This site has a variety of ways for British punters to bet, including a slick platform.

Another of the top British online casino sites is Betway. This is a hugely popular gambling site which makes it easy for you to get started in style. The William Hill casino is also a solid option from a highly recognisable name that is worth checking out too. 888 Casino website also comes from a global brand that has a top-notch selection of games for Brits.  

UK gamblers have an enormous choice of online gambling sites and casinos to choose from. As long as you’re aged 18 or over, you can open an account and play jackpot slots or table games like roulette and blackjack. That’s why we carefully test each and every UK casino when compiling our recommended list.

Range of Slots & Games: The best casinos in UK will offer a healthy selection of video slots, table games, and instant win games for players. You’ll be able to select games from a broad range of developers and add titles to your Favourites list.

UK Casino Games

A great online casino will let you play games through your web browser or smartphone. There’s no need to download a thing as most modern games are programmed to work in HTML5. Why clog up your hard drive when you can play online?

Licenced by the UK Gambling Commission: By law, all UK online casinos must be licenced by the Gambling Commission. Sites will be regulated to ensure payouts are fair and players have access to deposit limits.

Reliability & Security: The best casinos run a safe and secure platform for online gamblers. Your personal data will be protected and your funds will be segregated in secure bank accounts away from the casino’s day-to-day costs. Plus, games and slots will be audited and payouts regularly tested.

Mobile Gaming: We also check the casino’s mobile capabilities. You should be able to download a native mobile app for your Apple or Android device. Play hundreds of slots and table games on the move through your smartphone.

UK Casino Payment Methods

It’s vital you get your money in and out of a casino account quickly. A slow casino means you may miss out on a promotion or slots jackpot.

Luckily, the best online casinos offer fast banking every time. You will be able to make instant deposits with your debit card, e-Wallet, or bank account. Better still, you will avoid transaction fees at the top gambling sites. Plus, the best casinos will let you deposit as little as £5-10 at a time.

Withdrawals should be processed quickly too. Just open the cashier and select an available cash-out method. Typically, the best casinos will process withdrawals back to the method you used to deposit with.

You’ll have to wait a day or two for your money, but the top casinos sometimes offer fast cash-outs for some methods. And like deposits, you won’t have to pay a penny when you withdraw winnings.

Casino bonuses are great for giving your bankroll a welcome lift. It’s not good enough having a welcome bonus – all casinos offer those – but they need to be generous and realistic.

For example, imagine you are claiming an online casino bonus worth 100% up to £1,000. You decide to take advantage by depositing the full £1,000 and receiving £1,000 in matched funds. However, the wagering conditions are listed as 50x, which means you must gamble £50,000 (50 x £1,000) in order to release just £1,000 in free money.

Good casinos will spread a host of bonuses. Look for an online casino that offers a mix of deposit match deals and no-deposit bonuses. A no-deposit bonus is great if you want to test the waters at a casino without opening your purse or wallet. Just sign up, receive no-deposit bonus funds, and play eligible games. It’s as simple as that.

The best online casinos in the UK are just a click away. Choose one of our top-rated gambling sites and make your first deposit. You’ll receive a welcome bonus right from the off so you can start earning as you spin.

And don’t forget to join a VIP programme which promises benefits like birthday bonuses and faster cash-outs. You’ll need to maintain your gaming level during the month, but this shouldn’t be hard if you pick the right games and keep winning.

Types Of Bonus Offers

The most popular online casinos in the UK entice you to sign up thanks to generous bonuses. This is something that begins right away, with a welcome bonus to get you settled in. The following are some types of deals you can look for.

  • A boost to your first deposit. This could see you get an extra 100%, 300%, or more added to your funds. You’ll need to play through the winnings a set number of times before you can withdraw them.
  • A batch of free, real-money spins may be awarded on a popular slot.
  • A cashback deal lets you recover part of your money if you lose.
  • Free Spins offers give a nice chance on specific slots, such as Book of Ra or Sarburst at Unibet Casino.

