2021 Review of the UK Gambling Market

The British are no strangers to online casino gambling, considering that the UK is the most regulated online gambling market globally. Many of the biggest operators are based or were founded in the UK.

The market is also characterized by stiff competition. New casinos are always appearing, each one promising one fantastic offering or the other. This can throw players off, especially when dabbling into online gambling for the first time.

That is why casino reviews are crucial for UK players. And a trusted reviewer like MontyPython is your best bet at navigating the bustling industry.

What Does Our Expert Guide Have to Offer?

As we mentioned previously, beginners often have a hard time navigating through online casino sites. This is due to a large number of operators available and the lack of adequate knowledge about gambling concepts.

Our reviews will break down these aspects by first filtering through and picking the best sites and then revealing to new players what pros and cons to expect. This way, players can avoid the risk of making wrong decisions.

Our reviews at MontyPython will also prove quite beneficial to the more seasoned lot. It won't be easy to try all these sites singlehandedly. However, our team of experts has personally and tirelessly tested these casinos. So you're guaranteed of getting a reliable second-hand experience upon which to base your decisions.

Our Search and Rating Process

To ensure that we take an unbiased approach to our reviews, we assess each site based on the same criteria. The major areas we consider are:

  • Gambling licenses
  • Fast registration process
  • User-friendliness
  • Safety and security measures
  • Competent and friendly customer service
  • Reasonable practices regarding responsible gambling
  • Bonus wagering conditions
  • Reliable game software
  • Diverse deposit methods
  • Fast payouts
  • Transparency
  • Real player feedback

Some of these criteria are what you probably already lookout for, while others you might not have taken into consideration previously. For instance, you may be keen on finding a site with an attractive bonus while overlooking customer support.

We, however, have acquired enough knowledge from experience to know that the latter can make or mar your gaming experience. That is why we don't just focus on one criterion but select those sites that offer the right combo of features. Keep reading as we take a more detailed look at some of the points listed above.


Our first point of call is to check whether or not an operator has a license. A license differentiates a reliable casino site from one that's potentially out to scam you. We don't just approve any license, though.

For UK casinos, the top regulatory body is the UK Gambling Commission (UKGC). The commission is responsible for regulating every online operator that caters to players in the region. In line with its rules, casinos have to abide by practices that ensure player protection, which is one of the major reasons for licensing. It is a guarantee that you are gaming in safe hands.

Besides the UKGC, there are a select few other licensing jurisdictions that have our vote of confidence. They include:

  • Malta
  • Curacao
  • Isle of Man
  • Alderney

To check that a casino is licensed, players can look for any of these licensors' logos. It is usually displayed at the site's footer.

Security Measures

Real money players have a lot at stake besides just the wagers placed. Opening a casino account requires you to disclose personal data like your name, age, email, address, etc. Your card or bank details are often saved on the site as well when you make deposits.

With all these under its care, a good casino should offer technical data protection, technical security, and malware protection protocols. The recommended standard is 128-bit or 256-bit SSL encryption which prevents unauthorized parties from accessing your details.

To further ensure that players are safe, the casino games RNG should be tested for fair play and randomness by a reputable independent auditor like eCOGRA. Players can verify this information on the site as well by searching for an SSL certificate and a seal of approval by eCOGRA. Strong security measures are often a consequence of adequate licensing.

Real Player Reviews and Website Reputation

The best online casino reviews are those given by real players who tried out the site. To complement the opinions of our experts who have personally played at these sites, we also consider other real players' experiences to determine how high our ratings should be.

Our experts visit casino forums to see what other players have to say about a site in order to achieve this. We evaluate the site's reputation, the impression it made on players, and the complaints laid against it if any. We also check how fast those complaints were handled or whether they are still pending. The best casino sites should leave you coming back for more, so we lean towards those with a positive reputation among players.

Deposit Methods

Banking options may not be on your list of thing to worry about if you play for fun. However, before you begin placing real money bets, you have to fund your player account. In our search to find the best online casinos, we always check the deposit methods available.

Different gambling sites offer different methods, but those available should be suitable for the particular region. For UK players, the top online casino deposit options are:

  • Visa
  • Mastercard
  • Maestro
  • Neteller
  • Paysafecard
  • Ecocard
  • Entropay
  • Neosurf
  • WebMoney
  • Wire Transfer
  • Boku

It is essential to provide solutions for a wide range of players, so the more options available, the better. By default, deposits are instant, especially when using card payment services like Visa and Mastercard.

Software Providers

For every casino review, we're ultimately testing out the games to get a feel of their features and how they play. Casino sites are only as good as their games. On the other hand, online casino games are only as good as their developers, and there is a handful of those that consistently release top notch quality every time. These manufacturers' games are in high demand at the best sites because players love them; we're talking about the likes of:

  • NetEnt
  • Microgaming
  • Play' n GO
  • Novomatic
  • Playtech
  • Yggdrasil
  • Big Time Gaming
  • Realtime Gaming (RTG)
  • International Game Technology (IGT)
  • Novomatic

A library with a collection of games by these developers is a good sign that games won't disappoint. NetEnt, for instance, is known for innovative game features and HD graphics. Playtech games are characterized by high payout rates, while Microgaming has a catalogue with dozens of branded titles.

