Best Casino Bonuses and Offers for UK Players in 2022
Casino bonuses are the best way to discover new sites and play real money games online. On this page, you find all the best online casino bonuses for UK players with easy-to-understand details about what makes them special.
Before we get to the list and we look at what are the different UK casino bonuses to claim, let's look at the most important elements to consider when choosing a casino offer.
- All casino sites apply different terms and conditions to the casino bonuses they offers. Depending on factors like the wagering requirements, the cap on winnings, and games included in the offer, some bonuses can be better than others — even when they offer the same amount of free money or free spins.
- The games included in the promotion impact the bonuses, massively. Depending on what you can use the casino bonus for, an offer can be best for slots players or for table games players. Given only a few casino bonuses let you play live dealer games for free, you need to read the fine print if that's what you want to do.
- Payout times and support matter, too. There's no point in using a casino bonus to play real money games if you can't cash out your winnings. The best offers are the casino bonuses that let you keep what you win.
- [B]All the offers on this page come from websites licensed by the [I]united Kingdom Gaming Commission[/I] (UKGC). We believe in fair and safe gambling, and playing on legal UK casino sites is the only way to make this happen.
On this new CasinoSmash guide you'll learn how to recognise the different bonus types on offer at online casinos in the United Kingdom, how to read the terms and conditions, and what are the top casino offers based one the games you like to play.
A Note about Responsible Gambling
Gambling games can be addictive and they are potentially destructive for those who play for the wrong reasons. If you think claiming a casino bonus is a good way to get away from the stress of your daily life, think again.
Playing for financial gains is also not a good idea. The house edge is never in your favour and despite the casino offers you find online or the strategy tips you apply to your games, the odds will never be in your favour.
Here at CasinoSmash we believe in fair and responsible gaming. Since we like to put our money where our mouth is, we even co-founded RAiG, an association that brings together affiliate sites like ours and sets best practices to promote gambling in an appropriate and never misleading way.
That's why we are here to tell you that you should always gamble responsibly, even when you use a casino bonus to play for free.
Caring about the money you spend on the games and being financially responsible about it is the only way to go to keep gambling fun and enjoy all the casino offers on this page.
Bookmarking pages like GamCare and the BeGambleAware website is an excellent +EV move for you. Keeping these websites handy will help you keep your gambling habits under control and get the help you deserve, whenever you need it.

What Are the Best UK Casino Bonuses?
A good casino bonus is an easy and inexpensive way to play games online and discover what casino websites have to offer.
We spent over a month on research, spoke with marketing managers at more gaming websites than those you see in the list, and tested all these offers to see how they really work.
This allowed us to identify what we believe to be the best casino bonus you can claim right now: the PartyCasino new player bonus.
It offers the best combination of free spins on Starburst, a lower-than-average wagering requirement, and access to even more promotions after that.
Best Casino Bonus for UK Players: PartyCasino
50 Free Spins on Starburst
PartyCasino is our go-to casino site for slots players. Why? Because they combine a great selection of games with a generous welcome offer to enjoy 50 free games on Starburst.
- 25 free spins to play Starburst
- 10x wagering requirement
- Impressive selection of games
- Use the 'Free Spins Prize Wheel' for more bonuses
18+. New depositors only. UK residents only. Minimum deposit £10. Free Spins are valid only on Starburst and expire in 7 days. 10x wagering apply. Certain deposit types are excluded. T&Cs apply.
PartyCasino is one of the top gaming brands in the world and one of the most popular online casino sites in the United Kingdom.
The welcome bonus is easy to claim and has simple terms and conditions attached to it. Considering how popular the Starburst slot machine game is in the UK, we believe this offer will make a lot of you very happy.
When you register on PartyCasino, you receive 50 free spins on Starburst as soon as you deposit £10 or more. To use the bonus you need to activate the free spins via the 'My Free Spins' section of your account within 7 days.
Each free game is worth £0.10 and there is no cap on winnings, meaning what you can turn the 50 free spins welcome bonus into is an affair between you, the Starburst game, and Lady Luck.
PartyCasino applies a 10x wagering requirement to the winnings generated through the welcome bonus. This is one of the lowest you find in the UK casino industry today and it gives you great chances to keep what you win.
