Our team follows a 25-step review process to find the best casinos in the UK. Scroll down to learn which key areas we assess and why.

• Bonuses with fair terms and conditions

  Many casino bonuses have unfair terms and conditions, which make it almost impossible to withdraw any winnings. Therefore, we rank casinos that have bonuses with fair wagering requirements, high maximum win caps, and are eligible to use on games with a fair Return to Player (RTP) rate more highly.

• Game selection

  The average UK casino features about 1,000 real money games from 20 providers. But some have much more. We favour sites with thousands of slots, classic table games, and innovative live dealer titles – all from top providers like NetEnt, Play’n GO, and Evolution.

  Why? So you’ve always got a variety of high-quality games with big jackpots and high payout rates (96% and above) at your fingertips.

• Fast & secure payments

  Nobody likes waiting for their winnings – that’s why we rank sites higher if they process withdrawals instantly and offer fast payment methods like e-wallets. Additionally, we only recommend casinos that process deposits instantly and offer a variety of secure UK payment methods, such as PayPal, Apple Pay, and debit cards.

  
• Mobile experience

  Top UK casinos run just as smoothly on mobile as they do on desktop. That's why we test page load speed, menu usability, and whether it has a dedicated app so you can enjoy your favourite games on your smartphone or tablet without fuss. If a casino has issues with mobile performance, we won't recommend it.

  
• Reputation, licensing, and player safety

  Each of our recommended casinos holds a UK Gambling Commission licence and utilises SSL encryption to ensure fair play, secure transactions, and access to responsible gambling tools like deposit limits. We also consider whether a site uses third-party game testing from auditors like eCOGRA.

  
• Professional & responsive customer support

  The best online casinos make it easy to get help when you need it. That’s why we rate platforms on their contact options, response time, and the professionalism of their support teams. The better casinos perform in our tests, the higher we rank them.

  💡Expert insight: Our review team scored Pub Casino 4.5/5 for its customer support, thanks to a 24/7 live chat operated by friendly human agents (no chatbots here!), a response time of under 24 hours via email, and a phone line open from 7 am to midnight every day. If you want to join a casino with a responsive and helpful support team, look no further.

• Overall experience

  Along with checking games, bonuses, and safety, we evaluate the full player experience. That includes other key factors like sign-up time, how easy it is to find your favourite games, and how smoothly the site runs. Only sites that deliver across the board earn a spot on our list of the best casinos in the UK.
