Best 2021 Casino Sites | Top UK Casinos

Play at the top-rated casino sites in the UK

Looking for the best casino sites? Our guide lists the UK's top sites & explains what's so great about them, from slots & poker to bonuses & payouts.

Best casino sites UK

The UK’s leading casino sites are among most respected on the planet. 

They’re held to high standards by both the UK Gambling Commission and the people that use them, with players demanding a great experience and a variety of games. 

The top online casinos should be just as simple to play on your phone as they are online via a desktop, with both devices making it easy to find the casino games and sports you want to bet on. 

One of the key things that separate the best from the rest in the online gambling industry is the level of customer service you get from the site. 

You should be able to get quick and accurate responses to any query you make, so you only have to spend the minimum amount of time away from your favourite games.

All you need to do is read our reviews and decide which ones offer the things that you want from a top casino.

How we review the leading casino sites

Reviewing UK online casino sites is something we take great care and pride in. 

Just like you, we’re players who love testing ourselves on the best casino games and we expect the very best from the websites that we choose to invest our time and money in. 

There are some key things that we look for when we’re reviewing casinos for you: 

Games

Games are the single most important part of any great gambling site. We look at the quality and quantity of the titles on offer, along with the software providers they’re made by to ensure you get the best games at your favourite sites. 

Security 

Security is a top priority for us when we review a casino. We need to know you’ll be safe when you place your bets and that’s why we make sure the site is recognised by the UK Gambling Commission. 

Payouts 

Payouts tell you how likely you are to win at a given gambling site and casino game — and it’s not a lot of fun if you keep losing! This is why we highlight what payout rate you can expect from the leading casinos we review. 

Bonuses 

Almost every online casino will offer at least one bonus code to its gamblers (some new casino sites have multiple rewards). But that’s not all we consider in our reviews. We look at all aspects of a site’s bonuses, including whether it has cash only bonus funds or if you can only use the free bonus spins on selected games. 

We take all these things into consideration and more when we’re deciding which websites we believe meet the high standards you expect when you’re gambling. 

But most importantly, we also ask ourselves if we’ve had a good time and feel safe when using these gambling sites. 

We’ve tried each and every one of the UK online casinos and we can confirm that they not only meet the standards you expect, but they also excel at them. 

Introducing OnlineCasino.co.uk’s team of gambling experts 

OnlineCasino.co.uk’s expert team is made up of casino gaming players, sports betting fans and gambling industry specialists. We’re passionate about playing the best online casino games, betting on the top sports, keeping up to date with the latest industry news and making sure you have the best possible experience at your favourite casinos in the UK. 

Our experience enables us to review online casinos like players — because that’s what we are, players with expert knowledge of casino games and sports betting. This means you can trust when our team says a site is great for live dealer games or doesn’t have the most competitive bonuses because they’re speaking about their real-life playing experience. 


The team at OnlineCasino.co.uk are really proud of their work. We take pride in writing the most detailed and accurate casino reviews, games tips and industry guides, which are fully transparent and abide by all gambling compliance rules. But the thing that makes us most proud is knowing that we’ve helped you to find the right gambling sites, with the games you want to play. 

Licensing and legislation to look out for at casino sites

The number of available betting options, range of games, bonus options, and level of payouts on offer aren’t the only things you need to look for in the top casino sites. 

You also need to be certain that you’re betting at a safe casino site and that means comparing the licensing and legislation. 

Having spent a lot of time looking at the most highly regarded casino sites, one thing is clear to us – you’re better off knowing the right licensing and legislation authorities to look out for than trying to compare casino sites directly. 

For this reason, the top casino sites have all of the licensing and legislation authorities listed in their websites as a matter of course – if they didn’t they’d put themselves at a massive disadvantage. 

With this in mind, these are the licensing and legislation authorities you need to look out for. 

UK Gambling Commission

Any casino site that operates in the UK will be regulated by the UK gambling commission. 

Government of Gibraltar 

Look for the Government of Gibraltar logo on casino sites.

If a casino site is licensed in Gibraltar then you’ll find the logo of the Gibraltar government on its site. 

Malta Gaming Authority 

Look for the Malta Gaming Authority logo on casino sites.

If a casino site is licensed in Malta then you’ll find the logo of the Malta Gaming Authority on its site. 

Spelinspektionen

Look for the Spelinspektionen logo on casino sites.

If a casino site is licensed (or is able to operate) in Sweden then you’ll find the logo of Spelinspektionen (the Swedish Gambling Authority) on its site. 

It’s not only the authorities that regulate casino sites you need to look for. 

You also need to know that you’re using a casino site you can truly trust. It is therefore recommended that you check to see whether they have the logos of organisations that support responsible gambling

GameCare

Look for the GamCare logo on casino sites.

GamCare is a UK-registered charity that helps people who believe they may be a problem gambler. 

GAMSTOP

Look for the GAMSTOP logo on casino sites.

Credit: GAMSTOP

GAMSTOP is an organisation that allows you to self-exclude from casino sites. The idea of this is that you register your intent to self-exclude from a casino site for a set amount of time and during that period you’ll be blocked from gambling there. 

How does the Gambling Commission protect UK players? 

The UK Gambling Commission regulates all online casinos (established sites and new online casinos) that operate in the UK. That includes those with headquarters in the UK and those based in other countries around the world. 

The Gambling Commission exists to protect UK players and it does so in the following key areas that are backed up by stringent regulations: 

  • Fairness of casino games 

  • Protection of players’ data 

  • Responsible gambling 

  • Crime prevention 

  • Customer complaints 

  • License enforcement 


Below, we explain how the Gambling Commission protects UK players in these areas. 

Fairness of casino games 

The Gambling Commission approves casino games manufacturers to ensure all of their titles are fair. Online casinos are only allowed to offer games from approved manufacturers, so you can be certain that any casino games available to UK players (like yourself) are fair. 

Online casinos are also obliged to hold sufficient cash reserves to ensure they’re able to pay out all player winnings in full. This means you can be sure that if you win an online casino game then you’ll get the money you’re entitled to. 

Protection of players’ data 

The UK has stringent laws on data protection, including for people using online casinos. All gambling sites must pass tests to demonstrate that they look after their players' data, protect funds and any records of communications from external access, and have secure and verifiable methods of payment. 

Responsible gambling 

All UK casinos are obliged to have strict checks and procedures to ensure people gamble responsibly and that minors don’t use their facilities. 

Casinos look after problem gamblers by including a variety of resources on their sites that allow anyone (including friends and relatives of players experiencing gambling issues) to seek confidential help. Casinos must also provide players with options for self-exclusion and deposit limits, so they can control their access to games and sports betting options. 

Gambling sites protect minors by having comprehensive ID submission requirements when setting up accounts. Players must provide approved forms of photo and address identification, so the sites can validate who they are and confirm they’re old enough to use their facilities. 

Crime prevention 

Alongside measures to ensure minors don’t gamble on their sites, online casinos are required to have procedures in place to prevent money laundering. As the industry’s regulatory body, the UK Gambling Commission has the power to take action against casinos if it believes they aren’t doing enough to prevent criminal activities. 

Customer complaints

All UK casinos are obliged by law to give their players access to an independent body that will review any complaints they make against gambling sites. This independent body is known as an alternative dispute resolution (ADR) service and it provides impartial support to players. 

License enforcement 

All online casinos that operate in the UK are subject to the rules and regulations of the Gambling Commission. If the Gambling Commission believes that its rules and regulations have been broken then it will take action to protect its players. These actions include sanctions, fines and the suspension (even revoking) of their gambling license. 

Why free spins matter when reviewing the top casino sites

Casino sites have many more than three slots games that you can play but make sure you keep your personal money separate from cash funds for gambling

Credit: Flickr

Free spins are a big money spinner for casino sites – pun, of course, intended. 

Free spins can start gamblers off with credit in the bank, which they can use on slot machines. This means they don’t have to spend their own money to place a bet. 

While the number of free spins you get from the finest casino sites is certainly appealing, you need to look a little deeper than this to see if you’re really getting a good offer. 

The things you need to look out for include: if you have to use your spins on selected games; if there’s an expiry date on them; and if you get them all at once (some are teased out over a few days). 

Free spins are certainly an important factor in comparing the best online casino sites, but they’re certainly not the only ones we care about – if anything, they are what they are: a nice little bonus and nothing more. 

