MVHR installation in Somerset

What the work involves

Filters on both sides keep pollen and dust out of the house and keep the exchanger clean. 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.

Radial semi-rigid ducting

One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.

Rules in England

In England, ventilation is covered by Part F of the Building Regulations and its guidance, Approved Document F (2021 edition). For homes, it sets minimum extract rates such as 15 litres a second for a bathroom and 30 or 60 for a kitchen, and expects mechanical systems to be airflow-tested.

Questions about MVHR installation in Somerset

Which towns in Somerset do you cover?

All of Somerset, including Bridgwater, Portishead, Frome, Burnham-on-Sea and Bath. If your town is not listed, send the postcode and we will confirm.

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.

Are prices different in Somerset?

Our guide prices are adjusted by region. In Somerset we use South West rates, so whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,625 to £7,250 inc VAT per home.
