Types of Welcome Bonuses for UK Players
Every welcome bonus is different. Sometimes, you will get a one-off matched deposit bonus. At other times, you may receive multiple deposit bonuses. These will spread across your first few days or weeks at the casino.
The multi-part bonuses are often referred to as welcome bonus packages to distinguish them from one-time-only deals. Some will include a handful of free spins, and others will shower you with 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
No deposit welcome bonus
Free spins and bonus spins
Matched first deposit bonus
Second and third deposit bonuses
Cashback welcome bonus

How to Withdraw 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 whether you've completed everything correctly, please get in touch with the casino's customer support team. A team member can tell you precisely 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, head 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, select one of the available payment methods 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 Welcome Bonus Codes
Whenever a casino bonus requires a bonus code, we include it on the offer. We simplify copying the bonus code to prevent mistakes when 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 is somehow unavailable to the general population. 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 remaining required details, and you'll be up and running in just a matter of seconds. After that, enjoy your bonus funds!
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 those unfamiliar with the concept. But have no fear – we will break down the most essential 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 the terms and conditions (T&Cs) that apply each time.
Wagering Requirements at Welcome Bonus Casinos
If you claim a £100 welcome bonus, you may need to wager that amount 35 times to fulfil 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 that you could come out even further ahead. All that matters is that you risk £3,500 on specific casino games.
Additionally, it's worth noting that a time limit may be imposed on the wagering requirement. This means that you will only have, say, 30 days to wager the required amount. You can take as much time as you want, but some online casinos aren't as generous with their time limits.
Therefore, completing the wagering requirement as soon as possible is worthwhile. In that way, you can withdraw whatever winnings you have left over and explore all the different games without any restrictions.
Welcome Bonus Time 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. However, before you do that, please review the relevant Terms and Conditions. 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 may be voided, meaning any winnings will also be lost.
Additionally, your bonus funds are typically separate from your cash funds in most welcome bonus casinos. Therefore, we recommend following the rules to the letter to avoid any losses. 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. Therefore, always check the maximum free spins winnings rules in the Terms and Conditions.
Welcome Bonus Game Restrictions and Contributions
Most slots count towards the wagering requirement 100%. However, many others may be excluded or contribute only 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. However, it's worth noting that completing the wagering requirement will take you much longer 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!
