1. 888 Casino – Best UK Casino Bonus Overall
New players only | 14-day expiry | Spins valid pre-1st deposit only | Bonus expires in 90 days | Deposit only valid for 1st dime depositor | £20 min deposit | Valid for selected games | 30x wagering requirement | Note that the full T&Cs apply.
- 100% match on up to £100
- 88 bonus spins
- 30x wagering requirement on deposit bonus
- 1x wagering requirement on bonus spins
888 Casino has been offering some of the best casino bonuses around, and today is no different. Their current welcome offer just so happens to be two casino bonuses rolled into one.
The first casino bonus is 88 spins set to 10p per spin that you can claim without even depositing. Winnings from these spins are converted into bonus money with an unbelievable 1x playthrough requirement. After that, your winnings are as good as cash and are ready for withdrawal.
The second part of the bonus is a 100% match on your first deposit up to £100. This comes with a reasonable 30x playthrough requirement.
To claim the deposit bonus, a minimum deposit of £20 is required. Bonus funds expire after 90 days.
It’s also important to note that different games contribute differently to playthrough requirements. Below is a list of 888 games and what percentage of their wager contributes:
- 100% – Video slots & slots, scratch cards, keno, race, arcade, dice, and all other games that do not appear on the table.
- 20% – Pai Gow Poker, Caribbean Poker, triple card poker, and poker table games
- 10% – All versions of blackjack, hi-lo, all versions of roulette, live casino games, power video poker, and video poker
- 5% – Craps
2. NetBet – Best Bonus Spins Offer in the UK
New players only | £10+ Deposit | No e-wallets or prepaid cards | Up to 500 Bonus Spins | 40x wagering on winnings | Note that the full T&Cs apply.
- Up to 500 spins with the promo code “NBWELCOME500”
- 40x playthrough requirement for real casino bonus spins
- 50x playthrough requirement for Vegas casino bonus spins
If you’re looking to cash in on a tonne of bonus spins, NetBet has one of the best casino bonuses around. Use the “NBWELCOME500” code with your first deposit for 50 bonus spins immediately. The rest of the spins will be credited to your account randomly over the next 6 days.
After your 1st deposit, you’ll want to log into your account several times a day to ensure you don’t miss any other extra spins. NetBet’s terms and conditions state that the bonus spins are dropped in lots of 25 up to 3 times a day, and once logged in, you should see a pop-up where you can deny them if you really want to (yeah, right).

The bonus spins will be usable on select games in NetBet’s “real” casino and their “Vegas” casino, though it’s important to note that the two casinos have different wagering requirements.
The main casino’s 40x playthrough requirement is a little steeper than we like to see but beats out the 50x playthrough on their “Vegas” casino, where they seem to hide all their jackpot slots.
Each batch of spins will need to be used up within 48 hours of being issued, is only available on eligible games, and declined/unused bonus spins will be forfeited.
A minimum £10 deposit is required, and deposits must be made with a debit card. Deposits made with prepaid cards or e-wallets are disqualified from this promotion.
3. Casino.com – Best UK Casino Bonus for Slots
New customers only | £20 min deposit | 40 spins on first deposit + 20 per day for 8 days | Max winnings £100 | 20x wagering | 40x on deposit bonus | 30-day expiry | Note that the full T&Cs apply.

Bonus spins have a very reasonable 20x playthrough requirement. They are eligible for use on the following exciting Age of Gods titles: Epic Troy, Glorious Griffin, Ruler of the Seas, Ways of Thunder, and King of Asgard.
As with most of the best online UK casinos, game contributions vary towards your wagering requirements. See how Casino.com splits theirs below:
- 100% – Slots (excluding those that bonus funds are ineligible on) and scratch cards
- 25% – Casino hold’em and roulette
- 20% – Baccarat, blackjack (all varieties excluding Blackjack Switch), sic bo, and video poker

4. Mr Play – Best Welcome Package for UK Players

- Day 2 – 20 spins on Finn and the Swirly Spin
- Day 3 – 20 spins on Book of Dead
- Day 4 – 20 spins on VIP Black