The only flaw of this bonus concerns the payment methods included in the promotion. Make sure you do not use PayPal, PaysafeCard, LuxonPay, Skrill1Tap, Neteller, Instandbank (Trustly), Apple Pay, PCard, MuchBetter, or a credit card as these payment methods are not eligible for the promotion.
What's special about PartyCasino is that this is only one of the many offers on tap. If you are interested in even more free spins, make sure you don't miss the site's 'Free Spins Wheel' promotion.
Best No Deposit Bonus Offer: 888Casino
£88 FREEPLAY No Deposit Bonus
888Casino offers one of the most generous welcome bonuses in the UK, with £88 in FREEPLAY available to all new players who register on the website.
- Free £88 no deposit bonus
- 50x wagering requirement
- Lots of exclusive and jackpot games
- No promo code needed
New players only • Claim within 48 hrs • 14 day expiry • FreePlay (FP) wins credited as bonus & capped at £10, excl. JP wins • Valid for selected games • Bonus wins capped at £500, excl. JP wins • Pre-1st deposit only: Bonus wins & max redeemable amount capped at £100, excl. JP wins • 50x wagering – req. vary by game • Bonus expires in 90 days • Withdrawal restrictions, T&Cs apply.
Although you might not get the chance to use your bonus on a classic slot like Starburst, the 888Casino bonus is another offer we believe is going to surprise a lot of UK casino players.
Open to players in the United Kingdom and Ireland, this casino bonus is the most generous no deposit offer on the market - even despite the £500 cap on winnings included in the offer's terms and conditions.
Register a free gaming account via this page on 888Casino to receive their spectacular £88 FREEPLAY bonus with no deposit needed.
The bonus is valid on selected games and the wins, as mentioned, are capped at £500. The reason we rank this bonus lower than the PartyCasino one is the 50x wagering requirement applied by 888.
With 90 days to clear the bonus, it might be a bit difficult for most players to clear the playthrough requirement and request a withdrawal.
A deposit of £20 or more triggers the second welcome offer at 888Casino, with the site doubling the amount of your deposit for up to £100 in bonus money. The wagering requirement applied to this bonus is 30x.
Best Casino Bonus for Slots Players: Casino.com
200 Free Spins and up to £100 on Deposit
Casino.com is an industry-leader gaming platform with a top choice of slots, table games, and possibly the best live casino platform in the UK. Their deposit promo is a value packed-offer that combines bonus cash and free spins.
- 200 free spins on Age of the Gods games
- Up to £100 in bonus money for all other games
- 20x wagering on free spins, 40x on bonus funds
New customers. Min deposit £20. 40 free spins on first deposit. 160 free spins after first deposit (20 per day). Max win £100. 20x wagering. Deposit bonus 40x wagering. Expires 30 days from issue. Eligibility, game, platform, payment restrictions, and T&Cs apply.
The best bonus to play slot machine games online is the one at Casino.com and is available to all players in the United Kingdom and Ireland.
Everything happens right after your first deposit, with the site giving you 40 free spins and a 100 percent deposit match for up to £100 in free bonus money as soon as you deposit £20 or more.
You will receive also an additional 20 free spins per day for the next eight consecutive days for the impressive total of 200 free spins!
While we understand that a £20 deposit isn't cheap, we find this to be a value-packed offer as the minimum deposit gets you an additional £20 in bonus money and 200 free spins on selected games.
The casino bonus is valid to all the players who register a new account on the website. To claim this offer, you must be 18 or older.
What makes this a great casino bonus for slots players is also the fact that the free spins come with a 20x wagering requirement (the multiplier raises to 40x for the bonus money).
There's a thirty-day expiry time connected to this deposit bonus offer - so you'll need to be relatively quick once you get it.
Other Recommended Sign Up Bonus Offers
The three online casino bonus offers above are not the only options to play casino games for free, especially if you don't mind the idea of making a deposit.
On most online casinos, your initial deposit is matched with a bonus - and while the minimum deposit may vary between £5 and £10 depending on the gaming sites, the offers that follow are some of the best deposit and no deposit bonuses UK players can claim this year.
LeoVegas Casino Bonus
Did you know the Book of Dead game is the second most-played slot machine after Starburst? The welcome bonus at LeoVegas is the perfect offer to enjoy this super-popular game and join Rich Wilde in his treasure hunt.
