DECC publishes quarterly statistics of ECO and Green Deal (may it rest in peace). I have used the provisional cumulative figures of ECO installations provided in the September 2015 quarterly update (table 1.11a) to generate a GIS map. Click on the map to see six-monthly progress of ECO installations in a local authority.

The data reveal some interesting facts about ECO installations:

• Up to 30 June 2015 total 1,504,898 measures have been installed under ECO.

• Of this, only 5.1% (76,258) measures have been installed in Wales. At local authority level the smallest number of installations is 35 in Orkney Islands in Scotland.

• At county level North West of England (Blackburn with Darwen, Blackpool , Cheshire East, Cheshire West and Chester, Halton, Warrington, Cumbria, Greater Manchester, Lancashire and Merseyside) received highest number of installations which comprise of 18.7% (280,775) of total ECO measures. West Midlands (Herefordshire, Shropshire, Stoke-on-Trent, Telford and Wrekin, Staffordshire, and Warwickshire) received second highest number (12%, 180,211) of total ECO installations.

• At local authority level, Birmingham received highest installations, comprising 3.4% (50,738) of total ECO measures.

• 14% (203,989) of total ECO measures are installed in Birmingham, London, Glasgow and Cardiff (London data are cumulative of all inner and outer London local authorities). Factors such as easy accessibility to customers and high concentration of lead generators/ installers/ managing agents in urban areas may have played a major role behind such high installation rate in these four cities.

A similar analysis of CERT and CESP installations would be useful to understand whether the impact of energy efficiency scheme is largely limited to densely populated urban centres, and whether an area based approach should be adopted in future schemes.
