The cost of building the Sizewell C nuclear power plant in Suffolk has doubled since the plans were presented to the UK government in 2020 and could now reach close to £40bn, according to reports.

A rise in construction charges over recent years, combined with cost overruns and delays at EDF’s Hinkley Point C nuclear project in Somerset is expected to increase the final bill to build a successor project at Sizewell, according to the Financial Times.
