Best No Deposit Bonuses for UK - May 2025

No deposit bonuses are a great way to start at a new casino, with you receiving free spins without having to make a deposit on-site. Being able to try out a casino without staking any of your own money has to appeal to all players, doesn’t it? Here, we look at the best no deposit bonuses available in the UK to help you choose your next casino.

Offering roughly 1,000 video slots, Mad Slots offer a quality slots product from the best developers on the UK market. Keep an eye out for their innovative Live Hourly Hot RTP section, which updates you which of their slot games that are currently paying out the most.

I had to place Mad Slots at the top of my no deposit bonus list because their 100 free spins can be played on the excellent, Big Bass Splash. As one of the most popular games currently on the market, if you are able to trigger a Free Spins Bonus within the game, you could be turning that bonus into a very nice cash payout. I also liked the relatively low wagering of 30x here as it gives you a genuine chance of turning your bonus funds into real, withdrawable cash. It is important to note that not all 100 free spins are instantly credited to your account - these free spins are credited across five different 20-spin batches.

A household name since they first launched back in 1997, 888 Casino remains one of the most popular casino sites in the UK. Their games collection boasts more than 2,000 titles, which includes a wide variety of exclusive games, across both slots and live casino.

The 888 Casino no deposit bonus forms part of a double welcome offer, with new players also able to claim a 100% deposit match bonus (up to £100) the first time they deposit on-site. The max win limit of £100 on your no deposit free spins is eye-catching here, as are the relatively low 30x wagering requirements, and it would be higher up my list if they hadn’t restricted the free spins to eight of their own exclusive slot games. However good Sizzling Hot Jokers may be… I would still prefer to have my 88 free spins on Big Bass Splash!

Launched back in 2018, Luck Casino is an exciting addition to the UK casino market that offers a strong collection of 1,250+ slots from the best developers in the business. They also have a reputation for peppering their existing players with a steady stream of bonuses and promotions - so the generosity doesn’t stop with their eye-catching no deposit bonus.

Luck Casino is another top quality no deposit casino, with it only falling down my list because of the slightly higher wagering requirements, and the fact that the free spins are restricted to a less desirable slot game - Sky Piggies. The other important thing to note here is that the 100 free spins are split into five batches of 20 free spins, with each batch having a max win limit of £10.

Powered by Markor Technology, Hot Streak is a slots-focused site that offers 500+ video slots, as well as a handful of casino titles. Perhaps their most enticing feature is their mobile apps, with both of them receiving strong reviews in the App and Google Play Store.

When focusing purely on the number of free spins - 10 - it is hard for Hot Streak to compete with the other names on this list who offer dozens more free spins. Pair with that the very high wagering requirements at 60x, and the possibilities of turning your no deposit spins into real cash may seem unlikely. However, I feel I need to focus on the positives here, and that is the fact the free spins are available on the excellent NetEnt slot, Finn and the Swirly Spin, and the max win limit is a generous £200.

As the name suggests, a no deposit bonus is a casino bonus that does not require you to make a deposit on-site for you to receive it. Once you have registered with a new casino, your no deposit bonus will be credited to your account.

What are the Different Types and Components of a No Deposit Bonus?

When it comes to a no deposit bonus, there are a number of different variations available, including:

• Free spins - an amount of free spins to be played on specific slot games
• Cash bonus - a cash bonus amount that can be used on casino or slot games
• No deposit bonus codes - you will often be required to enter a specific code to receive your bonus. Failure to do this will result in your bonus not being added to your account.
• You might also receive a bonus that consists of a combination of the two, allowing you to experience both casino and slot games before making your first deposit on-site.

Things to Look For in a No Deposit Casino Bonus

With casinos effectively giving you something for nothing with this sort of bonus, they will come with a fair amount of conditions attached, including: 

• New players only - as an introductory offer to a new casino, this sort of bonus is only available to new players
• Wagering requirements - a set amount of times you must turnover the cash value of your bonus before it is eligible to be withdrawn
• Max win limit - a limit will be set on the maximum amount you can win from your free spins or bonus cash
• Time limit - all welcome bonuses will have some sort of time limit attached to them. With free spins, this can be an amount of hours, while deposit match bonuses tend to be up to 30 days. Whatever it may be, I would recommend checking this when you sign-up to a new online casino.
• Limited game selection - when using this sort of bonus, your gameplay will be restricted to specific games

How Does a No Deposit Bonus Work?

While these bonuses may seem very simple at face value, they often come with a number of terms and conditions attached, which are important to consider before you claim them. Without these stringest terms and conditions, a player could simply sign-up to a new casino, spin their free spins, withdraw their winnings and never return to the casino again. With that in mind, let us better explain how wagering requirements work when it comes to a no deposit bonus.

