Ventilation for new builds, extensions and lofts in Nottinghamshire

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 Nottinghamshire gets a written quote before it starts and a commissioning record when it finishes. We cover Hucknall, Nottingham, Mansfield, Worksop and Newark-on-Trent and the villages around them.

What ventilation for new builds, extensions and lofts 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.

MEV or dMEV

Continuous extract systems where MVHR is not specified.

Extensions and lofts

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

Commissioning only

Testing and paperwork for systems installed by others.
