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!
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 offers!

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.
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.
