Prior Approval

For development that is already permitted in principle, but where the council still gets a say on specific matters. Larger extensions and office-to-residential conversions are the common ones.

Authority

What makes it necessary

General Permitted Development Order 2015, Schedule 2. The council may only consider the matters the Class reserves. It is not an application for planning permission and the document does not argue as if it were.

Price

What it costs

This document is not priced on its own. It is part of the fixed fee for the application it supports, and a case producing three documents costs the same as a case producing one. On a householder application that fee is £499, with your council’s statutory fee passed on separately at cost.

A shorter research draft of this document is also available for credits, for your own use. It is clearly marked on every page as not for submission, and it carries nobody’s signature.

Questions

Questions

How is prior approval different from planning permission?

The principle is already settled by the Order. The council can only assess the specific matters that Class reserves, and it has a fixed period to do it in. It is a narrower question, which is why it is quicker.
