What is the best online casino in the UK? This is a great question, and it’s one we hope to answer in our comparison. On our website, you’ll find comparisons based on free spins, bonuses, and rating. With some offering the chance to get started with no deposit, you’re sure to find a platform you love with our extensive resources.

In addition to this, the lists themselves are put together cleverly so you can choose a casino and watch an overview of the bonus offer. In case you need any more help, keep reading!

First-Time Casino Users

First and foremost, we remind you that using a casino online is an economic activity. With all website and platforms, they come with all sorts of terms and conditions, and it’s important to understand them. In case you were worried, our own platform adheres to all the UKGC rules and regulations. We all want a safe gambling environment, and this is one way to achieve it.

Testing a Casino

Often, we’re asked about the ‘best’ online casinos in the UK, but it actually comes down to personal preference most of the time. No matter your experience, we highly recommend trying all the casinos in our list because this gives you an opportunity to think about which platforms you enjoy and which you don’t.

While some will feel great at first, you’ll soon notice features you don’t like such as a slow withdrawal process. Of course, you don’t want to waste lots of money, and this is where no deposit bonuses come in; take advantage of bonus spins, free spins, and extra spins.

With all the names on our list, they’re tested frequently. With this in mind, you can be sure they’re the best around; it’s up to you to find your favourite. If you test a name in our list and have a poor experience, please feel free to let us know. The last thing we want to do is recommend a poor service.

Why waste time searching for a reliable service, and potentially going through negative experiences, when others have done all the testing already? At all times, we aim for accurate information regardless of whether you prefer no deposits bonuses, casino bonuses, or something different altogether.

Unfortunately, not all casinos will offer no deposit bonuses, and this is because of the growing number of bonus abusers. This being said, the reason that we’re one of the best guides in the UK is that we can often arrange special no deposit bonuses on your behalf.


Are all online casinos legal in the UK?

No, online casinos need a UK Gambling Commission license to operate. In order to check, simply scroll down to the bottom of a lobby and look for a license number.

Do online casinos accept bitcoin?

As time has gone on, we’ve seen the introduction of cryptocurrency online casinos and these accept bitcoin. You’ll find examples with a simple search online, or we do also offer some that allow Bitcoin for depositing.

Are online casinos legitimate?

The internet can be a dangerous place, so we recommend checking all potential casinos before depositing money. For example, you can look at the footer of their website for a license number and licenser logo. Legitimate services need to be registered with a gaming regulator.

Do online casinos accept PayPal, Skrill, or Neteller?

In all countries where the license holder has operations, PayPal will be an option. Other than this, no other services will be offered by PayPal because of their own regulations.

With Skrill, it’s actually become more and more common as a payment method in recent years. Despite this, bonus abusers have caused problems, and this is why there’s normally a bonus exclusion.

Finally, Neteller is another eWallet and therefore another popular option with several online casinos. Again, the issue with bonus abusers has led to a bonus exclusion.

No Deposit Free Spins in 2020

In the UK market especially, free spins have become something of a phenomenon. Since no deposit free spins are almost as popular as slot machines themselves, we have a page dedicated to them. As long as you’re in the UK, you’ll have an opportunity to utilise the brilliant no deposit bonuses.

Alongside other fun free casino games, you will be presented with free spins from Microgaming Casino, Net Entertainment, and plenty of other big names. In 2020, the majority of no deposit bonuses come from NetEnt games and this is because the price is cheaper than most other providers.

If you want to play with free cash, we also have a page dedicated to this (you’re in great hands here!).

Join Our Online Casino Class

We understand that not everybody has experience with online casinos, and this is why we launched the casino school. Starting with basic introductions, you’ll learn everything you need to know to get started. In fact, we’ve even had experienced players get value from the class.

Once you’ve completed the class, you’ll get a fantastic reward (as well as advice that will stick with you as you join the world of online casinos!).

Getting Started – Three Top Tips

Here’s three top tips to get started with online casinos;

  • Register and Test – Before depositing any real money, play around with a website and get to grips with how it all works; issues like slow page loading times can be picked up almost instantly.


  • Try a No Deposit Bonus – Don’t forget, we’ve gone to the effort of finding the best no deposit bonuses so that you don’t have to.


  • Deposit – Once you have a handful of contenders (i.e. our list of the best online casinos UK), try depositing and enjoying the welcome bonuses on offer. Soon enough, you’ll have a favourite.

Why Choose Us?

With experience in the field, we’re a reliable source of information with regards to all things betting and online casinos. We love to help those with very little experience to get started, as well as those with experience to get even better and find games that they really enjoy. It doesn’t matter whether you’re a casual bingo player or a serious poker player, we have the resources to help.

Furthermore, we’re a professional service which means you can always rely on our guides and campaigns. In case you needed any more motivation to choose us, here are three reasons!

Exclusive Casino Bonuses

Firstly, we’re incredibly lucky and proud to be in a position to offer exclusive bonuses and campaigns. In addition to the daily updates, these campaigns will also be shown in our fantastic newsletters. Simply opt-in to our newsletters and watch the great campaigns and bonuses roll in.

Since many players find their ideal platforms through our guides, we have the opportunity to offer unique deals. We’re helping casinos by generating custom and improving reputation, so we actually have a strong say on what bonuses we want to offer.

As we continue to work with casinos, your experience will only ever improve. For even more casino bonuses, visit

Cashback Deals

As the second reason, we’re still in early days with the cashback systems but it’s something that will be a strong part of our service soon. As long as you go through our recommendations and register for your account this way, simply file an application (this isn’t possible with all casinos just yet).

To apply for our cashback program, visit the ‘Contact Us’ section of our website and send a message. As long as we have your deposit/game activity and username, we can process the request and then get back to you as soon as possible.

