Our Best No Deposit Bonus Offers

We've tested a bunch of UK sites with no deposit bonus offers, and these few really stood out this month. They all give you something for free up front, no deposit required, and they keep rewards coming once you start playing for real money.

21 Casino 

• Licence: UK Gambling Commission (licence number 52894)
• No deposit bonus – 21 free spins on Book of Dead
• Deposit bonus – 100% match bonus up to £500

21 Casino is one of those sites that never sits still – they're always adding new games, which is partly why we rate them so highly. You'll find titles from big names like NetEnt, Big Time Gaming, and Evolution, so there's no shortage of quality slots, tables and live casino titles. 

The site itself looks sharp and runs smoothly. Verification is quick, and withdrawals are usually processed within 24 hours. Plus, you've got all the main payment options covered – Visa, Paysafecard, PayPal, Neteller, the lot. 

There's no app, but you won't miss it – the mobile site loads quickly and works well on all Android and iOS devices. 

You'll get 21 free spins on Book of Dead just for signing up – no code, no deposit. It's a nice way to have a nose around and see what the site's about. 

If you like it, it's worth chucking in a tenner later on. 21 Casino doubles your first deposit up to £500, so you'll have plenty to play with once you've used up those free spins.

PlayGrand Casino

• Licence: UK Gambling Commission (licence number 52894)
• No deposit bonus: 30 free spins on Book of Dead
• Deposit bonus: 100% match up to £100 + 30 free spins on Reactoonz

A sister site to 21 Casino, Playgrand is just as stylish with its slick black-and-white theme. We've been fans of its games lobby since the day we reviewed it – and honestly, it's only got better with time.

These guys know how to pick a line-up. They've got strong ties with over 100 game providers, so the selection is fantastic – slots, roulette. jackpots, you name it.

Withdrawals are processed within 24 hours, the payout rate sits at around 96.3%, and support is on hand 24/7, which is what you want if you play late. 

New players get 30 no deposit free spins on Book of Dead just for signing up – no promo code needed. You can claim it on your phone too; the site works nicely in your browser, so there's no need to download any apps.  

And if you fancy sticking around after that, your first deposit opens the door to more spins and rewards. You'll get a 100% match up to £100 plus 30 free spins on Reactoonz – it's fast, chaotic, and seriously good fun.

Knight Slots Casino

• Licence: UK Gambling Commission (licence number 39326)
• No deposit bonus: 50 no deposit free spins on Big Bass Splash – no bonus code needed
• Deposit bonus: 100% match up to £50 + 50 free spins on Book of Dead

PlayOJO might be all about wager-free bonuses, but Knight Slots – run by the same team – is giving new UK players 50 free spins, no deposit needed. There's no bonus code either. 

Launched in 2020, Knight Slots is a properly modern casino with a stunning games library and a six-level VIP club – a bit of a rarity in the UK these days.

The numbers aren't bad either – over 1.5 million in jackpots paid out each month, 24-hour cashouts when you win, and more than 2,000 games to pick from. You'll find slots, blackjack, roulette and live casino tables from top names like Play'n GO, Evolution, Yggdrasil, BTG, and NetEnt.

When you sign up, you'll get 50 free spins on Big Bass Splash from Pragmatic Play. And if you want to keep playing on, your first deposit unlocks more spins and plenty of ongoing promotions.

There's no one-size-fits-all no deposit bonus promos. Different casino sites have different approaches, especially new casinos. But the idea is the same – they want to give you more chances to play than what you've put in your account initially.

Once you’ve opted in and met the requirements, you can use the no deposit bonus funds to play casino games. No need to spend your own money.

One of the most popular no deposit promos is the free cash bonus, where online casinos in the UK give you real money to play with just for signing up. This type of offer is perfect for testing games and casino sites without using your own funds right at the start.

A free cash bonus no deposit casino UK deal (that’s a real money bonus with no deposit required) is tough to find, but not impossible. Some of the newest online casinos may offer such perks as a way to attract new players. These no deposit casino bonuses are usually smaller than the bonus cash you get when making a deposit. But they’re still great, often giving you £5 to £10 or sometimes more in free cash to enjoy on games.

Keep in mind, though, that no deposit offers may come with slightly higher terms than usual. For example, you may need to wager the bonus 40x or more before you can withdraw, and winnings might be capped at £50.

Players can’t get enough of free spins, and iGaming sites know it. These offers give you the chance to play and win big without parting with your own cash. Think of them as the golden tickets of the casino world. 

