Best Online Casino Bonus Sign Up Offers UK June 2024

Best Online Casino Sign Up Bonus June 2024

If you’ve ever played at the best online casinos before, you’ve definitely come across a welcome bonus. These are special offers for brand new players, and they serve a few different purposes. Firstly, a welcome bonus allows you to make your cash go further. For example, if you claim a 100% deposit match up to £100, you’ll get a total of £200 to start off with. The same thing goes for free spins - you can start enjoying the games without spending a whole lot of money.

The other major appeal of welcome bonuses is that they allow you to go ahead and test out all the features of an online casino site immediately, without a big monetary commitment. For example, you can start playing games on desktop or mobile, and check out how the user experience works.

And how could we forget, welcome bonuses give you the chance to win some real money. While they might come with T&Cs like wagering requirements, that doesn’t change the fact that you might get lucky enough to land yourself a big win.

So, which is the very best online casino sign up bonus for players in the UK? Well, that’s a hard question to answer, because they’re all so different. While deposit match offers are the most popular type of bonus by a mile, some casinos give you a free spins no deposit instead, while others still might award cashback. Plus, every online casino player has different priorities, so that’ll determine exactly what you’re looking for in an offer. For example, some players might prefer a big batch of free spins on a game they already know and love, while others might be looking for a generous deposit match so that they can go off and play a whole range of different games.

If you’re ready to claim your casino welcome offer, the best way to do it is by clicking on a link on this page at Bookies.com to go off to the casino site. You can then create your account and use the promo code if needed, and then you’ll automatically be eligible for the promo.

Our Bookies.com team went on a mission to find the top online casino offers for the UK, and we came up with a list of eight of the best offers. We’ll go into detail about them in the next section.

Even though BetMGM casino is one of the new UK online casinos, the selection of games doesn’t disappoint.

The amount of extra cash and bonus spins depends on how much you deposit. For example, if your first transaction is for £20, you’ll receive 50 bonus spins, while if you deposit £200 or more you’ll get the full allocation of 200.

The online casino welcome bonus for new players at QuinnBet is 50% of your losses back as a casino bonus, plus 10 free spins. While most online casino bonuses have quite high wagering requirements, that’s not the case with the QuinnCasino offer at all - you only need to play through the cashback offer 1x before you’re eligible to withdraw winnings. The offer is very simple to understand: if you’re down after your first day at Quinn Casino, 50% of your losses up to £25 will be automatically credited back to your account, plus you’ll get 10 free spins on Reel Diamonds.

There are plenty of games to look forward to at QuinnCasino. All of the UK’s most popular slots are here, including Bonanza Megaways and Leprechaun’s Luck Cash Collect, and new titles are released all the time. We were also pleased to see that the Mega Moolah games are available, so you could stand a chance at bagging a huge jackpot prize.

Online Casino Bonus With Free Spins - Betfred

Betfred Casino ’s new player offer is definitely the best online casino sign up bonus with free spins. All you have to do is create your new account, deposit and wager at least £10 on slots, and then you’ll be treated to a huge batch of up to 200 free spins. And what’s even better is that you get to choose the bonus you want. You can get 50 free spins on Age of the Gods, 100 free spins on Better Wilds, or 200 free spins on Age of the Gods: God of Storms 2 - it depends on which game you prefer. There are no wagering requirements attached to this offer, so you can go ahead and withdraw any winnings immediately.

Once you’ve used up those free spins, there’s a whole lot more to look forward to at Betfred. From mystery free spins promos, to Comp Points which you can exchange for bonuses, you can really make your money go far. Betfred is one of the top slots sites UK players can join as it has an excellent selection of popular slots including six-figure progressive jackpots, and there’s even a live dealer section with branded tables.

Online Casino Bonus With Promo Code - PokerStars

When you sign up for your new PokerStars account, you’ll get a big bonus of a 100% match up to £500, plus 50 free spins when you use the code FIRST500. Don’t forget to enter this code in the cashier section when you’re making your first deposit of £20 or more, so that you can be eligible for the bonus, as there’s also a poker bonus on the site, which won’t be much use to you as a slots player. You’ll get the offer as soon as you’ve made your deposit, and you can use your free spins on a whole range of games including Book of Dead, Gates of Olympus, Rise of Merlin and Sweet Bonanza. Rather than traditional wagering requirements, this bonus requires you to earn at least two redemption points for every £1 in winnings, if you want to convert it to real money. You can do this by playing games on the site.

