Application forms for planning with guidance
This page tells you how to submit a planning application online, download forms, make a payment and where to get more help and advice.
Submitting applications online
You can use the Planning Portal to submit and pay for your application online. If this is the first time you’ve used the Planning Portal service, you will also need to register. Registration is easy and you can complete your application form, upload supporting documents and pay fees online.
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. For definitions of development types including major and minor applications please see our Development Types and Definitions document.
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 pay your fee online on our website, by cheque payable to Cornwall Council or via the Planning Portal.
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.
Validation checking service
We also provide an optional validation checking service to help speed up the registration of your application. The service includes meeting with you by appointment to go through your application and check that it meets the local and national validation requirements.
