To make a complaint about a UK casino, start with the casino itself: use its complaints procedure, give dates, amounts and evidence, and keep copies. The business has 8 weeks to resolve your complaint; if you are still unhappy after that, you can take it to a free, independent Alternative Dispute Resolution (ADR) provider. UK casino complaints follow this route whenever the operator is licensed by the Gambling Commission.
This talk sets out each step, what to include and what to do if the casino is not licensed. It follows the Gambling Commission’s guide on how to complain. The brands on our UK casinos page all hold a Commission licence.
UK Casino Complaints: The Steps
- Check the casino’s terms and conditions for the rule in question.
- Find its complaints procedure on its website and complain directly.
- Give full details: dates, times, amounts and any evidence. Keep copies of everything.
- Wait for the casino’s response. It has 8 weeks to resolve the complaint.
- If you are still not satisfied, take the complaint to the ADR provider the casino names.
What Should You Include in a Complaint?
A complaint is easier to resolve when it is specific. Say what happened, when, which game or transaction was involved and how much money is concerned, and say what outcome you want: a refund, a corrected balance or a released withdrawal. Attach screenshots, emails and transaction references. The Commission advises keeping a copy of everything you send.
What Is an ADR Provider?
An ADR provider is a free, independent service that reviews unresolved disputes between you and a gambling business. You cannot go straight to ADR: you must first go through the casino’s own complaints process. The casino should tell you which ADR provider it uses and how to contact it, and it may give you a “deadlock letter” confirming that you can escalate.
Can the Gambling Commission Resolve My Complaint?
The Commission does not settle individual disputes between customers and casinos. What it does do is regulate how licensed operators handle complaints, and it wants to hear from you if you think a business is not following its own complaints policy or the rules of its licence. That information can feed into its compliance work.
What Are the Most Common Casino Complaints About?
Disputes often involve withdrawals held for identity checks, bonus terms applied in unexpected ways or account closures. On withdrawals, the Commission’s verification rules say a casino should not ask for ID as a condition of withdrawal if it could have asked earlier. On bonuses, the significant terms shown with the offer are the starting point, and UK wagering has been capped at ten times since 19 January 2026. Our glossary explains the terms casinos use.
What If the Casino Is Not Licensed?
Casinos that are not licensed by the Gambling Commission are not required to offer you dispute resolution, and you lose the protections of the British system. That is the strongest reason to check a site on the Commission’s public register before you deposit. If you are worried about a site you have already used, stop depositing and seek advice.
Frequently Asked Questions
According to the Gambling Commission, the gambling business has 8 weeks to resolve your complaint from when it receives it. When its investigation is complete, it should tell you the result and what happens next. If you are not satisfied after 8 weeks, you can take the complaint to an ADR provider.
Yes. An ADR provider is a free, independent service for disputes with gambling businesses. You must complete the casino’s own complaints process first, and the casino should tell you which ADR provider handles its disputes. The ADR’s decision process is separate from the casino and from the Gambling Commission.
The Commission cannot resolve individual disputes, but you can tell it if you are concerned about how a licensed business handles complaints or follows its licence. For your own dispute, go through the casino’s complaints procedure and then, if needed, the ADR provider it names.
Unlicensed casinos are not required to offer dispute resolution through the British system, so your options are limited. Check the Gambling Commission’s public register before using any site. If gambling with an unlicensed site is causing you problems, free and confidential help is available from the National Gambling Helpline.
The Bottom Line
A UK casino complaint has a clear path: the casino first, with full details and evidence, then ADR after 8 weeks if needed. Keep records from the start and only play at licensed sites, because the path only exists there. Our UK casino rules track covers the other protections a licence brings.
