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.

Can MVHR cool the house in summer?
MVHR is not air conditioning, but a summer bypass lets cooler night air in without warming it, which helps take the edge off hot rooms. For real cooling you would need a separate system.
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.
