Additional Info About Promo Codes at a UK Casino

Now that we’ve covered the most common forms of promo code bonuses available, we can get into the nitty gritty of what makes these deals worthwhile and how to spot a legitimate offer. The next couple of sections will expand upon these topics, so read on to learn more. Alternatively, you can skip ahead to our frequently asked questions.

Why Use Casino Bonus Codes to Claim Bonus Offers?

Given the fact that there are so many bonuses available that don’t require codes, you might find yourself asking “What’s the point of using bonus codes anyway?” In short, codes exist to give customers more options and allows casinos to appeal to a broader player base. They’re also known as bonus vouchers.

For instance, codes are a simple way to launch and promote limited-time offers, that otherwise would not appeal to new players or would go largely unnoticed by loyal players. It’s an inobtrusive, totally optional way for players to access greater rewards, should they wish to do so.

In this regard, bonus codes are a great way to reward loyal customers. It’s often difficult to track down codes unless you’re keeping a close eye on an operator’s promotions page or social media feed, so access to codes rewards players for their brand loyalty and awareness.

The Steps to Claim a Bonus using a Bonus Code

If this is your first time using a bonus code to avail of an offer, don’t fret. The process is exceedingly simple, and typically follows the same three steps across all operators. For your convenience, we’ve outlined those steps below:

1
Choose a Casino

Choose a casino and/or bonus that appeals to you from our select rankings.

2
Create an Account

Create an account by clicking the “register” or “join” button and filling the registration form.

3
Enter the Code

Enter the code into the available code box, which is often found alongside the available payment methods.

Naturally, there are exceptions to every rule, so while the above steps will largely be universal, we still recommend that you pay careful attention to the terms and conditions of your chosen casino. It is here that you’ll learn about any restrictions or limitations placed on the offer.

The terms and conditions will also clue you into which games are excluded from or included in the offer, any wagering requirements you will be expected to meet, or any behaviours on your part that might exclude you from opting into the deal.

What Are the Characteristics of a Good Bonus Offer?

For many newcomers to the online casino scene, it can be difficult to ascertain which sites are worth visiting and which offers are legitimate. To help you on your quest, we’ve outlined some of the most important factors to look out for below.

Serious Offers Come from Licenced Casinos

If you’ve read any of our other pages and articles, you’ll know that player safety is always our number one priority. While many bonus offers online seem appealing, there are some shady sites that use offers to lure players into a scam. A good way of avoiding scams is by looking for a valid licence.

Licences are issued by the official state gambling regulator in each country or region. For the UK, this is the Gambling Commission. Sites are only issued a licence from the GC once they’ve met the regulator’s high security and safety standards. For a full overview of sites licenced by the GC, check out our list.

You can find licence information by scrolling to the bottom of your chosen casino’s page. You can also look for other security measures, such as certificates of valid encryption software. You can do this by clicking the small lock icon in the left corner of your browser’s address bar.

Rules and Conditions

As with all things in life, it’s a good idea to read the fine print before signing up for a bonus. One reason for this, is so that you can get acquainted with the deal’s wagering requirements. This refers to the number of times you’re required to wager the value of your deposit and/or bonus before you can withdraw. Perhaps you could find a no wagering bonus.

Other important terms include deadlines and periods of validity. This is the window of time in which you can meet the wagering requirements before the deal becomes void. Finally, the terms will also let you know of any wagering maximums, which might also delay your progress to meeting the requirements.

You Should Be Aware of These Conditions:

Allowed Payment Methods

When selecting your bonus offer, you might find that some payment methods are excluded from triggering the deal. This is not always the case, but it’s worth checking the terms and conditions ahead of time to make sure your favoured method is available. Here’s a list of the most common payment options:

There are a couple of important things to be aware of when making payments at online casinos. For starters, you’re often required to use the same method for withdrawals as you did to make your deposits, whenever available. This is an anti-money laundering measure used by many operators.

You’ll also find that most payment methods have different minimum deposit requirements, and the processing time could be longer or shorter depending on the option you choose. Therefore, for the sake of player comfort and accessibility, the best casinos will always have a broad range of options.
