What Is A Casino Welcome Bonus?
Before you start your search for the best casino sign up offers, it helps to know what they are. A sign up offer is a promotion exclusive to new customers who register at a casino. This promotion may be a new player welcome bonus, free spins, free play, cashback, or some other type of perk.
The purpose of the offer is to encourage new customers to become real money players. The majority of sign up offers require the player to make their first deposit in order to claim the reward. The bonus, free spins, etc. can be used as real money in the casino. These offers can be an excellent way to start your playing experience at a reputable UKGC-licensed site.
Types Of Casino Sign Up Bonuses
There is more than one type of welcome offer. This is why trying to figure out which ones are the best to pursue can be slightly intimidating at times. Here’s a look at the most common types of sign up promotions you’ll find offered by the most reputable UK online casinos.
- Match Up Bonus Sign Up Offer – The most common of the bunch, A match up welcome bonus is often presented as a 100% match bonus, in which the casino will match your exact deposit up to a certain amount (e.g. 100% Match up Bonus to £200). For instance, if you deposit £50, you’ll get a £50 bonus, for a total bankroll of £100
- Free Spins Welcome Bonus – A free spin welcome offer awards you a set number of free spins (e.g. 100) with a predetermined value (0. £10 per spin). These spins typically must be played on a designated game or games. Sometimes, wins from these free spins are even wager free and without win caps.
- No Deposit Welcome Bonuses – Considered to be one of the best casino sign up bonus promotions available, this offer does not require a deposit for you to claim. Usually, it is a small amount of bonus money (e.g. £20) which can be played on all or select games and is awarded after you register an account. It often expires quickly (e.g. within 1 – 3 days after registration).
- No Deposit Free Spins Welcome Offer – No deposit is necessary to claim this offer. Typically, it is awarded after you have completed registration and is a small number of spins (e.g. 10) that can be played only on select games. It usually expires within 1 – 3 days after registration.
- Free Play Bonus – A typical free play bonus functions like a larger version of a welcome bonus with no deposit. You are given a big bonus bankroll to play with (e.g. £500 – £1,000+) and have only 30 – 60 minutes to use it. Once the time is up, you’ll lose any remaining bonus and will likely need to fulfil wagering requirements to withdraw any resulting winnings.
- Cashback Welcome Offer – This offer basically works like a refund. You make your first deposit and the casino will pay back all or a percentage of losses that you may incur from playing their games. It’s kind of like a “free” trial for the player. You either keep your winnings or are refunded your losses in cash.
- Live Casino Welcome Bonus – As the name implies, these bonuses apply just to games in the live casino. It’s usually a match bonus with your first deposit. This particular promotion is exciting because most welcome bonuses can be used only on slot games and exclude table and card games as well as live casino games.
*Bear in mind that all offers have terms and conditions (T&Cs) and most bonuses are attached to wagering requirements. We’ll explain these requirements in further detail later on.
How Can I Claim A Welcome Offer?
Claiming casino welcome offers is a fairly straightforward process, regardless of the offer type. Here are the main steps to keep in mind when opting to claim a casino sign up bonus:
- Create an account – Register an account with the casino. Be sure to provide valid information when filling out the registration form, because you will be required to send documents that prove your ID and address (e.g. passport, driving license, utility bill, etc.) to the casino. This is part of the casino’s mandatory KYC (Know Your Customer) checks to verify your identity.
- Choose the bonus you want to claim – Once signed in and fully verified, choose the promotion you would like to claim. Usually there is only one, but sometimes there are multiple casino welcome bonuses. If there are multiples, investigate each and choose the one you like best.
- Read the Bonus T&Cs – After you know which offer you want, read its terms and conditions in full before claiming it. T&Cs tell you how to claim the offer, what you get, and what you have to do to be able to withdraw the bonus and/or resulting wins, etc. Familiarizing yourself with the T&Cs will help you to develop a plan of action on how to best clear (fulfil any playthrough requirements) the bonus before it expires.
- Activate the offer – Trigger the bonus by following the activation rules. This may include opting in or using a bonus code. You will also be required to make a minimum deposit. The bonus funds you are awarded will be held separately from you real money balance. If, after completing the steps to trigger it, you don’t see the bonus at this point, reach out to the casino’s customer support before playing to make sure everything has been properly activated.
- Start fulfilling wagering requirements – Once activated, you’ll only have a certain amount of time (e.g. 7 days, 30 days – depends on the casino) to use the bonus and fulfil any related wagering requirements. If you fail to clear the bonus before it expires, you will lose any remaining bonus and wins tied to it
- Track your progress – Tracking the progress of your bonus funds from your account can help you stay on top of your wagering requirement fulfilment strategy. Most casinos have a tracker that lets you see how much of the bonus has been cleared and how much time you have left to clear it. Just keep in mind that the progress displayed isn’t always in real time.

