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?”

"the vast majority of #SizewellC’s ££ comes from our taxes and energy bills so the reality is we are paying for [legacy] projects ourselves. Govt will learn well before Sizewell C is completed that there were better ways to spend our money”

We said: “Much is being made of the legacy aspects of #SizewellC, in areas the region is under provided for, especially education. But the vast majority of Sizewell C’s funding comes from the British public – from our taxes and the ‘nuclear tax’ on our energy bills – so the reality is we are paying for these projects ourselves.
It remains our view that the government will learn well before Sizewell C is completed that there were better ways to spend our money. Besides, how can we take Sizewell C’s promises seriously when they won’t even go public with a target completion date that is a little more specific than ‘mid to late 2030s’?’”

"The cost [of Westinghouse's reactors] of about $10 billion (£7.5 billion) per gigawatt of new capacity is significantly cheaper than the UK government’s recently approved plans for the #SizewellC plant in Suffolk. Sizewell is due to generate 3.2 gigawatts of electricity — enough to power six million homes — at a cost of £38 billion, or £11.9 billion per gigawatt.

The contrast will do nothing to alleviate concerns about the high costs of Britain’s nuclear programme, although the US plans are still at a much earlier stage. Critics have blamed factors including the UK’s choice of EDF’s “EPR” reactor and safety red tape for inflating nuclear construction costs in Britain. The costs of the 3.2GW Hinkley Point plant in Somerset, already under construction, are estimated to have risen to as much as £48 billion."

#SizewellC remains controversial. Local campaign groups are trying to block construction... as well as questioning the claimed economic benefits. Opponents argue consumers will be on the hook for delays and cost-overruns."
