Here’s one bonus code you can’t go without. I find Regal Wins is an epic place to play, especially when they throw in £20 of bonus funds just for making a first deposit of £10. There's even 100 spins dished out for good measure. Simply enter RW100 when depositing your cash at the cashier.

New to Pokerstars? A superb double deal is waiting for you at this casino – a 200% deposit match of up to £300 plus free spins on a dozen slots from top providers.

❗ No codes needed for any of the promos below! Just click the link to signup and claim!

Sometimes, you may come across a casino bonus code in the offer terms, but online casino sites rarely use coupons these days. Usually, no special code is needed to claim any offers listed. So don't just narrow your search to promos with codes attached! 

Often, sites will just give you the welcome package right away, all as part of the sign up process. It's easier for everyone that way. You don't end up forgetting to enter a casino promo code at the right time, and then the site doesn't have to deal with your customer service request to get that fixed.

If you do find active bonus codes for casinos that you like, just copy and paste them when and wherever they ask you to. Some online casino bonus codes in the UK need to be entered when you sign up, while others are required when depositing. Just do what the site says to get all the bonuses and promos.

Code or no code, you usually need to add money to your account to get bonus funds or spins. I've listed some of the best £10 deposit casinos on this page since this is a common minimum deposit amount, and you'll have a tenner handy if you plan to get the casino coupon codes from these sites.

Once you're signed up and play regularly, the casino will send existing player bonuses straight to your account - or at least inform them of you by email or SMS. There might be a code to copy, or you may be given a link. This is the case for things like weekly spins and birthday bonus casino bungs.

I’d also suggest keeping an eye on a site’s promos page for any new casino offers. While most casinos send exclusive bonus codes direct to you via email or SMS, others expect you to go looking. 

Codes sent you are likely to be single-use, specific to you, and time limited. While codes on the promo page will be generic. Available to all players, in other words. 

Most bonus codes for existing players open doors to deals like reload bonuses, free spins promos, or even a rarely-spotted no deposit casino bonus.

I mentioned, didn't I, that promos at online casinos come in a fair few shapes and sizes? You can see from the offers I've selected above that sites take different approaches. Whichever suits you best depends on what you like to play, how often, and how much you usually wager.

If slots are your go to game, you're bound to be out for a slots promo code. These bonuses usually take the form of free spins. You'll get a certain number of spins added to your account in return for signing up to a new site and making your first deposit. Sometimes sites will give you the spins without any deposit needed, but this is pretty rare these days. Any deposit requirement is usually pretty small though, in the region of £5 or £10. And don't forget your spins are ‘free’ because they're added on top of any money you deposit. So all of that £10 is still yours to play with - including on slots. 

When you use promo codes for slots, you'll usually be limited as to which games you can use the giveaways on. It might even be one singular game title - though for the most part it'll be a game any of us seasoned slot players are familiar with. There also might be requirements to meet before you can withdraw anything you win off your prize spins.

Deposit match deals are here to boost your bankroll. When you sign up new and use casino coupon codes of this type, the site will agree to match your initial deposits at a certain percentage and up to a certain cap. This is often on the first deposit you make only, but I've seen sites spread the promo across the first few. 

Say I entered a promo code for a deposit match at 200% of my first deposit, up to £100. I then add £20 at the cashier section of the site. In return, I get 200% the value of this deposit on top, which equals an extra £40, leaving my bankroll at a whopping £60. I could've deposited £30 and I'd have had £90 in total, though there wouldn't be much point going higher, given the £100 cap. 

As ever, conditions do apply - wagering requirements almost certainly so here. That means if I landed a big win, I'd have to bet the value of my initial deposit a certain number of times over before I could withdraw any money.

It's common to see both of the above bonus types bundled into one package. Casinos like to wrap up incentives together under one promo code, particularly for new players. Several of the offers I've listed above offer some sort of deposit match deal alongside a few free spins on a given slot game. 

I really like these sorts of offers – you get the best of both worlds, and it feels like a proper welcome. Always check the terms and conditions, however. That’s where the real difference between the worthwhile and not worthwhile can be found. In particular, keep an eye on wagering requirements. Industry average is around 35x, while I'd personally steer clear of anything 50x or above.

Everything we've covered so far has been about the newbies. So what do you get for showing some loyalty and sticking around? 

