What Types of 100% Deposit Bonus Can You Claim in the UK?

The term ‘100%’ in 100% deposit bonus offers depicts the money you get from your deposit after claiming the bonus. Also, your rewards may not often come as bonus cash. Find out about the major types of 100 deposit bonuses below, including how often they appear in UK casinos.

100% Matched Deposit Bonuses

Matched deposit bonuses are the most dominant among all other forms of 100% deposit bonuses.

It is an offer that gives you bonus cash matched according to your deposit up to a specific limit outlined by the casino.

Suppose you make a casino deposit of £50 in your newly opened casino account. In that case, a 100% matched deposit bonus would give you an extra £50 in your bonus balance, which you can use to play your favourite games.

Matched deposit bonuses often come with wagering requirements and bonus expiry dates, so you must beat these requirements before requesting a withdrawal.

100% Deposit Spins Bonus

100% Deposit Bonus Spins

If you are a fan of slot games, then you must be familiar with bonus spins. These are bonuses that give you chances to play slot games for real money.

Generally, these spins can come as part of an existing 100% deposit bonus or as a standalone offer. As a separate offer, 100% deposit bonuses often come in the form of 100% deposit free spins.

This means that you receive a cash equivalent of a specific number of free spins upon making a deposit.

After receiving the incentive, you can use them on eligible slots to start playing toward your wagering requirements. These bonuses appear like any other 100 deposit bonus.

However, the bonus cash you receive is only usable on slots. And unlike primary 100% matched deposit offers, these bonus spins often feature lower value offers ranging from £5 to £30.

100% Deposit Free Bet

In most UK casinos, you will also find 100 deposit bonuses dedicated to sports betting. These offers often come as 100 deposit free bets. The 100% deposit bonuses that come as free bets operate like standard deposit bonuses.

Instead of receiving bonus cash in your account, you are granted free bets that can be used to wager on specific games or sports events.

How to Claim a 100% Deposit Bonus

Claiming the 100 deposit bonus is a breeze. To assist you, we’ve listed a step-by-step guide on how to claim the bonus in UK casinos:

  • Choose your preferred online casino. You can select any from our recommended sites as they are all licenced, reliable and secure.
  • Go to the casino’s login/sign-up page and click the ‘Create an account’ or ‘Sign-up’ button.
  • Fill in your details in the required fields. Most casinos only require basic information like your name, address, email, phone number, date of birth, etc.
  • Complete the registration and verify your account via email or SMS verification.
  • Login to your new casino account and open the payments tab.
  • Select ‘Deposit’ and proceed to choose your preferred deposit method.
  • Input an amount you wish to fund into your account and proceed to confirm payment. Ensure to confirm the minimum deposit that’s eligible for the reward.
  • Start playing your favourite games when you receive your deposit bonus.

If your deposit bonus features a bonus code, you must correctly insert this code in the required field. In some casinos, you will have to input this code during sign-up.

However, in others, the process takes place during the deposit. Whichever the case may be, always use the right code so you don’t miss out on the lucrative offer.

Advantages & Disadvantages of 100% Deposit Bonus

Below, we’ve outlined the main pros and cons we’ve identified during our research, so you can fully understand what to expect when claiming 100% deposit bonus offers.

  • Thumbs-Up Icon Increased deposit value
  • Thumbs-Up Icon Higher winning chances
  • Thumbs-Up Icon Availability
  • Thumbs-Down Icon Maximum bonus winning limits
  • Thumbs-Down Icon Game restrictions

Let’s explore the benefits of using 100 deposit bonus offers. For starters, a 100% deposit bonus doubles the value of your initial deposit.

In other words, if you make a £20 deposit using the bonus offer, you earn an additional £20, making your total deposit worth £40.

And the higher your overall deposit value, the higher your chances of winning. In fact, 100% deposit bonuses increase your winning chances by up to 100. They also allow you to play a few rounds of some games without using your real money deposits.

Almost every online casino offers a 100% deposit bonus to UK players, making it widely accessible across various platforms. This ensures that players can enjoy the incentive regardless of their chosen casino.

This widespread availability presents a distinct advantage, enabling players to play from their preferred site and still benefit from the enticing bonus offer.

