Non-Material Amendment
Changes something small on a permission you already hold, without going back for a new one. The test is whether the change is material, and that test is stricter than most people expect.

When
When your council will require it
- A minor change to an approved drawing
- A materials substitution
- A small dimensional correction discovered on site
Contents
What is in it
- 01The parent permission and its reference
- 02The amendment sought, precisely described, against the superseded and revised drawings
- 03Why the change is non-material: no material change to scale, appearance or planning impact
- 04Confirmation that no condition or planning obligation is affected
Authority
What makes it necessary
Section 96A of the Town and Country Planning Act 1990. There is no statutory definition of non-material, so this is judged by the council against the approved scheme.
Price
What it costs
This document is not priced on its own. It is part of the fixed fee for the application it supports, and a case producing three documents costs the same as a case producing one. On a householder application that fee is £499, with your council’s statutory fee passed on separately at cost.
A shorter research draft of this document is also available for credits, for your own use. It is clearly marked on every page as not for submission, and it carries nobody’s signature.
Questions
Questions
What if the council says my change is material?
You need a section 73 variation or a fresh application. The statement is written so the council can see the reasoning and tell you quickly, rather than sitting on an ambiguous submission.

Does your site need a non-material amendment?
Draw a boundary and the appraisal tells you which documents your route and your constraints require, before you commit to anything.
