Prior Notification - Change of Use of Agricultural Building

Prior Notification - Change of Use of Agricultural Building to a permitted flexible use Checklist and Form

The Government grants planning permission for certain changes of use of existing agricultural buildings, known as permitted developments, which can be undertaken without a planning application if the necessary criteria are met. A prior notification process is in place. You can find more information on the Planning Portal about change of use (opens in new window) 

Please download the Prior Notification - Change of Use of Agricultural Building to a permitted flexible use Form (PDF) (opens in new window)

Please make sure your application includes all the right information, or it will be judged as invalid.

Application requirements 

You will always need: 

  • Written description of the proposed development (we recommend you use the form)
  • A plan indicating the site and showing the proposed development
  • The developer's contact address
  • The developer's email address if they are happy to receive communications electronically
  • Fee

You will sometimes need:

  • Flood risk assessment

Top tip: A flood risk assessment will be required if the cumulative floor space of the building or buildings which are to change use exceeds 150 square metres and are in Flood Zone 3, Flood Zone 2, or an area within Flood Zone 1 which the Environment Agency have formally told us has critical drainage problems.

For more details about when we need the information above, and what we expect, please see our guidance notes.

Top tip: if you are applying by post, please send three copies of all forms, plans and supporting information.