How do I know what the payouts are at casino sites?

Three blue, three red, and three green casino dice rest on a wooden surface

You can find out the payouts available at the best UK online casinos by looking for their RTP. 

RTP is the amount of money that’s paid back to gamblers, over time, when they bet at casino sites and wager on specific games. 

The way it works is like this: If a casino site has an RTP of 97% then it means that for every £100 spent, £97 is paid back to gamblers over time. This means that the site has a ‘house edge’ of 3% over its gamblers.

Now, before you get excited, RTP doesn’t mean that for every £100 you spend you’ll get £97 back. The reason for this is that it takes into account every gambler and every bet placed, and some people win big or lose big. 

Each casino site has an overall RTP and each individual game has its own RTP (we cover the main games in the rest of this guide). 

We recommend that you compare the RTP of the casino site you select and the game you play against rival options before you spend any money. 

How do I pick a great casino site to bet at?

There’s so much for you to think about when selecting the casino site you’re going to place your bets at. There’s the games it offers, the bonuses it advertises, the payouts it offers, and lots more. 

We understand this and it’s why we spend huge amounts of time playing the games, reading the T&Cs of the bonuses, and finding out the payouts at the top websites. 

We have a robust reviews process that we’re proud of and reading our assessments of the best sites is a great way to pick a great one.

However, the most important thing is that you must know what you’re looking for.  

Do you care most about bonuses, games, payouts, or something else? 

Once you know the things that matter to you then you can read our reviews, find the sections you care about and decide which casinos meet your requirements. 

We give you all the tools to pick a great casino, you just have to use them. 

What are the key bonuses to look for at casino sites?

Bonuses are one of the key parts of the best UK casino sites. 

They give you the chance to earn some extra cash or casino credit to use when playing your favourite games, potentially allowing you to win some money. 

These are the main casino bonuses you should look for: 

  • Welcome bonuses 

  • Free spins 

  • No deposit bonuses 

But you shouldn’t only keep an eye out for these rewards.

The very best casino sites offer ongoing and ad hoc promotions to their returning players. This means you should also check the VIP offering when you visit a gambling site. 

Do online casinos allow card counting?

Card counting is a blackjack tactic that is designed to help you make the right moves at the right times, increasing your chances of making winning bets. 

While this isn’t outlawed by casino sites, it’s almost impossible to count cards when you’re playing online games of video blackjack. 

However, it may be possible to count cards when you're playing live dealer blackjack games.  

This is because live dealer casino games can allow you to see the action much more clearly, so it might be possible to keep a tally of the cards that have been dealt. 

If you’re heading to one of the many great casino sites to play blackjack then you might want to check out the benefits of card counting.

If roulette is the game you choose to compare casino sites against, then we recommend that you try out a few of the best roulette betting strategies

While this won’t guarantee to increase your chances of winning, at worst it’ll mix up your gameplay and keep things interesting. 

How to find the best online casino sites for poker

Poker is possibly the most popular card game on the planet. It’s a billion-pound industry with countless incredible events, celebrity players, and some great places to play it online. You can find the best places to play this great game by checking out our guide to the best live dealer poker sites

Casino sites are among the most popular places to play poker and for the best ones to stand in comparison to their rivals they need a great range of games.

It’s this point on games that’s so important when comparing casino sites for their poker offering. This is because poker is the casino game where gamblers have the most control over the outcome of events.

The reason players have more control in poker games is twofold. 

Firstly, you play against other players. This takes away the house edge because the casino sites aren’t competing against you to win. 

Secondly, skill matters a lot more in poker because the betting decisions you make during games are affected by your mastery of the game – not by the pull of a lever using an RNG (random number generator), like in slot games. 

There are many different types of poker and one thing we really recommend you do before you play is to get an understanding of the main types of the game – of course, Texas hold 'em is the most popular, but that doesn’t mean it’s the best type of poker for you

Poker is one of the most widely played games on the globe, but it’s often underrepresented at the leading casino sites. 

This was true of the casino sites we reviewed, with the exception of Betway. 

Betway mostly offers video poker games. However, one of the things that makes it so impressive for poker fans is that it has its own cardroom. This means that you can compete against your fellow players in real time.
