How we review online casino sites?

Our gambling experts take reviewing casinos very seriously and we have developed a system to offer you all the important information. We create real accounts and play with real money to make sure everything works as it should. After checking the platform and going through its Terms and Conditions, offers, games, and every feature, we also listen to what other players have to say about it.

To put it bluntly, our rating & the system behind it.

So that you can learn how to compare our ultimate database of casino sites best.

How can we be of your assistance?

Our experts know precisely what you, as a British player, are looking for and are very aware of the fact that engaging in a session should be done only when one can trust that specific website.

In addition to this, we also consider the particularities it has and the features it provides.

Hence, our rating system is generated from an objective analysis of that specific platform. The online casino list presented below has been carefully created by selecting sites that are up-to-date with the technology's latest improvements, what kind of user experience it transmits, how fast and secure are the payment methods, and most importantly, how transparent and reasonable are the platforms with the imposed terms and conditions.

To better grasp how we rate a gaming site and how you can put your trust in us, we offer elucidations about each aspect we investigate.

Keep on reading and discover every aspect we check when reviewing online casinos in the United Kingdom! See how we keep everything accurate, up to date, and transparent for you.

1.     Licensing & Security   

It goes without question that we categorise casino sites as the top only the ones regulated by UKGC and that work with other gambling authorities such as MGA, Sweden and so on.

Why?

Because licensed iGaming operators can guarantee:

• Your safety as a casino member;
• Access to transparent information;
• The safety of your funds;
• The right to raise a complaint.

Our in-depth guide regarding all the essentials about the UKGC explains in details your rights and how you are protected by this trustworthy authority. Check it out and see why it is important to go for platforms who are licensed and regulated by it!

How we ensure your safety at British online casinos for real money?

We know that it’s not polite, but let us answer this question with another one: Do you know what SSL is?

It stands for Secure Socket Layer, and it ensures a safe environment for all punters. This is a crucial component for any secure online casino operator because it establishes secure connections between the gaming website and you as a customer. To put it simply, it’s a secure protocol.

Now, to get to the good part. How can you recognise if your trusted online casino has a valid SSL certificate?

Easy!

First and foremost, check if the URL starts with http://-. This is the first indicator of an SSL certificate. Next, click on the padlock next to it.

Did you click it?

Good! Now you should be able to see that the certificate is valid.

2.     Payment Methods & Payout Speed

Let’s say you’ve become a member of a British online casino; you've played and generated funds from that session. You expect to receive those funds in your account as soon as possible, right?

Our experts test all the banking options a casino offers and walk you through the deposit and cashing out processes. Also, we shine light on any issues or delays that may appear and even come up with solutions to these. The payment methods variety and processing time play a big role in how a casino platform is ranked on our website, so we pay close attention to these.

We know that payment methods are utterly important when you decide to play at UK casinos online. Fortunately, we’re here to tell you that this country's gambling industry offers the very best and most reliable ones to choose from.

3.     Game Catalogue & Software Providers

The game collection is vital to any user type, be it a new one or an experienced one at a specific platform.

The reason is quite simple: the collection of titles can be combined with that UK casino incentives and improve one's balance account.

This is precisely why our experts verify what type of titles there are and the software providers that platform has partnered with.

4.     The Available Bonus codes

When it comes to this aspect, it’s simple: You must have at disposal a broad spectrum.

So, our team of experts is instructed to verify how many types of promotions British online casinos have in their catalogue and how valuable they are.

To ensure that you will indeed receive what has been promised, we take every step you will take as a player from the United Kingdom.

Are you wondering how far we go for you?

We want to experience the casino just as you, as a player would, so we can deliver accurate information and create proper guides for you. Therefore, we go through all the steps that you will:  Register → Verify the account → Fund the account → Claim the incentive → Play with it → Withdraw.

Because we go to such lengths, we can state the reality, the whole reality and nothing but the reality without being influenced.

5.     Clear General Terms

It might come as a surprise, but it’s a vital aspect.

To understand better why we look thoroughly at a site’s terms and why these must be transparent, suppose the following.

You’ve reached an iGaming operator. Even though these are perceived as a binding contract, you haven't read the terms and started depositing and playing.

After you’ve ended your session, when you try to request a withdrawal, some issues arise. You will wonder what is the reason and try to find the answer through customer support. They might or might not be helpful, and finally, the entire situation will gradually become frustrating.

