UK Online Casinos List

Before signing up for any online casino, ask yourself: What do you want out of an online casino? Why do you want to play at one? What are your favourite games? Once you know the answers to these, you are ready to find the best online casino site for you!

Different players will have different criteria for what they believe is the best online casino. For some players, casino bonuses are crucial. For other players, it is the number of live casino games that makes or breaks their choice.

When looking for the best online casinos, consider factors such as the variety of games, the quality of customer support, and the safety and security of the site. Ultimately, it’s important to do your research and choose a site that meets your individual needs and preferences.

Here at CasinoGuide we have put together a comprehensive overview of the best UK online casinos. Whether you love playing slot machines or go head-to-head in a live casino game, our experts have put together the best casinos for the most popular criteria.

What Do UK Casino Sites Have To Offer?

MOBILE CASINOS

Many of the best online casino sites are fully compatible with mobile devices, including having a dedicated mobile app to cater to online gaming on the go, from anywhere!

Casino sites are well aware that most players are playing via mobile and therefore must offer the same great experience across devices. Discover the UK online casinos with the best mobile experience.

LIVE CASINOS

Live casino is streamed directly to your laptop, mobile or tablet in full HD and in real time, where you get to play against a real live dealer as you would at a traditional land-based casino.

Almost all UK online casinos have a live casino lobby. On our live casinos page you can choose between the best UK-licensed casinos for live dealer games.

NEW ONLINE CASINOS

So many new online casinos are set up every year, and to be amongst the first to discover all of the latest, check out the new online casinos page.

After trying and testing the UK online casinos that have just launched, we will add them to the page. We will never promote a new UK online casino if it does not pass our rigorous tests.

All of the sites listed on Casino Guide have been tried and tested to deliver the best gaming experience possible. Before you get started, take a look at our individual casino reviews to discover what is in it for you.

How We Rate UK Online Casino Sites

All UK online casinos which are recommended in our list above have been rated and reviewed by our expert team. We pride ourselves on our excellent reputation amongst casino review sites. But how do we review casino sites?

We know there’s a wide variety of choices when it comes to online casinos. To aid you in your search for the best, we’ve written highly comprehensive and thorough reviews, by always following the CasinoGuide 6-point review process:

• Standout Features – most UK casino sites have something that makes them stand out from the crowd. Are they a particularly trusted brand, or offer a more enjoyable experience than the normal? We will find out on your behalf.
• Bonuses – one of the biggest factors affecting player decisions when choosing between online casinos in the UK. We assess the offers and the relevant terms attached.
• Games – the crux of the online casino experience. If you’re looking for top casino sites Great Britain, it’s important to consider the range and quality of games on offer. We tell you who makes the games that are featured, and some of the most popular variants of slots games, table games, and more.
• Mobile Experience – most players like to have the option to continue playing on their mobile. That makes the mobile experience very important!
• Payment Options – everything you need to know about making deposits and withdrawing your winnings.
• Support and Security – we assess all the available options you have for getting in touch (i.e. live chat, email, and phone), examine the casino’s security, and see who they are licensed and audited by. We also look at how they help players to gamble responsibly.

Other UK Casino Features

HIGH ROLLER CASINOS

High roller casinos are those that cater for players with bigger budgets. In reality, any UK casino that caters for these types of players is indeed a high roller casino. High Rollers or VIP’s, often get special treatment as a gesture of goodwill for their continued loyalty towards an online casino site.

VIRTUAL REALITY CASINOS

The idea of using virtual reality in UK online casinos began in around 2017. SlotsMillion swiftly launched their own VR casino experience, complete with stunning city views and a selection of the most popular slot titles. Since then, NetEnt launched Gonzo’s Quest in VR, which can be played without downloading the software.

GAMIFICATION CASINOS

Online casino gamification is still a new trend, but there’s no doubting the popularity of the concept. Essentially, with gamification, casino players will earn points and increase levels as they play casino games. Every milestone reached is rewarded with an upgraded status, as well as special bonuses and other rewards.

REAL MONEY CASINOS

Some players like to try games for free and play around a bit before they get started. But if you’re someone who wants to just dive into the real money play, this is the page for you. There’s definitely something incomparable about the thrill of playing for that big real money win! Take your pick from the most reputable real money online casinos licensed in the UK, and get straight into the action with a juicy deposit bonus.

