How we approach MVHR in Barnet
MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. 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.
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.

Rules that apply in England

Questions from Barnet
What is the price of MVHR in Barnet?
Guide prices for Barnet use London rates: whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £5,350 to £8,350 inc VAT per home. We confirm a fixed price in writing before any work starts.
How often does MVHR need servicing?
Filters usually need changing every 6 to 12 months, and a full service with a clean and airflow check once a year keeps the system efficient. Clogged filters are the most common reason MVHR stops working properly.
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.
