The Best Casino Welcome Bonuses For UK Players (Regularly Updated)

 A welcome bonus from a casino gives you a chance to double or quadruple your first deposit

Finding the best casino welcome bonus is a really valuable use of your time as a gambler. Why? Because it can get you some free spins and some free money. 

The reason for this is that welcome bonuses are rewards that online casinos give to new gamblers. 

Casinos offer these incentives because it tells gamblers that they can place wagers without spending their own money. The thing is, though, that welcome bonuses aren’t quite free and it can be difficult establishing which casino offers are the best ones. 

That’s where we come in. 

Please be aware that all bonuses and promotions mentioned in this article come with the following conditions in order to meet UK casino compliance laws:

Best sites for cash casino welcome bonus 

 

Why the cash offer matters when reviewing the best casino welcome bonuses 

Getting a cash reward just for signing up to a casino and depositing a bit of your own cash is probably the welcome bonus gamblers care about most – after all, it’s free money (well, sort of). 

You must read the full terms and conditions of all cash bonuses and keep an eye out for these things. 

  • How much of your own money you need to deposit 

  • How many different deposits you need to make 

  • How much time you have to make the cash deposits 

Best site for cash welcome bonus: Grand Ivy Casino

You must make three deposits to get the £1,500 welcome bonus on offer from Grand Ivy Casino.

Why the free spins matter when reviewing the best casino welcome bonuses 

Free spins are a great welcome bonus – they allow you to play some of the best slot games for free and all you have to do is deposit a little of your own money. 

What you need to know is that these free spins do come with some conditions, such as: 

  • Only being available for certain games 

  • Only on offer for a set number of days 

  • Only being dished out in daily doses

Why wagering requirements matter when reviewing the best casino welcome bonuses 

The wagering requirement is the amount of the cash or spin bonus that you need to deposit before you can make a cash withdrawal. 

This is super important because it tells you how much of your own money you need to spend before you can get your ‘free’ cash or spins. 

Using the example of a £100 cash bonus, this is how wagering requirements work:  

  • 30x = £100 x 30 – you need to deposit £3,000 of your own money to get the bonus

  • 40x = £100 x 40 – you need to deposit £4,000 of your own money to get the bonus

  • 50x = £100 x 50 – you need to deposit £5,000 of your own money to get the bonus

How to get the best casino bonus

Three blue dice, three green dice, and three red dice rest on a brown wooden table

Almost every online casino offers a welcome bonus – it's in their interest to do so because it’s a way of drawing in new gamblers. 

But because so many sites offer these rewards (often at similar amounts) it can be difficult getting the best bonus. 

There are three steps you should take to help get the best bonus

  1. Decide what bonus you want – free cash, free spins, or a combination 

  2. Read reviews of the top gambling sites and find the ones with the best offers 

  3. Go through the wagering requirements needed to get these bonuses 

FAQs

What’s the difference between cashable and non-cashable offers? 

While there are two main types of welcome bonus (free spins and free cash) there are also two different types of offer that you need to be aware of – cashable and non-cashable. 

  • A cashable offer is a bonus you can withdraw into your account – it’s real money. 

  • A non-cashable offer cannot be withdrawn – it’s casino credit. 

What games can I play using the welcome bonuses offered by casinos?

One of the most important things to be aware of with casino welcome bonuses is that they can often only be used on certain games – something particularly true of free spins. 

Check the T&Cs of the casino reward you’re interested in to find out which games you can use the offer on – the site has to display this information. 

How to cash out a welcome bonus

If you’ve picked a welcome bonus that can be cashed out and deposited into your own bank account then there are two main ways you can make this happen: 

  1. Meet the wagering requirements for getting the bonus 

  2. Using the payment conditions and gateways specific to the casino providing the offer

What are the terms and conditions of a casino bonus?

The terms and conditions of a casino bonus are incredibly important – they are the requirements and stipulations attached to any reward that’s advertised by a casino, with their intention being to protect both gamblers and casinos. 

The specific terms and conditions of a casino bonus vary from casino to casino and bonus to bonus. One of the key details consistent with all T&Cs is that they ensure any reward complies with the national legislation it is required to.