If you’re looking for some game suggestions at PokerStars, we’d recommend exploring the full range of games, including exclusive titles such as Pirot 3 and Galina’s Bounty, or brand new slots like Sweet Bonanza 1000 and Kingfisher.

Online Casino Bonus From Top Brand – bet365

As bet365 UK is a household name all across the world, you shouldn’t be surprised to hear that the welcome bonus is just as good as the brand’s reputation. It couldn’t be more straightforward - all you need to do is make a deposit of £10 or more, and select the “claim” box within the cashier section to be eligible for your offer. Once you’ve staked £10 or more on qualifying slot games, you’ll receive 100 free spins to use on the popular games Book of Horus, Eye of Wukong, Sizzling 7s Fortune, or King of the Klondike.

There are tonnes of jackpots like the six figure Age of the Gods series, and you can even try your hand at casino classics in the live dealer section.

Types Of Online Casino Welcome Bonus Offers

You’ve probably heard of a deposit match and free spins, but there are lots of other types of online casino bonuses out there, like these:

Free Spins

There are two different types of free spins offers that you might encounter at online casinos - no deposit free spins, and bonus spins. The only difference is that you need to make a qualifying deposit to claim a bonus spin offer. Free spins are generally restricted to use on just a few games, and even if you’re not familiar with that particular slot, they’re still worth claiming, as you’ll get the chance to try out slots you might not have played otherwise.

Free Chips

Free chips are basically the live casino equivalent of free spins or bonus credit. Many casino offers are only valid on slots, so finding a free chips offer is huge if you’re a live casino sites fan. Depending on the offer, you might be able to use it on games of your choice, or you might need to play specific games, or specific tables.

Deposit Match

The vast majority of online casino welcome offers take the form of a deposit match. These offers are really easy to understand and claim - all you need to do is sign up for your account and make a qualifying deposit, and you’ll get your match in the form of free casino bonus money to use on a wide variety of games. A deposit match offer is a lot more flexible than free spins, as you’ll be able to use it on more games, but these offers also come with T&Cs like wagering requirements.

Bonus Credit

Bonus credit is usually awarded as part of a no deposit bonus. You usually don’t need to do anything to claim your bonus credit, and it will be awarded as soon as you’ve signed up and logged into your account for the first time. Bonus credit can generally be used on a whole range of games, so you’ll have the freedom to choose the slots you like best. 

No Deposit Offers

What could be better than a no deposit offer? These bonuses are exactly what they sound like - they give you access to something for free before you need to make a deposit. No deposit bonuses aren’t that common, even at the best UK online casinos, and they also tend to be less generous than deposit bonuses, but they’re absolutely still worth claiming. A no deposit offer is totally risk-free, as you don’t need to spend any money at all to get it. Depending on the casino, you’ll either get no deposit free spins, no deposit casino credits, or no deposit free chips. Make sure you check the T&Cs, as no deposit offers can come with steep wagering requirements.

Casino Promo Codes

While many online casino bonuses are awarded to you as soon as you either sign up or meet certain criteria (like depositing a minimum amount of money), other promos require you to use a special code to claim the offer. These bonus codes aren’t usually difficult to find. For example, we might have them listed for you here at Bookies.com, or you might find them on the promos page of the online casino website. Depending on the type of promotion, you might have to enter the code during the registration stage, or within the cashier section when you’re making your first deposit. If the offer you want to claim requires a code, it’s vitally important that you enter it at the right time, as you might not be able to go back and do it later, and then you’ll miss out.

Casino Loyalty Schemes

If you’re a brand new player at an online casino, you’re probably most interested in the offers you’ll get immediately, but most UK casino sites also have plenty of bonuses for regular players. Loyalty schemes generally allow you to build up points based on your gameplay, and then you might move up tiers, to become a top level player. Depending on your loyalty level, you might get enhanced promotions like bigger deposit matches, or more regular cashback, and some online casinos also allow you to trade any loyalty points you’ve accumulated for even more bonuses.

How We Review Casino Bonus Sites

Before we recommend an online gambling site to you, we really put it through its paces. Believe it or not, there’s a lot more to it than just checking which site has the best online casino welcome bonus. Luckily, our experts at bookies.com really know their stuff, and they’re on top of exactly what makes an online casino great.

The first thing we look for is a safe and secure experience. Any casino we recommend will be licensed by the UK Gambling Commission, which means that it’s legal for UK players. We also ensure that the site uses encryption technology to protect your personal and financial data. We look for a good range of safe and convenient payment methods like bank cards, e-wallets, and prepaid cards. We even look for Apple Pay casinos and PayPal casino sites. We’re a lot more likely to recommend an online casino that offers fast withdrawals in just a few hours, or even instantly.

