The phasing of payments should be taken into account in any viability assessments, as this will assist with cash flow.
Relief and Exemption from CIL
If the development is not eligible for social housing relief, there are other reliefs and exemptions that may apply.
Further information on relief and exemption from CIL can be found on the National Planning Practice Guidance website.
Or on The Royal Borough of Kensington and Chelsea website.
