Choosing the Best UK Online Casinos
When choosing the best UK online casinos, players should think long and hard about what it means to be the best.
In the world of online casinos, it usually has something to do with a casino’s strength as an all-around product. Are the games of the highest quality? Does the site look well designed? Is it safe and secure? How do the payment options compare?
All of these questions should be asked before you choose which UK casino site to sign up to. Our meta-score reviews take into account all these aspects when determining the overall casino score and serve as an at-a-glance reference for choosing the best casinos.
What are Online Casinos?
The UK casino sites which have snapped into prominence off the back of the rise of the digital age are fully aware of the profits to be made from online casino gaming. The most profitable online casinos are the ones that have taken the casino model from land-based casinos and successfully translated this into an online experience with a similar level of excitement, variety and the potential for big wins.
These days, more and more players have the choice to go to an online casino site based on their own criteria of what makes an online casino special. Here, they can wager real money against real players and hopefully make a profit. This has been quite the game-changer for the gambling industry. The range and variety of choices available and the results they yield will vary wildly. Nonetheless, there is an abundance of players looking to win serious money online now. Online casinos provide a valuable niche for both seasoned gamblers, casual players and casino newbies to test their skills and luck from the comfort of their own homes, or increasingly, from their mobile phones.
Games & Software Developers
An over-the-top layout and generous sign-up bonuses do not guarantee that an online casino site is going to be top quality. A range of casino games is important, so you should be looking for a UK casino site with a choice of slots, video poker, live dealer and table games, though what to look for will mostly depend on you as a person and how much experience you have. As you gain experience playing online will soon become aware of the various software developers who provide the actual games that make online casinos tick-over. Each developer has their own style and reputation and each player has their favourites.
Look for the games you want to play most. Slots? Blackjack? Poker? A good UK online casino will have all of the classics and then some. If you are at all worried about being thrown in at the deep end, it is advisable to start out on a demo account when possible, until you get to grips with it, and it may also be wise to start out with a game that you already have some on or offline experience with, giving you more confidence when you play.
Always do your research when signing up for a new online casino. They should be everything they say they are.
It is up to you to decide if you want to play there, remember, not them. If a site is worth a punt, its reputation will usually speak for itself, but players have more confidence in a known and trusted brand that’s been built up over time. Some date back many decades have changed with the times to meet the ever-growing demands of the online casino market.
The more experienced players tend to do a few thorough comparisons to see which one suits them the most before making a deposit, but keep in mind that no casino is immune to negative feedback, and remember that not all reviews you read will be genuine. Make sure you can find details regarding any licenses and that they are regulated by trusted authorities. As a rule of thumb most respectable review sites will let you know if the casino is properly regulated and licenced.
Best UK Online Casino for Bonuses
With how competitive the online gambling industry is, it is no wonder companies are always dreaming up bigger and better ways to lure in potential new players, as well as keeping the existing ones happy.
With so many new casino sites jumping on the bandwagon, it is sensible to do some digging and comparisons to find out where’s offering what and how this can benefit you the player.
There are a number of different types of UK online casino bonuses to choose from to help you decide which ones are worth your precious time and hard-earned money. Far too many players out there don’t understand the value of these bonuses, often becoming disillusioned with online casinos on the whole, but it doesn’t have to be this way.
Whether the casino offers bonus free spins or free plays, the number one thing to remember is that it needs to be converted into real money before it has any real value.
Wagering requirements must first be met in order to cash out your bonus, so be sure to have a good read of the casino’s terms and conditions before you make a deposit.
There are a few factors to consider when adding up the casino bonus such as the wagering requirements and the percentage a game provides towards meeting them. This basically means the number of times the bonus must be wagered before it can be withdrawn.
Although such requirements will vary from site to site, the majority can range between 25x and 35x the bonus plus deposit. A wagering percentage dictates how much each game contributes to the wagering requirements, with table games like roulette generally offering a lower percentage than slots. Confused? Don’t be, it’s very simple once you get into it.
A house edge is what the casino expects to keep over extended periods, meaning if a site has said a 10% house edge, they are gaining a 10% profit over time. A lower house edge means more favourable odds for the player and the house edge on a specific game will generally dictate how much you need to put in before you draw a profit. The house edge is important because the casino needs to make sure it is big enough to stop players from abusing the bonus, this is why they specify that you can only play certain games when meeting the wagering requirement.
Remember, results may vary. Just because a casino site claims 100% match bonuses, the wagering requirements need to be investigated. Deposit bonuses aim to encourage casino sign-ups with terms and conditions attached. So look for differences in the requirements and consider your options carefully.
Ultimately, whether or not you should take a bonus will largely depend on what games you are playing, the wagering requirements, and the edge of the house. If you are hoping to decrease your risk of losing money, such bonuses can be of great benefit as you can increase your overall chances of winning big.
