Since the start of NonUKCasinos, we’ve tested and compared thousands of casinos across 6 different countries. UK gambling scene is, of course, our focus market. New customers can rely on the online casinos that we recommend and us.

When we perform our online casino tests on real-money UK casinos, we check for a set of features that we find crucial for UK players:

  • Are the casino games offered to the players of the highest quality? We consider live casinos, slot games and table games.
  • Is the casino website nicely designed with natural navigation features? Satisfying mobile gambling experience is a must.
  • Are there ample payment methods available for secure and hassle-free online transactions? 
  • Deposit bonus for new customers: how good is the welcome offer? Max bonus?
  • How good is the customer support and how do they handle complaints?

Players are always suggested to spare some extra time to do some background research, before registering at any UK online casino site.

As a thumb rule, our reputed reviews will inform if a particular online casino is licensed in the UK or not. All legal UK online casinos will display the UKGC logo, placed on the footer of their website. The ones not on Gamstop will not be displaying the logo.

It’s up to the player to make the correct final decision for themselves.

Players will certainly have more confidence knowing that the casino where they are playing is a trusted one and licensed from any of the reputed gaming commissions. Remember that any casino site needs a license in order to operate. If not from the UK, then from Curacao or Malta.

Top Promotions at UK Online Casino Sites

No matter how competitive the online gambling industry has become, it is little wonder that the casino sites are always striving for better and more significant ways to entice new players.

The online casino scene is flooded with a plethora of casino bonuses and welcome offers! Nowadays, its the players market. However, not all bonuses offered are worth claiming, so before accepting any free spins or bonus funds, or even deposit bonus – set your standards.

With such a large number of great UK casino sites jumping on the bonus bandwagon, it is always recommended to do some prior research to find out what the casino is offering and how players would be benefitted from that specific offer.

When certain online casinos offer free spins or bonus money, the first thing to remember is that the free spins credits should be converted into real money before it has any monetary value. Before cashing out the bonus, players would have to meet wagering requirements.

Terms and conditions will always apply. As well as a minimum deposit, 35x wagering or that spins can only be used on selected games.

What to consider when joining a New Casino site

There is a number of factors that any player should consider before joining a casino site. For instance, wagering requirements.

ℹ️ Wagering requirements means the number of times the bonus amount should be wagered before players can successfully withdraw the amount to their bank account. 

Although the bonus wagering conditions would vary from one casino site to another, most of them are generally in the range of 25x to 40x plus the deposit amount.

To consider when joining a casino site

The bonus percentage might dictate how much slot games or any other casino game contributes towards wagering requirements. It is important to note that slots titles always carry a higher wagering percentage in comparison to table games, video poker and live dealer games.

House Edge is another crucial criteria that any players should not overlook while playing online casino. The term, also called RTP (Return to player) has a big impact on your online gambling experience.

If an online casino offers a house edge of 8% on their games, it means the operator is earning 8% profit from the winning of the player on average.

A lower house edge dictates more favourable odds for the player to win. When we choose the best online casino UK, RTP is a major variable. RTP is anyhow not set by the online casino but by the slot game providers. Meaning that the house edge is dependent on which game providers the casino site offers.

Live casino games however cannot be adjusted by the provider.

How to determine a Good UK Casino Site?

There are thousands of casino sites out there, but not all of them are reputable or trustworthy. Since all online casinos give you the chance to play for real money, you need to know that the sites you are visiting are legitimate and will payout your winnings. NonUKCasinos can help you identify the best, and most popular, online casinos in the UK.

We specialise in keeping you informed and up-to-date on what is happening in the UK gambling industry. We ensure that all the casino sites reviewed on our site are safe, secure and licensed in the UK, Malta or Curacao, and conform to the rules and regulations of the United Kingdom Gambling Commission.

If you are new to the world of UK online casinos or looking for a new casino site to join, you need to do your due diligence. To be safe, you should always look for legitimate online casinos with a history of accepting wagers and doing business with gamblers in the UK. 

Look at the site’s features and check out their customer service lines (call the number to confirm it is legitimate), certification and licensing information. Make sure that the bonus offer is legit by checking the terms and conditions before placing your first deposit.

UK based online casinos will display their licensing credentials on their site (usually at the bottom of their home page), and this will include their address, contact details and a license number issued by the UK Gambling Commission

Also, check out reviews written by other online gamblers and on reputable sites like NonUKCasinos to ensure that the online casino site you are visiting are legitimate and offer great user experience.