You get 10 free spins with no deposit needed as soon as you complete the registration process on the website. The free spins are wager-free meaning you also get to keep what you win.
Bear in mind we are talking about 10 no deposit free spins worth .10p each, so you shouldn't see this bonus as a chance to become a millionaire but rather a way to play free games on one of the top slot machines out there.
It's also a way to get your foot in the door at LeoVegas and get your place in line for their first deposit bonus offer. Deposit £10, £25 or £50 within seven days from creating your account and the site will give you up to £100 in bonus money (play through requirement: 35x) and 20 additional free spins, again with no wagering requirements.
777 Casino Bonus
Coming from the same family as 888Casino, 777Casino is also a reliable, safe, and generous website with lots to offer to new players.
Right now, their welcome promo includes a two-part offer that combines a no deposit and a post-deposit bonus.
Register via CasinoSmash to receive 77 no deposit free spins on Ray of Light, Lucky Orbs, Noche de los Muertos, and Millionaire Genie. The free spins need to be claimed within 48 hours, expire in 14 days, and lead to wins credited as bonuses that are capped at £10.
If you go for a deposit, the casino promo code WELCOME777 is your best shot at extra bonus money. This bonus code triggers a 100% match offer that gives you up to £200 instant FREEPLAY.
The terms and conditions of the deposit bonus include a cap on winnings set at £500 and a wagering requirement of 30x.
BetVictor Casino Deposit Bonus
There are some flaws that pushed us to keep the BetVictor Casino offer out of the top three best casino bonuses, but this doesn't mean you should not consider playing at this great gaming site if you don't already do.
Players in the UK and Ireland get a special package that gives you the chance to win up to £750 — making it one of the (potentially) most lucrative welcome offers in our selection.
The bonus at BetVictor doesn't multiply the initial deposit with a match bonus - but brings something different to the table instead.
New players who register a gaming account on the BetVictor Casino website, make a deposit and play real money games are entitled to 100 free spins and £30 in cash money.
To activate the promotion simply register via the links on CasinoSmash, make a deposit, opt-in, and play. If you wager £10 within seven days from opening your account you will get three £10 bonuses for selected games with up to 40x wagering plus 100 Free Spins.
The bonuses expire in seven days and the 100 free spins have no wagering!
Seven Cherries Casino Bonus
Despite Seven Cherries Casino not being one of the best-known gaming sites in the United Kingdom, it is an interesting one for slots players. Every new depositing player starts on the site with up to £10 in bonus money and 10 free spins on Starburst.
A deposit of £10 is enough to trigger the Seven Cherry Casino welcome bonus and give you the chance to play some extra games for free.
The bonus is valid for UK players only and carries a 40x play through requirement.
Why you should trust us
To get an idea of what makes a good casino bonus in the UK —including how to claim the offer, how to turn the bonus money into free spins, and how to withdraw your winnings — our editorial team interviewed players and key figures in the industry.
We also combed through a bunch of casino bonus guides, casino forums, complaint systems, and customer reviews to identify some of the basic requirements, as well as a few dealbreakers.
Giovanni Angioni, who researched and wrote the 2018 first edition of this guide, is the Head of Gaming at Oddschecker Global Media and he has also written guides to poker bonuses and the best gaming sites. In 2013, he was nominates 'Media Person of the Year' at the European Poker Awards.
Types of casino bonuses: what's the difference between a deposit and a no deposit bonus offer?
When it comes to the types of casino bonuses available, top casinos usually supply the best of both worlds - starting with a smaller no deposit bonus, and then moving you on to a meatier cash deposit bonus, more commonly referred to as a welcome bonus.
Depending on the casino, some welcome bonus packages can be worth thousands of pounds. To help you navigate through all the offers on our guide and all those you might yourself, this section helps you understand how casino bonuses work and how to find the best online casino bonus offers in the United Kingdom.
- Welcome bonuses and sign-up bonuses are the offers that online casinos give to new customers after they register an account for the first time. Since these are the bonuses that will convince you an online casino is worthy of your time and money, these offers tend to be the best online casino bonuses around.
- No deposit bonuses give you free money or free spins on registration without you needing to make a deposit first. Despite the small amount of free cash and free spins provided, these are the most popular form of casino bonuses. Our pool of experts ranked no deposit casino promotions like the 'top casino bonuses' for beginners.
