Plumb-Line has been endorsed by the Which? Trusted Trader scheme for over five years and we are recommended by 100% of clients who left a review on the Which? Website. We were awarded a Certificate of Distinction in April 2019 and we continue to score 4.9 out of 5 for customer service, quality and value.

The Which? Trusted Trader logo is a sign of reputation and trust, and the scheme is designed to help consumers find the right local tradesperson.

Which? Carries out a thorough assessment before a trader is allowed to join the scheme. This includes checks on the financial stability of the business, the level of customer satisfaction achieved and the business processes in place.

Having passed all the assessment checks, we commit to abide to abide by the Which? Trusted Trader terms and conditions and the Code of Conduct. We are then reassessed on a regular basis to ensure that we uphold the standards required.

All customer reviews are verified by Which? to be genuine and they are also subject to a rigorous moderation process.

Here is an example of a recent review left by a customer on the Which? Trusted Trader website:

“I ordered the boiler on the Wednesday. Installation date would be in a little over a week or so. Adrian had provided a quote a few days before and the customer service seemed very good, he was keen to ensure I understood everything and to provide what I wanted.

“The boiler broke down completely on the Sunday. Adrian came out on the Monday and tried to fix it but was unable to revive it. As I was without heating or hot water they managed to obtain the boiler I wanted overnight and it was installed on the following Wednesday.

“The two guys who installed it, Sam & George, were very pleasant and professional. Pretty good service by any standards. Thanks to all who made it possible.”
