Sizewell C ‘may cost double government estimates and take five years longer to build’

Research into costs of proposed Suffolk power station could further inflame debate over UK nuclear power

The proposed Sizewell C nuclear power station could cost UK taxpayers more than double government estimates and take an extra five years to build, according to research.

Ministers will decide in July whether to approve the development of the Suffolk power station proposed by the French developer EDF. The business department has estimated that the government-backed scheme will add an extra 1 a month to household bills to aid construction costs.
