Ventilation for new builds, extensions and lofts in Shropshire

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.

Every job in Shropshire gets a written quote before it starts and a commissioning record when it finishes. We cover Loughton, Wellington, Oswestry, Ryton and Hadley and the villages around them.

What the work involves

Extensions and loft conversions have their own triggers: a new wet room needs extract, a new habitable room needs background ventilation or a connection to the ducted system, and energy-efficiency work can mean the existing home needs more ventilation too. 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.
