CIL & S106 Rates

CIL & S106 Rates

The South Downs National Park Authority (SDNPA) has set out its levy rates in the SDNPA CIL Charging Schedule.  Levy rates are expressed as £ per square metre.

Within the South Down National Park residential developments (which includes extensions, annexes and holiday lets) are charged £150 – £200 per square metre and large format retail developments are charged £120 per square metre. The charging rate for all other types of development is set at £0 (zero) per square metre.

For residential developments there are different charges for two geographical zones, Zone 1 (£150 per m2) covers Liss, Petersfield, Midhurst, Petworth and Lewes, and Zone 2 (£200 per m2) covers all other areas.  To check which residential charging zone your development falls within please use the map below.

CIL Liability is calculated on a per metre squared basis, using Gross Internal Area (GIA) which is defined as the area of a building measured to the internal face of the perimeter walls at each floor level.  All GIA measurements are calculated using the RICS 6th Edition Code of Measuring Practice core definition of Gross Internal Area and excludes any specialist definitions.

There may be circumstances where the SDNPA and the person liable for the levy will wish land and/or infrastructure to be provided, instead of money, to satisfy a charge arising from the levy.  The CIL Infrastructure in Kind Policy sets out how this is calculated and operates.


The charging rates set out in the charging schedule are subject to annual indexation. Please see below for a summary of the charging schedule rates.

How was the charging schedule prepared?

In setting the rate the SDNPA has had to demonstrate that it will not threaten the ability to develop the sites and scale of development identified in the South Downs Local Plan.  In summary, the charging schedule was prepared and adopted as follows:

  • The SDNPA prepared its evidence base in 2014 / 15 in order to determine its draft levy rates, this included an assessment of the impact of any changes on the viability of development.
  • The preliminary draft charging schedule was published for consultation in September 2015 and in 2016 a draft charging schedule was prepared and published for consultation.
  • An independent examination of the charging schedule was undertaken and the Examiner published his recommendations in June 2016
  • On 31 January 2017 the SDNPA formally agreed that the CIL Charging Schedule shall take effect from 1 April 2017 across the entire National Park. This is confirmed through the publication of the Adoption Notice  and the Regulation 1 2 3 List
