Community Infrastructure Levy (CIL)

How CIL is calculated

CIL charges are calculated in line with Schedule 1 of The Community Infrastructure Levy Regulations 2019.

In most cases, the amount of levy that is payable is calculated by multiplying the additional gross internal area by the rate for a particular development type, taking the rate of indexation into account. The rate is set out in our charging schedule.

You can offset exiting floorspace on change of use and demolition of existing buildings if you (the applicant) can provide evidence to show they've been in lawful use for at least six continuous months within three years before the permission date.

Where part of an existing building's been in lawful use for a continuous period of six months within the last three years, parts of the building to be demolished or retained can be taken into account. The way those parts are taken into account is set out in the formula in Schedule 1 of The Community Infrastructure Levy Regulations 2019.

If an existing building does not meet the six month lawful use requirement, its demolition (or partial demolition) is not taken into account. However parts of the building to be retained as part of the chargeable development can still be taken into account, if the intended use matches a use that could've been carried out lawfully without requiring new planning permission. The requirements are set out in Schedule 1 of The Community Infrastructure Levy Regulations 2019.
