Planning Appeals Reform from April 2026: What Applicants Need to Know

The Government has published a new Planning Appeals Procedural Guide for appeals relating to planning applications received on or after 1 April 2026, marking a significant shift in how most appeals will be handled in England.

The updated framework sits alongside recent amendments to the appeals regulations and reflects a broader drive to streamline the Planning Inspectorate’s processes and accelerate decision-making. While the existing procedural guide continues to apply to applications submitted on or before 31 March 2026, the new regime introduces several important changes.

The Main Changes

Default to an expanded written representations procedure: Most section 78 appeals (refusals of planning permission and condition appeals) will now be determined through an expedited written representations process. This approach, previously limited to householder and certain minor cases, is being rolled out more widely.

No new evidence at appeal stage: Under the expanded procedure, appeals will generally be decided on the basis of the material submitted at application stage. There is no opportunity to introduce new evidence once the appeal has been lodged, reinforcing the importance of submitting a robust and complete planning application from the outset.

Faster, more streamlined determinations: The revised process is designed to reduce delays and administrative burden, supporting quicker decisions and improving overall system efficiency.

Digital submission requirements: Appeals must be submitted via the Planning Inspectorate’s updated digital service, replacing older portal systems and standardising case management nationally.

For applicants and planning professionals, the message is clear: front-load evidence, anticipate policy arguments early, and treat the application stage as the critical point of assessment.
