How we approach PIV in Market Deeping
Loft air is usually a little warmer and drier than outside air, and the unit filters it before it comes down into the house. Many units have a temperature sensor that reduces the flow or switches to a heater module on cold days, so the incoming air does not feel like a draught.
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.

Questions from Market Deeping
What is the price of a PIV unit in Market Deeping?
Guide prices for Market Deeping use East Midlands rates: positive input ventilation (PIV) loft unit, supplied and fitted is typically £775 to £1,375 inc VAT per home. We confirm a fixed price in writing before any work starts.
Does PIV really stop condensation?
PIV reduces condensation in most homes because it dilutes moist air and keeps it moving, but it works best alongside working extract fans in the kitchen and bathroom. Leaks, rising damp or a cold bridge need fixing separately.
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.
Is the survey free in Market Deeping?
