Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what estimate his Department has made of the number of households off of the mains gas grid in (a) each parliamentary constituency, (b) each council area and (b) the UK.

BEIS publishes the numbers of domestic properties not connected to the gas network down to Local Authority level. This includes properties where a gas grid connection is possible but no connection has been made. These estimates state that 4,128,000 (14 per cent) of domestic properties are not connected to the gas network in Great Britain. Equivalent data is available at Lower Layer Super Output Area (LSOA) and Middle Layer Super Output Area (MSOA) levels, but not by constituency or council area. For Northern Ireland, data on gas connections is available via the Annual Retail Energy Market Monitoring report.
