How to complain about a casino

A licensed casino must have a complaints procedure and name an independent service to review disputes.

Key takeaways

  • Complain to the casino first.
  • Eight weeks, or a final response.
  • Then independent dispute resolution, free.
  • The regulator does not settle individual cases.

In brief: Complain in writing to the casino. If it is not resolved in eight weeks, take it to the casino's named dispute resolution service.

Step by step

  1. Gather evidence: screenshots, dates, chat transcripts.
  2. Use the casino's complaints form or email, in writing.
  3. Keep the reference number.
  4. Wait for a final response, or eight weeks.
  5. Refer it to the named dispute resolution service.

Dispute resolution

The service is independent and free to you. Its name is in the casino's terms.

The regulator

The Gambling Commission does not resolve individual disputes, but you can report an operator and it acts on patterns.

Unlicensed sites

None of this applies. That is the strongest reason to use licensed casinos.

What to write

  • Your username and the date.
  • What happened, in order.
  • What you want: the payment, the bonus, an explanation.
  • Your evidence, attached.

Keep it factual and short. A clear timeline is resolved faster than a long grievance.

How long it takes

Many complaints are settled within days. The eight-week limit is the point at which you may go elsewhere, not the usual wait.
