Ventilation for new builds, extensions and lofts in Tyne and Wear

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.

Our team is based in Great Barr, Birmingham, and we work throughout Tyne and Wear, from Wallsend, Newburn, Newcastle upon Tyne, Sunderland and South Shields. We survey first, free of charge for new installations on the mainland, then send a fixed written quote.

How we do it

For new dwellings in England, Approved Document F sets whole-home ventilation rates and requires mechanical systems to be commissioned and the results given to building control. 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.

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.
