Just in case you’re from the UK and you’re looking for the best UK online casinos, look no further as we list the top 10 UK online casinos. The 10 UK casino sites listed are the best 10 online casinos for UK players. Only the trusted high rated casinos are listed!

UKIt takes more than just a flashy interface and a solid collection of games to intrigue seasoned UK online casino players. When playing at a UK casino site, there are things that may look right on the surface that seems to take on a whole new face once we scratch the surface a little. What UK online casino players want as clients, is more than just a bonus and a few free spins before waving goodbye.

The true value found in playing online games should be with UK online casinos that reward existing customers as well as new players. There is nothing worse than feeling great when you sign up only to be forgotten about once a casino has signed you up and effectively reeled you in.

Welcome bonuses tend to be the way in which casinos can get our attention, and these are getting more and more competitive. This is down to the number of UK online casinos operating these days, which drives that push for market share. New and experienced UK casino players will be offered the sun, moon, and stars to join a casino site, but must decide for themselves if there is any chance of a long-term relationship. The more experienced players should understand that there are small things to look out for which can make an internet casino a long-term home, rather than a stop-gap.

In this UK casino guide, we will take a look at everything a UK casino player needs to know when playing online.

How UK Online Casinos Work?

Not all casinos are created equally. You might trust yourself to have the knack of being able to identify a poor casino from a good one at a glance. It is fair to argue against anyone really understanding how good a casino can or cannot be without research. Many UK casinos can appear to be much better than they are by adopting an approach that veneers the crap with a nice and shiny design and a few decent games.

On the flip side, the modest-looking casino you would reject at first glance could be awesome. The UK’s best 10 online casinos are those which we would consider as having a more refined and powerful all-around product. Think a massive range of slots, an excellent variety to their games, a solid sportsbook, and many live casino games. Factor in a number of banking options and a solid customer support function and these casinos throw down the gauntlet to competitors.

UK Online Casino Laws and Regulations in 2021

UK Gambling Commission

The first duty of any online casino player is to play legally. Legal play is a safe play. And illegal play is the opposite – playing at licensed sites is the first step you should take in having a good, safe, enjoyable UK online casino experience.

And it’s relatively easy to do.

Any UK online casino site worth its salt will show you its licence with pride. Most UK casino sites list the full details of the license and there should be a link to the site of the UK Gambling Commission so you can check it for yourself.

That’s something we do on your behalf whenever we review, recommend, or so much as look at an online casino website. Feel free to do the same when you use a new one.

UK online casino laws and regulations have been stable for a while. But they could be subject to change, so keep in mind that you need to keep abreast of the laws.

The laws are there to protect you, so make sure you follow them.

The most recent changes have been the banning of credit card gambling. That might be inconvenient for some players, but you can certainly see the dangers of playing with borrowed money.

The biggest rule to be aware of is age verification because you will need to prove – usually with official documentation – that you are over 18 if you want to gamble at UK online casino sites.

The regulations also provide rules about how games must operate and the percentage of the money that is spent on them that they should return to players. This theoretical return to player is a crucial figure for players who want to make their money last.

The UK Gambling Commission also ensures that players can easily find information about finding help if they do feel they need it, and that’s something else to take seriously, and to be grateful for.

Always keep it safe and always keep it legal.

Ways to recognize the Best UK Online Casinos

These brands have more capital to invest in advertising and bonuses, which will typically mean that they have a larger player base. A professionally designed website, strong regulations and licenses, also contribute to making these sites as successful as they are. The strength of the biggest players in the online casino sphere is their ability to tackle almost any aspect of online casino gambling.

When players opt for new UK online casinos to play under, they should first be considering these top 10 UK online casinos we list. They are literally what other smaller and sometimes shadier casinos will compare themselves against. You can usually identify the size of a smaller casino with their range of games and payment options, in addition to their bafflingly unrealistic bonus offers. If you see a new player welcome offer for thousands of pounds, ask yourself how they can afford to offer such sums of cash. You will quite often find the answer in the wagering requirements and T&C’s.

Despite all logic, many players fall for these unrealistic offers. Even if they manage to win from the bonuses they gain from some of the more nefarious companies out there, they may find that their accounts get closed and they end up with nothing.

It pays to know who you are dealing with.

UK Casino Bonuses & Promotions

There are not many people in the UK that would reject the chance to have something for nothing. While one of the 48 Laws of Power is to “despise the free lunch,” this clearly does not apply to online casinos. Nor should it, as bonuses, for the most part, are not always as “free” as many casinos would like to have you believe. While some are excellent value and well worth it, others leave a lot to be desired.

