2. How much CIL do I pay?
Any new development, including change of use, that falls within the CIL Charging Schedule (residential and out of town retail) will be liable. To view this on a map follow the link to CIL charging areas
The charging schedule showed the amounts payable per square metre of floorspace in a development when it was first introduced in 2014.
The floorspace is measured using the Gross Internal Area as defined within the RICS Code of Measuring Practice
Since 2020 the CIL regulations state that the index rate to be used for each calendar year is the RICS CIL index as at 1 November of the previous year as published by (previously it was the BCIS index).
To calculate it for any year use the following formula:
Original CIL rate X Square Metres of Chargeable Area X Index for current year ÷ Index for 2014 (year of adoption).
For 2020 this is:
CIL rate X chargeable area X 334 ÷ 239
The CIL regulations require the charging authority to publish an annual CIL rate summary statement (with effect from 2020)
Further details on what the Community Infrastructure Levy (CIL) is and how it operates can be found on the Government guidance pages.