Tailored Assistance

As casino guides go, we are very much focused on customer service. Rather than just providing generic advice that could be found anywhere, we also like to go the extra mile with personal service. With a super VIP rewards system, we think it can rival the VIP loyalty programs found with casinos themselves.

For those on a bad run or losing lots of money, we can help with a nice bonus. As we check stats together and talk through the situation, you walk away feeling better and more confident. We’re always looking to help users with tips.

New UK Online Casinos

As you may have noticed yourself, the UK market seems to be welcoming new casinos continually. There’s one reason why this is good news; because the UK does casinos well. Also, as competition increases, we’re more likely to enjoy more no deposit bonuses as they attempt to attract new customers.

For some, they see the added choice as a distraction and all they really want to do is build loyalty with one brand. The more loyalty you build with one casino, the more likely you are to enjoy the many perks. Keep an eye on our extensive lists and look out for new names that might enter them.

Payment Providers with Casinos

If you’re choosing a new online casino, one of the advantages compared to many years ago is that most provide a number of payment methods. These days, the most popular two are MasterCard and Visa. Sometimes, payment methods have fees, and this has led to many choosing eWallets. What payment methods will you find? In truth, it’s normal to find a collection of the following;

  • MasterCard
  • Visa
  • Maestro
  • Visa Electron
  • Neteller
  • GiroPay
  • Skrill
  • Zimpler
  • EcoPayz
  • Trustly
  • Paysafe Card
  • SoFort Banking
  • EntroPay

Playing on a Mobile Device

Thanks to the introduction of mobile devices, we no longer need to play online casinos on desktop computers, and this has been a big step forward recently. Fortunately, online casinos have kept up with this trend. Regardless of whether you enjoy table games or slots, they can be accessed via your preferred device whether you like the traditional computer, a tablet, or even a smaller screen in your smartphone.

Guide to Licensing

If you’re worried about licensing and you want to stay with an accepted and regulated service, we praise your awareness. In the UK, the most recognisable iGaming license comes from the UK Gambling Commission (UKGC). Since the UK has always been advocates for a regulated sustainable market, the UKGC license remains as one of the biggest and best in the world today.

Taking the example from the UK, many other countries are now catching up and this has been a key development in recent years.

International iGaming Licenses

Alongside the UKGC, there are three other well-known and recognised iGaming licenses that are used by casino websites;

  • Malta Gaming Authority (MGA)
  • Spelinspektionen (SI)
  • Curacao Gaming License (CGL)

In Europe, these are now the most-used licenses for casino websites. Why? As well as being established, they often allow the targeting of unregulated markets.

Live Sports Betting Online

Don’t worry, you aren’t alone if casinos aren’t your thing. We know many of you will prefer sports betting, and this is why we’re also passionate about helping this market. With current sports betting bonuses, we highly recommend looking in the betting section of our website to get started.

If you’re a beginner to all forms of gambling, stick with the casino first because this is where most of our attention goes (and you also don’t need any skill to get started!). In truth, the learning curve is less steep on the casino side.

Reviews of Online Casinos

How do we determine a ‘good’ online casino from a ‘great’ online casino? First and foremost, you shouldn’t find any bad UK casinos on our website. If you do have a bad experience, tell us immediately. If you see an online casino listed on our platform, you can be confident that it’s been tested by not only us but other casino guides too.

If you’re interested in how we consider online casinos for recommendation, we pay attention to the following;

  • The registration process on both mobile and desktop
  • The no deposit free spins and extra spins available through special offers
  • Their acceptance of UK players for bonuses (some are restricted to other countries)
  • The games available through the casino lobby
  • The depositing and withdrawing processes

If we’ve checked all of the above and the experience is a smooth one, we then think about aesthetics and the experience as a whole. From here, we start to build an idea of whether a platform is worth your time or not.

At this point, we want to note that we don’t just give our approval to every platform. As mentioned previously, customer experience is at the forefront of our thinking at ALL times. If a website has our seal of approval, it has been checked extensively and we have verified them as a good casino. Not only do we have a list of reliable services, the casino themselves can place our seal on their home page, and this allows for a transparent experience for all.

If you have complaints, please feel free to send us a message. Since our seal has some sway in the industry, casinos are happy to work with us towards resolutions quite often.

Different Games in the UK

After choosing a casino, another difficult decision normally comes when faced with the sheer number of games available on these platforms. Depending on the website, you’re likely to see a combination of;

  • Baccarat
  • Blackjack
  • Slots
  • Video Poker
  • Craps
  • Roulette
  • Jackpots

Get Started Now

We’re always looking out for brilliant bonus offers and our own platform is always updating. Just like Casino Gods recently, new English platforms are always entering the market. Before letting you get on with your day, we want to touch briefly on the mechanics of a no deposit bonus offer.

How does it work? Just as the name suggests, you don’t need to deposit to get started. Instead, register with a few details and then confirm your email address. In terms of testing a casino platform, there’s no better way than with free spins and other no deposit bonuses. You don’t have to enter your card details, there’s no risk at all, and you experience how it all works.

Be sure to stick around and save our homepage to your bookmarks to stay up to date with all the guides and information you’re likely to need. Also, we love hearing your feedback (whether it’s positive, or perhaps you have some constructive criticism for how our website could be run more effectively). With feedback, we have the information we need to continually get better.

If you want to get in touch with feedback or even a question, simply visit the ‘Contact Us’ section of our website to get started. Otherwise, we hope you find an online UK casino that matches your needs. Remember, all the platforms we endorse have been tried and tested. Therefore, you’re likely to have a positive experience both now and long into the future!
