Excellent service.
Customer Service
Fitted new central heating, boiler and radiator. Very helpful when doing the work, clean and tidy. Very professional work done on time and to original quote. After-care was excellent and sorted out other problems I had. Would highly recommend to anyone.

Always happy

Had my heating system replaced by Darren and subsequently use him to service it annually. Always does a great job and I would be happy to recommend him to others.

Spot on
Customer Service
Had my boiler repaired 4 months ago by Darran, who came recommended to me. He did a fantastic job and did so quickly and efficiently, as well as being friendly. Spot on job - would definitely recommend to others.

A truly professional organisation
Customer Service
We had Underfloor Heating fitted very poorly by another installer. It never worked satisfactorily. Darren Grant was willing to use his expertise to diagnose the problems and retro fit a new control system. The heating system now works well for the first time since it was installed. It was a pleasure to be Darren's client. We received full information. We were given clear options and the new installation was done very professionally.

First class service
Customer Service
New boiler and water tank fitted, plus new piping fitted to an old system that wasn't working. Darran and his team carried out the work as promised and at a high standard - thoroughly recommend!
