What happens next?

Horizon Nuclear Power has now submitted its application for Wylfa Newydd to the Planning Inspectorate. 

We always planned to make our application for consent after Horizon. This is so that the Planning Inspectorate can look at Horizon’s application first, before considering why our connection is needed as well as how it could be built.  

We’re continuing to have conversations with people and undertake assessments and surveys. This will make sure our application takes into account the latest possible information. 

  • Discussions with landowners – we’re talking to landowners and agents along the route. This includes giving new landowners an opportunity to comment on the proposals and continuing discussions about land use and access 
  • Meeting with local councils – we’re continuing to work with officers at Anglesey and Gwynedd Councils, to provide information on our proposals 
  • Summer work at the Menai Strait – our teams will be carrying out borehole surveys in the Menai Strait, which will help us understand more about the geology in the area

Our application to the Planning Inspectorate will contain lots of information, which will be published on its website. This will include detailed design drawings, an Environmental Statement explaining the potential effects of the work and our proposed mitigation measures. Details of the feedback we’ve received and how we’ve taken this into account will be in our Consultation Report. Our reports will also cover how we’ve considered Welsh language and the Well-being of Future Generations Act.

We will let people know when we submit the application and what happens next.

After the application has been submitted, the Planning Inspectorate manages the next stage of the process which takes around 16 to 18 months and will include public hearings. There will be the opportunity to get involved in these and provide your feedback directly to the Planning Inspectorate. 

If you’d like to know more, there’s lots of information on the Planning Inspectorate’s website (, including a useful video on how the process works and how you can get involved.
