Why join?

Which? Trusted Traders Approved Service logo

The Which? logo is regarded by consumers everywhere as a sign of reputation and trust.

You’ll be licensed to use the Approved Service logo when promoting the endorsed service on a range of channels, such as media advertising, company vehicles, direct marketing, your website and social media, invoices, in-store displays and more.

A dedicated account manager

We’ll work with you to make sure you always get the most out of the relationship.

Your dedicated account manager will help you to understand when and how to showcase the endorsement so it has the most impact on your customers.

In-depth business assessments

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

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.

Most people don’t care about boilers unless they need one and most people haven’t heard of us. When they ask “How can I trust you?” I immediately say “Because I’m a Which? Trusted Traders Approved Service”. That kickstarts the conversation.
