i'm looking at MVHR (mechanical ventilation with heat recovery system) which we'll get professionally designed and do a mix of DIY and professional installation
want to get that sorted before doing any meaningful insulation

What's your logic? Avoid disruption to new finishes?
I'm looking at the other way around, fabric first. (Thinking it might be some time between them, and MVHR doesn't work in a leaky house from an energy/comfort point of view.)

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.
