How We Rate Online Casinos
So what makes us qualified to be able to rate and recommend the best online casinos? Well, we have a team of experts with years of experience in the field who know exactly what players want from their online casinos. Our experts closely examine each of these criteria to ensure that all of our recommended casinos are up to our high standards. Letās take a closer look at what we look for.
-
Licensing
Every online casino we recommend is fully licenced and regulated by a recognised gambling authority. Having a licence to operate in the UK is essential, as it proves that the casino can meet the player safety and security standards of the UK Gambling Commission. The UKGC is one of the most respected gambling authorities in the world and was set up in 2005 to help regulate gambling companies within the UK.
A licence from the UKGC shows everyone that theyāre fully above board and operate a fair, secure site. Getting one of these licences isnāt just a one-time thing. Online casinos must continue to prove that they meet these high standards to keep their licence.
-
Bonuses and Promotions
One of the major benefits of playing at an online casino is all the bonuses and promotions they offer. Many sites offer generous welcome bonuses to new players, and the top online casinos in the UK even offer ongoing promotions to keep their existing customers happy. Our experts compare the bonuses and promotions on offer across various sites to ensure youāre getting the most value possible.
-
Design and Usability
An often overlooked aspect of an online casino is its design and user-friendliness. A good casino design is one that you donāt think about – it does its job without drawing attention to itself. Having a good design is essential to a good user experience. You want it to look good, while still being easy to navigate.
-
Deposit and Withdrawal Options
Another key feature of any online casino site is its banking options. If you canāt quickly and securely move your money on and off the site, you wonāt want to create an account! Thatās why we look at all aspects of online casino banking. This includes your payment options, minimum and maximum limits, withdrawal times, and fees. We feel itās important to have all of this information before choosing your online casino. Thereās nothing more troublesome than finding a good site only to find that they have high fees or long withdrawal times!
-
Software Providers
Many people understand why having a good selection of quality games to choose from is important, but just as important is the quality of the software providers. After all, weāre sure youāll agree that a site with a few hundred high-quality games is much better than one with thousands of repetitive, low-quality games. The software providers are the best indicator of a siteās game quality. The better the game providers, the better the games will be. Also, the more software providers you have to choose from, the better variety of games thereāll be to choose from.
-
Games Selection
Arguably the most important feature of any online casino is its game selection. A site needs to have hundreds of games available if it wants to compete in todayās market. They also need to meet the quality standards weāve come to expect over the past few years. Online casinos canāt get away with hosting twenty slight variations of the same game and calling it a day, but players demand variety. Our experts thoroughly examine not only the variety of games available but also the quality of those games to ensure that we only recommend the best of the best.
-
Payment Options
Being able to get paid out after a winning session in a quick and efficient manner is another thing thatās important to many UK players. Many sites do not offer the same level of withdrawal options compared to deposit options, making it easy to deposit money to the site but hard to get it off. Thatās why we have our team of experts not only look at the deposit options but also the payment options to ensure that you have plenty of ways to get your money off the site in a safe and secure manner.

Customer Support
After depositing and gambling with your hard-earned cash, you want to know that you wonāt be left hung out to dry if anything were to go wrong. Thatās why we check each siteās customer support team as part of our review. One of the most important things we look for is the teamās availability to ensure that youāll always get the help you need whenever you need it. We also check the responsiveness and helpfulness of each siteās customer support team, so you know exactly how much help youāll likely get if anything goes wrong.
How to Choose Best Online Casino

Now that you know how we rate online casinos, how do you find the one thatās right for you? It can be a tricky question, especially if youāre new to the world of online casinos. However, weād always recommend that you focus on the aspects of a casino that are most important to you, whether itās the gaming options, the bonuses, or the mobile gaming experience. Here are a few of the key things you should consider when trying to find the best online casino gambling site.
Great Bonuses
The bonuses and promotions are the most eye-catching aspect of online casinos, so itās no surprise that many people consider them when picking their site. However, itās important to find a bonus that offers value and is right for the games you want to play. For example, if you want just want to play table games, thereās no point in signing up for an online casino that only offers free spins. The best-rated online casino sites offer generous welcome packages that cater to players of all game types, so make sure you pick one thatās right for you.
A Large Game Variety
A key aspect of any online casino is the variety of games they offer. If you love playing online casino games, this may be the most important aspect to consider. Some sites only offer a couple of hundred games, whereas others offer well over a thousand. Letās take a look at some of the most common games youāll find at an online casino.

