UK Casino reviews – Our online casinos reviews & ratings process

What do we look for in our real money casino reviews? Bonus spins, deposit bonus, max free spins winnings only? No, when we publish online casino reviews UK we always try to look at the casino site as a whole. Not just focus on one thing. This allows us to give a proper online casino rating.

Licence and website

UK casino sites provide licence details at the bottom of their website

Real money UK online casinos are regulated. This means that not every online casino can just go online and start accepting customers from the UK. Online casinos that have a valid licence from the UK Gambling commission are allowed to operate real money games in the UK. Any site without this licence IS NOT legally allowed to operate in the UK. So you should only play at licensed UK casino sites.

All UK casinos that we review on our site have the proper UK licence. This means they are perfectly legal and legit sites to play at.

We do not list any UK online casino that does not have the British licence.

We always include information about the casino’s UK licence within our reviews. This gives you a bit more information about who owns and operates the site.

But you can find licence information at the bottom of the casino website itself – as shown in the example image above. You can also check whether the licence is valid from the Gambling Commission using the search function available on their site:

Check if gambling licence is valid

UK gambling commision website information

The casino site needs to be up to date. This means that it is quick and easy to navigate on the page and players can find their favorite casino games easily. Since most internet users nowadays use mobile devices more, we want to see great mobile casinos – not just a nice page on the desktop. Gambling sites sometimes even might have a dedicated app available for mobile users. In all our casino reviews, we explain how each website looks on all devices – along with the features you’ll be able to find.

Registration process (account verification)

Online casinos in the UK need to verify their customer before they are able to allow gambling for real money online to happen. Basically, this means they need to verify the name, age, and address. But do you always need to send in ID documents to prove your identity? Not always.

That’s because every site will try to be a no verification casino UK. This is when you get verified automatically straight away – with no documents required. This is the best outcome as you can start to play straight away.

But sometimes the account cannot be automatically verified – as shown here:

Our failed PokerStars verification

You are then requested to send ID documents such as proof of address and identity.

After you successfully provide the required documents, the account is verified and you can make real money payments in and out of the casino.

Confirmation that Unibet Casino UK account is verified

We make sure to explain the entire verification process within each casino review. So you’ll know exactly what kind of information and documents that you might be asked to provide. You can also get further information about this process on the casino’s website or by asking their customer support.

Payment methods and payouts

There are many different casino payment methods for UK players. It’s important for us that casinos offer a decent variety so you can choose your preferred method to deposit and withdraw real money.

But our best casino reviews have the most popular payment options for British players.

For example, a PayPal casino is a very popular choice in the UK at the moment and has been for years. PayPal offers fast, easy, and safe transactions that don’t share any payment information. Many British players also have an account ready to use. And if not, it’s very easy to set one up. So it’s pretty much the go to casino payment option. Basically all our best online casino reviews UK above have PayPal available to use.

Another type of site has also started becoming more popular with British players recently – the instant bank transfer casino. Although pretty much all online casinos have bank transfer available, only a few accept these payments instantly. That’s because this technology is quite new. And many players have started using it when available. So we are now updating our casino reviews based on if their bank transfer speeds are instant or not.

When it comes to payouts, pretty much all UK players want to play at casinos that payout quickly. In fact, slow withdrawals are one of the most common complaints that our readers mention in their real player casino reviews on our site. So we explain exactly how long each casino’s average withdrawal time is. From start to finish. Based on our own research. You can then decide if this is quick enough for you. If not, you can easily select a fast payout casino instead as an alternative.

Online casino bonus reviews

Most online casinos offer welcome bonuses to new British players who sign up. A lot of them look good on the face of it – big amounts of extra money, free spins, etc. But all of them have terms and conditions attached. It’s these terms that pretty much decide what the best first deposit bonus casino is – not how big the bonus is.

Our UK online casino reviews show you the significant terms and conditions of a bonus.

But we also do an honest breakdown of the terms and conditions to explain how likely it is that you’ll actually win real money from the bonus.

The most important part of an online casino bonus is the wagering requirements. This basically determines how difficult it will be to turn your bonus money into real cash. The lower the wagering, the better. In fact, many of our best online casino reviews listed above are actually a no wagering casino. At these sites, all wins are paid as real money straight away – making them very popular with British players. If a site has no wagering, you won’t be able to miss it in our review!

Other terms that are important include:

  • Qualifying deposit amount (the minimum you need to deposit of your own money)
  • Active bonus time (Bonus is active only for a certain amount of days. After that bonus funds expire)
  • Max bonus bet (Maximum bet is capped, usually 5 pounds per spin on slots)
  • Bonus excluded on certain games (eg. live casino games don’t contribute towards wagering)

The deposit bonus is commonly available in most casinos for new players. But some casinos offer free spins no deposit for new players too (these are sometimes known as bonus spins in the UK). This allows you to play slots without depositing any of your own money first. We will always make it clear what the casino is offering in full.

Online slots & games review

MrQ Casino's slots & games library

Casino sites mainly offer slots, as they are the most popular casino games at the moment. The best online casino has a wide selection of slots (multiple providers) and we aim to look that the biggest casino games are available to UK players.