- Deposit match bonuses are the most common form of online casino bonuses. Nearly every online casino out there offers a sign-up bonus of this kind to play casino games. To trigger a deposit match bonus you need to register a gaming account and make a first deposit. If this meets the min deposit requirement set by the offer's terms and conditions, you get the bonus money.
- Free spins are all slots players think and care about. These offers can include deposit free spins (triggered by your first deposit) or no deposit free spins (yours on registration) to play different slot games. Slots bonuses are tricky because online casinos tend to limit the number of slot games you can use the free spins on - 'forcing' you to stick to some titles. One of the most common types of slots bonuses is the 100 free spins on Starburst offer.
- Reload bonuses are often considered to be amongst the best casino bonuses because they can provide huge value to players. We do not list any reload bonuses on this page because these are match deposit bonuses that happen on deposits subsequent to the first one. They work exactly like the regular welcome bonuses calculated on the first deposit.
- Cashback bonuses are offers that see players receiving a percentage of the money they lost on casino games back to their account. Most casinos pay cashback bonuses in bonus funds, while a small number of them pay these offers in real cash.
- High roller casino bonuses are the offers for the biggest spenders. These often require six-figure deposits and are built around the needs and requirements of the players. The best way to secure one of these exclusive bonuses is to request them to a gambling site prior to making a deposit.
Players who don't have millions to spare need, at the very least, an online casino bonus. The difference between deposit bonuses, free spins, and no deposit bonuses to play casino games is sometimes confusing.
An offer that gives you bonus spins might come with an attractive bonus amount — and yet it might not be for you as it wouldn't let you play video poker, live casino games and more for free.
If you have specific preferences, you need to find online gambling sites that offer something that fits your needs and preferences. Live casino players, for example, might need a cash reward coming from a welcome bonus that gives away no less than £500 in bonus funds.
An effective free spins bonus should keep you busy on slot machine games for a good while. Keep an eye out for new casino bonuses, and make a note to visit this page frequently (ideally, once a month).
How we picked and tested the online casino offers
The most important aspect of a top casino bonus is whether you like the games you can play with it and you are comfortable with the bonus wagering requirements. We searched UK casino bonuses and bonus codes that would appeal to the largest variety of players, focusing on different casino games, the preferences of video poker players, live casino players, and slots aficionados.
We based our decision partly on the advice of online gambling specialist and Head of Gaming at Oddschecker Global Media Giovanni Angioni, who told us that a lot of people want a casino bonus to have a "Las Vegas-like" experience rather than playing "a few free spins on a random slot machine."
"If that's your preference," Angioni explained, "we recommend choosing exclusive casino bonuses that do not apply restrictions to the games you can play and with low wagering requirements."
We focused on new customer offers at legal online casinos, even if these tend to be a bit less flashy compared to the match deposit offers promoted on off-shore gambling sites. We did so because we believe in fair gambling and we want our players to be always protected and safe.
For most of our picks, we considered online casino bonuses that do not require a bonus code and that offer more than £1,000 and 100 free spins. For our upgrade pick, we expanded our search to include exclusive bonuses that can net players sums in excess of £5,000. Unless you're going for a specialized online casino bonus, there's little reason to spend more than this on casino games.
The experts we spoke to agreed that the bonus spins and welcome bonuses picked to prepare this curated shortlist are ideal because they are easy to claim and they cater to a wide variety of players, and we also think they are a great option for anyone looking for a little extra to play casino games.
Although all welcome bonus promotions are subject to terms and conditions that make cash or bonus spins winnings sometimes hard to cash out.
To find the best casino bonuses to test, we scoured online gambling sites and guides for the most popular and best-rated promotions for new players. This search included big names like 888Casino, PartyCasino, Casino.com and more as well as specialized gambling forums and user-centred platforms like Reddit and Quora.
We tested over 50 contenders for our initial review and tried 15 additional online casinos as possible upgrade picks for the most recent round of testing. Although we don't think you need to spend more than £10 to trigger a good welcome bonus, there are a few pricier options available, especially if you are in the market for high roller bonuses or you want something bigger than your regular mobile casino bonus.
