How we rank online casinos
Our online casino reviews are thorough and cover all the important bases. Here’s everything we consider before determining whether or not we’re happy to recommend a casino to you:
Safety & support
We check to ensure that sites are licensed and regulated by industry bodies such as the Gambling Commission (UKGC) and Malta Gaming Authority (MGA) to guarantee safe gambling. Casinos should also have reliable customer support options, preferably available 24/7 via live chat, phone and email.
Game selection & software
The best online casinos boast diverse game libraries featuring thousands of titles from leading software providers. We see if the games on offer cater to all players, from slots fans to live casino lovers, so you’re not stuck for something fun to play.
Bonuses & promos
Our top-rated sites have a range of generous casino bonuses, spanning exciting sign-up offers for new players and regular reload promotions for existing accounts. We also check that the wagering requirements and other T&Cs are fair and transparent.
Payment options
Our reviews focus on the banking options available at an online casino. We recommend sites supporting multiple popular payment methods, while allowing players to make instant deposits and fast withdrawals that ideally take no longer than 24 hours.
Mobile experience
With more players choosing to gamble while on the move, a great mobile site and/or app is a must-have for top casinos. The best mobile casinos offer the same games as available on desktop, with fast loading times and smooth gameplay on both iPhone and Android devices.

How to find the best online casinos
The obvious starting point to finding the best online casinos in the UK is reading our expert reviews to see which sites we love and why. However, if you come across a new casino in your own time, here are things to consider when deciding whether to sign up:
Always start with the licence. If the site is permitted to operate in the UK legally, it will be licensed and regulated by the Gambling Commission.
Check the games library. Variety and quantity are key, so see if you can get a feel for how many titles the casino offers, what game types they cover and which providers have produced them.
Read user reviews to see what existing players have to say about their experience at the casino.
Finally, check if the casino has won any industry awards, which is a good sign that it is a high-quality platform.
Online casinos to avoid
If you come across a site that meets the following criteria, we would recommend not signing up for an account and depositing money there:
Unclear licensing, limited security measures and a lack of customer support options.
Bonuses featuring highly restrictive T&Cs and wagering requirements.
Limited games selection featuring titles from lesser-known providers.
Slow withdrawal times and verification processes.
Low or bad ratings on customer review sites.
