Types of UK Casino Bonuses

Each casino bonus has its own uniqueness to it – they all come in different shapes and sizes. There are pros and cons to each one, too, and it isn’t easy to pick when there are so many available to you. Let’s run you through the different types of casino bonuses so that you can understand them better.

Free Spins

Video slots have been rising in popularity over the years, and so too have free spins bonuses. You’ll come across numerous offers of free spins either on their own or as part of a welcome bonus package, typically alongside a deposit bonus. Many UK casino bonuses tend to offer this type of offer on games such as the Starburst slot from NetEnt or Book of Dead by Play’n GO. These are 2 very popular UK video slots.

But casinos also move away from these 2 typical choices to include free spins on other slots such as Blue Wizard or Gonzo’s Quest. It’s a great chance to test some of these slots if you’ve not yet played them, especially if they’re part of a free welcome bonus where no deposit is required.

You’ll find that no wager free spins are increasingly popular. This allows you to keep what you win when you play a popular slot game. The offers tend to be on the slots mentioned above too.

No Deposit Bonus

These are pretty rare these days, but no deposit bonuses still exist. The amount offered on these promotions is small, but it’s always a great chance to use this casino bonus to test out a new slot. Furthermore, there are a few that come with no wagering requirements, which is always great to see.

Deposit Bonus

This is arguably the most popular offer on the market. A lot of the best casino welcome bonuses are usually a percentage up to 100% or 200% of your first deposited amount, and some of the leading deposit casino bonuses like this can spread over 2, 3 or even 4 deposits.

For example, a 200% casino offer for new players may be available with a certain operator. If you deposit £50 initially, you will get £100 extra to play with.

Typically, maximum limits are attached, such as an offer of up to £50 or up to £100, but the top casino bonuses come with fair and attainable wagering.

Many casino welcome bonuses often include free spins as part of their sign-up offer, so make sure you keep your eyes peeled for those.

Reload Bonus

Casino reload bonuses are very similar to your typical new customer offer, but they’re usually available to existing players and often have a lower percentage attached to them. It’s simply a way of encouraging players to play more and acts as a reward.

Using it is a great way of getting comfortable at a particular casino rather than moving on to a new one. You may need a bonus code with these, you may not, but they do tend to have lower wagering requirements than the best casino offer from a new operator, which is a big plus. These kinds of promotions include:

  • One-time reload bonuses
  • Daily reload bonuses
  • Weekly reload bonuses
  • Monthly reload bonuses

Cashback Bonuses

These aren’t too common nowadays, but some UK cashback casinos will give you back a percentage of your losses over a certain period. This can be over 24 hours, a week, or even a whole month.

Mobile Casino Bonuses

As more and more people switch to a mobile-first way of betting and established and new online slot sites improve their mobile betting experience, it’s only natural that you’ll see mobile casino bonuses around as operators want to encourage you to utilise your mobile for convenience.

Some UK casino bonus sites even offer an exclusive promotion just for mobile players by not making it available to desktop users. LeoVegas bonuses are a good example of this, as they take a mobile-first approach and often have smartphone and tablet bonuses running. Although not always, these can also have lower wagering requirements attached.

But it’s worth noting that it’s not just the mobile promotions that can be claimed. Many of the best casino bonuses can be claimed on mobile as well as on a desktop rather than one or the other.

What Makes a Good Online Casino Bonus?

With not too much to choose between the best casino bonuses on the market, it’s not always easy to identify which ones are better than others. You need to go deeper and look at the following:

  1. Wagering Requirements
  2. Maximum Payouts
  3. Minimum Deposits
  4. Deposit Restrictions
  5. Expiry Dates
  6. Country Exclusions
  7. Eligible Games
  8. Bonus Codes

There might be a nice-looking casino bonus offering a 100% deposit of up to £250. While this looks great on the surface, you dig a little deeper to discover that the wagering is set to 75x, you can only deposit with a debit card, and winnings are limited to £50. This suddenly becomes one of those casino offers you want to avoid.

Let’s expand on the above points to help you understand exactly what to look out for with new casino bonuses.

Wagering Requirements

Some of the best casino bonuses have no wagering requirements, which is great, and there are some out there. But most of them will, and it’s important that you understand them fully because there comes a point where a certain figure is simply unrealistic and very difficult to achieve.

