What the work involves
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.

Rules that apply 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 from Forest Hill
Is the survey free in Forest Hill?
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.
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.
