Document History

Last updated: 27 July 2026 - Relevant advice pages have been updated on an initial basis to reflect some of the key changes to the Planning Act 2008 process introduced by the Planning and Infrastructure Act 2025. These initial updates include the removal of all references to the obsolete statutory requirement for applicants to carry out pre-application consultation. A further detailed review of the Planning Inspectorate’s advice page collection will commence from summer 2026. This review will inform future updates to the advice page collection to fully align content with the amended legal framework.