Let’s use an example. You’ve just registered and have claimed a new casino bonus that offered you £100.  Here’s a useful table to show how much you need to wager to meet certain wagering terms listed:

Wagering Requirement Wagering Amount
1x £100
5x £500
10x £1,000
20x £2,000
30x £3,000
35x £3,500
40x £4,000
45x £4,500

As you can see, the higher it gets, the more unrealistic the overall bonus becomes. Many operators will tend to be around the 35x or 40x mark. Anything over that would start to become unattainable, and there are some casino bonus sites out there that offer 60x and above, so that’s why it’s always essential you understand the wagering terms.

Maximum Payouts

Many casino bonuses these days have a maximum limit set on any potential win. Every casino is different, but we’ve seen values anywhere from £25 up to £500. It’s great if you want to find an offer with no limitations, but there are few and far between nowadays.

The maximum win is typically set to £100 at many of the best casino bonus sites, but make sure you understand everything before committing.

Minimum Deposits

Most of the best online casino bonuses require a deposit of at least £10 or more. This is the most common value, but we have also seen minimum initial deposit levels set at £20 or £50. With promotions that reward you for a 2nd, 3rd or 4th deposit, you’ll be required to deposit more than once. However, some no deposit bonuses around won’t require a deposit at all for you to claim the offer.

If you want to deposit under £10, check out our minimum deposit UK casinos. You can deposit as little as £1 and find a list of casino bonuses where you need to deposit £10 or less.

Deposit Restrictions

It’s important to check the eligibility requirements and make sure you’re happy with the options available to you as some don’t include popular e-wallets like PayPal, Skrill or NETeller. Even casinos with Apple Pay might not allow deposits with the iOS payment method for the initial offer upon registration.

If this is the case, our advice would be to use another payment method for the deposit bonus and then switch to your preferred method after that. You should bear in mind that e-wallet payment methods are normally the quickest to cash out so if this is important to you, you need to play at a fast withdrawal casino in the UK.

Expiry Dates

There will always be a time limit on your casino bonus. Whether it’s 24 hours, 3 days, 7 days or maybe even 30 days, you won’t come across one without an expiry date. Make sure you take note of the timeframe, as you will lose any bonus you don’t use in time.

Country Exclusions

We’re just focussing on UK casino bonuses here, but that doesn’t mean there aren’t any country restrictions here because there are. If you live in Northern Ireland, there will be some promotions you simply cannot get. The Isle of Man is often in the same boat, so double-check the offer if you like outside of England just to make sure.

Eligible Games

Wagering contributions vary and must be considered with any casino offer. For example, playing progressive slots when they only contribute 10% to the overall wagering requirements is not the way to go, as it will take you 10 times as long as a slot that contributes 100%.

Here’s one example of the wagering contributions you may come across in the Terms and Conditions of some of the latest casino bonuses:

  • Slots = 100%
  • Blackjack = 25%
  • Roulette = 25%
  • Baccarat = 10%
  • Video Poker = 10%
  • All Other Games = 0%

Bonus Codes

Some of the best casino sign-up bonuses will come with a bonus code attached. You will need to make sure you enter this when depositing or registering. If you need one but fail to enter it for whatever reason, get onto customer support, as they may be able to add it for you on their end.

Best Casino Bonuses FAQs

What are the best casino bonuses for 2023?

More and more casino bonuses are being added as the year goes on. With new casinos coming into the fold or simply with established operators switching things up, there’s always something for everyone. We’ve listed the best casino bonuses around on our page.

Are casino bonuses worth it?

Most casino bonuses are certainly worth your time and effort. Not only do they provide you with a reward such as a deposit bonus or some free spins, but it’s also a great opportunity to use these kinds of offers to try some games you may not have necessarily played with your own funds.

What online casino has the best bonus sign up bonus?

Casushi and Duelz Casino both have great sign-up offers. It’s difficult to know which casino has the best welcome bonus or other bonuses once you’re an existing player. That’s where we come in. Choose from the bonuses listed on this page.

What is the best way to claim an online casino bonus?

If it’s a welcome offer, you need to register, deposit, possibly enter a bonus code and play through any wagering requirements. It might be slightly different with ongoing promotions once you’re an existing player.

How do I turn my casino bonus into cash?
All casino bonuses come with restrictions. To turn your bonus into cash, you need to complete the wagering requirements within the set timeframe. There are also other things to consider including minimum deposit, payment method use and max bet limits.
Which online casino has the biggest welcome bonus in the UK?

There are plenty of top casino offers at UK casinos, but it’s difficult to pinpoint who has the biggest as there are so many other parts to consider. You might see an operator with a £1000 welcome offer. However, the wagering could be 75x for example. So another operator with a £200 bonus and 30x wagering becomes more appealing due to the lower wagering. Just because a casino offers a huge amount, it doesn’t make it the best.
