Introduced in 2010, the Community Infrastructure Levy (CIL) is a tool for local councils to help raise funds from developers to deliver infrastructure such as new schools, open space or public transport.  

CIL is charged for certain types of development in the area. We started our CIL charges on 1 August 2015. 

Our process to adopt CIL

We adopted our CIL charges as follows:

Types of development liable for CIL 

The following are liable for Community Infrastructure Levy (CIL):

  • development comprising 100m² or more of new build floorspace 
  • development of one or more dwellings (a house, flat, or other place of residence)
  • the conversion of a building that is no longer in lawful use (not used for at least 6 months within the last 3 years)

If you submit a planning application which includes any of the above, you need to supply further information for us to calculate the CIL liability.

Where you have an undecided planning application, we may ask you for additional CIL information as liability occurs at the decision stage, not when the application was submitted.

In some limited cases, development which falls into the above categories will not require planning permission, but may still be liable for CIL. This is known as chargeable development and you need to tell us about it.

Application forms

Before you start you will need to download and save any form(s) before completing them using Adobe Reader desktop software/mobile app or full Adobe Acrobat software.

All CIL forms are available from the planning portal, however the following are most commonly used.


Form 0: CIL questions or additional information

This form must be submitted with all planning applications where the floor space created by the development is 100 square metres or more or for the creation of a dwelling(s). Further guidance is available for completing this form.


Form 1: assumption of liability

Once a decision notice is issued, a liability notice will be sent to the applicant/agent with the amount liable. This form is required to confirm who will be liable to make the CIL payment. It is also required if the customer wishes to claim relief, as relief can only be claimed once the person has assumed liability to pay CIL.


Form 2: claiming exemption or relief

This form is used when claiming either charitable or social housing relief. It needs to be received and a decision on the granting of relief issued prior to any work commencing on site. If work commences prior to a decision then relief will not be allowed.


Form 4: transfer of assumed liability

This form is used if, at any stage prior to the start of the development, the person who has assumed liability for CIL wishes to transfer liability to another person. An example might be that the development is being sold.


Form 6: commencement notice

This form must be submitted by the person liable for CIL at least 1 day prior to the development commencing. We recommend emailing the completed form to ensure it is received. The implications of not submitting this form on time would result in any relief being revoked and a possible surcharge.


Form 7: self build relief exemption claim form (part 1)

This form can be submitted along with the application if the applicant wishes to claim self-build relief, or should be submitted prior to any work commencing on site. A decision on relief must be granted and a commencement notice (Form 6) submitted to the CIL team at least one day before commencement, otherwise relief will be revoked and the liable person will be required to pay the full amount of CIL.


Form 7: self build relief exemption claim form (part 2)

This form must be submitted within 6 months of completion of the self build residential building, together with the evidence detailed in the form. Failure to submit this form will result in relief being revoked and the liable person being required to pay the full amount of CIL.

More information about the Community Infrastructure Levy and how it works can be found in our supplementary planning guide to CIL and Section 106 planning obligations, on the planning portal and at GOV.UK . You can also view a summary of the key steps for the CIL process.

Exemptions and reliefs

Certain developments may quality for a CIL exemption or relief. It is important to follow the correct process and claims procedure or you may become liable for the full levy charge. Further information and forms are available in our supplementary planning guide and on the planning portal. 


You may appeal if you disagree with a decision relating to the calculation and enforcement of CIL.
