Find the Best UK Online Casinos

We tested every UK online casino to find the best — here’s the results!

Nobody wants to gamble their real money at a bad online casino, so we searched for the best online casino in the UK. How do you find the top UK online casinos? It starts with looking at the most common questions and topics UK gamblers look for when choosing between online casinos in the UK.

  • Which UK online casino has the best casino bonus?
  • Are there any UK online casino no deposit bonuses available?
  • Which online casinos in the UK offer free spins no deposit?
  • What are the RTP for slot games at different UK online casinos?
  • Which online casino in the UK has the biggest library of casino games?
  • Which UK online casino has the best customer service?
  • What are the withdraw and deposit options for each online casino in the UK?
  • What UK online casino has the best user experience for players?

These UK casino questions and many others formed the foundation for different tests which we ran for each online casino in the UK.  We have tested all UK online casinos based on casino bonuses, no deposit promotions, website speed, number of slots, email support, and live chat support. See our list of the best and worst gambling sites in the UK below.

Choose the Best UK Online Casino – FAQs

Yes, gambling online in the UK is completely legal. All licensed UK online casinos are regulated by the UK Gambling Commission. To receive and retain a gambling license, each online casino in the UK must adhere to strict policies and guidelines as well as provide a safe, reliable, and fair gambling experience to all UK players.

To ensure that an online casino in the UK is safe and trustworthy, check that it has an active license from the UK Gambling Commission. Additionally, consider the technical safety of that casino by confirming that it has SSL encryption and that you understand the terms and conditions of that specific casino. Finally, read unbiased UK online casino reviews like the ones we provide here at Great.com.

UK online casinos offer a range of different game types including the most popular online casino game — slots.

UK online casinos offer several different types of casino bonuses and promotions for new and existing players. From no deposit bonuses, first deposit cashback offers, first deposit match bonuses, free spins, welcome bonuses, and other loyalty rewards — there is no shortage of casino bonuses available in the UK. Who has the best UK online casino bonus? You’ll have to read or UK casino bonus test results to find out!

Yes, many UK online casinos have mobile-friendly websites or a separate mobile app which can run a version of its online casino from any device — including tables or smartphones on iOS, Android, or other.

Every UK online casino has a multitude of banking and payment options for players looking to deposit or withdraw funds into and from their accounts. After registering at the online casino, you can deposit using:

Each UK online casino will have other or similar options for depositing and withdrawing funds. Keep in mind that the payment option as well as the casino’s conditions may affect processing times and transaction fees.

If you have a problem or complaint about an online casino in the UK, you should consider reaching out to the customer support department from that UK online casino to discuss the matter. If you’re unable to find a satisfactory resolution to your issue with that casino, consider filing a complaint with the Alternative Dispute Resolution (ADR) service which acts as an independent mediator between you and the UK casino. If you still have not found a resonable solution to your issue, you can reach out to the UK Gambling Commission to investigate and assist.

Part of the UK Gambling Commission’s job is to ensure the safety of players at its licensed UK casinos and with that comes a level of assurance in those online casino’s ability to protect the personal and financial information of its players. While any website is susceptible to hacking, all licensed UK online casinos use advanced measures like SSL to protect and secure the private information of its players. There are also strict privacy policies to keep your data and information away from third parties without your knowledge and consent.

How Do We Test UK Online Casinos?

We have compiled a list of more than 130+ UK online casinos. To be considered in our UK online casino list, the UK casino must hold an active license.

Beyond being a licensed UK online casino, we also considered the brand names which are most established and therefore, have the largest responsibilities to its players. From there, we began setting out to test each of these UK online casinos based on categories, topics, and questions we believe UK players care about — or should care about, at least!

Below are the main test categories we used to review and rate each UK online casino.

UK Casino Bonus and Promotions Tests:

  • First Deposit Bonus Test
    We calculated how much actual money you should expect to receive from a casino bonus on your first deposit after satisfying all wagering requirements.
  • No Deposit Bonus Test
    If the UK online casino offered a no deposit bonus, we measured how much actual money you would receive from that bonus if you satisfied all the playthrough requirements.

