What happens while it is decided

This application is with South Norfolk for determination, against a statutory target of eight weeks. Over the last year South Norfolk decided amendment applications in a median of 46 days. More in our guide to how long planning decisions take.

About amendment applications

An amendment application makes limited changes to a permission that already exists; anything beyond modest adjustment needs a fresh application. More in our guide to planning application types.
