gambling.
