Choose the Best UK Online Casino – FAQs

Yes, gambling online in the UK is completely legal. All licensed UK online casinos are regulated by the UK Gambling Commission. To receive and retain a gambling license, each online casino in the UK must adhere to strict policies and guidelines as well as provide a safe, reliable, and fair gambling experience to all UK players.

How Do We Test UK Online Casinos?

We have compiled a list of more than 130+ UK online casinos. To be considered in our UK online casino list, the UK casino must hold an active license.

Beyond being a licensed UK online casino, we also considered the brand names which are most established and therefore, have the largest responsibilities to its players. From there, we began setting out to test each of these UK online casinos based on categories, topics, and questions we believe UK players care about — or should care about, at least!

Below are the main test categories we used to review and rate each UK online casino.

UK Casino Bonus and Promotions Tests:

  • First Deposit Bonus Test
    We calculated how much actual money you should expect to receive from a casino bonus on your first deposit after satisfying all wagering requirements.
  • No Deposit Bonus Test
    If the UK online casino offered a no deposit bonus, we measured how much actual money you would receive from that bonus if you satisfied all the playthrough requirements.

UK Casino Player Support Tests

  • Email Support Test
    We emailed every UK online casino with 10 questions and measured whether they responded and how long it took them to answer.
  • Live Chat Support Test
    We collected any information about live chat and its operating hours from the UK casino support pages.

UK Online Casino Player Experience Tests

  • Casino Game Library and Slots Selection Test
    We counted the number of casino games available from each UK online casino as well as the game types in each casino’s portfolio.
  • Website Speed Test
    We tested the load times across several important casino pages and averaged all the results to calculate how quickly each casino is.

Based on the result in each test, every casino was rewarded 1-5 stars. Jump to full test score card.

When all tests where done, we calculated an average and total score for every online casino in the United Kingdom, to then build an unbiased ranking system. This combination of stars and ranking helps us provide you with an objective view of the best UK online casinos.
