How to calculate chargeable floorspace

The chargeable floorspace is measured as the gross internal area (GIA) and is per floor and includes all buildings, including garages. More information can be found in the Code of measuring practice RICS guidance (opens as a PDF).

Existing floorspace is not taken into account when determining CIL liability, but it is possible to receive a reduction on your CIL charge if the existing floorspace has been in continuous lawful use (PDF 198 KB).

When you need to pay

CIL payments are due when you start your development. You will need to send us a commencement notice so we know when work is starting.

We will then send you a demand notice which has details on who is liable for payment, the amount payable including any reliefs or surcharges. We only accept payment via BACS or card.

The demand notice will tell you the dates on which payments are due and whether you can pay in instalments (PDF 2MB).

Surcharges and enforcement

In some cases we may charge you an additional fee if you do not submit the right forms at the right time.

We can apply extra charges and interest to applications where there has been a:

  • failure to submit CIL Forms
  • failure to inform of a disqualifying event
  • late payment
  • failure to comply with information from us as the Charging Authority

A list of the surcharges is available to download.

Enforcement

We can also serve CIL Stop Notices which stop development until the outstanding levy has been collected.
