All UK casinos listed above were tested and approved by Chief Editor Simon Rose. The ranking is based on UKGC legal casino requirements and was last updated on 22 Apr 2021.

If you want to play online casino games, then you will be faced with a tough choice between all the platforms available in the UK. To help you find the top online casino, we have thoroughly researched, reviewed and rated the biggest names in the UK industry with the aim to give you all the info you need about the top 10 online casinos in Great Britain.

But is there a solid foundation behind this ranking? Well, it is based on a minute examination, the details of which can be found in the online casino reviews database, where we have checked 85+ sites active in 2021. Meanwhile, all the separate criteria of our methodology are explained in detail in the rest of this article.

Casino Reviews: How We Compare Al Online Casino Sites in the UK

The purpose of Online-Casinos.com is to offer you a database with trusted online casino reviews where you can enjoy games of chance without any worries for scams. We check the licence, technical security and data protection of each casino site we review. Based on that, we maintain a ranking of the best real money casino sites where UK players can deposi. All our lists are updated regularly based on the latest developments in the UK casino industry, which we cover in the extensive news section which you can see below.

The Ten Criteria Behind Our Ranking of UK’s Best Online Casino Sites

In order for any operator to provide services to players in Great Britain, it must hold a valid licence issued by the Gambling Commission. This means that only sites with an active licence are included in our tests to determine the best UK online casinos. All recommended casino sites are checked, reviewed and ranked according to ten criteria.

While most UK players focus on the bonus info, there are a lot of other things which you only notice after registering. This is why each casino review examines the platform in detail, focusing on things that most players would miss at first glance. So, let us proceed to the 10 criteria we use to select the best online casinos in the UK:

Game Catalogue – The Best Online Casino Games List

This is the most important thing for most online casino fans out there. The game selection determines what we can play in our free time. You can find classics such as slots, roulette and blackjack at all reputable online casino sites.

They were the first classic games to be transferred to the best online casinos back in 1994, when the pioneering site was launched. However, many players are surprised by the plethora of options you can get nowadays. You can take a look at the definitive casino games list to see the most popular titles available online in the UK:


Slots, fruit machines, one-armed bandits, puggies – these classic casino games are considered the most popular gambling choice in the UK. You can find great variety in the dedicated online slot casinos, from retro slot machines to new 3D variants featuring popular movie characters.


Roulette games are another irreplacable part of the classic casino experience. American, European and French roulette are the main variants you can play online, and they should be featured at all of the best roulette casinos in both RNG and live versions.


The popular card game is one of the top picks for experienced casino players. While card counting is no longer possible, this is still the casino game with the highest Return to Player, and you can find favourable rules and exciting side bets at online blackjack casinos.


Featured in beloved movies like Casino Royale, this is widely considered to be one of the most competitive casino games. If you want to test your skills, then our verified online poker sites allow you to play against real players from the UK and abroad.

Video Poker

Most slot fans find video poker games to be a pleasant alternative. Jacks of Better is considered to be the basic variant of the game, but there are also versions with great payouts such as Double Bonus Poker and Deuces Wild.

Live Baccarat Game at the Best UK Online Casino Site Did You Know? What you can play in most baccarat casino sites is actually the North American variant of the game – Punto Banco!

Bingo & Keno

Bingo is immensely popular in Great Britain, particularly in England. Naturally, we pay attention to best bingo sites you can find on the web, though using another rating system. We also have experience with keno games, which are rising in popularity.

Scratch Cards

Online scratch cards – or scratchies – are one of the latest additions to most UK online casinos. While the odds might be worse, they offer chances for large payouts and big jackpots. You can usually find them in a seperate section with other instant win games.

When creating online casino reviews, the game catalogue is the first thing people look at. This is why we always check the number of games available online after registration. But is this the most important factor for good online casinos?

In our casino reviews UK, we tend to give a bigger weighting to the variety and quality of the titles. For instance, the best rated online casinos receive a higher score in our ratings if they offer online slots from more than one provider, with the proper mix between classic 3-reel games, new 5-reel video slots, jackpot slots, bonus slots, branded slots, and more.

