What the work involves
In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit. We check this on survey and tell you plainly if a simpler system would do the job for less.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.
Retrofit in an occupied home
Ducts routed through the loft and down through cupboards or boxed corners. Most semis are done in 3 to 5 days.

English building work follows Approved Document F (2021 edition) for ventilation rates, installation and commissioning. It sets extract rates for kitchens, bathrooms and utilities and asks for mechanical ventilation to be commissioned and recorded.
Questions from Harlesden
Do you cover Harlesden and nearby?
Yes. We cover Harlesden and nearby places including Willesden, Kensal Green, Queen's Park and Cricklewood. Send your postcode and we will confirm.
How much does MVHR cost to install?
A typical retrofit costs £6,450 to £9,450 including VAT for a three-bedroom house, and £4,950 to £7,950 when it goes in during a new build or full renovation. Flats start lower and large detached homes cost more because of the duct runs. We give a fixed price after the survey.
Is MVHR worth it in an older house?
It can be, but the payback is best in a home that is fairly airtight. In a draughty house MVHR still gives steady fresh air and condensation control, but a PIV unit or continuous extract fans may solve the same problem for far less. We will tell you which on survey.
