How to choose the best online casino in the United Kingdom?

Now that you know what our experts say are the best online casinos, it’s time for the next step: decide for yourself which online casino is your number one. After all, it’s more fun to compare casinos based on aspects you find important. You do this by scrutinizing different aspects of a particular casino.

Below we will discuss in detail the main aspects in which United Kingdom online casinos may differ from each other. We will discuss security, the best casino bonuses, online casino games, software providers, payment methods, mobile casinos, customer service and ease of use. Then you’ll know exactly what to look for.

If you want to make a thoughtful choice, it’s best to read on.

🎁 1. Lots of promotions and casino bonuses

At a land-based casino, you get a nice drink upon entry. Think of the welcome bonus as the online version of this. Like drinks, casino bonuses come in all shapes and sizes.

The most sought-after online casino bonus is also the rarest: the no deposit bonus. This is a bonus that does not require you to make a deposit first, 100% free play money. Most legal United Kingdom online casinos require you to make a deposit first in order to claim the free play money.

These bonuses vary greatly between casinos. At the most popular online casinos, the bonus amount is often equal to 100% your first deposit up to £250. This means that if you deposit an amount of £300, you will receive an additional £250 and a total of £550 will appear in your account.

In addition to the popular cash bonuses, some online casinos hand out free spins. With these, you play a number of rounds for free on certain online slot machines. In addition to free spins, casinos usually have some temporary, fun promotions.

An important factor that many new players overlook is the bonus terms. Even if an online casino gives a bonus of £500 or hundreds of free spins, it is of no use to you if it is impossible to clear. Two things to look out for are: the redemption conditions and the games on which the bonus is usable.

 🎰2. Supply of casino games

An online casino is worthless without a nice offer of online casino games. We distinguish three main categories: online slots, card and table games and live casino games. A good online casino has an extensive offering in at least these three game groups.

The casino sites — except Gxmble and Simsino casino — listed in our online casino top 5 list offer at least 1200 different games. However, with an offer of about 1000 games, we are also satisfied. The majority of the games belong to the category of online slots.

An excellent casino has hundreds of slots on offer and preferably the latest slots as well. A top casino offers not only the best online casino games, but also exclusive online slot games. For example, One Casino has some slots that you can only play at this legal provider.

Try out free games

At any good legal online casino, you can try various casino games for free. You do this by creating a casino account, finding the game you want to test and selecting the demo version. Note that by playing free games you cannot win real money.

Free slots are especially popular among casino players. Because there are so many slots games, it is sometimes difficult to know which one suits you. Playing the demos will give you an idea of the graphics, odds of winning, bonus features, winning symbols and more.

⚙️3. The most famous software providers

Casino software providers make sure we play the most fun games with the latest gadgets, but their offerings vary quite a bit. That is why the best online casinos work with multiple providers.

A top online casino works with at least 10 popular game developers such as Netent, Pragmatic Play or Stakelogic. Does an online casino work with more than 15 developers? Admirable!

So scroll through the list of providers before choosing a casino. You can do this easily at many casinos via the game filters. For live games, every United Kingdom online casino works with Evolution Gaming.

Some online casinos operate partially or completely on their own software. For example, Casino has developed its own live games (with social interaction with United Kingdom-speaking live dealers!) and Tombola works entirely on its own bingo software. Below are the most popular software providers in the United Kingdom.

 💳4. The best casino payment methods

Playing at an online casino with real money often provides the best gaming experience. But, paying should be quick and easy. Imagine you hit the jackpot and the casino doesn’t immediately pay out to your bank? That’s a stress you’d rather avoid. So it definitely pays to check what deposit and withdrawal methods an online casino has to offer.

In an online casino, paying with iDEAL should not be missing. It is the only payment method we consistently see at legal online casinos. In second place come credit cards such as Visa and MasterCard. You can find those almost everywhere these days as well.

Other casino payment methods Trustly, Klarna and PayPal are somewhat rarer. Alternative e-wallets like Skrill and Neteller are yet to be seen at any online casino. Hopefully that will change soon.

Online casino deposits

Check out the limits right away: how much you have to deposit as a minimum and how much you can withdraw as a maximum. A minimum deposit of £1 is acceptable, but no higher. A maximum withdrawal limit of £10,000 is still okay, but £5,000 is absurdly low.

