The Community Infrastructure Levy (CIL) is a planning charge, introduced by the Planning Act 2008 as a tool for local authorities in England and Wales to help deliver infrastructure that supports development in their area. Local authorities have to decide how the infrastructure needs of the development proposed will be met and how these will be paid for.

We have adopted a CIL and have provided a Supplementary Planning Document (SPD) on how CIL and planning obligations work together.

Guidance on the CIL and your application

New development, including extensions to buildings, could be liable and CIL is charged per square metre of additional floor space. This applies to:

  • the creation of a new dwelling, regardless of size, including change of use to residential, regardless of whether or not it includes additional floorspace
  • other development of 100 square metres or more

CIL will generally not be required for house extensions

House extensions (and annexes) will either not be liable to CIL or will be entitled to self-build relief in most cases, so we do not require a CIL Form to be completed, unless the applicant either doesn’t have an ownership interest or doesn’t occupy the house as the main residence.

CIL also only applies if the extension is over 100 sq m gross internal floor space. You should check our guidance below if you are unsure or contact us.

Calculating the amount of CIL you need to pay

Calculate the amount of CIL payable using the CIL calculator. Please note that the CIL calculator does not include the additional indexing charge that has been applied since July 2016. The index in July 2015 was 254, as of July 2019 it is 336. Bear in mind that this represents an additional 32.28% on top of the charge generated by the CIL calculator and you will need to add this on yourself.

This index is updated annually and new CIL Regulations enacted in September 2019 will require a further index update to be applied every 1 January, starting in 2020.

Information required

If your development is liable for CIL, an additional information requirement form will be required for submission alongside the planning application form. 

Local CIL

We are required by CIL Regulation 59A to pass 15% of CIL receipts in the area of a local council to that council. In Sheffield, there are 3 local councils:

  • Bradfield Parish Council
  • Ecclesfield Parish Council
  • Stocksbridge Town Council

Where there are no local councils, CIL Regulation 59F requires us to use 15% of CIL to “support the development of the relevant area”. We have chosen to allocate this local CIL to individual wards and to use our Local Area Partnerships as a mechanism for making decisions on how to spend the local CIL.

How the CIL is spent

New CIL regulations have removed the requirement for authorities to publish a CIL Regulation 123 Infrastructure List. By 31 December 2020 this list can be replaced with an infrastructure funding statement. In the meantime the list remains a useful indication of infrastructure that may be CIL funded. 

Section 106 Planning Agreements

These new regulations also allow for CIL and Section 106 contributions to be used to fund the same infrastructure and allow us to seek monitoring fees for S.106 agreements.
