CIL annual indexation notice

Community Infrastructure Levy - Indexation Guidance Notice 2020

This is to provide guidance on how indexation will affect the Community Infrastructure Levy (CIL) for developments granted planning permission in Cheshire West and Chester from 1 January 2020.

All CIL Liability Notices issued by us in 2020 will include indexation in the calculation of the chargeable amount. The calculation of CIL chargeable amount is defined by the CIL Regulations 2010 (as amended):


  • R - the CIL rate for that use
  • A - the deemed net area chargeable at rate R
  • lp - the index figure for the year in which planning permission was granted
  • lc - the index figure for the year in which the charging schedule took effect

The index that must be used is set by the CIL Regulations 2010 (as amended). The index figure for any given year is set on 1 January and is the index figure for 1 November of the preceding year.

For permissions granted before 1 January 2020 the rates published by the BCIS All-In Tender Price Index apply. For permissions granted on or after 1 January 2020 the Royal Institute of Chartered Surveyors CIL index will apply.

The index figures that will be used to calculate indexation for Cheshire West and Chester’s adopted Charging Schedule in 2020 are:

 Year  Index Figure
 2017 (the year the charging schedule took effect) (lc)  286
 2020 (the year in which planning permission was granted) (lp)  334

More information regarding the latest indexation rate for CIL can be found on the RICS website.
