What is a valid planning application?

A valid planning application has all the information we need to assess it. If any information is missing or wrong, your application will be made 'invalid' until you make the necessary updates. This slows down the application process, so it's best to carefully check what you need to submit so that you can get your application right the first time. 

What do you need to submit with your planning application?

Planning applications are made up of three types of documents:

  1. Forms - which are needed for all applications
  2. Plans and drawings - which are needed for most applications
  3. Supporting documents - which are needed for some applications

What are the most common reasons for invalid applications?

These are the most common errors we see in planning applications:

  1. There is no site location plan or it is missing a scale bar, north arrow or red line boundary
  2. Plans and drawings are missing a scale bar, north arrow or reference number
  3. There is no fire safety support document
  4. The application fee is wrong

You can avoid making these mistakes by reading all of our guidance before you submit your planning application.