Easy Sign Up
When starting off your online casino journey, you donāt want to be inconvenienced by a lengthy sign up process. In fact, you want to jump right into the action! Many sites have made great strides in simplifying their sign up processes as they realise they could risk alienating players if they ask for too much too soon. However, some sites still require you to provide proof of ID and address before youāve even created your account! By checking the sign up process of your online casino before committing to it, you can save yourself from a long registration.
Common Payment Methods Accepted
Being able to easily deposit and withdraw from a casino is a dealbreaker for most people, as they donāt want the hassle of using unfamiliar payment methods. All good casino sites these days offer various payment options, with popular methods such as PayPal, Visa, and MasterCard accepted at most casinos. Itās important to find the sites that offer the payment methods you prefer to use, as it makes the process of depositing and withdrawing a much smoother experience.
Fast Withdrawals
After a big winning session, the last thing you want to do is wait days to receive your money. Online casino payments have taken a big step forward in the past few years, and many payment methods offer 24-hour withdrawal times. However, despite this, many sites still take multiple days to process each withdrawal request. Thatās why you should look for sites offering fast payment methods and processing times to ensure you get your money as soon as possible.
Mobile Experience
Gaming on the go has become increasingly popular over the past decade thanks to the advancement of smartphone technology. To take advantage of this, many sites offer mobile gaming options that allow you to experience their full range of games from your mobile. Some sites offer a dedicated mobile app, whereas some offer a mobile-optimised website, so make sure you pick the one that you find most appealing.
UK Casino Reputation
In the gambling world, reputation is everything. If a player has had a bad experience at a site, you best believe that youāll hear about it, and if theyāve had a bad experience, whoās to say that the same wonāt happen to you? Picking reliable online casinos with a good reputation in the UK gambling community means youāre more likely to have a good experience. All of the sites we recommend are highly reputable online casino sites within the UK gambling industry. This means that no matter what you pick from our list of online casino sites, you can be sure of a good experience.
Security and Customer Support
One of the reservations that many people have about online casinos is whether or not theyāre safe. While itās true that back in the 90s, online casinos were a bit of a Wild West, nowadays, the market is much more regulated. Each online casino that operates within the UK must hold a licence, and many of the best sites use a range of high-tech security features, such as firewall technology and encryption technology, just to name a few.
Licensing and Legislation
As we mentioned above, each online casino site operating in the UK must hold a licence from the UK Gambling Commission. The UKGC was established after the UK legalised gambling in 2005 with the passing of the Gambling Act to regulate the companies that operated in that space. Since then, the UK Gambling (Licensing and Advertising) Act passed in 2014, which requires gambling companies to hold a licence from the UKGC to legally offer games to UK players.
Types of Casino Bonus Offers
The best online casinos UK will offer you a range of different bonuses and promotions to tempt you into signing up. Some of these bonus offers are much better than others, so it pays to know which ones are worth signing up for and which ones donāt offer much value. If youāre looking to pick a site based on the bonuses they offer, itās important to know all of the types of bonuses youāll encounter. Letās take a closer look at the types of bonuses casinos will offer you.
Free Spins at Online Casinos
This one is self-explanatory – the casino offers free spins at some or all of its real money online slots. Some casinos require you to make a deposit to claim your free spins bonus, whereas some will give you free spins for signing up or verifying your account. When it comes to free spins, the bigger the number, the better, so if you want to get the most value possible, look for the sites offering the most spins.
Reload Bonuses
While many people focus on the eye-catching welcome offers, itās the promotions for existing players that will keep you playing long after your welcome bonus has been and gone. A reload bonus will reward you for making a deposit to an online casino after youāve made your first deposit. This reward can come in the form of free spins, bonus funds, or free bets, but the most common form of reload bonus youāll see is a matched deposit bonus.
Welcome Bonuses
All good online casinos will offer some sort of welcome bonus, even if some are more generous than others. A welcome bonus is a bonus an online casino will offer to players who have not made an account to try and persuade them to join their site. These bonuses are often the most generous offers a casino will give to its players and can come in many different forms. The most common form of welcome bonus youāll see is a matched deposit bonus, but many sites also offer free spins as part of the offer.
No Deposit Bonuses
By far the rarest and arguably the best online casino site offers youāll see find are no deposit bonuses. These bonuses reward you with free spins or bonus money without requiring you to make a deposit first. This essentially gives you money for nothing, which is why theyāre both so popular and so rare. The most common form of no deposit bonus youāll find is a free spins no deposit bonus, but some sites do offer bonus funds, so keep your eyes peeled for them!
Match Deposit Bonuses
A matched deposit bonus is one of the most common offers youāll find at an online casino. When you claim this bonus, a certain percentage of your deposit will be matched by the casino up to a certain amount. For example, if a casino has a 100% matched deposit bonus up to Ā£100, if you deposit Ā£100 of your own money, the casino will give you an additional Ā£100 in bonus funds.
How to Register at Online Casino Sites
Once youāve found a site with an appealing enough bonus offer, itās time to create an account! Luckily, many popular online casinos in the UK market have simple sign up processes, so you can create your account and start playing in just a couple of minutes. Youāll need to enter your personal information when creating an account, so make sure that the site youāve chosen has a secure connection to ensure that no one else can access that information.
To help make registering at your chosen site that little bit easier, weāve created a step-by-step guide to walk you through the registration process, so follow along below.

