Best UK Online Casinos

Every online slot site on this page has an online casino licence from the British Gambling Commission ensuring that they are regularly tested for fairness, security and a high level of customer service.

UK online slot players can use their VISA or MasterCard Credit and Debit card as well as a selection of eWallets (PayPal, Neteller and Skrill) to deposit and withdraw. If you are looking for anonymity then you can use a crytocurrency like Bitcoin.

When we review a UK Players Welcome Casino we are looking for:

Safe and Fair Games – All these casinos are licensed with the British Gambling Commission; and use UK friendly slot software such as Microgaming, Playtech and NetEnt.
Deposit and Withdrawal Options – UK players can easily deposit and withdraw winnings; playing in £.
Regular Promotions – that UK players can take part in.
Security – that your personal and financial data are safe and secure.
Customer Support – you can get help online when you need it, 24/7.

The British Gambling Commission was set up under the Gambling Act 2005 to regulate commercial gambling in Great Britain. In 2014 the Gambling (Licensing and Advertising) Act required any operator wishing to transact with, or advertise to, consumers in Britain to obtain an operating licence from the Gambling Commission. Any online casino that does not have a licence from the British Gambling Commission is acting illegally in the UK and you should not play at such a casino from the UK; Rest assured all of these UK online slot sites do have a licence from the British Gambling Commission.
