Best Casino Sites for 2021 in UK

The online casino space is huge. And when we say huge, we mean that there are now hundreds, if not thousands of casino sites active in the online arena.

On the one hand, this means that you will have access to heaps of online bonuses if you are yet to open an account with the operator in question. On the other hand, this can make a challenging process in your hunt for the best casino sites.

In this article, we at explore the best casino sites of 2021. Our expert reviewers have focused on what matters – including key metrics like Gambling Commission regulation, heaps of everyday payment methods, low house-edges, and generous bonuses and promotions.

How to Find the Best Casino Sites UK?

If you’re wondering what the best casino website UK of 2021 is, there isn’t a one-size-fits-all answer to this question. The reason for this is that no-two casino sites are the same.

For example, while one platform might be the best casino UK online for house-edges and customer support, another might excel in the bonus department. As such, you need to assess the factors that are most important to you when exploring the merit of the UK top casinos.

As such, be sure to make the following considerations in your hunt for the top UK casino sites of 2021.


At a minimum, top online casinos UK will always hold a regulatory license, which must be with the Gambling Commission. This offers you a range of regulatory protections that would otherwise not be available at an unlicensed casino.

At the forefront of this is the segregation of player funds. In other words, the best online gambling sites UK will keep your money separate from their own, which is crucial.


The best UK casino sites will always offer a sign-up bonus of some sort (check our list of the best casino bonuses UK). This usually centres on a matched deposit bonus, meaning your initial deposit will be boosted by a certain percentage.

For example, if the top casino UK offers a 100% matched deposit bonus – and deposit £300, you will start off with £600. With that said, best casino sites with free signup bonus in 2021 offer matched deposit bonuses of 200% – or even 300% of your first deposit amount.

Payment Methods

Top casino sites UK will offer a plethora of popular payment options to choose from. Top-rated methods include a debit or credit card, as deposits are instant and free. Some casino sites will also offer popular e-wallets like Paypal and Skrill. We also offer a selection of pay by phone casino sites that allow you to deposit via your mobile phone bill/

Not only do e-wallets add an extra layer of security of your personal information, but you will also benefit from instant and free deposits. The best online casinos UK will also cater to those of you that wish to deposit funds with a bank transfer, and of course – the ability to fund your account with your mobile phone.

Gaming Suite

Top online casino sites UK will offer a highly extensive gaming suite. This includes popular and well-known table games like blackjack, roulette, and baccarat – as well as live casino dealers. In the new UK slots department, the best casinos UK will offer hundreds of individual titles – including that of progressive jackpot games.

When it comes to software providers, the best online casino UK will only host casino games from the most trusted developers in the gambling space. This should include well-known providers like Microgaming, Playtech, and NetEnt.

Withdrawal Times

While deposits are typically instant when gambling online, the top casino sites online will offer super-fast withdrawals, too. While this will never be instant per-say, we at find that the best casino site UK will process withdrawal requests within 24 hours.

As a side tip, if using a trusted e-wallet like Paypal, the best UK online casinos will often release your funds within a few hours.

Customer Support

It is important to stock with gambling platforms that offer top-notch customer support. We find that the best casino sites in the UK offer a 24/7 customer service department across multiple channels. This should include live chat, email, and telephone

Crucially, it’s all good and well if the casino offers support around the clock – but, you’ll be left disappointed if the platform makes you wait for long periods of time before connecting you to an agent.

As such, the best new casino sites UK will have a sufficient customer service team that ensures you never need to wait for more than a few seconds to get assistance.

In order to find the top UK casinos, you are best advised to perform some in-depth research on the platform before opening an account. With that being said, this might not be possible if you want to start gambling right now. If this is the case, we would suggest reading the many casino reviews that we have published on our site.

Each review has been compiled by one of our in-house experts.

In doing so, you’ll get a full 360-degree of the top casino online UK sites currently in the market, without having to do the hard work yourself.

It is important to note that our reviews never allow our recommended top UK online casinos to influence our ratings. On the contrary, we at are proud of our longstanding track record in providing impartial, bias-free, and honest reviews to our readers.

How do the Best Casino Sites Work?

If you’ve never gambled at the UK casinos before, knowing where to get started can be challenging. With that in mind, follow the step-by-step guidelines outlined below to start playing at the best casino sites right now!