Oftentimes, people would actually look for specific games and base their choice of UK casinos on that. It is hard to say which are the best casino online games in the UK, as there are new titles coming out constantly. Based on our own experience and the latest feedback from British players, we can offer you the top 3 top-rated casino games for 2021:

Casino: NetBet Software: NetEnt Top-Rated Slot for 2021 Simple gameplay, elegant graphics and rewarding bonus features Play Here!
Casino: PlayOJO Software: EvolutionBest Live Roulette Lightning Roulette offers a unique mix of modern graphic effects & real dealers Play Here!
Casino: Casino.com Software: Playtech Best Blackjack Payout The unique switch mechanic gives this multi-hand RNG blackjack the highest blackjack RTP Play Here!

On the other hand, many players are only looking for jackpot slots, or similar games offering a grand prize. In such cases, it is much more important that the best UK casino sites feature a large number of jackpots, rather than regular casino games. We try to apply specialised rankings. You can find a separate guide to the best jackpot slots, or simply see what’s on offer in the top-rated jackpot casino for 2021:

The Grand Ivy Casino
  • Game Selection: 1,300+ Casino Games
  • Jackpots: 30+ Jackpot Games
  • Payouts: 96.25% Average Casino RTP
  • Software: 20+ Software Providers
Rating 95/100 • Top Jackpot Casino •

On a general note, new casino sites tend to offer a better variety if you are looking for the latest casino games. However, established providers also freshen up their catalogues on a regular basis. Players look for new casino games because they often have superior graphics & fun bonus rounds; as a whole, adding new titles from a reputable provider is something quality casinos need to do to stay competitive.

Welcome Bonus – The Best Casino Offers Available in the UK

The casino welcome bonus is one of the most important factors for many online players. However, there are many bonus terms you need to be aware of. To help you out in this regard, we have created an overview page where we track all of the best casino bonuses in the UK with detailed data and playthrough analysis. Based on that, the most important casino bonus terms include:

The welcome bonus is an important boost to your game balance, as most UK casino sites are willing to match your first deposit or even double it. While most players are interested in the lump soon of cash you can get, there are many additional perks which can make the best online casinos offers more enticing. Cashback options, no deposit bonuses and free spins are other things you need to factor in when evaluating a bonus offer.

Our experience shows that for most players, the hardest part is to make sense of all the terms and this leads to a lot of problems after they have registered and claimed their welcome bonus. You need to consider your play style carefully – what casino games do you prefer, how much are you willing to deposit, do you plan to play intensely or over a longer period of time. Still, there are some common tells that would allow you to spot the best casinos in the UK based on bonuses:

Good Casino Bonuses
  • High Bonus Amount & Free Spins
  • Wagering of 30x or Below
  • Contribution of at Least 10% for Table Games
Bad Casino Bonuses
  • Bonus Validity Below 14 Days
  • Wagering Above 35x
  • Bonus Is Valid for Few Games Only

If you keep all those principles in mind when you do an online casino comparison, you will be able to recognise the top online casino UK deals – though you would still need to read through a lot of fine print in order to find all the terms. However, it is better to be safe than sorry, which is why we always pay extra attention to this step when creating our casino reviews.

Casino Payout – Always Check the Casino RTP

Return to Player (RTP) is often misunderstood or overlooked by players. It shows how much of all bets placed for each game are paid back to players – thus, it is known as casino payout rate, or just payouts. The higher the RTP, the lower the house edge – this means that better payout rates work to the player’s advantage. UK casinos are required to make this information available for players.

The RTP for each game is usually found in the game rules on the website for UK online casinos. Many operators also publish actual payout reports from independent testing agencies such as eCOGRA and GLI, detailing the actual percentage returned to players across specific game categories during a particular time period. This is something that shows which are the most trusted online casino options, as it is not a legal requirement. Based on that, in the following graph you can see the standard casino payouts based on game category:

Casino Game Payout Rates
Classic Slots 94.30 – 99.32%
Video Slots 84.30 – 98.60%
Roulette 92.11 – 98.65%
Blackjack 91.99 – 99.86%
Table Games 85.64 – 99.80%
Video Poker 94.30 – 99.59%
Scratch Cards 93.00 – 96.02%
Arcade Games 80.01 – 97.22%
Return to Player (%)

In accordance with RTP audit standards, all online casinos in the UK are obliged to provide you with accurate data about the RTP of the specific game you choose to play – though it can sometimes be hard to find exactly where it has been published.

This is why we try to collect as much information as possible and find the best online casino payouts you can get. Some players choose to hunt specific games, but our methodology focuses rather on determining the top casino sites based on average payouts.