Types Of Casino Bonuses For UK Players

Deposit offers, welcome bonus, free spins… It’s important to understand the many different types of casino bonuses. The bonuses on offer are so massive, sometimes even extending into the £1,000s.

Wagering Requirements

This is one of the most important conditions attached to casino bonuses. Wagering requirements are designed to prevent players from taking unfair advantage of bonus offers.

A typical wagering requirement could be ’35x’ – meaning you need to bet the bonus amount 35 times before withdrawing it. The details the wagering requirements and other terms can be found in several places:

• We state them for you at the top of each casino review here on CasinoGuide.
• They are clearly displayed in our recommended UK online casinos list.
• They will be visible if you go to the casino site.

UK Online Casinos On Mobile

Gone are the days where players had to be shackled to their desktop PC’s to play their favourite casino games. The vast improvements in mobile technology allowed casino providers to make rapid changes to their mobile platforms, creating an improved mobile experience for their casino players.

Why Should UK Online Casino Players Play On Mobile?

There are a number of benefits to playing at UK online casinos on your mobile – specifically:

• Regular bonuses pushed to your device notifications
• Play anywhere, anytime
• Get to your favourite casino games quickly and easily

Should I Play at UK Online Casinos With My Mobile Browser Or On An App?

There’s some debate between players whether mobile browser or app is better for mobile games. At the time of writing, the experience is roughly comparable – browser and app both have their pros and cons.

You are using the same account regardless, so the choice is up to personal preference. Some people would rather save the storage space on their device for other things, while some prefer to have the slicker interface that comes with a native app.

Biggest Online Casinos in the UK

There are players who stick with the classic slot and table games that they know best. Other players prefer to try out the newest games as soon as they are released and spice up their gameplay with as much variation as possible. If you are looking for the biggest online casino, you’re looking for a website that continuously expands its selection of games.

When we talk about the biggest online casinos on the web, we’re looking at sites that host at least 2000 different games on their platform. If you’re looking for a casino with a massive game library, then the following brands will definitely tickle your fancy.

Am I Safe When Gambling Online In The UK?

UK Online casinos are completely legal and regulated. All legal UK casino sites hold a license from the Gambling Commission – the official Government body charged with ensuring the fair and legal operation of all gambling services offered in the UK.

The Gambling Commission Regulates UK-Licensed Online Casinos

When the Gambling Act 2005 was passed, thereby making both online and offline gambling legal in the UK, the Government formed what is known as the Gambling Commission. Put simply, the Gambling Commission is the ultimate authority when it comes to all kinds of gambling in the UK.

It is a legal requirement for any online casino offering their services to UK players to have a license issued by the Gambling Commission. This license indicates that the casino abides by all of the various rules set out by the Gambling Commission.

Why Is It Important?

Rules and laws enforced by the Gambling Commission include everything from consumer protection, responsible gambling measures, and dispute procedures – allowing you to play with complete confidence.

A Gambling Commission license is one of the hardest to get in the gambling industry. UK-licensed online casinos are held to some of the highest standards in the world.

Every UK online casino listed here on CasinoGuide.co.uk holds a license from the UK Gambling Commission.

How To Decide Which Online Casinos Are Trustworthy?

Despite the above, not all UK casinos were created equal. Fortunately, we know how to tell a good casino from a less worthy one. You don’t need to worry about this too much, as we’ve done the hard work for you. Our list of the top online casinos in the UK comprises of the best safe online casinos only! It’s easy enough to tell, when you know the right questions to ask:

Is the casino licensed?

Any online casino operating in the UK without a license from the UK Gambling Commission should be avoided completely.

How do they deal with complaints?

Good customer service is key to any reputable online casino. Avoid websites that do not respond to complaints or send out generic responses. All our UK-licensed casinos have a live chat option to assist the player virtually in a timely and professional manner.

Are their bonus terms fair?

Casino bonus wagering requirements are, as a rule, quite high. It’s the nature of the game. But if a casino is applying requirements that are significantly above average, that’s a red flag for us.

How well do they promote responsible gambling among their players?