When you reach such a situation, it might be because you skipped a little clause in the terms and conditions. Now, that is why we carefully analyse these terms.

We are aware that when you want to play casino games, the last thing you have time for is read the Terms and Conditions. This may be dangerous as you may agree to certain terms you deem unfair and will only notice when you encounter an issue such as being unable to cashout or, even worse, having your account blocked.

That is why we take the time and go through them, highlight the most important aspects that may positively or negatively impact your gaming sessions. Even more, we do our best to put it all in simple words and explain all complicated aspects so that even inexperienced players will know what they are getting into.

6.     Same Features on Different Devices

We live in the golden age of mobile technology. Hence, we must thoroughly investigate if platforms ensure the same smooth session on both desktop and mobile devices.

We know that most of you prefer to access the best online casino sites in the UK via mobile. Thus, we test it to guarantee that there is no difference between the devices.

7.     Reliable Customer Service

There might be certain times when you will need additional support from the customer support team. Hence, to ensure that the problems one might encounter can be solved quickly and smoothly, a platform must provide various contact methods.

These are:

• Email address;
• Live Chat;
• Phone number.

The majority of top online casinos in the UK come with all three options and usually provide 24/7 support. Besides this aspect, a gaming operator must also have a good support team behind which will offer accurate answers to all your issues.

Here is where our experts intervene.

Our evaluation system of the customer support

To ensure that you will have everything at your disposal, including a good support team, we verify each option.

Now, one may wonder at what aspects our specialists look at and how it can influence our rating system.

Let's take a look below:

1. Response time: the time it takes for the support staff to reply to our queries via the different communication ways they offer is very important. This is of even more importance when the platform has a Live Chat option, which should be one of the fastest ways you can get in touch with the customer care team.

Even though some platforms say they offer 24/7 support, their response time might be longer.

2. Accurate information: Understanding what the member wants, resolve the query and professionally close the interaction is a must for a top online casino in the UK.

8.     Look & feel 

We shall break this section into three categories.

First, we shall talk about the site's performance, if there are any lags with it and how we rate it.

Secondly, we shall point out how the registration process is supposed to look.

Last but not least, we shall offer elucidations about the mobile interface.

Interface: User experience

To deliver the most accurate information regarding the user experience on a site and to be able to analyse and rate a casino site, our experts use various tools and means.

We value our customers and our main goal is help them all have the best gaming experience in a safe and responsible manner. Therefore, we go to great lengths to offer objective information about each casino and their offers.

How we do it?

Our team opens an account on the platform that will be analysed, funds it and verifies it thoroughly.

These are the three main steps. However, besides these, they also use the GTmetrix tool to check the performance of the site.

Basically, when we list a site as the best online casino, we consider what we see or encounter on that particular platform and use additional tools to see what is behind it.

For a better understanding, let's take into consideration the below ranking.

3 top-rated online casinos in the United Kingdom

Even though PocketWin does not have the same performance score as Betfair, we have given it 4.5 stars out of five and placed it in the primary place because it exceeded our expectations.

Besides the excellent user experience, we've also given it extra points for originality because it has in-house games, reasonable requirements and the secure payment method Pay by Phone.

  Even though we've emphasised the above reasons for putting PocketWin at the top, that doesn't mean that Betfair and Dr Slot lack those things. We want to point out to our audience that when we categorise a website as a top online casino, we consider various aspects.

A simple guide on how to register

The registration process is an important aspect we take into consideration when rating and reviewing an online casino. When we look at it through the eyes of a beginner player and conclude if someone with no casino experience would be able to complete it without any issues.

Why?

To emphasise how it’s supposed to look so that you can know the difference between a standard site and a premium casino website in the UK.

So, here’s what you should expect when opening an account in terms of interface.

1. First, scroll down and choose your favourite from the online casinos in the UK.
2. From our page, navigate to the website you've just picked.
3. Now check the platform for a Register or Join button and tap it.
4. See the panel that just popped into existence? Pick a username and password and then press forward.
5. Complete the forms with your full name, email, address, and phone number.
6. Prove that you're a real person by providing a valid ID card.
7. Choose a payment method. Most platforms allow deposits via e-wallets (Skrill Moneybookers, Neteller, MuchBetter, ecoPayz, PayPal, Paysafecard, Ukash, Instadebit etc.), prepaid cards (Paysafecard, Todito, Astro Pay Card), online bank transfer (iDebit, INTERAC, Trustly, EPS, Nordea, Sofort). Cryptocurrency can also be an option on some websites. Read the terms and conditions to make sure the site supports the method you usually use.

