I'm looking at one to help with mould. It's in a 1950s brick semi and our North wall, where our staircase runs, is both external facing and unheated. It's supposed to have cavity wall insulation
Is it possible to heat that area instead? Electric radiator?

Not really.
It's a small staircase and the landing at the top isn't that big either, nor is there a plug. Plus it's the sort of thing that will be a hard sell to my OH.
Still it might be worth measuring up. Also there must be an electrical cable in the general area as the lights for our kitchen cupboards comes down from there. But I imagine an electric heater would need some sort of special circuit. So what's that:
- electrician = £500?
- slimline heater = £150-250?
- make good = £25?
Total = £700-800?
Vs
~£400 for a PIV....... maybe a lot more if we need a heated one and the heater uses enough to make me worried about adding it with a fused spur to the circuit in the loft.
- electrician = £500?

Does anyone have a PIV (Positive Input Ventilation) system installed?
I'm looking at one to help with mould. It's in a 1950s brick semi and our North wall, where our staircase runs, is both external facing and unheated. It's supposed to have cavity wall insulation, but I sometimes wonder how properly it was done. The double glazing we have looks fairly cheap and doesn't have those trickle vent things.
They don't look that expensive and seem straight forward to DIY fit - at least in our location.
