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.

Two things to check for yourself

We have not confirmed two items for any of the five casinos, and both are in the casino's own terms. The first is the customer funds rating: search the terms for 'insolvency' and you will find 'not protected', 'medium protection' or 'high protection'. The second is the dispute resolution service: search for 'dispute' or 'ADR' to find the independent body that hears complaints the casino has not resolved. Both take about a minute.

Why this site lists five casinos

Because five is the number we have checked. Each has had its licence confirmed on the public register, its operator identified and its regulatory record looked up, and the offer terms read. Long lists of the top 20, 50 or 100 casinos are usually ordered by commercial arrangement and rarely give a licence number. The public register is the only complete list of UK casinos, and it is free to search.

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.
