CIL Calculator 

Terms of Service

This calculator will give you an indication of the amount of CIL owed on a project, given the parameters you supply. It is not intended as a final representation of your total liability, and does not constitute legal advice. As your application progresses you will be issued a Liability Notice and Demand Notice, which will contain the final breakdown of CIL owed on a development. The amount set out in the Liability Notice and Demand Notice is the binding amount you will need to pay.
You should not rely on the calculator to make decisions which depend on the amount of CIL liability.

*To get credit for existing floorspace to be retained and/or demolished it must have been in lawful use for a continuous period of 6 months out of the 3 years prior to the time when the planning permission first permits the development (for all planning applications except phased and outline applications this is the date the planning application was granted permission. For phased applications this is when the final approval is given under any pre- commencement condition for that phase. For outline permissions this is on the day of final approval of the last reserved matter associated with that phase).
 
Other reliefs and exemptions may be available. Please visit the Waltham Forest CIL and Mayor's CIL sections on the Waltham Forest website or visit the Planning Portal for more information.
