Types of welcome bonuses at UK online casinos

Every welcome bonus is different. Sometimes, you will get a one-off matched deposit bonus. Other times, you will get multiple deposit bonuses. These will spread across your first few days or weeks at the casino.

The multi-part bonuses tend to be referred to as welcome bonus packages – to distinguish themselves from the one-time-only deals. Some will include a handful of free spins, and others will shower you in them. Others will forgo the usual casino bonus paradigm and offer their players lucrative cashback offers – particularly appealing for casino VIPs.

Below, we've included an explanation of each of the deals you might see included in a UK online casino welcome bonus…

Casino sign up bonus

This one (AKA registration bonus) is a bit of a catch-all term and it can mean many different things. Generally speaking, however, it is a deal that is provided without having to make your 1st deposit. Instead, you can expect something like 50 free spins, £25 in bonus funds or (in the case of sports betting sites) a £10 free bet. There will be a wagering requirement attached or other restrictions. But you won't have to make a deposit in order to start using your bonuses at welcome bonus casinos.

No deposit welcome bonus

This one does exactly what it says on the tin. No deposit casinos ensure players can claim bonus funds without having to make a deposit. Therefore, this is an excellent opportunity for new casino players to play games without risking their own money. However, it's worth noting that, as with a sign up bonus, there will be terms and conditions attached. One of them will almost always be that winnings are considered bonus money and must be wagered a certain number of times before withdrawal.

Free spins and bonus spins

All free spins casinos in the UK must call their offer bonus spins. That's because, as discussed elsewhere, any free spins winnings credited will be considered bonus funds until the player completes the attached wagering requirement. One very rare exception to this is no wager free spins. However, all bonus spins give players a fantastic way to try out some of the best casino slots available. And there's nothing to stop you from winning money while completing the wagering.

Matched first deposit bonus

This is the most common form of casino welcome bonus. Typically it will be written as a 100% bonus up to £200, for example. That means the casino will match your deposit up to that maximum bonus amount. So, if you deposit a maximum of £200, the casino will add £200 in bonus funds, so you can play with a total of £400. Of course, you could also deposit, say, £50 and play with £100 instead. Again, a wagering contribution will apply to the deposit, the bonus or both.

Second and third deposit bonuses

These are almost exactly the same as the first deposit bonus mentioned above. Except that they will give you additional bonus funds on your second and third deposits respectively. (There may even be a fourth or fifth deposit bonus at some online casinos, too!) Just keep an eye on the percentages used. You might well see the percentages drop down from 100% or 200% first deposit bonuses to something like 50% on your second and 25% on your third, for example.

Cashback welcome bonus

This one is quite different and is often favoured by high rollers and VIP players. That's because cashback casinos provide a form of insurance policy against a bad run of form. For example, you might get back up to £500 on any losses over your first week at the casino. So, if you win, all good. But if you lose, you will get some of your money back in the form of additional bonus money. Again, the bonus money must then be wagered a certain number of times before being withdrawn.

Other casino bonuses

There are lots of variations on the above. The online casino bonus money might be tied to live casino games, for example. Or, if the online casino has a sports betting section, then you might qualify for a £50 free bet – either instead of or in addition to your online casino bonus. Loyalty bonuses are another common one. Or you might be able to make a deposit in order to receive high-value bonus spins. Just go through all the casino bonus offers to see which one you prefer.

How to choose the best casino welcome bonus

Please quickly review the lists of UK welcome bonuses we've included above. These should give you a great overview of what's out there. Then, decide what works best for you. For example, do you want a casino deal with plenty of bonus spins? Or would you rather have the insurance policy of a cashback bonus instead?

Alternatively, are you just looking to maximise the bonus funds available by picking the highest percentage deposit match bonus with the largest maximum bonus amount? Or, on the other hand, perhaps you're looking for something that enables you to spread your welcome bonus funds across slots, live table games and sports betting? All are valid ways of going about it. So it's largely down to personal choice.

Once you've decided, we've made it dead simple to sign up, claim an active bonus and start playing those bonus spins. Clicking on any of the UK casino bonus offers on this page will take you directly to the sign-up page of the online casinos. From there, fill in some basic details, make your first deposit (if required) and explore the casino's features.

