Sizewell- £38 Billion
Posted: 19th July 2025
Ministers set to admit Sizewell C nuclear plant price-tag has soared to £38bn. New official estimate reflects surging construction inflation and contingency costs. Sizewell C nuclear plant will cost £38bn to build, the UK government is set to admit for the first time next week as it reveals the terms of an expected deal for private investors to fund a small portion of the bill. The new official estimate is a big increase from a £20bn figure given by French energy giant EDF and the UK government for the project in 2020, reflecting surging construction inflation and new contingency costs. A trio of private companies are set to invest around £9bn of equity in Sizewell, but the majority of the construction will be funded by loans underpinned by a levy on consumer bills, according to people familiar with the matter. The UK government is expected to remain the largest investor in the project with a 47.5 per cent stake, the Financial Times previously reported. The £38bn cost, details of the deal and how the financial risk of the project will be shared is set to be announced before the parliamentary summer recess begins on Wednesday, the people said.