Terms And Conditions For Welcome Offers
Just like online casinos, not all casino welcome offers are created equal. This means that the requirements to claim and clear one offer may not be the same for another. The reality is that things can go wrong if you choose to ignore or gloss over the terms and conditions. That’s why it’s always important to read the full T&Cs, or at the very least familiarise yourself with the rules that relate to activating the offer, what you will receive, and what you are agreeing to.
Understanding the following key aspects of T&Cs can make a difference when claiming your new player welcome offer:
- Minimum deposit – This term informs you the minimum amount you must deposit to qualify for the offer. If the minimum deposit is £10, for example, you will need to deposit at least £10 into your account to receive the offer. You cannot simply deposit £5 and expect to activate the bonus.
- Eligible payment methods – Find out if the payment method you’d like to use is eligible for the bonus. It is not uncommon for only debit cards to be valid for these offers. Credit cards are not an option for UK players and eWallets, such as PayPal, Skrill and Neteller, are typically excluded from welcome bonuses.
- Playthrough requirements – Most offers, including even the best casino welcome bonus, are tied to playthrough requirements, also known as wagering requirements or turnover requirements. These requirements mean that the bonus (or in the case of a free spins bonus – any free spins winnings) must be staked a certain number of times on eligible games before you are able to withdraw any reaming bonus and bonus-related winnings. For instance, if you receive a £50 Bonus that has a wagering requirement of 40x, you must stake a total of £2,000 (40 x £50) before a withdrawal can be made.
- Game eligibility – Not all games offered by the casino will be eligible for the offer. There may be restrictions on both the games you can play with your bonus (e.g. free spins are valid only for certain slots) as well as restrictions on which games count toward fulfilling playthrough requirements. Some games will count 100% towards fulfilling bonus wagering requirements, others may count for less (e.g. 10% all roulette games), and some won’t count at all. Don’t expect to be able to play whatever game you wish to use or clear the bonus.
- Maximum bet amount – Usually you can only bet up to a certain amount when using your bonus (e.g. £5). This ensures you cannot simply make a single wager and claim you have fulfilled the wagering requirements.
- Maximum winnings – Some deposit bonus offers, no deposit offers, and free spins offers have win caps. This means that you can only withdraw up to a certain amount of the winnings that may result from these offers. For instance, if the win cap is £100, if you were to win $300 with your bonus, you’d only be able to withdraw £100 after fulfilling any applicable wagering requirements.
- Validity period – You only have a certain number of days to use your bonus and complete wagering requirements once it is active. For instance, most match deposit bonuses must be used within 7 days of activation before they expire, while many free spins bonuses expire within 24 hours of activation. As for wagering requirements, its common to have 30 days to fulfill requirements from the point of bonus activation. That being said, some validity periods are much shorter, with wagering requirements needing to be fulfilled within as little as 7 days.
- Withdrawing before clearing a bonus – Any legitimate UK casino will allow you to withdraw from your real money balance at any time. However, in most cases, doing so while a bonus is active, will forfeit the bonus and any bonus-related winnings.
Things To Consider When Searching For The Best Welcome Bonus Offer
Before deciding on a casino welcome offer, there are a few things to think about to ensure that you’re not only claiming the best offer, but that you’re also getting it from the best UK online casino.
- Credibility of the online casino site – Check to make sure the casino is licensed by the UK Gambling Commission (UKGC). UKGC licensed sites must comply with strict rules that ensure fairness, transparency, security, and player protection.
- Available payment options – Check to see if the online casino offers your preferred payment method and that this method is eligible for the online casino sign up bonus you wish to claim. Additionally, ensure that the casino has a prompt withdrawal policy.
- Wagering requirements – Check the wagering requirements of the offer. Whilst you will come across wager-free welcome offers every so often, those are rare so its best to look for low (35x or below) or mixed wagering requirement offers.
- Win caps – Check for win limits. Many online casinos don’t enforce win caps and those that do are typically fair about them. You’ll likely find that win caps are typically a part of no deposit offers (where the casino takes on most of the risk).
- Customer support – Check to ensure that customer support is reliable and can be easily accessed during the time of the day (or night) that you most enjoy playing and/or are intending to claim your bonus. If something goes wrong, you need to make sure issues can be resolved quickly.
- Platform availability – Check to make sure the casino you like is compatible with your preferred playing platform (desktop, mobile or both) and that the welcome offer you wish to claim is also available on this platform.
- Make sure the bonus is right for you – Check to make sure the best casino sign up offers that appeal to you are the most ideal for the type of iGaming experience you want to enjoy. For instance, if you love table games, you likely won’t get much satisfaction out of a bonus that can only be used on slots. Also, be sure check the validity period of the offer to make sure you’ll be able to clear the bonus in time to withdraw it.
Conclusion
There may be many types of online casino welcome bonus offers available, but discovering the ones that are the most ideal for you is simply a matter of knowing what you like, reading the applicable key T&Cs, and choosing a reputable casino.Need more help finding the best casino sign up offers?
