Stage 1 - Submission of Planning Application and CIL Additional Information Requirement Form (Applicant)

All applications will require the submission of a CIL Additional Information Requirement Form (alongside all other application forms and supporting information), except for the following:

The information provided on this form will enable us to determine whether or not CIL is payable and to calculate the chargeable amount. Failure to supply this information will invalidate your application and lead to delays with your planning application.

If you think existing floorspace (to be used or demolished) should be deducted as part of the CIL calculations, you must be able to demonstrate it has been in continuous lawful use for at least six months in the last three years, prior to the development being permitted. You must supply evidence to support your claim. For more information see:

If no information is received, under Regulation 40, we can deem any existing floorspace to be zero when we calculate the chargeable rate.

All forms are available from and can be submitted via the Planning Portal.
