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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what recent estimate he has made of the costs of electricity and gas transmission and distribution networks to consumers.

Data from the independent Great Britain energy regulator, Ofgem, show that the average estimated network costs per domestic customer per year in March 2021 were: gas distribution - £121; electricity distribution - £93; electricity transmission - £35; gas transmission - £10. This data is published at https://www.ofgem.gov.uk/energy-data-and-research/data-portal/all-available-charts?sort=created&page=2 (chart: ‘estimated network costs per domestic customer’).
