Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, if he will make an estimate of the number of households that will require an electricity upgrade by the Distribution Network Operators to enable the electrification of heat and transport.

Government has not made such an estimate, which would depend on variables such as size of heat pump, power of electric vehicle charge point and existing supply capacity, where comprehensive data is not available. Domestic supplies can be upgraded if required, for example by installing a larger fuse, and the use of smart energy management solutions such as electric vehicle smart charging can also help reduce the maximum demand of a property to facilitate the installation, and use, of low carbon technologies.
