Permitted development
Permitted development rights are a national grant of planning permission which allow certain building works and changes of use to be carried out without having to make a planning application.
If the development benefits from permitted development rights but is also is of a sufficient scale to be liable for CIL (over 100 sq m extension, creation of a new dwelling or conversion of a building no longer in use) it is the responsibility of the developer to serve a notice of chargeable development to us prior to the development commencing.
The CIL charge will then be calculated and applied just as though planning permission had been issued.
