Questions readers ask
Are all of these casinos licensed in Great Britain?
Yes. Each operator's footer gives a Gambling Commission account number, and on 15 November 2026 every one of those numbers matched the licensee on the Commission's public register. The account number in each entry links straight to that register page, so you can check it yourself.
How is the list ordered?
Strictly by overall score, highest first. Every operator is scored the same way from seven published criteria, using only facts from its own UK site. If two operators ever had exactly the same score, the one with the better offer-terms score would go first. The method and every individual score are on How we rate.
What does "10x wagering" mean?
It means you must place bets worth ten times the bonus (or the free-spin winnings, depending on the terms) before that money can be withdrawn. Since 19 January 2026 the Gambling Commission does not allow wagering requirements above 10 times. Our bonus guide works through an example.
Can I use a credit card at a UK online casino?
No. Gambling businesses in Great Britain must not accept credit card payments for gambling, a ban that has applied since 14 April 2020. Debit cards, e-wallets, mobile wallets and bank transfers are the usual options. See payment methods at UK casinos.
Can I gamble on OnlineCasinos4U?
No. This site has no games, accounts or payments. We describe licensed operators and link to their own sites, where their terms apply.
Where can I get help if gambling is becoming a problem?
Call the National Gambling Helpline, run by GamCare, free on 0808 8020 133, at any hour. You can block yourself from GB-licensed gambling sites with GAMSTOP, and BeGambleAware.org has advice and support. More on our safer gambling page.
Gambling should stay a paid-for pastime
Decide what you can afford to lose before you start, set a deposit limit when the casino asks, and stop when that money is gone. If it stops feeling like entertainment, help is free and confidential.
Block every site at once
GAMSTOP is free self-exclusion from online gambling sites licensed in Great Britain.
