How to find out whether you need to pay the Community Infrastructure Levy (CIL), and which forms you need to send.
The CIL is a planning charge for developers and landowners which is used to support development of local infrastructure. The CIL is charged per square metre on new developments, and applies to:
- new dwellings of any size
- any development where the internal area of a new building, extension or change of use exceeds 100 square metres
Please note that changes to the CIL Regulations came into force on 1 September 2019.
Please see the
Government guidance on CILExternal link for more information.
