    Vanishingly few houses are actually listed. Some are in conservation areas, which have similar but less strict restrictions on what changes you can make. These are the areas in my borough - almost half the built-up area, but i would guess proportionally less of the homes, because they are lower-density old buildings: https://www.haringey.gov.uk/sites/haringeygovuk/files/haringey_conservation_areas_map-2.pdf https://www.haringey.gov.uk/sites/haringeygovuk/files/haring... You can coax a London-wide map of conservation areas out of this, and see that most of the suburbs aren't covered by them: https://apps.london.gov.uk/planning/ https://apps.london.gov.uk/planning/ It probably is true that the most desirable houses are in those areas, but being in a conservation area helps preserve them and keep them desirable. Anyway, even within those conservation areas, there is plenty you can do to improve insulation. I had internal wall and ceiling insulation fitted, and replaced the window sashes with double-glazed ones.
