Calculating CIL charges and making payment

CIL charges

Following public consultation exercises and an Examination in Public of our draft CIL Charging Schedule in May 2015, the independent examiner's report and recommendations were received in July 2015. The Charging Schedule (as amended by the examiner) was adopted for use at a meeting on 21 October 2015, to take effect from 1 April 2016.


In calculating individual charges for the levy, regulation 40 (as amended by the 2014 Regulations) requires us to apply an index of inflation to keep the levy responsive to market conditions.

The index is the national All-In Tender Price Index of construction costs published by the Building Cost Information Service (BCIS) of the Royal Institution of Chartered Surveyors.

This index presents forecast figures, which are updated and finalised periodically. It is applied at the beginning of the calendar year and the rates have been indexed from 2017 using this formula.

Charging schedule

The CIL Rate depends upon which zone the development falls into. You will see from the Maps that the district is divided into three main zones:

  • Rural
  • Urban
  • Sustainable Urban Extensions (SUEs)
SNC Development type Levy per square metre Rate on adoption
2018 rate
2019 rate
2020 rate
2021 rate
2022 rate
Residential Urban Zone and SUEs 50.00 57.75 59.96 61.44 60.70 61.25
Residential Rural Zone (sites at or above affordable housing threshold) 100.00 115.50 119.93 122.93 121.40 122.51
Residential Rural Zone (sites below affordable housing threshold) 200.00 231.00 239.85 245.76 242.80 245.02
Retail 100.00 115.50 119.93 122.88 121.40 122.51
All other uses 0.00 0.00 0.00 0.00 0.00 0.00

Where part of a development would fall into the definition of residential and/or retail, that part of the development is subject to CIL at the residential or retail rate, as appropriate.


The affordable housing threshold is the level above which developments must provide affordable housing. This is currently 10 dwellings, in accordance government guidance.

Residential means development which falls into use classes C3 or C4. We do not consider that classes C2 and C2A fall within this definition.

Retail means development which falls into use classes A1, A2, A3, A4, A5 or

AA or which is described in Regulation 3(6) (d) of the Town and Country Planning (Use Classes Order) 1987 (as amended) (the sale of fuel for motor vehicles).
