The UK online gambling market is highly exciting, offering players a plethora of options to choose from. This notion does not apply to gambling sites and games you can play, but also to bonuses you can claim as a new or existing player. One of the common casino incentives available at UK online casinos is a 100% deposit bonus. If you want to learn more about this offer and the conditions attached, we’ve got you covered.
What Is 100% Deposit Bonus and How It Works?
First of all, we have to say that most casino bonuses are deposit-based, meaning that you must make a payment to unlock them. A 100% deposit bonus is one of these incentives you can redeem upon depositing. Once you have made a qualifying deposit, the same amount will be added to your bonus balance. This type of bonus can be used on the games to your liking, without restriction in most cases.

A 100% deposit bonus is awarded to new customers upon registration with the casino that offers it. In this case, we call it a welcome bonus. Some operators offer a welcome package that can consist of several bonuses, including the one that will double your bankroll. At some casinos, you can claim a 100% deposit bonus as an existing customer. We call such an incentive a reload bonus.
How to Claim 100% Deposit Bonus?
The first step you have to make if you want to claim any casino bonus is to create an account and complete the signup procedure. At the best UK online casinos, it will take you a few moments to provide your personal information, including your name and surname, physical address and email, the city and country of residence and more.

Once you have set up your account, you can go to the Banking page and choose the payment method that suits you best. In the UK, you cannot use credit cards to make casino deposits, so choose from debit cards, e-wallets, pay by mobile options, etc. Make a minimum qualifying deposit and redeem the offer. In some cases, you may be asked to enter the code. Just copy and paste it to unlock the bonus.
Where to Find Best 100% Deposit Bonus UK?
The best deposit bonuses in the UK market are available at trusted, UKGC-licensed online casinos. You can choose them from our list of approved gaming operators or search the Internet yourself. If you opt for the latter, make sure to pay attention to whether the operator holds a valid licence issued by the UK Gambling Commission. However, this is not the only thing you should focus on when looking for a bonus that is worth it.
100% Deposit Bonus Terms and Conditions
What sets a good bonus from the bad one are the terms and conditions attached to it. First and foremost, you should check how high wagering requirements are set and how much time you have to meet them. Besides, you should know that your bets will be limited by the operator while using a bonus. At UK online casinos, the max bet limit is typically set at £3 or £5. In this case, the higher limits are favourable to the player.
What is not favourable to the player is a high wagering requirement or playthrough. At best online casinos, it is set at 30x to 45x. Anything above it is unacceptable. Besides, check the timeframe you have to complete the playthrough. Some operators will give you only 7 days to do it, which is not good for you. At least a month is considered a reasonable timeframe.
Under the terms and conditions, you will also find the list of games with rates at which they contribute to wagering requirements. You will notice that slot machines are your best friends in this quest since bets placed on them count 100%. On the other hand, popular casino classics, whether they are RNG or operated by real-life dealers, contribute at a rate of 10% or 20% only in most cases.
Why Use 100% Deposit Bonus?
As we have already mentioned, a 100% deposit bonus will double your bankroll and fun. This may come in handy if you are new to this form of entertainment, since as a newbie, you may not enjoy the gameplay to the fullest worrying about losing your hard-earned money.
When you use the bonus cash, you can relax and try out different games with no risk involved. Make sure not to wager more than allowed when using free cash. If you wish, you can meet the wagering requirements to turn your bonus into withdrawable cash or simply enjoy free money as long as it is available.
