I stuck it in the homeowning chat but might be more useful here - has anyone done a full insulation retrofit on a solid wall house? Anyone gone for EnerPHit? Currently have standard loft insulation, thinking about mostly external wall insulation and render (solid brick 1920s walls), small area of internal wall insulation, underfloor insulation and moving the thermal line out to the roof. Potentially replace windows (currently uPVC double-glazed so not bad but a bit old).
