Community Infrastructure Levy (CIL)

The Community Infrastructure Levy (CIL) is a charge levied on floor space arising from development in order to fund infrastructure that is needed to support development in an area.

Brent CIL was formally introduced from 1 July 2013.

We are also a collecting authority for the Mayor of London's CIL ‘Mayoral CIL’ which was introduced from 1 April 2012. ‘Mayoral CIL 2’ was introduced from 1 April 2019.


A CIL Calculator has been created to provide developers with an estimate of any CIL charge payable on a chargeable development.  It is not a final confirmation of liability, and does not constitute legal advice. Formal determination of the CIL liability will be made by Brent Council and a Liability Notice with be issued if your application is approved.

S106 agreements

If you are undertaking a large development in Brent, most cases,  will still be required to enter into a legal agreement under S106 of the Town and Country Planning Act 1990 (as amended) to secure other obligations to make the development acceptable in planning terms such as affordable housing and sustainability standards.