So, go ahead with that now or continue reading to learn more about online casinos and their various forms of welcome bonuses, bonus spins and other types of bonus credit. We give you the full lowdown on welcome bonus casinos.

How to withdraw your welcome bonus winnings

Linked to the above, you'll naturally want to withdraw any winnings resulting from your bonus funds and your free spin winnings as soon as you can. Just complete the wagering requirement and any other targets within the given time limits.

If you're unsure if you've done everything correctly, contact the customer support team. A team member can tell you exactly what you have left to do. Or whether you have already made the wagering contribution. After that, withdrawing bonus winnings and free spin winnings is dead simple…

First of all, head over to the cashier area of the site. Often, this is located in the player account settings or alongside the deposit options. From there, you should see your bonus or free spin winnings. If so, all you need to do is choose one of the payment methods available from the dropdown menu. Then, enter the amount you wish to withdraw this time and follow any additional onscreen instructions.

See, we told you it was easy peasy! However, most withdrawals at welcome bonus casinos are not instantaneous. For more information, check out our payment methods guide.

How to use casino bonus codes

Whenever a casino bonus requires a bonus code, we include it on the offer. We even simplify copying the bonus code so you won't make any mistakes by typing it in manually. But maybe you're wondering what a casino bonus code is? Here's how it all works at welcome bonus casinos…

UK casinos use bonus codes to prevent everyone from having access to the same deal – or to prevent bots from spamming their offers. So, when you see a bonus code offer on GamblingAuthority, you can be sure you're getting an exclusive welcome bonus. Or at least one that's unavailable to the general population somehow. And applying them is as easy as pie.

Once you've copied the casino bonus code, click the link to the casino's sign-up bonus page. There, you will find a field to paste the bonus code. Then, fill in the rest of the required details, and you'll be up and running in a matter of seconds. After that, enjoy your bonus funds!

The pros and cons of welcome bonuses

While it's perfectly possible to start playing at a UK online casino with your own money, we heartily recommend taking up some of the best casino bonuses available. Here's an overview of some of the other pros and cons…

Pros

  • Sign-up bonus funds are available without making a deposit
  • Additional playing funds during your first few weeks
  • Bonus spins are included for some of the best casino slots
  • Some welcome bonus casinos feature multiple deals
  • Opportunity to try out many different online casino bonuses

Cons

  • Wagering requirements are quite high at some online casinos
  • Free spins might not be included in some welcome bonuses
  • There may be restrictions on what casino games can be played
  • Certain payment methods might be excluded from bonuses
  • Having to be aware that T&Cs apply to your online casino bonus

Understanding welcome bonus terms and conditions

Getting to grips with the often extensive terms and conditions attached to UK welcome bonuses is vital. Arguably, the most important of these regards the wagering requirement. For example, you might see something like bonuses are subject to 35x wagering. That might be confusing for the uninitiated. But have no fear – we will break down the most important elements of these bonus terms for you.

We'll also review the various limitations of different types of bonus wins and max bet restrictions on bonus spins credited to your account. And if you want to gamble responsibly, you'll need to check what T&Cs apply each time.

Wagering requirements at welcome bonus casinos

If you claim a welcome bonus of £100, you might have to play through that amount 35 times to complete the wagering requirement. But what does that mean in plain English? Well, 35 times 100 equals £3,500. So, essentially, this rule says that you must play through (or wager) £3,500 on eligible casino games.

That sounds like a lot of moolah (and it is), but don't forget that you are not simply handing that money to the online casino. It's more than possible to win while wagering that money, so you could come out even further ahead. All that matters is that you risk £3,500 on certain casino games.

Also, it's worth noting that a time limit may be placed upon the wagering requirement. This means that you will only have, say, 30 days to wager the required amount. You can take all the time you want, but some online casinos aren't so generous with their time limits.

So, completing the wagering requirement as soon as possible is worth it. In that way, you can withdraw whatever winnings you have left over and explore all the different games without any restrictions.

Welcome bonus time limits and max win limits

You'll need to make a minimum deposit when claiming your bonus funds in the first place. This won't be much – it can often be as little as £10. But before you do that, have a read through whatever T&Cs apply. For example, when claiming a welcome bonus from a UK online casino, check how long you must play your bonus funds and complete the wagering requirement. Otherwise, your bonus funds might be voided, meaning any winnings will be lost, too.

