What the work involves
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.

Questions from Royal Wootton Bassett
What is the price of a PIV unit in Royal Wootton Bassett?
Guide prices for Royal Wootton Bassett use South West rates: positive input ventilation (PIV) loft unit, supplied and fitted is typically £825 to £1,450 inc VAT per home. We confirm a fixed price in writing before any work starts.
How much does PIV cost to run?
A standard PIV unit uses very little electricity, comparable to a low-energy light bulb on normal speed. A heated unit costs more in cold spells because the heater switches on when loft air is cold.
Will PIV make my house cold?
Most units temper or reduce the flow when the incoming air is cold, and a heated unit warms it. Placed correctly on the landing, the air spreads gently rather than blowing on anyone.
