The Community Infrastructure Levy Regulations 2010 (as amended) allows for a charge on all new development to help fund infrastructure projects to support the development in the local area. CIL is a non-negotiable financial levy and is calculated on the Gross Internal Area of development.

All approved development in Maidstone that results in the following may be CIL chargeable:

  • New build residential floorspace of more than 100sqm.
  • The creation of a new dwelling if less than 100sqm (including retirement and extra care homes).
  • The conversion of a building to create a new residential dwelling (including through prior notification).

Maidstone has an adopted charging schedule which provides further details on the charging rates of the Community Infrastructure Levy in the borough and those developments that can be made exempt: Community Infrastructure Levy charging schedule - Maidstone Borough Council

Note: Residential development, including extensions over 100sqm, annexes, self-build homes, social and charitable housing will also be CIL liable. However, a relief or exemption for these may be applied for which a separate approval must be granted by the Council.
