Best Casino Bonus in the UK

Latest Casino Bonuses in the UK

Let’s take a look at some of the best online casino offers for new players in the UK:

Top 3 Casino Offers in the UK in April 2025 by Our Experts

We’ve selected our top 3 casino offers based on their values, accessibility and wagering requirements.

888 Casino – £200 Bonus (200% Match Offer)

We ranked 888 Casino’s welcome offer as the best out there for UK players due to its impressive maximum amount of £200. By depositing £100, you’ll get those £200 as a bonus, giving you a solid payroll to start your betting journey.

The 30x wagering requirements, to be met on slot games, as well as the £10 minimum deposit, are pretty average conditions, making this offer even more attractive. To benefit from this promotion, you have to claim it within 48 hours after making your first deposit. After that, you have 90 days to meet the wagering requirements, otherwise the bonus expires. This time limit is quite generous, so we encourage you to claim the offer right after you register and make your first deposit!

Casumo Casino – Get £100 Extra & 50 Spins

Casumo is one of the best platforms in the UK, and it shows in its welcome offer. It offers both extra funds and free spins, and not just in small amounts. The £100 bonus would be a top offer by itself, so when combined with 50 free spins, valued at £0.10 each, on Big Bass Bonanza, it gets the second place on our ranking.

Similarly to 888 Casino, the 30x wagering requirements (with 100% participation from slots) on this offer are quite reasonable, however, this time you’ll need to deposit a minimum of £20. To activate this promotion, you need to click on the Valuable before making your first deposit. Your funds and free spins will automatically be credited to your account. You’ll have 30 days to meet the wagering requirements before expiration, right around the industry’s average. This makes Casumo’s welcome bonus an all around great offer to get you started!

Duelz Casino – Up to £100 Bonus & 100 Free Spins

Duelz Casino delivers a solid welcome offer that combines both bonus funds and free spins, making it a great option for new players. With a 100% match bonus up to £100, your initial deposit is directly doubled, giving you extra funds to explore the casino. On top of that, you’ll receive 100 free spins on Book of Dead, a fan-favourite slot known for its high volatility and nice 5000x max win.

While the 30x wagering on the bonus funds is in line with industry standards, the 45x requirement on free spins winnings is slightly higher. The games participating in meeting those requirements are mostly slots, at 100%, and some table games at 40%.This promotion has a £500 total win cap, and free spins expire after only 3 days, which is a big downside (funds, on the other side, expire after 30 days). Still, if you’re looking for a well-balanced offer with a mix of cash and spins, Duelz Casino is definitely worth a try!

How We Rank the Best Casino Bonus Sites

We base our rankings for casino offers on many criteria, the most important being the following:

• Bonus size: This is our first criterion, being what appeals the most to players. A high-value casino bonus will usually be better than a low-value one. We say “usually”, as we’re going to see other factors come into play!
• Wagering requirements: If a generous welcome bonus comes with unreasonable wagering requirements, the real value of the offer drops significantly! In the UK, the average requirement is 35x, so this should be a good indicator of a bonus’ real value.
• Game eligibility: Do the bonus funds or free spins need to be used on a specific game, or a small selection of games? We like to prioritise casinos on which you’re free to use your bonus as you please.
• Reputation & trustworthiness: The top casinos from our lists are all licensed by top regulators like the UK Gambling Commission (UKGC), ensuring all players will be safe using their platform. We also make sure they offer fair bonus terms for all players, and show transparency on responsible gaming and data protection.

Comparison of the Best Casino Bonuses in the UK

If you’re looking for something specific for your casino offer, check out our specific rankings for each criterion.

Casino Bonuses by Highest Total Value

This ranking is all about the absolute value of each bonus, not taking into account any wagering requirements. If you want to get the most out of your registration or first deposit, here’s where you should take your business:

888 Casino stays on top with its generous 200% bonus up to £200, while 32Red £150 bonus puts it in second. Some casino bonuses don’t offer an immense value, but they definitely have other advantages, which we’ll see in other categories.

Lowest Wagering Casino Bonuses

Low wagering requirements offer more freedom to players, by allowing them to withdraw their winnings more easily. Let’s see which bonuses are the best options on this matter:

PlayOJO, Bally Casino and NetBet stand out on this ranking with their no wagering bonuses. It means that you’ll be able to withdraw any winnings you get from their offers, without having to play through them again! The average wagering requirements in the UK is 35x, giving you an idea on how each offer compares to the industry standard.

The Best Free Spins Value in the UK

Let’s find out where you can get the most value out of a free spins offer:

Slots Animal offer the highest potential value for their free spins, although it’s not guaranteed that you’ll get all 500 spins when registering there. If you want to be sure of what you’re going to get, NetBet offers 100 free spins when you deposit and bet £10 on slots, without any wagering requirements! If what you’re looking for is the highest value per spin, Bally is where you should go, with £0.20 per spin, compared to the industry average of £0.10.

Best No Deposit Casino Offers

To skip the first deposit part and still get a welcome bonus, here’s where you’ll want to take a look:

888 Casino and Sky Vegas offer a solid amount of no deposit free spins, allowing you to start spinning by registering and entering a valid card on their platform. No deposit required, your spins will be credited to your account and you’ll be able to get some action going for free! If you’re more of a cash bonus person, William Hill is the way to go, as it gets you £20 without depositing anything.

Cashback Bonuses in the UK

If you’re looking to extend your gameplay by getting some of your deposits back, a few casinos offer cashback bonuses:

The best offers in this category are without a doubt the ones from All British Casino and Duelz. For every lost deposit at these casinos, you’ll get 10% back directly on your account (whenever you want on All British, once a week on Duelz). For example, let’s say you lose £20 on slots. With these casinos, you’ll get £2 back! Finding cashback offers higher than 10% is pretty rare, which makes those bonuses so valuable.

Terms and Conditions of Casino Offers

Before choosing a sign-up bonus, or any other promotion, you should always check its terms and conditions, to avoid any surprise that could prevent you from getting the most out of it. The main terms you should be checking are the following:

Be sure to take a look at all those elements before making a decision on your casino bonus offer!