One of the most important factors we consider is the game selection. We like to see a range of at least a few hundred slot games, from major providers like Pragmatic Play, NetEnt, and Games Global (formerly Microgaming). Bonus points if there are progressive jackpots like the Mega Moolah titles! In addition to slots, we like to see a strong range of live dealer games and classic table games.

All games - plus the overall site experience - should be optimised for mobile play, whether that’s via a downloadable casino apps, or just through the mobile version of the website. Customer support is also of utmost importance, so we’re a lot more likely to recommend an online casino if there are multiple channels like email and 24/7 live chat, available across all devices.

Finally, yes, of course we look at the actual bonuses. It’s not enough that an online casino gives out a big deposit match - we also comb through the T&Cs to make sure that the wagering requirements and win limits aren’t too restrictive, and that there are no conditions that are totally out of the ordinary. Beyond the welcome bonus, we also look at the regular offers like reloads, tournaments, and free spins bonuses, plus we assess the loyalty and VIP programmes.

How to Find the Best Online Casino Offers in the UK

There’s one sure-fire way for you to find the best casino bonus sites in the UK: browse our list here at Bookies.com! We’re always on the lookout for new online casino bonuses, and as soon as one launches, we’ll be sure to update this page with all the info. You might want to bookmark this page so that you can keep coming back regularly, to see which online casinos we recommend.

The great thing is that we don’t just review the offers of existing online casinos. We understand that UK players are inundated with new casino sites opening up all the time, so we make sure that we take a good look at all of the newly launched sites, to see if any of them fit our criteria for the best casino bonuses. You’ll often find attractive offers at newer online casinos, as they might lack the brand reputation of older competitors, so a great way to attract new and loyal players is by offering enhanced bonuses. But don’t worry - before we recommend a new online casino, we’ll always make sure they’re totally legit.

How To Spot The Best Online Casino Offers in the UK

There are loads of good online casino offers for players in the UK, so how can you tell which are the best? It’s not exactly easy, but there are a few guidelines you can follow to make sure you spot the best offers.

The first thing to look at is the size of the bonus. Of course, you’re going to be more drawn to a deposit match of 100% up to £200, than you are to an offer of 25% up to £100. But it’s important to remember that the bigger the bonus, the stricter the T&Cs tend to be.

We’d advise you to check the wagering requirements before you claim an offer. Ideally, you’d be looking for no wagering requirements whatsoever, but offers like that are really hard to find. So look for cashback offers that only have 1x rollover, or deposit matches where you need to play through 30x rather than 60x.

You should also look at the game restrictions. The best bonuses don’t limit you to which games you can play, and allow you to use the free casino cash across the site. For keen live casino fans, it’s even harder to find a good offer, to make sure your bonus can be used on live dealer games, and that they contribute towards wagering requirements.

If you’re claiming a free spins bonus, you might want to look out for one that gives you the choice of a few different games, so that you can play one you know and love. It’s also worth checking the spin value, as some free spins promos hand out really low value spins, and they might not even be worth claiming.

And finally, you should consider whether there are any win limits applied to your bonus. The best bonuses have high win limits, for example you might be able to cash out £100 or even £200 from the bonus. Offers which aren’t so good might limit your winnings based on previous deposits, or give you a low limit, like £10.

Why Sign Up to Multiple Casino Bonus Sites?

So far, we’ve spoken a lot about how to spot the best online casino bonuses out there, but if you’re struggling to make up your mind, don’t worry - you can claim more than one bonus.

In the UK, there’s no limit on the number of different online casino accounts you can hold. Of course, it’s important to remember that you should always gamble responsibly, so you might want to limit yourself to just a few accounts.

Having an account at multiple sites can have a lot of different benefits, with perhaps the most important one being the bonuses. Different online casinos have different welcome bonuses, so by having multiple accounts, you might be able to snag a deposit match at one casino, and free spins at another one. The same goes for regular promotions. If you sign up for marketing emails from your chosen online casino sites, you can make sure you’re always kept up to date about offers, so that you can log in and claim any that catch your fancy.

Before you sign up at multiple sites to bag the welcome bonuses, it’s a good idea to read the T&Cs in full first, as some online casinos only allow you to claim one bonus across the whole group of sites.

