Mostbet Casino review: not licensed in Great Britain

Mostbet is an international casino and sportsbook brand with no Gambling Commission licence, and it does not appear on the GB register under any trading name or domain. Third-party reviews describe it as running under a Curacao licence and list the United Kingdom among its restricted markets, so it is not a licensed option in Great Britain.

Mostbet's standing in Great Britain

The Commission's register files of 2 November 2026 contain no account, trading name or domain that includes "mostbet". Its licence text and restricted-country list are not confirmed from the operator itself, so the safe reading is simple: treat Mostbet as unlicensed for Great Britain. The rest of this Mostbet Casino review shows which GB rules that leaves out.

A casino and sportsbook outside UK rules

Brands that combine betting and casino play are tightly regulated when they hold a GB licence. Since 19 January 2026, a licensed operator may not run one bonus that requires play across different products, such as betting plus casino, and wagering may not exceed 10 times the bonus amount. Credit cards have been banned for gambling since 14 April 2020, including e-wallets funded by a credit card, and reverse withdrawals have been banned since 31 October 2021.

None of these rules binds a brand without a Commission licence. Nor does the GAMSTOP requirement, the £5 slot stake limit or the duty to use an approved ADR provider. Our guide to UK casino bonus rules in 2026 explains the licensed side in more detail.

What about a Mostbet app?

An app is held to the same licence position as the website. GB licensees must show their licence status in their app as well as on their site, with an account number you can search. An app from a brand with no register entry gives you no more protection than its website.

Checking any brand, and getting help

Before trusting any casino or betting brand, search its name, domain or account number on the register, as shown in how to check a casino's UK licence. The online casinos UK section lists only Commission licensees. Gambling is for adults aged 18 and over, and our responsible gambling page lists free support, including the National Gambling Helpline.
