How We Rate Betting Sites
A site’s reputation reflects the relationship it has with its players. That’s why we speak with gamblers and industry experts to uncover every detail in our reviews.
It takes trust to deposit your real money online and we want you to know, if we trust a partner, so can you. This is why all sites must be legitimately licensed and regulated, as well as keeping your data safe with the best encryption technology.
A necessity of all online gambling sites is a range of secure banking options. From there, it’s imperative all sites provide high payout percentages with fast withdrawals and a fair RTP.
All our sites are expected to provide new players with a welcome bonus, as well as rewarding loyal players with bankroll boosting promotions. We also check for any unfair T&Cs, meaning you can bet with confidence.
Top sites will offer extensive customer support, which is why we review this rigorously. While we always encourage our users to get in touch, we understand the importance of having your questions answered efficiently and by a real person.
Whether you're playing online from your computer or mobile device or tablet, our top recommendations can match your lifestyle. A top online casino needs to be compatible with multiple devices, so you have the freedom to play wherever and however you want.
Whether through the range of games or sports to bet on, the option to play for free or even choosing between software providers, players must be provided with options when gambling online. Aside from this, we require all partners to meet a high standard with the graphics of their games and localization to accommodate for players from around the world.

How We Rate Online Casinos in the UK

In order to bring you the best online casinos, we follow a very strict review process. Our team of experts check every online casino thoroughly over a long period of time to ensure accurate findings. These are the main aspects that we analyse and rate during online casino reviews:

Bonuses & Promotions

Casino bonuses and promotions are very important for online players. The offers can provide free funds for enjoying the games, especially with generous welcome bonuses. We make sure to check the finer details, including the wagering requirement and game contribution rates, something which is often overlooked. A high-rated bonus must be easy to claim and actually beneficial for the player.

Safety & Security

We always prioritize online security during our reviews. Every site we recommend has to have state-of-the-art SSL digital encryption and ensure safe banking. Operators must also be licensed in the UK by the Gambling Commission. Our experts also check the privacy policy and reputation of the company.

Banking Options

Any online casino we recommend has been reviewed for the quality and variety of their banking options. The cashier should accept deposits by credit and debit cards, e-wallets, prepaid cards, and bank transfer services. Popular options in the UK include PayPal, Visa, and MasterCard.

Payout Speed

The time it takes to withdraw real money from an online casino can be a good indicator of its services and reliability. Players should be able to easily withdraw their winnings whenever they wish to. The industry standard for processing payouts is of 1-2 banking days. Some operators are already offering fast withdrawals that only take 12 hours.

Game Variety

The collection of games is always a key aspect of an online casino. During the review, we check the size of the library and also the level of game variety. The best online casinos don't just offer a lot of slots, but also have plenty of table games, video poker machines, a full live casino, and other options.

Mobile Experience

Over 50% of all online gambling in the UK is done by mobile, so it's absolutely essential an online casino operates an excellent mobile platform. For a smooth mobile experience, the casino has to be easily accessible on iOS and Android devices and have a user-friendly interface with loads of games.

The process has been proven to highlight the strengths and weaknesses of each online casino, online sportsbook, and online poker site we review. The ratings also make it easy for readers to compare multiple options at a glance.

We are constantly updating our reviews to make sure that they have the correct information. This is especially important for bonuses and promotions, but also for games and banking options. You can check out our reviews for Sports, Casino and Poker right here:

Best Online Casino Bonuses

Online casinos will often have bonuses for rewarding and incentivising players. These will provide extra playing funds, free spins, cashback, and other types of rewards. Casino bonuses can start from the moment you sign up, continue on the first deposit, and then be available as you play on the site.

To better understand how the different types of casino bonuses work and how you can benefit from them, we have a detailed rundown right here:

No Deposit Bonus: No deposit bonuses are actually quite rare and sought-after in the UK. As the name suggests, these are bonuses that don't require users to deposit funds to play real money games. Usually, new players can earn no deposit bonuses just by registering with the casino. This is the case with 32Red Casino and its £10 sign-up bonus. After receiving the no deposit deal, you can use the funds to try out the games for free. The winnings are yours to keep, up to a certain limit, and you can even withdraw them after completing the wagering requirement.

Welcome Bonus: The casino welcome bonus is the offer available on your first deposit. This can sometimes extend to include multiple deposits as a welcome package. The standard welcome bonus is of 100% up to £200. However, some of the best online casinos come with much more appealing offers.

Reload Bonus: Reload bonuses are the most common casino offers in the UK. These are available on deposits after claiming the welcome bonus. Some casinos can have weekly reload bonuses for players to significantly increase their bankrolls. You just have to select the offer and make a qualifying payment.

Match Bonus: A match bonus is basically a 100% offer on a deposit. For example, if you deposit £100 and claim a match bonus, you will also receive an extra £100 for free. Every match bonus has minimum and maximum limits, usually of £10 and £100. However, some offers can even exceed £500.

Free Spins: With online slots being some of the most popular casino games in the UK, casino operators will often offer bonuses in the form of free spins. In most cases, the bonus rounds are only available on selected slots and the winnings are subject to standard wagering requirements.

