— Our Process
How It Works
Survey & System Assessment
A Gas Safe engineer visits to check pipework, flue routing and the existing heating system to recommend a compliant replacement.
Preparation & Safe Removal
We isolate and drain the system, remove the old boiler safely and prepare pipework and mounting to industry standards before fitting the new unit.
Installation, Flushing & Commissioning
New boiler is installed, system flushed if required, controls set and the appliance commissioned. We register the boiler with the manufacturer to activate warranty cover.

Frequently Asked Questions
Install times vary by property and system complexity. A straightforward like-for-like swap in a standard house can be completed in a day, while full system upgrades or properties requiring new flues or alterations may take longer. We confirm timescales at the initial survey.