These give you the possibility to sort, filter and select some of the best casino websites based on parameters that our visitors have chosen.

There are, however, some aspects that are subjective and impossible for us to rate since it’s up to every single player to determine what they’re after. These online casino types are in a cluster of their own pretty much.

different casino websites
  • Gamification Casino Sites: The word “gamification” was the buzz among casino websites a couple of years ago. A gamification-casino is customarily focused and built around certain casino adventure features. It could be a “Wheel of Fortune” or a casino that is taking place in a fictive world. Gamification casinos used to offer a good variety of slot games. These are now however restricted in the UK.
  • Bonus Casino: The casino bonus websites usually are all about bonuses – it could be a 10 % cashback, free spins or weekly promotions for existing players. Good value casinos!
  • Design Casino Sites: Last year, almost all launched casinos went “all in” with the design. There was a lot of “pixel-perfect” websites released, and this was highly appreciated among the UK players.
  • Simple Casino Sites: The current trend is to make “simple casinos”. This means everything is lightning fast and focused on casino games. Everything should work seamlessly, including all payments, withdrawals and loading time.
  • Live Casinos: A Live casino is exactly what it sounds like, an online casino offering mostly casino games that include a live dealer. The perfect destination for any player that fancies table games, streamed from land-based casinos worldwide.
  • Mobile Casino: Players wager nowadays more on their mobile phones than using desktops. Mobile slots dominate player forums, and true gambling products will even offer casino apps. Game developers are also focusing more and more on the mobile experience.

So, basically, these different types are each and every casino websites own “USP” – Unique Selling Point – and it is up to you to pick what you fancy.

How to Find the Best Casino Online UK

When we rate the UK online casinos, we use several different variables to give our users an excellent review of the site. These are all aspects that you should take into consideration in order to find the right casino experience. On top of the website design and usability, having a fun theme is always a plus.

Any gamification options such as tournaments, or additional features such as constant casino bonuses, are also good incentives to keep on coming back to the casino site. Something that’s also overlooked is the importance of excellent customer support, which we always take into account.

It’s also imperative to think about the payment options available as we touched upon. Most online casinos will offer a range of different options, with deposits generally being instant.

As online gambling gets more popular each day in the UK, there is an increasing number of internet casinos popping up. While this is great in terms of having a ton to choose from, it might become overwhelming, especially for new players. Being able to find a good casino site is getting increasingly hard as players can’t differentiate between all the options available to them.

NonUKCasinos is here to help you find the best option for you. We have created this guide to help you figure out which of these top UK casinos suits you the best.

  • Design and usability on desktop & mobile
  • Choice of casino games (slots & live casino)
  • A good first deposit bonus offer
  • Gamification is a plus
  • Excellent customer support
  • Choice of banking options
  • VIP programme for loyal players

Game Selection at Casino Sites

Since casino games is that big of an aspect, we believe that it’s worth digging a bit deeper into this topic. We’re talking about than just having a big selection. In order to be among the best online casinos in the business, you’ll need diversity and a wide variety. You don’t just want 1000s of slots! As a player, you want to be able to try different high-quality games. From live casino to video poker through to slot casino options.

It’s also essential to check out the game providers to ensure that the games offered are all of the best quality and operating under fair gaming rules.

  • Mobile games
  • Live dealer options
  • Roulette games
  • Blackjack games
  • Slots games

Deposit Bonus Options

Most online casinos will offer a series of bonuses to boost your bankroll with bonus funds. Now, it’s all very well for a casino to offer a lucrative welcome bonus to new players, but genuinely great online casinos will provide something more than that.

For the best online casino experience, you will want to pick a casino that also offers additional bonuses to those players who remain loyal and stick around to keep playing. With this in mind, it’s a good idea to see if the site has a VIP or loyalty programme available, offering regular players more significant and better bonuses. Yet, a deposit bonus is often worth claiming s long as the terms and conditions are decent.

  • Free spins
  • Live casino bonus
  • 10% cashback or more
  • Deposit bonus on 1-5 first deposits
  • Bonus amount upon registration (no deposit bonus)

Is there a Legit Online Casino Site?