Maybe you’re wondering how the payout percentages of games at the best casino websites compare to slots in land-based casinos? Well as a general rule, RTP rates in brick and mortar casinos are lower than at online casinos. The higher operating costs are the main reason, as they need to be covered by the reduced payouts. This means that theoretically, you can get the highest payout rates at English casino websites.

List of the Best Payout Online Casino Sites for 2021

British players can take advantage of the fact that all UK online casinos are subject to strict software checks and audits. As such, their payout rates are guaranteed. We collect online casino data based on officially published information from the providers, though you should keep in mind that it is updated on a yearly basis. Here are the latest rankings for the best online casino payouts in the UK:

If you want to find more details on the topic, you should refer to the detailed article about best payout online casino sites in the UK. Of course, you should keep in mind that even the best rated online casinos have payouts that are calculated based on average values. However, it varies greatly from game to game.

This means that some games offer a higher payout percentage than others. If you want to maximise your odds of winning, you will need to do some serious research – but luckily, payout percentage data should always be listed in the ruleset of each game within the UK casinos. Some data for the highest RTP rates can also be found in the casino game reviews available on this site as well as in our top online casino reviews.

Casino Software – Which Are the Most Popular Providers for UK Players?

UK casino sites do not program the games featured on their sites themselves. Instead, they are supplied by a software development company, which can sometimes be responsible for maintaining the whole platform. For that reason, most UK players look for specific casino software brands when choosing their games.

The reasons for that may vary greatly between the top casino sites. Most of the bigger providers offer a distinct style in their graphics, themes and bonus rounds, so many people choose based on gameplay reasons, while others get used to the volatility and payout rates of the games. We have already spoken in length about this topic in our casino software guide, and based on the findings there, in the following table you can see an online casino comparison of the game selections available from the top UK casino software brands:

Software Provider Online Slots Roulette Tables Blackjack Variants Live Dealer Tables Most Popular UK Game
Playtech 200 19 14 60 Gladiator
Microgaming 456 8 44 Mega Moolah
NetEnt 124 9 11 9 Starburst
Play´n GO 120 14 14 Book of Dead
Evolution 20+ 25+ 60+ Lightning Roulette

So, what is essential in terms of the casino software and website? For starters, the software needs to be user-friendly, intuitive and easy to navigate. What’s more, it needs to be stable and reliable; there’s nothing more frustrating than games crashing regularly. It’s also appealing to experience slick graphics, and contemporary design, along with quick loading times at the most reliable online casinos.

Access to useful information is also important. We assessed how easy it was to search on the UK online casinos and find info about bonus terms, payout rates and deposit fees. The best casino sites are ones that clearly list this info, rather than those where you had to read through pages and pages of terms and conditions to find the relevant details.

Good Casino Software
  • User-Friendly Interface – Easy to Play
  • Wide Variety of Games & Graphics
  • Mobile Compatibility for Android & iOS
Bad Casino Software
  • Long Loading Time
  • Unclear Rules or Menus
  • Lack of Transparent Data for Payouts

Most of the recommended online casinos featured on this platform offer a solid mix between established software providers and smaller up-and-coming studios which often provide more innovative and interesting games. While Microgaming casino sites are the most sought after on a universal basis, the latest trends show that many UK players are interested in our NetEnt casino list. The Scandinavian provider has been winning a lot of fans with quirky designs and fun gameplay, and their titles are highly sought after.

Casino Security and Player Safety Standards

You have probably heard the sad tales of players having the bad luck of playing at dodgy online casinos back in the day. Rogue casinos posed a threat to online gamblers’ safety with all manner of illegal practises. Luckily for English players, the strict legislation that was put in place after the first casino scams means that if you are from the UK, you only need to check if your chosen casino site holds all the necessary licences.

Therefore, as we wish to bring you only the best online casino reviews, ensuring that players have a fair environment to enjoy their passion for games of chance is imperative. When you are talking about safety and fairness, there are really three different areas that need to be covered. These are: encryption of data transfers, analysis of game outcomes, and responsible gambling. Take a look below where you will find all the most prominent organisations in each of these fields.

Casino Safety Audits and Partners UK Players Can Trust

These are independent organisations who run safety checks and security audits, and ensure that the responsible gambling principles are reflected on the casino site and in our casino reviews. If their logos are present on the platform where you want to register, you should consider them a badge of honour.

