Heating & boilers
Boiler installation, servicing & central heating
New boilers, annual services, radiators and complete central heating systems — installed and maintained by experienced heating engineers.
A well-installed, well-serviced boiler runs quietly in the background for years. A badly installed one costs you in fuel bills and call-outs. We treat every installation as one we'll be servicing for the next decade, because usually we are.
We install gas, LPG and oil boilers, and as Viessmann and Grant installers we can offer manufacturer's warranties of up to 10 years on qualifying installations. Before we quote we'll look at how your home actually uses heat and hot water so you end up with the right boiler, not just the biggest one.
Alongside installations we handle annual servicing, radiator and valve replacements, thermostats and heating controls, powerflushing, and full or partial replacement of central heating pipework.
