Best UK Deposit Bonuses - Get up to 500% Casino Bonus

A deposit bonus is a general term - make a deposit into your U.K. casino account and get a bonus. It’s not difficult at all to grasp the concept, but there are usually some T’s & C’s making it a bit more tricky.

On this page, we’ll touch upon some of the most common casino bonuses. In general, all UK casino bonuses are deposit bonuses (with one exception). All bonuses are also bound to specific terms and conditions. These terms and conditions, together with the actual bonus, make up the overall quality of the deposit bonus. So before you dive in head-first, take a moment to compare. All important details are clearly laid out, as Mr. Gamble always does - we lay it out for you to play it out.

No Deposit Bonus UK

Just like the name suggests, this is not a deposit bonus. A no deposit bonus is a different kind of bonus. Many UK casinos offer this as the very first bonus to their newest players. It’s one of the very few freebies.

The casino offers this bonus to give us a chance to try it all out. Usually, it’s in the form of a handful of free spins, but some casinos offer a small amount of bonus money. We can’t simply take the bonus money, withdraw it, and leave the casino. No, the bonus is usually tied to a selected game or a few, and the bonus is also subject to a wagering requirement, just like all other casino bonuses.

To read more about this, please visit our dedicated page to learn everything about no deposit bonuses.

UK Welcome Bonus

Get deposit bonuses

The welcome bonus is one of the most popular casino bonuses in the UK. This is mainly due to the large bonuses with lots of bonus money or a ton of free spins. Some casinos even offer lots of both.

Some UK casinos offer an entire welcome package, covering more than your very first deposit only. The best welcome-packs offer a bonus on your 4 first deposits. Other casinos go big on only the first deposit, offering up towards 500% bonus money on top of your own deposit. It’s rare but you can find them. Just visit our page dedicated to welcome bonuses and general casino bonuses, apply your own filters and find the best offer for you.

While on the topic of welcome bonuses, we want to take the opportunity to highlight some important things. These things are the wagering requirement as well as restricted games.

The wagering requirements are different from one casino to another. In our reviews and in our lists, we highlight the requirements. It gives an easy overlay of the bonus wagering, whether you have to wager the bonus money only or both the deposit and the bonus money. This can make a huge difference. We’d also like to add that you should check out the different games’ contribution towards the wagering requirement. Live casinos will often not contribute at all towards the wagering. Some slots are also excluded while table games tend to be 50/50.

Freespins Deposit Bonus UK

UK players love their free spins, and do do we at Mr. Gamble. We love the concept of spinning the wheels for free while being able to win real money. The most common way to get lots of free spins is via the UK casinos welcome bonuses. Some casinos offer hundreds of free spins as a welcome bonus. But, here’s the trick: It’s easy to find large amounts of free spins, but it’s more difficult to find lots of free spins to great Terms and Conditions

Another way to get free spins is to play at a UK casino that offers recurring free spins bonuses. This is most common at casinos who’re arranging weekly slot tournaments.

Reload Bonus UK

The reload bonus is a frequently occurring bonus at many UK casinos. Some casinos offer this bonus several times per week. It has a simple set up, make a deposit and get some bonus money. The percentage is up to each casino to decide. A very common reload bonus is 50%. This means if you deposit £100, you get £50 as bonus money and a total bankroll of £150.

As usual, there are Terms and Conditions attached to the bonus. It’s always important to be on top of this and understand what’s required before taking casino bonuses. 

UK Cashback Bonus

This is another simple goodie of a bonus. Casino cashback bonuses work in the same way as the general cashback programme. For everything you lose, you get some back. In the case of online casinos, you’ll get back a percentage of your total losses over a period of time.

If you’re offered a weekly cashback bonus of 10% it means that 10% of your losses are re-paid to your casino account every week. You have to opt-in to be able to participate.