When deciding whether to sign up with a particular casino, it’s good to be aware of the downsides of using a 100 deposit bonus.

Most 100 deposit bonuses feature maximum winning limits, which stop you from withdrawing above a specific amount. For example, a bonus rule may state that with the 100% deposit bonus, you can win a maximum of £200.

This means that even if you’re extremely lucky and your winnings total £500, you still won’t be able to withdraw anything over £200.

And the other drawback to using 100 deposit bonuses is that there are often some game exclusions, like with most casino offers. As a result, your bonus funds will only work on selected games. Some games may also have little contribution towards your wagering requirement.

Popular 100% Casino Bonus Terms & Conditions in the UK

Like all bonuses, every 100% deposit bonus UK is subject to specific terms and conditions. In this section, we’ll outline some of the common bonus terms and conditions and explain how they function.

Wagering Requirements

A wagering or playthrough requirement represents the number of times you have to wager your total bonus amount before becoming eligible to withdraw your winnings.

It is one of the most crucial bonus rules in online casinos and is also present in every 100% deposit bonus unless otherwise stated by the host casino.

On average, 100 deposit casino bonus offers feature wagering requirements of 30-65x.

If you earn a £50 bonus from a 100 deposit bonus with 25x wagering requirements, you must wager £50 up to 25 times before requesting a cashout.

Time Limit

Casino bonuses often have time limits after which they expire. The specific duration varies and depends solely on the casino. While some 100% deposit offers may remain valid for only 24 hours, some can last for up to 3 days, while others can remain valid for up to 14+ days after activation.

To avoid disqualification, you must meet the wagering requirements before your 100 deposit bonus expires.

Game Selection

Most casino deposit bonuses come with certain restrictions regarding the games you can play. These permitted games often depend on the nature of the bonus you use. For example, you can only use free spins on slot games.

On the other hand, 100% matched deposit bonuses often allow players to explore other popular titles like blackjack, poker, roulette, etc. However, they have different game contributions towards wagering.

Payment Restrictions

Some casinos do not allow certain payment options to be used for claiming 100 deposit bonus offers.

Using an unsupported payment method would disqualify you from receiving the reward. Traditional payment methods like bank wire and debit cards often work with bonuses.

However, methods like e-wallets and cryptocurrencies aren’t always eligible in online casinos.

Minimum Deposit

Most welcome bonus offers in the UK require players to make a minimum qualifying deposit to activate them. These min deposit amounts are often set at £10 in UK casinos.

Sometimes you’ll find even lower required deposits in the minimum deposit casinos. However, there are some special bonuses where a casino may ask UK punters to make higher deposits.

Maximum Bonus Conversion

The maximum bonus conversion rate represents the highest amount you can make from a bonus. Understanding this bonus rule can save you a lot of complications, as you will better understand when to stop playing and when your bonus balance is due for a withdrawal.

When requesting payouts, all bonus funds exceeding the maximum limit become void, leaving you with only the max amount allowed. In most British casinos, this maximum bonus conversion rate is set at £50.

Best Alternatives to 100% Deposit Bonus Offers

Besides 100 deposit bonuses, several other bonus offers are available to players in UK casinos. Let’s explore these bonuses more.

No Deposit Bonus

No deposit bonuses are incentives that do not require any deposit to activate them. This bonus is the opposite of 100% deposit bonus offers. The only similarity both bonuses share is that they are usually designed for new customers in online casinos.

In most cases, you receive a no deposit bonus just for signing up and verifying your account at an online casino.

It’s similar with the free spins you get for registering a card: players only need to sign up and add their debit card details, and the bonus will be automatically credited to their account.

Unlike 100% matched deposit bonuses, no deposit bonuses often come with lower bonus amounts. Still, the ability to play casino games for real money without investing any of your own funds makes it a good offer.

Reload Bonuses

In most cases, reload bonuses also come as 100% matched deposit offers. However, unlike regular 100 deposit bonus offers designed for new players, reload bonuses are for existing players.

You can only claim this bonus when making a recurring deposit after your initial deposit.

Reload bonuses can sometimes be lower than standard 100% deposit bonuses. However, they give you some flexibility, allowing you to choose your preferred rewards, ranging from cashback to bonus spins, free chips, etc.

