Community Infrastructure Levy (CIL)

Please read our information on how we are supporting residents and businesses, as well as information on affected services.


Please be aware that there will be some delays in our response times which is unavoidable at the moment. The Council is committed to supporting our staff to work flexibly to enable a balance to be reached which means our officers may be working different hours.

Thank you for your understanding.

The Community Infrastructure Levy (CIL) Charging Schedule came into effect in Cornwall on 1 January 2019. This means that any development granted permission after this date may be liable to pay the levy.  

CIL allows local authorities to raise funds from new building projects undertaken in their area. It is governed by the CIL Regulations 2010 (as amended). CIL is charged as a fixed rate per square metre of new floor space created. The money raised can be used to help fund a wide range of infrastructure that is needed to support development. 

A development is liable for CIL if it:

  • creates a new dwelling of any size; or
  • creates over 100sqm of gross internal floorspace and
  • involves new buildings into which people normally go.

The CIL Charging Schedule sets out the rates charged on new development in Cornwall when CIL came into effect. It also details the types of development that will not be charged and those that can apply for exemption/relief from paying CIL. From 1 January 2020, indexation has applied to the adopted rates. These are set out in the Annual CIL Rate Summary 2021. This shows the rates that will be applied to permissions granted during the calendar year 2021. The summary document also shows the indexed rates for previous years.

The CIL Discretionary Relief Policy sets out additional relief available in Cornwall. Our Exemption Relief Guidance sets out how to complete some of the more difficult sections included in the exemption relief claim forms.

CIL Charging Authorities can choose to allow CIL to be paid in instalments.  Cornwall Council's CIL Instalment Policy sets out when payment of CIL would be due depending on the total amount of CIL payable. Please note that a new Instalment Policy came into effect on 1 April 2020. This will be applied to developments which commence on or after this date.
