Complete list of British online Casinos

Published on 30/08/2019

What a mess? Looking at the list of UK Gambling commission, I see hundreds of British online casinos holding a licence in the UK. The trick is, most of the license holders take the advantage and go live with dozens of domains. That way they are trying to cover as much of the market as possible. Fair enough.

This brings us to the point when we realize that the competition in UK gambling market is huge, however not as huge as it seems. Some operators have even over 20 British online casino domains operated by the same staff. This is indeed not making the mess any better. Take a look at our table of licensed British casinos. We were trying to make present a wide selection of competitors, but some of the brands have the same roots.

Why do we promote more brands from the same financial backgrounds?

The answer is "simplicity". Recently, after the regulation got tighter, we have full hands of testing each brand for fair play, bonus quality, customer service knowledge and other important features. We are responsible to bring a valid information. If we fail, we pay!

We made it simple for us by checking the customer service only once - instead of 10 times. We know that British online casinos follow a bonus pattern through all of the domains. This makes it easy for us to pinpoint a crappy condition in all the domains. We see the same wagering or no wagering, very similar conditions of bonus release, restricted games or math behind the bonus.

Just doing the math behind the casino bonus takes quite some time and in recent fast world, only the productivity pays off.

Many people keep searching for the complete list of British online casinos. Please, give it up! In our list of British casinos you find enough of them. You find there the big brands but also small ones fighting hard for each player.  The giants are rather subtle in the bonus offer, the small ones are slightly more generous but rather complicated.

I reviewed many British casino bonuses and from what I learned I can say "The benefit from most of them is very similar". Why do I claim it? Because of the math behind it. If you are about to do it on your own, feel free. Here is how I do it. Take the bonus amount, multiply it with wagering and take into account the RTP of a slot game.

A concrete example of casino bonus calculation

might look like this...

Conditions: The bonus £100 with wagering 30 is forcing you to wager £3000. RTP of the slot machine is let us say 95% - normally it is higher, but this makes the algebra easier. With each spin you are losing in average 5%. Let's say each spin is £100 - again, this never really happens but makes the calculation easier.


  • £100 x 5% = 5 / this amount you in average lose with each spin
  • 30 x 5 = 150 / this is the amount you lose in average after you wager £3000
  • From the facts you see that casino is "giving" you £100 as bonus money but is crooking the probability to take statistically £150 away. This is indeed not possible, but it makes the probability working in strongly their favor.

Please keep in mind the numbers from the example are showing averages on a big scale. A Player might end up happy or lose it all with a few spins.
