  • new buildings (such as extensions) where the gross new build floor area comes to more than 100 square metres
  • a change of use from non-residential to residential use, when the building in question has not been occupied in its lawful use for a continuous period of 6 months in the previous 3 years

Development carried out under Permitted Development ("General Consent") may still be liable for CIL if it meets any of the above criteria.