Online casinos have been legal in the UK for over two decades. In fact, the United Kingdom has a long history of regulating the best online gambling sites. You can play online slots or table games like roulette totally legally from your PC or mobile. Best of all, you can deposit and withdraw real money and secure casino bonuses like free spins.

Legal online casinos must be regulated and licenced by the UK Gambling Commission. Without that approval, a casino won’t be able to take your business. In fact, they will be breaking the law if they allow you to open an account and make a deposit.

Every UK online casino must be properly licenced and adhere to strict rules of conduct. They must also provide a safe space for gamblers to play in. You should be able to enjoy accurate and easy payments and your personal details must be protected.

The best UK casino sites offer cutting edge software and the latest games from the biggest developers. Here’s what you can expect from top casinos in the UK.

Licenced by the UK Gambling Commission

Under current UK internet gaming laws, all online casinos must be licenced by the UK Gambling Commission. Casinos must comply with the conditions of their licence. They might also have to undergo a compliance assessment to gauge their ability to run an online casino operation.

The Gambling Commission also provides guidance on anti-money laundering and ensures casinos protect children and vulnerable people from gambling online.  

A great range of games and slots

Legit UK casino sites online will boast games and slots from UK-licensed software providers. Software providers can only supply games that have been independently tested before they hit the casino lobby.

You will be able to choose from classic and 3D slots, branded games, or the slickest live casino titles. Play roulette from 10p a spin or hit the VIP tables and play blackjack for up to £10,000 a hand.

Huge promotions and loyalty schemes

All good casinos should provide some form of welcome bonus. A welcome bonus might be a deposit match where you can earn free cash by meeting the stated wagering requirements. Many welcome bonuses also include free spins on popular slots.

Regular gamblers will be rewarded with a loyalty scheme. VIP programs award points and benefits for the gamblers who maintain their sessions during the month. Benefits range from a personal VIP manager to exclusive invites to sporting events.

24/7 customer support, safe transactions and payment options

Good trusted casinos provide English-speaking support via live chat, phone or email. The best sites also provide a detailed Help Centre with information on payments, security, and everything in between.

You can legally play games for real money in the UK. But it’s important to have a choice of secure banking options available.

Top UK online casinos let you deposit via card, e-Wallet, bank transfer or prepaid voucher. You should also have access to fast cash-outs with reverse withdrawals available if you change your mind.

The UK’s online casinos give you numerous ways to add funds or withdraw your winnings. Alongside debit cards, one of the most popular ways of doing this is with e-wallets such as PayPal, Skrill, and Neteller.

Pre-paid cards such as the Paysafecard give an alternative if you don’t want to use your main debit account. You will also see that cryptocurrencies such as Bitcoin are becoming more popular in some of the top British casinos too.

Audited software and trustworthy games

Under UK licensing laws, game providers must be audited by approved testing labs like eCOGRA. Labs regularly test slots and games to make sure their RTP (Return to Player percentages) are accurate and their RNGs (Random Number Generators) fair.

Game Fairness

All online casinos in the UK must go through rigorous software checks. All outcomes of games of chance like roulette and slots are determined by random number generators (RNGs). These are independently checked by external testing labs in compliance with gambling regulations.

Testing houses like GLI and eCOGRA are approved by the UK Gambling Commission. Legalised casinos will have to have used an approved testing agency before acquiring a gambling licence.

Regular Audits and Verified Payouts

Legal UK casinos also have regular audits performed on their software platforms. Testing labs can provide audits on the casino’s security, encryption, and payment tools. They will also verify the casino’s overall payouts to players over the long term. You’ll be able to view audit certificates on the casino’s homepage.

Segregated Player Funds

Legal online casinos in the UK must keep player funds properly segregated. This is to protect the money from the casino’s overall operating costs. Money must be available for players to withdraw whenever they like. Plus, legit casinos will always have enough money in reserve to cover any jackpot wins and bonus payouts.

