How to know if a UK casino is safe

If you’re playing at a UK casino that is licenced by the UK Gambling Commission, you can be sure that it’s safe to play at. At JohnSlots, we take great care to recommend only licensed and safe casinos. Over and above the licence, you can check that the casino has SSL encryption and verified games. Let’s have a look at the UK licence in more detail and how it protects UK players:

UK Gambling Commission

The UK Gambling Commission has been around since 2007… though when it comes to online casinos, no one really gave it much thought until late 2014. Basically, the UKGC is the regulatory division of the UK government that oversees all gambling activity of UK players. They’re not just setting rules and taking taxes – they’re in place to protect people from the possible dangers of gambling like addiction, underage gambling and money laundering.

Although UK casinos have had to make many changes to their process since the introduction of the UKGC, it’s all for the better. They promote responsible gambling in a safe environment and ensure you’re never playing outside of your means. Here’s how things have changed over time:

Timeline of the UKGC

  • 7 September 2007: The UK Gambling Commission is formed as part of the Gambling Act 2005
  • 1 October 2011: The National Lottery Commission becomes part of the Gambling Commission
  • 1 October 2014: New regulations mean that offshore online casino operators wanting to accept UK players must obtain a UK licence from the UKGC
  • 31 March 2015: Another new rule is brought in to enforce UK-licenced online casino operator to only offer games from UK-licenced game developers
  • 29 June 2017: The UKGC cracks down on problem gambling and now requires online casinos to provide players with tools to monitor their wagering activity
  • 31 October 2018: The UKGC sets new standards for dealing with customer complaints
  • 7 May 2019: Online casino operators are now required to complete KYC (Know Your Customer) checks before allowing their players to gamble
  • 14 April 2020: UKGC introduces a credit card ban which means that UK players are no longer able to gamble using their credit card at UK casinos.


Online casino UK sites


To hold a UK licence means that the casino has gone through strict tests and processes set by the UK Gambling Commission, and that the UKGC have verified their legitimacy as an online casino.

It’s not a simple process, and to obtain the licence an online casino operator needs to prove that they promote responsible gambling and don’t allow players to wager more than their means; that they don’t accept underage gamblers; and many other important factors. This is why a UK-licensed casino is considered to be so safe and trustworthy, and not just any casino is granted a UK licence.

Once obtained, the UK licence is not guaranteed for life, and online casinos that fail to follow to follow the regulator’s rules are at high risk for losing their licence. Hefty fines on profits made from players can also apply, along with stricter punishments for negligence.

If you find a casino that allows UK players but doesn’t hold a UK licence, it could mean one of two things: they either had a licence but lost it, or they never qualified for one in the first place. You should avoid playing at non-licenced casinos at all costs, since the Gambling Commission can not verify their safety.

Recent online casino regulation in the UK

With the possibility of Brexit on the horizon, it’s hard to say what will happen to gambling in the UK. Some people say since the UK already operates separately to the rest of the EU, the impact will be minimal… but some experts suggest that UK regulations could become even stricter.

The one thing we can all agree on is that the UK licence will continue to exist and serve its players. Perhaps companies will no longer be able to operate from offshore countries, but only time will tell. We can, however, tell you with absolute certainty that we’ll always keep you updated, and continue to only bring you casinos that are 100% safe to play at.

Casino bonuses, free spins, bonus spins and other promotions

Look for the best UK casino offers

We’re always on the lookout for the best UK casino offers, so you can find them easily, all in one place. Here are some of the best offers exclusive to the UK to keep your eyes peeled for:

  • Free spins: This is a great offer to receive, either as a new player or an existing one. Free spins give you free chances to win, but without the wagering requirements, so you’ll often get to keep any wins incurred from the spins.
  • Bonus spins: Kind of similar to free spins, bonus spins give you ‘free’ chances to win on a slot – but any wins will need to be wagered to satisfy requirements before you can make a withdrawal. We’ll always tell you the terms and conditions for these offers, so you can make sure you’re playing with the lowest wagering requirements at a casino UK
  • Promos: The fun doesn’t stop once you’ve taken your welcome offer, and many UK casinos offer regular promotions for existing players to keep them coming back. At JohnSlots we do a weekly round up of the top UK promos for the week, so you can find them all in one place.

When playing with UK casino offers, make sure to always read the terms and conditions to check you’re getting the best offer possible. Many promotions and offers will have wagering requirements tied to them, which is totally standard but also super important.

Get to know UK casinos even better

Along with bringing you news, new UK casinos and new games, the JohnSlots team is also here to answer any and all of your UK casino-related questions. Here’s a look at the most frequently asked questions and their answers.

Can I play in casinos without a UK gambling licence?

You might be able to, but we really recommend that you don’t. You won’t find non-licensed casinos here at JohnSlots anyway, but if you happened to find one online it’s highly likely that it will be shut down soon. It’s also not safe or legal to play at a casino without a UK gambling licence since their legitimacy hasn’t been verified.

Are my online casino winnings in the UK tax-free?

For now, all your online casino winnings in the UK are indeed tax-free. Happy days!

Is it legal to play in online casinos in the UK?

As long as the online casino operator holds UK licence, it is 100% legal to play, provided you’re 18 years or older and you do not make payments using your credit card. It is your responsibility to ensure you are playing legally online so do make sure you meet any legal requirements before playing for real money.

Are there any exclusive offers for UK casino players?

Absolutely, and often UK casino players are given a different offer from the rest of Europe. Make sure to check out the offers above to see what’s currently on offer.

Can I trust the payout percentages at a UK casino?

As part of the regulation, UK casinos must be upfront about their payout percentages across all games. So yes, you can trust the payout percentages.

What is the KYC check?

KYC (Know Your Customer) is a process that UK casinos must complete before you can begin playing. It involves checking you are who you say you are, along with where you’ve received your money from. It may seem a bit boring to do, but it’s extremely important in preventing anti-money laundering and problem gambling.

What documents do UK casinos request?

This can vary from casino to casino, but generally, UK casinos will ask for identifying documents such as a copy of your passport, bank card and utility bills with your name and address on them. To prove your source of funds, you may also need to provide bank statements, invoices or similar documents.
