The rates shall be updated annually for inflation in accordance with the Building Cost Information Service (BCIS) of the Royal Institution of Chartered Surveyors’ All In Tender Price Index.

4.2. Parts 2 and 6 of the Community infrastructure Levy Regulations 2010 (as amended)
state that the following development will be exempt from CIL charges:

  • Development where the gross internal area of new build is less than 100 square metres, although this does not apply where the chargeable development will comprise one or more dwellings;
  • Buildings into which people do not normally go;
  • Buildings into which people go only intermittently for the purpose of inspecting or maintain fixed plant or machinery; and
  • Development where the owner of a material interest in the relevant land is a charitable institution, and the development will be used wholly (or mainly) for charitable purposes.

4.3. In addition, the CIL Regulations also allow exemptions to be claimed for self-build
housing, and residential annexes and extensions over 100 square metres (regulation
42A and 42B). Affordable housing will be eligible for Social Housing relief from CIL (regulation 49).
