Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to paragraph 14 of the National Audit Office report on Sizewell C, HC 33, published in May 2026, whether his Department plans to analyse the potential impact of projected electricity bill increases during the construction of Sizewell C on households, commercial customers, and industrial customers.

The department estimates that RAB levies for Sizewell C will add on average approximately £1 a month to a typical household bill. Eligible Energy Intensive Industries are exempt from RAB levies.

There will be £2 billion per year savings to the energy system once Sizewell C is operational.