Step 1. Open an Account

Regardless of which platform you decide to join,  the best casino sites will always hold a regulatory license and thus – require you to open an account. The process rarely takes more than a couple of minutes, and merely asks for some personal information.

This includes your:

  • First and Last Name
  • Home Address
  • Date of Birth
  • Nationality
  • Mobile Number
  • Email Address

The best casino sites will also ask you to choose a username, password, and secret question/answer.

Step 2. Deposit Funds

You will now need to deposit some funds. As noted earlier, the best casino sites will give you a range of payment methods to choose from.

This should include:

  • Debit Card
  • Credit Card
  • Paypal
  • Skrill
  • Neteller
  • Paybyphone
  • Bank Transfer
  • Paysafecard
  • Pre-Paid Card

Unless you opt for a bank transfer, the best casino sites will credit your deposit instantly.

Step 3: Verify Your Identity

In order to remain compliant with anti-money laundering laws, the best casino sites will need to verify your identity. Gone are the days when the platform can do through third-party sources. On the contrary, you will need to upload a copy of your passport or driver’s license.

As the best casino sites take their regulatory responsibilities very seriously, you might be asked to upload a proof of address, too. This can be a utility bill or bank account statement.

Step 4: Explore the Gaming Suite

Now that you have a fully funded account – and submitted your verification documents, you can enjoy the gaming suite. Online casino sites UK typically offer thousands of popular games across multiple departments.

This includes table games, video poker, slots (check our selection of best UK slot sites), progressive jackpots, scratch cards, arcade games, and live dealers. The best UK online casino sites will often host a fully-fledged sportsbook or live poker room.

Step 5. Withdraw Your Winnings

Once you get to the point where you want to withdraw your winnings, you’ll need to head over to the banking department of the site. You will need to withdraw at least the deposit amount back to the same card that you used to fund your account.

For example, if you deposited £400 with a debit card and you wish to cashout £750, you will need to withdraw at least £400 to the card. However, UK online casino sites will then allow you to withdraw the remaining £350 to another method – if this is something you wish to do.

A few important points to note when withdrawing cash from the best casino sites UK are:

  • You will need to have had your identity verified before cashout request is permitted
  • It can take anywhere from a few hours to a couple of days for the casino to process your withdrawal
  • You will then need to wait for the payment issuer to credit your withdrawals

In a best-case scenario – and assuming you are using the biggest online casinos UK that accepts Paypal deposits, you could get your winnings paid out on a same-day basis.

Bonuses at the top 10 Online Casino Sites UK

If you are just starting out in the world of online gambling, you will literally have hundreds of casino sites to choose from. In the vast majority of cases, casino sites will offer you a welcome package as a means to entice you to their platform.

As we briefly mentioned earlier, this is usually in the form of a matched deposit bonus. For example, let’s say that the best online gambling UK site offers you a 300% deposit bonus of up to £900. If you were to maximize the bonus offer (which you always should), you would get a £900 bonus for depositing just £300. As such, your starting balance would amount to £1,200!

Alternatively, the best casino sites sometimes offer bonus spins or free spins.

As lucrative as welcome packages are for new customers at online casinos, you will need to meet a few terms and conditions before you are permitted to withdraw the bonus funds out.

Here’s the lowdown:

Wagering Requirements

If the casino didn’t install a wagering requirement, this would allow you to withdraw your bonus funds straight out. In the example above, this means that you would be able to withdraw £1,200 back to your debit card, even though you only funded your account with £300! As you can appreciate, this is not a viable model for any business.

The wagering requirement refers to the amount you need to stake at the casino before a cashout is allowed. Sticking with the same example as above, let’s say that the wagering requirement is 10x, which is based on your £900 in bonus funds – plus your £300 deposit. This means that you would need to stake £12,000 at the casino before you can withdraw the bonus funds out.

Eligible Games and Contribution Percentage

When you get around to using your bonus funds, certain games will be excluded. This is usually progressive jackpot slots, as the title will likely be held at hundreds of other casinos. As such, your chosen top online casino UK will not have full control over the pot, which is why you will be prohibited from using your bonus money.

Other games – such as roulette and blackjack, are usually permitted within a bonus promotion. However, you will all-but-certainly find that your stakes only contribute 10% towards the wagering requirement. So, if you staked £500 on ‘19-36’  – only £50 word get knocked off your wagering target.