Also, your bonus funds are separate from cash funds in most instances at welcome bonus casinos. So, we recommend following the rules to the letter to avoid losing out. Another important one at welcome bonus casinos is the max winnings rule. This states that you can only win up to a certain amount with your bonus funds.

The same thing might apply to free spin winnings, too. For example, you have 50 bonus spins for Book of Dead. You can freely play those bonus spins on the selected titles, but you might reach the £100 cap after only playing 30 of those spins, for example. Anything beyond that wouldn't count towards your free spin winnings, and you couldn't withdraw anything beyond that £100.

Still, £100 is a decent sum in anyone's book. It's just a way for welcome bonus casinos to protect themselves from players winning thousands in free spins winnings. So, always check the max free spins winnings rules in the T&Cs.

Welcome bonus game restrictions and percentages

Most slots count towards the wagering requirement 100%. However, many others might be excluded or only contribute a lower percentage. Therefore, it's well worth reading through the full terms and conditions of any casino deal you decide to take up. For example, you might see something like the wagering contribution of video poker or live casino is 5%.

Of course, you can still play video poker to your heart's content. But it's worth noting that it will take you much longer to complete the wagering requirement if you only stick to those games. We recommend using your cash funds to complete the wagering requirement on games contributing 100% to make it less of a slog. This will make things much easier at welcome bonus casinos!

Conclusion

We hope you've enjoyed our guide to welcome bonus casinos. UK players will find welcome bonus casinos everywhere online. That's because they are undoubtedly the ones that draw in casino players. Finding great welcome bonus casinos from the hundreds out there is the difficult part. But if you look over our list of welcome bonus casinos above, you'll be one step ahead of the game. You can also read reviews of our recommended welcome bonus casinos in the same spot. Then, it's just a matter of finding the best welcome bonus offer for you. And, don't worry, we only recommend welcome bonus casinos licensed by the UK Gambling Commission.

Welcome Bonus FAQ

This is a difficult one because everyone is different. However, we've done our best to provide a range of different UK online casinos on this page along with their welcome bonus and free spins on Starburst and other top casino games like Book of Dead, for example. Many of these UK casino sites also offer sports betting and poker, so be sure to read our online casino reviews.

Finding the best online casino bonus in the UK is easy. You just need to decide whether you prefer a large amount of welcome bonus funds, a larger percentage for your qualifying deposit or if you want something like 50 bonus spins credited on your favourite online slots. You might even decide that a cashback offer would be ideal. Check out the deals above for more info.

Yes, as soon as you have an active bonus at a UK casino, you can start trying to win big. The same is true of any free spins bonus. Just note that there may be a max win amount specified in the T&Cs. If that's the case, your bonus winnings can only add up to the max winnings. There may also be max free spins winnings rules in place, too. As always, read if certain T&Cs apply.

As implied by the term "welcome", these types of UK casino bonuses are reserved for new players and are often restricted to one deal per household. So, while you can often find multi-part online casino bonuses as a new player, you cannot claim them more than once. However, there's nothing to stop you claiming sign up bonus funds from multiple UK online casinos.

So long as you meet the minimum deposit or qualifying deposit, the wagering requirement and you keep your bonus funds separate to cash funds, you'll be able to withdraw your bonus winnings and your free spin winnings. So if you have some bonus wins and customer support confirms you've done everything required, you can withdraw your bonus winnings as usual.

We cover this in more detail above, but if that was TL;DR, here's a summary. UK online casino bonuses usually require that you wager around 30-35 times your bonus amount before being able to withdraw any bonus winnings or bonus spins winnings. As for a max bonus bet, that's a separate rule that states you can only bet up to a certain amount with your bonus funds.

It's up to you. And if you want to gamble responsibly, then it's worth considering whether the best casino bonuses meet your requirements or whether you'd rather try to get some bonus spins winnings instead. Plus, you can always play the games with your own cash funds and then be able to withdraw your casino winnings without meeting any wagering requirement.

In the UK, these are the same thing. So, your bonus spins winnings are the same as your free spins winnings. It's just that the UKGC discourages the use of free spins when there are wagering requirements or other rules in place before being able to withdraw any free spins winnings. After all, if you have to meet a wagering requirement then the spins are not "free".