Data Safety and Encryption
  • RapidSSL
  • GoDaddy
  • Comodo
  • Thawte
  • DigiCert
  • Symantec
Casino RTP & Game Software Audits
  • eCOGRA
  • TST
  • GLI
  • BMM
  • iTechLabs
  • SQS
  • Quinel
  • NMi
  • Alderney
Responsible Gambling Support
  • GamCare
  • Gambling Therapy
  • Gamblers Anonymous
  • GambleAware

Establishing a secure connection between the players and the UK casinos is one of the most important factors when it comes to the matter of reliable remote gambling. As we already mentioned, these top rated online casinos need to handle sensitive information such as names, addresses and bank account details which makes them a prime target for unlawful and illegitimate actions by hackers and other ill-intentioned parties. Currently, all of our top 10 recommended online casinos use state of the art 256-bit SSL encryption so you can rest assured that all of your data is kept secure and away from prying eyes.

Moreover, the software used by top rated casinos has been tested by a number of independent organisations, the most renowned of which is the eCommerce Online Gaming Regulation and Assurance (eCOGRA). If you find their logo at the bottom part of a casino’s site that means that they have tested the Random Number Generator(RNG) of the featured games and have made sure that they are not rigged in any way, shape or form.

Speaking of organisations, there are also a number of industry associations like the Betting and Gaming Council and the Industry Group for Responsible Gambling (IGRG), which aim to promote and improve socially responsible gambling in the UK.

In line with that, we are going to take a minute and discuss the importance of partnerships with organisations such as GamCare, BeGambleAware or Gambling Therapy. They are a clear sign that the best casino sites are socially responsible and are willing to participate in the fight against problem gambling and gambling addictions. Thanks to them, there are 24/7 helplines available to anyone in need. We believe that the best casino reviews are those that look at an operator’s whole package, including its commitment to player protection.

Licensed UK Casino Guide - How to Recognise Top Operators

All in all, it is quite easy to check whether a particular online casino, whether it is part of a massive network of sites or one of the many independent casino sites, is a great place for you to enjoy some games. Simply look for the important logos at the bottom of the page or do a quick search at the UKGC website. You can also find the information in all of our online casino reviews UK.

Mobile Casino App Performance Reviews – Best Casino Sites for Android & iOS

Without a shadow of a doubt, mobile devices of all sorts have become an integral part of our daily lives over the last decade. Thanks to the constantly advancing technologies, most people nowadays walk around with mini-computers in their pockets. For gamblers, this means they can now take their favourite online casino with them anywhere they go – as long as there is a stable internet connection.

The best mobile casinos have been optimised so well, that you are not going to notice any difference in performance when comparing it to playing the best UK casino on your desktop or laptop at home. Based on all the checks we ran during our UK casino reviews, here the best mobile casino app available in the UK for 2021:

Bonus betting limits: slots - £5 all other games – 10% of bonus amount.

As you can see, our top casino app is available on both Android and iOS devices. Our practise shows that most of the top online casinos are fully compatible with all mobile devices, as our list of iPhone casinos and Android casino sites has largely the same operators producing the best apps for UK players.

The latest research for our UK casino reviews shows that more than 70% of online gambling is now taking place on mobile devices. As a result, all major software developers design their new titles with mobile compatibility in mind. And when it comes to the player-favourite titles from the past, you can rest assured as most of them have been redeveloped so that they can run well on the go. In the following table, you are going to find the criteria to distinguish good mobile casinos from the rest.

Good Mobile Casino Apps
  • Many Compatible Slots & Table Games
  • Mobile Stream of Live Casino Games
  • Touchscreen-Friendly Interface
Bad Mobile Casino Apps
  • Slow Loading Times
  • Missing or Incompatible Games
  • Issues with Mobile Operating Systems

After explaining how the best online casino reviews cover the various facets of mobile casinos it is now time for our to tackle yet another phenomenon of online gaming – the live casinos. Make sure that you read our next section as we are going to introduce you to the world of live-dealer games and give you the top casino websites for real dealer games.

Live Casino Platform – Which Are the Best Real Dealer Games for the UK?

The live casinos are one of the greatest innovations in the field of remote gambling. It is the perfect marriage between the hustle and bustle of real dealer casinos, and the comfort of playing from your home. Moreover, thanks to the fast internet technologies of the last few years players are now treated with real-time high definition video that makes for a realistic experience. If you’d like to learn more, you can check our guide to the best live online casinos in the UK.

