The UK's Best Casino Welcome Bonus Offers in 2024

5 of the Best Online Casino Bonuses in the UK

Whoever said variety is the spice of life could have been referring to online casino bonuses. We're pretty sure they weren't but the idea is true! There are hundreds to choose from and this is a good thing – competition keeps online casinos honest and their bonuses attractive.

But having so many options can also lead to 'analysis paralysis' as you spend hours comparing each one. To avoid this, our experts have come up with a list of seven fantastic casino bonuses for different purposes. For each one, someone from Casinos.com signed up and claimed the bonus to test it out.

Best Casino Welcome Bonus for New Players: Party Casino

• Features: 100% deposit match up to £250 (£10 minimum deposit).
• Wagering requirements: 35x deposit amount. Eligible games: slots 100%; video poker, roulette, other table games, and live games 20%; blackjack 10%.
• Need to know: for new UK players only. The maximum stake per bet is £5 for slots and £50 for other participating games. You have 30 days to use up the bonus. To claim you must deposit using only VISA, Mastercard, ApplePay Direct, ApplePay or Paypal.
• Our view: we were really impressed with this UK casino bonus when we claimed it. It was easy to activate it by depositing money using one of the specified payment methods (we used PayPal), and the terms are really generous. We loved the variety of games covered, including live casino games, even if it only counts for 20% of wagering requirements. If you're looking for a big welcome bonus casino, it may be time to Party Casino.

Best Casino Deposit Bonus: Mr Vegas

• Features: 100% deposit match up to £200 + 11 extra spins.
• Wagering requirements: 35x your initial deposit. The free spins come with no wagering requirements.
• Need to know: activate the bonus by heading to the ‘My Bonuses’ part of your profile within 30 days of making your deposit. The bonus will be credited to your account in ten equal instalments. The max you can wager on any bet is 50% of your bonus amount or £20 – whichever is lowest. You have 60 days to complete the wagering requirements.
• Our view: we loved the generous timeframe to claim this casino deposit bonus, and 11 free spins with no conditions attached is not to be sniffed at. The bonus can be applied to all sorts of games too, including slots, table games, and the live casino.

Best Low Wagering Bonus for Quick Wins: Kwiff Casino

• Features: 200 free spins on Book of Dead (£0.10 per spin). Divided over 5 days: 40 free spins for each day you wager £20 on any slot.
• Wagering requirements: no wagering requirements for any winnings you make!
• Need to know: winnings from this UK casino bonus are capped at £250. This promotion is for new customers only, and you can't use e-wallets or virtual cards to make deposits. Oh, and you can’t claim this bonus alongside other casino offers, so if you take up their sportsbook promotion you’ll be shut out of this one.
• Our view: it’s really rare to find casino bonus sites offering deals with no wagering requirements at all, but this is one! Our tester was a huge slots fan who happens to rate Book of Dead highly, so she enjoyed the 40 extra spins each day. Just remember that you need to deposit at least £20 each day to get the full 200 extra spins. The great news is you can use your bonus bankroll on any slot in Kwiff’s library – and they have a few hundred to choose from. 

Best Casino Bonus for Slots: Spin and Win Casino

• Features: get a £7 bonus plus a 100% deposit bonus up to £500 to play on any of their 33 ‘top slots’.
• Wagering requirements: 40x on your total bankroll (your deposit plus bonus amount). 
• Need to know: you have to enter the code WELCOME when you first make a deposit of at least £10. The bonus is valid for only 7 days from the time it’s activated, so don’t hang around!
• Our view: Spin and Win, as you may have guessed, specialises in slots, so it’s no surprise that its promotion is one of the best casino bonuses in the UK for slots. The £500 limit is generous, but the wagering requirements are on the high side. But the thing we were most impressed with when signing up was the fact that, unlike most other slots promos where you’re forced to play one title, we could choose from 33 different ones, including titles like Bonanza Megaways, Fishin Frenzy, and Book of Dead.

