The Real Meaning Of The “UK Casino”

Contrary to popular belief, from the best online casino websites not all the ones that accept members from the United Kingdom are called “UK online casinos”. This title can be used by the websites that are licensed by the United Kingdom Gambling Commission (UKGC).

This licensing agency is the most respected one in the world and it is quite hard to get a license from it. You need to have a perfectly clean background, a couple of hundreds of thousands of sterling, and a company located in Britain.

Only then, you can apply to UKGC for a casino UK license. And there is no guarantee about whether you can get it: Only the best gambling operators with a perfect background can get a British online casino license.

And this is why the 100 best online casinos – UK based are some of the most reputable gambling websites in the world: If a website has a UKGC license, it is as good and trustworthy as a bank.

So, how can you understand whether a casino website is licensed from UKGC or not? Checking the games, payment methods or bonuses is not the answer – you must look for the logo of the agency.

Basically, it is a logo that says “Gambling Commission” and when you click on it, the official UKGC website launches for verification purposes. All UK casinos online put this logo to the bottom of their main pages, so check that section first and don’t forget to click on it to verify.

If all goes well, you can start enjoying casino games and the newest online casino promotions, such as online casino UK free bonus no deposit, because all of them will be safe and fair. Basically, make sure that you are really playing at an online casino UK by checking & verifying the license.

And if you are wondering how did we pick the best UK casinos online and best online casino bonuses UK, keep reading: We will explain our process in detail below.

How Do We Pick UK Online Casinos?

So, what is our “secret” of finding the best and most trusted online casinos UK with the best bonuses and games? Well, we use a long list of criteria, to start with.

We are professionals and have a combined experience of more than a decade in the iGaming industry, so we know where to look and what to look for. We can find you UK casino sites that have a rank score 100 – 100, because:

We check their games and how fair they are. This is the first thing we check for while preparing a UK online casino review: The quality and quantity of the game collection. We make sure that you can play all kinds of game types, table games, baccarat (here you can learn how many betting positions are there on a baccarat table), poker, blackjack online games and, of course, slot machines. And we check the quality of their providers – the numbers alone are not enough to impress us. Lastly, we check the RTP rates of all UK casino games online and make sure that they are fair.
We check the security and legality. Needless to say, all of our UK online casinos are licensed by the United Kingdom Gambling Commission. Moreover, they are safe & secure websites, protecting all of their pages with SSL encryption. This means all of the confidential information (such as your credit card data) between your PC and the server stays secure. We also check the integrity of the website and make sure it is not compromised.
We check their bonus offers. A 100 first deposit offer will match your bankroll 100%, but are you sure that this is a fair bonus? Have you checked the wagering rate and read the terms & conditions? Well, we did check them all. Whether it is a 100 welcome bonus or an online casino UK no deposit bonus, we tested each and every promotion on casino UK websites and made sure they really give you an advantage.
We check the deposit methods. And of course, we checked the quality and quantity of the best casino payment methods too. MasterCardNeteller, VISA, PayPal (highly recommended at NetEnt casino PayPal sites) – no matter which one is your pick, you can use it at one of our recommended online casino UK websites. More importantly, no matter what your budget is, there will be a payment method to use, even for 1 GBP deposits. And of course, if you are a high-roller, we make sure you get the best deals and zero fees.

We check customer support too. The quality and speed of customer support are important: All of your complaints must be resolved in 24-hours maximum. Moreover, customer representatives must be helpful and professional. We create “doomsday” scenarios to test their response time and helpfulness.

Basically, our UK casinos list contains your best and most trusted options for online gambling from the United Kingdom. If an online casino UK fails to impress us, we don’t recommend it – simple.

There is no need to waste time to search for UK casino online sites on the internet: Leave this job to professionals like us and start playing directly. Do you want more information about each criterion on this list? Here you go.

Which Casinos Make It To The Top Online Casino UK List?

The UK is one of the strictest gambling atmospheres in the world. Why? One of the most credible gambling bodies resides here and so any platform that operates in this environment has to meet certain terms and requirements that have been put in place by the United Kingdom Gambling Commission.

If you are not comfortable playing in other casinos, you can choose any of the safe online casino UK sites that have been licensed by the authority.

Why Play At UK Casinos?

The safety and the security of the customer is of utmost importance when it comes to gambling. We agree that gambling is a form of entertainment that has quickly drawn millions all over the world, but we should not be quick to ignore the safety of the player.

Gambling, real money gambling in this case uses delicate information as well as banking information which is obtained from its players at the point of registration.

As cash is involved, scammers have an found an easy way to creep into internet casino UK sites and create rogue websites and swindle customers of their money.

Any player looking to play with any safe online casino UK should ensure that the site is registered and has an operations license from the Gambling commission. This is one guarantee of the safety and the security of the information you provide the site with. Banking and personal information may not only deplete your bank balances but the information may be used for fraudulent reasons.

Top UK casino websites have the badge or a licensing certificate that is clearly indicated on the casino’s website or its homepage. If you are not confident of this, you can visit the Commission’s website and verify its legitimacy and if the license is actually genuine.

Top UK online casino sites have more than just a license to show. The slots and games offered in the sites are some of the best in the world. They employ the services of the best online casino software providers such as Microgaming (here you can find our Microgaming casinos full list) and NetEnt (also check our NetEnt casino list UK specific). This guarantees you the ultimate gaming experience due to high quality sound and graphics that are incorporated in each game.

Playing with UK best online casino sites is probably one of the best decisions that as player will ever make. Payments are made promptly, there is reliable customer service and your information is held with utmost care by the casino you are paying with.

In case of any issues that are not satisfactorily addressed by the site, you can raise them up with the Gambling Commission.

Find The Best Online Casino Bonus In The UK

Go ahead and make a search for “online slots no deposit bonus UK”. There will be thousands of results, literally. Each of these results will claim to be the best one and give you the maximum number of free spins.

Thing is, you don’t have enough time to check and verify all of these claims: You must use your time for playing UK casino games, not for surfing aimlessly.

Well, we have all the time in the world and this is our job, after all: We check all of the free spins casino UK bonuses (and other casino UK promotions) for you.

While checking the promotions, we start with finding the types of casino bonuses (first deposit, cashback, online casino reload bonus etc.) first. Then, we check the expiration date, minimum deposit amount (like at the $5 minimum deposit slots sites), and bonus codes (see our Campeonbet Casino bonus code guide), if there are any.

Lastly, we carefully read the terms and conditions to see the wagering rate, time limit, additional account restrictions until the requirement is over, and which stakes contribute towards wagering & which do not. We are always searching for online casino low playthrough requirements.

Checking a casino online UK no deposit bonus, for example, requires much more than becoming a member and starting to use free spins.

We look for how fair that bonus is – yes, a marketing line such as “online casino no deposit required UK” may sound good, but how real is that offer? Does it really give you an edge or is it just an empty promise?

Before clicking the “play now full terms” button, we make sure that that bonus is worth taking.

Play The Best UK Online Casino Games

Testing the game collection and finding the online casino games in best UK takes more time, as can be expected. We check for the pure numbers first and see how many games you get to play.

As a general rule, our recommended online casino UK websites offer at least 600+ games in different categories. Second, we check the quality and find out whether those games are worth playing or not.

To do this, we find out the providers: There are dozens of game developers in the iGaming industry but only a couple of them are truly successful.

We make sure that you get the chance to play the latest and most popular games of top-tier providers, such as Microgaming, Netent, Big Time Gaming, IGT, and Betsoft. If you choose a casino from our Netent casino list you can even get a Netent casino bonus.

And we do not check only “regular” games: We know how important live dealer online casinos are, so we test them separately – there should be no lag or visual problems, no matter your location in the United Kingdom.

That’s not all: We try the games on different platforms and make sure that they work flawlessly on mobile or desktop. No matter what kind of device you are using, you can play the entire game collection of our recommended online casinos in the UK.

Moreover, you can reach customer support, use deposit methods (bank transfer, credit card, e-wallet, etc.), and access all other features from mobile devices too. You can check out here our mobile casino list.

Make Your UK Casino Online Payments Easily

Playing casino games at online casinos UK is fun, but you will also want to withdraw your winnings too, sooner or later. Moreover, you must make a deposit first, in order to score a winning.

Well, we check both and make sure that all deposits & withdrawals work without a problem. In this regard:

  • We check the number of available payment methods – the more the merrier. Legit online casino PayPal sites, for example, are quite popular in UK, as PayPal is a very secure payment method and has ‘buyer protection’ policy. But that’s not all: Our recommended casinos accept several other options too, such as credit cards, bank transfers, and even cryptocurrencies (like Bitcoin casino UK sites).
  • We check the minimum & maximum transfer limits of all deposits and withdrawals (even at minimum deposit casinos or £3 minimum deposit casino – UK based). If you are not allowed to withdraw more than 2.000 GBP in a week, for example, maybe you shouldn’t waste any time by trying to score a jackpot prize – winning millions of pounds does not make sense if you cannot withdraw it at once.  However, it is the opposite when it comes to deposits: We make sure that the minimum limits are as low as possible, so all players can get a chance at playing UK online casinos, no matter what their budget is. When depositing with Siru at Siru Mobile casino sites, for example, there is a minimum deposit limit of £5 at most casinos.
  • And of course, we check the speed of withdrawals. We know that each UK casino has a different time frame when it comes to withdrawals, but we expect all cashouts complete in 24 hours, no matter which payment method you pick, but in UK you can find a lot of them, such as Cashlib or ClickandBuy. If you want to be sure that you get your money as fast as possible have a look at our fastest withdrawal online casino UK list or at the instant withdrawal casino sites.
