Write to Andy Burnham and the NEW Energy Secretary, Miatta Fahnbulleh
We’ve a new Prime Minister and new Energy Secretary, Miatta Fahnbulleh, to write to about Sizewell C.
You can either send the text below, or write your own message
Dear Prime Minister
Dear Secretary of State
As part of your fresh start and drive to restore trust, I urge you to cancel Sizewell C. It is likely to become another government embarrassment like HS2, significantly overrunning its budget and schedule, with its technology largely unproven in the UK. You could free up billions of pounds of taxpayers’ money and cut household expenses by removing the “nuclear tax” from energy bills. You would also save the British people from expensive electricity in the future – even more than Hinkley Point C – and an uncertain supply with Sizewell C located on a vulnerable coastline. It is vital the UK continues the push towards net zero but there are cheaper and quicker energy solutions, especially responsibly delivered renewables that are a much better option for the UK.
Yours etc
(we recommend including your address)
If you want to write your own message, feel free to use any of the following suggested points, or those of your own choosing.
Cancelling Sizewell C would:
- Free up £ billions of taxpayers’ money (£14.2bn was committed to the end of this parliament but some has been spent), but we recognise money would have to be spent to restore East Suffolk.
- Reduce household expenses by removing the Regulated Asset Base (RAB, or “nuclear tax”) from energy bills.
- Save us from expensive electricity in future: the National Audit Office found Sizewell C’s electricity would cost £133 – £155/MWh [2024/25 prices], more than Hinkley C.
- Additionally Sizewell C can’t provide value for money as it is unlikely to operate at 90% load factor and there is a major risk of placing so much electricity supply on an eroding coastline. It will be another HS2.
- The EPR reactor is an unproven technology in the UK and has a catastrophic delivery track record elsewhere in the world.
- Call on Andy Burnham and Miatta Fahnbulleh to keep the UK progressing to net zero by prioritising cheaper renewable energy, responsibly delivered, and developing storage capacity.
- You can add any other points you wish, for example about nuclear waste, the danger of nuclear energy when there is conflict, and/or question whether Sizewell C is needed because of Sizewell B’s life extension. There are more points or ideas in our report “Sizewell C, The Unanswered Questions”.