Presenting the British iGaming Market

The online gambling industry is evolving day by day, which means that more gaming sites are launched, more features are added, and the technology behind them is constantly upgraded as well. Therefore, our best gambling sites page is constantly changing as well as we add more brands and adjust the rankings accordingly.

We want to deliver accurate information about this market and state the reality, and nothing more.

According to the above statistic, since December 2017, the number of players has increased by up to 2% on desktop and up to 5% on mobile. From this, we can conclude that the more players start joining this community, the need for new casino features becomes crucial.

Even though our experts have already analysed to create a casino review, they shall continually verify if that specific platform is up to date with the new technologies that are being developed.

A good example is the VR technology which allowed online casinos to offer Virtual Reality games. This took the entire industry to an entirely new level, as such online gaming sites are not too many and it is a very interesting feature to offer. It gives British players the chance to be fully immersed in an almost real experience right in their own living room.

An example of such technology is the VR features which can be found in online casinos. Virtual reality's power is gradually becoming part of this industry, and platforms with 2D or 3D will soon cease to be considered a top.

Are English online casinos safe?

Yes! There is no doubt regarding this aspect. All the best online gambling sites in the UK work under the licence granted by UKGC.

Key strength points of a secure online casino

Let's see what the main benefits of a license issued by Britain's main regulatory body, the United Kingdom Gambling Commission (UKGC), are:

• The agency makes sure that all types of gambling activities, online or land-based, are conducted in a fair, open way. At the same time, children and other vulnerable persons are kept away from it. That's why you'll have to be 18 years or older to gamble on any of the websites listed on our platform;
• UKGC-regulated gaming platforms need to follow the requirements set in their Licence Conditions and Codes of Practice document. This means the platform must take into account rules regarding technical standards, protection of customer funds and personal information. Also, it must include regulations about payments and anti-money laundering laws. The commission has powers to take action against licensed operators who fail to comply with the rules, visit their website to learn more about this;
• All UK casinos have to promote social responsibility and awareness about the risks of the iGaming industry. That's why the best online casino you can stumble upon is the one that features a Responsible Gaming menu, where you'll discover, step by step, how to have the safest journey possible. For instance, some platforms out there will give you the option to contact the customer support crew and ask them to attach a so-called Reality Check message to your account. This will automatically put limits on how long you're allowed to play games. You can also take a self-assessment test by completing a UKGC-approved questionnaire to check if gambling is becoming an issue for you.

Why is a casino license essential?

There's no room for modesty: the British gambling market is among the safest and most regulated in the entire industry.

The UKGC is a very strict and trustworthy authority which oversees gambling activities of their licensees. That is why we strongly recommend you to go for platforms regulated and licensed by this authority. They provide the highest level of safety. This is not the only authority you can trust, but it is the one that focuses the most on the player’s experience.

Recommended casinos with UK license

You might think that the aspects we’ve mentioned in the table are unnecessary, but we beg to differ.

Let’s take a quick look at the hidden significance of the legal name, the licence’s year and so on.

An online casino's legal name

The legal name of English casino sites stands for the company that operates that specific website.

You may not be particularly interested in this, but it is a good information to have. With it, we can access other details and statistics about the company, as well as check if they had any legal issues recently. We also use it to check if they are listed on the London Stock Exchange or have been penalised by a licensing authority.

The significance of the legal name

Why should you know it?

Knowing such things could answer the questions of all type of players.

For instance, a company listed on the London Stock Exchange can ensure that that specific company will guarantee protection when it comes to members funds. The same applies when we point out the share price.

Through this, you can be informed if that specific business meets the industry's expectation.

How could it influence your user experience or gaming session?

Is it safe or not to fund your casino account?

If, after making thorough investigations, our experts discover that UKGC has fined a company for reasons such as not complying with the laws regarding self-exclusion, withdrawing processes and so on, you could draw a conclusion about that platform.

Meaning, you can decide if it is worth to open an account and make a payment.

Year of obtaining the license and the nr. it has

Emphasising a site's year it has been granted with a gambling licence and the number of licences it can have underlines the fact that it has experience in the gambling industry. It also implies that the site knows how to comply with the laws and regulations indicated by the authorities.

In addition to this, it guarantees that the platform is safe due to the fact that it must go through various checks and verifications to obtain such licenses.

Are online casinos rigged?