UK Casino Player Support Tests

  • Email Support Test
    We emailed every UK online casino with 10 questions and measured whether they responded and how long it took them to answer.
  • Live Chat Support Test
    We collected any information about live chat and its operating hours from the UK casino support pages.

UK Online Casino Player Experience Tests

  • Casino Game Library and Slots Selection Test
    We counted the number of casino games available from each UK online casino as well as the game types in each casino’s portfolio.
  • Website Speed Test
    We tested the load times across several important casino pages and averaged all the results to calculate how quickly each casino is.

Based on the result in each test, every casino was rewarded 1-5 stars. Jump to full test score card.

When all tests where done, we calculated an average and total score for every online casino in the United Kingdom, to then build an unbiased ranking system. This combination of stars and ranking helps us provide you with an objective view of the best UK online casinos.

UK Online Casino Bonus and Promotions Tests

We tested the no deposit bonuses and the first deposit bonuses for all licensed UK online casinos.

UK online casino bonuses and promotions are typically some of the most important factors for players when deciding which online casino to choose. With this in mind, we set out to find the best UK online casino for casino bonuses and promos. What promotions does each UK casino offer to new players? Does that casino have a no deposit bonus? What is the “actual” value of this casino bonus?

Not only are these important questions, but the answers to these questions can greatly influence the success and enjoyment you experience while gambling online. If you choose a UK online casino with a poor bonus, you are less likely to win and may risk more money than you need. Instead, try gambling at a UK online casino with more free spins, better no deposit bonuses, and more generous welcome bonuses to new players.

First Deposit Bonus Test:

  • To find the best first deposit bonus in the UK, we used a metric we created called the Actual Bonus Value (ABV). The ABV is a formula that calculates the most likely value of a bonus based on wagering requirements and other considerations from the terms and conditions of that bonus. The higher the ABV, the better the bonus.
  • One of the best online casino in the UK according to our first deposit bonus test is PokerStars Casino with an ABV of £20.95 for a £100 first deposit. Our estimates suggest that players could net £20+ from the casino bonus alone if they join and play the highest available RTP slot game.
  • 29 of the UK online casinos we tested actually had negative ABVs for their first deposit bonuses — meaning that you would most likely have to use your own money from the £100 first deposit to satisfy the wagering requirements, thus leading to a negative return in many cases.

No Deposit Bonus Test:

  • To measure UK casinos’ no deposit bonuses we used the same ABV formula above, but based the input values on the casino’s no deposit bonus — if it had one.
  • Unfortunately, as of our most recent test — no UK online casino offered new players with a no deposit bonus. They only had first deposit bonuses available.

UK Online Casino Support Test

We researched phone, live chat, and tested email support at online casinos in the United Kingdom.

Casino support may not seem like a huge consideration when deciding on which UK online casino to sign-up and gamble at, but if you have issues with withdrawals or need help understanding wagering requirements of bonuses, you may think differently. The last thing you want to do is sit on hold all day waiting for phone support or be ghosted by the email support team at an online casino when you have a question. So, we decided to research and test each UK online casino to see which one had the best or worst customer care team.

Email Customer Support Test:

  • To measure how good a casino’s email support team was, we sent 10 different questions at various days and times from separate accounts and measured if and when we received a response. For our test, we removed auto responders and focused on manual responses — even if they didn’t answer the question technically. The faster the manual response, the better the score. The average response time and overall reply rate influenced our rankings for UK online casinos.
  • One of the best online casino in the UK for email support was Rainbow Riches Casino which responded to 100% of our emails and averaged a response time around 61 minutes (1 hour).
  • Some of the worst UK online casinos for email support included Betway Casino, VoodooDreams Casino, NYspins Casino which all failed to respond to every email and averaged more than 24 hours between email responses.
  • Here you can read the full casino email support test, and here you can find our top list of the best casino customer support UK.

Casino Phone Support:

  • We intend to but have not yet had the opportunity to test phone support from UK online casinos. However, we have collected and shared the phone numbers of each UK online casino in case you prefer to reach out to the casino support via phone.

Live Chat Support:

  • We intend to but have not yet tested the live chat support from each UK online casino. We have researched and shared the displayed operating hours for live chat support from each UK online casino if that was displayed on their customer support page.

UK Online Casino Website and Game Tests

We tested game libraries and website speed for all UK online casinos.

The casino game library is an important and often understated consideration when looking for the best UK online casino. After all, would you rather play at an online casino with more or less games? What about a casino that has several different types of games vs one with only slots? Not only is the game library a critical part of the gambling experience, but the literal technical gameplay can influence how much fun you have while gambling at that online UK casino.

These two factors were the foundation for our gambling experience tests which looked at how large and diverse a casino’s library was in addition to how quickly that virtual casino loaded on average. These tests give us numerical and quantifiable metrics on which to measure and rank UK online casinos in the categories of user experience.

Casino Game Selection Test:

  • To measure the number of casino games in each UK online casino’s library, we simply counted them. While online casinos in the UK do update their game catalog regularly and our number may not reflect the realtime size of the casino’s library, it is accurate as of our most recent test and consistent with when all other UK online casinos were tested.
  • The top UK online casino for game library size was Videoslots Casino with 6,237 total casino games available.
  • To measure game variety, we looked at how many different types of casino games (outside obvious games like slots, roulette, and blackjack) that a casino offered in the following categories: Live Dealer, Sportsbook, Live Betting, Daily Fantasy Sports, Poker, Bingo, Horses. The more game types a UK online casino had in its library, the higher the rating in our test.
  • The best UK online casinos for game variety included Unibet Casino, NetBet Casino, Xtremewin Casino, Betiton Casino, Tebwin Casino, Luckster Casino, Hopa Casino, Mr. Mega Casino, Luckland Casino, Mr. Play Casino, ZetBet Casino, 10Bet Casino, BZeebet Casino, Betway Casino, Coral Casino, Ladbrokes Casino,  and Parimatch Casino which all offered all 7 types of betting options.
  • You can read the full casino games and slots selection test here and view our toplist of the best UK online casinos for game selection.

Casino Website Speed Test:

  • To test the gaming experience of an online UK casino, we felt measuring the page speed was a great opportunity to apply quantitative value to that category. After all, slow loading online casinos can signal more critical issues than just the playing experience — it can be a red flag for further technical issues and oversights from that online casino. So, we collected 10 important pages from every UK online casino including pages like
    • Homepage
    • Casino Bonus/Promotions Page
    • Slots Page
    • Customer Support Page
  • We then tested each casino more than 300 times over several days and days of the week to collect a large sample of load times from each UK online casino. These times were then averaged to find the average speed of each online casino in the United Kingdom. The average score is what we used to rank and score each casino.
  • The average load time across all UK online casinos was 2.95 seconds which is surprisingly high.
  • The best online casino in the UK according to our page load speed test was Vegas Mobile Casino which loaded in 0.33 seconds with Spinzwin Casino a close second at 0.36 seconds.
  • The worst UK online casino in our speed test was Griffon Casino which averaged 14.7 seconds to load — which could significantly affect your gaming experience.
  • Here you can read the full casino website speed test, and here you can find our toplist of the fastest loading online casinos in the UK.

UK Online Casino Tests: Pros, Cons, and FAQs

Creating and executing tests of 130+ UK online casinos presents many challenges — here are some of them.

Our tests of online casinos in the United Kingdom are static and based on the date they were last tested. While not 100% accurate, we believe our tests provide a good vantage into how each UK online casino performs across our categories of bonuses, game selection, gaming experience, and customer support.

While we are working to automate our tests as much as possible which will allow for more real-time updating and more accurate data, we are currently limited to hybrid/semi-automated testing which means the results are up-to-date for when we last tested the UK casino market.

