Community Infrastructure Levy (CIL)

Please visit the CIL Fund page for details of the next CIL funding round. 

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 2024. This shows the rates that will be applied to permissions granted during the calendar year 2023. 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. 

More information about the process can be found on our how will CIL affect my development? webpage.

All the relevant forms can be found on our CIL Forms webpage.

You can still help to house Ukrainian refugees if you have had CIL Annex Relief granted for your development.  Please contact for information on this. For more information on the Governments Homes for Ukraine scheme in Cornwall, please visit the Help for Ukraine page
