3. CIL rates and calculation of liability
The CIL charging schedule sets out the chargeable rates.
The levy is charged in pounds (£) per square metre on new floor space (measured as gross internal area) of any given development at the rates shown in the table below.
It is possible for the gross internal area of any existing buildings on the site that are going to be demolished or re-used (ie conversion or change of use) to be deducted from the total floor space granted planning permission to ensure that the CIL liability is only applied to new floor space over and above what is already on a site.
To be able to deduct floor space that is to be demolished or re-used (ie conversion or change of use), the CIL Regulations require that a part of the existing building has to have been in use for a continuous period of at least 6 months in the 3 years prior to when planning permission first permits development. If this provision is not met the CIL liability is applied to the total gross floor space granted planning permission.
All liability notices will be adjusted in accordance with the national all-in tender price index for the year when planning permission is granted for the development. The index for a given year is the figure for 1 November for the preceding year in the national all-in tender price index published from time to time by the building cost information service of the Royal Institution of Chartered Surveyors.
For planning permissions granted in 2020, the multiplier based on the index is 334/224. The resulting CIL rates for this and previous years are shown below.
