Our Guide to Playing at UK Online Casinos

The team of experts at VegasSlotsOnline has compiled helpful tips and tricks for joining and playing at the top UK online casinos. Look no further than our comprehensive guide to online UK casino gaming for the latest information:

Safety and Security Measures 

Any details you supply to a UK online casino, including bank details, are confidential and are securely encrypted to protect against hacking. It is your responsibility to ensure that any details you provide are accurate, and anyone providing false information could have winnings withheld and even face prosecution.

To ensure your own safety, the UK Gambling Commission provides information on what to look out for. The first thing to do is check that the operator is fully licensed by the Commission. Licensed operators must also provide information on how to gamble safely. Under UK Gambling Commission rules and UK online gambling laws, players' funds are segregated from operating costs. This safeguards the player in the case of fraud or liquidation. It's not a uniform practice across all gambling jurisdictions.

A robust complaints procedure and measures to protect young and vulnerable people should also be in place. At online casinos, UK customers must be given information on gambling responsibly and be supplied with tools to help customers control their betting.

Finally, the Gambling Commission supplies an Alternate Dispute Resolution (ADR) provider in the case of any serious disagreements between the customer and the website.

In 2018, a new ruling on online casino UK bonuses was made. The Competition and Markets Authority (CMA) is cracking down on online gambling companies who make vague promotion promises. It may also become easier for gamblers to clear deposit bonuses. 

The bottom line is: when you are gambling online in the UK, the country has strict measures in place to protect you, your money, and your data. Just ensure you’re signing up to an online casino that’s licensed by the UK Gambling Commission.

Top-Quality Bonuses and Promotions 

For players, especially those who are new, UK online casinos offer plenty of bonuses and promotions. UK online casino bonuses come in many shapes and sizes, but you’ll find a few common ones as you peruse our list of the best UK online gambling sites.

No Deposit Bonuses

At UK online casinos, no deposit bonus offers are quite common. The online casino will reward you just for signing up, even before you make a deposit. Think of is as a “thank you” for joining the operator’s site. These bonuses typically come in small amounts, often between 5 GBP and 20 GBP. You can use the funds to play at any of the games on the site. It’s a great way to kickstart your UK online casino experience. 

Free Spins

Often paired with no deposit promotions, free spins bonuses give you a few free spins on the online casino’s slot games. The amount varies; some offers will give you five free spins while others will grant you 20 or more. If you win using the free spins, that’s extra money in your account. 

Look out for great combination offers at the best UK online casinos. Some sites will give you a no deposit bonus plus a number of free spins, maximizing your account value before you even start playing!


Word of mouth can be a powerful marketing tool for online casinos. Some UK online gambling sites even encourage it directly with refer-a-friend bonuses. The structure of these bonuses varies by casino, but they usually use a similar formula. You share your unique link or code for the online casino with a friend. Once the friend signs up and makes a deposit, you each get a credit to your account. Check the terms and conditions for the exact reward amount, as some online UK casinos offer more lucrative referral bonuses than others. 

Match Bonus

Make a deposit; watch your money double. That’s how simple deposit match bonuses can be at the best UK online casinos. Match bonus offers are often capped at a certain amount, and that changes from casino to casino. At the higher end, you may find a match on your first deposit up to 300 GBP. If you’re especially lucky, some online casinos offer the bonus on your first two deposits, really amping up the benefit. 

Popular Casino Games for UK Players

At most online casinos, UK-based players have a choice of hundreds of top games. Gamblers can pick from classic slots or the latest 3D animated brand tie-ins. There are also dozens of progressive jackpot games with the potential to win six and seven-figure prizes. As we've mentioned, unlicensed games are generally NOT available at UK-facing online casinos.

According to Gambling Commission stats for 2016-17, UK online casino betting accounted for nearly half of all remote gaming in the country. Far and away, online slots accounted for most of the casinos' turnover, with table games a distant second. 

Typically at online casinos, UK gamblers can access many games not found in land-based casinos. Variants like American and French Roulette, Craps, and Caribbean Hold'em are not common to the smaller UK offline casinos. The minimum stakes at UK online casinos are generally a lot smaller than those found in land-based casinos.

In addition to the hundreds of slot games and niche table games you’ll find on our list of the best UK online casinos, you can also play various popular table games like Blackjack, Baccarat, and more. 

Thanks to the country’s friendly online gambling laws, UK players have a wealth of riches when it comes to online casino game variety.

UK-Friendly Casino Deposit Methods

When they play at the best online casinos, UK players have a broad range of gambling banking options on hand. Licensed real money online casinos easily accept payments via debit cards, plus a good spread of e-Wallets and prepaid vouchers. Bank transfers offer a secure way of moving cash to and from a casino site. The only payment method online UK casino players may be surprised to find unavailable is credit cards.

To receive an online gambling license, UK sites must have the right security in place to protect transactions. Transfers of cash should be encrypted and player funds - by the rules of the UK license - should be segregated from operating costs.

To deposit at casinos online, UK players can transfer in GBP, though most good casinos also offer USD and EUR as standard.

Debit Cards

UK bank debit cards like Maestro, VISA Electron, and Solo are perfect ways online gambling UK enthusiasts to get their casino funds in and out. As long as the online casino is properly licensed, players shouldn't have issues moving real money to a casino account using a debit card.

The beauty of debit cards is that they generally carry low minimum limits and no fees. And UK online casino customers can enjoy their bank's trusted encryption when sending money across the web.

Prepaid Cards and Vouchers

If you’d rather not use your debit card, most UK online gambling sites accept prepaid cards or vouchers. They’re a simple, effective way to fund your UK online casino account. You can purchase a card for a specific amount, then use it to deposit funds into your account. 


e-Wallets have been accepting UK online casino payments since their inception. Leading e-Wallet operators like PayPal, Skrill, and Neteller allow anonymous and safe transactions via a third-party processor. Payments are instant, and online casinos generally won't charge a fee on your deposit. However, the e-Wallets will charge a fee if sending cash back to a bank account or overseas.

UK Casino Gambling Laws in 2021 

In the UK, the casino industry is regulated by the UK Gambling Commission, which is part of the government Department for Culture, Media and Sport. It was established under the Gambling Act 2005 by the then-Labour government. 

The Gambling Act of 2005 was introduced to control and regulate all forms of gambling, including online casinos, in the UK. It sought to bring up to date the country's rather outdated gambling legislation. It also aimed to deal with the evolution of new UK online gaming sites that were beginning to appear.

A new Gambling Commission was set up at the same time as the regulatory body, to issue licenses to online betting companies and monitor their compliance with relevant laws. This was the first time remote operators had been subject to regulations in the United Kingdom.

Figures from the commission show that from April 2013 to March 2014 the British gambling industry (excluding the National Lottery) generated a gross yield of £6.8bn, an increase of 6% on the previous year. The remote betting sector (including slots and online casinos in the UK) accounted for 17% of the revenue during that period and has increased in value for each of the last five years that the commission has published figures.

The total gross gambling yield (GGY) of the Great Britain gambling industry between April 2016 and March 2017 was £13.8bn. But despite the new licensing laws, online gambling in the UK rose 10% to £4.7bn from 2016-17.

The UK government had introduced the Gambling (Licensing and Advertising) Act in 2014. In day-to-day terms, online casino UK players aren't affected. However, it does mean that any casino or software provider wanting to supply the UK must have a UK Gambling Commission license. This comes in addition to any existing license a provider may hold overseas.

Land-based Gambling Options in the UK 

The UK boasts 146 land-based casinos, and the Rank Group (Grosvenor Casinos) is easily the largest chain in operation. Genting UK and smaller operators like Aspers also offer an increasingly Vegas-style gambling experience. Membership is not always needed at UK offline casinos, and the days of 48-hour membership waits are long gone. As with online casinos, UK players in land-based establishments tend to slot machines including large-payout Vegas-style terminals. Electronic roulette is also popular, as are table roulette and punto banco.

While England, Wales and Scotland all feature a spread of casinos, land-based casinos are still outlawed in Northern Ireland.

Away from casinos, offline and online bingo remains popular. Many established chains run land-based bingo halls up and down the country. Some have migrated to UK online betting sites of their own. Internet slots can be played at most online bingo rooms too. It is currently legal to play slot machines (fruit machines) in pubs, clubs, and amusement arcades with adult supervision. As of 2017, there are just over 182,000 physical gaming machines in the UK.

Though controversial, UK gamblers can access popular casino games and slots via Fixed Odds Betting Terminals (FOBTs) in high street bookmakers across the country. There has been a hard campaign to limit the maximum stakes available on FOBTs. However, for casual gamblers they provide a quick and easy way to enjoy a spin of roulette or slots machines without entering a casino.

Taxes on Gambling Winnings in the UK 

After a change in law under the Labour government of Tony Blair, duty on betting winnings was scrapped. Likewise with online casinos, UK residents are subject to no tax on their prizes. The UK doesn't operate a windfall tax on large lottery wins, either, as in some other countries.

However, in some circumstances, gambling winnings may be subject to tax if gambling provides the main source of income. HM Revenue & Customs (HMRC) has a more detailed breakdown of how personal income is taxed in the United Kingdom.

Brief History of the UK’s Gambling Industry

1640s - Britain's first gaming room, Whites, opens and offers table games to visitors.

1700s - Legalised lotteries are introduced to pay for public projects like the British Library.

1820s - London's Crockfords club opens and provides dice games and other table gambling for the city's elite.

1845 - The Gaming Act of 1845 is passed. It's the government's first major law that deals with the problem of gambling debts. A form of the law would stay on the UK statute books for a further 150 years.

1906 - In a crackdown on illegal betting shops, the Street Betting Act is passed.

1960 - The Betting and Gaming Act 1960 legalises high street bookmaking. The laws are tightened with the Gaming Act 1968. Bingo halls and members' clubs are licensed and allowed to provide fruit machines and small-stakes gambling. Plans for 50 new casinos are drawn up, although they can only operate with strict membership rules.

1994 - The UK's first legal National Lottery is drawn.

2005 - The Gambling Act 2005 leads to the setting up of the Gambling Commission and the country's first real framework for dealing with online casinos and gambling sites. Although later scrapped, plans are made for a range of new "super casinos" to be built in the UK. By 2017, only three have been built. Laws on live poker are also relaxed. It becomes legal to play small-stakes poker in pubs.

2014 - The Gambling (Licensing and Advertising) Act 2014 is brought in. It gives the Gambling Commission the powers to issue licenses to overseas developers and casinos offering games to UK residents. In addition, a 15% levy must be paid on any activity specifically targeting UK gamblers.

2020 – House of Lords committee pushes UK government to revise gambling regulations.
