Your service will get a comprehensive health check from our highly experienced trading standards assessors.

You’ll be assessed before you join and on every anniversary. Plus we’ll talk you through any recommended improvements.


Help resolving complaints

Two opposing chess pieces

Even the best business occasionally gets complaints. If your service runs into a dispute with a customer that you can’t resolve, we can help.

We offer access to our independent Alternative Dispute Resolution (ADR) service, provided you meet the criteria and are not already a member of such a scheme.
