The Retrofit Map
Every local authority in England & Wales, coloured by its share of homes below EPC band C — the retrofit gap. Switch lenses to see matched-sale price per m², the rented-stock cut, and time-to-target. Click any area for its full report and citable figure.
At each area's current pace, the year almost all its homes are warm and cheap to run (the retrofit gap falls to 10%). An at-current-rate projection, not a forecast; areas not improving are shown as no-data.
Time-to-Target
cooler = reaches band C sooner · warmer = later
Boundaries: ONS Local Authority Districts (Open Government Licence). Figures modelled from EPC certificates and HM Land Registry Price Paid; price-based metrics are matched-sale estimates with partial match coverage, not valuations. Tap an area for its full report.
