Community Infrastructure Levy

What is the Community Infrastructure Levy?

The Community Infrastructure Levy (CIL) is a new fee that local authorities and the Mayor of London can charge on developments to fund infrastructure needed in the local area. CIL is payable on all developments granted full planning permission by the council that involve an increase in net floorspace of over 100m2, or involve the creation of a new residential units. We will be collecting the Mayoral CIL on behalf of the Mayor.

What do you need to do?

Complete a Community Infrastructure Levy additional information form and submit it with your planning application. This is so we can calculate the amount of CIL accurately. The CIL additional information form is part of our local planning application requirements. Read the CIL Form Guidance Notes
