Sizewell C – Wrong Project, Wrong Time, Wrong Place.
Stop Sizewell C statement on Sizewell C’s Final Investment Decision, 22 July 2025.
“This much-delayed Final Investment Decision has only crawled over the line thanks to guarantees that the public purse, not private investors, will carry the can for the inevitable cost overruns. Even so, UK households will soon be hit with a new Sizewell C construction tax on their energy bills. It is astounding that it is only now, as contracts are being signed, that the government has confessed that Sizewell C’s cost has almost doubled to an eye watering £38 billion – a figure that will only go up. Given that Ministers claimed not to recognise the cost was close to £40 billion is there any wonder there is so little trust in this project?”

Can definitely see this happening here - indeed it already is with #SizewellC taking over Pontins Pakefield and plans for Darsham High Lodge...

"On average #nuclear projects worldwide end up with construction cost overruns of about 100% ... every new project will ultimately face the same test as every other technology: how fast can it deliver, at what cost, and at what risk?"

NB The NAO said a Final Investment Decision was made "4.5 years after negotiations started and at least 28 months later than originally planned. The project was delayed several times, including by the 2024 General Election; responding to feedback from potential investors and the government’s internal assurance processes; and longer than expected negotiations with EDF and the other investors."
