Nationally Significant Infrastructure Projects : Advice on working with public bodies in the infrastructure planning process

The government has published guidance about national infrastructure planning which applicants, members of the public and other parties should read. See the National Infrastructure Planning Guidance Portal. The guidance should be read alongside the Planning Act 2008 . 

This advice page is produced by the Planning Inspectorate. It is non-statutory. However, the Planning Inspectorate’s advice about running the infrastructure planning system and matters of process is drawn from experience and good practice.practice Applicantsand applicants and others areshould encouraged to follow our recommendations. OurIt advice is intended to complement the legislationlegislation, regulations and guidance issued by government.government. 

What is a public body?   

A public body is a formally established organisation that is publicly funded to deliver a public or government service. The Planning Inspectorate has provided separate separate Advice for Local Authorities which which includes information about the role of local authorities in the NSIP process. 

Public bodies in the NSIP process:  

• have a role as statutory bodiesconsultees  
• may have parallel consenting powers to grant consents (other than development consent), or other authorisations that may be required for the construction, use or operation of a NSIPNSIP 

They have an important role providing expert advice on a proposed NSIP throughout the process, from early pre-application engagement, the provision of examination evidence and in relation to post consent activities. Public bodies can help the applicant with the early identification and mitigation of impacts associated with NSIPs.  

There are separate annexes to this advice which provide more detail about the specific roles of individual public bodies in the NSIP process and their interaction with the Planning Inspectorate:

Annex A: Cyfoeth Naturiol Cymru / Natural Resources Wales

Annex B: Marine Management Organisation 

Annex C: Natural England 

Annex D: Environment Agency 

Annex E: Historic England 

Annex F: Nuclear Regulators

Annex G: The Health and Safety Executive 

Annex H: Evidence Plans for Habitats Regulations Assessments  

The annexes include information about: 

• the specific role of the relevant public body and the interactions with the role of the Planning InspectorateInspectorate 
• specific high-level agreements and arrangementsarrangements 
• relevant contact pointspoints 
• a list of relevant consents or other authorisations that apply, and considerations relating to how those interact with the NSIP processprocess  

Further information about consulting with these public bodies is provided in the Planning Inspectorate’s Inspectorate’s Pre-applicationAdvice advice on Environmental Impact Assessment (EIA).Notification and Consultation. 

 Public bodies and the NSIP process   

There are 6 stages to the NSIP process. Further information about each stage of the process is provided in Planning Inspectorate’s Inspectorate’s Advice for members of the public – The stages of the NSIP process and how you can have your say.  

Following an operational review of the NSIP system the government published a reform Action Plan. The government then consulted on the operational changes proposed in the Action Plan and published a response to the consultation in March 2024. To support the reforms legislation has been amended and the government has published new and updated guidance. The Planning Inspectorate has developed a new pre-application service to support the government’s reforms. See the Planning Inspectorate’s Pre-application Prospectus for further information.  

Amongst other matters the adopted reforms will enable the following public bodies are able to charge applicants for the planning services they provide for NSIPs:

• Natural EnglandEngland 
• Natural Resources WalesWales 
• MiningThe RemediationCoal AuthorityAuthority 
• The Health and Safety ExecutiveExecutive

The government’s PlanningGuidance Acton 2008:the updated Infrastructure Planning (Fees) Regulations 2010 - cost recovery by The Planning Inspectorate and Public Bodies  provides further information about cost recovery for these public bodies and the Planning Inspectorate. 

Summary of how public bodies may be involved at each stage of the NSIP process  

The applicant is responsible for accessing the resources of the relevant public bodies and ensuring that they obtain the services they require for producing a well prepared NSIP application. Some of the involvement in this summary will be subject to cost recovery by the relevant public bodies.

Pre-application 

Pre-application engagement and/and or consultation is fundamental to the NSIP process. WhilstThe it is not a statutory requirement, the applicant is stronglyrequired encouraged to consult a wide range of people and organisations at the pre-application stage, including the public bodies featured in the annexes to this advice. 

The applicant should request any necessary technical information from public bodies at an early stage. This will allow them to consider mitigation for negative effects and potential opportunities to secure environmental enhancements when preparing their application.  

The applicant may ask public bodies for advice on matters under under The Conservation of Habitats and Species Regulations 2010 and/ or the Marine and Coastal Access Act 2009 and / or or The Water Environment (Water Framework Directive) (England and Wales) Regulations 2017. The Planning Inspectorate has published separate advice on these subjects. See the Planning Inspectorate’s Inspectorate’s Advice on Habitats Regulations Assessment and  and Advice on the Water Framework Directive.  

Environmental issues arising from the EIA,Environmental HRA,Impact MarineAssessment Conservation(EIA), ZoneHabitats (MCZ)Regulations Assessment and(HRA), Flood Risk Assessment (FRA) and so on may be recorded by the applicant in an ‘evidence plan’.  

Public bodies should respond to the applicant’s requests for advice as promptly and comprehensively as possible, taking into account their own service offering and the agreed programme document (see the Planning Inspectorate’s Inspectorate’s Pre-application Prospectus).   

Full and meaningful engagementconsultation and/and orengagement, consultation, before the submission of an application, should result in a smoother pre-application experience for all stakeholders, lead to a well-prepared application including necessary and relevant detailed information and reduce the risk of changes to the application being proposed at too late a stage in the NSIP process (see paragraph 4.23018 of the government’s government’s Guidance on the examination stage offor anNationally applicationSignificant Infrastructure Projects). 

At the pre-applicationPre-application stage, where possible, the Planning Inspectorate encourages public bodies (and other stakeholdersconsultees as necessary) with related areas of responsibility to work jointly and co-ordinate responses both to the applicant and the Planning Inspectorate.  

