These are the 11 best UK casino sites. They offer players the best overall product in terms of support, bonuses, and games.
Shortly, we’ll go into more detail about what makes a great UK casino.
The Best Online Casino Site by Category
We’ve listed the best casino sites for you, but you may want to choose one for a specific reason. We understand that.
You might simply want a good bonus or you may want to register at one of the best mobile casinos as you play on the go.
In the table below, we’ve dug down into those separate choices to bring you the best casinos per category.
| Category | Casino |
|---|---|
| Best for table games | 888Casino |
| Best for poker | Unibet |
| Best for mobile casino | LeoVegas |
| Best casino for slots | Novibet |
| Best for bonuses | Betfair |
| Best for quick withdrawals | STS Casino |
| Best for live casino | LiveRoulette |
| Best new casino | STS Casino |
While some of those mentioned in the table don’t make our best online casinos list, all of them excel in one specific area.
If you’re searching for a site that shines in one particular category, the table above is what you need. Otherwise, refer to our top casinos list.
How We Rate Quality Casinos
Rating an online casino is never a subjective matter here at Casino Deal. We test and objectively review every one and all of the games we mention, thus bringing you only trusted online casino sites and accurate details.
Rest assured our reviews are regularly updated with the latest information. So what makes us consider an online casino as one of the best in the UK? It’s not just the bonuses on offer that’s for sure. They’re important of course, but there’s a lot more to consider.
If a site is listed in our ‘Best 11′, it’s there because it meets our trusted casino criteria and stands up very well compared to those absent from the list.
Our Casino Star Ratings Explained
You may have noticed that every casino we’ve thoroughly tested and reviewed has a star rating of one to five, with five being the highest rating. But what do the star ratings mean exactly? Let’s explain.
Five stars – The casino satisfies all of the questions we ask when reviewing them. It’s not easy to achieve a five-star rating, but those with top marks are the best the UK market has to offer.
Four stars – One with a four-star rating excels in most areas. The odd feature is not quite as good as their five-star counterparts, but they’re still a top UK casino.
Three stars – Don’t discount these casinos. They’re good, but the rating indicates they impress in certain areas. For example, a casino might not offer many payment options but mobile gaming with them is great.
Two stars and below – These casinos lack in a number of areas on our checklist. They might have scored higher previously, but we’re always looking to give honest, up-to-date reviews of each site.
Which Games are Available at Casinos Online?
The games on offer will be an important consideration when choosing your preferred site. Some UK casino games are too good to ignore whereas others are pretty poor. A favourite among many players is online slots, which is why you see so many of them!
All of the UK online gambling sites that made our best casinos list offer a vast number of games, including:
- Slots
- Table games
- Live casino games
- Poker
These can be enjoyed on both mobile and desktop. You’ll have some top casino sites better for roulette, some with a focus on being a blackjack casino, and others known for their fantastic video slots.
The choice is yours depending on your interests. Let’s expand on a few for you.
Popular Slots
The best casino sites will have an impressive range of the online casino slots that will keep you entertained.
The most popular slot sites offer excellent bonus rounds and bonus spins as well as having very good payout rates for players. The better ones to play are those that keep that enjoyment factor going.
From standard games to the best progressive jackpots in the UK where you could win millions, some of the most popular slots include:
- Book of Dead
- Street Fighter II
- Starburst
- Age of the Gods
- Mega Moolah
In terms of popularity, Starbust and Book of Dead lead the way in the UK as they’re always attached to free spins bonuses. They were created by software companies NetEnt and Play’n GO, two of the best casino game providers for online players to consider.
Engaging Table Games
Table games are an exciting part of a casino and it’s where you tend to find the higher Return to Player (RTP) percentages.
The best casinos understand that some players like to play slots or poker and others prefer roulette or blackjack, which is why they cater to all types of players.
If you add in baccarat, that makes up the top three alongside roulette and blackjack in terms of the most popular table games at a 2021 casino.
They also have numerous variations so that you can enjoy a unique betting experience on each table.