Online casinos are not rigged as long as we talk about the ones who have a license issued by anu authority, especially one from the UKGC. We only present you with fully regulated and licensed gambling sites, so there is no need to worry about that.

However, you have to keep in mind that you can find unlicensed gaming sites on the Internet and we have no certainty that their games and practices are fair. That is why we advise you to avoid such platforms and pick one from our curated list.

 There are online casinos that do not work under a gambling license. Always check the footer of the sites for the license logo.

Nevertheless, this question is still being asked by players, being they new or experience in the iGaming industry.

While investigating this issue, our specialists have come to the conclusion that this question is still being asked due to the fact that players think that the titles are set up in a way so that they can never generate winnings from a session.

However, this is due to the fact that the online casino must have an advantage that favours the house because otherwise, it could not be able to continue to operate.

This factor is most of the times confused with the occurrence of rigged games. You must consider that all best casino sites licensed and regulated by a gambling authority use the Random Generator tool.

What is a Random Number Generator?

As the name suggests, it is a tool that generates unpredictable numbers. Hence, even though it might appear that a session might not seem random, it is not necessarily an indication that it is rigged.

Is problem gambling a real problem?

Problem gambling is an issue that affects more and more British players, some even underage. While the UKGC and the British authorities are putting in great effort to keep this under control, this is a real problem that we have to be aware of.

Our team of professionals put together a guide where they teach you the signs of gambling addiction and how to attain a healthy gambling perspective.

We believe it's essential to know beforehand the signs of problem gambling. This way, you will learn how to prevent addiction.

How to solve a dispute?

Our purpose is to build a relationship based on trust with you. Hence, we’re always at your disposal with additional support when you need us the most.

However, we must emphasise the fact that we cannot solve issues relating to casino sites. Still, we come to your aid with redirections to professional organisations that have the necessary means to help you solve disputes.

What makes a casino site a top online casino?

We’ve searched, analysed and came with an answer. Now it’s time to help you understand the true meaning behind a top-rated online casino site in the United Kingdom.

But first, let us explain to you what top stands for us.

The essence of TOP in Online Casinos 

As everyone knows, the top is defined as the highest point of something or the most elevated position, which is understandable. However, when we have thought about what it means for us, such a casino, we had to take things a little bit further.

From our perspective, a top online casino does not have to be a platform in the highest position in this gambling industry.

When our experts have compiled this page, first and foremost, they had to think about what truly stands when we categorise casino sites as top casino sites. Before we begin explaining our methodology behind this page, let's take a closer look at the meaning of TOP.

T: Is for the trustiness of an online casino and how reliable it can be.

O: Stands for the originality of an online casino what new features it can provide.

P: Is for how perceivable are the terms and conditions

Note: Our review system contains our specialists' analysis of various aspects of a site which include but are not limited to the interface, game catalogue, partnerships with software providers, how can a casino be trusted, what type of payment methods it accepts and many more.

We shall offer you elucidations regarding what we take into consideration when we say that a website is one of the best casino sites in the UK. To better understand our system, we shall explain each criterion through tables, examples, and schemes.

Quality casinos

What truly means a quality casino?

Well:

Our P from TOP stand from perceivable.

It is utterly important for a casino’s Terms to be easy to understand by its customers regardless of their previous experience with gambling. There are cases in which casinos use the same Terms and Conditions for their brands on other markets so they end up not being applicable to the British gambling market. This means that the currency may be different, the amounts, and even some rules may not apply or even be missing.

These cases are rare, but you can come across one if you look for a casino on your own. That is why we come to your aid and only give you top-notch options which have been thoroughly verified by us.

While creating this top casino list and verifying each gambling operator, we've discovered that some sites stand out more than others.

The top three mentioned platforms have proven to transmit their terms and conditions in the most logical and accessible way. We haven't found any misleading or unreasonable requirements that can affect the users' experience.

Now, we might let you wonder:

What makes an online casino in the UK indeed be the best online casino?

Well, it must offer punters a broad spectrum of features.

Let’s dive right in!

Wide array of bonus codes

Some of the best casino sites usually come with a comprehensive collection of promotions which can vary from welcome offers to bonus rounds without deposit, daily, weekly and monthly promotions.

Thus, when we rate a platform, we consider how many offers it provides and how reasonable the bonus policy is.

The gambling industry is continually evolving, and platforms are being launched daily. Hence, the competition is pretty stiff. For a site to be considered the best online casino in the UK, it must also come with additionals besides the bonus codes collection, such as the VIP programme.

