MVHR installation in Hampshire

MVHR often makes sense in Hampshire homes that have recently been insulated, re-windowed or made more airtight.

Our team is based in Great Barr, Birmingham, and we work throughout Hampshire, from Basingstoke, Gosport, Waterlooville, Farnborough and Eastleigh. Surveys for new installations are free on the UK mainland, with a written quote afterwards.

What the work involves

Insulated ducts carry extract air from the wet rooms and supply air to the habitable rooms. Inside the unit the two airflows pass each other across a heat exchanger without mixing, so the incoming fresh air picks up heat from the outgoing air. Filters on both sides keep pollen and dust out of the house and keep the exchanger clean.

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.

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.

Questions about MVHR installation in Hampshire

Is the survey free in Hampshire?

For new installations on the UK mainland, yes. The survey is free and the quote that follows is fixed and in writing. Servicing, testing and repair visits are charged, and we confirm the cost before booking.

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.

Which rules apply to ventilation in Hampshire?

In England, ventilation in new and altered homes is covered by Approved Document F of the Building Regulations. Landlords also have duties under the Housing Health and Safety Rating System, and workplaces must be ventilated under the Workplace (Health, Safety and Welfare) Regulations 1992.
