CIL Indexation

CIL payments must be index linked from the year that CIL was introduced (2014) to the year that planning permission is granted. The index used up until December 2019 was the national All-in Tender Price Index published by the Build Cost Information Service (BCIS).

From January 2020 the RICS CIL Index is used to calculate CIL liability in accordance with Schedule 1 of the CIL Regulations 2010 (as amended).

The RICS All-in Tender Price Index for 2014 (CIL implementation) was 235.

The RICS CIL Index for 2020 was 334.

The RICS CIL Index for 2021 was 333.

The RICS CIL Index for 2022 was 332.

The RICS CIL Index for 2023 is 355.

Further information on the CIL index linking calculation can be found in Schedule 1 of the CIL Regulations 2010 (as amended).
