The Gambling Commission has issued several different types of licenses including ones for arcade games, remote and non-remote betting & casino operators, bingo, gambling software, online gaming machines, as well as lottery.
So, the best UK online sites hold a remote casino operating license and they are required to be socially responsible, by not accepting underage gamblers. In addition, the best UK casino websites do not accept problem gamblers who have previously self-excluded on GAMSTOP. All in all, UKGC-licensed online casinos have been thoroughly audited on essential aspects, such as fairness and financial transparency; so they manage to keep their standards high.
Are British casino sites safe?
A British online casino that holds a license issued by the UKGC is indeed safe; since the Gambling Commission does not grant licenses to operators that don’t take player protection seriously. More specifically, all licensed British casino sites use encryption technology so as to keep their players’ data & payment info secure and allow them to self-exclude at any time since they are compatible with GAMSTOP. Moreover, the software that all UK casino sites use is reliable and their games & slots are not rigged; since they are successfully tested by independent third-party organizations like eCogra. So a UKGC license is a clear sign that you are gambling on a legit casino site and not on a scam one. Plus, keep in mind that all winnings deriving from a regulated online British casino are tax-free.
How to deposit at United Kingdom online casinos
The UK is undoubtedly one of the leading economies in the world. Thus, you have uncountable options when it comes to how you’re going to deposit or withdraw your money on any of the best UK casino sites.

Advantages of UK licensed online casinos
All licensed UK online casino sites are fully compliant with the UKGC’s fair and transparent terms and practices. This actually means that, if you opt for a licensed casino in the UK; you can rest assured that its T&Cs, as well as its bonus terms, are well-reviewed by the Gambling Commission. So let’s take a closer look at all the benefits of regulated online casinos in Britain.
✔ Transparent terms: As of 7 May 2019, all online casinos which hold a license in Great Britain, are obliged to verify their players’ age before they allow them to gamble.

Plus, they clearly display the rules of each game and slot that they offer; along with the RTP.
✔ Player protection: All the licensed online casino sites UK offers take gambling addiction very seriously. Thus, as of 31 March 2020 they are obliged to participate in GAMSTOP (i.e. the self-exclusion scheme for the online gambling sector in Britain).

✔ Financial security: According to the UKGC’s provisions, all licensees should keep their business funds and their players’ funds in separate accounts.
