List of 400% deposit Bonus Offers in the UK

How We Evaluate Casinos with 400% Bonuses

Before we recommend a site with a 400% match deposit bonus, we thoroughly review what it’s offering. For a casino to make it onto our list, it needs to meet our high standards, and we don’t just look at the promotions. Check out our comprehensive criteria below.

Withdrawal Limits

Part of the fun of playing at casinos is collecting your winnings. We want that process to be straightforward, so we look at the minimum and maximum limits set by the casino. They should be accessible so you can withdraw what you want when you want.

Available for Players from the UK

This list is for UK players, so if a casino doesn’t accept them, it doesn’t earn a spot. When reviewing potential sites, we explore EU Casinos available in the UK as well as those in other locations, as long as a UK player can register and play.

Match Bonus Terms & Conditions

A casino bonus is much more than the amount you receive. There are always strings attached, but we’re here to review how reasonable the rules are. We check the expiry date, wagering requirement, minimum deposit amount, any caps and limits and excluded games.

Registration and KYC Procedures Are Simple

While it is rare to find websites without KYC verification, there are a few options with top-notch bonuses. Even if KYC is in place, we make sure that you don’t have to jump through hoops to get verified before withdrawing your winnings.

Unrestricted Play for GamStop Users

We’re focused on sites with bonuses that aren’t on self-exclusion network databases. If you’re looking for GamStop-free casinos, we make sure that the ones on our list fit the bill. You’ll be able to play at these sites without restriction but can still use responsible gambling tools.

Benefits of Online Casino 400% Bonuses

You can expect plenty of positives when you claim your 400 casino welcome bonus. Registering at one of these casinos brings plenty of fun and entertainment, as well as the benefits that we’ve listed here.

Potential Winnings Are Higher

The bottom line of a generous deposit match is that you have more to bet with. When you can place more bets and play more games, then you have more opportunities to win. Keep in mind that you need to meet the wagering requirement and stick to the bet limits, but otherwise, enjoy the enhanced potential.

Opportunities for Trying Games Without Risk

A large percentage match means the casino is adding more to your bonus balance than you are to your cash balance. You can make the most of that by trying out lots of different titles in the library. With over 5,000 to check out, you can explore with decreased risk at Crazy Star Casino.

Casinos Function Outside of UK Regulatory Control

All of the options on our list have top deposit match packages and bonuses. Most importantly, they are casinos without UK licence that accept British players, providing engaging gaming experience. If you’re looking for a site that’s not under UK regulation but that has a generous bonus, every one of these casinos ticks that box.

Casinos Not Linked to GamStop

Since these casinos aren’t regulated by the UK Gambling Commission (UKGC), they aren’t listed on the GamStop database. If two of your top priorities are a non-GamStop site and a generous welcome bonus, then you’ve got what you need right here. You won’t need to worry about the network’s self-exclusion list.

Minuses of Online Casinos with 400 Percent Bonus

We can’t deny that 400% deposit bonuses are fantastic, but that doesn’t mean that there aren’t some downsides, too. Let’s explore the potential negative aspects that come with choosing one of these sites and claiming a bonus.

Limited Number of Payment Methods

While you might find large bonuses and even larger game libraries, some lists aren’t so extensive. If you pick one of these sites, you might find that the choice of payment methods is limited. Typically, they accept credit cards and cryptos, but you might also find one or two e-wallets.

Higher Wager Than at Casinos with Lower Bonuses

The wagering requirement is a crucial factor when it comes to enjoying the bonus, as it affects your ability to withdraw your winnings. These casinos tend to have higher playthrough amounts than casinos with lower match percentages. They can go up to 40x or 50x, which can be challenging to clear.

Restrictions on Additional Bonuses

Since many of these bonuses are welcome packages, you might find that you’re restricted when it comes to claiming other promotions. Some casinos have rules that you need to claim and meet the welcome bonuses before you can benefit from any other offers. It could mean missing out on specific promotions.