Don’t rush into anything, shop around for the casinos that offer the best value and odds. This will definitely prevent you from making any mistakes that you might regret further down the line.

The Top UK Online Casino for Software
When choosing new online casinos, one of the key factors that should be considered is the casino software providers used, and for a number of good reasons. With so many casino software developers duking it out for supremacy, it only makes sense that you as their customer only choose the best. You really want to make sure that the casino sites you are considering signing up with uses tried and tested brands that have built up a strong reputation over a long period of time, and are known for the functionality and reliability of their products. You are far more likely to avoid disappointment down the road by doing so.
The relationship between the UK online casinos that are doing the best and the software providers that they use is not to be overlooked. This is because the casinos that are doing the best are bringing in more paying customers, and, as such, have more money to invest in their games and software. Ideally, you want to be putting your money down on sites that are powered by well-known software developers such as Microgaming, NetEnt, Playtech, IGT and Play n Go, to name a few of the big hitters.
You as the player can play with more confidence when you know you are in good hands. These companies invest a lot of time and money into bringing you the cream of the crop in online games. They understand the importance of a solid reputation and thus will go to great lengths to uphold their standards.
Since the license fees for the best games almost always are at the top end of the spectrum, the smaller online casinos are simply unable to compete with the bigger casinos, and as a result, they tend to opt for working with smaller, less-known software providers. This in turn, however, has created a new market that has given independent software developers a launching pad, though players should still approach unknown software developers with caution.
Aside from creating enjoyable games, software providers manage other parts of the online casinos in order to create a more user-friendly experience, such as live dealer poker games. With so much competition out there in the world of online casinos, it’s no wonder that a lot of the high-end software companies are careful when they select which casinos they are going to work with.
Unfortunately, there are many fake or untrustworthy online casinos out there, alongside many phoney (or just plain bad) software developers who have no real interest in providing you with an enjoyable experience and instead only care about you making an ill-informed deposit to their sites.
With this in mind, it is a wise tactic to play it safe and stick with the more known developers. Yes, the gambling sites they operate on may require bigger deposits or more stringent customer checks but at least you will know your money is safe.
When it comes to software providers, bigger is most certainly better.

Making an Online Casino Deposit
So, you’ve found an online casino you like, you’ve tested out the games on a demo account, and now you’re thinking of making a deposit with your cold hard cash. Go you! However, before you lay a single penny down, there are a number of things for you to be aware of.
Unfortunately, there are far too many dubious online casinos out there for you to be taking any unnecessary risks with your money and your data. The best UK casinos tend to be more reliable when it comes to security as they have trustworthy reputations to uphold, and as such will use better firewall software and encryption. This keeps hackers a bay and ensures that your data is safe and secure when you make a deposit. Having tight security helps online casinos to stand out from their competitors, it is good to check whether the site is licensed and registered.
When it comes to actually make your deposit, the top UK online casinos will offer a number of different ways to make a deposit. Double-check that you are happy with the payment methods they use beforehand. Debit and credit cards are widely used, with PayPal also being a popular choice. Some sites also accept digital wallets and vouchers, though these tend to be less used.
Most casinos will want to see some form of identification before they process any of your payments. This usually entails you sending them a scanned copy of your passport or driving licence. Once done, there will sometimes be a slight delay while your account is being verified, so don’t panic if a deposit doesn’t go through right away, and don’t be afraid to contact customer support if you have any concerns or queries.
If you have any doubts, a quick Google search on the site you are looking at will tell you if other people have had issues that should be a cause for concern.
UK Online Casinos Q&A
Here are the most common questions and answers associated with UK online casino sites.
Are the top 20 UK online casinos you promote really the best?
We think so, yes. However, these are reviews and some things are matters of opinion. Our chief reviewer likes the colour red, coffee, and blackjack. If you like the colour blue, tea, and roulette that’s fine. We are confident that our reviews are honest and thorough. Take them as a starting point and go and check out the sites we recommend. We do our best to make sure we give you good, honest advice and that we have up-to-date information. We will never recommend an unsafe, dishonest casino site or one that doesn’t offer a quality experience. As to the best – that’s a decision for you to make.
What is the best UK online casino in 2021?
The best UK online casino in 2021 will have up-to-date licensing and serious auditing, with great policies on player safety, data protection, and account security. Plus a good help service. The best UK online casino in 2021 will have hundreds of good quality slots from a variety of providers. The best UK online casino in 2021 will offer more than that with a range of table games and ideally a top-notch live casino. The best online casinos for UK players will be available to mobile players either as an app or via a great quality mobile website. This is where we start when we look at the best online casinos for UK players.
What makes a top UK online casino?