VIP programme

While compiling this page, our team has discovered that the loyalty programme can come in three different shapes:

• The game-like program is one of the most fun ones to join. It comes with a special theme that often matches the overall theme of the casino. The levels are created as separate worlds each with their own challenges and perks. It may even come with its own mascot that is going to keep you company along the way or give you tips;
• The multi-level VIP club – this is a typical VIP club that comes with 3 to 6 levels. From Bronze, Apprentice, New Member, Expert or Diamond, you can encounter different names to describe your level of experience. You get significant benefits as you level up;
• The basic Comp Point system – the simplest of them all, the Comp Point system does not come with levels. All you have to do is play games, and each bet you make brings you several Comp Points. Exchange these in the casino store for bonuses, perks, and even gifts such as smartphones, video cameras, and more.

No matter the type of programme it has, it should have such a feature.

Fast and secure transactions

Which are the recommended payment methods in the UK?

The most sought out methods in this niche are Bitcoin, PayPal, Pay by Phone and Boku.

Strictly regulated by the UKGC, these platforms cannot afford any mistakes. Furthermore, we consider these sites like the best online casinos because these banking options are the safest and fastest methods accessible to any British player. In addition to this, the methods mentioned above allow payments to be made in an almost anonymous way.

For the full list of which online casino accepts PayPal or any of the mentioned banking options, we invite our audience to check the dedicated pages for each one.

What payment alternatives are most common in the UK?

There are E-wallets available such as Paysafecard, Entropay, UKash, EcoPayz, and so on.

Their popularity comes from the high level of security they offer, as you do not have to type in your credit or debit card information. They act as a middle man between you and the casino, so you do not have to share sensitive information via the Internet if you are not comfortable doing so. In addition, transactions are instant, so your deposit will be ready for you to use in the blink of an eye. The same goes for cashouts, but the timeframe may vary depending on how long it takes the casino to verify and accept your withdrawal request.

Keep in mind that even some of the best UK casinos require a few hours to a few days to run verifications on any payment request.

However, in the case of Bank Transfers, it can take from 1 to 5 days for deposits to be processed. As for withdrawals, there's a time frame that goes from 1 and 10 days.

These actions can be performed either from your own bank's app or by using Euteller, Sofort, POLi, Trustly, Zimpler, Entercash, TrustPay, Citadel, InstaDebit, and more.

Games & providers

What is the best software for online casinos?

We know the most sought out providers precisely due to our thorough-made investigations, and we’re ready to present them to you.

Top game providers

Check our dedicated pages for an extensive list of bonuses that can be combined with the mentioned providers.

What makes an online casino original?

From our point of view, it stands from games that cannot be found on other casino sites.

Lets' take as an example the below table.

All of these websites are ranked as the best online casinos in the UK. Besides the fact they offer a wide array of titles, these platforms have also partnered with many software providers, which also include the most ought ones we have mentioned above.

Now, you may ask yourself: Why has been Cashmo listed in this top casino sites?

You will see that it has a small collection of titles and only one provider at first sight. However, we have categorised it as the best platform due to the fact that its games are in-house made. This adds originality to the website, as they have their own team that develops unique games you cannot find on any other platform. This is a great advantage for some players who wish to try different titles in their gaming sessions.

Mobile accessibility

The most asked question is: Mobile app or mobile interface?

The very best UK casinos in 2021 come with both a desktop version of their website and a mobile one, accessible from any device and via any browser.

Two technologies help you use your browser to play your favourite games - Flash and HTML5. Here are their main differences:

When it comes to the device requirements, note that these gaming platforms all work on any smartphone or tablet, no matter what operating system it runs.

So, whether your device runs Android, iOS, and even Windows, you will still be able to play if you have a stable Internet connection.

Some even developed dedicated apps players can download and install for even quicker access. These apps can often be found right on the casino's website and also on the App Store or Google Play Store.

Keep in mind that sometimes, the app may not be available on every operating system. If, for example, the app is for iOS devices only and your device runs Android, you will be able to still enjoy the fun on the browser version from your smartphone or tablet.

How to choose the best online casino

We’ve proved how trustworthy we can be. That’s right! Now we’ll teach how to best use our knowledge for your benefit. We, at KingCasinoBonus, make it is easy to compare online casino sites in the UK.

1. Select an English casino site from our compiled list of regulated platforms.
