Find the Best First Deposit Bonus Casino

Top UK online casinos are in fierce competition for players, so of course, they’d try to attract more gamblers through a casino deposit bonus. However, you should look beyond the appeal of the bonus. You’ll be sharing personal and payment details with the online casino. You don’t want to submit them with a rogue casino that will overcharge you, mishandle your details, or bury you in wagering requirements.

Keep in mind that the best deposit bonus doesn’t necessarily have to be a welcome bonus. Apart from welcome offers, gambling sites usually have a number of regular promotions available to already signed-up players. Most of those also require a deposit. Usually, the welcome offers would be the most rewarding and the heftiest.

Putting Best Casino Bonus with Deposit to the Test

But finding the best first deposit bonus casino doesn’t mean you’ve found the best place to gamble in general. There are a lot of aspects that go into declaring gambling sites as top online casinos, and research is required. When we shortlisted our recommendations where you can find a great casino deposit bonus, we already did the heavy lifting. Those casinos were put to the test and passed with flying colours.

Available Licenses

When going into gambling online, you can’t afford to overlook the licenses of your casino. Of course, having a UKGC license is a must. That means they’ve been sanctioned by the UK Gambling Commission to provide gambling entertainment to you. But it’s also an indication that they’re following the Commission’s guidelines and rules. From there on out, it always looks good if they have an MGA license, as well.

Fair Game Selection

If we’re talking certificates, your casino needs to have one confirming it’s featuring provably fair games. After all, you’ll be using your bonus on these games. It will sting if they’re unfair or rigged. Look at the featured providers. Are they the ones you like or would love to try out? Are there enough games or something’s lacking? We’ve made sure to recommend you casinos with the best games, featuring leading and innovative providers.

Thorough Security

While licenses and certificates are crucial for the gambling site’s legitimacy, you need to pay attention to the security on the website. That includes the available support and applied encryption. SSL protocols indicate that the data you submit with the gambling site – personal and banking, is encrypted. Look out for the padlock next to the website’s address. We’d never recommend a casino that has poor customer support or lacks encryption.

Various Payment Methods

Since the UKGC has a strict ban against gambling on credit, you’ll need the appropriate banking options to deposit. At the best casinos, you’ll find a blend of bank cards, e-wallets, and other prepaid solutions. We recommend you gambling sites with plenty of options. Check out our top recommendations for specific deposit methods and work your way from there. After all, you’ll only be eligible to claim a casino deposit bonus if you make the qualifying deposit.

Casino Deposit Bonus – How to Choose One?

Claiming the best casino bonus with deposit requirements can be challenging at first. With online gambling, the size truly doesn’t matter. Or at least the size of the bonus. Sure, it’s great to claim the biggest offer possible. But casino bonuses, whether or not they require a deposit, come with particular requirements and terms. Unless it’s a wager-free promotion, you’d have to make yourself familiar with those. Even if it’s a wager-free offer, you might face other restrictions related to the casino site payment options, for example.

As you well know, to prevent fraud, some casinos restrict your access to bonuses if you use Skrill or Neteller, let’s say. It’s not always the case, but this is the most prominent example of limitations related to payment methods. In addition, if you’re able to claim a deposit bonus using them, their terms might differ slightly form all other cases. An example of that would be different maximum bet requirements when you claim casino deposit bonuses using Neteller or Skrill.

What matters most is that the attached terms are fair. If you check our recommendations for the best casino deposit bonuses, you’ll notice they have several things in common. They are offered by secure casinos, come with fair wagering requirements, and will not restrict your gambling options, on the contrary. Whether for first-time players or active gamblers at a particular casino, the goal of these promotions is to boost your ability to play. Even the smallest bonuses would be far more worthwhile than the huge promos if their terms are fairer.

Steps to Claim the Best Deposit Bonus

If you’re convinced you’ve found the best deposit bonus, there shouldn’t be any obstacles in front of you now that you’re ready to claim it. The process would vary depending on whether or not this is the first time you’re joining a casino or not. In that case, we’re talking of welcome bonuses. Those you can accept upon your sign-up. In all other cases, we’re talking about regular promotions. They, as you know, come as a deposit match bonus or free spins. Here’s a quick overview of what to do in order to claim them:

  • Navigate to the promotions section of your casino;
  • Go over the requirements of the bonus to determine if it’s fair;
  • Opt to claim a bonus through your player’s dashboard;
  • Enter a bonus code, if required – it will be mentioned in the promotion’s description;
  • Claim the bonus and play.