Top 100 Deposit Bonus Casino Games

There are several games available for your pleasure at UK gambling sites. Below are some of the top games you will find at 100 deposit bonus casino sites.


Slots are the most dominant games in online casinos. As a result, you’ll find them at almost every betting site. Many reputable game studios put in extra work to develop these top-notch slots, resulting in a continuous improvement in the overall quality.

As a result, the playtime and popularity of these slots among gamblers steadily increase over time. Besides the generally captivating themes, slots also feature huge payouts, allowing you to use bonus features and different winning combos for huge multipliers.

Some top slots in online casinos are Starburst, Gonzo’s Quest, Book of Dead, Sweet Bonanza, etc.

Video Poker

Video poker is a casino game that perfectly combines traditional poker and slot machines. The system offers five cards you can hold or discard before moving to a new draw.

Though this game features several additional elements to poker, it still follows the original poker hand ranking rules. You need enough knowledge about poker, as the game combines luck and your skills as a player.

This game is prevalent in 100 deposit bonus casinos. However, it often features lower wagering contributions.


Blackjack is a table game that also doubles as a perfect title for gamblers trying to understand card games in online casinos. In this game, your aim is to beat the dealer to a hand of three cards with the total value closest to 21.

This game is one of the popular table games in the UK online gambling scene. As such, it is available in many 100 match deposit bonus casinos online.

Examples of blackjack games include Blackjack Switch, Infinite Blackjack, Blitz Blackjack, etc.

Other Casinos Games in 100 Match Deposit Bonus Casinos

Apart from the games discussed above, here are some other top games you can find in casinos offering 100% deposit bonuses:

  • Bingo
  • Jackpots
  • Baccarat
  • Roulette
  • Keno
  • Scratchcards

How We Rank 100 Deposit Bonuses in the UK

How We Rank 100% Deposit Bonuses in the UK

Selecting the right 100% deposit bonus casino involves research and experience. Thus, it is quite a daunting task for many.

However, we’ve outlined some important factors we consider when ranking these bonuses in casinos. This way, you can better understand how to develop your research strategies.

Bonus Wagering Requirements

When ranking the best 100 deposit bonus offer, one of the first factors we consider is the wagering, also known as playthrough requirements.

A high wagering requirement can make it challenging to they significantly for players to withdraw their winnings from bonuses.

For this reason, we make sure to only rate bonuses with moderate wagering requirements from 20x to 65x.

Casino Licencing

Before choosing a 100 deposit bonus, we ensure they come from a reputable casino licenced in the UK. Casinos often display their licencing information publicly, so we inspect them to ensure they hold official licences from the UK Gambling Commission.

Besides the UKGC, we also rank platforms with licences from reputable gambling bodies like the Curacao eGaming Authority, Malta Gambling Commission, Alderney Gambling Control Commission, etc.

Playing at a licenced casino ensures safety, allowing you to enjoy a more enjoyable bonus experience.

Max Bonus Winning Limit

Like most bonus offers, 100 deposit bonuses often come with a set max cashout limits which players cannot exceed. A higher maximum winning limit allows players the opportunity to retain more of their winnings from bonus play.

A higher limit increases the potential for substantial wins without being capped at a low amount.

As a result, we often look for bonuses from casinos that support a higher max bonus conversion rate of at least £50.

Bonus Value

Depending on the casino, a 100 deposit bonus can come in different forms and values. We check out bonuses with higher reward values, allowing you to enjoy a better gameplay experience.

Besides the overall bonus value, we also consider factors like the general bonus support and how it pairs with the casino games at the platform.

Payment Support

In regions like the UK, payment support is an essential factor to consider when ranking bonuses. To ensure players experience no complications, we only rank 100% deposit bonus casinos that support all the UK’s major payment portals.

We rate brands that feature bonuses supporting deposits from e-wallets like Neteller, Skrill, and ecoPayz, and traditional payment options like debit card and bank transfers.

How to Make the Most of the 100% Deposit Bonus Offers in The UK

Maximising casino bonuses is tricky, as the outcome of almost all games depends on a player’s luck. The exception are skill-based games, but their contribution to the wagering requirements is often low.

