What MVHR installation involves

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. 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.

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.

New build or full renovation

Ducts go in at first fix before plasterboard, which is the cheapest and neatest time to fit MVHR.

Questions about MVHR installation in Essex

Are prices different in Essex?

Our guide prices are adjusted by region. In Essex we use East of England rates, so whole-home MVHR retrofit, 1 to 2 bedroom flat is typically £4,675 to £7,300 inc VAT per home.

Do I keep my trickle vents with MVHR?

No. Under Approved Document F, background ventilators should not be installed with a whole-home MVHR system, so we advise closing or removing them once the system is commissioned.

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.

Is the survey free in Essex?

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.

Which rules apply to ventilation in Essex?

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.

Every MVHR job in Essex finishes with a measured commissioning sheet, so you know the system does what it should.
