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 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.
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.
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.
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.
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:
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.
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.
| Third-party platform | Website | Email address |
|---|---|---|
| Gambling Commission | gamblingcommission.gov.uk | No, via online form |
| IBAS | ibas-uk.com | Yes |
Although you always have to give casinos a chance to resolve any complaints first, UK players are in the fortunate position of having an independent Alternative Dispute Resolution service available to them in the form of IBAS. This third-party platform is impartial, fair and easy to use and will ensure that all complaints are taken seriously. For more information, just click any of the links on this web page.
Before escalating any complaints, you have to give the casino in question eight weeks to respond.
Yes, you can.
Any company registered with IBAS agrees that their dispute decisions are binding, up to the value of £10,000.
The final step in the complaints process would be to take the casino in question to a small claims court.
Before using any online casino in the UK, you should check the footer of their website to ensure that they are licensed by the Gambling Commission.
Playing at online sportsbooks, real money casinos, and sweepstakes sites should always be safe and enjoyable. Keep control of your activity by following responsible gambling guidelines such as:
Decide on a budget you’re comfortable with and stick to it. Once it’s gone, stop playing.
Trying to recover losses often leads to overspending.
Avoid playing under the influence, or when angry, stressed, or tired.
Take breaks and ensure gambling doesn’t cut into time with family or friends.
Learn the rules, bet types, odds, and payouts before playing to avoid mistakes.
Make use of features like budget limits and self-exclusion.