One of the most important obligations that online casinos must fulfill is to provide effective and timely support for players who may be suffering from gambling addiction. Thanks to the Gambling Commission this is a requirement of any UK-licensed online casino, but if they go over and above the minimum, this is a good signal of their trustworthiness.

KYC Checks and Tax on Winnings?

Are there Winning Taxes?

UK players are some of the luckiest in the world as they do not pay taxes on gambling winnings (thankfully player taxes were abolished in 2001 and casinos are responsible for paying a flat rate of 15% tax of earnings instead of the player).

What Is The KYC Check?

KYC stands for Know Your Customer, and is a check undertaken by casinos (and other regulated bodies like financial institutions) through submission of verifiable ID through a secure online gateway.

Put simply: your ID is compared with the information you entered during registration, and either confirms or denies you are who you say you are.

By law, all online casinos in the UK are required to verify the name, address, and date of birth for all online players who sign up at their casino.

Why Is It Required?

KYC is necessary to ensure that all players are over the age of 18 and therefore legally able to gamble at UK online casinos. Regulations have been tightened by the UK Gambling Commission in recent years in an attempt to reduce the number of underage gamblers in the UK.

Casinos have other requirements to meet which necessitate KYC checks further. Anti-money laundering regulations necessitate checks to ensure that your money hasn’t come from an illegal source, particularly if you’re making large deposits to your casino account.

UK Gambling Legal Timeline

The UK is known as one of the best gambling jurisdictions in the world. In 2005 they overhauled all existing legislation and created the 2005 Gambling Act. Here’s an overview of the legislation they’ve enacted since.

Why Is Gambling Regulation Good For Players

The UK is one of the most regulated gaming markets and jurisdictions, which works out perfectly for players and creates a safe, worry-free gambling environment.

By stopping unlicensed casinos from operating, as well as providing a whole host of other protections, the UK Gambling Commission is arguably one of the best licensing jurisdictions in the world.

Are Players Hindered By Regulation?

For the main part, the regulation extends to the casino and how they engage with the player, forming a system of protections and rules.

This includes everything from how bonuses are advertised, to the separation of player funds, and creation of a safe gambling environment.

As licensing, certification, and RTP percentages must be obtained and published for all UK-licensed casinos, you know exactly where you stand with casino sites in the UK.

And crucially, you know that there are systems in place to hold the casino accountable by consumer and gambling laws if something goes wrong.

UK Online Casino Games

From Blackjack and Craps, to Slots and Roulette, online casinos in the UK have got it all. Here at CasinoGuide UK, you can find lists of online casinos that are most highly recommended for your particular choice of game. These can be found on our casino games page.

Whatever you want to play, you will find the ideal online casino website to play at right here on CasinoGuide. In addition, we provide in-depth strategy guides on all the most popular games, for beginners and advanced players alike.

Are Online Casinos UK Games Fair?

Here at CasinoGuide UK, we only recommend the best online casinos which are regulated by the Gambling Commission, meaning they have been checked for fair gameplay practises. By playing at one of the top online casinos listed here, you avoid running the risk of playing games with odds that are more tilted towards the house than other casino websites.

With that said, it is important to note that all online casino games give the casino at least a slight edge over you, the player. This ‘house edge’ is there to ensure that the casino wins more than half of the time on average, over the long-term.

This is par for the course in casino games – you can find it in our game guides. Here are a couple of examples:

• In Roulette, the house edge is relatively easy to understand. In European Roulette, there is one 0 pocket, and in American Roulette there are two, which in effect doubles the house edge – as landing in a 0 pocket means that all bets (except a bet on 0) lose.
• In Blackjack, the dealer has an edge due to the fact that he will always play his hand last – and if the player busts, the dealer collects their bet by default. In some Blackjack hands, the dealer doesn’t even need to play his cards.

Try Playing For Free

Many UK online casinos have demo or practice mode for their Slots and RNG table games. This means if you sign up you can play for free, but without the chance to win real money.

Signing up at a UK online casino will require you to verify that you are 18 years or older.

Playing for free gives you a taste of the action at no cost and you get to try out different software, variations, and strategies while you’re at it!

Game Software Providers

Casino games vary from producer to producer, each with differing attitudes to graphics, game concepts, bonus rounds, game limits, jackpots, maths – basically, every game detail.