The best payout online casinos sometimes offer these as a standalone promo when you sign up. But often they’re tacked onto other bonuses like bonus cash and deposit match offers. They’re a great way to get more than you bargained for when you sign up for a new casino with a no deposit bonus. 

Again, and not to spoil the party, but there may be wagering requirements attached. This means you'll have to play and bet your winnings from bonus spins a few times before you can cash out any money. Also, there are limits on which slots you can use the spins on and the maximum bet you can place on each free spin.

You can get different amounts of free spins. Some sites offer a 25 free spins no deposit bonus, while others might give you 100. But usually, you'll get 5, 10, 20, or sometimes 50 free spins.

If you're on the lookout for more no deposit bonuses at UK online casinos, some of the best offers come from new online casinos. Looking to stand out in a crowded UK market, these sites often provide generous no deposit bonuses to attract first-time players. Just be sure to check for a valid UKGC licence and study the wagering requirements before signing up.

A cashback no deposit bonus does what it says on the tin. Once you sign up and add funds - including any gifted bonus funds you might have – you’ll be ready to play. With a cashback offer, you’ll get offered some of your money back whenever you play certain games and lose.

This usually applies to slots. But we’ve also seen cashback promos extended to table games and live casino titles.

The cashback bonus amount is usually in the region of 5% to 10%. It might not sound like a lot at a glance, but that’ll add up. What’s more, some of the sites that run this do so as a lifetime offer. This means you'll get funds back from every lost wager without needing to deposit again for life.

Signing up is one thing, but the best online casinos know they need to keep you around. While the no deposit bonus UK promos we list aim at new players, that doesn’t mean the fun ends there. 

Weekly or daily spin offers are especially common. You may also find bonus funds dropped into your account as occasional sweeteners. They can sometimes be as big as £10 or £20. You can then play and wager on games with this money rather than dipping into your own pot. 

LeoVegas casino is one site we know is class for dishing out to existing players. While their welcome offer requires a £10 deposit, their competition for free spins doesn't. By liking LeoVegas posts on social media, you can win some sweet perks with no deposit or wagering required.

A no deposit bonus is a free play bonus you receive from an online casino, most often when you join as a new player. Yes, that's right, you don't need to deposit to claim it. It's one of the best ways to try out a casino without spending money, and is often packaged as a free welcome bonus no deposit deal.

Here's how it works: 

• First, sign up with a UK-licensed casino site. You can use our list for inspiration. 
• At most UK casinos, you'll need to verify your identity. Don't worry if you're asked for personal details – KYC checks are standard in the UK.
• Read the bonus terms and conditions. Check the wagering requirements, bonus expiration date, and games.
• Now you're ready to claim your bonus. This could be free spins (available exclusively for slots) or bonus cash (usable on a mix of casino games). 
• Play your bonus on eligible games. Most no deposit bonuses are tied to specific games selected by the casino.
• If you win, fulfil the wagering requirements and head to the cashier to cash out your winnings.

The process of claiming no deposit bonuses can vary slightly between UK no deposit casino sites. Here are a few examples.

Automated No Deposit Bonuses. Many casinos make life easy and add your bonus automatically. Once you've completed your sign-up and verified your account (if requested), you’ll find the bonus in your casino's profile, ready to use.

Opt-In No Deposit Bonuses.  Some UK no deposit casino sites will prompt you to opt in during registration to claim a no deposit bonus. You may need to choose from multiple welcome offers, so be sure to select the one that you want before completing sign-up.

No Deposit Bonus Codes. Some sites ask for no deposit casino bonus codes. If your bonus isn't showing in your promotions basket, look on the casino's promotions page or the bonus ad for any active casino promo codes. Then enter the code in the dedicated field to collect your no deposit bonus.

If you’ve met the no deposit bonus conditions, here’s how to cash out winnings at a UK no deposit casino:

1. Visit the cashier – Found in your casino profile.
2. Choose a withdrawal method – Some no deposit bonus casinos require using the same method as your deposit.
3. Enter the amount – Stay within the casino's withdrawal limits.
4. Confirm your request – Follow any additional on-screen instructions.
5. Check your account – Your funds will arrive within the specified time frame.

So you’ve joined an online casino with no deposit offer, met the requirements, and your bonus is ready to go. Now what? How do you get the most value out of it? How you use your online casino no deposit bonus in the UK depends on the operator's rules. It might only apply to certain games and could limit how much you can wager at a time.

Still, these tips will help stretch your bonus credit further and avoid common pitfalls along the way.

UK Casino No Deposit Bonus: The Dos

To give yourself the best chance at turning bonus funds into real-cash winnings, focus on strategies that work. Here's what to do when your bonus is active:

You’ll usually have a few options where you can use bonus funds and spins. Not all games will be eligible, so if you pick the wrong one, you'll end up dipping into your own money. Slots are almost always covered by bonus rewards, though there's usually a select list of titles.

Table games such as blackjack or roulette are rarely included in an online casino no deposit welcome bonus. And when it comes to live casino titles, coverage varies a lot by operator. Some UK no deposit casinos extend these promos to live dealer games, while others restrict them entirely. Always check the bonus terms before choosing a game in the lobby.

Slot games with a higher return to player (RTP) percentage will, on average, pay out more often than low RTP slots. When you have a limited number of free spins or credits, it’s vital to get as many wins as possible in a short time.

All online casinos will impose a cashout limit on no deposit bonuses. You don’t want to go through the emotional rollercoaster of winning a big jackpot only to find your no deposit bonus comes with a £20 cap on cashouts. Always check the T&Cs of a no deposit bonus to see how much you can withdraw, then play accordingly.

Wagering the minimum stake might make your bonus credit go further. But completing the wagering requirements will take much longer. You should opt for an average or higher bet if given the option. You’ll either lose fast and move on or max out your win and claim a bigger prize.

Sticking with one or two paylines might feel like a good way to stretch out those bonus credits. Each play will cost less after all. But you’ll be seriously lowering your chance of uncovering a winning payline or hitting a jackpot by limiting your options in this way.

It’s easy to get carried away with a UK casino no deposit bonus, especially when the offer looks too good to ignore. But if you want to make the most of it, here’s what not to do.

Don’t Play On Unlicensed Sites

At Casinos.com, we always recommend sticking to a licensed online casino with no deposit bonus offers advertised on their websites. Playing at an unlicensed site puts your security at risk. There's no guarantee the games are fair, and your personal data and funds may not be properly protected.

Don’t Fall for Huge Bonus Offers Without Checking the Terms

If it sounds too good to be true, it could well be. Study the terms and conditions carefully, especially for an online casino no deposit bonus. Pay close attention to wagering requirements. These can sometimes make unlocking bonus funds more difficult than they appear.

Don’t Ignore High Wagering Requirements 

Anything over 50x is steep. Ask yourself if the free welcome bonus with no deposit required is actually worth your time. Sometimes it's might be better to walk away. That said, steep wagering requirements can give you more playtime, which can help explore the site or try new games.

No deposit bonuses are a great way to play for free, but there’s always fine print. Even the best no deposit bonus casino sites have cashout rules you’ll need to follow before withdrawing your winnings.

Here are the key terms you need to check before claiming your no deposit bonus:

• Cashout Limits. This is the maximum amount of funds you can withdraw from any bonus winnings. 
• Bet Limits. There may be limits around how much you can wager each time you spin or play while using your bonus funds. This will cap your potential winnings. 
• Payment Restrictions. No deposit bonus casinos have their own rules for claiming promos. For example, Visa casinos might only take debit cards or bank transfers. Meanwhile, Neteller casinos might only take e-wallets or cryptocurrency. Some casino payment methods might only work for deposits and not withdrawals. So, it's important to check these rules before you start.

Wagering rules can make or break your bonus – and yes, they also apply to no deposit bonuses. If you don't meet the casino's wagering terms in time, you could lose any winnings linked to your bonus.

To meet these requirements, you'll need to wager the total amount of your bonus funds a certain number of times. For example, say you receive a £10 bonus with 30x wagering. That means you'll have to wager £300 (£10 x 30) before you can cash anything out. Miss the limit stated in the rules, and your bonus, along with any potential winnings – disappears.

Want to avoid disappointment?

Use our wagering calculator to see exactly how much you need to bet. Tap the image, enter your bonus details and it'll do the maths for you. Simple as that.

You may be wondering how no deposit bonuses differ from other types of welcome packages. For example, it’s common to see no deposit free spins included as part of a broader welcome promo. 

But, most other bonuses need you to make a cash deposit first. Then you'll get a reward based on your deposit amount. For example, deposit £20 and get a 100% deposit match up to £200 – i.e., £20 extra in bonus funds. Then, like with most no deposit bonuses, you'll have to wager your £20 bonus cash a certain number of times. At most casinos, it ranges between 30 to 40 times.

With a regular deposit bonus, how much you’re willing to deposit is front and centre. You can use one to boost your bankroll big-time, but the bigger the funds, the more you’ll have to play through in total.
