How we work out the size of a development
We work out the size of a development using its Gross Internal Area (GIA). This is measured in accordance with the Royal Institute of Chartered Surveyors Code of Measuring Practice Go to https://www.rics.org/uk/upholding-professional-standards/sector-standards/real-estate/code-of-measuring-practice/ (opens new window).
What to do if you think you're liable for CIL
You can get a Planning Application Additional Information Requirement form and guidance from the CIL forms page at the Planning Portal website. If you apply through Planning Portal, you'll need to attach this form as a supporting document. Otherwise, you'll need to send us this form with your planning application.
If you will be paying the CIL, you must also download the Assumption of Liability Notice form from the CIL forms page at the Planning Portal website and send it to us.
We'll then work out if you need to pay CIL. If we give you planning permission, we'll also give you a Liability Notice telling you how much CIL you must pay.
