EDF says final costs could soar by about a third as it faces a delayed completion date.…this price shock comes at a sensitive time for the UK government, which has agreed to allow construction costs for a new plant at Sizewell in Suffolk to be added to customers' bills gradually over the decade which it will take to build.
The government has also just doubled its own investment into Sizewell C to £2.5bn and is in the process of raising capital from private investors.
Last week, the government triggered a "development consent order" that allows early-stage construction to begin in Suffolk despite several legal challenges from local and national opponents who have taken their fight to the Supreme Court.
