Types of UK No Deposit Bonuses

Before you claim one of our great No Deposit Bonuses, you better know the types you can get.

Generally, there are two different types of No Deposit Bonus:

No Deposit Credits

No Deposit Credits

No Deposit Credits are the most common type of No Deposit Bonus. When you claim a No Deposit Bonus you’ll receive Bonus Money to wager as you please. Perfect for testing out a casino’s content, No Deposit Credits come with fewer games restrictions than No Deposit Free Spins.

Energy Casino

Example: Claim your credits here!

When you sign up with Energy Casino they’ll give you £5 in No Deposit Bonus Credits to try out their games. This means that, once you register with the casino, you’ll receive £5 in your Bonus Account. You’ll have to wager this bonus 50x before you can withdraw your winnings.

No Deposit Free Spins

No Deposit Free Spins

Are you receiving offers for ‘Bonus Spins’ or ‘Extra Spins’? Not to worry. This is only because you are playing from within the UK.

‘Bonus Spins’ and ‘Extra Spins’ are the exact same product as ‘Free Spins’. The only difference is that they may come in conjunction with an offer that requires a deposit. As the UK Gambling Commission insist, to call these ‘Free Spins’ would be misleading.

Are you a fan of slot games? If the answer is yes, then you’ll love No Deposit Free Spins Bonuses. When you claim this offer and sign up, the casino will give you a number of Free Spins. Usually, these Free Spins are limited to a single slot game, or a set of games – for example:

Karamba Casino

Example: Take Karamba Casino for a spin!

When you sign up with Karamba Casino they’ll give you 20 Welcome Spins on the slot game Starburst. You don’t have to deposit and they’ll be credited to your account instantly. This bonus comes with a Wagering Requirement of 35x before you can withdraw.

UK No Deposit Bonus Rules 2021

Do you want to claim a bonus without having to wade through pages of small print? Here at No Deposit World we want to make it as easy as possible to go from finding a bonus, to playing.

So long as you’re aware of the following rules, you’ll know what to expect from your No Deposit Bonus:

Wagering Requirements: How can you win using a No Deposit Bonus? Well, first you have to play through the bonus’ wagering requirements. This means that you have to wager your bonus a number of times before you can withdraw.

Unless stated otherwise (and casinos will state it because it makes the bonus more desirable), most bonuses come with wagering requirements. To fulfil a bonus’ wagering requirements is very simple.

Let’s use an example:

Energy Casino

Example: Can you beat the wagering requirements?

Energy Casino are currently offering new players a £5 No Deposit Bonus when they sign up. This bonus comes with a wagering requirement of 50x.

If you multiply the value of the bonus with the wagering requirement, you get the sum total you have to wager:

value of bonus (£5) x wagering requirement (50) = sum total playthrough (£250)

This means that you have to wager £300 before you can withdraw any winnings made from the bonus.

Winnings Cap: The stars have aligned: you’ve played through the bonus’ wagering requirements, and you’ve won! But, for some reason, you’ve only received a portion of your winnings. This will be because the bonus you’ve taken up comes with a winnings cap.

Casinos place a cap on winnings to ensure that their losses are not too detrimental. An online casino is a business, after all, they can’t be giving away all of their profits! Winnings caps allow players to win real money using No Deposit Bonuses, and at the same time help to moderate the casino’s losses.

Time Limits: Sometimes, when you claim a No Deposit Bonus, you’re not only playing against the casino, but against the clock. You have to spin, spin, spin those reels before the time runs out, or else your winnings may be invalidated. Always remember to use up your bonus before your time limit ticks over.

Game Eligibility: This is important. When you claim a No Deposit Bonus it may only be valid on a select number of games. If you stray from the eligible games, your bonus may be invalidated by the casino.

Luckily for us, most online casinos will advertise the eligible games within their promotion. If there’s a specific game you want to play, make sure you select a bonus that permits it.

No Deposit Casinos on Mobile

No Deposit Mobile Casinos

A wise man once asked: “If a casino doesn’t work on mobile, does it exist at all?” The answer is: if it does, it won’t for much longer. The times are changing, and if a casino isn’t optimised for mobile they’ll fall behind the competition.

The intense competition in the online casino industry makes it a necessity that casinos keep up with the times. All of the casinos on our list work seamlessly on mobile. This means that you can claim a No Deposit Bonus regardless of your platform.

How to Claim a UK No Deposit Bonus

If it’s your first time claiming a No Deposit Bonus then don’t worry, we’re here to help.

All you have to do is follow these simple steps:

Online casinos want you to register and use their bonuses. For this reason they will always do their best to guide you and make the process as effortless as possible.

Are UK No Deposit Bonuses Entirely Free?

A No Deposit Bonus is offered by casinos so that new players can try out their content. Online casinos hope that the player enjoys spending their bonus and eventually chooses to deposit. But the fact remains: if you don’t deposit, you don’t pay.

Our advice is simple. Take advantage of multiple No Deposit Bonus offers. This way you’ll be able to test out a variety of casinos until you find the one that suits you best.

Do I need a Bonus Code?

Nowadays, fewer online casinos require you to use a Bonus Code to claim their No Deposit Bonuses. If you are required to use a Bonus Code, the steps to claiming the Bonus are very easy.

Here’s what you have to do:

There’s no reason to be put off by this extra step – online casinos want you to sign up. They’ll make the process as straightforward as possible. They’ll either ask for the Code when you sign up, or require you to enter it into their cashier section.


Which is the best online casino in UK?

The best online casino is the casino that best fits your preferences. If you want to try your hand at slots, pick a casino with a large variety of slots. If you want to play on mobile, choose a casino that are Mobile gaming specialists.

Whether you like to spin the reels, roll the dice or play a hand, we’ve got an online casino bonus for you. There is no limit on the amount of casinos you can try out. Just scroll through our list, take up a No Deposit Bonus, and give one a go.

Which casino game has the best odds?

Unsurprisingly, Blackjack is the casino game with the best odds. As well as being easy to learn and play, Blackjack also comes with a house-edge of just 1%.

Slots are a different matter altogether. Occasionally, you can find slots with an RTP (Return to Player) of 97% and over, but this is rare. Online casinos sometimes let you check the RTP% of their slots before you play them.

What are No Deposit Bonuses?

No Deposit Bonuses are a kind of promotion offered by online casinos to attract new players. Upon registering, the online casino will credit your account with bonus funds. This allows you to make bets without having to deposit any of your own money.

Can you win real money from no deposit free spins and no deposit credits?

The simple answer is: yes. The complicated answer is: yes, but it’s more difficult than you might imagine.

Free Spins and No Deposit Credits come with certain restrictions, which may include:

  • Wagering Requirements
  • Winnings Caps
  • Time Limits
  • Game Eligibility

Can you win real money on free slots?

You can win real money on free slots so long as they’re free in the sense that you’re using a No Deposit Bonus. To win real money using this method you have to fulfil the wagering requirements of your bonus. Only then will your winnings be redeemed as real money.

You can’t win real money on Free Play slots. Unless you’re wagering Bonus Credits, Free Spins or your own money, you won’t be able to win real money.

What does a no wagering bonus mean?

If a bonus comes without wagering requirements it means you’re in for a treat. Wagering Requirements are a kind of restriction online casinos place on bonuses to moderate their losses. If a bonus comes without wagering requirements, it means you can turn that bonus into real money a lot easier.

Where can I find the best No Deposit Bonuses in the UK?

Today’s your lucky day because you’ve already found them. Our list of the best No Deposit UK Bonuses lets you choose from the most generous bonuses around. Scroll through our list, select the one you like, and see if your day can get even luckier.

What is the safest online casino?

For an online casino to operate legally in the UK they have to obtain a license from the United Kingdom Gambling Commission. Why is this important? Because the UK Gambling Commission is one of the strictest and most respected gambling authorities in the world.

A UK Gambling license is therefore difficult to get. This may limit the variety of casinos you can choose from, but it does certify that they are fair, reputable and trustworthy.

How have the new UK Gambling Advertising restrictions affected No Deposit Bonuses?

The UK Gambling advertising restrictions, introduced in 2017, effect No Deposit Bonuses in two ways. Firstly, online casinos have to be clearer in their terms and conditions. This has led to Free Spins being more accurately described as ‘Bonus Spins’ or ‘Extra Spins’.

Secondly, casinos are required to pay 15% in tax on any promotion used to entice new online casino players. Inevitably, this has led to casinos promoting less, and players having fewer No Deposit Bonuses to choose from. But you’ll be glad to know that it has had no effect on the overall gaming experience.
