The Community Infrastructure Levy (CIL) is a charge placed on development, such as new homes and extensions to homes, according to their floor area. This step-by-step guide to the process tells you which forms to submit and when you should submit them.
It is important that you follow this process, as otherwise we may apply a surcharge. All exemptions must be applied for prior to commencement. Evidence of continuous lawful use must be submitted within 28 days of your Liability Notice.
All the forms on this page are downloadable PDF documents from the Planning Portal website.

The CIL process begins when you submit a planning application.
You need to submit Form 1: Additional information with your planning application.
The form asks for details of new floorspace to be created by the development. It also asks for details of any floorspace to be demolished, which can be offset against the new floorspace calculation. It is in your interest to provide this information, especially where there are existing buildings in use on your site, in order to ensure that the CIL calculations can be completed correctly.
It is important that you inform us about who will be responsible for paying the CIL if permission is granted. Form 2: Assumption of liability needs to be submitted before validation of your planning application.
During the process, you may wish to withdraw or transfer liability of the charge, for example if you sell the site. If so, you need to complete and submit either Form 3: Withdrawal of assumption of liability or Form 4: Transfer of assumed liability.
Once planning permission has been granted, we will issue a liability notice to all relevant parties (as well as the landowner, if the two are different).
A revised liability notice can be issued at any point, and this will supersede the previous one.
The CIL regulations provide for exemption from CIL in the following circumstances:
Depending on the type of exemption you need, you will need to submit the relevant form from the list below.
The completed form must be submitted before development commences in order to obtain relief. We cannot process requests for relief retrospectively after commencement.
If any relief is granted, where relevant we will issue a revised liability notice, to reflect any changes as a result of the relief. This will supersede any previous notice we have sent.
The CIL regulations require the submission of a commencement notice by the liable party before starting the development.
It is vital that a commencement notice is submitted before development starts. The CIL regulations state that where a commencement notice has not been received before commencement, those liable will no longer be able to benefit from the instalment policy and surcharges may automatically be applied.
Once we have received a Commencement Notice, we will issue a demand notice. This notice will detail:
No commencement notice is required for developments where extension relief has been granted, or where the liable amount is £0 before any relief is applied.
If you have applied for a self-build exemption, the liable person must submit Form 7: Self-build exemption claim form part 2 within six months of completion of self-build housing.
You will need to provide the following:
You must also include one of the following:
Failure to submit the appropriate form and evidence within six months of completion of the development will result in the withdrawal of the exemption and payment in full of the liable amount.
If something occurs that disqualifies you from your exemption, you need to notify us within 14 days of the day the disqualifying event occurred. If we are not notified, surcharges will apply.
Disqualifying events include letting out a residential annex that had received annex relief within the clawback period of three years, or selling a property which had received self-build relief within three years of completion.
For all disqualifying events, refer to these CIL regulations on the UK Legislation website:
