Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the cost to households of environmental and social obligation policy costs included in (a) electricity and (b) gas bills in each of the last 10 years.

Policy costs on bills over the last 10 years have been published on Ofgem’s website: Ofgem’s Default Tariff Cap data (‘Final levelized cap rates model (Annex 9)’, tab: 1c Consumption adjusted levels, row 42). A key priority of the Government is to tackle Britain’s affordability crisis: the Government is acting to bring bills down now and over the long term through the transition to clean, home-grown power, and will continue to explore ways to both lower energy bills for consumers and reduce barriers for consumers to adopt clean technologies.