⭐ Online casino💸  The Storting limit Average deposit time💶   Transaction costs💳 Top deposit method
Cosmobet£1 – £25.000DirectNoVisa/Mastercard/Maestro
 Seven casino£2 – £18.000DirectNoMaestro/Visa/Skrill
 Ninewin£2 – £15.000DirectNoMaestro/Visa/Neteller

Fast payouts

Finally, it is also best to pay attention to the payout speed. Online casinos with fast payouts are hugely popular among the United Kingdom public. And rightly so. If you win a big jackpot, you obviously don’t want to wait a week for your money to appear in your bank account.

⭐ Online casino💸  Withdrawal limits Average recording time💶   Transaction costs💳 Top recording method
Cosmobet£5 – £20.00024 hoursNoMaestro/Visa/Skrill
Seven casino£5 – £18.00036+ hoursNoBank transfer/Visa/Bitcoin
Ninewin£5 – £17.00048+ hoursNoVisa/Maestro

🔒5. Playing at a legal casino

Security is everything. Without security, a hacker gets to your data with ease. Without proper measures, gambling turns from a pleasure into a problem. Therefore, it is best to gamble only at a reliable online casino that you can trust 100%. But how do you know if an online casino is legal and secure?

First, reliable online casinos have a license from the United Kingdom Gaming Authority. If an online casino has that United Kingdom license, you can be sure it operates fairly and has an excellent Responsible Gaming policy. So stay away from illegal providers and only play at legal United Kingdom casinos.

Second, every legal casino also cooperates with the Central Register Exclusion of Gaming (CRUKS), where problem players register themselves.

To keep hackers out, casino sites must be SSL-encrypted. In addition, all information about payments and bonus terms must be easily accessible. Most online casinos allow players to set their own time and budget limits and exclude themselves for a period of time. Casinos with reliable games use a Random Number Generator.

  • Play only at licensed casinos
  • Research what rules apply according to Gambling Law
  • See if the Responsible Gaming Policy is strong
  • Do research on the reputation of the online casino
  • Check if there have been any studies done on fair gaming practices
  • Check if the casino is secured with SSL encryption
  • See how easy it is to find important information
  • Find out if you can set limits for yourself

📱6. Mobile casinos and apps

Most players gamble via mobile devices. Yet a lot of online casinos still focus on their desktop version, leaving the mobile casino behind with flaws and a smaller game selection. This, of course, is unacceptable.

Our favorite online casinos have the best mobile casinos or even their own mobile app. You will find exactly the same games as on desktop, only adapted to the small screen of your smartphone.

Can you find the different casino games easily? Do the pages load quickly? Is it easy to pay via your mobile? These are the questions you should be looking for answers to. Designing a good mobile casino takes time and effort, two things you clearly want to see reflected when gambling via your mobile.

The best mobile casinos, or casino apps, are usually found at the newest online casinos. They design their gambling platform with a mobile-first approach: the mobile casino comes first, the desktop version second.

☎️ 7. Contact via customer service

It depends on what you like best: calling, emailing or chatting. For customer service to be complete, it must be accessible by e-mail and phone, as well as have a live chat with real employees (and not a chat robot). A frequently asked questions page is also helpful.

To know which number to call, though, you have to find the contact page first. Do you have to scroll all the way down the footer or click through five times to find an e-mail address? Then wonder if the casino might be intentionally hiding that information.

At the best casinos, customer service is available 24/7. If you’re worried about a payment, you don’t want to spend days stressing about it. The best casinos answer within a minute, three minutes at most. Of course, this depends on the contact method you choose.

Moreover, it is important that the content of the answer is good. A to-the-point, useful answer that really helps you.

In the table we compare the response times of different contact methods. So you know approximately when you can expect an answer to your question.

💻Email or contact formFrequentWithin 24 hours
💬Live chatFrequent1-3 minutes
📱WhatsAppRare5 minutes
📃Social MediaRareWithin 24 hours

 🎛️8. User-friendly website

The first impression is the most important one. Therefore, creating an account at an online casino should not be a difficult job. United Kingdom online casinos are required by law to verify your identity. At many casinos this only takes a few seconds or minutes, but sometimes you have to wait longer. Again, the faster, the better.

Another part of that oh-so-important first impression, is claiming your welcome bonus. You want to add it to your account quickly and easily, without having to go through dozens of steps and read a book of bonus terms and conditions. A clear and accessible welcome bonus is a big plus for new players.

