The Best 500% Deposit Bonus in the UK
500% matched deposit bonuses are some of the rarest—and most valuable—bankroll boosters you’ll find in the online gambling world, giving you a whopping five times your deposit amount in bonus funds! A £20 deposit, for example, would bring your bankroll to a whopping £120—and this makes these bonuses excellent for pretty much any type of player!
Casinos Offering 500% Bonuses
A 500% deposit bonus is a rare find, but when you do come across one, it can be an incredible way to boost your bankroll. Since these bonuses give you a huge increase in funds, they’re not as easy to find as 100% or 200% matched deposit bonuses, but they can be found.
They’re often reserved for VIPs, but if you know where to look, you can find them offered to new customers too—and on this page, I’m going to show you exactly where to find these highly lucrative deposit bonuses offers!
To help you, I’ve put together a list of the best UK casinos that offer 500 deposit bonuses. Check out my recommendations below:

How We Review Casinos
When reviewing 500% deposit bonus casinos, I focus on a range of factors to ensure that players are getting both a valuable and fair experience. The first thing I check is licensing and regulation—any casino offering this type of promotion must be fully licensed and have a trustworthy reputation.
Once I’m happy with this, I look at the bonus’ terms and conditions. A 500% deposit bonus sounds exciting, but if it comes with ridiculously high wagering requirements or low max cashout limits, there’s little point even claiming it to begin with! I also look at things like game variety, payout speeds, and customer support facilities.
Types of 500% Deposit Bonuses
Today, there are a few different forms of 500% deposit bonuses you will come across – and below, we’ll explore what these are, and how they look:
Are 500 Deposit Bonuses Worth It?
A 500% deposit bonus can be one of the best ways to increase your bankroll, but it’s not always the right choice for every player. If the bonus comes with fair wagering requirements and reasonable withdrawal limits, then yes—it can be a solid choice.
However, if the bonus has really high wagering conditions, low maximum cashouts, or heavy game restrictions, it might not be as good as it seems. That’s why it’s important to play at one of the casinos recommended here at KasinoBonus, so you can ensure you’re getting the best bonus possible.
Top UK Casinos With 500% Deposit Bonuses
While 500% deposit bonuses can be hard to come by, there are many online casinos in the UK offering them – and one of our favourite offers available right now is from BoyleSports. This well known online casino and sports betting site is currently offering all new players a generous 500% bonus – and to get started, you just need to make a deposit of £10! Your bonus funds can then be used on selected video slots, and you have 48 hours to complete the bonus’ wagering requirements!
| Casino | Bonus Details | Wagering Requirements | Key Terms |
| BoyleSports | Stake £10 Get a £50 Casino Bonus | 40x | Min Deposit: £10, 24 hours to accept, 48 hours to stake, 168 hours to complete wagering requirements. |
Terms and Conditions to Be Aware Of
A 500% deposit bonus is one of the most generous promotions you’ll find at an online casino, but it almost always comes with strict terms that you should understand – before touching any of your bonus funds. Firstly, there’s the wagering requirements – and these tend to be quite high – often 50x or 60x. These wagering requirements can be applied either to just the bonus funds, or the entire bonus – and they must be completed before you can request a withdrawal.
Another thing to bear in mind is that 500% deposit bonuses can usually only be played on slots. If casino table games and live dealer games can be played, they generally do not contribute to the wagering requirements – or, if they do, at a minimal percentage – maybe 10%. While playing with your bonus funds, you’ll also usually find that you’re limited to the amount of time you have to complete the wagering requirements – 7 days is standard, but some online casinos give you as little as 48 hours!
How To Claim a 500% Deposit Bonus?
Claiming a 500% deposit bonus is, thankfully, very simple! To get started, follow the simple steps below:
