Free Spins No Deposit Bonus UK (July 2025)

A no deposit casino bonus lets players try out a casino site without funding their account first. As the name suggests, these bonuses do not require an initial deposit.

No deposit free spins are the most common type of offer, granting players a set number of spins on specific slot games chosen by the casino. However, no deposit bonuses can also come in the form of bonus funds or free cash, which may be used on a wider selection of games, depending on the promotion's terms.

It is important to note that these bonuses come with terms and conditions - most notably, wagering requirements. These tend to be higher for no deposit bonuses and must be met before you can withdraw any winnings from your account.

At Gambling.com, we feature the latest casino no deposit bonuses, including those with the lowest wagering requirements:

A free spins no deposit UK bonus offers a set number of free spins when you sign up to a new no deposit bonus casino. These bonus spins are typically limited to a specific slot game.

New online casinos will occasionally offer players cash incentives for registering. Typically, it will be a small free bonus amount - such as £5 or £10.

This type of no deposit bonus is now increasingly rare, with it being typically reserved for high-rollers with an existing account. These bonuses come with short timeframes and steeper wagering requirements.

This is a bonus that is offered when you refer a friend to the casino, often with no deposit required on your part.

This is a special no deposit bonus that is given to loyal players or VIP members, rewarding continued play and engagement.

In some cases, you might need to enter a bonus code during registration in order to claim a free casino bonus. For example, click below to access your exclusive no deposit bonus code from NetBet:

Free spins offered with no deposit required are a promotional tool used by casinos to attract new players. They provide a risk-free way for players to play top slot games without any upfront financial commitment, making them an appealing introduction to a new casino.

To minimise their own financial risk, casinos will often assign a relatively low value to these free spins - typically 10p or 20p each. This helps keep the cost of this sort of promotion more manageable.

Moreover, the no deposit bonus will come with wagering requirements. These requirements mean that any winnings from the bonus must be wagered a certain number of times before they can be withdrawn as real cash, making it more challenging to turn bonus funds into real, withdrawable money.

• Win real money: Enjoy the opportunity to win real money without the need to deposit any of your own funds
• Risk-free play: Experience casino or slot games in a completely risk-free environment, removing any financial pressure while you play.
• Try popular slots: Ideal for exploring top new slot tiles such as Book of Dead and Starburst, to give you a taste of these games before committing any of your own money.

• High wagering requirements: No deposit bonuses typically come with steep wagering conditions, often as high as 50x or more, making it challenging to turn bonus winnings into withdrawable cash.
• Restricted gameplay: These bonuses are usually limited to specific casino games or slots, restricting your chance to explore a new casino site.
• Low win limits: Winnings from no deposit bonuses are often capped, which means there will be a relatively low limit to the amount of money you can cash out.

Claiming a no deposit bonus is a simple process that should only take a few minutes.

1. Choose a trusted casino from our exclusive list of no deposit casinos.
2. Sign up for an account by filling in your personal details.
3. Verify your email or phone number in order to activate your account. 
4. You might sometimes need to enter a specific bonus code to receive this type of no deposit bonus.
5. Once your account is registered and verified, the bonus should be automatically added to your balance. If not, I would recommend visiting the promotions section or contacting customer support to claim it.
6. Before using your bonus funds, it is crucial to carefully review the terms and conditions, including wagering requirements, game restrictions and withdrawal limits.
7. You can then use your bonus funds to play the eligible slot games.
8. If you win using your bonus funds, you must meet the wagering requirements within the time frame before being able to withdraw your winnings.
9. Once all of these requirements are met, you can withdraw your winnings up to the maximum win limit stated in the terms and conditions.

• Ignoring wagering requirements: Failing to understand the wagering conditions can result in frustration when trying to withdraw winnings. Be sure to check how many times the bonus amount must be wagered before you start playing.
• Missing the expiry date: These bonuses can often come with short time limits. If you don’t use your bonus within the specified period, you risk losing it altogether.
• Playing low-RTP games: If you have the option to choose which games to play, we recommend avoiding low RTP (Return to Player) games. Opting for higher RTP games improves your chances of getting a return on your free spins.
• Not verifying your account: Many casinos require you to verify your account before your bonus is credited or you can process a withdrawal. Failing to complete verification may result in delays or even the cancellation of your winnings.
• Overlooking withdrawal limits: With these bonuses often coming with a win cap attached, exceeding this can lead to you forfeiting the extra winnings.

No deposit bonuses are often centred around popular casino games, with slots being the most frequently featured. Iconic titles like Book of Dead, Gonzo’s Quest and Starburst are commonly included in these offers due to their broad appeal. These slots also offer high RTP percentages, increasing your chances of turning bonus credits into real cash.

In some cases, no deposit bonuses may include free cash that can be used on table games like blackjack or roulette, though this is less common than slot-specific offers.
