Rules that apply in England

Questions from Stanley

What area around Stanley do you work in?

All of County Durham. Near Stanley that includes Annfield Plain, Chester-le-Street, Consett and Whickham.

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.
