Permitted development - do I need planning permission

Some types of development do not need planning permission.  This is called 'permitted development'.  

From 6th April 2014 new permitted development rights will come into force using a Prior Approval process. The new rights include allowing the change from A1 and A2 to dwellings, agricultural uses to schools, nurseries or dwellings and from a shop to a building society or bank.  For full details please refer to the Town and Country Planning (General Permitted Development)(Amendment and Consequential Provisions)(England) Order 2014.  You will need to formally apply to us submitting the relevant information.
The rules can change so you should check what the latest position is before you begin to build.  
There is a fee of £80 for all prior approval applications.

Forms available:-
 - Prior Approval form for changes of use for Class J from offices to dwellings, Class K state funded schools/registered nursery and Class M flexible uses in agricultural buildings. Class MA agricultural building to state funded school/registered nursey, Class MB agricultural building to dwelling, Class IA Class A1 and A2 to dwelling. 

 - Prior Notification for change of use Class D (A1-5, B1, D1 & 2 to A1-3 and B1) and Class M (agricultural under 150 sq m) to flexible use. Class CA from A1 to bank, building society, credit union or friendly society.
- Completion Notification for Class A developments
 are available from the documents part of the page.

A form is available to apply for a  larger single storey rear extension with a guidance note to complete the form.
Information on the Householder Prior Approval process is available from the Documents part of the page.

Interactive guides on permitted development are available on External links. 

If you want us to tell you whether you need permission we offer this service for a fee.  Please complete the form on the Documents part of the page 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 if you want a formal planning decision you can apply for a Certificate of Proposed Lawful Development including for Proposed Works to a Listed Building.
Even if you do not need planning permission you may still need Building Regulations consent, please check from the Related Pages.
