CIL phased developments

How to apply for your development to be introduced in phases

Phased development applications

Phased development applications may only be submitted for:

  • a minimum of two plots per phase
  • any planning applications type with no more than 10 plots

If you want a development to be phased, you'll need to complete a CIL phased development form (Form 0a).

You must submit form 0a, and we must acknowledge it before work starts on site. 

Once we've acknowledged your request, CIL will only be payable on each commenced phase, instead of on the commencement of the first unit.

Before starting work on each phase, you must submit a Commencement Notice (CIL Form 6). This must be submitted and received by us at least one day before starting any work.


To ensure that the CIL collection process runs smoothly, we've been given a stringent set of enforcement powers.

Please visit our CIL surcharges page for more details.
