Community Infrastructure Levy (CIL) process

Stage 5: Commencement notice (applicant) and acknowledgement (council)

At least one day before commencement starts, you must submit a commencement notice to us. This informs us when the development is going to commence, and forms the basis of the dates that CIL payments will become due.

Failure to submit this form prior to commencement, or not at all, or providing an incorrect commencement date will result in us deeming a commencement date. We can also issue a penalty surcharge. If you are eligible for instalments, you will also lose the right to pay by instalments. If you have been issued relief or exemption, you will lose the relief or exemption.

If you submit a commencement notice, and then want to change the commencement date, just submit a revised commencement notice.

Once development commences, liability cannot be withdrawn, although it can be transferred up to the date final payment is due. If you submit a Commencement Notice, and then transfer liability before final payment is due, we will acknowledge receipt and reissue the liability and demand notices to reflect the change in liability.

Commencement is classed as any material operation that is carried out on the relevant land. This includes the erection of a building, demolition of a building, digging of a trench, laying of underground pipes or mains, any operation to construct a road or any change in the use of land that is classed as material development.

See Regulation 7, and section 56(4) of the Town and Country Planning Act 1990


You can appeal against a deemed commencement date. This must be made to the Planning Inspectorate within 28 days of the date the Demand Notice was issued.

We will record and acknowledge receipt, in writing, of your Commencement Notice and issue a Demand Notice.