Even if this isn’t the first bonus you’re claiming from the casino, you’d still have to keep an eye on the attached terms and requirements. Check one of the recommended casinos on our shortlist. We’ve made sure to represent the best deposit bonus UK gamblers can claim in any case and type.

Casino Deposit Bonuses Terms & Requirements

We’ve put together a short overview of the requirements we evaluate a casino deposit bonus against before we decide to recommend it to you. When searching for the best deposit bonus casino sites can offer you, have those things in mind. They’d make a massive difference. Bonuses shouldn’t come with huge risks and limitations. They’re meant to enhance the gameplay and extend it, not bankrupt you because of wagering requirements. If you’re ready to pick the best UK casino deposit bonus for you, check out our latest bonus offers and recommended gambling sites.

Wagering Requirements

Wagering requirements are what will make a particular casino deposit bonus attractive or not. Most casinos have average rollover requirements ranging between 30x and 45x. Lower ones are very hard to find while higher ones might be a deal-breaker. Keep in mind that the UKGC has guidelines on the matter – spins bonuses requiring deposits and having wagering terms will be advertised as extra or bonus spins, and not free spins.

Applicable Time Limits

Another aspect of casino deposit bonuses is their time limit. Especially when talking about promotions containing extra spins, those would be quite constrained. The average time limit for that would be 24 hours. Playable cash bonuses would range between 7 and 30 days, in some extreme cases – up to 60 or 90 days. The worst thing you can sign up for is a time limit that requires you to wager your winnings or bonus within a very short time-frame.

Known Game Limits

The case with extra spins, in particular, is tricky because you can play them only on pre-selected games chosen by the casino. If you’re looking at tons of bonus spins that can be played on a single game, that might not be the best of deals. Whenever spins are more, they are usually spread between several games. In most cases, this dedication relates to specific promotions – of games or different casino game providers.

Eligibility to Claim a Bonus

The one thing that will make you eligible to receive a casino deposit bonus is making the minimum qualifying deposit. Whether it’s upon sign-up or a regular offer, you can’t claim it if you don’t deposit the required minimum, at least. There might be some additional eligibility limitations like the payment method you’re using or your track-record with the casino, but making the qualifying deposit is top of the list. The minimum would be around £20 and slightly vary depending on your casino and the particular promotion.

Restricting Win Limits

If winnings made using your playable cash bonus are limited, something’s fishy. That’s not common practice at online casinos. On the other hand, all extra spins bonuses have their respective winnings limits. The most common one is £100. It’s disappointing that all winnings above that amount will be voided. If you’re looking at even lower limits, it’s quite likely you can find a better casino deposit bonus containing extra spins.

Applicable Payment Method Restrictions

Today, most casinos allow you to use dozens of banking options in order to deposit. You’ll be able to use debit cards, e-wallets, even some prepaid solutions. But as you probably know, when using some methods, you won’t be eligible to claim a casino deposit bonus. The reason for this is fraud protection. These restrictions, if present, will be disclosed in the bonus policy of the casino. We always mention those when reviewing recommended casinos.

Online Casino Deposit Bonus – Diversity to Explore

Making a deposit isn’t the only way you can get a bonus and boost your gameplay. There’s a whole host of other regular promotions at casinos. That’s the best part of playing at a recommended gambling site with generous bonuses. UK players can leverage a variety of promotions, some exclusive to VIP players, others available to everyone. Some of them include:

  • Free Spins: The UKGC defines those as free spins on registration, no deposit required. They should also be wager-free. If a deposit is required in order to receive spins, they will be defined as extra or bonus spins. The downside is that no-deposit spins promotions are extremely rare. It’s even rarer to find wager-free spins to claim, but it’s not impossible.
  • Welcome Bonus: If you check out our recommendations, we believe you’ll find the best casino sign up offers without hassle. Those are briefly discussed in our bonus guide, as they are usually deposit bonuses. In some very rare cases, you can find playable bonus cash or free spins upon your sign-up. They can be either a single bonus or a whole package.
  • Cashback Bonus: Cashback promotions are very attractive but are usually reserved for regular, if not VIP players. They give you the chance to get some money back from your losses. They aren’t major, but some of the top gambling sites provider between 5% and 25% cashback bonuses. Most often, you’ll find cashback offers for live casino gaming.
  • Reload Bonus: Reload offers are a deposit bonus in nature, as well. They are available as regular promotional offers, usually available to all players. In most cases, a bonus code would be required to indicate you want the reload bonus. You can also expect them to be smaller in size than your welcome deposit bonus, for example, and will be time-sensitive.