Of course, having multiple online casino accounts isn’t just about the bonuses, it’s also about the game selection. If you stick to just one casino, you’ll only ever be able to play the games they have. While some of the best online casino sites might have a better range of slots, others really focus on live casino games, and others still have an attached sports betting section. Having multiple accounts allows you to swap between them, so that you can take advantage of a much better variety of games. 

How to Claim The Best Online Casino Welcome Bonus Offers?

Now that you’ve read most of our guide to the best online casino bonuses, you’re probably ready to create your account and get stuck in. Don’t worry, claiming a welcome offer isn’t a long or arduous process, and you’ll be spinning the reels on your favourite slot games before you know it. You can follow this quick guide to signing up and claiming your offer:

1. Choose your online casino. You can do this by reading our reviews on this page at Bookies.com, and selecting the bonus that looks most appealing to you.
2. Click on a link on this page. You’ll want to sign up via a link from Bookies.com, so that you’ll be eligible for the best possible bonus.
3. Create your account. You’ll have to provide some details like your name, address, date of birth, and the email address and password you’d like to use to log in.
4. Enter the promo code if necessary. This step isn’t always needed, but if there’s a promo code required, you should add it now.
5. Make your first deposit. Always check to see what the minimum deposit amount is to claim the offer, then head to the cashier and make your first deposit.
6. The bonus cash or free spins should appear in your account immediately.
7. Head to the games lobby, choose your favourite slot, and start spinning. 

One thing to note is that the account verification procedure is strict at UK online casinos. This is nothing to worry about, it’s just a feature that makes your experience totally safe and secure, and ensures that minors are protected against gambling. You’ll have to be at least 18 years old to gamble in the UK, and when you first create your account, the casino will attempt to verify your details automatically. If that can’t be done, you’ll be asked to submit copies of your photo ID (like your passport or driving license), and proof of address (utility bill or bank statement). This will have to be done before you can log in for the first time and get your welcome bonus.

Online Casino Offers Terms & Conditions

It’s safe to say that every single online casino offer comes with terms and conditions, and welcome bonuses are no different. It’s really important to read the T&Cs in full before you claim any bonuses, especially ones that require a real money deposit first. Chances are, if an offer seems extremely generous at first glance, it might come with some restrictive T&Cs, which can limit the amount of money you can win.

The first thing to note is that in general, no deposit bonuses have more conditions attached than deposit bonuses. It makes sense when you think about it - of course an online casino wouldn’t want to give you a huge bonus and give you the chance to have a massive win before you’ve spent any money.

One of the most important terms which you’ll come across pretty much every time you claim an online casino offer is wagering requirements. To put it simply, wagering requirements are how many times you have to play through the bonus (or deposit plus bonus, or free spins winnings) before you can withdraw. For welcome offers, wagering can be up to 65x, but sometimes you’ll get lucky and there’s no wagering attached to a promo.

Free spins bonuses are usually limited to use on a few games, but deposit match offers can have game restrictions too. For example, you might not be able to play high RTP slots, or progressive jackpots with bonus money, or they might not contribute towards wagering requirements. The same goes for table games and live dealer games - many bonuses exclude them. There’s also usually a maximum bet amount that you can place with an active bonus, for example it might be £5, or it could be a percentage of the bonus amount.

But game restrictions and wagering requirements aren’t the only conditions on casino welcome bonuses. There might also be a maximum win limit set for a promo. This could mean you’re only allowed to withdraw a certain amount per free spin, or there could be a cap (for example £100 or £200) on how much you can win with the offer.

Some online casinos restrict the welcome offer to certain payment methods only. For example, while bank cards are usually accepted, more often than not you can’t claim a welcome offer with a Skrill or Neteller deposit. In the majority of cases, you’ll also need to deposit at least a certain amount of money to claim the offer. This is usually £20, but it can sometimes be more.

Are Online Casino Offers Legal in the UK?

The answer to this question is very simple - yes, online casino offers are legal in the UK. But this does come with one caveat: you have to always make sure you’re playing at a licensed UK casino site, which is approved by the UK Gambling Commission. It’s not legal for unlicensed sites to accept UK-based players.

If a casino holds a license, it’s totally legal for you to sign up and claim an offer with them. Of course, it’s important that you always follow any T&Cs associated with the offer. For example, you’ll need to be aged 18 or over to claim an online casino welcome bonus in the UK, and you may need to provide your ID and proof of address documents during the sign up stage. You’ll also only be able to claim one welcome bonus per online casino (this sometimes applies to you as an individual, or to your whole household), and if you’re found to be committing bonus fraud, your online casino account might be blocked.
