About Flue Installation

We survey roof, wall and riser routes for length limits, bends, plume nuisance, terminal positions and fire-stopping needs, then install with the correct brackets, seals and weatherproofing. Replacement flues on existing boilers are planned to minimise heat-off time, and new boiler packages include flue design as standard. After install we run combustion analysis, check draught and CO where required, and leave clear user guidance. Stockport-based engineers cover Greater Manchester and surrounding counties.

Flue Installation FAQ

When does a flue need replacing?+

Common reasons include corrosion, damaged seals, incorrect original installation, boiler upgrade to a different flue type, or failed safety inspection. We confirm after a site survey.

Can you install flues through shared roofs or multi-storey risers?+

Yes where design and access allow. Shared or complex routes may need landlord approval, builders’ work openings and coordination with other trades — we flag this early.

Do you supply the flue materials?+

Typically yes: flue kits, extensions, terminals and accessories are included in the fixed quote unless you specify supply-only or client-supplied parts.
