Have Your Say

Pre-application consultation is essential in allowing KGSL to understand and respond to any questions or concerns. Extensive engagement and pre-application consultation was undertaken as part of the original DCO application and the Non-Material Change Application in 2022. 

We are holding a public consultation on the proposed Material Changes to the DCO consented in 2017 and on a range of updated environmental information. This will provide the project team with feedback from stakeholders and the community with a further opportunity to speak to the project team and submit feedback.

The public consultation period commences on Thursday 9 October 2025 and closes at 23.59 on Thursday 20 November 2025. There are several ways you can find out more and have your say:

  • Attend our Project Information Event at:
    De Vere Cranage Estate, Byley Lane,
    Holmes Chapel, CW4 8EW on
    Wednesday 15 October, 3pm – 7pm
  • Attend our online Question & Answers session taking place on Wednesday 22 October, 6.30pm (Register here)
  • Hard copies of the project documentation are also available for public inspection at the Storengy site at Storengy UK Stublach Site (Gatehouse), King Street, Northwich, Cheshire. CW9 7SE. Opening hours: Monday to Friday: 9:00am-4:00pm.

Next Steps

Following consultation, KGSL will prepare and submit a Consultation Report as part of the DCO application, which will include details of all feedback received and how KGSL has responded. The Material Change Amendment will be submitted to the Planning Inspectorate where there will be a further, 28-day period of consultation when comments can be made directly to the Planning Inspectorate.

A recommendation will then be made by the Planning Inspectorate. The ultimate decision will be made by the Secretary of State for the Department of Energy Security and Net Zero or DESNZ.
