Add stopping Sizewell C to Andy Burnham’s “to do” list

10 July 2026,

Paul Collins, Chair, Stop Sizewell C

Andy Burnham is on the cusp of succeeding Keir Starmer as Prime Minister, and one more nomination by a Labour MP will guarantee it. Help us add to his swelling in-box by asking him to reconsider Sizewell C!

We’ve drafted a very short sample email at the bottom of this email, but we strongly encourage you to write your own message as it will be more impactful. You could use some of the following suggestions:

It 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.
It would reduce household expenses by removing the Regulated Asset Base (RAB, or “nuclear tax”) from energy bills.
It would 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.
Sizewell C cannot provide value for money given it is unlikely to operate at 90% load factor and there is a major risk of placing so much electricity generation capacity 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 to keep the UK progressing to net zero by prioritising cheaper renewable energy, responsibly delivered, and developing storage capacity.

How to contact Andy:
Once you have written your message you can email it to: andy.burnham.mp@parliament.uk or copy it into the contact form on andyformayor.co.uk/contact or contact.no10.gov.uk. Or post a letter to House of Commons, London SW1A 0AA or 10 Downing Street, London SW1A 2AA.
