UK No Deposit Bonus FAQ

A no deposit bonus code is a unique sequence of numbers and letters that allows you to redeem a no deposit bonus. For example, Paddy Power Casino is currently giving away 100 free spins to all new players who use the bonus code “PGCTV1”. To redeem this bonus, you simply have to sign up and then go to the casino’s cashier. You will then copy and paste the bonus code from our site into the designated field.

For more information on how to use a bonus code, check out our section on How Bonus Codes Work.

To win real money, you must first wager your no deposit bonus or free spin win.

Essentially, this means you must play an amount equivalent to between 30 and 70 times the bonus credits you have received, or the amount you have won with free spins. You must also be aware of other bonus terms, such as expiry dates, win limits and game restrictions.

No deposit bonuses are ideal for any new player that wants to try out a new casino, explore new games and play at the best UK online casinos for free. Another additional benefit is that no deposit bonuses allow you to win real money without putting your own funds at risk (providing you fulfil the terms and conditions of your bonus).

With more than ten years in the online casino industry, we know precisely how to identify an excellent casino site. Furthermore, our standing in the industry enables us to negotiate exclusive deals that you cannot find elsewhere.

There are two types of no deposit bonuses – free spins and bonus credits. The main distinction between the two is that free spins are generally valid on select games and have a fixed coin value. When you receive bonus credits, you can play a variety of slots and adjust the bet size as you see fit. Occasionally, you can even use these bonuses on other types of casino games, such as Keno, scratch cards and live casino games.

Top 5 UK No Deposit Bonus Codes

Although bonus codes are gradually becoming a thing of the past, many casinos still use them.

Here is a list of excellent casinos using bonus codes:

How Bonus Codes Work

Bonus codes are a series of numbers and letters that casinos use to identify a specific bonus offer.

Therefore, casinos using bonus codes will always require you to enter a bonus code when you redeem their offers. Let us use one of our offers to demonstrate how this works:

If you look at our list of recommended casinos, you will see that NetBet offers new players 20 no deposit free spins on Starburst. Since NetBet does not have the status ‘No Code Required – automatic’ stated beneath its offer, you will need a bonus code to receive the bonus.

To retrieve the bonus code, you must click on the link that takes you to the NetBet review, in which you will find the bonus code stated at the top. If the code is already stated in the casino list, you can copy it directly from there instead.

Follow these steps to redeem a bonus that uses a bonus code:

  1. Step 1: Copy the bonus code from the casino list or review.
  2. Step 2: Click on the Claim Now in the review or top list.
  3. Step 3: Sign up with the casino and paste the bonus code when you are asked to. Most of the time, you will be prompted to enter the bonus code during the registration process, but occasionally you might have to enter it in the cashier after your registration is complete.

Types of UK No Deposit Bonus Codes

No deposit bonuses comprise two types of offers- free spins and bonus credits. Our top lists are jam-packed with both, and to better take advantage of these bonuses, you must understand what sets them apart.

No Deposit Bonus Credits

With this type of bonus, you’re typically offered a nominal bonus credit balance, typically between £5 and £10 that you can use to play a host of casino games like slots, roulette, or blackjack, depending on the UK online casino site. All you have to do to claim this bonus is visit any of the UK no deposit casinos listed on this page and click the Sign-Up, Register, or similar button. Fill out a new account registration form, opt-in for the bonus, and then verify your new account.

When you log in to the casino for the first time, your free funds should be in your account, or you may have to contact casino customer support to unlock and make them available for you. If required and supplied, enter the bonus code.

If you want to bank your winnings and convert them into cash you may need to make an initial deposit.

No Deposit Free Spins

With this type of bonus, you receive a number of free spins to use on one or more pre-selected online casino slot games. Depending on the casino, you may receive anything from 10 to 150 free spins. Click any casino on this page with a free spins offer, take a minute to register for a new real money account (don’t worry, this won’t require a deposit), opt to accept the bonus, verify your account, and log in with your username and password.

You should get a pop-up or some kind of message that your free spins are ready and waiting for you. Some casinos limit their free spins to one particular slot, albeit one of their most popular, while others may offer you a selection to choose from.

Once you have used your free spins, you will be able to transfer the maximum account to a bonus balance. At this point, you will need to wager this bonus money the prescribed number of times.

UK No Deposit Bonus Terms and Conditions

Before you roll up your sleeves and redeem one of our bonuses, you must familiarise yourself with the associated bonus terms.

Here are five aspects you must consider when you play with a no deposit bonus:

  • Wagering Requirements – You must play through the value of your bonus a number of times before you can withdraw your winnings.
  • Expiry Dates – You must use and wager the bonus within a specific time frame.
  • Win Limits – Winnings are capped at a specified amount, usually ranging from £20 to £100.
  • Bet size limits – Specify the maximum amount you are allowed to play per spin when you use bonus credits.
  • Eligible Games – You can only use your bonus on eligible games. This means that you must avoid playing excluded games when you are using bonus credits or wagering your bonus winnings. You will find excluded games listed in the casino’s user terms.

Wagering Requirements Explained

Wagering requirements are one of the most important, and perhaps also the most complex, bonus terms to grasp.

To wager a bonus, you must stake an amount equivalent to 30 to 70 times the value of your bonus, or the amount you have won with free spins. The lower the wagering requirement is, the better.

Example

Let us use an example to put this into context. Assume you receive a £10 bonus with a wagering requirement of 20x. This means you must stake £200 to convert the bonus to real cash.

£10 bonus x a 20x wagering requirement = £200 to wager.

As soon as you have played £200, any remaining bonus funds will immediately be transferred to your cash balance. When you play with free spins, the wagering requirement is applied to the amount you have won.

What happens if I do not follow the terms and conditions?

If you do not comply with the bonus terms, you may have your winnings and bonus confiscated. When you have wagered a bonus and request a withdrawal, the casino will examine your gaming history carefully to ensure you have played per its terms and conditions. Therefore, you should never play ineligible games or place bets that exceed the set bet size limit.

UK No Deposit Mobile Casino Bonuses

It wasn’t all that long ago when the first desktop online casinos started to emerge, shaking up the long-established global land casino industry. Today mobile casinos are fast replacing those same desktop pioneers. While desktop online casinos (for PCs and laptops) are still very much active, most now come standard with mobile counterparts that are accessible on smartphones and tablets for the ultimate in remote gaming convenience.

One country leading the way in terms of no deposit mobile casinos and sheer number of licensed and regulated sites is the UK. With so many mobile phones and devices in use in the nation, it’s not surprising that mobile casinos are so popular and becoming more so every day. You’ll struggle to find a premier UK online casino that doesn’t have a cutting edge no deposit mobile site that can be enjoyed anytime, anywhere on any device.

Most top UK no deposit mobile casinos can be accessed on any ‘smart’ i.e. internet-enabled phone or tablet regardless of its make, model or operating system (OS). In other words, whether you have a Samsung Galaxy running Android, a Nokia phone running Windows, the latest Blackberry or an iPhone X running Apple iOS, you can register a new account, claim a no deposit bonus, play games, deposit and cash-out all using your mobile device.

Although most mobile casinos have smaller game choices than their desktop counterparts, they always have a cross-section of their most popular games. Plus they are available 24/7 and can be accessed anywhere with fast and stable internet access via LTE, 4G, 3G or Wi-Fi. To keep things fresh and exciting, our casino review team is always on the lookout for new UK mobile casino sites with generous and exciting no deposit bonus offers.
