Mapping energy efficiency data at the parliamentary constituency level

Open data for England and Wales

17 April 2015

Over the last few months, the research team at CSE has been looking at the best way of producing data that shows the energy efficiency of housing in different areas of the country. The work has been fully funded by Citizens Advice; through it, we have looked at a number of options and their feasibility – a report will be available shortly.

One of the options considered (and the only one we'll discuss here) was the use of data contained in the National Energy Efficiency Data-framework administered by the Department for Energy and Climate Change. Our enquiries resulted in the release and publication of data showing the numbers of dwellings in each Energy Performance Certificated (EPC) band by Lower Super Output Area (LSOA) – an area that represents around 650 houses on average. This data is now available on the government website.

However, we have also used this data to calculate the numbers of dwellings in other types of areas including at Middle Layer Super Output Area (MLSOA) and parliamentary constituency areas. As a result, data showing the number and proportions of dwellings in each EPC band by LSOA, MLSOA and parliamentary constituency can be downloaded here.

In addition, we have also produced a series of maps of parliamentary constituencies.

High-resolution versions of the maps are available to download:

Percentage of homes EPC band C or above
Percentage of homes EPC band F or G

We’re making this data available as part of our Open Data Collaboration Initiative. See our Open Data page for more on this and access to our other datasets.