Our goal is to provide objective and quantifiable ratings for each UK online casino, and we have yet to find a scalable solution for measuring UX beyond website speed. We do believe that an online casino’s appearance and responsiveness (i.e. mobile app) are important considerations for players, but have not been able to find an efficient way to test and measure these other, more subjective factors.

We are working on finding a better way to measure the quality of responses we received in our customer support tests. While measuring an answer as good or bad is a bit subjective, we do believe there is a way to track helpfulness and politeness of casino support — which we hope to include in future review releases.

Deposits and withdrawal times really important for the online casino experience, and we are committed to finding a scalable way to test the withdraw and deposit speeds of UK online casinos.

Unfortunately, we have not yet found a way to do that efficiently. It’s part of our roadmap and hopefully will be in future reviews.

We also believe the mobile casino experience is another important category that we have not yet had a chance to test effectively. We do intend on finding creative testing strategies to measure the mobile gambling experience at UK online casinos in the future.

VIP programs and other player retention strategies from UK online casinos have not been considered in our current testing process. We are looking for ways to gain reliable and relevant data on VIP programs, but until we are able to collect that information — VIP programs will not be included.

Summary of UK Online Casino Test Results

Overall, the UK online casino market is filled with a variety of gambling options with more than 200 licensed casinos active to the public. In fact, the UK Gambling Commission has issued almost 4,000 licenses across 3,000 different gambling companies. With so much competition for players, you might expect casinos to compete for players with great first deposit bonuses, free spins, and no deposit promotions — but, to our surprise, UK online casinos had some of the lowest valued offers to players compared to other markets.

The average welcome bonus offer to UK online casino players was -£2.32 which means that most UK online casinos will require players to use their own money to satisfy the wagering requirements of their welcome bonus offer. This includes no deposit bonuses, first deposit bonuses, and free spins. Our research also found that no UK online casinos had no deposit bonuses for new players. This means, every welcome bonus offer will require you to register and deposit money into your account.

While bonuses and promotions were a big part of our study, we also test other areas like game variety and depth. When considering how to find the best UK online casino, we felt like the game library was an important factor to test. The size of the casino library was a big part of that test, and we discovered that the average UK online casino had 1,557 total games in its library — although some had much more like Videoslots Casino (6,237 games), QueenVegas Casino (4,578 games), PlayOJO Casino (4,521 games), Casumo Casino (3,140 games), and SlotsMillion Casino (2,916 games).

Our other tests looked at areas like casino player support and website speed which are both influential to the gambling experience at an online casino in the United Kingdom. Customer support was overall pretty good across the board with UK online casino support responding to 75% of our emails. The average response time was less consistent with several outlier taking multiple days to respond.

For casino page load speeds, the average for UK online casinos was 2.95 seconds which is quite high compared to where we expected it to be. The overall average load time across the entire internet is estimated at around 2.5 seconds, so the UK online casino market is slower than the average website. This score was driven down by a few outliers with casinos loading in 10+ seconds like Griffon Casino (14.7 seconds), Foxy Bingo Casino (13.5 seconds), BoyleSports Casino (13.3 seconds), and SlotsnPlay Casino (10 seconds).

Our goal at Great.com is to provide visitors with the resourced needed to make an educated decision about which UK online casino to play at. By making a more informed decision, you can decrease the risk of losing and increase your odds of enjoying your time. Gambling is meant to be fun, and we hope that the information you find here helps you have more fun — whichever UK online casino you choose!

If you don’t make an informed decision, you might end up playing somewhere with very limited options, no promotions, and a customer support that doesn’t bother to answer.

UK Online Casino FAQs

These are common questions about playing at a UK online casino.

Yes, you can gamble online in the UK. The United Kingdom has a well-regulated and established online gambling industry, which has been possible since the introduction of the Gambling Act in 2005. This piece of legislation created a legal framework for various forms of gambling, including online casinos, sports betting, poker, and bingo. The Act aimed to prevent gambling from being a source of crime or disorder and to ensure that gambling is conducted fairly and openly.