This means there’s an element of personal preference in deciding which developer’s games you prefer – exploring casino games libraries on casino sites in demo mode is often the best way to find your preference.

After all, the games provided by a UK online casino should be a crucial factor when you’re deciding if you want to play there.

Who Are The Main Casino Game Providers For UK Casinos?

Several market-dominating producers form the basis of most game libraries at online casinos in the UK. These are some of the biggest casino software providers in terms of library size and player following:

• NetEnt
• Microgaming
• Play’N GO
• Playtech
• Evolution Gaming
• Big Time Gaming

The best UK online casinos make use of the rich cornucopia of casino games on offer to create plentiful lobbies of the best and latest casino games. This, in turn, attracts new players while keeping existing players interested. If you want to know more, have a look at our complete guide to software providers and games.

Combining Established Brands With Hot New Titles

The biggest casino software providers have hundreds of games in their collection, which reflects just how long they’ve been operating for.

But these big hitters often also own smaller studios; a recent strategy is to acquire new studios to bolster and improve their own game portfolios – while the smaller studio benefits from greatly increased distribution under the brand of the established software provider.

For example, under Microgaming, you’ll also find games from the following studios:

• Lightning Box
• JFTW
• 2By2
• Rabcat
• Old Skool
• Fantasma
• Triple Edge Studios
• BlaBlaBla Studios
• Foxium

This makes Microgaming software particularly competitive and current, with several new games released each month.

Fierce Competition Between Providers

Microgaming’s biggest competitor is NetEnt, an innovative studio which produces all its games created in-house. This guarantees the same sublime quality and slick graphics across all titles, albeit across a smaller portfolio (Microgaming has 650+ games, NetEnt 250+).

NetEnt is reputed amongst online players for driving innovation in games concepts, being at the forefront of graphics technology and for keeping the other software producers on their toes. The size of Microgaming’s game lobby is matched only by Playtech who have created more than 300 games.

There are many other rival software providers, big players who have been around since the 90s like Play’N Go or Scientific Gaming. Add to this all the newer breakaway software providers such as Yggdrasil, which split from NetEnt, or entirely new studios like Big Time Gaming and Red Tiger – each with something unique to add to your casino experience, and you get a highly competitive casino games marketplace.

Payment Options at UK Casinos

Due to the heavily regulated gambling market in the UK, online casino transactions are protected by consumer law and there are plenty of fast, safe, and secure payment methods available.

The more payment methods a casino offers, the wider range of players they can attract, and the more flexible it is for you, the player.

The best UK online casinos offer the following types of payment options:

• Debit cards
• E-wallets
• Vouchers or prepaid cards
• Bank transfers
• Mobile phone payments

How Long Do Payments Take?

For most payment methods, deposits are instant and processed through a secure payment gateway. Here’s how a few of the more popular options work:

• For debit card payments, you will naturally need to provide your card details
• E-wallets and pay by phone payments like PayPal or Boku could be seen as more secure as they don’t require your card details.
• Similarly, vouchers and prepaid cards like Paysafecard allow cash users to play by buying the card or voucher in participating local shops.

Withdrawals can usually take up to 3 working days, but VIPs can usually access express withdrawals. The casino must first process your withdrawal request, the best online casinos do this within 24-48 hours and then send the money to your account or e-wallet.

Responsible Gambling Resources

• SELF EXCLUSION
• REALITY CHECK
• TIME LIMITS
• BETTING LIMITS

When The Fun Stops, Stop

As an addictive behaviour, gambling should only ever be a fun activity, not a behaviour you cannot control or feel compelled to engage with. To encourage awareness of gambling behaviours casinos must provide players with:

• Information and support regarding problem and responsible gambling
• Deposit limits
• Playing time limits
• Time-outs
• Permanent exclusion

All gambling operators should also train their support services to recommend these tools and refer players to gambling support services where needed. The best casinos also have systems in place to keep an eye on their players, checking for irresponsible or addictive behaviours.

If you are in the UK and feel that your gambling is out of control or you require support to gamble responsibly, you also have a wealth of charity-based services at your disposal:

• GamCare: provides free support and counselling aimed at prevention and treatment of problem gambling.
• NHS Gambling Addiction: The NHS also runs a referral service for those struggling with gambling addiction.