The Best Live Casino Games

In this exclusive live casino video you can see how real-dealer games work. Fans of live casino games have a vast choice of titles including different variants of live roulette, live blackjack, live baccarat, live casino poker, wheel of fortune, and others. You should keep in mind that each live casino site offers a different number of tables with varying betting limits. Of course, you should also check the ruleset and the language of the dealer too, but for most UK players the most important thing is whether they can play with low stakes or high stakes.

In the last couple of years, Evolution have been the go-to live casino software developer in the field of real-dealer games. They are completely dominating the industry, and all of the casino reviews we write, thanks to the high quality of their products. That being said, other big brands like NetEnt, Playtech or Microgaming are also producing good games. If you test a number of high-quality casinos, you will notice that those are the most common providers.

In addition to the game selection and software quality, there are other factors that should be taken into consideration. The betting limits, for example, should be appropriate for placing both high and low stakes. The dealers are yet another important factor. They should have perfect knowledge of the rules, speak fluent English and be charismatic. In the next table, you can find the other things that could affect the online casino ratings of any live site.

The Top Live Casinos Have:
  • Real Dealers Who Speak English Fluently
  • Good Live-Stream Quality with Fast Speed
  • Tables Suitable for Fans of Low Stakes & High Stakes
Bad Live Casino Sites Have:
  • Unsuitable Opening Times for the Tables
  • Casino Bonuses You Cannot Use on Live Games
  • Bad Streaming Quality

One last thing that you have to keep in mind is that if you want to have the full proper live casino experience at the best UK casino, you will have to play for real money. In order to do that, however, you must first learn how to make deposits and claim bonuses. We will give you some details about the top online casino practices in our next section.

Payment Methods: Fast Online Casino Deposits & Withdrawals

If you don’t make a deposit at the casino, you are limited to playing only free demo games through your account – unless, of course, you have chosen to claim one of the no deposit casino bonuses available with some operators. Unfortunately, online casino deposits with credit cards were banned after 14/04/20 in all of the UK – but you can still use a debit card or switch to an alternative accepted at casinos.

Most English gamblers prefer to use different eWallets, which explains why PayPal casino sites are among the most sought after. Still, there are plenty of other options you will be able to use at UK online casinos. You can read more in our guide to fast casino withdrawals. In the table below, you can see information about all casino payment methods accepted in the UK for 2021:

Many UK players actually choose online casinos based on the deposit and withdrawal methods which are available. Security, low fees and fast transactions are the main things they are looking for – and of course, sometimes there are certain casino bonuses which require a specific deposit method. For the more experienced online gamblers out there, fast payouts are one of the main priorities.

However, casino players need to keep in mind that even if a payment method offers fast transactions, most online casinos have their own internal security protocols and checks. These can sometimes change the situation – but in the next section, you can see a few quick guidelines we use for our casino reviews that will also help you to identify good and bad payment methods.

Good Casino Payment Method Choice
  • Fast Deposits and Withdrawals
  • Low Transaction Fees
  • Low Minimum Deposit Requirement
Bad Casino Payment Choice
  • Long Transaction Times
  • High Limit for the Minimum Deposit
  • Transaction Fees over 2.5%

If you feel confident you can make a casino deposit now, you should focus on choosing the best possible operator from our casino reviews – in that regard, we hope that our top ten online casinos ranking will also be of some use to you. However, you should still remember to research the internal policy of the online casino of your choice carefully. If you ever have any issues with casino payments, then a reliable customer support service is invaluable, especially if the casino is based in a different timezone. Naturally, this will be the next criteria which we will cover on our list.

Customer Support – Opening Times, Languages & Quality

Those of you who have no previous online casino experience will be delighted to find out that all venues featured on this website have great customer support. This is a part of the remote gaming experience that is often neglected in other casino reviews but can be of immense importance. Knowing that you can easily contact an expert to help you with any issues can really make the difference between a good and bad experience even at the top online casinos.

Casino Contact Method Availability at Online Casinos Response Time Best Suited For
☎️ Telephone Common Up to 5 Minutes Simple questions which can be answered quickly
📧 E-Mail/Contact Form Common Up to 24 Hours Complex Problems, especially if you need to attach documents or screenshots
👩‍⚕️ Live Chat Common Up to 3 Minutes All manner of questions which don’t require sending documents
💬 Messenger Rare Up to 5 Minutes Simple questions with short answers
🌐 Social Networks Rare Up to 48 Hours Feedback, suggestions for the casino

From the table above you can see all the different methods of contact that can be used to get in touch with the customer support experts at your chosen best internet casino. Having the option to chose between all of them is a great advantage through the most important and the ones that people use the most are the live chat, telephone hotline and email. This is why we do our best only to recommend the online casinos which offer them.

Good Casino Customer Support Should Offer:
  • Native English Speakers
  • Available 24/7
Common Casino Customer Support Issues Are:
  • Long Response Times
  • Badly Trained Operators

Another important factor in our online casino reviews is the customer support working hours. The best UK-based online casino should have customer support specialists available 24/7. Unfortunately, there are still venues where you can only get in touch with them during the workday. Whether that is a dealbreaker or not is up to you to decide. In case it is, however, you can always check out our list of the best British online casino sites as they all feature a 24/7 customer support.

The UK-based online casinos with the best features pride themselves on unique traits and achievements, which should be considered every time a site is rated. The casino awards are often overlooked by players, but they are an important sign. A good number of accolades usually hint at an internationally acclaimed operator which has passed the necessary regulation checks and can perform at an outstanding level.

Moreover, awards are a sign that bespeaks a quality casino, able to ensure user satisfaction. We always keep an eye out for the stamps of approval of third parties and awards won at international forums such as ICE London, when writing our online casino reviews.

Another sign for good casino sites for the UK can be the number of games in their catalogues. On many occasions I’ve seen selections of up to 1000+ titles (a good example are the best Playtech casinos). Furthermore, quality online casinos would allow you to try the games for free – something which is rarely possible in land-based venues. As a whole, there are a lot of advantages to internet casinos compared to their brick-and-mortar counterparts, which you can see in the graph below.

Comparison of Land-Based and Online Casinos

As you can see, our preference as casino players is towards the online platforms which offer many advantages compared to the classical variants. However, the one thing even the top online casinos can’t match is the bustling atmosphere of their land-based counterparts, which many people can afford to see only in movies. There is a hope that this will be remedied with the development of virtual reality technology, which should make the atmosphere of the casino saloon even more accessible.

All commercial gambling venues in the UK are legal and have been for the past 60 years. Nowadays, UK casinos have even become a major part of the country’s economy. Casino games, poker, sports betting, bingo, lottery, raffles, flipping coins and most other games of chance that one can think of are fully legal in the whole of Britain. Brits have access to a wide variety of the best online gambling sites available worldwide.

That being said, many major changes to UK casinos have taken place since commercial gambling became legal with the 1961 Gambling Act. One such example is the rise of online casinos and sports betting shops in the last two decades. They are considered as one of the most significant advances in the field, as they have made casino games easily accessible and widely available. As a result, now more than 40% of all betting activities take place on the internet. Down below, you can find a timeline marking the key events in the history of casino regulations in the United Kingdom.

History of UK Casino Laws & Policies
  • Gambling Act of 1960 The 1960 Gambling Act was the first major step towards creating and establishing the British gambling industry. What it did was to allow commercial bingo halls to open doors across the whole country.
  • Legal Sports Betting In the following year, the UK government also legalised sports betting. As a result, over 10,000 betting shops opened their doors to the public in the first 6 months.
  • Betting Shops Modernised Almost 20 years after they were first legalised, betting shops were allowed to introduce seating spaces, TVs and refreshments. This greatly improved the overall players’ experience, thus increasing the number of visitors.
  • Betting and Gambling Duties Act of 1981 As you could probably imagine, the 1960 Gambling Act did not tackle any questions related to remote gambling, as the internet wasn’t a thing at the time. That changed with the Betting and Gambling Duties Act of 1981, which helped lay out the main rules and restrictions of offshore gambling.
  • 2005 Gambling Act The 2005 Gambling Act brought the biggest reforms that the UK casino industry has ever experienced. All legal online casino sites had to implement a series of changes to keep their licence. The emphasis was put on preventing crimes such as underage gambling, identity theft and financial scams.
  • Licensing and Advertising Act of 2014 The last big update took place in 2014 when a decision was taken that all remote gaming venues that wish to provide their services to British citizens must have an up-to-date licence from the United Kingdom Gambling Commission.
  • UK Gambling Commission 2015 was the year when the United Kingdom Gambling Commission started operating. It is an independent, non-departmental organisation, which receives funding from the UK Department of Culture, Media and Sport.
  • Gambling Tax Increase The spike in online gambling in the UK lead to an increase of Remote Gambling Taxes from 15% to 21%, severely raising the bar for any new entrants on the internet casino market. The official UK Government proposal stated that the tax raise would come in effect on 1 October 2019.
  • Reduction of Max Offline Bet The UK Government announced that the maximum bet you can place on fixed-odds betting terminals will be reduced from £100 to £2. The decision was attributed to problem gambling concerns, and came amid huge unrest about the future of the casino industry following Brexit.
  • Credit Card Casino Payments Ban In the end of 2019 it was announced that credit cards will no longer be an accepted payment method at online casinos and betting sites. The UKGC stated that the measure would come into effect on April 14, 2020.