Best Cashback Bonus to Reclaim Losses: All British Casino

• Features: 100% deposit match up to £100 (£20 minimum) plus ongoing 10% cashback.
• Wagering requirements: no wagering conditions on the cashback facility. There is a 35x wagering requirement on the bonus amount – eligible games are slots 100%, video poker 20%, and blackjack 10%.
• Need to know: the cashback is calculated using your first deposit, and must be activated within 24 hours. Be warned though: if you use a VPN you may not be able to claim the offer.
• Our view: cashback casino bonuses are a great way to get some money back following losses, and this is one of the best. We were surprised to learn that, unlike the casino deposit bonus, the cashback bonus came without restrictions. If you want, you can simply claim the 10% cashback and withdraw it instantly if you want. We tested this and indeed it works exactly as they say.

How We Rate Casino Offers

Wondering how we arrive at the casino bonuses we recommend, when there are literally hundreds to choose from? Here are the stages our experts go through:

1. We check the casino bonus carefully. That means we take a close look at what’s on offer, whether it’s a deposit match, free spins, or anything else. And since there are a lot more to casino bonuses than the headline numbers, we dive into the T&Cs to see what conditions are in place. We check for wagering requirements; eligible games; time limits; caps on deposits, bets, and winnings; what payment methods are accepted, along with any other detail that’s important.
2. We sign up and claim the online casino bonus. There’s no point in us recommending a bonus that doesn’t do what it says, or has a painful sign-up process. To make sure, we test everything just as a real customer would, and if we think that this bonus is more trouble than it’s worth, it won’t make the cut.
3. We make sure the casino bonus sites are legit. Here at Casinos.com we only recommend the best casino bonuses from trustworthy sites that hold a licence from the UK Gambling Commission. We also provide full reviews of all UK casinos featured here, so you can see how well they perform in terms of game variety, game quality, user experience, banking methods, customer service, software options, payout rates, and security measures, alongside how attractive the casino sign up bonus is.

How to Choose a Casino Bonus: Expert Tips You Need to Know

It’s easy to get bamboozled by flashy offers and claims, but when it comes to casino bonuses the devil really is in the details. So before you sign up to an offer that seems too good to be true, these tips help you understand what’s in the small print.

Understand Casino Bonus Wagering Requirements

Wagering requirements are simply the number of times you have to wager the online casino bonus before you can withdraw any winnings. Even the best casino sign up offers in the UK will come with these conditions attached.

For example, let’s say you sign up for a £100 casino deposit bonus, and it comes with a 30x wagering requirement. In this scenario you’d have to keep betting the bonus and any wins you get from it until £3,000 has been wagered (£100 x 30).

Think of it like a 30-piece jigsaw puzzle. Each piece you lay down is like a new bet. You can only complete the puzzle and enjoy the final picture by first laying down all 30 of the pieces. Similarly, you can only enjoy the winnings once you have made all the necessary bets.

Other factors that affect how much you need to wager include whether the deposit amount is added to the bonus bankroll or kept separate. Also, different game types contribute different amounts to wagering (more on this next), while some games are excluded.

How Much Will You Need to Wager?

So how can you work out exactly what your wagering amount should be? By using our handy Wagering Calculator of course!

Some of The Best Casino Bonuses Ranked by Wagering Requirements

Find Out Which Games Are Eligible… and Which Aren’t

If you’ve ever signed up for an amazing UK casino bonus without realising it’s only playable on games you have no interest in, you'll know it's not ideal.

Simply put, most casino offers are only valid for select games. This could be a single slot game, a specified group of slots, or a mixture of slots and other table games. 

Not only that, it’s often the case that certain eligible games don’t count 100% to wagering requirements. Table games or live casino games, for example, usually count around 10–20% towards wagering requirements. 

What does this mean in reality? Well, let’s take the same example given above. A £100 deposit with a 30x wagering requirement means you must wager £3,000 in total before you qualify for any winnings. If your game of choice, e.g. blackjack, has a 10% contribution, every £10 you wager only contributes £1 towards that £3,000 goal.

So, if you only wanted to play blackjack online, you’d effectively have to wager £30,000 before you could claim any winnings!

As you can tell, it’s really, really important to know which games the bonus covers and, just as importantly, which ones it doesn’t.

Check When the UK Casino Bonus Expires

Another hugely important thing to know is how long you have to use up your bonus. After all, the last thing you want is to find the perfect promotion only to later find that you only had 72 hours to fulfil a £50,000 wagering requirement!

Casino bonus time limits range from hours to months, and that’s not all. While bonuses are often given out straight after making your first deposit, sometimes the benefits are staggered. So, you’re given a portion of the bonus each day or week until you receive all of it. And to make it even more tricky, each instalment may have time limits or wagering requirements, so remember to check!