You’ll have different betting limits too, so one roulette table might have a minimum bet of £1, whereas another has a minimum bet of £10. They cater to casual players and high rollers.
Don’t worry if roulette, blackjack or baccarat don’t appeal to you; there are plenty of other options available such as Sic Bo, video poker, or online craps.
Live Casino Games
To rank towards the top, you need to provide players with one of the best live casino studios.
The best will probably offer live table games from Evolution Gaming as this software provider is very popular at UK casinos, but NetEnt and Playtech are strong alternatives that many other top casino sites offer instead.
There’s even in-game live chat if you wanted to mingle with other players or the live dealer whilst playing some immersive roulette or Monopoly Live.
Live dealer games are instantly available, which is great from a player’s point of view as you just want to deposit and play.
We’ve got a page exclusively for online UK live casino players, which covers all of the variations available for those who love that realistic feel. It’s worth noting, though, that it’s always the quality of the game that’s important to the top online casinos rather than the amount they offer.
Get Bonuses at Casino Sites
We cover the best online casino deals in great detail throughout this website, making sure you have the best information possible.
There are welcome offers for new customers, deposit and no deposit bonuses as well as reload promotions for existing customers. Not forgetting bonus spins and free spins as well as VIP perks for the high rollers and loyal clientele.
If you want to learn more, check out our top casino bonuses page. We go into great detail there.
What Are Wagering Requirements?
In simple terms, wagering requirements are where you need to rollover the bonus amount (and sometimes the deposit amount too) before you can withdraw any winnings.
We break the T&Cs down for you in each UK casino review so that you can understand them fully. They’re easy to understand once you get your head around them.
A good way to know if the wagering requirements of a bonus offer are any good is to compare them against another online casino’s promotion.
Some of the best casino sites have no wagering requirements on bonuses too! They’re rare but they do exist.
UK Online Casinos with the Best Payouts
If you’re playing with real money, it makes complete sense to target a casino online with the best RTP payout percentage.
What is RTP I hear you ask?
Return to Player (RTP) essentially refers to how much will be paid back to players on a casino game over a certain period of time.
The higher the RTP, the more money will be returned to players overall. This will require a large sample size of course, due to the variance when dealing with random number generation.
Here are the percentages of the best online casino payouts from some of the top UK sites:
| Casino | RTP % |
|---|---|
| 888Casino | RTP % |
| LeoVegas | 96.87% |
| NetBet | 95.63% |
| bet365 | 96.54% |
| Betfair | 97.14% |
| Unibet | 97.45% |
| William Hill | 96.05% |
Although the percentages won’t tell you if and when you’re likely to win, it illustrates a level of trustworthiness as well as giving you important information on casinos that offer the best value.
Remember, the beauty of RNGs is that even if you win big once, you have exactly the same chance of winning big again straight after. It’s always random and fair.
Choose a Casino Site with Fast Payouts
An important factor when choosing a casino in the UK is which methods of payment they have available and how fast you can deposit and withdraw.
You’re fine in the UK with deposits, they’re immediate most of the time, but withdrawals are certainly not instant. This is because of KYC and money laundering security measures in place at all online casinos.
If you want your funds as quickly as possible, we’d recommend using an e-wallet.
The likes of PayPal, Apple Pay, Skrill, and Neteller are often seen as the quickest ways to get your winnings. It’s usually a withdrawal time of 2-48 hours depending on the casino.
One thing to watch out for with e-wallets, though, are the fees. The best sites will waive them, so that’s not a problem, but keep an eye on the newer casinos.
Award-Winning Casinos
Winning an award in the industry instils confidence from a player’s point of view. If a casino has won an award then they must be pretty good, right?
There are a number of prestigious UK casino awards that recognise brilliance across the industry, including:
- EGR Awards
- IGA Award
- Global Gaming Awards
- Global Regulatory Awards
- Gaming Intelligence
If an online casino has picked up one of these awards, it reaffirms their status as a top casino. They’re not just handed out to anyone. It takes effort, innovation, and excellence to get an award.
You also have to be a trustworthy and reputable UK casino to receive one.
