November 2013: All English local authorities were required to submit an updated Home Energy Conservation study report to DECC by 31 March 2013. An earlier post goes into these requirements in more detail and provides links to the report from those London boroughs who had posted them online on their website.
DECC have now published research summarising around 245 of these reports (see the Excel spreadsheet on the following link) as well as a document providing links to all reports published online. See both here. Only 20 London boroughs reports are however summarised on the spreadsheet. The HECA list states that some London boroughs have still not submitted reports: these appear to be Barking & Dagenham, Brent, Lambeth and Southwark.
It’s unclear if Bexley, Islington and Merton have submitted reports, as no links are listed – though the list does not say explicitly set out that these reports have not been provided: however, their actions are also not summarised on the spreadsheet.
