Home ventilation, Scottish Islands
Positive input ventilation (PIV) in the Scottish Islands
Loft or wall units that gently push filtered air into the home to tackle condensation, across the Scottish Islands.
- From £775 inc VAT per home
- By arrangement
PIV can suit Scottish Islands houses and flats because it treats the whole home from one quiet unit.
Across the Scottish Islands the job is priced the same way wherever you are: what is fitted, how long it takes and how far we travel. Towns we cover include Stornoway.

How we do it
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. On survey we check the loft, the landing position and the existing fans, and we tell you if PIV is not the right answer.
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.
Wall-mounted PIV for flats
Draws air from outside through an outside wall. Suits flats and homes with no loft space.