5. Casumo – Top Casino Bonus in the UK for Beginners
18+ | New UK customers only | Opt-in required | 20 bonus spins on “Sahara Riches Cash Collect” | Min Deposit £10 | 30x wagering req | 30-day expiry | Note that the full T&Cs apply.
- 100% match up to £25
- 20 bonus spins
- 30x wagering requirement for both spins and deposit bonuses
Casumo Casino’s casino sign-up bonus reflects their whole site’s attitude: Simple & Sweet. Opt-in is required while making your minimum £10 1st deposit to take advantage of this nice little package.
Casumo will match 100% of your first deposit up to £25 and credit your account with 20 bonus spins on the top-notch “Sahara Riches Cash Collect” slot title – a great 5-reel game with medium volatility and 30 paylines.
Bonus spins and deposit bonuses are both subject to a 30x wagering req., with a max bet restriction set at £5 per spin. If you’re using those funds on table games and live casino games, you’ll be able to bet up to £10 per round, though different games will contribute different amounts to the wagering requirement (outlined below).
Players will be permitted to withdraw real cash funds, but any withdrawal made before wagering requirements are met will result in forfeiting all bonus funds.
Here is how much each game contributes to the wagering requirements:
- 100% – Slots: (unless stated otherwise)
- 50% – All wheel-game variants
- 10% – Video poker, roulette, baccarat, blackjack
- 100% – All other games
6. MrQ – Best No-Wager Casino Bonus in the United Kingdom
New customers only | 1st deposit with £10 min | No playthrough requirement | 30 bonus spins with code “BEAST” | 48hr Expiry | Note that the full T&Cs apply.
- 30 bonus spins with promo code “BEAST”
- No wagering requirement on bonus spin winnings
- Eligible on first deposit of £10 or more
The only thing better than free bonus spins on your favourite video slots titles is having the wagering requirements waived — and that’s precisely the case at MrQ.
Use the promo code “BEAST” during your first deposit of £10 or more and then spend at least £10 in MrQ’s casino section. Within minutes of meeting these two tiny requirements, you will have 30 bonus spins credited to your account for the Beat the Beast: Kraken’s Lair slot.
The best part is that with no wagering requirement on your bonus spin winnings, every pence you earn, you keep.

Bonus spins must be used within 48 hours, and any spin not used within that time will be lost. The fixed stake on each spin is 10p.
Wagers on the following games will not unlock your 30 extra spins: Aviator, Golden Hook, Incredible Balloon Machine, Roulette, Blackjack, Baccarat, or any other table game.
7. PokerStars – Best No-Deposit Offer in the UK
New customers only | No deposit req’d | No playthrough requirement | 50 spins granted on verification with 50 more after 24hrs | Winnings credited as cash after all bonus spins have been used | 7-day expiry | Note that the full T&Cs apply.
- No Deposit
- 100 Bonus Spins worth 10p per spin
- No Wagering Requirement
PokerStars proves once again that they are more than just a website to play cards. Their “Welcome Aboard” no deposit package comes with a fantastic lot of 100 bonus spins subject only to account verification. No minimum deposit is required.
Not only that, but all wins will be rewarded as cash with no withdrawal restrictions or wagering requirements. This makes it one of the top casino bonuses for UK customers.
Players will see their bonus spins awarded over 2 days with 50 bonus spins upon account verification, and 50 bonus spins 24hrs later. All bonus spins must be used within 7 days of being awarded, and while there are several games they’re valid on, there are too many to list here.
Once all bonus spins have been used up, winnings will be awarded as cold, hard cash.
8. Casushi – Best Casino Bonus in the UK for Book of Dead
New players only | £10 minimum deposit | 50 spins usable on “Book of Dead” only | 40x playthrough requirement | Bonus spins expire after 2 days | £250 max winnings | Note that the full T&Cs apply.
- 100% match up to £50
- 50 spins on a fan-favourite slot machine
- 40x playthrough requirement
Book of Dead is one of the most popular video slots titles at the moment, so we’re absolutely pumped to be able to share with you Casushi Casino’s solid welcome bonus that comes with a fistful of free plays on this title.
To qualify, brand new UK players must make their 1st deposit of £10 or more (we recommend depositing the full £50 to get the maximum bonus). Once done, Casushi will start releasing your Book of Dead spins over 3 days: 30 spins on deposit, 10 after 24 hours and another 10 spins 24 hours after that.
All spins are valued at 10p per spin and are credited as bonus funds, and the game’s bonus win cap is set at £250. Any bonus wins over that will be manually adjusted down.
The deposit bonus funds will expire after 30 days, while the Book of Dead spins will expire 2 days after being credited. While the bonus and winnings are separate from cash funds, withdrawing cash while there is still an active bonus will cause you to forfeit the remainder of your bonus amount.
9. FansBet – Highest Match Bonus for New UK Players
New players only | 200% match on deposits up to £100 with code “CASINO-200” | Cash deposit must be played through 40x to unlock bonus funds | No wagering requirement on unlocked bonus | Note that the full T&Cs apply.
- 200% deposit bonus up to £200 with bonus code “CASINO-200”
- 5 bonus slot spins
- Deposit needs to be wagered 40x to unlock the bonus
FansBet has come up with a fairly interesting way of handling deposit bonus funds. Using the online casino bonus code “CASINO-200” on your first deposit of up to £100 will get you 200% in bonus money… but you don’t have access to it right away.
To make those bonus funds count, you have to wager 40x your initial deposit on FansBet’s slot machines before they release the deposit bonus to you. But once you’ve made that bonus valid, you get the full bonus amount as cash with no further playthrough requirements.
The biggest hitch in what the FansBet Casino bonus offers is that the above-mentioned 40x cash wagering contribution must be completed in 7 days to validate this first deposit bonus. If not, the bonus expires, and you lose out on the full bonus amount.
You are able to make as many deposits as you’d like during this 7-day time period, though. So if you’ve had a run of bad luck and are really gunning for that 40x deposit playthrough, you still stand a chance at unlocking that online casino bonus.
If you’re excited about snagging a 200% deposit match and think you can play through the 40x requirement before the bonus expires, click here and use the bonus code “CASINO-200.”
10. RocketPot – Best UK Crypto Casino Bonus
New players only | 100% crypto bonus up to 1BTC | 100x playthrough requirements | Game restrictions apply | Note that the full T&Cs apply.
- 100% match on qualifying deposits up to 1BTC
- 100x rollover (playthrough requirement)
- 10% cashback on losses
Related: Best Litecoin Casinos
RocketPot is perfect for crypto enthusiasts who want to maximise their play. With 100% match on cryptocurrency deposits up to 1 Bitcoin, you’ll have plenty to keep you playing for quite some time.
Our biggest grievance is their steep 100x playthrough requirement, which will indeed be a grind to meet. As with pretty much every other casino on our list, if you make a withdrawal before your playthrough requirements are met, the bonus funds in your account will be forfeited.
There are also several games that either do not count towards the rollover or only fractionally, so it would be worthwhile to carefully read through all of the terms and conditions before playing anything.
You don’t want to spend an afternoon playing the Triple Tigers slot only to find out that none of your bets were going towards the playthrough requirement.
If you’re a crypto fiend looking for a solid deposit bonus, click here to claim your 100% match of up to 1 BTC from RocketPot.

