Calculate your Community Infrastructure Levy (CIL)

The Community Infrastructure Levy (CIL) is a charge on new development and will be used to fund improvements to infrastructure required in West Berkshire. Use the online calculator for an indication of how much CIL you will be liable to pay for a development.

Terms of use

This calculator will give you an indication of the amount of CIL owed on a project, given the parameters you supply. The calculator is based on the formula set out in regulation 40 of the CIL Regulations (2010) as amended, and the CIL rates set by West Berkshire Council.

It is not intended as a final representation of your total liability, and does not constitute the CIL determined by the CIL Charging Authority or legal advice.

As your application progresses, and after the CIL liable development is approved, you will be issued a Liability Notice and following commencement, a 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.

If you wish to commence your development and have not yet received a liability notice, please contact the CIL Team immediately.

Further, you should not commence development (including demolition) without confirmation of any relief/exemption for CIL from the CIL Team and without submitting a Form 6: Commencement Notice.