The Gambling Commission, an independent regulatory body established under the Act, is responsible for licensing and regulating online gambling operators in the UK. These operators must adhere to strict rules and guidelines to maintain their licenses and provide a safe and secure environment for players.

As long as you are at least 18 years old and are playing on a licensed gambling site, you can legally participate in online gambling in the UK. It is important to gamble responsibly and to be aware of the various tools and resources available to help manage your gambling behaviour, such as setting deposit limits and taking self-exclusion breaks if necessary.

It’s difficult to find an exact number of online casinos at any given time because new casinos open and old ones close frequently. As of our most recent test, there were more than 130+ UK online casinos.

InterCasino is often credited as one of the pioneers in the online gambling industry, having launched in 1996. While it wasn’t exclusively a UK-based casino, it did accept players from the UK, and it played a significant role in shaping the online casino landscape in the early days of the industry.

Kitty Bingo Casino tested the highest in our first deposit bonus analysis with a bonus value of £23.02 on a £100.00 first deposit.

UK Online Casino Reviews Explained

Our UK casino reviews are fully based on the different tests that we have done. We want to be as objective as we can in our tests and not focus on anything that can’t be measured. As you can see in our overview of all casino tests, every casino has received a star rating based on how they have performed. These tests and stars are the foundation of our casino reviews. In our toplist of all UK online casinos, you can find links to all casino reviews on the site.

Overall Casino Score and Contact Details

Our reviews start with the overall ranking of where the casino is placed compared to all other casino gambling sites in the country. This is then followed by contact details and support opening hours to make it easy for you to reach out if you need help.

Images of Casino

The next section includes a few images from the casino. Including the homepage, the online gambling lobby, and an image of a popular slot game they offer.

Ratings Overview from Casino Tests

The third section of our UK casino reviews is a quick overview of the different tests that we have done.

In this section, we have combined the no deposit bonus test and the first deposit bonus tests into one star rating. We have valued the no deposit bonus to 20% of the total promotions score and the deposit bonus to 80% of the total score. We have done this since the deposit bonuses are more common and that they play a more important role in your chances to win than the deposit bonus does. For example, if a casino has 3 stars in our no deposit test, that will account for 3 * 0.2 = 0.6 stars in the full score, and 4 stars in our deposit test, it will account for 4 * 0.8 = 3.2 stars. Total score in the promotions overview will be 0.6 + 3.2 = 3.8 stars.

We have also conducted email support tests. Here, you will see the average response time and reply rate of each casino and how well that compares with all other UK online casinos.

For software and games, it’s currently only based on the number of games and game types that the casino offers. Website speed stars are only based on our page load speed test.

Actual Bonus Value Section

After this follows a section about the Actual Bonus Value (ABV). We have chosen to give this box a prominent position because we believe that ABV is a much more important number than what kind of casino bonus is being offered. The higher the ABV, the better the bonuses.

Top Casinos Comparison Tool

When continuing to scroll, you’ll see our gambling sites comparison tool. Here, the casino that is being reviewed is easily compared to other casinos in the United Kingdom. By sliding sideways, you can easily see where the casino excels and where it performs poorly.

Casino Bonus Section

If you want to increase your chances of winning in a UK online casino. This section of our casino reviews is the most important. First, we break down each bonus being offered to show how well it holds up against other offers in the country. Secondly, we show you the best way to play a certain casino bonus to get the most value out of it. What casino games should you play? Should you play slots or other games? How should you bet? We have done all the calculations and explain it to you in detail.

Following Sections

The last few sections of our casino reviews are more self-explanatory and tie back to the casino tests you’ve read on this page. They focus on the customer support quality, the website speed, and the casino games selection. This can be read in detail if you want to dig deep into something or just be looked briefly at in the overview section. We recommend using the overview to make sure you avoid the casinos with terrible customer support and with very limited games, but we wouldn’t base our decision on what gambling site to play at based on if a casino placed 5th or 6th in the number of slots games, or if they were 7th or 10th in customer support. As long as they performed better than average on these numbers, you are good to go!