In the last couple of years, there have been many speculations about the prospect of Brexit and how it would affect online casinos in the United Kingdom. Experts in the field, however, are unanimous that the casino sector is unlikely to be affected by any changes related to Brexit. They believe that, because of their major role in the island’s economy, the British government is going to do its best to protect online casinos.

Of course, it is impossible to be entirely sure what the next few years are going to bring – but we can safely assume that at this stage, online casinos will remain legal in all regions of the UK. The obvious exception is Northern Ireland, which follows different legislation under the Betting, Gaming, Lotteries & Amusements Order of 1985 – however, since the current framework is quite outdated, there are concrete steps for updating casino laws there.

Regions with Legal Online Casinos in the United Kingdom
  • England
  • Scotland
  • Northern Ireland
  • Wales
  • North East
  • North West
  • Yorkshire and the Humber
  • West Midlands
  • East Midlands
  • South West
  • South East
  • East of England
  • Greater London

At this point of time, the most important thing is to always check if the casino site where you wish to register holds a valid UKGC licence. On the other hand, if you are still a fan of land-based games, you can always refer to our map of the best local casinos in the UK where you will be able to find licensed venues in your area. There will not be any changes unless you are from a region that followed different casino regulations before Brexit too.

As we already mentioned, the Gambling Commission is an independent regulatory body whose job is to make the British casino market the best and fairest environment that it could be. One of the Commission’s main tasks is to ensure that all UK casinos take good care of their customers and do their best to prevent any cases of money laundering, fraud or theft.

A prime example of their work and the constant advances made are the recently released rules regarding age and ID verification at online casinos. Until the second half of 2019, remote gaming venues had up to 72 hours to verify the identity of newly registered players. In that time, customers were only denied the ability to withdraw funds. The Commission, however, believed that it wasn’t enough and that more steps had to be taken in order to prevent underage gambling. As a result, the new legislation states that until a player’s age and ID are verified, he or she will not be allowed to deposit funds or have access to any of the casino games, even if they are free to play. This is just one of the most recent examples, a full list of which you can find at the website of the UKGC.

As you can clearly see, playing at English casinos with a licence from the United Kingdom Gambling Commission is the best bet that British players have. It presents a reliable and fair environment where you don’t need to worry about anything and can instead enjoy the fun of online games. Every site we recommend in our online casino reviews holds a licence. To spare you some time and make your lives easier we have compiled a list of recommended online casinos with an active UKGC licence:

List of Licenced Online Casinos

All companies with entries in the trusted online casino list should be well familiar to the British player. Reputation is an important factor, but only if the operator has passed all the necessary checks. The strict security standards imposed by the requirements of the UKGC for issuing a licence to UK casinos are good news for all online gamblers.

If you are looking for other legit online casinos, then you can read our guide to legal and trustworthy sites in the UK for other options as well as a full discussion of what operators should offer these days.

Other Licences for Online Casinos

Even though a licence from the UKGC is the best sign that online casinos are socially responsible and take good care of their players, there are a few other licensing organisations which audit internet casinos worldwide. These might be useful for you if you need some extra security, or if you ever want to play at an online casino while outside of the UK.

