How It Works

A Gas Safe engineer inspects your existing system, checks flue options and pipe runs, then recommends suitable boiler models and any required system upgrades.

Benefits

Why Choose us for Boiler Replacement?

Gas Safe registered engineers

All gas work is completed by Gas Safe qualified operatives, giving homeowners and landlords the safety assurance and compliance documentation they need.

Domestic heating specialists

Focused on homes in Dumbarton and nearby towns, the team configures replacements for tenements, semi-detached and modern builds to maximise performance.

End-to-end service

We handle flues, pipework, controls and commissioning so you get a fully tested, certified system without juggling multiple contractors.

Boiler replacement is more than swapping the box. We select appropriate condensing combi, system or regular boilers from established manufacturers and fit the correct flue kits, pressure relief arrangements and sealed-system components for your property type. Pipework alterations, condensate routing and termination positions are handled to current regs, with manufacturer registration and warranty advice provided at handover.

All installations are carried out by Gas Safe registered engineers and finished with full commissioning checks — gas tightness, operational safety tests and a completion certificate. Landlords can request a CP12 gas safety check after installation if required, and we recommend a power flush where internal sludge or system contamination could reduce new-boiler performance.
