How much will I have to pay?  

Eligible developments that receive planning permission from 1 September 2013 will be charged in accordance with the rates set out in the Charging Schedule. The amount payable is calculated when planning permission is granted.

Can I pay in instalments? 

If the liability is over £50,000 payment can be made in instalments as set out within the Instalment Policy that allows payments to be spread over a longer period of time. Please note that this Instalment Policy will not be available if liability has not been assumed and Commencement Notice has not been submitted before the relevant development commences or if payments are not made in time.

  1. Online: The best way to make a payment is by paying online:

If the CIL remains unpaid, or the process is not followed correctly, the council may take any or all of the following actions, based on the CIL Regulations, to recover the debt.

  • Seek authorisation from the courts to seize and sell assets to recover the CIL due
  • Seek committal to prison

How is the CIL calculated? 

The Community Infrastructure Levy (CIL) is calculated per square metre.

The calculation involves multiplying the CIL charging rate by the net chargeable floor area (based on Gross Internal Area), and factoring in an index figure to allow for changes in building costs over time.

The full calculation is set out under CIL Regulation 40

Existing floor area that has been in continuous lawful use for a period of 6 months within the 3 year period preceding development being permitted can be used as deductible floor area in the calculation of the CIL liability. The onus is on the applicant to demonstrate continuous lawful use.

Current indexed CIL rates are detailed in the Charging Schedule section.

How is Gross Internal Area calculated? 

Gross Internal Area (GIA) measured to the internal face of the perimeter walls of each floor of the building, including circulation and service space such as corridors, storage, toilets, lifts etc and the existing floor space of a building. Generally, any structure with 3 or more walls and a roof is considered to be ‘internal’ floor space and therefore chargeable. Buildings ‘into which people do not normally go’ are exempt from CIL. These include buildings into which people go intermittently for the purpose of inspecting or maintaining fixed plant machinery.

The change of use of a floor space where a self contained residential unit will be formed is also chargeable if the existing continuous use cannot be demonstrated.

Is there are right to appeal against the Community Infrastructure Levy charge? 

Appeals can be lodged against some aspects of the CIL charge. The full range of appeals available are detailed in this table

Further information regarding the appeals process are detailed within Planning Practice Guidance

Further details regarding appeals relating to CIL enforcement and surcharges are detailed within the Planning Inspectorate guidance
