Bonus Varieties to Match Your Style

Best Bonuses For UK Players

You’ll be pleased to learn that your top online casino of choice probably offers a handful of different bonus types. Most come in the form of a ‘match’ offer, which means the casino matches the amount you put down, at a certain percentage. But there’s more than that. At online casinos in the UK, you’ll find the following varieties:

Welcome Bonus

Sign-up bonuses are basically free cash you get for signing up with a new online casino. These offers are usually match bonuses that can double the amount you initially put down. With a 100% match bonus, for example, you’ll get £200 total for your initial £100.

Deposit Bonus

A deposit bonus will give players extra bonus cash on top of a real money deposit. These often come as match bonuses, so you could stand to earn more than double your initial deposit if the match is over 100%.

No-Deposit Bonus

Here, the casino will offer players free money to play online casino games, with the upshot that you don’t even need to make a deposit first. Of course, these types of bonuses are generally smaller in amount, but are great ways to get a feel for a new online casino site.

Loyalty/VIP Bonus

The longer and more you play, the higher your chances of scoring a loyalty bonus are. Many top online casinos in the UK reward players with points throughout their playing time, which can be redeemed for bonus cash after a certain point.

Reload Bonus

A reload bonus gives cash back to loyal players who have already made their first deposit but may have decreased their playing time as their initial funds were used up. Usually, a reload bonus comes as a percentage of the initial bonus. A 50% reload bonus would give you £250 on a deposit of £500, but with some, this £250 might be paid out in instalments.

Referral Bonus

Score a referral bonus for getting a friend to sign up with your favourite online casino. Generally, you’ll get a specific percentage of their first deposit. With an 80% referral bonus, for example, you’ll make an easy £80 on your friend’s £100 deposit.

Match Bonus

A match bonus simply means that for every pound you deposit, the casino adds another in free cash. Match bonuses come at different percentages, some even exceeding 100%. If a casino offers a 120% match bonus and you deposit £100, you’ll wind up with an extra £120.

Cash-Back Bonus

A cash-back bonus is essentially a refund on a percentage of your losses while playing. If you’ve lost £100 on the slots, for example, a 50% cash back boost will put £50 right back in your wallet. There’s really nothing to lose with this type of promotion!

Payment Method Bonus

Free cash just for using a particular payment method? Not a bad deal! Some sites offer payment method bonuses for making deposits in Bitcoin, for example.

How to Redeem Your Exclusive Bonus

Top online casino sites in the UK should be open and upfront about the terms and conditions involved in claiming your bonus. Be sure to take some time to read through any requirements given, and note that some bonuses may also be time sensitive.

Wagering Requirements in Depth

It’s hard to underestimate the importance of bonuses for online casino players. Bonus cash allows you to test the waters of new games for free, or to sign up with a new UK casino and get a feel for the site without investing too much of your own money.

But one common misunderstanding among new players is that they can simply cash out on their bonuses and never look back. Of course, an online casino site wouldn’t offer bonuses without the hope of retaining players. Rather than pure cash, bonuses should be viewed as a jumping-off point for your future payouts.

All top casinos follow different rules when it comes to cashing out on your winnings, but most require you to either play for a certain amount of time or bet a specific amount of money before you can withdraw your winnings. This is generally referred to as a casino’s ‘wagering requirement.’

To understand wagering requirements, let’s look at an example.

  • Say a casino offers a 100% matchup for up to £200, and you go in for the full amount.
  • You put up £200 and receive another £200 in bonus cash, for a total account worth of £400.

But how much of this cash can you actually withdraw?

  • Your UK online casino has set the wagering requirement to 10 times the wager plus your bonus.
  • £200 x 10 = £2,000
  • You’ll have to wager £2,000 before you can cash out on that bonus.

Steer Clear of Blacklisted Casinos

No matter how good the welcome offers might seem, certain online casinos just aren't to be trusted. Fortunately, we communicate with players and make note of any online casinos in the UK that have gotten negative feedback from players, for failing to maintain the standards of online gambling.

If you want to keep your winnings safe, it's best to avoid these blacklisted casinos.

What is an online casino bonus?

An online casino bonus is a promotional offer from top casinos in order to attract and retain players. Essentially, players are given free money, available under certain terms and conditions, for performing certain actions within the site.

Which online casino offers the best bonuses?

The top recommended casinos on this page all offer some significant bonuses. Which casino has hands down the best bonuses depends on which bonus variety we’re talking about, and the specifics of how you want to play.

Should I always pick the biggest bonus?

Many players are attracted by casinos that seem to offer the best welcome bonuses, but then find out that it was a shady operation to begin with. Be sure to check out our blacklist for information about untrustworthy casinos.

Can I use my bonus for every type of game?

Certain bonuses are specific to one type of game, or only count bets made on a certain game (e.g. roulette) towards your wagering requirement. Other casinos offer free spins as a bonus, which can only be used on the slots, for example. There are also many bonuses that may be used throughout the entire online casino, but it’s all the more reason to read the terms and conditions before claiming your exclusive bonus.

Can I withdraw my bonus?

You can withdraw your bonus as long as you’ve met the wagering or play requirement at your online casino. This is usually a specific amount of your own money you have to bet before you can cash out.

Are casino bonuses only for new players?

No. There are many types of bonuses available for existing players, such as a banking method bonus, a loyalty bonus, or a reload bonus.

Are there bonus codes available?

Bonuses come in many shapes and sizes, whether as free spins or bonus codes. Many of our favourite online casinos are currently offering players new promotional deals, so check out their websites to take advantage of bonus codes.
