Non-Material Amendment
A non-material amendment (NMA) allows you to make minor changes to an approved planning permission without submitting a new application. The change must be genuinely minor — not altering the nature or impact of the development in any material way. Examples include minor changes to window positions, small adjustments to dimensions, or updating a construction detail. More significant changes require a Section 73 application or a new planning application.

When to Use This Application Type
Use when you need to make a small, minor change to an approved permission that does not affect the principle, scale, or character of the development. If in doubt whether the change is truly non-material, contact your planning officer before applying.
