How we approach MVHR in Cranleigh
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.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Questions from Cranleigh
What area around Cranleigh do you work in?
All of Surrey. Near Cranleigh that includes Godalming, Guildford, Horsham and Dorking.
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.
