What are casino bonuses?

Other than attracting and retaining customers, casino bonuses are offered to boost your bankroll. Online casinos that accept Brits offer different types of bonuses, ranging from the welcome bonus to refer a friend offers, as well as ongoing promotions. However, you will be required to spend some of your money before you can withdraw the bonus wins. It is not mandatory to claim for the casino bonuses when you sign, that is why many websites make it optional for customers.

Casino Bonus
There are a variety of casino bonuses that can boost your bankroll. Be sure to read the T&C before choosing one.

How Online Casino Bonuses Work

Casino bonuses work quite in a simple way and can be used by players with all experiences. The welcome bonus is the widely available offer. Though the bonuses may vary at UK casinos, they have a common rule whereby you must sign up before you are eligible to claim. Usually, the registration process is simple and straightforward, and it only takes a couple of minutes for your account to be ready. It is important to note that some casino operators will require you to use a promotion code to claim.

Factors to Consider When Choosing Good Bonus Offers

With so many bonuses offered by online casinos, it can be a hard task for both novices and experienced punters to select the best one to claim. Luckily, we have done the difficult part for you by highlighting some of the key elements to consider. Some of the factors to consider include:

Match Bonus

Match bonuses are calculated on the amount you deposit into your casino account. The most common match is 100%. There is also a max limit to how much bonus you will get on your deposit which varies. Casinos usually write it as in this example: 100% up to £100. In this case, you will get £200 to play with.

Playthrough requirements, wagering requirements or turnover requirements

This is one of the most crucial things to consider when hunting for casino bonuses. It is the multiplier that shows how much you must wager to withdraw your bonus wins. You should apply for bonuses with wagering requirements that are as low and reasonable as possible. We list all wagering requirements for each casino, so it’s easy for you to find the right one.

Expiry Time or Time Limit

Casino operators offer bonuses with set time frames, after which they expire. We recommend that you choose offers that take long before they expire to have a chance to meet the wagering requirements and maximize your chances of winning more.

Eligible games

Usually, only slots are counted against the wagering requirements and be sure you don’t play any slot that is restricted to play on with bonus funds. Some slot machines have been easier to wager the bonus on such as Blood Suckers (NetEnt), Lucky Put (Synot Games) and Bonus Bears (Playtech). Therefore many casinos have lowered the wagering contribution on some slot machines to 75%, 50%, 30% or even 0%.

Bet Limits

All casinos have a bet limit per spin when you’re playing with bonus money. This is to reduce the risk of players winning larger sums and quicker wagering the bonus. The maximum bet limit is usually £5. Be careful not to bet more than what is written on the T&Cs. If you are unlucky and accidentally bet more than the limit, the casino can confiscate your winnings and the bonus.

Winnings Cap or Max Win

Usually, online casinos have a cap on how much you can win when you are playing with bonus money. Read the T&Cs, so you don’t get an unpleasant surprise if you’re winning a lot.

Popular Types of Online Bonus Offers in the UK

There is something for everyone when it comes to bonuses at online casinos. Be it the welcome bonus you are looking for or payment method reward, you are sure to find. These bonuses come with different terms and conditions which must be met by players before the wins can be cashed out. The most popular casino bonuses are divided into the following three main categories:

‘Starter-Perk’ Casino Bonuses

As the name suggests, these types of bonuses are designed to benefit new players when they join online casinos. We recommend players with little gambling skills to go for these bonuses because they don’t involve risking big sums of money. The four main types of bonuses available to new players are:

Sign Up or Welcome Bonus

This is probably the most popular online casino bonus. All the casinos we have listed reward new members when they create an account. The welcome or sign up bonuses are suitable to both low and high rollers, and they come with varying limits and wagering requirements. As aforementioned, it is recommended finding welcome bonuses with as low wagering requirements as possible. It is equally essential to consider the validity of the casino bonus offered before you go ahead to claim it.

