What the licence requires
A Gambling Commission licence comes with conditions and codes of practice that every operator must follow: verifying customers before play, disclosing how customer funds are protected, offering only tested games, providing limits and self-exclusion, handling complaints within eight weeks and naming a dispute resolution service. Breaches can bring fines, added conditions, suspension or loss of the licence, and the outcomes are published.
Opening an account safely
Register through the casino's own site or a link you trust, using your legal name and current address. Verify your identity straight away. Set a deposit limit before the first deposit. Deposit the minimum by debit card, play a little, and make one small withdrawal: how it is handled tells you more than any review. Read the welcome offer's terms, or decline the offer, before you pay anything in.
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.
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.
