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?”

Sir David King on how Britain is tilting into the sea on E because of erosion, amplifying effect of rising seas: “That’s the nature of the challenge we're all concerned about on the E coast - and around #SizewellC that clearly is a problem”

At least these #Leiston signs say WHERE road is closed & businesses are open but seriously @sizewellc do you really need to block whole carriageway? When lights are red & traffic waiting no one can pass. Guess @thebertonlion & @eelsfoot will lose customers anyway

.@thetimes nails it. "The rising cost — and a further delay to [#HinkleyC's] completion date — will be seen as a blow to the UK’s energy security and an indictment of its infrastructure record" and "It does not augur well for #SizewellC..."

#EDF today says #HinkleyC's operation delayed another year (or two) to 2030/2031 and costs increased from £31-34bn [2015£] to £35-36bn - that's £50bn in today's money. Oh and #SizewellC paid £1.6bn to #HPC for its "expertise" (yes really!)

“Of course, nuclear power plants aren’t always reliable and the most insecure power source is the one that isn’t built yet. Without the assumptions behind these cost guesses [of £120 per MWh], they are worthless and far from transparent.”
Alison Downes of #StopSizewellC said: “#HinkleyC’s cost has soared to £50bn with completion dates slipping and five years still to go. #SizewellC’s MWh costs [to consumers] will rise higher still when it inevitably overruns its £40bn construction budget.”
“That’s the nature of the challenge we are all concerned about on the east coast — and around Sizewell C, that clearly is a problem.”