No Deposit Bonus

Even though this bonus is not common on UK casino sites, it’s one of the most sought-for by online gamblers around the world. With this bonus, you don’t have to risk your money to play and win. The casino will credit your account with a certain amount of cash or free spins to play a particular online slot immediately after you sign up. Note that this bonus offer can be claimed only once by players and it is always subject to the wagering requirement before a cash-out request is completed. Casinos’ no deposit bonuses are also rewarded like promotional offers at some sites.

Free Spins or Bonus Spins

Normally, free spins may be rewarded by a casino alongside the welcome bonus or as an independent bonus. Many online casinos reward customers with free spins ranging between 10 and 100, to be used within a set period and usually only on specific slots. Remember, some online casinos will reward the free spins only after you have registered and made the first deposit.

Intermediate Casino Bonuses

Once you have claimed the welcome bonus, it opens doors to other more offers from the operator. The extra bonuses are for regular players with some skills and experience in gambling. Nonetheless, we highly recommend that you consider the terms and conditions before claiming any on-going offers. Here are the different types of rewards to expect at an online casino in the UK:

Reload Bonus

Unlike the no deposit casino bonus, this bonus is only available to customers who top up their accounts after the first deposit bonus. The percentage associated with this no deposit bonus is slightly smaller compared to the welcome bonus percentage. This bonus form is often recurring. For example, weekly or monthly.

Cashable Bonus

Some UK casinos will offer bonuses with no deposit as well as deposit bonuses as cashable bonuses. What this means is that you can withdraw the winnings and the bonus itself. For casinos that don’t offer cashable bonuses, the amount that is won from the bonus must be spent on playing different games on the site.

Freerolls Bonus

Though offered by few UK online casinos, freerolls bonuses are awarded to players who participate in tournaments. However, before you claim this bonus, it is essential to understand that the prize pool is fixed and you compete against other real players.

Comp Points

Some casinos will reward your point when you wager on real money live casino games or any other attached games. Depending on the casino, you may be rewarded 1 point for every £10 spent. These points can be redeemed into different rewards, such as free spins, cash, etc. The good thing about this bonus is that you gain points whether you win or not.

Advanced Casino Bonuses

These bonuses are reserved for players who have skills, experience, and sizeable bankroll. If you are looking for a chance of winning big, then you should opt-in for these bonuses. As you expect, these bonuses vary in terms of size and linked games. Below are some of the popular bonuses that can be claimed by high roller players:

Cashback Bonus

Some UK casinos will pay you back on the losses that you encounter. Although this bonus attracts people with all budgets, most casinos reserve it to high rollers only. It may be awarded in different forms such as cash or credit on the casino. Depending on the site, you may be awarded the cashback bonus weekly or monthly.

Casino Cashback Bonus
A Cashback bonus gives you a security or insurance when the loss occurs. Usually you get 10% -50% in Cashback and it depends on how much you play.

VIP Bonus

The VIP bonus is often offered to players who join the VIP clubs of their respective casinos. Usually, these bonuses are available to customers who deposit large sums of money. You may join the VIP program directly after you start playing or via an invitation from the casino operator. Of course, players who acquire the VIP status are entitled to different special treatments like a dedicated personal assistant, invitation to real events, birthday gifts and much more.

Exclusive Bonus

Some casinos reward high roller customers with exclusive bonuses that come in the form of no deposit bonus. The money is credited to your casino account, e.g. $50 for free when you deposit a certain figure. The exclusive bonus is also reserved for high roller players in leading UK online casinos.

Referral Bonus

These are common bonuses and they work in a very simple way. You will receive a certain percentage of people you refer to the casino. However, they must register and deposit funds to their accounts before you receive your share.

How To Claim Online Casino Bonus Offers?

Before you claim any casino bonus, we suggest that you read and understand any terms and conditions attached to it. You may be asked to use a bonus or promo code when claiming your rewards at most online casinos. Here is a step by step guide to claiming your online casino bonus:

  1. From the homepage, go to the casino’s cashier section.
  2. Register a new account or login into your existing account.
  3. Select your preferred bonus, i.e. welcome, no deposit or any other.
  4. Read the terms and conditions as well as wagering requirements.
  5. Choose a payment option to cash out your winnings.
  6. Start playing your favourite casino games.
  7. Complete the playthrough requirements to withdraw.

