Central Heating- 5 Feb 2026
Dan came to the rescue when we had committed to laying our own underfloor heating and another plumber, who was going to connect it all, let us down. The quote was reasonable and he was great at replying to messages and flexible with our timelines, even when we had to complete the job in two halves, over three months apart. Very lucky to have found Dan and would call him again for any future jobs. Highly recommended!

First visit was by Craig who was polite and quickly diagnosed the problem. He had not seen this type of cistern flush valve, took photos and said he would try to obtain one. True to his word within a week he phoned saying he had located the new valve and would fit it a few days later. Called again later arranged a date and fitted in no time at all. very pleased would recommend this company. A.L.D

Pelham did a great home in replacing my faulty toilet cistern. He was professional in his job and interaction. What was also impressive is his willingness to go beyond 'his paid job' to provide advice, checks and help in resolving some electrical issues.
