Securing Britain's low carbon future

The third stage of public consultation on the proposals for a new nuclear power station at Sizewell began on 4 January 2019 and will run until 29 March 2019. So far, our project has been through two formal stages of public consultation with local communities in East Suffolk, providing an opportunity for the public to have their say. The feedback we receive, together with our technical assessments, will help shape our final proposals.

During consultation we have sought opinions on:

  • Our overall proposals for the new Sizewell C nuclear power station;
  • The associated development needed to support the construction and operation of the power station; and
  • The potential effects of the project – both positive and negative – and proposed mitigation measures where necessary.

The principle of the need for new nuclear power stations and the choice of Sizewell as a ‘potentially suitable’ site have already been determined by Parliament, following public consultation and debate. These issues are outside the scope of our ongoing consultation.

Stage 3

Stage 3 consultation for Sizewell C will run for 12 weeks from 4 January to 29 March 2019 and will include 14 exhibitions across East Suffolk. The Sizewell C project team will be on hand to answer questions from local communities at the exhibitions. 

The proposals we're presenting have been shaped through feedback received from two previous stages of public consultation, on-going engagement with stakeholders, and substantial technical assessments and environmental studies.

Consultation has played an important role in informing and developing our plans and we would encourage you to play an active part in the Stage 3 consultation as some significant choices are presented and your feedback will inform our proposals.

Stages 1 and 2

Stage 1

At Stage 1 we consulted on our initial proposals and options for the construction of Sizewell C and associated developments, including an accommodation campus, transport by rail and sea, park and ride, and road improvements.

Overall 1,298 responses were received at Stage 1 Consultation, which ran from November 2012 to February 2013. The consultation included:

  • Direct engagement with over 4,000 local people;
  • Exhibitions, drop-in sessions and meetings with residents;
  • Presentations to parish and district councils;
  • Meetings with the New Anglia Local Enterprise Partnership, business organisations and chambers of commerce; and
  • Working with groups representing people with disabilities, older people, minority ethnic groups and young people.


Feedback from this first stage of consultation, along with technical workshops and information from further studies, modelling and assessments will help shape the plans published at Stage 2 Consultation.

Stage 2

Stage 2 Consultation on the proposals for a new nuclear power station at Sizewell began on 23 November 2016 and ran until 3 February 2017.

Our latest proposals have been informed by feedback from Stage 1 Consultation, ongoing engagement, further technical work and environmental studies.

Throughout November and December we hosted public exhibitions in a number of locations in East Suffolk, along with a number of presentations to schools, community groups and parish councils.

Stage 2 Consultation ended on Friday 3 February 2017. Thank you to those who submitted a formal response to Stage 2 Consultation on the Sizewell C proposals – we received over 1,000. All formal responses received are recorded and considered carefully by EDF Energy. The feedback will help us as we develop our plans for the next stage of public consultation on Sizewell C.
