How we approach MVHR in St Ann's
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.
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.
New build or full renovation
Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Questions from St Ann's
How do I get a price for MVHR in St Ann's?
Use the guide price tool, the form on this page, live chat, WhatsApp or call 0800 088 6341. A postcode and a couple of photos help us give you a useful answer first time.
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.
