Frequently asked questions
What is MVHR?
MVHR (Mechanical Ventilation with Heat Recovery) is a whole-home ventilation system that extracts stale air from wet rooms, supplies fresh filtered air to living areas and bedrooms, and transfers heat between the two airstreams through a heat exchanger.
How do I know if I have MVHR?
Look for a white or grey box in a loft, utility cupboard or ceiling void with two sets of ducts, and valves in the ceilings of kitchens, bathrooms and bedrooms. It usually has a fused spur and a controller or boost switch. Your building's O&M manual or EPC may also state it.
How often should MVHR be serviced?
Once a year, with filters checked every 3–6 months and replaced every 6–12 months.
How much does an MVHR service cost in London?
With MVHR Expert it is £140 for a 1-bed, £160 for a 2-bed and £200 for a 3-bed, including filters, heat exchanger clean and an airflow check. Larger homes and multiple units are to be discussed.
How much does MVHR repair cost?
A £140 call-out covers attendance and full diagnosis. We quote any repair before starting work.
Do you cover all of London?
