Why joinShow you mean business
Which? Trusted Traders has teamed up with HETAS to help you get more recognition in the market. Customers already have peace of mind that you've got the technical skills to be accredited by HETAS. With our endorsement, they'll have the added assurance that your business procedures have also been vetted and you're committed to customer service.
Please note that Which? Trusted Traders are in partnership with HETAS and they do not hold an endorsement from Which?. All members of HETAS must apply and pass our assessment process before becoming a Which? Trusted Trader.

How much?
The cost depends on the size of your business, which includes employees and subcontractors. We have an initial one-off payment which goes towards the cost of your assessment - we cover the rest. It’s non-refundable, so if you don’t pass or you decide not to join, we can’t give you the money back. The endorsement fees can be paid monthly or annually.
Additional discount may be available if a member of a trade body - see list of partners here.

Mark Edwards, Managing Director, Timberwise Trusted Trader since 2016
The assessment process with Which? Trusted Traders was thorough and rigorous, ensuring that we met stringent criteria for competence, customer service and business practices. The assessment is not just a formality; it genuinely reflects the commitment of Which? Trusted Traders to promoting excellence and consumer confidence in our industry. The endorsement carries a weight that resonates with consumers, providing them with assurance and peace of mind when choosing a service or product. Taskforce Maintenance Ltd 28th Feb 24
Having the support from the Which? Trusted Trader Scheme helps promote us on a larger scale and gives people the security that we are part of a trusted scheme that promotes good quality workmanship, just like we do and we offer. The scheme offers continued support through an assigned rep that you can contact and also helps resolve disputes should they arise. This sets you apart from the rest - as its a scheme for life, not just for the moment.
Regal Kitchens 5th Feb 24
The assessment was harder than I thought it would be, but also eye-opening. I actually learned quite a bit through the process. The business has gone from strength to strength; I couldn’t imagine not having Which? behind us now. It sets you apart from the rest. People trust Which? and by us being in their scheme, it means they trust us from the get-go.

Common questions
What makes Which? Trusted Traders different?
Unlike other schemes, we do more than just check references and qualifications. Every business that applies is interviewed by an experienced trading standards professional to make sure that they meet our high standards. So, when customers see the Which? Trusted Traders logo, they know they’re using a trader that they can count on.
How long does it take to get endorsed?
We aim to get you endorsed within 30 days of applying to join the scheme. But this depends on how quickly you can send us the documents we need, and the dates you’re available for our assessor to visit you.
What is your Code of Conduct?
Our code of conduct sets out what we expect from the traders we endorse, and helps to protect consumers. All the traders on the scheme sign up to our code of conduct. You can read it here.