Find Out if Deposits, Bets, or Winnings Are Capped

Even the best casino welcome bonus will have limits on how much you can deposit. For example, a 200% deposit match with a maximum bonus amount of £100 means that £50 is the most you can expect the casino to match. You can of course deposit more, but you won’t receive any more ‘free’ money as a result. 

By the same token, each game that’s eligible for the bonus is probably going to have maximum bet sizes attached to it. For example, it could be £0.10 per spin on a qualifying slot, or £25 for a single bet on a table game.

Why do the casinos do this? To avoid you winning too much on the back of a bonus, which would quickly see them out of profit. And to this end, another common condition is to cap maximum winnings altogether. That way, even in the worst case scenario the casino site is able to limit its losses while still giving players a healthy win if the maximum is achieved.

Make Sure Your Payment Method Is Eligible

This is something that trips up a lot of players. Many casino bonus sites are very particular about which payment providers can be used to deposit money for redeeming bonuses. If you’re not aware of this, you may waste a lot of time and money playing a bonus you have no chance of winning from.

Typically, super fast e-wallets are not eligible for claiming bonuses. This is because they provide anonymity, which allows people to sign up with different email addresses and claim bonuses several times. So you may need to use alternative online casino payment methods if you're used to an e-wallet. 

Therefore, you need to read the small print to make sure your payment method isn’t excluded from the bonus.

Don’t Forget to Activate the Online Casino Bonus

Finally, a tip that should be obvious but is possible to get wrong. In a nutshell, some bonuses are automatically credited to your account after you sign up and deposit money, while others need to be activated. This could be in the form of a casino bonus code you have to enter at the cashiers, or by going to your profile and selecting your bonus of choice.

Of course, if you don't activate the bonus, you won’t be able to enjoy the extra spins or money you thought you were getting.

Types of Offers at Casino Bonus Sites

There are always multiple types of online casino bonus on offer, so it pays to understand what they are. Here, we've broken down the most popular bonus types you are likely to come across.

Casino Welcome Bonus

Online casinos use welcome bonuses to help attract new players. You generally have to deposit some of your own money to unlock a casino welcome bonus, so it’s widely referred to as a matched deposit bonus. Let's take a look at how it works.

Let's say you find a 100% welcome bonus up to £200. That means if you deposited £200 of your own money, you’d receive an extra £200, giving you £400 to play with. A 200% welcome bonus up to £500 would see you given £750 to play with if you deposited £250 of your own money, and so on.

Just remember to check the wagering requirements and read the small print before deciding which is the best casino welcome bonus for you.

In our view, the following casino bonus sites have some of the best welcome offers right now:

No Wagering Casino Bonus

A no wagering casino bonus allows you to enjoy the free goodies without needing to worry about wagering requirements. This means if you win, you can withdraw your bounty after only playing the bonus once, rather than multiple times! This is why many players regard this type of offer as the best casino bonus in the UK. This bonus can take many forms, including casino no wagering free spins or  cash.

But as you can probably imagine, these promotions are rare. But some casino bonus sites, especially new online casinos, will offer no wagering bonuses as they back themselves to make such a great first impression when you try out the site that you’ll want to stay. 

Free Spins or Extra Spins

Using free spins in UK casinos gives you a package of extra spins on an online slot. Usually these are restricted to particular games, but some offers apply to a whole range of slot titles.

Extra spins can come in the form of a standalone bonus, or they could be part of a bigger slots welcome bonus in the UK. Extra spins could come with a deposit match bonus, for example.

Once you've used all of your free spins, any bonus money you win will be added to your account balance. At the best slot sites in the UK, sometimes the bonus wins will automatically automatically be withdrawable as cash, but usually this amount is subject to wagering requirements before you can actually make a cash withdrawal.

The following casino sites have excellent extra spins offers:

No Deposit Bonus

As the name implies, a no deposit bonus in the UK is essentially a freebie: you get a small bankroll to play with without making a deposit first. 

So what’s the catch? Actually, there are two. First, the amount you are given is usually much lower than for a deposit match bonus, which reduces your chances of winning. Second, wagering requirements on these bonuses are often pretty high, often in the ballpark of 50–60x.

Still, these bonuses are a way for you to try a new casino or game without risking any of your own money, so they’re not to be sniffed at.

