100% Deposit Bonus UK

Online casino gaming and bonuses tend to go hand in hand nowadays. You’ve likely seen a plethora of banners advertising all sorts of different offers and incentives for signing up and playing at new UK casinos. What you have to figure out is which promotions are right for you and whether or not they’re as rewarding as they seem. 

That’s why we’ve dedicated this page to the standard 100% deposit bonus. So, read on to discover all of the information you’ll need to understand this particular offer so that you can make an informed decision as to whether or not you should opt-in.

What Is A 100% Welcome Bonus?

In essence, a welcome bonus is an online casino’s primary method of incentivising new players to create an account and make a deposit. It’s something that new players can claim to bolster their bankroll to experience a wider range of casino games whilst getting an overall feel for a new site.

However, it’s important to note that not all welcome bonuses are equal; it’s not a matter of one size fits all and various casinos provide different offers. So, let’s take a look at the 100% welcome casino bonus to see precisely what you can claim.

100% welcome bonuses grant an exact match on your first deposit up to a specified amount. That means after you sign up and opt-in (you may need to make use of a specific bonus code to activate the offer), you’ll be eligible to receive the additional funds. The casino will then credit your account with the stated amount in the form of bonus funds. 

So, what did this mean in purely financial terms? Well, if we were to use an example of a site advertising a 100% up to £100 welcome bonus this would mean you could claim an additional £100 in bonus funds. If you were to make a first deposit of £100, the casino would then match it with another £100, giving you a total of £200 to play with. Sounds good, right?

However, certain terms and conditions will apply and you’ll want to be aware of these beforehand. Specific terms such as wagering requirements, wagering caps and validity periods play a pivotal role in a welcome bonus’ overall worth. It’s important that you carefully consider these elements as it’s unlikely you’ll be able to withdraw any bonus funds until you’ve met each stipulation. You needn’t worry though, we go on to cover these in greater detail further down the page.

Do All Casinos Offer A 100% Deposit Bonus?

100% bonus featured

As you can surmise from the list above, there’s a fantastic range of casinos that provide a 100% welcome bonus. Yet, despite it being the most common introductory offer, it isn’t available at every site; some may advertise less, whilst you may be eligible for a better bonus elsewhere – if you’re looking to get even more out of your deposit, check out our 200% welcome bonus page.

One thing that remains consistent though, irrespective of the size of the bonus, is that you’ll need to make a real money deposit to be eligible. This differs from the less frequently available no deposit bonus which does not require you to add any funds to your account – the bonus is added as soon as you’ve signed up.

You’ll also need to ensure that you meet the minimum qualifying deposit if you want to receive the extra funds. This amount will be listed within the bonus T&Cs but, again, it can vary from one casino to the next so it’s always worth taking the time to check before committing to a payment.

Is A 100% Welcome Casino Bonus Just For New Players?

As a rule of thumb, only new players who do not already have a preexisting account are eligible to receive a 100% casino welcome bonus. It’s an offer that applies to your very first deposit, doubling the amount of money you have to play with.

That being said, it may also be part of a larger package, with multiple deposit offers and even reload bonuses included. Therefore, it’s worth shopping around to compare the different offers if you’re looking to get the most out of your payment.

Game Selection

As we’ve previously mentioned, when you receive your welcome it’ll likely come in the form of bonus funds. This is often credited into a separate wallet to help you distinguish the difference between your real money balance but there are occasions when both amounts may be combined.

Generally, you’ll be able to use these funds as you see fit, thus allowing you to experience a wide range of casino games – online slots, table games and many other iGaming genres. The main caveat, however, is that a maximum bonus bet may be in effect when using your bonus – this means any wager you place exceeding the limit will not count towards wagering and may even cause your bonus to become null and void.

How To Claim A 100% Welcome Bonus

Claiming this type of offer is a relatively straightforward exercise. However, for those of you who are newer players, we’ve provided a step-by-step guide below to help you get started.

Is The 100% Welcome Bonus Right For Me?

You should never make hasty decisions when spending money at online casinos. Likewise, it’s always advisable to weigh up the pros and cons of utilising bonuses to potentially extend your time playing. Sometimes, these offers may appear flashy and rewarding but you should always delve into the terms and conditions to gain a better understanding of what’s really on offer. To help you decide whether or not a 100% welcome is the right fit for you, check out our table of pros and cons below.

✅ 100% extra cash to play with❌ Requires a real money deposit
✅ Offer may include additional rewards – free spins, additional deposit bonuses or reload bonuses❌ You cannot request a withdrawal until you meet the attached wagering requirements, else you may forfeit your bonus
✅ You can play your favourite games for longer or try out different titles❌ Excessive wagering requirements may present an unrealistic chance of turning your bonus funds into real cash

Wagering Requirements And 100% Welcome Bonuses

generic bonus uk

Unfortunately, nearly every offer will have strings attached. The most prevalent of which is the bonus’ wagering requirements. This dictates how many times you’ll need to wager your total bonus before whatever remains is converted into real money, thus becoming eligible for withdrawal.

For example, a 100% up to £100 bonus that has a 35x wagering requirement means you’ll need to wager a total of £3,500 before you can request a cash withdrawal. Therefore, you’ll always want to aim for offers with minimal wagering. Always pore over the T&Cs to ensure you’re in with a realistic chance of turning your bonus into cash.

Gamble Responsibly

Given the ubiquitous nature of this type of offer, it isn’t difficult to get sucked into using one and then moving on to another at a competing casino. If you play within your limits and maintain tight budget control, it is something that you can utilise to great effect. However, we strongly advise you to always take responsible gambling precautions so that you don’t spend more than you can afford.


This page has everything that you could possibly need to know about 100% deposit bonuses, but if you are of a curious disposition then we have highlighted some additional questions that you may be itching to ask.

This is a casino offer that will 100% match the amount of your first deposit up to a specified amount. After creating a new account, you’ll be eligible to receive the additional cash in the form of bonus funds which you can use to play for longer.

You can use the extra cash you receive from a welcome bonus to play a diverse range of casino games. It’s often the case that you can try out all sorts of different online slots and table games. However, certain restrictions may apply so it’s worth checking the T&Cs beforehand – this mainly precludes you from playing live casino titles unless otherwise stated.

Traditionally, only new players making their very first deposit are eligible to receive a welcome bonus. That being said, certain offers come with multiple bonuses that allow you to earn additional funds on subsequent deposits.
