Understanding Online Casino Laws

If you're thinking about playing at a UK casino online, you should understand the laws around them before getting started. As an online legal casino operator, there are a bunch of rules and regulations in place to protect British gamblers that want to play real cash in a lawful manner.

There's a lot to remember as a casino operator, but if you just want to play games online for real money you don't have to worry about much, the law is much clearer and simpler on that point.

So Are They Legal Or Not?

Many British players are wondering if visiting and using the services of a UK casino online is legal. The answer to all these players is a loud, resounding yes. It's legal in nearly every instance for players from Britain to gamble over the internet.

Unlike in other sections of the world, where gambling law is confusing, it's pretty straightforward here. If you're worried about any legal risks for enjoying yourself online, don't. There's no need to worry. You can find out more in our guide to UK gambling legislation.

Online Casino Regulation in the UK

Not only is gambling legal in the United Kingdom, but an online casino in the same country will be highly regulated. That means players using the services of such a casino don't have to worry about being ripped off.

The software is reliable, the pay-out percentages are fair, and players pretty much get a fair deal when using these online legal casinos. The same can't be said about the unsavoury alternatives to a legal online casino in the UK. That's because many illegal sites have little regulation.

A legal casino online has to be fair and offer a setup that players can trust as they play. The UK Gambling Commission makes all the major decisions about whether to allow a casino to open up or not depending on its adherence to regulations.

How We Find The Best Legal Casinos

Through careful research we took all the questions out of starting up with a new online casino. We looked through lawful options and ranked them carefully, giving you access to the best of the best.

These casinos are carefully vetted to not only be legit, but simple to use and fun for everyone involved. Here's a breakdown of what we look for in casinos.

  • Careful regulation
  • Simple deposit and withdrawal
  • Quality real cash games
  • Reliable software

Each of these aspects is equally important, and that's why we rate casinos on each of these characteristics. A quality casino online should be something a player trusts. It's little consolation that a UK casino is legal if it doesn't offer a good experience. That's why it makes sense to rely on our ratings to find the options that offer both.

Don't pass over the top UK casino because you don't know how to carefully research the different options. Let our team find a legit site for you to play for real money at. You'll enjoy the quality entertainment, and more importantly you'll know it's all completely safe. That's the benefit of our ranking system.

Stop searching in vain for the right casino and get started straight away with one of our UK casino recommendations today.

Frequently Asked Questions

Is online roulette legal to play in the UK?

As long as the online casino your roulette game is hosted on is licensed by the UK Gambling Commission and you are of age (18), it's perfectly legit for you to play online roulette there.

This goes not only for all types of roulette, but most other popular casino and table games as well as sports betting and lottery games.

What if I don't live in the UK?

If that's the case, then it's up to you to find out the laws regarding online gambling in your local jurisdiction.

More often than not, you'll have to pay taxes on your real money winnings (if it is in fact legal to play on UK-based gambling sites).

Do my real cash winnings from legal online UK casinos get taxed?

Unlike in some other countries, the great news is that no! If you're UK resident you are not required to pay taxes on your gambling winnings.

This wasn't always the case, but since 2001 gamblers don't need to pay a tax on their real money winnings from casinos, lotteries, sports betting, and online gambling.

What is the lawful age to play at a legal casino online?

Since the passing of the Gambling Act 2005, the minimum legal age to gamble online for UK residents is 18, as it is with land casinos and most slot machines.

Is it legit to play at non-UK based casinos?

Many popular bookmakers and online gambling companies have offshore operations, but it wouldn't make much sense to play on these as you would then have to pay the local taxes of wherever those sites are based.

How do I know if a UK casino online is actually legal?

By following our recommendations!

Seriously, if you stick to the sites we recommend right on this page, you will only find the very best online legal casinos that offer great bonuses, strong security, and of course are completely legal for UK players to play.
