UK Casinos With Best Sign Up Bonuses

A sign up bonus is an offer that the best online casinos use to get gamblers to create an account for their website or gambling app. 

These rewards are generally cash or free spins, but they can sometimes come as casino credit to be used on the site you’ve signed up to. 

While some people may believe a sign up bonus is free money they can use on their favourite casino games, the reality isn’t quite so simple – there are often requirements you need to meet to get the full bonus, meaning that you might have to spend your money.

Total sign up bonus: ⭐⭐⭐⭐⭐: £5 no deposit bonus + £1,200 cash welcome bonus + 100 free spins

bCasino isn’t the number one casino for any of the main sign up bonuses we look out for, but it has an exceptional overall offer. When signing up, you get a no deposit bonus, cash welcome reward, and free spins offer, giving you everything you could want from an online casino. 

However, there is one thing you need to know about the free spins – it’s an offer available upon sign up every Wednesday, but you do need to make a £20 deposit each time you want to get it.

Total sign up bonus: ⭐⭐⭐⭐⭐: £100 cash welcome bonus + 300 free spins 

If you’re a fan of slots then Genesis might be the perfect casino for you – your sign up bonus gives you 300 free spins on Starburst, one of the best slot games you’ll find at any gambling site. 

The 300 free spins you get from Genesis is the most of any site we reviewed – it’s 50 more than mFortune and Jackpot247, which both offer the second most spins out of the casinos we’ve covered.

As well as spins, you also get a £100 cash welcome bonus. However, you don’t receive a no deposit bonus, which is reason enough to make Genesis one of the best casinos for new players.

Total sign up bonus: ⭐⭐⭐⭐⭐: £200 cash welcome bonus + £21 no deposit bonus + 77 free spins  

Cash welcome bonus? Tick. No deposit offer? Double-tick. Free spins? Another tick. 

While 777 doesn’t excel in any single sign up bonus category, what’s important is that it ticks all the boxes – something that only a few casinos can claim to do. 

One thing to be aware of is that 777 does have high wagering requirements. Its 50x puts it at the top end of the scale, meaning you need to invest a lot of your own cash to get full value from its bonuses.
