Best Casino Bonuses | Guide to the Best UK Casino Offers

Play at the top-rated casino bonuses sites in the UK

Looking for the best casino bonuses? Our guide looks at the UK's top casino offers, highlighting free spins, welcome offers, & no deposit bonuses.

Best casino bonuses

Casino bonuses give you cash or credit to use on your favourite games. This means the best ones must be available for the games you care about. 

While there are lots of different bonuses you can get from gambling sites (particularly when you include ad-hoc rewards) there are three main ones you’re likely to see: 

  • Welcome bonuses 

  • Free spins 

  • No deposit bonuses 

You’ll often find these advertised in the header of a site’s homepage. However, it’s always worthwhile checking the promotions page of a casino to learn more about the bonuses it offers. 

Is a bigger online casino bonus always better?

You should never judge a casino bonus solely by how big it is. 

Gambling rewards can offer you the chance to earn large amounts of free spins and top up the deposits you make when you create an account. But they can also come with limitations and place demands on you that make them less appealing. 

These limitations include restricting you to using the bonus on a specific game. The demands can also feature wagering requirements you need to meet to withdraw the winnings you earn from the bonus.

So, before you sign up to a big casino bonus, compare its limitations and demands to those you get from a smaller reward. You may find that the ‘lesser’ bonus is actually better than the larger one. 

How we review the UK’s top online gambling bonuses 

Gambling bonuses are offered by all of the UK’s top casinos. This is because they’re a way of drawing players to a site and then getting them to keep coming back. 

But our reviews aren’t concerned with just the level of bonus you can get — how many free spins are on offer and the size of the welcome bonus you could earn. 

We care about them offering value to players. 

This means that our reviews highlight the wagering requirements of casino bonuses, as this tells you how much of your own money you need to invest to be able to withdraw the winnings you make from the rewards.

Slots are the most popular game at most gambling websites. This means that free spins are often the best casino bonuses offered by the top sites. 

There are a few things to consider when deciding which site has the best free spins offer:

  • How many spins can you get?

  • Are there any wagering requirements?

  • What games can they be used on?

If quantity is what you look for then bgo is the site for you. It offers you the chance to get a huge number of free spins, more than 5x the amount of some casinos. 

If you’re happy to take a lower amount of free spins because you don’t want to have to worry about wagering requirements then PlayOJO is perfect. Its free spins have no wagering requirements, something very few sites can match.

The best casino bonuses give you a chance to get cash or casino credit to play your favourite games. While free spins offer credit, welcome bonuses reward you with cash.

These are the key things to consider when deciding if a site’s welcome bonus works for you: 

  • Amount of the cash offer 

  • Number of deposits required to get the full reward 

  • Wagering requirements of the bonus

The Grand Ivy Casino is the site that has the current best welcome bonus offer. 

You can earn a large amount of cash over the course of three deposits and the wagering requirement of the promotion is pretty competitive – it’s neither particularly high or especially low.

No deposit bonuses are casino rewards that don’t require you to make an initial investment. 

These bonuses are either free spins or a cash amount, with free spins generally the most popular choice for casinos that offer these rewards. 

These are the things to think about when choosing a no deposit bonus: 

  • Is your preference for free spins or a cash reward?

  • Do the bonuses have wagering requirements? 

  • Can I get a bonus for referring a friend to the site?

888 Casino is the site with the best no deposit bonus, with its cash offer a considerable distance ahead of rival casinos.

How do free spins work?

Free spins are the best casino bonuses for players who prefer slots games to table options. 

Free spins work by giving you casino credit to use on slots games. What you need to keep in mind is that many of the offers can only be used on specific titles. 

Wagering requirements is another key part of how free spins work. 

This is because wagering requirements are the amount of money you need to invest at a casino before you can withdraw the benefits of the bonus. 

You can find out all the information you need about how a specific free spins offer works by reading the T&Cs of the promotion. 

How do welcome bonuses work?

Welcome bonuses are rewards casinos give to new gamblers when they create an account. 

Welcome bonuses work by giving you either free spins or cash to use at a site, with the majority of these offers being a cash promotion. 

Deposits are crucial to how welcome bonuses work. 

The reason for this is that to get the full amount advertised you’ll often need to make multiple deposits, with many casinos giving you a different deposit percentage match for the different increments. 