With competition between online casinos in the UK at an all-time high, these operators must find new ways of getting as many players as possible through the door. The most common way a casino will do this is by offering you a deposit bonus of some sort. It is important that you do your research on a casino to see what they offer their existing customers, too, as some pretty much forget you exist once you are signed up.

There are a ton of different types of UK casino bonuses that are typically offered to players, so make sure that you are eligible to claim as much as you can get. While pretty much every player with a valid payment method can claim a welcome bonus, things can get a little trickier after that. Like you notice at Christmas and birthday times with your aunts and uncles, some are more generous than others. It is exactly the same in the case of UK casinos.

The UK Casino Welcome Bonus

UK casino welcome bonuses are designed to get you to sign up to a casino and can be fair to pretty generous indeed. You can get your hands on free casino cash or a combination of chips, free spins and more, just for signing up for that casino. Online casinos typically match your first deposit or can double or treble it.

There is no set amount for a welcome bonus, although this will come down to the casino itself, and how much they are willing to offer. A casino may have a tiered bonus system to get you to make a larger deposit amount by offering more for your money. The typical way in which casinos do things is to offer a flat new customer bonus unless you are VIP or a high roller.

Bonuses for casino players can generally be used in any game. But, wagering amounts may not be the same in terms of what they contribute to turning it over. From the outset, these type of bonuses are advertised as having turnover requirements and wagering amounts. But sometimes, the small print is not so obvious. Check these out before you agree to take the offer.

There are many different types of casino deposit bonuses out there, but online casinos do tend to offer deposit bonuses to new players for the most part. Existing customer bonuses tend to form part of daily, weekly, or monthly offers. As mentioned above, there are always terms and conditions built into bonuses. It will be up to you to make sure that these are satisfactory for you before you accept any new player offers.

High Roller Gambling & VIP Casino Bonuses

High roller casino bonuses are given to players who are likely to spend a lot of money at a casino. In order to get your hands on these offers, casinos require customers to contribute serious revenue for them. High rollers will always receive better offers, fewer restrictions on bonuses, cashback, points, holidays and a number of other incentives.

VIP high roller casino bonuses are generally given to those who have proven themselves over a number of months or years to have a propensity for depositing large amounts and showing consistent loyalty to the casino. VIP players get assigned account managers and special representatives. There are sometimes tiers in a casino that allow players to move up ranks over time in order to get these offers.

UK Casino Software Developers

Many seasoned players will agree with the following statement: a casino can only be as good as the software it operates with. When choosing a new UK casino to play in, check for the notable names, or those considered as the big UK casino software developers. If companies like Microgaming, NetEnt, and Play n Go feature prominently, then you can generally be assured that they are reputable. The range of casino games and slots can go a long way towards influencing players, and rightly so.

This is certainly something that rings true for us. Quality is always better than quantity, and there is nothing better than finding a top online casino that has both to offer its players. Sometimes the size of a casino’s catalogue of games does not have to be huge for them to be a top gambling site, but there has to be a decent size of games, right?

Terms & Conditions: A Must Read

Every online casino player should make themselves as familiar as possible with how the casino operates. Reading through their terms and conditions is crucial. The majority of complaints made against an online casino come down to players not reading and understanding their terms and conditions before playing. This is a massive problem, but one which can easily be avoided, for the most part.

Every player has to read through terms and conditions if they want to consider themselves as smart and savvy, especially when it comes to protecting themselves. Understanding the list of the terms highlights anything which a player may find unfair or unreasonable, especially if it affects your ability to win. The wagering restrictions on payouts and bonuses should play a major factor in any player’s decision to sign up to a particular site, even if they do get that far in the first place. Always play at safe online casinos.

Casino Banking Options

There is a wide range of possible casino banking methods out there, and the average casino should offer most of them. It is important that you have a means not just to deposit with, but also to withdraw. Credit cards like VISA, MasterCard, debit cards, bank transfer, e-wallets like PayPal, Skrill, Neteller, voucher options, PaybyPhone and many more are typically widespread in most UK online casinos.

You do not want to get caught out without a decent range of payment methods, regardless of how much you like the look of a casino. Payment methods should always be checked before you start to play with a new gambling site for real money. Deposit methods, withdrawals, processing times should all be important to you when it comes to choosing the best casino.

This information should be found before you start playing, in order to feel confident and assured that you will not effectively be throwing your money away. Different casino sites have different depositing methods, but the international standard should always be found in any top internet casino.

Customer Service & Support

Customer services and support is a very important feature to consider when signing up for a new online casino in 2020. Educated and knowledgeable staff come in very handy when you need assistance. At times when something does not appear right, or you have a slew of questions that the FAQs simply do not cut, you will likely look for assistance.