Finally, the layout of the website also makes an important impression. How uncluttered is the online casino? Does the search function work well and do you easily filter by game type, software provider, theme or payout? Without these features, the website might not be so easy to use. Obviously, you’re not going to spend half an hour scrolling through all the slots to find the game you’re looking for.

The most popular types of online casinos in the United Kingdom

Online casinos in the United Kingdom come in all shapes and sizes. Below we highlight four interesting categories. For each of these categories we created a separate page, each with an overview of the best casinos in that category.

Do you like to play live or on mobile? Or are you looking for a completely new casino or a casino where real money can be won? Make your choice below.

💶1. The best real money casinos

  • Real winnings
  • Online casino bonuses
  • No transaction fees

 🤵2. Best live online casinos

With the advent of live casinos with real dealers, land-based casinos and online casinos have merged. This offers great opportunities, especially for players looking for that authentic casino vibe.

 🆕3. Best new online casinos

Playing at an online casino: your #1 guide

Are you registering at an online casino for the first time? Then this is the guide for you. Below we discuss in six easy steps how to get started.

Step 1.

Choose your favorite online casino

Choose your favorite online casino based on reviews, recommendations from friends or comparative websites like ours. Do you like to play live casino games? Then you have little use for an online casino that only plays online slots. Use the criteria above to find your perfect match.

Step 2.

Create a casino account

At a good online casino, it takes no time at all. You fill in your details, verify your identity and you’re done. Our tip: keep your identity card handy. You will always need it. During the registration process you also set your own limits. Be strict with yourself and think carefully about how much money you can afford to lose.

Step 3

Make your first deposit

Perhaps the most exciting step in the process. When you first play for real money, you prefer to pay via your favorite payment method. So check ahead of time if you can. After you make a deposit, it almost always appears on your account balance immediately.

Step 4

Claim your welcome bonus

Claiming a welcome bonus is usually done during your first deposit. Please read the bonus terms carefully before you deposit. This way you know how much money you need to deposit to qualify for the bonus and what steps you need to take to avoid missing out on those 50 free spins.

Step 5

Choose your first casino game

Choose your game carefully. After all, each game has different bet limits, odds and payout percentages. Not sure what games you like? Then try the free demos first. Also make sure you know the game rules well. If you dive blindly into the many casino games, you will lose money.

Step 6 Record any winnings

Although you gamble primarily for fun, winnings are always a nice bonus. Was luck on your side and did you collect a nice amount of money? Then it’s time to withdraw your winnings. At many online casinos you only withdraw money via bank transfer, which means you have to wait several days for it.

Benefits of playing at the online casino

What’s life without a little excitement? As long as you play responsibly, an online casino is fun, relaxing and an ideal source of entertainment. In fact, most players consider online casinos better than land-based casinos, and we couldn’t agree more.

Below we list the six biggest benefits of playing at an online casino.

Help with responsible gaming

Afraid of losing too much money or playing too long? An online casino that operates legally always has resources to help you with this. From time and loss limits to cool-down periods so you don’t play for a while. If you set your limits in advance, you won’t have to think about it afterward.

Lots of promotions and bonuses

One of the great advantages of a casino online is that there is almost always a promotion. Just a click or a quick scan will save you money on a game that you would have played even without the promotion. Especially if you want to get out of your comfort zone, many casinos accommodate you with great promotions on new games.

Huge amount of games

A land-based casino with more than 1,000 slot machines? Dream on. At online casinos, however, this is the most normal thing in the world. Not to mention table games in different variants. At online casinos, you keep discovering. Infinite gaming fun, with no queue.

Try out free games

At almost every online casino in the United Kingdom you can play free demo versions of most online slots games. All you have to do for this is create an account. That’s it. This way you test for free how to play a particular slot machine, what bonus features there are and how often you get winning combinations.

Help is always nearby

Even if you play from home, you are never alone. The best online casinos boast excellent United Kingdom-speaking customer service that is ready to help you day and night. All you have to do is click the live chat, grab your phone or open your mailbox.

It couldn’t be easier

Why make it difficult when it can be easy? Playing at an online casino can be done anytime, anywhere. Your favorite online casino games are at your fingertips 24/7 to add color to those dull moments in life; on your lunch break, on the bus or in the dentist’s waiting room. Nice and easy.
