Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps she is taking to help support the (a) development and (b) adoption of vehicle to grid technology.

The Government is committed to supporting the rapid development and adoption of Vehicle-to-Grid (V2G) technology as it has the potential to reduce the cost of electric vehicle (EV) ownership while supporting the decarbonisation of our energy system.

Whilst the technology is still nascent, it is quickly commercialising. The Government is currently providing industry with over £10m innovation funding support through its V2X Innovation Programme (2022-2025). This is in addition to the funding support of over £28m previously provided through its Vehicle-to-Grid innovation programme (2018-2022).

The Government and Ofgem outlined collective ambitions and further actions relating to Vehicle-to-Grid technology in the Clean Flexibility Roadmap published in July 2025. These include removing financial barriers, such as the double charging of levies on re-exported electricity, as well as improving grid connection processes and enabling technical interoperability for V2X.
