Our Casino Evaluation & Review Methodology

Our approach to reviewing casinos is based on collecting and analysing all key information about each platform, including:

  • Licensing – we verify whether the casino holds a valid and reputable gambling licence.

  • Game Providers – number and names of software providers featured on the site.

  • Traffic & Popularity – monthly player traffic and overall site visits.

  • Bonuses & Promotions – welcome offers, ongoing bonuses, and special promotions.

  • Customer Support – quality of support service and availability of live chat.

  • Player Feedback – user reviews and ratings on external platforms.

  • Payments – available deposit and withdrawal methods, limits, and processing times.

This allows us to create objective, detailed and transparent reviews for every casino we list

How to Open an Account at a UK Online Casino

Opening an account and playing for real money in a UK casino is quite simple. You will need:

  • A real residential address in the UK

  • A mobile phone number

  • A valid email address

Steps:

  • Go to the casino’s website and fill out the registration form with your personal details.

  • After signing up, you must complete the KYC (Know Your Customer) verification process.

  • To verify your identity and address, you’ll need to send documents such as:

    • A utility bill or bank statement showing your physical UK address

    • A photo ID (passport, driving licence, or ID card)

Once verified, you can deposit money and start playing legally and safely at UK-licensed casinos.

UK Gambling Regulation & Licence Cost

Online casinos in the UK must be licensed by the UK Gambling Commission (UKGC) under the Gambling Act 2005. This licence guarantees legal operation, player protection and responsible gambling.

The cost depends on annual revenue (GGY):

  • Application fee starts from £4,224

  • Annual fee ranges from £4,199 to over £790,000

Only UKGC-licensed casinos are legally allowed to operate online in the UK.