If there is no contact information or a customer service support function, you are probably best avoiding the gambling site in the first place. Customer service and support can often be an indication of just how far an internet casino will go for its players.

Security: Play at Safe Online Casinos

What players should be looking for are safe online casinos licensed in the UK. SSL-Encryption technology, firewalls, technology to protect players, anti-money laundering measures and proactive customer service and support staff are the difference between a top-class safe online casino and a pretender.

If you ever have any suspicions regarding the security of a site, it is almost always the right thing to avoid them. Always play at safe online casinos.

UK Online Casinos FAQ

Can I Play at Online Casinos in the UK for Free?

Yes! There are many online casinos in the UK welcoming free play, and this means being able to trial games without having to spend a penny. Known as free play demos, the games operate in the same way as they would when playing with real money, the only difference is you don’t get to keep what you win in demo mode. Don’t forget to switch back to real play mode to keep all of your winnings.

Why Do I Need to Verify My Identity?

Verification is required by law and all online casinos in the UK will be required at some point to request identification documents from their customers. Documents will include a recent utility bill as proof of address, a photo of your driver’s license or passport to confirm your identity and a photo of your payment method. If you use a debit card, you can blank out the middle 8-digits of your card for security and peace of mind. When the operator has these, they know that you are who you say you are and that you’re the legal age to gamble.

Why is a Payment Method Needed on a No Deposit Offer?

Payment methods are often needed with no deposit offers and again, this is standard procedure. Your age and identity will be verified by the payment method and will allow you to play with your free play offer. Rest assured, no money will be taken from your account.

What are Wagering Requirements?

Wagering requirements are also known as play through terms and are highlighted as a percentage. For example, 40x means that the bonus amount will need to be played through 40x before a withdrawal will be authorised. A £10 bonus will become a £400 spend under these specific terms.

Do I Have to Pay Tax on My Winnings from an Online Casino in the UK?

No! Anything you win from an online casino in the UK is credited to your account in its entirety. Whether you win £100 or £1,000,000, that sum is tax-free.

What Happens if I Forget My Log in Details?

Forgetting log in details is not uncommon. If you lose your username or password, the online casino will guide you through easy-to-follow steps to gain access to your account. It usually involved resetting your password and this will come in the form of a link being sent to your registered email address. If you’ve forgotten your email address, you could try resetting your password as this usually generates an email with your username attached. If that doesn’t work, you could contact customer support.

Can I Play Online Casino Games in the UK on Mobile?

Online casino games on mobile are extremely popular in the UK and more often than not, an app is not required. Logging into your favourite UK casino is as simple as launching the website via the browser on your device. Use your desktop username and password to gain access to your casino account to start playing slots, live casino games and even progressive jackpot slots.

How Do I Know the Online Casino I’m Playing at is Reputable?

Research can tell you a lot about an online casino brand – one quick internet search will bring up real player reviews on their experience at that casino. There is another way of determining if the casino you are playing at is genuine and that is by scrolling to the foot of the page to view the licensing and regulation information. All UK licensed casinos are provided with an operating number from the UK Gambling Commission. If you fail to spot any details on a current license, stay away!

How Do I Know the Games Are Fair?

Many believe online casinos choose who wins and who doesn’t, but in reality, it’s a sophisticated piece of software that does that. The online casino has no influence over this software and it is independently tested to verify it is random and fair at all times. RNG’s or random number generators are tested to their limits before being installed into games, so you can rest assured all gaming outcomes will be fair and random at all times.

If I Win a Jackpot at an Online Casino in the UK, Do I Receive My Winnings in Full?

The answer to this could be yes and no. If it’s a pre-set jackpot, some operators have terms and conditions that state the full amount will be paid in monthly instalments until it's paid in full. However, this is a rare stipulation. Progressive jackpots from the likes of NetEnt and Microgaming will be paid in full once verification of the win has taken place. Verifying a progressive jackpot win can take up to 48-hours but once done, the full sum will be credited to your online casino account.

What Happens if a Game I’m Playing Freezes?

A common feature for those relying on mobile data but one that won’t see you out of pocket. If a game should freeze while mid-spin, re-loading the page will bring you right back to where you were. The same goes for the free spins bonus, if the game crashes you will pick up where you left off and any winnings that were won prior to the freeze will be ready and waiting to be credited to your account.

Why Do I Keep Getting a Reminder of How Long I’ve Been Playing?

As annoying as this pop-up feature is, it is required by law to remind players of the time they’ve been gambling. Many people lose track of time and as a result, lose a lot more money than they had planned to. A reminder of how long you’ve been playing can help keep to responsible gambling limits. You can set your own reminders from 60-minutes to less or more frequent reminders.
