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.
Extensions and lofts
Extract for new bathrooms and kitchens, background ventilation for new rooms.
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.