The most recognisable ones are the Malta Gaming Authority, Curacao eGaming and Isle of Man Gambling Supervision Commission. These organisations have extensive experience in the field of casino gaming; some of them have been active for well over 60 years. All online casinos that have passed their inspections will have the logo listed in the footer of their websites – in other words, you just need to scroll to the bottom of the page to see if the site is licensed or not. To summarise, here are the most relevant online casino licences for audited operators:

  • Malta Gaming Authority
  • Curacao eGaming
  • Isle of Man GSC
  • Gambling Commission

Blacklisted Casinos You Should Avoid

As we are talking about licences, now is the perfect time to take a minute and discuss the question of safety while playing games online. As you could probably imagine, some scammers disguise themselves as legit online casinos in order to steal the personal or banking details of unsuspecting players. This is why it is imperative that you only play at UK online casinos which have obtained their licence from the abovementioned regulatory bodies.

Down below you will find a list showing blacklisted casinos for the UK market. What this means is that they have been accused of being unfair to their customers or that they do not have an active UK casino licence. Make sure that you don’t accidentally create an account with any of these providers!

We are going to do our best to update this list regularly so that you know which providers should be avoided. There are a lot of reasons UK casinos may end blacklisted, and not all of them are scam-related. However, for online casino players reputation is extremely important, so illicit practices should not be taken lightly. Even though some operators manage to revise their policies and clean their record, this happens extremely rarely and good results need to be shown over a very long period of time.

Requirements for Obtaining a Casino Licence in the UK

You can rest assured that all UK casino sites need to pass a number of tests to obtain a valid UKGC licence. This verifies that British players can register and deposit safely, and enjoy fair RTP. Take a closer look at the following infographic where we have listed the exact steps taken by the UKGC as well as by the other gambling authorities in Britain.

Preview of Infographic About Online UK Casino Licence Preview of Infographic About Online UK Casino Licence

Even though having the logo of a licensing organisation on a website is a solid proof of legitimacy, we still believe that you need to be better prepared so that you can easily recognise the dubious providers from the best casino sites. This is why we rely heavily on our own independent tests to filter out quality brands from risky operators when we are conducting our casino reviews.

Tips & Tricks for Playing at Real Money Online Casinos

I briefly mentioned the huge utility of demo-play as opposed to always having to put real money on the line in order to test a new game. That very advantageous feature of the operators on our UK online casino list is also available on the apps for mobile casino games. In many ways, the land-based casinos inconvenience players, albeit non-intentionally. In the following lines, we are going shed light on how to find your comfort range when it comes to betting limits.

Best Online Casinos for High Stakes/Low Stakes Players

There’s no accounting for such things as taste, but some players certainly have a liking for high-stakes action. If the stakes are high, that means players are betting big. Of course, that would imply the possible payout is quite big but is it worth it? Here’s the kicker, even if you are playing at say, the biggest online casino, there’s no guarantee that your bet of £20,000 will be approved if you don’t check the betting limits.

That’s a high-roller bet right there – something characteristic for the big-time gamblers, or also called ‘whales’. If you want to bet big, you better make sure to sign with an operator that accepts big bets. Your next step is to find a VIP table for live dealer games like blackjack, roulette, or baccarat. Some claim to have wagered five-figure bets at the certain NetEnt casino websites. Since the live dealer tables are the place to be for high-stakes enthusiasts, we want to assure you that Evolution’s platform is also capable of handling big bets.

On the other side of the spectrum lies low-stakes play. Luckily for those gamblers who are on a budget, there are a number of suitable operators on the list of best casinos online. We already established that most games are played for free so that you don’t have to risk losing while learning the ropes. What’s more important is that Roulette and slots can be played for pennies. Minimum bets are usually around 10p, though penny slots will allow you to spin with even less.

Payout Rates for Offline Bets

The payouts you can get playing slots are bigger for online gamblers than they are for those visiting land-based casinos in the UK. We already explained the reason behind that in our paragraph about the highest online casino payouts.

First of all, all gambling software needs to pass RNG checks by independent third-party agencies to even be considered compliant with the requirements of the UK Gambling Commission. iTechLabs is one such agency that is empowered with the right to certify the games which are deemed fair. Of course, land-based slot machines pass similar checks, as they are governed by RNG modules very similar to those of online slots – but the pre-programmed RTP rates are usually significantly lower.

On top of that, after a machine is emptied, all elements and engine are reset to their initial state, and that’s the worst nightmare for those waiting for a jackpot to finally drop. If you choose to play online, you gain quick access to hundreds of slots, some of which offer progressive jackpots.

That gives internet casino players the freedom to switch between several games of different RTP rates. In our estimation, the score is at least 3:0 in favour of playing at casinos online,, especially in the UK. Keep that in mind next time you are faced with the dilemma whether to play from home or not.
