Ventilation for new builds, extensions and lofts in Dunbartonshire
Ventilation designs, MVHR or extract installs and the commissioning paperwork building control needs, across Dunbartonshire.
- From £4,750 inc VAT per home
- Free survey
New homes, extensions and loft conversions need ventilation that meets the building regulations and is tested before sign-off. We design the system, install it at the right stage of the build, measure the airflows and provide the commissioning information building control asks for.
Dunbartonshire has every kind of building, from old terraces to new estates and business parks, and every job is designed around the building in front of us, not a standard kit.

How we do it
We work for self-builders, small developers, builders and architects. Fitting ducts at first fix is far cheaper than retrofitting, so it pays to involve us before the ceilings go up.
Commissioning only
Testing and paperwork for systems installed by others.
MVHR for new builds
Design, first fix, second fix and commissioning for whole-home heat recovery.
MEV or dMEV
Continuous extract systems where MVHR is not specified.
