   Awaiting decision

   Decision expected by 17 July 2026, 8 weeks from validation under the statutory target for most applications. Extensions of time are common and are agreed case by case.

   Hertsmere took a median of 57 days over the applications it decided in the last year.

This application is with Hertsmere for determination, against a statutory target of eight weeks. Over the last year Hertsmere decided householder applications in a median of 65 days. More in our guide to how long planning decisions take.

Householder applications cover work to an existing house and its garden, such as extensions, lofts and outbuildings, and cannot create a separate dwelling or change what the building is used for. More in our guide to planning application types.