Live casino games are very popular as well. Evolution Gaming is the biggest provider of live casino games and is hence commonly seen on most online casinos. Some casino sites might still have a better live casino product despite having the games from the same provider as the other online casino. Because Evolution Gaming sells dedicated live casino tables that are branded to a certain casino and cannot be accessed from another network. LeoVegas for example has its own branded live casino tables.

Customer support

A British casino needs to obviously have English support available. And all licensed operators do. Most of the top online casinos have support available around the clock (24/7) – but not all. If a site does not have 24/7 support then we will mention this in our casino review to let you know.

Usually, support is available via live chat but some casino sites also offer email and phone support. Some even still continue to accept letters sent by customers which is obviously the slowest method possible to get help.

Most casino sites also have an extensive FAQ section that provides answers quickly to the most common issues faced by players. So if the issue you’re facing can be seen as somewhat “generic”, you might want to first head to FAQ section to see, if there is a quick answer already available.

Responsible gambling

Best online casinos take responsible gambling seriously and offer players tools to control their gambling online. These tools can be:

  • Time limits on gambling
  • Deposit limits on gambling
  • Self-assessment tests (MrGreen has GreenGaming Tool)

The UK has a national gambling helpline (GamCare) available as well that helps people in need. If you or someone you know might have a gambling problem and needs help, you can get in touch by talking to them now.

Active development and innovation

It is important to keep up with the times and actively develop the casino product. Give users what they want. New slots are popping up left and right and players expect to be able to play them. An online casino needs to actively add new games to the selection and bring these games available to the users. Listen to the feedback and improve your product.

Online casino development - Unibet casino review

New casino reviews UK

We don’t add any casinos just because they have a UK licence. Instead, we are careful to list only those that we give at least a decent online casino review rating.

We want you to find good quality platforms where you’re more likely to have a good experience.

The downside is that we don’t have many brand new online casinos for you to try out. That’s because very few sites launch in the UK that we think are good enough. But that’s not to say it never happens.

Here are the most recent online casino reviews UK of new sites that we’ve published:

UK online casinoReview rating
Jackpot.com4.9 out of 5
Pink Casino4.6 out of 5
Duelz Casino4.9 out of 5

When good new casinos do launch, we follow the same process as above to properly review them. This is very important as players are often understandably cautious around depositing real money at new sites as they don’t have much reputation. So we make sure to test all the different aspects so you’ll know what to expect.

Our UK casino review update process

We don’t just review an online casino once and then forget about it. The casinos are constantly making changes to their sites which affects the player experience. So we regularly update our casino reviews to make sure they contain the latest information for you to read.

We make sure to focus on any negative changes as much as positive changes in our casino review updates.

We really want to see casino sites making changes that are beneficial for players. And this does happen quite regularly. For example, many UK sites change their bonuses to have fairer terms and conditions – because it’s what British players want. It’s also common for a casino to partner with more game providers after they launch. This expands the number of games available to play.

But there are also times when our casino review updates uncover negative changes. For example, we’ve noticed that some UK casinos have reduced the number of casino payment methods over the years. Usually this is not a good thing as we want players to have a variety of options. And occasionally, some new bonuses have harsher terms and conditions which is not attractive for players.

Whatever we find – good or bad – can affect our online casino ratings. If a casino improves their site then we give them a higher rating. But if the experience is worse than before then we will drop the rating.

So our list of best online casino reviews and ratings above are constantly changing based on the updates we do.

FAQ – Online casino reviews UK

Different people have different options on what is the “best online casino”, but we recommend MrQ. It has gotten good feedback from UK players and we enjoy playing there too. For more information about MrQ, read our MrQ casino review.

In the UK there are several trustworthy online casinos that have been in business for several years. A trustworthy online casino has transparent terms and conditions, a valid licence, and a clear owner that’s not hidden behind several companies. Most of the biggest online casinos are owned by stock-listed companies. We only review UK online casinos with a UK licence which allows them to legally operate in the UK.

We make sure to include a section on casino bonuses in each review we do. This section will explain what the welcome bonus is and the significant terms. We will also let you know about the bonus promotions for existing players if you decide to continue playing at the site.

We tell you what UK online slots are available within each casino review we do. We give a rough estimate of the total number of games you can play (as the exact amount is constantly changing). And we also explain what casino gaming software the casino has available – such as NetEnt, Play’n GO, Pragmatic Play, Microgaming, and more.

We recommend MrQ, which is the best online casino at the moment based on our experience and players’ casino reviews.

How we use our UK online casino reviews

Alongside reviewing online casinos, we regularly write articles and guides. These are written about a variety of gambling topics that are popular with our readers. The research we do when updating our online casino reviews also allows us to update these articles.

For example, we have an article about the top 20 online casinos UK at the moment. This article lists what we think are the top 20 sites for slots and games in the UK currently. Our review updates allow us to keep refreshing this list based on the latest information and ratings.

We sometimes find new features that players are actively looking for too. Like being able to deposit a minimum of £5. Most sites have a higher minimum deposit – like £10 or £20. But we’ve noticed that a few more sites have recently started allowing players to deposit a fiver. So we’ve been able to add more options to our £5 deposit casino UK list for players to consider.

Take a look at our most recent articles and guides here:
