Safe and secure online casinos

We only review and rate online casinos that are licenced to operate in the UK. Always. But why?

Because only sites with a UK licence are legally allowed to operate in Great Britain.

In our view, these are the only safe, secure, and trustworthy casinos for UK players.

Obtaining a UK licence is no easy feat. Casinos have to pass strict tests and requirements before they get one. So sites that have a licence have met these requirements – so they are confirmed to have high security and safeguarding standards for players.

Secure online casino UK – How to pick

The first thing to check is if a site has a licence from the UK Gambling Commission (UKGC). Any gambling site without one is not operating legally or credibly, so they should be avoided.

All UK sites on Gamblermaster have a UK licence. So we’ve done this first step for you.

The strongest and most secure casino sites should also have:

  • Strong encryption across their site
  • Prominent responsible gambling tools
  • Secure payment methods
  • Clear privacy policies

Non-UKGC sites such as those not on Gamstop do not always have these features.

Trusted online casinos slots for real money

Online casinos partner with third-party game developers to provide the slots and games you play. So clearly they must be trustworthy too.

But licenced UK casinos are only allowed to partner with game developers who have been approved themselves. That’s another rule of the UKGC. This guarantees that you’re only ever playing fair and safe online slots for real money.

Every single online slot and casino game in the UK is tested for fairness and quality. This is done by an independent test house. They conduct tests to confirm that every game is fair and plays as it should.

UK casinos are only allowed to use test houses approved by the Gambling Commission. This means that casinos can’t bypass this security step by using a rogue testing company. Everything has to be done fairly.

Safe UK casinos

Is there a casino that’s considered the most trusted in the UK?

It’s hard to say.

If you’re judging based on security measures then it’s unlikely. The top sites (such as those listed above) are all as safe and secure as each other.

So we’ve judged them in a different way.

Which casinos are offer the fairest terms and conditions? Who pays out the quickest on time? These are both aspects that each casino controls. So those who do well are what we consider to be the most trusted.

For example, even the best casino bonuses UK mostly have wagering requirements. A wagering requirement prevents the player from withdrawing the bonus straight away. Instead they must bet many times before the money is considered real money that the player can withdraw.

Wagering requirements aren’t loved, as you can imagine. But most players understand why they are there. It’s casinos that set ridiculously high wagering requirements that we don’t consider to be the most trusted. Because they are deliberately making an already difficult task even harder to complete. So very few players will actually ever be able to cashout a bonus.

So what would make players trust a casino more? One that does not have wagering requirements. Anything the player wins is paid as cash. This is a much more enjoyable experience as players can focus on playing rather than tricky terms and conditions. There are even casinos with no wagering requirements. We consider these to be some of the most trusted in the UK.

Although all UK casinos with a licence must payout a player’s winnings as long as they have been won without breaking any terms and conditions, there are a few casinos that drag their feet. Days or even weeks can pass by with the player waiting for their cash.

Sometimes this is acceptable. For example, if a casino asks you for extra verification documents. Because a requirement of their UK licence is to prevent money laundering. So sometimes you may be asked to prove certain things.

But it’s casinos that don’t communicate properly that aren’t very trustworthy. For example, they might not tell you that extra documents are needed. Other sites might take ages to actually consider your withdrawal request. And on it goes.

So a casino that deals with withdrawals quickly is another trait we consider to be very trustworthy.

For example, many sites are classed as instant withdrawal casinos UK. This doesn’t mean you’ll get your money as soon as you hit withdraw. But it does mean they offer payment methods that can send payouts instantly, once they’ve been approved. We also prefer sites that try to approve payouts the same day. Because this shows they care about giving players their winnings, not just taking deposits.
