How It Works

Safe removal & preparation
Drain and remove the old boiler and associated pipework, inspect and prepare tank, flue and combustion air arrangements to meet Building Regulations.
Install, commission & handover
Fit the new oil boiler and approved flue system, commission to manufacturer settings, run safety checks and leave full paperwork, user guidance and warranty details.

What we fit — Grant G1‑rated oil boilers, manufacturer‑approved flue kits and compatible controls chosen to suit your property and hot‑water demand. Rural properties around Churchdown, Newent and Stow on the Wold often need bespoke flue runs, external boiler houses or upgraded tank safety works; we plan for those constraints and specify the correct kit.
The full service — we remove your existing oil unit and responsibly dispose of it, check or replace tank fittings and vents, install the new boiler and flue, powerflush if required, and commission the system to manufacturer tolerances. All work is completed to Building Regulations standards and supported by manufacturer papers and our own post‑install checks.
