How Do We Review the Best Casino Sites

At Gambling.com we’ve spent years with our team developing a system to evaluate the very best in online casinos for the UK. Although there are hundreds of casinos available, not all make it into our top lists and only the very best qualify.

Any casino site which doesn’t offer transparency as to how it evaluates casinos isn’t to be trusted with your money or your time. Here’s how we decide what makes the cut:

  • Bonus offers

    In a competitive world, any online casino in the UK must have a wide range of promotions and bonus offers for both new and existing players including a comprehensive program for VIPs with transparent terms and conditions and fair wagering requirements. Is there a bonus code required to claim your offer? Is there cashback for high rollers and VIPs? We check it all out for you.

  • Game variety

    Top casino sites in the UK must offer a full complete online casino service consisting of live dealer play, table games such as blackjack and roulette, progressive jackpots and several hundred of the best slot games as an absolute minimum. The casino software at casino sites should be top notch and the game payout rates must be verified.

  • Signup process

    By law UK online casinos have strict requirements on verifying player data on signup and ensuring features such as deposit limits are easy to set for responsible gambling. Further, the best online casinos in the UK will have a clear and easy to use form which helps players sign up painlessly.

  • Payments

    Players want a variety of choices when it comes to payment options at casinos. We test the deposit and withdrawal options at online casinos from credit and debit cards through to e-wallets, bank transfers and online payments such as PayPal to make sure they are safe, fast, secure and easy to use. Casino payouts should never be a hassle when it comes to collecting your hard-won money.

  • Unique features

    The same old experience isn’t enough for a company to be classed as one of the best UK online casinos. We want to see new technology, competitions and interactive elements in a casino site which truly makes it a first-class experience.

  • Industry reputation

    Our team doesn’t confine themselves to just testing an online casino. We regularly reach out to our network of industry insiders, work on player forums and attend gambling events worldwide to get the inside story on the best casinos in the world today.

  • Security and support

    Thanks to the presence of former casino staff in house, we are able to engage with casino customer support on live chat, telephone and email to test their responses. We know the tough questions to ask which separate out the very best in the market when it comes to helping players.

  • Mobile experience

    More than 70% of online casino players in the UK use their mobile devices to play. With that in mind, the best online casinos will have fully responsive mobile web apps and dedicated apps for iOS and Android devices.

  • Licensing and legislation

    No site makes it into our top casino list if it does not have a valid UK Gambling Commission license and an independent complaint service available to players. This one thing should be the very minimum standard for any casino serving UK players and automatically excludes many worldwide sites.

Due to this rigorous process, any online casino site featured on our site will have met all of the above criteria and you can be sure it will be a great choice for even the most seasoned online casino player in the UK.

Meet Our Team of Online Casino Industry Experts

Our online casino team is a collection of casino players, gambling industry experts and former casino staff from gambling operators around the world. Our roster includes people who have worked with casino players first hand in customer support, VIP and high roller management programs, slot game testing and responsible gambling.

This allows us to present the best possible information at all times. Our reviewers use their real names so you can verify their credentials and experience and know that you are getting true expert advice on everything from live dealer play to the best bonus offers and everything in between.

Whilst the Gambling.com Group team has received many gaming industry accolades over the years, our proudest moment was when we were awarded the prestigious EGR Global (eGaming Review) award for our casino site in the UK. This was the only time in gaming history the awards were independently adjudicated and it shows that we are committed to bringing players the very best UK online casino sites.

Licensing and Legislation for Online Casinos in the UK

The UK government set up the UK Gambling Commission (UKGC) under the Gambling Act of 2005.

The UKGC regulates all commercial gambling in the UK which includes traditional arcades, sports betting (including telephone bets), bingo, pub fruit machines, slot machines, casinos and also the National Lottery games under the National Lottery Act from 1993.

As such, the UK Gambling Commission, under its remote gambling supervision, regulates all internet sites including all the best online casinos in the UK.

The license is regarded as one of the strictest in the world and is often used as a framework when a country changes its own regulations or implements legal gambling for the first time.

How Does the UK Gambling Commission Protect Players?

  • Fairness of gameplay:

    Online casino sites in the UK are only allowed by the Gambling Commission to offer games from game manufacturers that come from an approved list and have been independently tested by a company approved by the UKGC. At any given time, an online casino is required to hold a set amount of funds in reserve, like a bank, to ensure players will always be paid in full on winnings – including jackpots.

  • Personal data protection:

    All licensed online casinos in the UK must pass stringent tests to show that they protect casino player data, provide verifiable secure payment methods for deposit and withdrawal and that player funds and communication records are protected from outside access.

  • Responsible gambling and crime prevention:

    Strict checks must be in place at licensed UK casino sites following set procedures to identify and protect problem gamblers, minors and to prevent money laundering. Further, all UK online casinos must offer deposit limits and self-exclusion options for players that are easy to find and use.

  • Complaints and license enforcement:

    Every single online casino site in the UK is required by law to provide access to an independent body called an alternative dispute resolution (ADR) service. These agencies are approved by the UK Gambling Commission to deal with a customer complaint if the customer is not happy with the online casino’s own customer service.

    If any of the strict standards of the UKGC are not met by online casinos in the UK they have no hesitation in placing sanctions, fines and in some cases, revoking or suspending a casinos license.

We only include casino sites in our list which have an active UKGC license and provide links to that license so you can check it is valid. Never play at an online casino site which does not have a verifiable license in the UK.

Best UK Casino for Online Slots

The top online slots sites are often amongst the best casinos in general. However, there are a few things that make the best slot sites in the world stand out.

Best Blackjack Casinos in the UK

A great blackjack casino needs to cater for all varieties of the classic game with versions from as many different table game suppliers as possible, including live dealer options. There should be a wide range of stake limits per hand available and bespoke special editions such as blitz and jackpot blackjack if an online casino wants to be considered a leader in this category.

Best Live Dealer Casinos in the UK

Online Casinos in the UK Which Pay Out the Best

Rating the overall pay-outs on a casino is extremely difficult as it relies on the average RTP % of all their games and it can be hard to take into account which game types players prefer. Despite this, some casinos definitely do offer better pay-out percentages overall on average based on their games and this important information isn’t always available to casino players.

Online Casino FAQs

Statistically speaking, Blackjack technically has the best overall payout for a casino game as it has the lowest house edge at 1.5% if played to perfect strategy. This creates an RTP (return to player) percentage of 98.5% in the long term. That said, progressive jackpot slots offer the highest monetary rewards as they often run into the millions of pounds for a single win.

There are many great options for casino players. However, in the UK, the best casino game providers are often regarded as IGT, NetEnt, Microgaming and Novomatic as these have proven popular over an extended period of time.

Any casino in the UK which holds a valid license from the UK Gambling Commission should be regarded as a safe and secure site for UK players. All license holders must pass regular ad hoc inspections and meet the same standards.

In the UK we are lucky because every UKGC regulated and licensed casino site must meet technical safeguards that are set very high for player data. Also, casinos are required to hold player funds in a separate business account to the business funds to protect players against the casino failing.

Players can win huge amounts of money at online casinos if they get lucky. Fixed jackpot slots can often offer prizes of up to £250,000 and progressive jackpot slots have exceeded £10,000,000 on several occasions over the years. However, it’s important to remember that playing at an online casino is supposed to be a recreational hobby and you should carefully control your bankroll and avoid spending beyond your means at any time.
