  Erection of two storey front extension

  Decided 23 Apr 2026 Householder

This application is with Watford for determination, against a statutory target of eight weeks. Over the last year Watford decided amendment applications in a median of 32 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.