There are plenty of legitimate online casinos in the UK. To be able to offer their services to UK players, casinos within the United Kingdom must abide by specific rules and regulations. They must also hold a licence from the UK Gambling Commission, which is one of the strictest jurisdictions in the world. Having a licence from them means that casino has to provide protection for its players, ensure their casino games are fair and even offer responsible gaming options on top of it all.

If you are unsure whether a casino site is legitimate or not, it’s a simple process to check their license. Online casinos are required to display their licence on their webpage; usually, it can be found at the bottom of the header. If there is no licensing information, then it’s a sign that this casino might not be all it says it is.

  • Casinos in the UK must be licenced
  • Licences can be found at the bottom of the leading casino page
  • The UKGC is one of the strictest jurisdictions

Top-level Support at the Casino Sites

As we touched upon, one of the crucial factors that turn a casino site into a top-class one is the customer support. Surprisingly, this aspect is often overlooked by players. While you may feel that the casino works well and offers a robust and consistent platform, this might not always be the case.

With this in mind, you will need to ensure that there is prompt customer support ready to help if ever an issue should arise. The best casino sites will have a live chat that’s manned throughout the week and around the clock.

With a live chat like this, you can get help within minutes and get back on track. It’s also helpful if online casinos offer an email support as well as having a phone support option. Most UK online casinos will also be upfront offering a comprehensive FAQ that saves you the hassle of getting in touch with their support team.

Which Games Have the Highest Winning Chance?

Once you’ve found the best online casino to play at, it is then time to find the best casino games to play. As many of you will know, casino games do not come with a 100% winning guarantee.

In fact, there is a house edge which means that, in general, everything falls in favour of the online casino. However, some games have a smaller house edge than others, which means you have a better chance of winning when you play them for an extended period of time.

One of the best game collections to play when you are online are video poker games. Unlike most casinos games that have a house edge of at least 2%, the house edge on video poker can actually totally disappear. Video poker is all about strategy, as is regular poker. So if you manage to hit on a perfect strategy, the house edge is wholly reduced and ends up swinging in your favour.

RTPs for games like this can end up above 100%, even reaching 100.7%, which makes them the games with the highest winning chance. Yet, slots remain the most played games in online casinos.

What Online Slots Payout the most?

Slots the most popular game to play online, and there are thousands of them. This means that you will have a lot of different choices made available to you. When it comes to payouts, though, it is the progressive jackpots such as Mega Moolah or Mega Fortune that pay out the big bucks. These slots continue to increase their jackpots as more people play. The jackpot slots simply continues to grow until someone finally wins it. But that is if you hit the jackpot.

There are plenty of other slots that can give you a great RTP rate ( return to player). New customers might prefer these slots as they will get you playing for quite some time as they often also are low volatile. The great RTP slots are often also used to convert bonus funds into real money. So next time you get a deposit bonus and bonus funds to use, why not try any of below-selected games with great RTP?

Old or New Casino Sites?

A final question that always seems to arise when looking for the best online casino is whether new casinos are better than those that are older and more established.

Older online casinos have the advantage of having created and maintained a reputation, usually showing their trustworthiness and reliability. They will offer a vast range of casino games too, all of which generally come from the best software providers. However, they aren’t always at the forefront of any new technologies or features, which is where more modern online casinos often have the edge.

New casinos can see what was successful and build on it. In this way, you will often find that more original sites have exciting themes and a lot of additional gamification features such as tournaments or in-play bonuses. New casino sites will also have a vast range of games and are likely to continue to add to it. They also offer some more lucrative bonuses as they strive to make themselves stand out in a world full of casinos. However, both new and old casino sites offer excellent gambling platforms.

Responsible gaming at the Best Casino Sites

A final aspect to consider when playing online is responsible gaming. For many of us, playing online is strictly a fun hobby, but for some, it can become overwhelming. Best UK online casinos recognise this issue and take steps to help players prevent it from getting that far, or offer support when the problem has arisen. For instance, some of the best casinos will provide support links so that struggling players can chat with someone in an attempt to help them overcome their gaming addiction.

Another important factor that online casinos will offer is the option to self exclude. Being able to self eliminate allows players to ban themselves from the online casino and its games for a specified period of time. This ban cannot be lifted until the end of the given period. In this way, players have the time to get help. Most casino sites will also enable players to keep track of the time spent playing, how much they have spent and lost, and other valuable data sets to keep them aware of their gaming habits. 

  • Self-exclusion
  • Keep track of time and money spent playing
  • Helplines provided