However, we’ve listed 3 key tips we found to improve the gaming experience while using the 100% match deposit bonuses:

  1. Utilise your experience in familiar games
  2. Understand the bonus T&Cs
  3. Gamble wisely

Utilise Your Experience in Familiar Games

When most players receive bonuses, they use them as an avenue to explore unfamiliar titles. Of course, this is a good strategy, but not always. You must utilise your experience in familiar games to increase your winning potential with bonuses.

It is better to use free play modes when trying out unfamiliar titles to understand how these games work before opting in with your bonus money.

Understand the Bonus T&Cs

Before using any 100 casino deposit bonus, thoroughly review the bonus terms and conditions. It is a vital tip, as it can help you understand how to use an offer.

Some of the most crucial bonus rules you must understand are the wagering requirements, bonus expiry, max bet limits, and overall bonus conversion limits.

Sufficient knowledge about these bonus terms will allow you to maximise your winnings, and you’ll know the right time to request payouts.

Gamble Wisely

A good bonus-winning strategy in online casinos is to gamble wisely. Gambling is entirely luck-based, so it is almost impossible to predict each gaming session. As a result, the best way to save yourself, in the long run, is to gamble wisely.

Some casino games are overwhelming, so you can get lost in the moment. But always remember to stick to strict budgets during these moments.

If you find it hard to control your gaming sessions, consider using the responsible gambling tools available in the casino you use.

Final Thoughts

100% deposit bonus offers are known for many reasons, including simplicity, availability, and support. Unlike some promotions, these offers have gained immense popularity, granting you the flexibility to use the rewards across a range of exciting games.

So, if you’re looking to add an extra layer of fun to your gaming sessions, 100 match deposit bonuses are the way to go!

Whether you’re a seasoned player or new to online gaming, understanding how these bonuses work and how to maximise their benefits is key to unlocking a truly thrilling gaming experience.

Prioritise Responsible Gambling

Responsible gambling is a practice that encourages individuals to participate in betting and gaming activities in a way that is safe and mindful of their wellbeing and financial limits.

If online casinos and individuals prioritise responsible gambling, it fosters a safer and more enjoyable gaming environment for everyone involved.

Here at CasinoSherlock, we are big advocates of responsible gambling and always highlight its importance.

A responsible gambler adheres to the following:

  • Sets and sticks to a strict budget.
  • Doesn’t chase losses.
  • Keeps track of the time and money spent on gambling.
  • Refrains from gambling when feeling upset, angry, or depressed.
  • Don’t let gambling interfere with their daily responsibilities.
  • Takes breaks to avoid getting too caught up in the game.

🚫 Please note that in the UK, only individuals aged 18 and over are legally permitted to engage in gambling activities.

If gambling stops being fun, or if you or someone you know has a gambling problem, it’s important to seek help.

Reach out to organisations like GamCare or GambleAware that offer support and resources to promote healthy gambling habits, or call the National Gambling Helpline on 0808 8020 133.

Frequently Asked Questions

Below are some of the most popular questions about 100% deposit bonus offers in UK casinos.

Which is the best casino for a 100 deposit bonus UK?

Several factors come into play when selecting the best casino for 100 deposit bonuses. But some of the top sites where you will find this bonus in the UK are: Dream Vegas Casino, Mr Vegas, and 21LuckyBet Casino.

Do all 100% deposit bonuses come with free spins?

No. Free spins don’t often come as a part of 100 deposit bonuses. However, there are still some offers that do feature some free spins as additional incentives for new players.

How much money can I get with the 100 deposit bonus?

A 100% deposit bonus gives you a total deposit value worth double your initial deposit. It gives you back whatever deposit you make, up to a certain amount, in most cases £50, £100 or £200. So, if you deposit £50, you will earn an extra £50 in your bonus balance, making your deposit worth £100.

Are there 200% deposit bonuses?

Yes. Other than the standard 100% deposit bonuses, some casinos offer higher-value bonuses up to 200% and above. As expected, a 200% deposit would double your deposit as your bonus balance. This makes your total deposits worth triple the original amount. The same goes for other higher percentage offers.

How long does the 100 deposit bonus UK last?

The bonus expiry duration of a 100 deposit bonus depends on the casino in use. But on average, most casinos often feature 100% bonus offers with up to 3+ days validity after activation.
