This application is with Camden for determination, against a statutory target of eight weeks. Over the last year Camden decided prior approval applications in a median of 50 days. More in our guide to how long planning decisions take.

About prior approval applications

Prior approval applies where permitted development rights already grant the principle of the work, leaving the council only the specific matters the rules name, commonly within 56 days. More in our guide to planning application types.
