UK Casino Reviews – Our online casino 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

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:

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 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 can allow gambling for real money online to happen. This means they need to verify the age and identity of each player.

When doing all our UK online casino reviews, we’ve needed to fill in a registration form using our personal details – such as name, date of birth, address, and more. This is non-negotiable. Make sure to provide the correct information when doing this.

But do you always need to send 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 are verified automatically with no documents being 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:

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.

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. Casinos must offer a decent variety so you can choose your preferred method to deposit and withdraw real money.

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

For example, PayPal is a very popular choice in the UK and has been for years. It offers fast, easy, and safe transactions that don’t share any sensitive information. We wrote articles for the Liverpool Echo and Manchester Evening News explaining why PayPal is the recommended payment method at UK online casinos:

You can view our list of PayPal casinos for the best options currently available.

Other e-wallets are also popular in Britain. One of the most widely used is MuchBetter where you can store money to deposit at a casino in seconds via their app. There are a lot of online casinos that accept MuchBetter too so you have a range of options to choose from. If you’re lucky enough to win while playing then any withdrawals are processed very quickly using this e-wallet.

There are other options besides e-wallets too. For example, one type of site that’s becoming more popular with British players recently is the instant bank transfer casino. Although pretty much all online casinos have bank transfers available, only a few accept these payments instantly. That’s because this technology is quite new and is usually powered using a service like Trustly. So we are now updating our casino reviews based on whether their bank transfer speeds are instant or not.

When it comes to payouts, pretty much all UK players want to play at casinos that pay out quickly. Slow withdrawals are one of the most common complaints within the real player casino reviews from our readers. So we test exactly how long a casino’s average withdrawal time is from start to finish to give you an idea of how long you’ll need to wait. Our research on this has been featured on Mirror.co.uk:

You can view the fastest payout casinos that we’ve tested to get access to your winnings quickly.

Online casino bonus reviews

Most online casinos offer UK casino bonuses to new British players who sign up. Many 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 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 determines how difficult it will be to turn your bonus money into real cash.

The lower the wagering, the better. Many of the best online casino reviews listed above are even no wagering casinos. These sites are very popular because all wins are paid out as real money straight away, as we explained in our article on WalesOnline:

Other important terms include:

• Qualifying deposit amount (the minimum you need to deposit 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 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

Casino sites mainly offer slots as they are the most popular casino games at the moment. The best online casinos have a wide selection of slots (from multiple providers). This allows them to offer the biggest casino games that 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

All licenced British casinos have English support available. 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 continue to accept letters sent by customers which is 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 the 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

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 need help, you can get in touch by talking to them now.

Active development and innovation

It’s important to keep up with the times and actively develop the casino product. The website should be updated regularly to make sure the design matches modern web development. MrQ has done a good job of this since launching in 2018, as shown in the image above.

Casinos should also 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 make these games available to the users. Listen to the feedback and improve your product.

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 are good enough. But that’s not to say it never happens.

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 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.

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 page lists the top 20 sites for slots and games in the UK currently. Our review updates allow us to keep refreshing these lists and articles based on the latest information and ratings.

Our research allows us to recommend casinos within different outlets too. For example, we explained in BirminghamLive how MrQ is one of the most popular casinos where you can deposit £10 at the moment:

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.

Why trust reviews by Casino Professor?

All the online casinos that we list on Casino Professor have been thoroughly tested first-hand by our UK team.

This allows us to create an overall rating that helps players compare all the options.

We only review casinos that are licensed by the UK Gambling Commission and are therefore legal in Great Britain. Although we earn commissions from the casinos, this does not impact how we rate each site. All the reviews are real and based completely on our own experiences.