What Makes a Safe Online Casino?
Safety is an extremely important factor for players looking to bet at any online casino in 2021. Below lists exactly what we consider to be the key points around safety and security when searching for the best casino sites:
- Licensing
- Random Number Generator (RNG)
- Software
- Payment methods
- SSL encryption
- Site ownership
- Frequent audits
- eCOGRA
Licensing – Every UK online casino must hold a license.
Random Number Generator (RNG) – Every UK casino site will use an RNG to ensure fairness so that every player has an equal chance of winning.
Software – All of the software used at quality casinos in the UK will be from reputable and trusted software providers.
Payment methods – All deposits and withdrawals must be made securely using the highest level of encryption. None of your personal data will be shared with third parties.
SSL encryption – This is a Secure Socket Layer encryption method that’s used to make sure the communication between your device and the online casino is protected.
All licensed casinos in the UK operate with this in place, so you can rest assured your online banking information is safe.
Site ownership – There are many sites owned by large and long-established gaming groups. If the company who owns the site is fairly new, we’ll do all of the research necessary before recommending them to you.
Frequent audits – Third-party companies will regularly audit an online UK casino to ensure it’s doing everything above board. They’ll undertake a full security check and make sure the software and the RNGs used are fair and safe.
eCOGRA – It stands for e-Commerce and Online Gaming Regulation and Assurance.
As stated on their website, they see themselves as the independent standards authority of the online gambling industry, specifically overseeing fair gaming, player protection and responsible operator conduct.
Licenced with a Trusted Authority
As a UK casino player, when you visit a casino online, please make sure that it is licensed by the UK Gambling Commission (UKGC).
The UKGC is the body that grants licences to casinos that want to accept wagers from players in the UK.
They regulate the market and ensure each and every UK casino is compliant. This means that you can use any of these safe and secure sites knowing that the games you play are fair and your personal data is protected.
Other trusted regulatory bodies you may come across when playing at different sites include:
| Country | Regulatory Body |
|---|---|
| United Kingdom | UK Gambling Commission (UKGC) |
| Isle of Man | Isle of Man Gambling Supervision Commission (GSC) |
| Channel Islands | Alderney Gambling Control Commission (AGGC) |
| Malta | Malta Gaming Authority (MGA) |
| Gibraltar | Gibraltar Regulatory Authority: Gambling Commissioner |
You’ll notice the likes of Malta and Gibraltar in the above table. We’ve mentioned these as some casino sites hold licenses from multiple authorities, which further enhances their trustworthiness as they’ve fulfilled the safety and security requirements in additional jurisdictions.
As well as game fairness and data security mentioned above, how else does the UKGC protect players?
- Complaints and license imposition
- KYC verification
- Responsible gambling
Complaints and license imposition – If you’ve come across a problem such as a broken game, disputed offer terms, or a game software issue, there must be a complaint process available to you from the online casino you’re playing at.
Unresolved disputes can be referred to the Independent Betting Adjudication Service (IBAS) which is an Alternative Dispute Resolution (ADR) service.
The UKGC can also remove licenses and impose fines and sanctions on casinos in the UK if they violate any terms of service.
KYC verification – All UK casinos must get players to confirm their identity before they can withdraw any funds. It’s an important step to identify anyone under 18, potential money launderers and problem gamblers.
Responsible gambling – UK casinos with a valid licence must have responsible gambling measures in place such as timeouts, self-exclusion and deposit limits.
Promote Responsible Gambling
If anyone falls out of love with an online casino and loses that enjoyment factor, it’s important for them to understand that they have somewhere to turn if they need help. It’s important that UK sites make it easy for players to access the information they may need about this.
There are many organisations that can provide essential guidance where needed. The best online casinos, and us here at Casino Deal, have a dedicated responsible gambling page and the BeGambleAware logo in the footer of the site.
Independent charities like BeGambleAware and GamCare offer free and confidential help for anyone who is worried about their own or someone else’s gambling.
How to Join an Online Casino
If you’re new to this, it helps to understand the process you need to go through to open an online casino account.
