Nationally Significant Infrastructure Projects: Registering to speak at, or attend, a Nationally Significant Infrastructure Project event
Source: gov.uk (2025-04-01)

This advice is intended to explain how interested parties should register to participate in a Nationally Significant Infrastructure Project (NSIP) event.

The government has published guidance about national infrastructure planning which members of the public may also find helpful. See the National Infrastructure Planning Guidance (https://www.gov.uk/government/collections/national-infrastructure-planning-guidance) Portal. The guidance should be read alongside the Planning Act 2008 (https://www.legislation.gov.uk/ukpga/2008/29/contents) (the Planning Act).

This advice is non-statutory. However, the Planning Inspectorate’s advice about running the infrastructure planning system and matters of process is drawn from good practice and applicants and others should follow our recommendations. It is intended to complement the legislation, regulations and guidance issued by government and is produced under section 51 of the Planning Act.

How to register to speak at, or attend, a Nationally Significant Infrastructure Project event

The following are known as NSIP events:
- The preliminary meeting
- Open floor hearings
- Issue specific hearings
- Compulsory acquisition hearings
- Accompanied site inspections
The preliminary meeting and hearing events can be held online only or in a suitable venue with some people and organisations attending online and some in person, this is called a ‘blended event’.

Anyone can attend the preliminary meeting or a hearing in person at a venue but only interested parties have a right to request to speak. Only interested parties can request to attend an accompanied site inspection. See the Planning Inspectorate’s Advice for members of the public – Nationally Significant Infrastructure Projects and the people and organisations involved in the process for more information about interested parties. (https://www.gov.uk/government/collections/national-infrastructure-planning-advice-notes)

See the Planning Inspectorate’s Advice for members of the public – The stages of the Nationally Significant Infrastructure Project process and how you can have your say and What to expect at a Nationally Significant Infrastructure Project event for more information about events. (https://www.gov.uk/government/collections/national-infrastructure-planning-advice-notes)

You will need to complete a form to register to speak at the preliminary meeting or a hearing, or to attend an accompanied site inspection. You will also need to register if you wish to attend a blended event in person and not speak. You do not need to register if you just wish to watch an event online (see Watching the Preliminary Meeting or a hearing (#watch)). Everyone must register individually.

Important information about speaking at the preliminary meeting or a hearing

The preliminary meeting and all hearings are livestreamed which means that anyone can watch them as they happen by clicking on a hyperlink on the project information page of the Find a National Infrastructure Project website (https://national-infrastructure-consenting.planninginspectorate.gov.uk/). A video recording of the meeting and all hearings will also be published on the website.

Anyone speaking must introduce themselves each time they speak. If you are speaking at a venue you must use the microphones provided. Anyone who does speak needs to understand that what they say will be livestreamed and recorded.

Please speak to the case team if you do not wish to have your image recorded so that they can make arrangements for you to speak off camera, either online or at the venue.

The recordings of events are kept for 5 years in accordance with the UK General Data Protection Regulations (UK GDPR).

Anyone who speaks at the meeting or hearing must do their best not to give any information which should be kept private and confidential, such as health conditions or an address. See the Planning Inspectorate’s Advice for members of the public – Guidance for submitting representations or comments for further information about what should and should not be included in comments, either spoken or written.
