How We Rate Online Casinos

CasinoUK is your go-to one-stop-shop for honest online casinos reviews. We regularly review, update and scrutinise the most trustworthy casinos available to players in the UK. But any review system needs to be fair to all, enabling you to make direct comparisons between the many hundreds of online casinos vying for your attention. So how exactly do we cut the wheat from the chaff, and what differentiates a 5-star casino from one that only gets, say, two or three? Well, our star rating system and the structure of our reviews have been honed to provide you with the most comprehensive evaluation possible, so that you can visit one of our recommended casinos safe in the knowledge that you know exactly what to expect.

First and foremost, we consider the relative merits of the welcome offer given to new players. Are there any free spins or bonus spins given out simply for registering a new account? Do these come with wagering requirements, and are they fair or exploitative?

Then, once a player has made a first deposit, are they entitled to more spins, or a percentage bonus? We ask questions about every aspect of these offers to ensure that you get the best deal possible. For example, some online casinos in the UK may offer deposit bonuses worth hundreds, but may require that you make three or four deposits in order to unlock the maximum amount. Others may offer less but couple that with amazingly low wagering requirements. We help you see through the marketing and work out what type of welcome offer is best for you.

Choice of Games

Casinos generally get their games from providers, but that doesn’t mean that all casinos are created equal. Some may have exclusive deals with providers to get access to new games before everyone else. Other casinos may avoid the bigger providers and go with a quirkier games selection from plucky upstarts or indie developers. Whereas, some casinos try to offer as many games as possible, often seeming to eschew any sense of quality over quantity. Therefore, we evaluate not only the amount of games available, but also the range, quality and exclusive deals offered by each casino.

Design & Usability

There’s no point in being excited about playing your favourite games if the casino offering them is riddled with bugs or has such bad design that it becomes frustrating navigating your way round. An online casino should not only look pretty but also be functional, solid and reliable, especially when it comes to more important matters such as making a deposit or withdrawing your winnings.

Customer Support

Sometimes it’s vital to speak to a real-life human being. There may be a problem with your account, or you might have a question that isn’t covered by the site’s FAQs or maybe you simply want to request that your chosen casino gets your favourite game. We anonymously contact each casino’s customer support team to ensure that they give great service. We also weigh up the amount of contact options (phone, email, live chat, post, for example) and how easy it is to contact someone in the middle of the night. After all, no one likes waiting around when you’re on a hot streak.

Other Considerations

These are just some of the things we consider when providing each casino’s rating. And we also return again and again to ensure that all our information is bang up to date. All to ensure that you can trust CasinoUK to find your perfect online casino in the UK.
