   Barnet took a median of 46 days over the applications it decided in the last year.

This application is with Barnet for determination, against a statutory target of eight weeks. Over the last year Barnet decided amendment applications in a median of 42 days. More in our guide to how long planning decisions take.

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.