This is a decision for you because one player’s beautiful design is another player’s acid-toned nightmare. We’ve covered some ground in our previous answer – security and trust, good games, and mobile accessibility – that are the basics. You’ll also want to see a generous welcome offer, plus a programme of ongoing promotions that shows that the site cares about keeping you interested for the long run. A good experience is a thing that most players want from any website that they’re going to have a long-term relationship with, and choosing your top UK online casino will take a bit of time, and probably signing up with and checking out more than one UK online casino site.
Do online casinos pay real money?
Sadly, there’s no way to download crisp £20 notes to your modem or phone. Yet. However, online casino pay out real money. It might come in the form of a bank transfer, a cheque, money into your debit or credit card account, or into an online wallet, but you can absolutely take that money and spend it on whatever your heart desires. They also cost real money, so you need to have your wits about you when you play, but with a bit of skill and a lot of luck you might well find yourself taking out more than you put in. Financial safety is a big responsibility for players and it’s something we take very seriously too. We urge you to follow our advice and check out safe gambling practices as well as prize funds.
Instant vs Download Casinos – what to choose?
In 2021, UK online casinos should offer you a good experience whether you choose to download something to play on a desktop computer or an app on your phone home screen. There are pluses and minuses to each experience. Download casinos for desktops are less popular, but apps are a much more accepted part of the mobile world – if you like a site, why not make it easy to get to it, and to cash in any potential exclusive app-only material. But don’t let an app tie you down. Sometimes you need to shop around, and one of the reasons why casino sites are so keen that you should download their app is because they know you’re more likely to stick with them.
Do online casinos cheat? How can I know a UK online casino is safe and the games are not rigged?
You really can win money at online casinos, yes. However, the reality for many players is that they will lose relatively small sums of money in the long run. You need to be realistic and honest with yourself about online casinos if you’re going to have a safe and enjoyable time. Some people will win life-changing sums of money. Most will not. You’ll almost certainly win from time to time, and you’ll be up on the deal for part of your time at a casino site, but an online casino is a successful business and your money is their profit. The best and safest way to think about your casino entertainment is as entertainment rather than as a source of money.
How to avoid online casino scams?
We will do our best to keep you safe. We’ve already told you the baseline for safety – licensing, auditing, good safety policies, support for safe gambling practices. The reality is that full-on scams are relatively few and far between these days, and the sad fact is that most of them rely on players not behaving well. Read a bit of history on con games and you’ll see nothing changes and that most con games are based around the “mark” fooling him or herself. Don’t chase money. Don’t play when you’re desperate for money. Don’t play when you’re vulnerable. Or intoxicated. And follow our safe gambling guides.
Why will reading casino guides and casino reviews will make me a better player?
It might not. No advice is of any use if it’s not followed. It’s also true that luck is by far and away, the defining factor on how you’ll do in a UK online casino. That’s a fact, and any site that tells you any different is doing you a disservice. We think that’s why we’re different and that’s one way in which we give you better, safer advice than other sites. A site that tries to sell you game-winning systems is trying to scam you – stay away. Play safe, learn the rules, read the small print, check the licence… it’s honest advice like that that will make you a better player, not false promises about betting systems that can at best slow down your rate of loss.
What are the best casino games to play online?
What’s your fancy? Slots will give you the most choice. Table games have heritage, history, and a touch of sophistication. Live casino games are an unrivalled experience with a bit of a social side to them. Check out tables – ideally, at the casino site you’re playing at – and you’ll find a list of theoretical return to players, which will give you some idea of which games you can play with the most chance of playing to win. But the truth is, the best casino game to play online is the one you enjoy the most: if that’s good old-fashioned one-on-one blackjack with a live dealer, play and enjoy that; if it’s the latest six-reel slots in 3-d then play that. There’s never been more choice. Enjoy it!
New vs Established Casinos, what to choose?
All the UK online casino sites you’ll find here are safe. And almost all sites offer enough in bonus funds or free spins that you check them out essentially for free and without risk to your own funds. That gives you a lot of freedom. Established sites have proved their worth in a tough business. If a site is more than five years old, it’s probably fair to say that it’s doing something right. But if you’re a real welcome bonus and promotion hound then there’s no better time to scout for these than when a site first opens its doors. There are pros and cons to either, and the best decision is to shop around and have high standards.
What are the best payment methods to make an online casino deposit?
Security and safety are your first priorities with any online casino site. They’re ours too. All the sites we review or recommend can be used safely. So can all the payment methods they accept. None more so than PayPal. PayPal’s interesting history with the casino industry – they ducked out of it for several years while the law in the US was in doubt – means that the world’s favourite online payment method is still a relatively rare badge of good quality on sites. It’s also rightly highly trusted and has the power to give its customers good deals. But nothing is more convenient than Pay by Phone. UK online casinos in 2020 are overwhelmingly mobile businesses, and a mobile-first payment method is better by design. It’s set up for mobile customers and for mobile tech, so it’s both super safe and completely convenient.
