Recommend a trader now

We know it can be tricky to find a good trader. That’s why we launched Which? Trusted Traders.

Now it’s your chance to get involved. Tell us about a brilliant plumber, builder or mechanic you’ve used and would happily recommend.  

How does it work?

You recommend a trader. We vet them. If they make the grade, we endorse them so they become a Which? Trusted trader.

We’ll make it worth your while with a £40 John Lewis voucher for each trader that gets endorsed.

Three easy steps to recommend a trader:

  1. You recommend a trader by submitting this form
  2. We check them out (credit check, site visit, review of qualifications and references) and if they make the grade we endorse them
  3. You receive £40 John Lewis vouchers

Terms and Conditions

1.  The personal details for the trader that you recommend to Which? will only be used in conjunction with this referral offer. By providing us with the trader's contact details (including telephone number), you are confirming that you have obtained their consent for us to contact them. Please note, you will be stated as the person who has made the recommendation when we contact the trader by telephone and/or by email.

2.  To qualify for this offer, you need to complete the form or send a postal reply providing us with your name, the name of the trader you are recommending, their business name (if applicable) and their contact details (including telephone).

3.  Provided that the trader you recommend signs up to the Which? Trusted Traders scheme and becomes an endorsed Which? Trusted Trader, you will receive £40 worth of John Lewis vouchers. If you recommend a trader who is already undergoing the Which? Trusted Traders assessment process, you will not be eligible for the vouchers.  

4.  In the unlikely event that the John Lewis vouchers become unavailable, a suitable substitute of equal or greater value will be supplied. Cash alternatives are not available.

5.  Which? will aim to send the £40 John Lewis vouchers to you within 30 days of the trader paying their endorsement fee (or part thereof) to us.

6.  Which? reserves the right to refuse to send the John Lewis vouchers (or equivalent substitute) if we suspect that the terms of this offer are being abused.
