Updated quarterly. This layer works well on a projection-matched greycale basemap such as m0130. An OpenLayers-based overlay demo is available.
As colour is used in this layer to signify EPC efficiency function, no greyscale version is provided.
This layer uses standardised colours for energey efficiency ratings.
