Give your customers confidence

Which? Trusted Traders is an endorsement scheme that recognises trustworthy traders.

Which? has been helping consumers for over 60 years, and assesses and endorses traders who meet our high standards. Like the Best Buy logo, an endorsement from Which? Trusted Traders gives your customers confidence.

We operate all over the UK, and we endorse traders in the consumer home improvement, private motor servicing and repairs industries. Every business that applies is assessed by an experienced trading standards professional who makes sure they meet our high standards.

Which? Trusted Traders is completely free for all consumers, not just Which? members.

Find out why consumers value an endorsement from Which?

Which? exists to make consumers as powerful as the organisations they deal with.

We have 1.5 million members and supporters, making us the largest independent consumer body in the UK.

The Which? logo is regarded by consumers everywhere as a sign of reputation and trust. If your product or service has been awarded a Which? Best Buy or Recommended Provider, you know it's a mark of excellence that will help you stand out from the crowd.

Which? Trusted Traders was set up to ensure that the recommended trader market was delivering better value for consumers and traders.
