Letter to complain about the poor standard of a service

Mae’r cyngor hwn yn berthnasol i Cymru

This letter applies to goods that you bought on or after 1 October 2015. 

If you bought the goods before 1 October 2015, contact the Consumer Service for advice on what to include in your letter. 

You might want to use it to complain about things like:

  • problems with car repairs

  • poor service in a hotel or restaurant

  • badly done hair and beauty treatments

It should help the trader understand your point of view and their legal obligation to sort out the problem.

If your problem is with poor quality building work, badly done decorating or a botched home improvement use the letter to complain to a trader about poor quality work instead.

You can send the letter by post or copy the text into an email. If you’d prefer to talk to the trader on the phone or in person you could read it out to them.

Before you use this template, make sure you read our advice on how to complain about a service or what to do if you have a problem with a car repair.