You can verify your account by submitting a proof of address document (such as a bank statement or utility bill) and proof of ID (such as a passport or driving licence).
Deposit Options for Online Casinos in UK
Now that youāre up and running with your account, the next thing you need to do is to fund it. Many online casino sites have a wide range of payment options, so you can choose the payment method that youāre most comfortable with. However, itās always worth checking the deposit times and the fees associated with each payment method to ensure you wonāt get hit with any nasty surprises. Letās take a look at the most popular deposit options at UK casinos.

Debit Cards
Debit cards, such as Visa and Mastercard, are one of the most popular options when making any online payment, and the same holds true for online casino payments. This is because of the security and convenience that debit cards offer, which makes depositing to your online casino a breeze. To make a deposit, simply enter your card details on to the site and enter the amount youād like to deposit. Your deposit will be in your account and ready to play within seconds.
E-Wallets
Another popular online payment method is the e-wallet. These wallets donāt require you to enter your bank or card details, making them one of the most secure payment methods available. All you have to do is enter the amount youād like to deposit, enter your e-wallet email address, sign in to your account, and approve the payment.
PayPal
One of the best examples of an e-wallet payment method is PayPal. PayPal is arguably the biggest e-wallet provider on the planet, with over 420 million active users at the time of writing. Many of the highest-rated online casinos offer PayPal as a payment option, making it a great option for UK players.
Prepaid Cards
Prepaid cards allow you to load a set amount of money onto a card and then use that card to deposit to an online casino. This has the benefit of limiting the amount you can deposit, giving you more control over your funds. Plus, it allows you to deposit without giving your card information to the casino, making it a more secure process.
Bank Transfers
While bank transfers used to be considered a slow way to move your money on and off an online casino, many sites now offer instant bank transfers through companies such as Trustly. These instant transfers allow you to make quick and secure deposits to an online casino without needing a debit card.
Pay-by-Phone
One of the more outdated but still used payment methods is the pay-by-phone method. Some casinos will allow you to make deposits using your credit on your phone or by charging your phone bill. All you need to do is select the option from the deposit method, enter the amount youād like to deposit (up to Ā£10), and the funds will be in your account! However, you need to ensure that you have a mobile number associated with your account before choosing this method.
Bitcoin
From one end of the extreme to the other, Bitcoin is the most modern payment method on this list and is fast becoming a popular option around the world. However, UK casinos have been slow to accept cryptocurrency as a payment option, and many sites still donāt support it. As cryptocurrency becomes more widely adopted in the next few years, we can expect more and more sites to start accepting Bitcoin payments.
Customer Support at the Best Online Casinos

