What the work involves
PIV works well in houses and flats with general condensation on windows and cold walls. It does not replace extract fans: kitchens and bathrooms still need their own extract to remove steam at source.
Loft-mounted PIV
The most common option for houses with a loft. Usually fitted in half a day.
Heated PIV
A heater module tempers the incoming air in cold weather. Useful in homes where people feel draughts.

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.