What are Casino Bonus Wagering Requirements?

We have mentioned the ‘Wagering requirement’ several times. But since it is so important to understand, we go deeper into the subject. If you are new to online casino gambling, you probably have come across the term ‘Wagering requirement’ while searching for bonuses. It tells you the number of times the bonus should be wagered before you are eligible to cash out the winnings. Most people often think that you can withdraw the bonus winnings at any time, only to find that it is not possible. The playthrough requirements help the casino distinguish serious players from mere bonus hunters. The casino rollover requirement is offered in the form of a multiplier. The average wagering requirement in UK online casinos usually ranges from 30 to 60 times the initial bonus amount. But it varies depending on the casino and bonus type.

How to Calculate Wagering Requirements?

It is not difficult to calculate the wagering requirements in online casino bonuses. The following example should help you in determining the rollover of a bonus.

Example: A casino offers a welcome bonus worth £100 subject to 35 times wagering requirements.

To know how much you are supposed to wager before you can cash out the winnings, you need to multiply the bonus by the wagering requirement.

35×100 = 3500

Thus, you need to wager £3500 before you are allowed to cash out winnings from the bonus.

It is essential to understand that casino games contribute differently to the playthrough requirements. Usually, online slots have a higher percentage of up to 100% towards the wagering requirements.

Pros and Cons of Online Casino Bonuses

Online casino bonuses come with both advantages and disadvantages to players as we have highlighted in the next section:


  • Free money: online casinos rewards free money to play with in the form of no deposit bonus. This is available after you have registered.
  • Free Spins: This bonus can be used to play different new slot games and win real money.
  • Loyalty Rewards: you will be rewarded by casinos for playing real money games on their website.
  • Try New Games: some online casinos offer free play bonuses to players to try out the different games they have on their website.
  • Variety: online casinos rewards different types of bonuses to accommodate people with all budgets and gambling experiences.


  • Playthrough Requirements: players must wager the bonus a set number of times before they can withdraw the winnings.
  • Withdraw Limits: some online casinos limit the amount one can withdraw from the bonus wins.
  • Time-frames: online casino bonuses are set to expire after a certain time, could be 24 hours, 1 week or 30 days.

Tips for UK Online Casino Bonuses

The following tips will help people with all gambling experiences to maximize the chances of winning. They include:

  • Always research the games that are linked to casinos before you start playing
  • Read and understand all the terms and conditions attached to the bonuses
  • Find a reputable online casino with appealing bonus offers
  • Choose a fast and reliable payment option to cash out your winnings
  • Don’t fall for exaggerated casino bonuses

Where to Find the Best Casino Bonuses in the UK?

Numerous online casinos accept UK-based online punters. Due to the high competition in the market, these casino operators try to use different incentives to lure new customers. However, a good online casino cannot be determined by looking at the size of bonuses only. The UK-friendly casinos we have listed have been tested and rated by professional gamblers to ensure that they meet all customer demands. Some of the key elements we base on when rating the best include but not limited to; a range of games, software providers, supported transaction options, special promotions, security and licensing and availability of customer support.

The Bottom Line

Online casino bonuses have proven to be a great way of attracting new customers as well as retaining existing ones in an online casino. While casino operators use them to increase the number of customers visiting their site, online gamblers take advantage of them to build their bankroll. As we have mentioned, it is vital to read and understand the different terms and conditions that are attached to any bonus before you claim it. Also, claim for bonuses at best online casinos. The advantage of playing at UK online casinos is that you get bonuses with friendly terms that favour all players. Also, these online casinos support fast payout options that are protected with modern security protocols like Secure Socket Layer (SSL) technology to ensure that customers are safe at all times. These sites are also affiliated to third party firms like BeGambleAware to help people with gambling problems.
