Question to the Department for Transport:

To ask the Secretary of State for Transport, with reference to the Engineering Recommendation G100: Technical Requirements for Customers’ Export and Import Limitation Schemes, published in July 2016, what steps she is taking to encourage District Network Operators to accept new EV charging technologies.

The Government is committed to enabling innovative electric vehicle (EV) charging technologies, including smart charging and vehicle-to-grid (V2G), to reduce energy bills and support the decarbonisation of our energy system.

Engineering Recommendation G100 is the responsibility of the Distribution Network Operators (DNOs). It is regularly updated to facilitate connections, while ensuring they do not adversely impact on customers or the local electricity network.

As set out in the Clean Flexibility Roadmap published in July 2025, Ofgem and DESNZ are considering with industry how to improve grid connection processes and technical interoperability for V2G to ensure they are fit for purpose. This includes working with DNOs in relation to the grid codes which set out the technical requirements for connecting V2G systems.

More widely, Ofgem is working to improve the connections experience for all customers in its end to end review of connections.
