Best Deposit Bonus Casinos

Get real value for your hard earned money when you play at the best deposit bonus casinos in the United Kingdom. These casinos offer generous welcome bonuses, no deposit bonuses, reload bonuses, cashbacks, free spins and so on.

How Do Online Casino Bonuses Work?

Online casino bonuses are given for two main reasons. One to attract new players and to reward both new and existing players. Some casinos reward players for everything they do on the site, starting from sign up to depositing funds, playing regularly, referring friends and so on.

However, casino bonuses come with terms and conditions. These terms must be met before players are allowed to withdraw winnings made through the bonuses. It includes the wagering requirement and game contribution of games.

In some casinos, bonuses are optional, meaning that players can choose not to claim the bonus. Since the conditions are tied to the bonuses, players may decide against claiming such bonuses.

Online Casino Bonuses for New Players

No doubt the welcome bonus is popular among casino players. However, many players do not know that they can enjoy casino bonuses even after their first deposit. Here, we will discuss all the common types of casino bonuses available to UK players and how they work.

Welcome Bonus

The welcome bonus is the most popular casino bonus. Its primary aim is to entice new players to register and make a deposit with the casino. The bonus is a percentage of the deposit, most commonly 100%. However, this casino sign up bonus usually comes with a stringent wagering condition, and there is a maximum amount you can claim. Also, you may not be able to use the bonus to play many table games and some slots. Some casinos offer this bonus more than once, but at a different percentage. For instance, a casino welcome package may include the following:
  • 100% of the first deposit up to £100
  • 50% of the second deposit up to £200
  • 25% of the third deposit up to £200 and
  • 100% of the fourth deposit up to £75

No Deposit Casino Bonus

No deposit bonus is given to players immediately after registration. This deposit does not require any initial deposit before you can claim it. Its primary aim is to encourage players that want to play for real money but are not ready to take risks. You can use a no deposit bonus to familiarize yourself with gambling without risking a dime. However, no deposit bonuses are usually small and also have stringent conditions.

Monthly Bonuses & Promotions

Monthly bonuses are kinds of promotions casinos usually do to celebrate occasions. However, it can be given even without anything in particular to celebrate. The free casino bonus is usually given to players that made a deposit in the month. It can be a fixed amount or a percentage of your first deposit in the month. As a reload bonus, monthly bonuses wagering conditions are usually easier to meet than those of a welcome bonus.

Game-specific Bonuses

Game-specific bonuses are usually given to promote a particular game. If a casino operator is introducing a new slot game, it may give bonuses to players that can be used to play only the slot game. That will make many players try the game, and some may eventually add it to the list of their favourite games.

Reload Bonus

A reload bonus is given when a player makes a subsequent deposit after his first deposit. It is to reward players for their loyalty and also to encourage them to keep on making deposits. If not for reload bonuses, many casino players will be moving from one casino to another just to claim the welcome bonus. However, since you can stay in one casino and be claiming bonuses as you reload your account, the best deposit bonus casinos use to secure players’ loyalty. This bonus may be given multiple times.

A reload bonus is usually smaller than the welcome bonus. Also, its wagering conditions are usually easier to meet.

100% Match bonus on your deposit

A 100% match bonus is a bonus that is equal to the amount you deposited. If a casino offers you a 100% bonus on your deposit, it means if you deposit £200, you will be given 100% of the amount, which is also £200. Hence, you will have £200 + £200 making £400 to play.

Bonus Codes

Since it is not compulsory for a player to claim a welcome bonus or any other type of bonus, some casinos usually use bonus codes. The code will be available to their players, who will have the option to use the code when they are making a deposit to claim the bonus or to ignore the code to reject the bonus offer. A bonus code can also be used to restrict the bonus to a particular geographic area.

Free Spins/Extra Spins Bonus

Like a cash bonus, a casino may give free spins. The spin can be used to play all or selected games. Each spin will be equivalent to a predetermined amount. However, there is usually a maximum amount you can win from a free spin, and winnings will be subjected to a wagering condition.

£5-pound deposit

A £5-pound deposit offers a bonus to players that make a minimum of £5 pounds. In most cases, this will be the minimum deposit possible on the casino site. However, some UK casinos may accept a lower amount of deposit from players that are not interested in claiming any bonus.

£10-pound deposit

Like the £5 pound deposit, a £10-pound deposit is a bonus offer given to players that have made deposits of a minimum of £10 pounds. Players with lower deposits may be allowed to play in the casino but will not be entitled to a bonus.

Bonus Wagering Terms and Condition

Casino bonuses are not just given for free, they come with a price known as terms and conditions. These T&Cs and their importance are explained below:

Bonus Value

The bonus value is the maximum amount you can claim as a bonus. If a casino gives a 100% match bonus up to a certain bonus value, even if you deposit above that amount, you may not be able to claim more than the value.

Wagering requirements

Wagering requirement is also known as playthrough requirement. It is the number of times that a player must wager his bonus amount, or bonus + deposit amount, to be able to withdraw winnings made from such bonuses. For instance, if a casino gives a 100% bonus with a wagering condition of 20 times the bonus and deposit. It means a player that deposited £100 pounds will get a bonus of £100, taking his total deposit + bonus to £200. Now, before the player can withdraw from his casino account, he must play at least £200 x 20, which is £4000.

Maximum win

A casino usually sets the maximum amount you can win when you play with bonus money. Even if you win beyond this amount, you will only be credited the amount. It is important to understand this before accepting a bonus from a casino. Sometimes, it might be better to go for a smaller amount of bonus that gives you wider freedom to win than a big bonus that restricts your winning chances.

Minimum and Maximum Bet

Some casinos do give conditions for your minimum and maximum bet when you are betting with a bonus fund. In some cases, they may state that your maximum bet cannot exceed a certain multiple of your minimum bet. Also, a casino can make a maximum bet a fraction of the bonus claim. If the maximum bet cannot exceed 20% of your bonus, that means if you claim a bonus of £100, the maximum bet you can place at a time will be £20.

Payment Method Restrictions

In order to prevent money laundering and other financial crimes, many casinos usually insist on the banking option you choose for your deposit to be also used for withdrawals. The only exception is if this option is not available for withdrawal.

Game Restrictions

Most casinos do not allow bets placed on table games and live dealer games to count towards meeting wagering conditions. In most cases, you will be allowed to use your bonus and free spins to play only slot games. Even some slot games may not count towards meeting the wagering condition. Another game restriction when you claim a bonus is when a game counts but is not 100%. A casino may count only a certain percent of the amount you wager on some games in fulfilling your wagering condition. For instance, if a game contributes only 70% to a wagering condition, it means a wager of £20 on the game will only be counted as £14.


Casino bonuses do have an expiry time. In most cases, free spins must be used within 24 hours, or you will lose them. Cash bonuses may have an expiry date of 30 days, within which you must use them. If you didn’t use them within that time, you would lose the bonus and any winnings you earn from the bonus. Therefore, it is essential to claim only a bonus you know you can use and fulfil its wagering conditions within its active time.

Betting Limit

The betting limit is one of the restrictions online casinos usually place on bonuses. The limit can be general to all games or specific to a group of games. For instance, a casino may restrict betting to a maximum of £10 on a slot machine and £20 on a table game. Some may not give different conditions; rather may restrict all games to a fixed maximum bet.

It is important to understand this so you can calculate how many times you will have to place bets before you meet the wagering condition. It is always advisable to accept only the bonus if you are confident that you can meet its condition.