If you receive a bonus that has a cash value of £10 (100 free spins at £0.10 each), you must wager at least £300 before you are able to withdraw any winnings. 

I would also recommend checking the game contributions as not all games on-site will contribute 100% towards these wagering requirements - slots will usually contribute 100%, while casino games can contribute as little as 10%, which means you would need to wager a minimum of £3,000 to clear the same wagering requirements.

Why Do Casinos Offer No Deposit Bonuses?

No deposit bonuses are a great way to get a player started at a new casino before they risk their own money. So, just why are casinos willing to give new players something for nothing with these sorts of bonuses - let us explain:

• Attract players - offering potential customers a ‘try before you buy’ option is going to be a crowd-pleaser in any industry
• Retain players - if a player has a positive experience with this sort of bonus, the casino has a very good chance of retaining them
• Brand awareness - particularly important for lesser-known casinos, this sort of bonus allows them to build trust with new players who may not have previously been aware of their brand
• Promoting new games - casinos will offer this sort of bonus as an opportunity to test the popularity of a new game
• Upselling - it is not uncommon for casinos to pair a no deposit bonus with another welcome bonus - whether that be a free spins offer or a cash-match offer. Once the no deposit bonus has built trust, it is more likely that a new player will be willing to commit their real money to a site in order to claim a further welcome bonus.

How to Choose The Best No Deposit Bonuses

As I have already stressed, this sort of casino bonus comes with a fair amount of terms and conditions attached - because the casino is effectively giving you something for nothing. When it comes to choosing one of these bonuses, it is crucial to consider all the different components of it, to give you the best opportunity to convert those bonus funds into real, withdrawable cash.

Your first focus should be the wagering requirements - with the industry standard tending to hover around 30x. Much like with a game of golf, the lower the number, the better for us here! If a casino is offering 100 free spins with 75x wagering requirements, it is going to be a real uphill struggle to turn their bonus funds into real cash.

Another important element to consider is the max win limit, which outlines the maximum amount you can win from this sort of bonus. There’s nothing worse than hitting it lucky on a slot and winning £100, only to find the max win limit is £50 - so I would always recommend checking this number BEFORE you start playing with your bonus.

How to Sign Up for a No Deposit Bonus

Claiming a no deposit bonus should be very straightforward, with new players simply asked to sign-up to a new casino to have the bonus credited to their account. 

Let’s take a closer look at the Mad Slots registration process to see just how easy it is to claim a no deposit bonus.

• Step 1 - Complete their simple two-step registration process by providing your email address, mobile number and proposed password
• Step 2 - You will then receive an authentication code to your email address
• Step 3 - Your Mad Slots account will then be credited with your first batch of 20 free spins
• Step 4 - The next 80 of your total 100 free spins entitlement will be added to your account in four more 20-spin batches
• Step 5 - You can keep track of how far you have played through your wagering requirements in the bonus section of the site, or by contacting customer support
• Step 6 - Once the wagering requirements have been met, you will be eligible to withdraw your winnings to your chosen payment method. You might need to provide some more personal information before making this withdrawal.

How We Rank The Best No Deposit Bonus Casinos

There are a number of elements we consider when ranking our favourite no deposit bonuses - these include:

• Amount of Free Spins - your eye - and our’s - will obviously be drawn to the casinos who offer the most free spins with these sorts of offers. If a casino is offering 100 free spins, it gives you a real chance to try out a site before you start playing with your own money.
• Size of Cash Bonuses - similar to the free spins no deposit offers, we will always prioritise casinos that offer the highest cash offers. 
• Wagering Requirements - perhaps the most important element to consider when ranking any no deposit casino - any casino that offers 30x or less gives you a real fighting chance of converting your bonus funds into real, withdrawable cash.
• Max Win Limits - this sort of bonus comes with varying maximum win limits attached to them. It is crucial that you check what this is before you start playing with your bonus funds.
• Game Selection - this is a really important factor for me because your casino experience is hardly going to be a good one if your bonus spins are restricted to a rubbish game, are they? Offering free spins on a top quality slot game is a real plus for me, and a great way to get you started at a new online casino.

Tips for Using No Deposit Offers

When it comes to claiming a casino bonus, your principal aim will be maximising your potential winnings. Beyond avoiding casinos with too restrictive conditions - high wagering requirements and low max wins - I would also recommend focusing on games that offer you the best chances of winning - if you are able to choose the game you play your bonus funds on.

Games with lower volatility and higher RTP (of 96%+) offer you a very good chance of turning your bonus funds into real cash as you play through your wagering requirements.
