Insulation maps

Heatmaps

The “heat map”, as shown here for Cambridge roof insulation, gives a general overview of the condition of homes with an EPC in a particular street or postcode area .

The map shows red where there are lots of homes with very poor roof insulation, or uninsulated cavity walls. The orange, fading through green to blue indicates where homes merely have poor roof insulation or partially insulated cavity walls. Green and Blue indicates a lower density of homes.

Note that to preserve privacy, the heatmap does not locate individual homes, but just the location of the centre of the postcode area or street.
