Although playing at online casinos should be fun, from time to time there can be a reason to make an official complaint. When that happens, it’s often hard to know where to start, so this article is here to help.

We’ve compiled full step-by-step instructions on what you should do in these circumstances, along with contact information for the relevant third-party bodies. While we can’t guarantee that your complaint will be resolved in your favour, by following the guidance on this page, you should ensure that you get a fair hearing, provided you are playing with a licensed operator.

Before You Make a Complaint

Before making an official complaint, it’s a good idea to make 100% sure that your complaint is valid, as anybody can make a mistake. Doing the following may just save you some time and energy.

Have You Double-Checked the Terms and Conditions?

Is the complaint about a promotional offer? If so, double-check the terms and conditions to ensure that you definitely qualify for the offer. If the complaint isn’t about an offer, check terms regarding maximum payouts and the like.

Have You Tried Any Basic Troubleshooting?

Occasionally, problems can be resolved simply by logging out and back in, clearing cookies, or waiting a few hours for a technical glitch to resolve itself.

Have You Contacted the Casino’s Customer Support?

The quality of customer support can vary, even at the best online casinos in the UK. However, it is always worth discussing any problems with the operator’s customer support team first before escalating it.

How to Make an Official Complaint About a UK Online Casino

If you are sure that you want to escalate a complaint, the first thing that you’ll need to do is register the official complaint with the casino in question by contacting their customer support team.

Even if you have no expectation of them resolving the issue in your favour, this is a box that you’ll need to tick before you can escalate it to a third party. You should also request a complaint or case number.

Once you’ve done this, you’ll have two options, depending on the specific complaint:

  • Take it to IBAS (RECOMMENDED)

IBAS (or the Independent Betting Adjudication Service) is an Alternative Dispute Resolution service for the UK. By heading to their website, you can use their ‘claims wizard’ to find out if they can potentially help you.

If you have a case, you can log a claim and somebody will be in touch to guide you through the process and, ultimately, let you know the outcome.

  • Contact the Gambling Commission

If you believe that an operator (perhaps one of the new UK online casinos) is in breach of their gambling licence, then you can report them to the Gambling Commission. However, it’s important to note that they do not resolve or make decisions on complaints regarding gambling-related transactions.