As youāre depositing your hard-earned money, many sites recognise the importance of having a dedicated team on hand to help you if something goes wrong. The best-rated online casino sites will have a 24/7 customer support team that you can contact in multiple ways.
Phone
Some trusted online casinos will have a hotline that you can call so you can speak to a representative directly to ask your question or resolve your issue. However, this is becoming less and less common as casinos pivot to a more digital form of customer support.
Email
Almost all online casino UK sites will have an email address that you can use to contact them. However, the downside to email support is that you often have to wait a few hours to get a response, so if you have an urgent query, you wonāt be able to resolve it immediately.
Live Chat
The most trustworthy online casinos will have a live chat system where you can speak to a representative through a chat box. This gives you instant access to the customer support team and doesnāt require you to verify your details, as they can already see your details via your account.
Social Media
An increasingly common support option is social media. Many of the most popular online casinos have a social media presence, and you can message them directly on those platforms to ask questions or raise concerns about your account.
Contact Forms
Some online casinos wonāt provide players with an email address on their site but will rather have a contact form that can be filled out and sent to the customer support team. The support team will then pick up this ticket and contact you via the information you give them in the contact form.
UK Online Casinos Licensing and Legislation
The UK has long had a relaxed attitude towards gambling, especially when compared to other European countries. This can be seen as early as 2001 when the UK Government abolished the Betting Duties tax. This means that UK residents no longer had to declare their gambling winnings or losses or pay tax on any gambling winnings.
Four years later, the UK passed the Gambling Act, which legalised all forms of gambling within the UK. This Act updated older gambling laws that were several decades old and not equipped to deal with the modern forms of gambling that were now available to the public. The three main aims of this Act were to ensure that gambling remained fair and open, protect vulnerable adults and children from gambling, and ensure gambling remained crime free.
Part of the way it would achieve these goals is through new, more stringent regulations. As part of the Act, the government created the UK Gambling Commission. This independent authority would regulate all forms of gambling in the UK, with the exception of spread betting and the National Lottery. This Commission would be responsible for awarding licences to gambling companies that could meet their requirements, which included proof of funds, proof of fair games, and proof of security.
In 2014, the UK passed another Act, the UK Gambling (Licensing and Advertising) Act. This made it mandatory for every gambling company to obtain a licence from the UK Gambling Commission to offer real money games to UK players. This ensured that UK players could only play on sites that have been deemed safe and fair by the Gambling Commission.
Gambling in the UK is some of the safest in the world, thanks to the efforts of the UKGC.
Problem Gambling Help
Problem gambling is a serious problem that affects around 0.2% of the UK population, or around 130000 people. While many people enjoy gambling as a form of light entertainment, it can be extremely dangerous for problem gamblers, so we encourage our readers to seek help if they or someone they know is affected by problem gambling. There are many companies in the UK that can assist with problem gambling, and you can find information on these companies below.

GAMSTOP
GAMSTOP is a free online self-exclusion scheme that helps problem gamblers limit their access to online gambling.

This is because every online casino in the UK must cross-reference your details with GAMSTOP every time you log in or register an account as part of their licensing conditions.
Website: https://www.gamstop.co.uk/
GambleAware
BeGambleAware is an independent charity that provides information to help people make informed decisions about whether or not gambling is right for them and provides support to people who suffer from gambling addiction.

We at Slotozilla always encourage our readers to gamble responsibly, as thatās the best way to ensure that gambling stays fun. There are many things you can do to ensure that you gamble within your means, but if youāre looking for ways to manage your gambling, take a look at our helpful tips below.

Blacklisted Online Casinos Site
Despite the best efforts of the UK Gambling Commission, some sites still operate in the UK without a licence. These casinos have been blacklisted by review sites such as ours due to their lack of security and scam potential. While the UKGC is often quick to clamp down on these dodgy sites, thereās still a risk that you might stumble across one accidentally. For a comprehensive list of blacklisted sites, check out legitgamblingsites.com.
To avoid playing at any of these illegitimate sites, we recommend that you only choose sites featured on our UK online casinos list. Our team of experts ensure that we only recommend fully licenced and secure sites, so any one of our sites is a safe bet.
