Spending watchdog warns £38bn cost of Sizewell C nuclear plant is ‘risky’

National Audit Office says potential benefits are ‘considerable but uncertain’ while risks are ‘immediate and substantial’

The cost of the government’s £38bn nuclear plant in Suffolk is subject to “significant uncertainty” and may outweigh the benefits for UK households until at least 2064, according to the government’s spending watchdog.

The National Audit Office (NAO) has warned that although the potential benefits of the Sizewell C nuclear plant are considerable, they remain uncertain. The risks, however, are “immediate, substantial and borne by the public”.
