Community Infrastructure Levy

The community infrastructure levy (CIL) is a charge levied on new buildings and extensions according to their floor area. The is money raised will help fund infrastructure to ensure that the borough grows sustainably. There are two types of CIL - a local CIL and the Mayoral CIL.

Developments where a CIL will apply

CIL will be applied to the gross floor space of most new buildings and extensions to existing buildings:

  • if the internal floor area will increase by 100 square metres or more
  • or if a new dwelling is created, even where the additional floor area is below is below 100 square metres.

CIL does not apply to:

  • buildings which people only go to occasionally, for example a plant that people visit only occasionally for inspections
  • development that does not consist of buildings
  • social housing and floor space to be used for charitable purposes
  • development built by a self-builder.

The amount of CIL payable relates to the size, type and location of the new development. To help calculate whether your development is CIL-liable, send a completed additional information requirement form as part of your planning application:
