Understanding the UK online casino industry

Online casinos in the United Kingdom are fully regulated and 100% legal. The industry is estimated to be worth well over the billion-pound mark annually and has a huge base of regular players.

The World Gambling List wholeheartedly endorses playing at casinos regulated by the United Kingdom Gambling Commission, or another respected jurisdiction based in a territory governed by the Queen, such as Gibraltar or the Isle of Man.

While slots are the biggest revenue generator for online casinos, other popular games include poker, blackjack, roulette and, increasingly, games of skill and virtual sports.

Best online casinos in the UK

British citizens do not have to look far to find an online casino, with many of the biggest and best advertising regularly on free-to-air and pay TV. These include global giants such as 32Red and bookmakers who have ventured into lucrative casino wagering, such as Bet365 and William Hill.

Some of the more important things to look out for when choosing which casino to play at from the UK include where they are licensed, whether they support Great Britain Pounds (Sterling), what software the casino uses, customer service and, of course, the website’s reputation.

It pays to do your homework on an online casino at independent review websites such as this one, although many are run by people trying to steer traffic to their own casino (if only WGL could afford its own casino).

Top 10 UK online casinos

In this section we present our top 10 online casinos list in the United Kingdom:

Temple Nile Casino: A popular online casino that has got a strong selection of real money games. Temple Nile Casino has both live dealer and slots and provides a strong digital gambling service right across the board. While Temple Nile is not as well know as some of the top online casinos, we have faith they are up to scratch. Temple Nile review.

William Hill: More known for their sports betting platform, William Hill Casino is powered by Playtech and is one of the top casinos online powered by this software. Hills has got a strong live casino, on top of their selection of popular slots. Hills also has some entertaining casual games, that give them a point of different to other casinos. William Hill Casino review.

Guts.com: A casino that burst onto the UK gambling scene as one of the first that had multiple software providers. Guts Casino has changed hands several times over the years, but has always maintained a high standard. With Nordic roots, Guts.com does lack a UK casino sign up bonus, but they do tend to have a low RTP rate.

MansionCasino: A highly-respected gambling brand in the United Kingdom and beyond, Mansion Casino has got over 2000 games including 100s of real money slots. Mansion Casino is comfortably among the best online casinos in the UK, with its multi-language support and bevy of payment options just two of its highlights. Mansion Casino review.

Casino welcome bonuses

This is when an online casino gives you something for opening your account. Often it will come in the form of a matched deposit. For instance, you might deposit $100 and receive a 100% match up to the value of $100. Meaning you will have a total of $200 to bet with. All of the best online casinos will have a welcome package available to new players.

Free spins at UK casinos

Free spins are redeemed on the slots and most online casinos have ongoing promotions surrounding these games. Many UK casinos will give new players 100 free spins over the first five days they have their account, as a way of getting the customer to come back and play again after the initial deposit. In the UK, legislation makes casinos call them bonus spins, or extra spins, rather than the “deceptive” free spins. On top of free spins sometimes being a part of online casino sign up bonus offers, they can often be acquired through other ongoing promotions.

No-deposit casino bonuses

As it sounds, the no-deposit casino bonus is when the casino gives you some cash to try out the games. Often the wagering requirements will be unrealistic on this type of bonus, but they can be a great way to get the vibe of the casino before depositing real money. Be aware, many casinos online will have a no deposit bonus available, but it will be net to impossible to profit from it. You could also say some free spins deals are no deposit bonuses, with it just a matter of creating a new casino account to receive the offer.

Casino cash back deals

Cash back offers at online casinos usually taking the form of a percentage of your losses. Cash back offers can be great for VIP players at online casinos. A 2 or 5 per cent cash back scheme with low wagering requirements can be worth a lot more to a whale than a few hundred bonus when they sign up. Usually cash back schemes will be part of a VIP scheme, set up by many of the top UK casinos.

Casino VIP memberships:

These can be very beneficial and many online casinos run them. They can include things such as lower wagering requirements on bonuses, exclusive bonuses, free cashouts, cash back offers and your very own dedicated VIP customer service member. Many of the best online casinos will offer VIP memberships to players they deem to be high value.

Free credits or game credits

Some gambling companies in the UK have changed how they offer bonuses, as a way of being more responsible. These companies, like bet365, instead offer credits as their bonus, that can be wagered and then converted to real money or prizes.

Online casino bonus offers are evolving all the time! The good news for UK casino players is there are 100s of casinos with sign up and retentions promotions running. The World Gambling List vets and uses all the UK casino bonus offers before advertising them.


Best UK mobile casinos in 2021

Online casinos have invested heavily in the development of mobile games. Unlike most of the world, the UK has many real money apps readily available from the Apple App and Google Play stores.

This doesn’t mean you must download an app to play at an mobile casino. You can simply visit their mobile website and play instant-play games, while even making a web app for quick access.

The casino games and deposit selection at mobile casinos will not be as great as on a PC or Mac, but you will find there are enough games and it’s improving all the time.

For instance all of the major casino games companies that operate in the UK work on a mobile first philosophy. This means, before developing desktop games they are first planned out on mobile, making sure that they function perfectly on everything from smartphones to tablets.

One of the most popular ways to play at mobile casinos in the United Kingdom is via downloadable apps, which can be broken into two different types: iOS and Android. Casino apps are legal in Great Britain and tend to make mobile play more fluent, including faster game loading times and a great selection of titles.

Some of the United Kingdom’s best mobile casinos include brands like William Hill and bet365, that have cut their teeth as sports betting sites, before moving into online gambling.

Best casino apps for the United Kingdom

The top UK casino apps are available to download on both iOS and Android smartphones, with these the two main operating systems used all over the world. Casino apps are essentially small software downloads that give you features and accessibility that you won’t find available at mobile casinos.

Android casino apps

Android is probably the top operating system for real money casino apps in 2021, with this operating system giving you a lot more freedom than Apple products. By this, we mean that you will find some casinos have apps available for Android, but will not on Apple phones. The big benefit of Android casino apps is that you can download non-market apps, meaning they come straight from the gambling site, instead of through the Google Play store.

iOS casino apps

The best iOS or Apple casino apps are available to download directly from the Apple App store and give you access to extra features that you might not find at the mobile casino. The World Gambling List UK recommends creating a new casino account prior to downloading a brands iOS casino app, largely because you might not get all the promotions up for grabs downloading it directly from Apple.


Free play online casinos

Free play online casinos are ones that allow you to play their games without making a real money deposit. There are some casinos that operate just as a free service, while others will put a time limit on you or give you a certain amount of play credits before insisting you make a real money deposit.

Free play casinos in the UK include some of the biggest brands in the world, with William Hill and 888 Casino leading the way in this regard. After you have created an account you can play various games for free, although it’s important to note that online slots and RNG tables games are the main games that are free.

Other UK casino games like live dealer is very unlikely to be found in free play mode, with this because of the extra overheads and staff associated with running these games. Other games like slots and RNG table games are free because they are essentially just software, that doesn’t require on call staff to play.


Deposit & withdrawals at British casinos

Because the UK is a fully regulated gambling environment it means there are minimal issues with deposits and withdrawals when you are playing at an online casino based in its jurisdiction.

All in all, you should be able to be playing with real money at an online casino within five minutes of signing up. As a general rule you visit the banking or cashier section of the casino to begin making a deposit.

You then select what type of deposit you wish to make, with credit and debit cards and bank transfers among the more common methods. At the time of writing, 32Red had more than 10 deposit methods available for UK residents.

As a general rule UK casino withdrawal options will be less in number, but it’s still a simple experience and should be completed within a few days. There are instant withdrawal methods available in the UK, but again it will depend on several factors like how you made you initial deposit and whether you have a web wallet like Neteller.

Popular deposit methods:

  • Visa: Visa and other credit and debit cards, including their prepaid versions, are the No.1 deposit method at online casinos.

  • Wire transfers: This is a traditional deposit method, where you transfer money from your bank account to an account held by the casino. If you are in the UK this should be facilitated overnight if you are playing at a casino regulated in the UK.
  • Ukash: This option is accepted at most gambling sites. You can buy Ukash vouchers at various shops in the UK and online.
  • Boku: An SMS deposit method at UK casinos, Boku casinos have sprung up at a rapid rate in recent times, Essentially allows you to fund your gambling account with your phone bill.
  • PaySafeCard: A deposit option allowing you to deposit money at casinos. Works much like Ukash in that you buy the card from a retail shop.

  • EcoPayz: A popular web wallet that works by linking a credit or debit card to your account.
  • Skrill: Formerly known as Moneybookers, Skrill is a web wallet which allows you to instantly fund your online casino account.
  • Neteller: Another popular web wallet solution, it works by linking a credit or debit card to your account. A real plus of Neteller is you can withdraw back to your account almost instantly.

Withdrawals usually take about a day to be processed and a further day to be finalised in the financial system. While you can withdraw to web wallets, the most popular ways are a bank transfer and a cheque sent out in the mail.


British casino games 2021

As one of the better licensing jurisdictions there are few casino games not available. UK Online slots are the most popular casino game for UK players, as well as many poker variants.

One of the better parts of UK online casino games is that they serve high rollers and people with smaller bet limits equally as well. There is no discrimination if you are spending just a few quid a spin on a roulette wheel, just like online casinos won’t steer clear if you are wagering £10,000 each spin.

Online casino games work equally well across multiple mediums, including mobile, desktop computer, laptops, smartphones and even smart TVs. Basically, if you have an internet connection and web browser you will be able to play casino games.

Online Slots: Often called puggy machines in the UK, online slots are popular right across the country. Some of the more popular software developers for slots are Microgaming, Playtech and Betsoft. UK casinos undoubtedly have an outstanding array of casino games in comparison to other gambling jurisdictions.

Online Blackjack: Online casinos will have various versions of 21 available, including live dealer games. Other blackjack will include RNG titles, which are basically computer generated tables, that allow you to play both high stakes and lower limit or social blackjack

Online Roulette: Much like blackjack, roulette is one of the more popular games available. You will find it with live croupiers and in RNG form at casinos licensed in the UK. You will even find online casinos that have live streams of roulette tables from some fo the most famous casinos in the country and Europe.

Online Poker: While you can play Texas Hold’em at poker sites such as PokerStars and Full Tilt poker, the versions you will find at online casinos are played against the dealer. Casino Hold’em, Caribbean Stud, 5 Card Stud and 5 Card Draw are just some of the variants you will find.

Online Baccarat: While not insanely popular at online casinos in the UK it does have a steadfast fan club. You will find games with huge bet limits. Baccarat is exceptionally popular in Asia, largely because it is considered the game of high rollers, because of it’s low house edge.

Housie: Known as Bingo in some quarters, UK punters are smitten with this game. We’ll do further articles on this in the future, but for now rest assured it’s available at online casinos. Online bingo can be played at both casinos, or at dedicated House sites, which will have a much bigger variety, including community games.

Lotto: The face of lotto has changed forever; it is now possible to play a live game of lotto at online casinos. Basically you pick your numbers and every few minutes they have a draw. Keno is also growing in popularity at online casinos.

Virtual casino games: Various sports and other events have been made into animated games that give you odds and allow you to wager real money on them. Virtual casino games include things like 3D table games and horse racing simulations. Virtual games are expected to be a big growth area at online casinos as 5G is rolled out across the world.

Basically if there is a game you have seen at a land-based casino you will find it at the online equivalent. Much will depend on what software the online casino uses. For instance, UK casino players have a much greater selection of games than in countries like Australia, which has banned online gambling.


UK casino software

United Kingdom online casinos use an abundance of different software to power their games and operations. What iGaming software the casino uses will largely come down to what platform they use, with many of them allowing operators to mix and match their games offering from a variety of providers. 

Some of the more popular online casino software that is used in the UK includes industry giants like Playtech, Microgaming, Net Ent and Scientific Games, with all of these companies having huge footprints right across the world and boasting licenses from the Gambling Commission. 

Some UK casino software companies will specialise in online slots, while others have more of a reliance on live dealer or skill games. Basically, each casino software company will have its thing going on. The World Gambling List has written hundreds of articles about the different games and offerings provided by casino software companies.

UK online casino laws

The biggest and arguably the most respected licensing body is the United Kingdom Gambling Commission. This body also oversees all land-based gambling, including betting shops and casinos.

From an online casino’s perspective it must have a remote gambling license, issued by the UKGC, if it has any part of its operations based in British waters, or ‘transacts’ with or advertises to punters based in the UK.

The gambling commission places conditions on online casinos operating in the UK, and has a code of practice which outlines things such as not targeting minors or people in a disadvantaged climate, and also offers assistance to those who may be deemed ‘problem gamblers’.

The United Kingdom Gambling Commission, on September 5, 2018, announced it was calling for for feedback on proposed changes to gambling operators rules surrounding age verification checks and other perceived pitfalls of running a safe and fair website.

The other two licensing bodies that fall under British rule are Gibraltar and the Isle of Man, which both place similar high standards on casinos issued with their licence.

The Isle of Man, one of the pioneers of online wagering regulation in 2001, uses e-gaming as a way to prop up a shaky economy, with many casinos and sports betting sites basing themselves in this British dependent territory. You will often see officials from IOM promoting their country at e-gaming conferences around the world.

Gibraltar is another respected jurisdiction, although not as popular as the IOM, with brands such as Ladbrokes and casino software developer NetEnt holding licences with this body.


VIP programs at UK casino sites

The UK has one of the most developed online gambling industries in the world, with most online casinos having extensive VIP programs.

VIP programs give players added perks, which allow them to receive things like exclusive bonuses, dedicated account managers and cash back deals, plus many more things.

At the beginning of 2020 a report has emerged via the Guardian newspaper, which has shed a light on just how important VIP programs are to the gambling industry.

The report shows one operator made up 83% of of all its deposits from just 2% of the total deposits, while 5% of another casinos’ patronage made up 58% of its deposits.

The report on VIP programs in the Guardian pointed to the high total of VIP deposits, but it failed to mention that the percentage of VIP deposits was not losses, rather how much has been deposited.


Timeline of major events in UK online casinos

September 2020: The global covid-19 pandemic has also impacted the UK casino industry, although for online casinos it has proven to be a windfall with lockdowns and peoples reluctance to go to retail venues proving decisive. The Gambling Commission ha also been strong in its messaging to both online casino operators and their affiliates, that they must act responsibly throughout the pandemic, and not attempt to cash in on the situation. 

January, 2020: The Gambling Commission is reporting that online casinos were searched for more than ever before, indicating that online gambling has grown significantly in the United Kingdom, even before covid-19.

November, 2019: Shares plummeted in UK online gambling companies as MPs from the cross-party group on gambling related harm told parliament that online slots should be subject to the same restrictions placed on fixed-odds betting terminals, which is currently set at £2 per spin. Estimates are that the change will cost gambling companies £1.2bn. Sources at UK online casinos have told the World Gambling List that they fear it will force punters to play with offshore online casinos, where no such restrictions will apply.
