Open data

This page contains links to three different sources of data that could be useful for researchers, policy-makers and others working in the field of sustainable energy

1) Display Energy Certificate data
2) Lower Super Output Area data
3) Fuel poverty data (including 'hard-to-treat' data)

Display Energy Certificate data

CSE has obtained the full Display Energy Certificate Register dataset for all UK public buildings from the Department of Communities and Local Government, under the Environmental Information Regulations. [Read about how we did it here.]

It contains data on energy use, floorspace, emissions and efficiency ratings for 40,000 buildings of over 1,000m2 in England and Wales that are visited by the public.

The full dataset contains data from 2008 (the first year that the register was in force), 2009, and 2010.

We have also made a ‘latest data’ spreadsheet containing only the most recent energy performance data for any one address. However, around 146 addresses have more than one record for a given year, and without looking at the actual DECs it is impossible to say which of these is the most recent. For this reason the ‘latest data’ spreadsheet includes a supplementary table of  'duplicates' listing all the buildings for which this is the case.

Download the combined 2008, 2009 and 2010 data here (12MB)

Download the 'latest data' spreadsheet here (7MB)

Both files are in the newer Excel format (.xlsx). This keeps file sizes down. If you would like a .xls version, please email vicki.white@cse.org.uk

DECs for individual buildings can be downloaded from www.ndepcregister.com using the Certificate Reference Number (variable RRN in the datasets). The government's methodology for collecting the data can be found here.

Data health warning. Errors in the data collection or data entry can result in a building being given the wrong energy rating value. For example, we have found cases of buildings for which there is no kWh or CO2 data but which nonetheless have an A rating. This is beyond our control, and CSE cannot accept responsibility for errors in this data which was supplied by CLG.

The Lower Super Output Area dataset

The Community Energy Saving Programme (CESP) was designed to target  the lowest income households living in homes needing significant investment in energy saving measures and low carbon technologies. CSE mined the CESP data stores to develop and publish a database of useful information to assist with this targeting.

The dataset is available to download here (NB: this file is zipped).

Fuel poverty data

Useful data is also downloadable from CSE's three fuel poverty websites:

www.fuelpovertyindicator.org.uk
This site is designed to help target fuel poverty programmes and inform research. Includes downloadable maps and data.

www.energyefficiencywales.org.uk
A sister site to fuelpovertyindicator.org.uk (above) providing maps and data for Wales

www.ruralfuelpoverty.org.uk
The third of CSE's suite of fuel poverty indicator sites, this one focuses on rural fuel poverty particularly in relation to 'hard-to-treat' homes.

The full dataset used to produce this website can be downloaded here (NB this file is zipped).

Good data can be the key to successful policy-making and programme implementation
