What Is A 300% Deposit Bonus UK And How To Claim One?

Match bonuses are very common promotions in online casinos: Your first deposit gets matched by a certain amount (i.e. 100% casino bonus) and you get a bigger gambling budget as a result. For example, a 100% match bonus will match your deposit 1:1, so if you have 10 GBP to spend, the casino will give you another 10 GBP. The match rate is different at each casino: Sometimes you get 100%, sometimes
200% – you can even find 400% casino bonus UK deals.

As can be understood from this explanation, 300% deposit bonus UK deals are also match bonuses. They triple the amount of your first deposit – for example, if you deposit 20 GBP, you will receive a 60 GBP bonus and play with a balance of 80 GBP. Note that you must make a deposit in order to activate this bonus – it is called 300 first deposit bonus UK for a reason. The minimum deposit amount can be anything: Each casino site sets its own limits. The 300% deposit bonus UK can be seen even in £3 minimum deposit casino UK sites, or you may be asked to deposit at least 10 GBP to activate it. Again, it all depends on the casino.

Claiming this bonus is easy enough: Most of the time, making the first deposit will be enough to activate it automatically. Here is what you need to do, step by step:

Step 1
Find a casino site that offers a 300% deposit bonus UK. Once again, you don’t need to search the internet – just pick one of our recommended casinos in this article.
Step 2
Complete the registration and become a member of that casino. Log in to your account with your credentials.
Step 3
Open the current promotions page and look for the minimum deposit limit of the 300% deposit bonus UK. While you are here, also check for whether a bonus code is needed or not.
Step 4
You are ready to make your first deposit. Make sure it is not less than the minimum deposit limit. And if you need to use a bonus code, you must do so before the deposit.
Step 5
Complete the process and wait for the money to arrive at your account. The 300% deposit bonus UK will activate automatically once that happens. If not, just contact customer support.

Note that this guide can be used to activate any kind of first deposit bonus – for example, you can use it at 200% bonus casinos too.

Things To Know Before Choosing A 300% Deposit Bonus UK


You need to check for two things before claiming a 300% deposit bonus UK:

  • Check the maximum bonus limit. Yes, the match rate is 300% but there is a maximum limit of money you can earn. Don’t expect to win 30.000 GBP by depositing 10.000 GBP – there will always be a limit and this will be clearly stated in the terms & conditions with the following term: “up to”. If the bonus says “300% deposit bonus UK, up to 100 GBP”, for example, you won’t be able to win more than that amount.
  • Check the wagering rate. Like all other casino bonus offers, you need to wager 300% deposit bonus UK deals too. The wagering rate must not be too high – otherwise, it will be near-impossible to complete it. Look for wagering rates in the range of 20x – 40x. If it is higher than that, the bonus may not be worth your time.

What Is The Advantage Of 300 Deposit Bonus UK Offers?

As we mentioned above, match bonuses are common in online casinos: You can easily find a 200% casino bonus UK, for example. But the match bonuses with higher rates are rare – you need to look for them, specifically. A 300% deposit bonus UK will triple your starting budget and give you a great head start: Even if you have only 20 GBP for gambling, you can easily increase that budget to 60 GBP. Or, you can take advantage of a 300 deposit bonus UK slots deal and win dozens of free spins: Each of these spins can bring you the jackpot prize. In short, online casino bonuses give you lots of freebies but 300% deposit bonus UK deals give the most – this is their main (and most important) advantage.

In order to fully maximize their potential, we recommend to combine them with no deposit bonuses. The idea is simple: Use a UK mobile casino no deposit bonus first, find out if you like the casino site or not, and if the answer is yes, make your first deposit to get the 300% deposit bonus UK. And if the answer is no, simply try another casino: We can recommend you lots more.