The truth is that it varies wildly by site. Some are rubbish at this, and others great. If you aren't seeing bonuses like weekly free spins or free cash drop into your account, I suggest keeping on top of your emails. Sites that do use online casino bonus codes are likely to drop the deets to your email or text you, rather than handing them out automatically. I'd also recommend you keep your eyes peeled on these casinos' socials. They may well throw existing customer promo codes out there on the likes of Instagram, Facebook, and X.

Before you go ahead and use our exclusive casino bonus codes, you should know what you're getting into. You do need to keep a few things in mind. Only when you're clear on these can you know whether a particular bonus is worth your energy. Let me go through in a little more detail.

When using casino bonus codes in the UK, checking you're eligible will save you time and hassle. Most of the offers on this page are for new players only. So if you already have an account at a given casino, you won't be able to claim them.

But all's not lost. Some sites offer free casino promo codes for existing customers, too. If you stick around for long enough, the site may send you special offers directly to your account or email you. If it's been a little while, why not long into your account and see if there's anything waiting for you?

It’s crucial to check the time limits when claiming casino promo codes. That’s because sites are often strict about when and how to use them. Sometimes, you'll need to enter a valid code within a specific window after signing up or depositing, so be sure to read the bonus terms carefully. If you miss the deadline, you might end up losing your bonus. 

Also, remember that any funds you get from bonus codes for casinos usually need to be wagered in a week or so. Very rarely will it just sit in your account forever.

In my experience, casinos are selective as to which games the bonus codes can be used on. In most cases, codes for free spins are restricted to some specific titles, usually big hits like Starburst and Book of Dead. Meanwhile, bonus fund promos can vary wildly in their game availability.  Sometimes it’s one or two games eligible. Others have entire sections of the game lobby available. It really does depend - so this is one bonus term you want to understand clearly.

That's why I'll always tell you to check those terms. Even if the casino allows you to use bonuses on multiple games, it may still restrict some titles. Usually those with a high RTP (return to player) rate. And while you’re at it, check which games contribute 100% towards the wagering requirements.

It's rare for a casino to let you mix and match several bonuses. As a one-off perk for new players, it's unlikely that you can combine UK casino bonus codes with other offers going on at that site. But you can check out codes for other online casinos instead. Compare them to the current offer you’re seeing and make sure you're getting the best deal. And there's nothing stopping you grabbing a great bonus whenever you see it elsewhere - especially if you don't have to part with much or any cash. 

I've listed places you can find 25 free spins on registration with no deposit in the UK. This is a bonus I'd strongly suggest you snap these up while waiting for your preferred site to dish up the goods.

Bonuses are great, but they usually come with some strings attached. You'll usually need to meet specific wagering requirements to cash out your winnings. This can be a real pain. 

The industry average is 35x, which means you'll have to bet the value of your bonus funds 35x over before you can withdraw any winnings leftover. This is certainly doable, and people do take home big sums of cash. Buy wagering requirements on the higher side of average are a real struggle to meet.

You should always check out the maximum withdrawal limit when using a casino promo code. This rule is as important as knowing the time limits and wagering requirements. It tells you the most you can ever win from your bonuses.

If you're using free spins or no deposit bonuses, it's not such a big deal. But it's especially important for deposit matches, where you'll need to decide how much of your own cash to put in.

Let's run through how to use promo codes for online casinos in five simple steps. The process may differ a touch depending on the site. But follow this and you'll be on your way to claiming some of the best bonus codes in the UK.

If you still couldn't spot anywhere to enter the code, come back here and double check that the offer you selected even needs one. Remember that many now don't. But if you're still at a loss, check the casino site for an FAQs section or contact customer support via live chat or email.

And that's it! You can now head for any eligible games and start using your bonus. Whether you're a blackjack aficionado, love the thrill of live titles, or prefer new slots online – the choice is yours.

At Casinos.com, we're a team of casino enthusiasts passionate about sharing the biggest and best tipoffs in the business.

To make that happen, I first check the casino's licence and ensure it meets our strict criteria. Then I look for the bonuses – only the best codes make it here to our lists. These are generally aimed at newly joined up players. So if you're a regular player at online casinos, try our dedicated page for the best high roller bonus in the UK.   

When it comes to finding the best sites, I often prioritise fast withdrawal casinos. We sign up and check that these sites deliver on their promise to make the payout available the same day. And I'll always let you know if they don't. Diversity of payment methods is also absolutely key. Especially now the financial services sector is more varied than ever.

While looking for the best online casino I also evaluate customer service, check terms and conditions, investigate special features like mobile apps, and the overall look and feel of the casino. Once I'm happy with everything, I'll write a detailed review and make the site's biggest promos as easy as possible for you to find.
