You can use the Planning Portal to submit and pay for your application online. 

Planning Portal

Planning Portal is a service to submit planning applications electronically. Registration is easy and you can complete your application form, upload supporting documents and pay fees online.

It should be noted that this site is not run by Cornwall Council. If you experience any difficulties with this website please contact or 0333 323 4589

Submit application via the Planning Portal

Please provide plans (preferably A3 in size) as a pdf, no larger than 5MB each. Please include the type of drawing, site name, and paper size in your file titles. If you are submitting a major application, you may be asked to provide additional paper copies of the plans or the information on a disk.

Most planning applications need a site location and block plan showing the site you are planning to work on in red and other land in the same ownership in blue.  You can obtain site plans from the Planning Portal using the Buy a Plan service.

You can also download planning application forms and submit them via email or hardcopy. If submitting via hard copy, please note that we only require one hard copy of everything. This copy will be scanned upon receipt and disposed of after 21 days, therefore please do not submit any original documents. If you’re unsure which form you need, please contact us.

Cornwall Council has declared a climate emergency. We need to increase electronic working to support this. A charge was introduced on 4 January 2021 for handling planning applications and associated document submitted on paper.  This is on a cost recovery basis.

The charge per hard copy planning applications are:

  • £100 for major applications
  • £50 for general and other applications

This charge will be in addition to any planning application fees.

We provide an optional validation checking service to help speed up the registration of your application.  The service, by appointment only, includes meeting with you to go through your completed application and check that it meets the local and national validation requirements.

You can view a list of the documents you need to include with your planning application using the links below:

You can view a list of fees and charges in our Fees and charges document. Further information on our fees can be found within our Planning fees and charges supplementary document. The Planning Portal Fee calculator takes you through a set of questions to help work out your planning application fee.  

You can pay your fee online on our website, by phone on 0300 1234 151, via the Planning Portal or via iApply.  

We offer an optional pre-application advice service which helps cut down on the number of unsuccessful planning applications.  As part of this service, we’ll research the history of the site, visit the site (if required), highlight areas for further investigation and provide a detailed written response which includes an opinion as to whether or not a planning application would be worth pursuing.
