How to check a UK online casino licence, step by step

By The Review Room editorial team · Published 14 November 2026 · Updated 14 November 2026 · 5 min read

To check a UK online casino licence, find the company and account number in the site's footer, look it up on the Gambling Commission's public register, and confirm two things: a remote casino activity marked Active, and the site's brand or web address listed under that account. The register is free, needs no sign-up, and also lists businesses that have faced regulatory action.^[1]

Step 1: find the licence details on the casino site

Scroll to the very bottom of any page. A GB-licensed casino normally names the company that holds its licence and gives a Gambling Commission account number, often with a link to the register. Write down both. If the footer names a regulator in another country only, such as Malta, Curaçao or Gibraltar, with no Gambling Commission number, the site is not showing a GB licence.

Do not rely on a badge or logo alone. A link to the register is useful, but follow it and read the record rather than taking the badge at face value.

Step 2: open the business on the register

Go to the Gambling Commission public register and choose the gambling businesses register. Search by account number if you have one, because company names can be similar and brand names often return several results. When we searched for "Mr Green" in October 2026 the register returned three different businesses.^[2]

Step 3: read the licence activities

The business page lists each activity the licence covers, with a status and dates. For an online casino you are looking for an activity called Casino, marked Remote, with status Active and an end date of "Current". A record can hold several activities under one licence number. LeoVegas Gaming PLC's, for example, lists remote casino, bingo, real-event betting and virtual-event betting.^[3]

Step 4: match the brand to the business

This is the step people skip, and it is the one that stops a copycat site from borrowing a real company's account number. The business page has tabs for trading names and domain names. The brand you are using, or the exact web address in your browser, should appear on one of them. If the brand is the company name itself, the licence page is enough.

The three brands we reviewed show each kind of link:

• Trading name. bet365's casino licence is held by Hillside (UK Gaming) ENC, and the trading names tab lists bet365 as active.^[4]
• Company name. LeoVegas Gaming PLC holds its own licence. Its trading names tab says "No trading names have been recorded for this business", which is normal when the brand and the company share a name.^[5]
• Domain name. Blue Rock Managed Services Limited lists www.mrgreen.co.uk under domain names, marked "White Label", with no trading names recorded.^[6]

Each brand's full record is in our reviews, starting with the Mr Green licence review, the hardest of the three to trace.

Step 5: check for regulatory action

The public register also has a separate list of regulatory actions and public statements.^[1] Search it for the company name you found in step 2, not the brand. A past penalty does not mean a site is unsafe today, but it tells you which rules the business has broken before and what it was required to change.

Mistakes that lead to the wrong answer

• Stopping at the first search result. A brand search can return an old company with a surrendered licence. Mr Green Limited's casino licence, for example, ended on 28 October 2024, but the brand's UK domain is now listed under another company's active licence.^[7]
• Treating an empty trading-names tab as "unlicensed". It only means no separate brand name is recorded.
• Checking the brand but not the address. A licence covers the domains listed against it. An unfamiliar address using a famous brand is not covered just because the brand is.
• Accepting a foreign licence. A licence from another regulator does not allow a site to serve players in Great Britain.

What a licence does and does not promise

An active licence means the site must follow GB rules: ID checks before you gamble, slot stakes capped at £5 (or £2 if you are 18 to 24) and bonus wagering capped at 10 times. Our guide to UK online slot stake limits covers how the stake rules work. A licence does not promise good service, fast withdrawals or that you will win. It gives you rules the operator must follow and a regulator that can enforce them.