Qualified Customer Support

Customer support may not be the first thing you'll look for in a gambling site, but you'll hardly ever end your casino online adventure without needing customer service. Our experts put the support team to the test by asking tough questions to see how they respond. Quality customer support should be fast and efficient in providing useful information. Also, the range of contact options should include:

Telephone – toll-free call lines will enable players to call in from different locations at no cost

Email – this is great for enquiries that are not too urgent

24/7 Live Chat – with round the clock support, there is always a casino representative ready to lend a hand.

Responsible Gaming Practices

Gambling online is considered a vice by conservative groups because it can be addictive. In order to combat this stereotype, we make it a priority to evaluate the responsible gaming practices at any site we review. The best casino sites will offer one or more of these checks:

Self-exclusion/timeout limit – To give yourself a break from gambling for a short while.

Deposit limits – To restrict the amount you can pay into your account on a monthly, weekly or daily basis.

Account tracker – To monitor your gambling record, including hours spent playing, wins and losses.

Reality check – A pop-up window that reminds you when it’s time to take a break or call it quits for the day.

Permanent account closure – To shut down your account.

Besides, several organizations exist to help UK players fight gambling addiction, most notably Gamcare and BeGambleAware. Sites that advocate responsible gambling will help players with problem gambling signs to get in touch with these non-profit agencies.

Casino Bonuses and Wagering Conditions

Welcome bonus – A bonus offer made available to new players after making the first deposit.

Deposit bonus – A reward that matches your deposit to a certain percentage.

No deposit bonus – An offer made available to new players as a reward for signing up, with no deposit required

Free spins – A casino offer that lets you spin the reels for free on selected slot games.

Although there isn’t a casino rulebook that indicates bonuses as a compulsory feature, it’s impossible to imagine a site without bonus offers. Large bonus amounts are undoubtedly eye-catching, but that’s not all there is to these rewards. There are bonus terms and conditions to keep in mind, most especially the wagering requirements to be rollover before you can withdraw your winnings. The most generous offers should be crystal clear and transparent conditions with no hidden clauses.

Types of Online Casinos

The variety evident in the game collection, bonuses, and other casino features is also applicable to the casino platform itself. There are multiple types of casinos based on the unique features they offer. While some sites are notable for their fast payout speed, others may excel in providing an instant play platform.

With the new technological solutions available, some sites adopting the no registration process are categorized as "no account casinos." We'll elaborate on the individual attributes of these different casinos below.

Real Money Casinos

The UK gambling market is predominantly occupied by real money casinos. The name suggests that these sites offer real money gaming opportunities, and players can benefit from numerous perks when playing on these platforms.

Firstly, these sites allow you to place real bets and win cash on successful rounds. Bonuses are only claimable for real money, and when playing at a slots casino, you stand a chance to hit life-changing prizes on the progressive jackpot slots available.

Fast Payout Casinos

These sites cater to one of the most pertinent worries shared by players – payout speed. Gambling withdrawals are often long and cumbersome due to verification processes. Operators need to verify players' identities before accepting withdrawal requests. Sometimes, you may be asked to provide additional documentation for further verification. Although this is in line with KYC (Know Your Customer) protocols, the wait may seem to go on forever.

With fast payout casinos, the processing time is reduced significantly. Although withdrawals still aren't as immediate as deposits, they are certainly much quicker than standard casinos.

No Download Casinos

The salient feature at these sites is instant-play gaming, which eliminates the need to download casino game software. Using HTML 5 technology (the Hypertext language that supports mobile and desktop compatibility), no download casinos allow you to access games and other offerings directly on the website. You simply have to log in through your web browser and press the play button on your preferred game to start playing.

No Account Casinos

No account casinos are online gambling sites that eliminate the registration process applicable at regular casinos. This feature is powered by Trustly's Pay 'N Play platform, which carries out player verification through online banking. By depositing at the site, Pay' N Play confirms and registers your identity through your financial service provider.

The primary goal is to allow you to begin playing without the delay of signing up. Other benefits include increased security and speedy withdrawal times.

Free Online Casinos

As opposed to playing real money games, free online sites allow you to play as many titles as you wish for free. As you can imagine, with free games, you can't win cash returns since you don't actually place bets. But besides that, these games are identical to their real money versions in features and gameplay.

So, if you're looking to enjoy carefree spins on the slot machine or to test run a few rounds at the blackjack table, you won't notice a difference.

The UK Live Casino

The live casino replicates the traditional land-based experience while still allowing the convenience of gambling online. UK players can play from the comfort of their homes, as the live dealer games are broadcast from physical gaming studios within and around the UK. It's no doubt a unique experience, and luckily many operators are incorporating a live dealer section on their sites, alongside regular software-based options. 

A few software providers like NetEnt, Microgaming and Ezugi offer live dealer table games. However, Evolution Gaming is the industry leader with several player favourites under its belt, including:

  • Live Blackjack
  • Speed Roulette
  • Monopoly Live
  • Live Dreamcatcher

Mobile Casino

Playing at a mobile casino means you get to enjoy your favourite online slots, blackjack, roulette, poker, other table games, and live dealer variants on your portable devices. This is the trend nowadays. As the industry is not known to lag behind innovation, the best casinos online will offer mobile compatible options for players. Mobile apps are also available to support a range of devices with a focus on Android smartphones, Tablets, iPhones, and iPads. 

With mobile gaming, players can expect superb graphics and a seamless interface. Bonuses and other perks are available too, and you get all these features in a compact platform that you can take on the go.