You can learn all you need to know about how a particular welcome bonus works by reading the terms and conditions of the offer you’re interested in. 

How do no deposit bonuses work?

No deposit bonuses are casino rewards you earn without needing to invest your own money.

No deposit bonuses work by providing either free spins or cash to use on casino games, with most casinos offering the former. 

Deadlines are vital to how no deposit bonuses work. 

It’s so important because many casinos will give you a set amount to claim your bonus. The reason for this is that sites aim to entice people with a free offer, then payout as few as possible by making them run out shorting after players have signed up.

Casino bonuses are simple to understand. They’re promotional rewards that casinos offer to new and returning players, so that they choose to wager on their games and not with another site.

But rating bonuses is more complicated than simply picking the highest ones. 

This is because there’s more to bonuses than just the spins or cash on offer. That’s why when we rate casino bonuses for you, we also look at: 

  • Wagering requirements 

  • Deadline for use 

  • Number of deposits required 

  • Any games restrictions

We consider all these things when deciding which sites have the best casino bonuses. The key when choosing which casino bonuses to sign up for is to think about what matters most to you. 

Once you’ve done this, make sure that you check the T&Cs of any bonus to make sure it really offers what you want and expect.

There are some important things you should and shouldn’t do when you’re signing up for the best casino bonuses. 

Do these things when signing up for casino bonuses 

  • Read the terms and conditions

  • Decide if you prefer free spins or cash offers 

  • Set gambling limits when using your bonuses 

Don’t do these things when signing up for casino bonuses 

  • Expect to get free money from gambling sites 

  • Invest more money than you’re comfortable with just to get the bonus amount 

  • Create multiple accounts with sites to try and get more offers 

T&C’s of casino bonuses

It’s vital that you read the T&Cs of any casino bonuses that you sign up to. 

Many sites advertise large cash of free spins offers and it’s easy to think that all you need to do is create an account and then you’ll get your reward. 

The reality is different. 

You’ll need to meet a number of different requirements, some of which may require you to invest your own money at the site to get part or all of the bonus. 

Casinos are required by law to publish the full T&Cs of any reward they promote. You’ll normally find this in the small print of the bonus. 

What are wagering requirements?

Wagering requirements are amounts of your own money that you need to wager before you can get the full rewards of a casino bonus. 

They’re represented as a multiplication of the bonus amount on offer – such as 35x – and you can find them in the terms and conditions of the bonus. 

Using the example of a £100 welcome bonus, this is how wagering requirements work:

  • 10x: you need to wager £1,000 before you can withdraw the bonus  

  • 20x: you need to wager £2,000 before you can withdraw the bonus  

  • 30x: you need to wager £3,000 before you can withdraw the bonus

In addition to this, there are other requirements you can expect from casino bonuses: 

  • Contributing a number of deposits 

  • Making deposits in a specific period of time 

  • Depositing a certain amount of cash 

So, make sure you check the wagering requirement of a bonus before you sign up. If you don’t then you might find you need to invest a large amount of money just to get a small reward. 

Most popular types of online casino bonuses

There are three main types of casino bonuses that you should look for at the best gambling websites: 

  • Welcome bonuses 

  • Free spins

While there are other rewards you can sign up to, these are the most popular casino bonuses. 

Online casino offers to avoid

There’s a trick to spotting online casino offers to avoid – look for the wagering requirement 

These are offers to avoid because they require you to wager large amounts of your own money before you can get the full benefits of a bonus. 

It means that if a bonus has a high wagering requirement then you might end up paying lots of your own cash to get its benefits. 

Why you should look for the best loyalty reward casino bonuses

Great introductory offers are among the most important casino bonuses you can get. You’re rewarded with cash or free spins for depositing your own money, or simply for signing up to a casino. 

But you shouldn’t only look for the bonuses that new gamblers get. 

Why? 

Because you can only get an introductory bonus once from a casino, and that might not be enough of a pull if you want to keep going back to a gambling site – this is where loyalty reward bonuses come in. 

There are two key types of loyalty reward bonuses: 

  1. Casino membership 

  2. Ad hoc promotions 

Many online casinos offer both these bonuses and different ones can excel for either their membership offer or their ad hoc promotions. We’ve picked out the best casino for each type of bonus.
