I asked Chris to quote based on good reviews & was very pleased that he turned up on time, listened to what we were thinking of doing (a new boiler, extra radiators & possible tank removal or move) & then proposed a sensible package. Chris had lots of ideas which we were able to work through until we had a final plan. I had selected a new Viessmann boiler with weather compensation which turned out to be a totally new model & quite sophisticated. Chris worked out how to set up etc & also discovered that our 27 year old boiler was both plumbed & wired in such a way that it had never functioned correctly. Now all fitted & working we are very pleased with both the boiler & how it was fitted. Chris is very easy to work with, his work is very high quality, and everything was kept clean & tidy throughout. We will now use Chris for servicing & the new boiler even lets him know if it has a problem! Would highly recommend to anyone who wants a good job.

Start with one old cold, drafty house with a very old boiler, complicated pipe layout, an asbestos flue, needing 11 radiators, a new shower and with very picky owners. Introduce Chris who needed to think in 3D as he designed the new system which is completely different to the old system. The result? Lots of on-going problem solving, very uncomplaining about working in extreme heat or in a cold damp cellar, tidying up as he went along, keen to explain his working and his thinking, always with good cheer. He worked efficiently but did not rush tasks or cut corners. Very neat pipework and actually lots of it is cleverly concealed. Radiators all exactly level and some thoughtful features to ensure we enjoy an efficient system for years to come. Even though there were some challenges which took time to resolve (not his fault, just the awkward building) the end cost was within the original price. A pleasure to have Chris in our house doing this work, so based on his work, he is ...

Great service from Chris, friendly, knowledgeable and thorough in his work. Turned up when he said he would and nothing was too much trouble. Will not hesitate to use again in the future.
