Community Infrastructure Levy

The Community Infrastructure Levy (CIL) is a charge we apply to new developments, to help to fund improvements to infrastructure.

We will still use S106 agreements, but only for site specific requirements and to secure affordable housing.

You can look at the Planning Portal for information about CIL, and to download the CIL forms.

1. Check if CIL applies

Developments will be liable for CIL if they:

  • add 100 square metres or more of new floorspace     
    This includes new and replacement buildings and extensions to buildings.
  • are residential properties that are either a new build or converted, regardless of their size
    This does not include converting a single house into two or more separate houses.
  • are the conversion or change of use of a building that has not been used for a period of time
  • are commenced under general consent
    This includes permitted development rights granted under the General Permitted Development Order 1995

To check if you need to pay the CIL charge, you should submit a CIL Additional Requirements Form when you submit your planning application.

In 2014, we set our Charging Schedule for different types of development. Each year since then, we have increased the charge using an index of inflation.

This year, the charges are:

  • £167.0168067 per square metre for Residential C3

  • £200.4201681 per square metre for Retail A1

  • £116.2436975 per square metre for Retail other

We are able to grant relief or exemptions from CIL. You can check if you are  eligible for relief or an exemption from CIL on the Planning Portal.
