Some types of development do not need planning permission. This is called 'permitted development'. The rules can change so you should check what the latest position is before you begin to build. A range of interactive guides are available covering some of the common building projects together with the guide to permitted development for householders (PDF 269KB).
If you want to be certain that your proposal does or does not require planning permission we currently offer a permitted development enquiry service for which there is a fee of £50. Please complete the Permitted Development Enquiry Form (PDF 1.3MB) and pay your fee. We will check this and send you a letter within 10 working days telling you whether you need permission or not.
However, from 1 April 2017, the permitted development enquiry service will no longer be provided. Instead if you want the certainty that the existing use of a building is lawful for planning purposes or that your proposal does not require planning permission, you can apply for a 'Lawful Development Certificate’. You can apply for this certificate and get more information on Lawful Development Certificates on the Planning Portal. Use the Planning Portal also for Applications for a Certificate of Lawfulness of Proposed Works to a listed building (PDF 281KB).
You may still need Building Regulations consent, please check the Related Pages section for further information.
A form is available to apply for a larger single storey rear extension (PDF 232KB) with a guidance note (PDF 59KB) to complete the form. Information on the Householder Prior Approval process used to make a decision on these is available from the Documents part of the page.
From 15th April 2015 permitted development rights been amended and extended including changes which use the Prior Approval process where you formally apply to us. There is a fee of £80 for these applications. The number of Prior Notification processes has also increased. Please refer to the Documents part of the page for a full list and links to the forms, including the form for Completion Notification for Class A developments.
