Nationally Significant Infrastructure Projects: updates to advice pages and other information
Summary
The Planning Inspectorate has updated its Nationally Significant Infrastructure Projects advice pages following legislative and guidance changes that took effect on 24 July 2026. The updates remove obsolete references, reflect new application and representation processes, and signal further revisions to come during August 2026 and beyond.
Why it matters
Although NSIPs are not routine residential matters, they can affect land use, access, and nearby development conditions that surveyors may encounter in valuation, due diligence, and planning-related work. Surveyors advising clients near major infrastructure schemes should note the revised process and the ongoing changes to consultation and application procedures.
Key points
- Planning Act 2008 process changes came into force on 24 July 2026 under the Planning and Infrastructure Act 2025.
- The Planning Inspectorate has updated several non-statutory NSIP advice pages to align with the new framework.
- References to the former statutory pre-application consultation requirement have been removed.
- New arrangements include submission of NSIP applications through the 'Apply for and manage your infrastructure project' site.
- Further updates to environmental advice pages and the pre-application prospectus are planned.
