How We Compare the United Kingdom's Best Online Casino Sites
With so many online and mobile casinos in operation these days, and not all of them fantastic, it's crucial that you learn how to recognise the UK's very best and most worthwhile online casino sites so you can ignore the rest. With that in mind, here are some of the fool proof criteria our review team uses to test, rate and compare UK online casinos in an unbiased and fair way:
Safety and Fairness
Ensuring your personal well-being involves licensing, independent testing, technology and a commitment to responsible gambling.
Pick sites that give you wide choice and offer a good mix of games from the leading casino software providers.
Security, reliability, financial backing and innovation set the leading software providers apart from the pack.
For most people, bonuses are the most important feature when picking a casino. We can help you choose wisely.
Banking comes down to personal choice. Do you prefer Pay By Phone, Paypal or Credit Cards?
Best Mobile Casinos
Pick casinos that have a high quality mobile product and offer a seamless experience from desktop to mobile.
Live Dealer Games
Live dealer games are gaining in popularity. The quality of the experience varies, and we can help you to pick the best.
24/7 customer service should be non-negotiable and response turnaround time should be less than 24 hours regardless of your contact method of choice.
How Online Casinos Ensure Safety, Fairness and Security
It goes without saying that the online casinos we promote are 100% committed to the safety and security of their players, and always abide by the highest levels of fairness and honesty. However, if you don't have decades of experience in the online gambling industry the way we have, you may be curious as to how online casinos ensure safety, fairness and security.
The answer lies in where a casino is licensed and which independent online gaming industry auditing or 'watchdog' organisations and testing labs it is aligned with. You'll usually find this information at the bottom of a casino's homepage by way of seals and/or logos representing said organisations.
Here are the most common organisations and industry bodies:
UK Online Casino Licensing
Via its Gambling Commission, the UK has one of the most liberalised online gaming industries.
* Although other jurisdictions such as Malta, Isle of Man, Alderney and Gibraltar are reputable, we only list casinos licensed by the UKGC.
Independent Auditing Organisations and Testing Labs
|eCommerce and Online Gaming Regulation and Assurance is a UK-based online gaming regulatory body that conducts rigorous casino and game tests and facilitates dispute resolution for players of regulated online gambling sites.|
|For more than a quarter of a century Gaming Laboratories International has tested casino and lottery games for a wide variety of land, tribal and online casinos and lottery firms across the globe.|
|Since 1993 Technical Systems Testing has been a gold standard in the testing and auditing of online casino games for fairness. Part of GLI since 2010, TST also provides its services to land-based casinos.|
|Based in Australia, iTech Labs has tested and evaluated online casino, poker and betting games, facilities and platforms for over a decade, including RNG (random number generators) to ensure slots pay out as advertised.|
Responsible Gambling Organisations
Most premier online casinos are aligned with one or more non-profit responsible gambling organisations that provide free and confidential information, advice, support and counselling for the treatment and prevention of problem gambling. These include:
|A provider of free telephonic, online and in-person specialist counselling for anyone in the UK with a gambling problem, as well as their partners and family members.|
|Funded and run as an independent charity, UK-based BeGambleAware is a respected free information, advice and assistance provider to people with gambling problems.|

Learn More About Software Providers
We estimate there are over 100 casino software developers that are authorised by the UK Gambling Commission to license their games to UK operators.
This level of competition is staggering and has resulted in incredible innovations over the last few years from casino software pioneers like IGT, Microgaming and NetEnt (who pioneered 3rd licensing of branded slot games on their platform) and new kids on the block like Blueprint Gaming, High 5 games and Quickspin.
Many leading casino game firms that built their reputations on producing games for land-based casinos now also offer their games for online and mobile casinos including Novomatic, Ainsworth, Bally and SG.
Some of the most exciting game providers are those that specialise in one game category. Malta-based firm Yggdrassil, for instance, focuses solely on online slot games and to date has produced many visually stunning and worthwhile slot machine games with amazing bonus rounds.
Play 'n Go is another remote slot game specialist that has an incredible suite of bold, bright, entertaining and lucrative slots to choose from.
We suggest you try free spins as a way to familiarise yourself with the games and new software providers. You might even get lucky and boost your bank roll in the process!

Here are the three most common online casino customer care methods:
Most online casinos have one or more toll free telephone numbers you can call 24/7, which is handy if you're on the move and require immediate assistance.
Live Chat Support
