Indexation Guidance Note
All CIL Liability Notices issued by the Council from 2 January 2017 will include indexation in the calculation of the chargeable amount. The calculation of the CIL chargeable amount is defined by the CIL Regulations 2010 (as amended).
The indexed rate for any given year is set on 2 January and uses the index figure for 1 November of the preceding year.
Calculation of the chargeable amount
The calculation of the CIL chargeable amount is set out in Schedule 1 of the Community Infrastructure Levy Regulations 2010 (as amended). CIL is calculated by multiplying the net increase in gross internal floor area (sqm) by the relevant CIL rate (£/sqm), plus any indexing for inflation/deflation (between the year in which planning permission was granted and the year in which the charging schedule took effect).
R x A x IP
- R is the CIL rate in £/sqm
- A is the net increase in gross internal floor area (sqm)
- Ip is the All-in Price Index for the year in which planning permission was granted
- Ic is the All-in Price Index for the year in which te charging schedule started operation
