No Deposit Casino Bonuses For UK Players (May, 2025)

UK No Deposit Bonuses Online casinos which are licensed and regulated in the United Kingdom, have an array of welcome bonuses on offer, including the popular no deposit bonus. In our opinion, there's nothing better than signing up to a casino and being able to claim a free bonus, so it's important to recognise the different free casino bonuses and understanding how they work, before opting in to anything.

Free Spins, Cashback, Free Play Credits

Promotional offers even casino bonuses are all used as a way of attracting new clientele, but which one is the best?

Only you can make this decision, as we like a bit of both. Whether you enjoy playing casino games on a desktop computer or your mobile device, you will be able to take advantage of these casino offers.

What are No Deposit Bonuses?

For UK residents, it can come in the way of a free casino bonus, which will allow you to play on any game featured within the casino. Basically, when you register, you will receive a ‘free cash' bonus in your bankroll, to use as you see fit. This type of offer usually has time restrictions attached to it; typically, 30 days (but this will vary), which means you have that set amount of time to use your bonus cash before it is confiscated.

Casino Spins

Next up is the most popular no deposit bonus; the free spins (Called 'Casino Spins' in the UK due to the UKGC guidelines). Everyone loves to spin slots for free, which is why this bonus is the most claimed. Free spins will be credited to your account once registered and again, they will have rules attached to them.

Some gambling sites award slot play instantly...

...others may dish them out over consecutive days after the point of registration. If this is the case, you will have a short period of time to play them through, or they will be removed from your bankroll.

Cashback

Receive this type of free play, but only after you make a deposit, so be wary of that one. Cashback works very much like using a card when shopping; you can accept cashback on your purchases, only with online casinos, you receive cashback on your losses – usually over a set period of time. With this offer, players will receive the funds back as a casino bonus, which means it won't be credited to your bankroll and will also have wagering requirements.

How to Claim

To claim your bonus, you will need to register; don't be alarmed if the operator requires a casino payment method before awarding the bonus.

Why do I need to add my card details, if it's free?

Don't be alarmed by this – it's common practice which allows the casino you are registering with, the ability to verify your identity and to confirm you are the legal age for gambling. No cash will be taken from your account – unless you authorise a deposit.

The registration process is simple...

...requiring the basics only. Your name, address, email, gender, telephone number and most importantly; your date of birth. If the no deposit welcome offer displays a bonus code, you will need to insert this into the registration form – if there was no code listed, then you won't need one, even if the registration form features a referral (or bonus) code section. Once registered, the bonus will either be sitting in your bankroll or you will have free spins waiting to be played on the stated slot machines.

Can I Keep What I Win?

How to Claim All casino bonuses come with terms and conditions (free spins too), which you should read before accepting any offer. Wagering requirements should play a big factor in the decision to accept a bonus or not, as this means the winnings accrued from that bonus, will probably be subjected to a certain turn over requirement.

We say ‘probably' because the majority of online casinos will require you to play through the bonus before being able to withdraw – but you do have a small group of online casinos, who actually allow you to keep 100% of what you win.

Here is a typical example of wagering:

A no deposit casino bonus of £10 with a 40x wagering requirement, will need to be played through to the value of £400 before cashing out. The higher the bonus you receive, the more you will need to play through.
