MVHR for Southsea homes
A single unit, usually in the loft, a utility cupboard or a garage, runs all the time at a low, quiet speed. Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms.
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.

Yes. We cover Southsea and nearby places including Portsmouth, Gosport, Cosham and South Hayling. Send your postcode and we will confirm.
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.
