Big Changes to Planning Appeals from April 2026 — What You Need to Know

Faster — But Less Flexible

From 1st April, most appeals will go through a streamlined “Part 1” written representations process, meaning decisions should be issued more quickly.

But, you won’t be able to submit any new evidence at appeal stage. This even seems to include a signed S106 (where required).  "Submit once, submit right" at application stage is the strong message. 

What This Means for You?

These reforms will make early preparation and front loading more important than ever. Since the appeal will likely rely entirely on your original submission, the planning application needs to be:

-Thorough

-Well‑evidenced

-Strategically thought‑through

-Resilient enough to stand without later additions