Reload Bonus

Casino sites will often dish out reload bonuses to keep customers loyal. This is where your bankroll is given a top-up at certain times, or when earlier bonuses have been used up.

Reload bonuses are generally smaller than a welcome bonus, but they give you an added incentive to keep playing… and extra chances to win.

Loyalty Promotions

Many online casinos have systems in place to reward loyal customers. Generally this involves giving you points as you play, with more points awarded for higher wagers. 

You can then exchange these points for free bets, free spins, or other rewards. This is another tool designed to keep customers loyal, and it’s worth scrutinising, as it can help you make money when playing.

For example, you might receive 1 point for every £1 you bet on online poker or table games and 5 points for every £1 you bet on real money slots in UK casinos. Then, these points can be exchanged for bonus money or even special prizes like a far-flung holiday. A really generous loyalty programme can make the difference between earning a profit or incurring a loss over the course of the year.

Birthday Bonuses

It's always nice to get a little something on your birthday. Many online casinos like to get in on your celebrations, no matter how big or small your plans are. Sites will sometimes offer you a bung in the form of a casino birthday bonus -  usually a few free spins on a particular slot. Though we have also seen the occasional one-day deposit match from time to time, among other promos. Unlike some other bonuses you won't usually need to go in search of this offer yourself. Once you're signed up and verified at a casino, they'll naturally have your birthday on record. When your b-day rolls around, they'll get in touch either in your account area or by email and SMS to inform you of your gift.

VIP Bonuses

If you place a high volume of bets or you are classed as a high roller, you could qualify for VIP treatment. Such benefits may include:

• cashback on bets
• quicker withdrawals
• specific tailored bonuses
• lower wagering requirements
• a personal account manager
• birthday gifts
• tickets to concerts or sporting events
• trips
• gadgets and luxury goods.

Mobile Casino Bonuses

Some online casinos will offer unique bonuses for playing on their mobile casino, although these are pretty rare now. It used to be the case that casino sites would encourage players to offer bonuses as a way of encouraging them to play via mobile. But these days almost every casino has a mobile-first strategy, which means the site is designed to work just as well on mobile as on desktop.

Some operators go further, and create real money casino apps that you can download to a smartphone or tablet. 

Here are some of our favourite casinos to play on mobile:

Refer a Friend Programmes

Many casinos will reward you for encouraging friends and family to sign up for an account. The bonus you receive will generally be tied to the amount your friend deposits.

Of course, this bonus will also have terms and conditions, including wagering requirements, and a limit to how many times it can be used.

Live Casino Bonuses

Live casinos are well established in the UK today, with demand growing all the time. As competition is fierce, some casinos try to stand out by launching promotions for live games. 

If you sign up for a live casino bonus, you can play all manner of table games and other exciting games, while interacting with the dealer and your fellow players. However, even the best roulette sites will probably feature bonuses with more challenging wagering requirements than their promotions for slots.

Here are some of the best live dealer casinos to sign up at today:

New Casino Offers for Specific Games

You will often notice that casinos tie a casino bonus to certain games. Starburst, Gonzo’s Quest, Jack and the Beanstalk, and Twin Spin are common slot games that you will find tied to the latest casino bonuses. 

You may also come across bonuses linked to new slots, as the game developer, casino, or both try to encourage you to give the new game a go. 

We recommend the following casinos for their outstanding selection of games of all types:

How to Claim the Best Casino Sign Up Offers in the UK

Signing up for the latest casino bonuses is simple. Just follow these steps:

1. Use Casinos.com to identify the best and most reputable casino bonus sites in the UK.
2. Sign up with your personal details, choose a password, verify your email address, and provide proof of ID.
3. Read the terms and conditions thoroughly. Look out for wagering requirements, game eligibility, and minimum deposits to gain a full picture of the bonus rules.
4. Input the relevant code, if there is one, when you make your first deposit. If you don't enter the code, you could miss out on the bonus.
5. Make a deposit using an eligible payment method. Remember it's best to avoid Skrill or Neteller for your initial deposit. You will then unlock the welcome bonus and the funds will be credited to your account.

Remember, you can only make a withdrawal once you've completed the wagering requirements (if there are any). Once you've claimed your first casino deposit bonus, you'll be a fully-fledged member of the casino and you can receive reload bonuses and other ongoing casino promotions.
