This application is with Powys for determination, against a statutory target of eight weeks. Over the last year Powys decided lawful development applications in a median of 71 days. More in our guide to how long planning decisions take.

A lawful development certificate is a legal determination that existing or proposed works do not need planning permission; the merits of the scheme are not considered. More in our guide to planning application types.