How We Determine the Best UK Casino Bonuses
Bonuses are like homemade cookies in that we like to go for the bigger ones first before they’re gone. We really try to keep an eye out for high-percentage match bonuses with high deposit caps as we feel it’s one of the best ways to keep playing with the casino’s money.
While a large playthrough requirement will not entirely disqualify a casino bonus from our list, the UK casino will have to sweeten the pot with many other features before we’d consider it worth our time – and ultimately yours. Anything over 35-40x starts to feel like more of a hassle than it is worth unless the bonus size is massive and you’re willing to go big.
Bonus’ Terms and Conditions:
Nobody reads the Terms and Conditions these days… Well, nobody but us, it seems. While putting together this list, we’ve gone through every casino bonus’ T&C to try and suss out any curve ball and stipulation UK online casinos might throw at you. Then, to ensure all is fair, we factored that into their grading.
While this is probably our lowest priority when ranking bonuses offered by online casinos in the UK, we’re not above a bit of bribery. A fist full of bonus spins or cash-back offerings can make a humdrum bonus beat the competition.
Everything You Need to Know About UK Online Casino Bonuses
Are No-Deposit Bonuses Actually Free?
They are, yes. Though depending on the casino, your no-deposit welcome bonuses are likely going to be subjected to some extra high wagering requirements. While that’s the case most of the time, you have casinos like 888 and PokerStars that offer no-deposit bonuses with zero wagering requirements.
What are Playthrough/Wagering Requirements?
Wagering requirements – or playthrough requirements – are the number of times you have to play through a given amount before your winnings are eligible for withdrawal. For example: If you have a UK casino bonus of £10 and the wagering requirement is 35x, you cannot withdraw any winnings from the casino bonus until you have bet £350 with it.
What Kind of Games Can I Use My UK Casino Bonuses On?
Some casinos put strict requirements on exactly what game types or titles their bonuses can be played on (e.g. “can only be used on video poker, roulette, or slots” or “bonus spins for Book of Dead”), while others have no such restrictions.
We’ve read through the Terms and Conditions and will note in our bonus reviews above if we’ve found that the bonuses are limited to certain games.

Can I Claim Welcome Bonuses More than Once in UK Online Casinos?
In almost all cases: No. There are a few online casinos, however, that make this answer more complicated.
- Some UK casinos offer a tiered welcome bonus, with bonuses broken up over the first x number of deposits.
- Other casinos offer welcome bonuses that can be claimed for separate parts of the casino site (i.e. poker welcome bonus, sportsbook welcome bonus, and casino welcome bonus).
But in general, you cannot claim the same bonus at the same casino more than once. Heck, most online casinos in the UK won’t even let two people in the same household claim the same welcome bonus, even if they have two completely different accounts.
Claim a Claim Bonuses at Multiple Online Casinos in the UK?
Yes. In fact, a lot of welcome bonuses are aimed at experienced players and are built specifically to draw a little bit of business away from competitors. You can follow the footsteps of many UK players and keep a list of your favourite welcome bonuses and hop from one casino to another as your bonus funds run out.