Deposit Bonus Offers vs No Deposit Bonuses

It’s great people can play with bigger bankrolls when using bonuses. But there’s a significant trade-off, due to the wagering requirements. Furthermore, in the common case, you’ll be transferring money before actually playing at the casino in order to receive the deposit bonus offers. That’s a risk that not all are ready to take. Even the best casino deposit bonus UK gamblers can receive would require that leap of faith. That’s why there’s a considerable demand for no-deposit bonus casinos.

What a UK casino deposit bonus can’t offer is the opportunity to gamble before staking your own money. They’d already be with the casino, and you’d have to wager them at least once before you’re able to withdraw. No deposit bonuses might have wagering requirements, but they’ll definitely give you a better taste of the gambling site. And you won’t be risking a dime. But those are tricky bonuses which aren’t favourable for the casinos, and that’s why it’s quite hard to find them.

Casino Deposit Bonuses – Types to Look Out For

Online casino deposit bonuses increase the bankroll and extend the gameplay. Despite having requirements, players still choose to claim them. They would come in the form of playable cash and/or bonus spins. You could say that the best online casino deposit bonus is a balanced combination of both. Just like the number of spins you can get can vary, so does the amount of playable cash. When we’re talking about it, we’re talking about a particular match-percentage. Another thing to consider is the required minimum deposit to claim a bonus. You can find “deposit £5 get free spins” offers, £10 deposit bonus or 20 pounds deposit promotion for example.

Popular Match-Percentage Bonuses

The 100% deposit bonus is possibly the most popular form of welcome offers. It’s as straightforward as they come. For example, if you deposit £20, you get £20 playable bonus cash. Your bankroll, along with the bonus, grows up to £40. These types of casino deposit bonuses usually have higher maximum amounts since the match-percentage is lower. You could say that the situation is similar to the 200% casino bonus.

That won’t be precisely the same when the match-percentage starts jumping. Though rare, there’s a 300% deposit bonus UK players can opt for. It implies that for a £20 deposit, you’ll receive a £60 bonus. Maximum amounts for these bonuses are lower. But for a truly big deposit bonus, casino sites go further. Remember that we’re still talking about welcome offers. You can find some welcome packages spread over the first four, for example, deposits. That way, you can even claim a 500% welcome bonus, if you opt for every offer of the package.

Regular promotions are usually significantly smaller, in terms of size and match-percentage. Welcome packages, also, don’t have to be claimed in full, you can opt just for a part of them. At the end of the day, the best online casino deposit bonus depends on players’ individual preferences. In our recommendations of top casinos, we’ve made sure to present you with gambling site with various casino deposit bonuses so that you can pick the best option for you.

Do I Win Real Money Using Bonuses?

While deposit bonuses are playable cash that doesn’t belong to you, you can win real money when using them. In order to be able to withdraw this money, though, you’ll have to meet the applicable wagering requirements. Do that within the required time frames, and you can enjoy your rewards immediately.

Are There Certain Bonus Limits & Restrictions?

The most significant restrictions are related to payment methods and winnings amounts. As you can read in our guide, when using some banking methods, you won’t be able to claim a deposit bonus. Another example would be the different requirements for maximum bets made using your bonus balance. Additional limits apply to time frames and winnings, as mentioned.

Do I Need a Bonus Code for Deposit Bonuses?

That depends on the type of bonus. If your deposit bonus is a single welcome bonus, you might not have to submit a bonus code. In all other cases, one will be required to indicate you want to claim the offer. These bonus codes are casino-specific. You can find them in the descriptions of every promotion at your gambling site.

Can I Use Bonuses on Different Devices?

Usually, casino deposit bonuses are the same for both desktop and mobile players. But with the rise of mobile gambling, some casinos decided to further pamper players using hand-held devices. Whether the bonus is desktop or mobile-only, these specific aspects will be clearly stated in the offer’s terms and conditions.

Do Deposit Bonuses Have Disadvantages?

The one major drawback of deposit bonuses is the presence of wagering requirements. You’ll have to clear them before you’re able to withdraw unless you decide to forfeit the bonus and the winnings made from it. That’s an opportunity constituted by the UKGC. If you want to play with the bonus and keep the winnings, though, wagering is inevitable with casino deposit bonuses. If you’re not careful, you might be lured with a great bonus and horrible requirements. Check out our recommendations for some of the most rewarding and fair deposit bonuses available.

Are Free Spins Considered Deposit Bonuses?

The UKGC has very strict guidelines on the topic. Free are only the spins that don’t require a deposit and are wager-free. Those are extremely rare to find. You’re more likely to find extra or bonus spins. They can be either no-deposit (rare as well) or deposit bonuses with free spins.