Public bodies can refer to the Planning Inspectorate’s Inspectorate’s Advice forto Local Authorities for for information about how they should engage with the applicant and the Planning Inspectorate on the following: 

• a PADSSPrincipal Areas of Disagreement Summary Statement (PADSS)

Environmental Impact Assessment (EIA) Scoping Opinion 

The applicant may ask the Planning Inspectorate (who will act on behalf of the Secretary of State) for a formal written opinion about the information they should include in their environmental statement. This is known as a scoping opinion. 

The applicant will send a scoping report to the Planning Inspectorate (known as the scoping request) who will publish it on the project information page of the the Find a National Infrastructure Project website. The Planning Inspectorate must adopt a scoping opinion within 42 days of receiving the scoping request. The Planning Inspectorate will consult the relevant public bodies as identified consultees on the scoping report (for further detail on consultation and notification please see the Planning Inspectorate’s Inspectorate’s Advice on Environmental Impact Assessment Notification and Consultation). They will invite them to respond within 28 days to allow the Planning Inspectorate time to consider the responses before the deadline for adopting the scoping opinion. If a public body does not respond to an EIA scoping consultation request within the defined statutory deadline, the Planning Inspectorate will assume that they do not have comments to make on the information to be provided in the applicant’s environmental statement. 

The applicant should avoid combining anyconsultation pre-applicationrequired consultationby itsection decides42 toof undertakethe Planning Act 2008 with a request for an EIA scoping opinion. This is because it will result in more than one form of consultation taking place at the same time leading to confusion. This may ultimately frustrate the NSIP process. 

The applicant’s preparation of their environmental statement   

If the proposed NSIP is EIA development the applicant must include an environmental statement when they submit their application.  

Regulation 11 of The Infrastructure Planning (Environmental Impact Assessment) Regulations 2017 describes describes the process which EIA consultation bodies, including public bodies, must follow to engage with the applicant when they are preparing their environmental statement. Further detail is provided in the Planning Inspectorate’s Inspectorate’s Advice on Environmental Impact Assessment Notification and Consultation.  

The applicant is responsible for ensuring their environmental statement is adequate. If, during the acceptance stage the environmental statement is not deemed to be compliant with with Regulation 14 of The Infrastructure Planning (Environmental Impact Assessment) Regulations 2017, the application will not be accepted. If it comes to light during the examination stage that the environmental statement is inadequate consideration of the application could be suspended pending receipt of further information (see (see Regulation 20 of The Infrastructure Planning (Environmental Impact Assessment) Regulations 2017). It is therefore important that public bodies and the applicant work together at the pre-application stage to reduce these risks. The applicant should also ensure that all the relevant consents which are required to enable construction and operation of their NSIP are set out in the environmental statement. Public bodies should assist the applicant in meeting these obligations when requested. 

Consents and authorisations  

Some public bodies may have powers to grant consents (other than development consent) or other authorisations that may be required for the construction, use or operation of a NSIP.  

Certain consents or authorisations can be included in the DCO,Development Consent Order (DCO), or they can be consented separately. separately. Section 150 of the Planning Act 2008 confirms confirms that these consents can only be included in a DCO if the relevant consenting body agrees to their inclusion.  

The applicant iswill encouragedneed to engage with public bodies, and any other relevant stakeholdersconsultees that have consenting powers, early in the pre-application stage. The applicant’s programme document should include details about the timing of applications for separate consents or authorisations, and/and / or engagement with the relevant bodies to obtain agreement for inclusion of consents or authorisations in the DCO. 

Where consents or authorisations are to be included in a DCO, the applicant should time their engagements with the relevant bodies to enable agreement on matters as much as possible at the pre-application stage.   

Where the applicant has decided to apply for consent or authorisation separately they should provide a ‘schedule of consents’ with their application setting out: 

• all consents and authorisations required alongside the DCODCO 
• which body is responsible for granting consent or providing authorisationauthorisation 
• the proposed timeline for applying for the consents and authorisations and how that aligns with the NSIP process.process.  
• up-to-date details of the status of progress on each consent or authorisation applicationapplication 

The timing of decisions on these consents and authorisations may have an important impact on the examination of the application and should be considered carefully. Government policy on this point, as set out in the National Policy Statements, will be an important consideration in this respect.  

Public bodies and other stakeholdersconsultees should assist the applicant in compiling a comprehensive and accurate schedule. Greater detail on the interaction between the Planning Act 2008 and specific, relevant consents and authorisations required under other legislation are set out in the annexes to this advice as they apply to individual public bodies. Specific considerations are also likely to apply in individual cases. 

Deemed consents  

The applicant may choose to apply to the MMOMarine Management Organisation (MMO) for a Marine Licence, or they may choose to have the Marine Licence deemed by the DCO made by the Secretary of State - a Deemed Marine Licence (DML). The inclusion of a DML in a DCO does not require the approval of the relevant consenting body (unlike section 150 consents).  

The applicant will need to decide at the pre-application stage whether they will apply separately for such consent or have it deemed by a DCO. TheTheir decision should be reflected in thetheir programme document as appropriate. 

Harbours  

The applicant will decide if their NSIP application should include: 

• provisions for creating a harbour authorityauthority 
• provisions for changing the powers or duties of a harbour authorityauthority 

A DCO may also make other provisions in relation to a harbour authority. 

The MMO may also separately deal with Harbour Order applications unless the development of the harbour itself is a NSIP or an integral part of a NSIP. See See section 33(2) of the Planning Act 2008 for for further information.  Although it is for the applicant to decide which route is the most appropriate for their NSIP, it should be noted that there is no Secretary of State / MMO dual jurisdiction in relation to the same set of works (see (see section 120(9)(a) of the Planning Act 2008).
