CIL Calculator

The Winchester City Council (WCC) Community Infrastructure Levy (CIL) Calculator has been developed by officers to assist developers and homeowners in calculating an indicative charge for CIL. It is not intended to provide a definitive answer; this will be calculated by WCC officers when the application is submitted for approval or prior approval.

Winchester's CIL does not apply to the part of the District that is within the South Downs National Park. The National Park has their own CIL Charging Schedule for the whole of their area.

Please Note:

  • Please enable macros to use the calculator, or use the sheet tabs at the bottom of the spread sheet to navigate between pages. 
  • The calculator may not be compatible with software used on Macs; if this is the case please refer to the CIL Regulations 2010 (as amended) for the calculation method.  Links to the CIL Regulations can be found on the following web page: CIL Charging in Winchester - Winchester City Council
