The UK National Audit Office (NAO) estimates that building the Sizewell C nuclear power plant could add about £19 to household electricity bills. The NAO report comes as the Government moves forward with the project following a deal struck last year with investors to proceed with construction. Sources say the project’s total expected construction cost is around £38 billion. The NAO’s analysis focuses on the potential impact of those costs on consumer energy bills, tying the prospective household increase to the overall cost of delivering the plant. While the Government has committed to continuing the scheme, the NAO assessment highlights the scale of spending and the way it could translate into charges for electricity users. The coverage across outlets reflects the same core figures: an estimated £38 billion construction bill and an estimated £19 increase to electricity bills. The reports do not indicate changes to the project’s timeline in the provided excerpts, but they frame the NAO estimate as a potential cost to consumers arising from the project’s construction costs.