Responsible Gambling

All legal online casinos must also provide resources to customers to prevent problem gambling. Operators work with the UK Gambling Commission to raise awareness of programmes like GambleAware and GamStop. They will also provide links to website blocking tools like CYBERsitter and GamBlock.

In addition, online casino sites will let you set your own deposit limits. Plus, you’ll be able to self-exclude if you want a few months off.

Unearthing Illegal Online Casinos

With so many casinos online, it can be hard to sort the great sites from the dodgy ones. We never recommend you gamble at offshore casinos and only trust gaming sites that have UK licences.

Poor Gaming Licences

Illegal sites won’t have UK Gambling Commission licences. They may also operate under a licence from an unreliable gaming commission.

Bad Operators with Several Casino Skins

Some online casino operators run several skins under the same banner. But if one casino has a bad reputation for fairness or payouts, chances are they all do. Always look for blacklists where a casino has scored poorly in one or more of these areas:

  •         Security and encryption
  •         Slow or non-existent payouts
  •         Slow payouts on casino bonuses
  •         Spam marketing
  •         No UK licence or a licence from an unreliable jurisdiction

Bad Game Selection

Illegal casinos will offer a poor selection of games and slots. The software developers won’t be licenced in the UK and there will be evidence that games are available in countries where online gaming is banned.

Pirated Software & Slots

Some illegal casino sites are far worse and use pirate copies of popular slots. They will steal a developer’s software and incorporate their games into their sites. But there is no way of verifying payouts or checking that the RNGs are legit.

Illegal casinos may have terrible customer service where messages go unanswered for days or weeks at a time. It will also be difficult to lodge an official complaint if anything goes wrong.

All of these indicators will help you root out rogue casinos online. You can also search the web for casinos that have drawn lots of customer complaints.

The biggest issues players have is non-payment of funds or bonuses. You should also check to see if the casino has an official testing lab that conducts regular audits.

Only legal, safe gambling sites make it into our recommended list. All of our picks have gone through the fit and proper checks to ensure they provide a great experience. Bonuses must be honoured and cash-outs processed quickly. You should also have the means to complain if anything goes wrong.

Only trust the top legal UK casinos in 2021. Sign up in the knowledge that your personal data and funds are totally secure. Then you can get on playing the biggest table games and jackpot slots in town! 

Quick History of Online Casinos in the UK

The UK has one of the longest-established and most reputable online casino industries in the world. British online casinos are regulated by the UK Gambling Commission, which ensures that only professional sites that look after their customers can operate here. There are many excellent choices to take into account when you start to look for the UK best online casinos.

Online casinos in the UK offer an unrivalled selection of slots and games and some of the best bonuses on the web.

The online casino industry has grown over the last 20 years. The 2005 Gambling Act was the first piece of legislation to properly regulate online gaming in the UK. It also saw the setting up of the new UK Gambling Commission.

Under current laws, UK gamblers over 18 can play online or on mobile for real money. They can win real money jackpots on hundreds of games, and even fund their accounts at participating land-based casinos.

UK casino players now have dozens of great gambling sites to choose from. Games are provided by some of the biggest software developers in the world. Gambling is safe and funds are properly protected.

Casino gambling has been around in the UK for decades. But the relaxation of British gaming laws only happened in the mid-2000s.

After the 2005 Gambling Act was introduced, UK players were able to access hundreds of casinos online, but the reliability varied from site to site. It was only nine years later that the Gambling (Licensing & Advertising) Act of 2014 put in a proper framework for UK casinos.

Under the 2014 law, any online casino operating in the UK must have a Gambling Commission licence. Software developers too must acquire a UK licence in order to supply games to the UK market.

The conditions have toughened since 2014 too. It’s often hard to try play-money slots and games at casinos if you’re in the UK and don’t have a casino account. And to comply with fraud and security requirements, you must provide proof of ID and home address in order to gamble for real money online.