Mobile Bonus: Casino mobile bonuses are exclusively available on the mobile platforms. In order to claim them, you will have to connect on the mobile casino, from your phone or tablet. Some mobile bonuses are instantly available when signing in, while others may require deposits from the mobile cashier.

Loyalty Bonus: The best online casinos in the UK have dedicated loyalty programs for generating rewards. Players earn comp points when they bet real money and can unlock various benefits. Loyalty bonuses can improve based on the amount of points earned within a month.

Referral Bonus: As a registered player, you can refer the casino to your friends and get bonuses through the referral program. They just need to use your link or code when signing up. Once they make their first deposit, you will receive a referral bonus for free.

Best UK Casino Software Providers

Software providers are the backbone of the online casino industry, providing top games and innovating with new titles. Each developer has its own style and library of games. Casino operators can choose to only use one provider or several for a larger collection.

There are over 100 major software providers in the UK. However, only a few of them really stand out. You can learn more about the best casino software developers in our guide:

Microgaming: Microgaming is one of the most popular software providers in the business. The company was founded back in 1994, making Microgaming also one of the oldest developers of online casino software. Over the decades, the provider has created a massive portfolio and now has over 600 casino games in its active collection.

Microgaming stands out with its impressive level of variety. It has various table games, video poker games, and even instant win options. However, its biggest strength is the outstanding selection of online slots. Players are sure to recognize popular titles, such as Mega Moolah, Thunderstruck II, and Immortal Romance.

IGT: IGT is the largest developer of slot machines and gaming cabinets for land-based casinos. This multinational gambling company started in 1975 and merged with Gtech Corporation in 2015. It now has offices in London, Las Vegas, Rome, and other key locations.

With the growth of online gambling, IGT also expanded online and brought its many iconic slot machines to the internet. It's now a hugely popular software provider at some of the best casinos in the UK. Some of its biggest titles include Cleopatra, Golden Goddess, and Pixies of the Forest.

NetEnt: Formerly known as Net Entertainment, NetEnt is a software developer based in Sweden. It was established in 1996 and quickly became one of the top studios in the industry. NetEnt stands out with its superb video slots, which often have immersive themes and very entertaining bonus features. It has also expanded to offer a few live dealer games for more variety.

NetEnt now has a collection of over 300 slots, many of which come with mobile-optimized versions known as Touch. It offers massive progressive slots, such as Hall of Gods and Mega Fortune. However, its most iconic titles are Starburst and Gonzo's Quest.

Playtech: Playtech is another well-established software provider that UK players are very familiar with. The company started in 1999 and it has been one of the pillars of the online casino industry for decades. It's now the largest online gaming software supplier listed on the London Stock Exchange and operates in 20 regulated jurisdictions.

While Playtech offers gaming products and software solutions on multiple platforms, it's best known for its online casino games. The current collection exceeds 200 titles, covering slots, tables, specialties, and even live games. Some of Playtech's most successful slots were created in collaboration with movie studios, like it is the case with Man of Steel, Top Gun, and Gladiator.

Evolution Gaming: Unlike the other software providers on our list, Evolution Gaming is not known for its slots. Instead, this is the best developer of live dealer games for online casinos. It was founded in 2006 and won countless awards over the years. The company continues to expand and increase its offering of games.

Players can access a variety of live dealer games through the dedicated lobby powered by Evolution Gaming. Not only does it have multiple versions for the classics, like roulette, blackjack, baccarat, and poker, but it also comes with plenty of specials. Dream Catcher is one of its most popular games, along with Lightning Roulette.

Play'n GO: Play'n GO has been quickly rising to the top over the past few years and it is now one of the leading software providers in the world. Established in 2005, the company had a somewhat slow start but it has always focused on quality and entertainment value. It now has around 200 casino games in its collection, most of which are modern video slots.

The developer is known for its detailed themes and impressive graphics for the spinning reels. It also has plenty of unique games that provide a different gameplay than what most players are used to. Popular Play'n GO slots include Book of Dead, Reactoonz, and Rise of Olympus.

UK Gambling Laws

Online gambling in the UK is legal under the Gambling Act 2005. The UK Gambling Commission is in charge of licensing and regulating online gambling operators for casino, sports betting, poker, bingo, and lottery games. Unlike in many other countries, the laws for gambling in the UK are clear and detailed. All players must be of at least 18 years of age and all operators must have valid licenses from the UK GC.

The Gambling Act 2005 was passed with the goal of providing a safe environment for online gambling in the UK. It helps prevent gambling crimes and also fights betting disorders. Players are required to verify their identity and source of income before betting. Recent amendments have banned free games for users who aren't signed in and verified as to not encourage problem gambling. Also, for this reason, operators have limited advertising opportunities on local banners, TV, and radio channels.

On 14 April, 2020, the Gambling Commission officially banned the use of credit cards for online gambling. The reasoning being that credit card gambling can cause significant financial harm for some players. This restriction also applies to e-wallets, such as PayPal, that have a linked credit card.

New gambling regulations, like betting limits and restricted VIP programs, are being discussed and it remains to be seen how they will be implemented.

Disclaimer: This is not legal advice and we recommend seeking independent advice for more information about betting in the UK. Laws are constantly changing and while we strive to keep up with the regulations, the information may become outdated.
