Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what survey data his Department (a) has commissioned and (b) holds since July 2024 on regional averages for when different areas turn on their heating systems in Great Britain.

The Department does not hold data on when different areas turn on their heating systems. Statistics on regional gas demand are published annually in Subnational gas consumption data. UK level monthly domestic gas demand is also published in Energy Trends table 4.2.
