Offshore Casinos UK: What the Licence Really Means

Our promise: we never list, link to or recommend a casino that is not licensed by the UK Gambling Commission. The only casinos we name as options hold an active UKGC licence, shown with its number and the date we checked. 18+. How we make money.

Quick answer Offshore casinos UK players see advertised are licensed somewhere else, or nowhere. The Gambling Commission says a licence issued in another country "does not permit an operator to provide gambling to consumers in Great Britain". Only a Gambling Commission licence, shown on its public register, makes a site lawful to serve you.

This hub explains licensing for people who have seen phrases like "non UK casinos accepting UK players" or "Curacao casino sites". It covers what the law says, how to check a licence yourself, and why a foreign licence number does not bring UK protections with it. Every legal statement here comes from the Gambling Commission or legislation.gov.uk, checked on 29 September 2026.

Are offshore casinos legal for UK players?

Offshore casinos are not licensed to offer gambling to people in Great Britain. The Gambling Commission states: "It is illegal to provide gambling facilities to consumers in Great Britain without: an operating licence from the Gambling Commission." It adds that this "applies regardless of where in the world the gambling is provided from".

That is the whole answer in one sentence. A site based in another country, with a licence from another country, still needs a Commission licence to serve you. If it does not have one, the Commission calls what it offers "unlicensed", "illegal" or "unlawful" gambling, and treats those words as interchangeable.

What does a Curacao licence mean for UK players?

For a player in Great Britain, a Curacao licence, or one from Anjouan, Kahnawake or any other authority outside Great Britain, does not mean the site is licensed to serve you. The Commission is explicit: "A gambling licence issued in another country does not permit an operator to provide gambling to consumers in Great Britain."

A foreign licence may place obligations on the operator where it was issued. It does not give you access to the UK's Alternative Dispute Resolution route, UK stake limits, the UK 10x bonus wagering cap or GAMSTOP. Those protections come only with a Commission licence.

What does the law say about advertising offshore casinos?

Section 330 of the Gambling Act 2005 is headed "Unlawful gambling". It says: "A person commits an offence if he advertises unlawful gambling." The Commission summarises the position: "in the absence of a valid defence it is also a criminal offence to advertise unlawful gambling to consumers in Great Britain."

That is why this site does not publish lists of offshore casinos. It is also a useful test when you read other websites. A page that recommends non-UK casinos to UK players is advertising gambling that is unlawful here.

How do you check a UKGC licence?

It takes about a minute on the Gambling Commission's public register.

1. Find the Gambling Commission account number in the website's footer.
2. Search for it on the public register at gamblingcommission.gov.uk/public-register.
3. Check the licence is active and covers the right activity, such as remote casino or remote betting.
4. Open the list of domain names on the entry and confirm the site you are using is on it.

If there is no number, the number does not match, the licence is not active or the domain is missing, the site is not licensed for Great Britain. We use exactly this process for every casino we name on our UK-licensed alternatives page, and we show the licence number and the date we checked.

Why does the UK licence matter so much?

Because it ties the operator to the licensing objectives. The Commission lists them: to "prevent gambling from being a source of crime and or disorder", to "ensure that gambling is conducted in a fair and open way", and to "protect children and vulnerable people from being harmed or exploited by gambling". Each UK protection, from stake limits to ADR, exists to serve one of those aims.

The Commission also points out that illegal operators "create unfair competition for the licensed industry and do not contribute tax, levies or funding for sport", and that they "may have links to wider criminality".

Who enforces the rules?

The Gambling Commission investigates potential offences under the Gambling Act 2005. It says it can "institute criminal proceedings for offences under the Act in England and Wales", while in Scotland "the power to institute criminal proceedings rests solely with the Crown Office and Procurator Fiscal Service". It runs a dedicated Illegal Markets Team and works with payment providers, search engines, social media and technology providers to disrupt unlicensed operators.

In September 2025 its chief executive said: "Since April 2024 we've seen a ten-fold increase in our disruption activity."

Can you report an unlicensed site?

Yes. The Commission's "tell us something in confidence" service accepts reports of "unlicensed gambling or criminal activity". It treats reports "in the strictest confidence". It does not process individual complaints through that service, and it explains that it "cannot provide feedback on any information you provide in case it results in an investigation".

Does a licence number in the footer prove anything?

Not on its own. Numbers and seals can be copied. Search the Gambling Commission public register for the company and the exact web address, and check the licence is active. If the domain is not listed, the site is not licensed to serve players in Great Britain.
