Best First Deposit Bonus Casino Sites in the UK

First up, we have a novel system of ranking and evaluation used internally by our seasoned experts. We examine the bonus structure, read the terms and conditions, check the community reports, and look at everything that can lend insight into the fairness and clarity of a platform’s promotional habits. Licensing, security, and the overall user experience are also factored into this formula.

Next, we conduct a detailed analysis of the wagering requirements of the first deposit bonus (generally 30x to 60x). The wagering requirement is the number of times you have to play through the received bonus amount (in some cases, the combined total of the received bonus amount and the deposited amount) before any winnings resulting from the bonus can be converted into withdrawable cash. We make sure that we are only recommending the first deposit bonuses that carry a fair and achievable wagering requirement by firsthand testing the bonus ourselves.

We look at the winning odds associated with each first deposit bonus. This includes evaluating which games contribute to fulfilling the wagering requirements and how often players are likely to win based on the odds. A well-balanced bonus will always offer a reasonable chance of winning—we know that by experience. It is only a matter of finding the right casino sites that have this priority for their players.

Many first deposit bonuses include free spins, and we evaluate the number of spins, the value per spin, and the eligible games. A lot of shady online casino platforms are notorious for slapping a free spins offer on the first deposit only to pair it with a subpar slot game. If the game’s RTP is low and the terms dictate a low max win cap on your spins, it is as good as burning your money in the fireplace directly. None of these bonuses make it into our recommendations.

Wagering Requirements

Always check the wagering requirements attached to the first deposit bonus before claiming it. This specifies how many times you need to wager the bonus before you can withdraw any resulting winnings. A lower wagering requirement (such as 30x) means it is easier to unlock your bonus and enjoy your winnings.

If you are getting a 100% deal at 60x wagering, then a deposit of £100 will be matched with a bonus of £100. This additional £100 in bonus will need to be played through 60 times. In other words, you will need to wager a total of £6,000 on the casino to withdraw any winnings from the £100 bonus.

Note that some deals apply the wagering requirement on the combined total of the received bonus and the deposit amount. In this case, the total becomes £200 x 60 = £12,000.

Maximum Bet

While the first deposit bonus is in play (actually, this is true for any type of welcome bonus or package), you are limited on how much you can bet per spin. As slot games pay based on a multiplier (such as 15x your bet if you match 5-of-a-kind), you just might get lucky. Casinos hedge themselves against this by capping how much your per-spin coin value can be. In UKGC casinos, you are already limited to £2/£5 per spin, but the limit can be lower for the bonus as well. Any spins with a coin value higher than this can void your bonus.

Maximum Cashout

The maximum cashout is a simple limit—it is the maximum amount of money you can receive as the bonus. If you have a 100% matched deposit bonus with an upper cap of £200, you cannot get more than £200 in total bonus funds no matter how much you deposit. If you truly wish to maximise this, you will deposit £200 to get another £200.

Bonus Expiration

Bonuses expire too! Typically, free spin first deposit bonuses will expire in 5-15 days and matched deposit bonus amounts can expire in up to 30 days. Before you activate/claim a bonus, be mindful of the expiry time to avoid any nasty surprises. The bonus free spins or amount will simply disappear if you are too late in using them.

Casino Safety Index

The casino’s safety index is a combination of multiple variables—operator’s reputation, website security, payment processors, licence, etc. It is not always easy to determine a casino’s safety index on your own. Gambling Zone has detailed reviews of all online casinos catering to UK slot enthusiasts and punters, so read our reviews to compare various casinos and how reputed and secure they are before signing up.

Select the Right Casino

The first step is to find the right casino. We have put together a list of recommended online casinos that you can join. These offer friendly terms and carry a good reputation in the UK market. Look at their first deposit bonuses and decide for yourself which online casino works for you.

Create Your Account

Once you have decided on the casino site, you need to create an account. Usually, signing up on a new casino site is a straightforward process. Some casinos might request more information than others, including your phone number and address. Email confirmation can also be required. If the casino has a promo code field, make sure you know whether or not to fill it at this point to claim the bonus.

Verify Your Identity

It is always recommended to do the KYC steps by submitting your documents as quickly as possible. After signing up, go to your profile and do the necessary validations. The casino will ask for some documents and you will need to wait some time before your account is verified. It is best to wait this period out before making your deposit because if for any reason you are not verified, it can be quite time-consuming to get your deposit back.

Make a Deposit

Once you are verified, it is time to make your first deposit to get the bonus. Read the bonus terms once again and pay attention to the minimum deposit required to activate it. Typically, the minimum deposit is £10 or £20, but it can also be higher or lower depending on the casino in question or what the exact promotion is.

Now, there are three possibilities:

1. Automatic Credit: In most cases, once you make a qualifying deposit, the bonus amount or free spins will get credited to your account immediately and automatically. There is no other step.
2. Enter a Promo Code: In some cases, you might need to enter a promo code while you make your first deposit to get the bonus. If you fail to do so, your account will forfeit the first deposit bonus permanently.
3. Manually Activate the Bonus: Some casinos require you to manually activate the first deposit bonus from your profile. This is done to give you some time if you need it. Also, if a casino has multiple promotions that you can choose from, the options will be shown in your profile section for you to activate the one you prefer.

Enjoy and Use Your Bonus

And that is it! Once you follow all the steps above, your bonus balance or credited free spins will show up in the bonus section of your profile or wallet. You can start using this bonus right away. Do keep in mind that in the case of bonus funds, the cash balance (your deposit amount) will be used first. Only after it is entirely exhausted alongside any winnings will you be able to use the bonus funds.