In our initial tests, we checked the precise process required to claim the welcome bonuses and verified whether a casino bonus code was needed or not. This allows us to check for any deviation from the advertised offers. We then claimed each bonus ourselves. At this point, we checked for discrepancies and verified whether the online casino we used gave us the max bonus funds and max bonus spins we were promised.
We then played games to assess factors such as game choice and ease of use of both the bonus funds and free spins. We also looked closely at how the casinos handled our bonus winnings to check for procedural issues, sudden changes in the casino bonus terms, and delays of any kind.
New Customer Offers v Bonuses for Existing Players
All the offers on this page are designed to welcome new customers to online casino sites and can be claimed only once. If you already have an account on a website, you should look into their 'existing customer offers' to discover what the casino has planned to keep you interested in their games.
Cashback bonus offers and free spins are the most common type of bonuses for existing players. If you don't see any existing customer offers you like at a casino, reach out to their customer support and make your voice heard.
Most online casinos will go to great lengths to accommodate the requests of their players and they will be open to creating custom-made exclusive bonuses just for you.
A few notes on the Terms and Conditions
All casino bonuses will include terms and conditions of some kind. That's why it is important to do your research and check the T&Cs thoroughly before committing to an online casino sign up bonus.
No matter how extensive the terms and conditions of a bonus offer might be, there are always a few core elements that you should be looking out for. These include the expiration date of the bonus offer, any wagering requirements and winning caps.
The time period given on a bonus offer or wagering requirements can vary greatly, so it's important to check these thoroughly to avoid forfeiting winnings.
You may also find that the casino will restrict you to certain games only during the use of the bonus offer, so it's important to note this information as well.
Wagering requirements: how to convert bonuses into real money
Most welcome bonuses include wagering requirements that players must consider when redeeming a promotion. The wagering requirements (often referred to as play-through requirements) refer to the number of times players needs to wager the bonus amount before they can cash out their bonus winnings.
This requirement is usually presented as a multiplier, which most online casinos set anywhere in between 20x and 50x. What this number means is that you will need to bet your bonus amount 20 or 50 times over before you can withdraw any winnings.
Cap on winnings: here's how much can you actually win
Nearly all deposit bonuses come with a limit to how much money you can win with them. This is usually referred to as 'the cap on winnings.' Although there are a few exceptions that do not apply any limits to their promotions, most casinos will keep this amount high enough to keep you engaged but reasonably low to prevent you from nailing the biggest progressive jackpots for free.
Bonus funds and bonus spins are usually connected to a limited selection of games. These are always specified in the terms and conditions of an offer. For your convenience, we also report these details on the casino reviews we publish here on CasinoSmash so you don't need to sweat too much to understand what is allowed and what isn't.
Frequently asked questions about free casino bonus offers
What are online casino bonuses?
Online casino bonuses are offers created to give rewards to new and existing players. These can include free money, free spins, cashback offers and more.
Can casino bonuses be used on mobile casino apps?
Yes, they can. You'll find a number of online casino apps with sign up bonus offers for new players. Depending on the provider, the offers will remain consistent across mobile and desktop platforms, while others may offer promotions that are exclusive to the mobile app.
Are bonuses just meant for new players?
No, they are not. While it is true that welcome bonuses are targeted at new players, you'll find plenty of top online casino bonuses for existing players as well. Once you've signed up with a reputable casino, you can enjoy their welcome bonus and, once you're done with that, you can enjoy a number of ongoing casino promotions, bonuses, VIP rewards and more.
What are the best casino bonuses?
The best casino bonuses will depend largely on your current needs or goals. For example, if you are a new player, the best online casino sign up bonus offers will be what you are looking for, while seasoned pros may be more tempted with free spins or multipliers that can boost their bankroll.
Can you turn your casino bonus into real money?
This depends on the casino bonuses that you go for. If the bonus is a cashable bonus, then you can turn your bonus into real money once you've completed all of your wagering requirements.
What online casino games can you use casino bonuses on?
It depends on the casino bonus. While some can be redeemed on any game that you like, others may only be applicable to select slots or a specific game range. Check the T&Cs of any offer before redeeming.
What is the expiration date on casino bonuses?
The expiration date on casino bonuses refers to the end of the period at which a promotion can be redeemed. Players are unable to benefit from a bonus past this date, and may forfeit any winnings they've accrued over this period unless the full wagering requirements are met.
