Community Infrastructure Levy (CIL)

When submitting a planning application, you will need to submit an Additional Information Form.

The form asks for details on new floorspace created by the development. It also asks for details of any floorspace to be demolished or converted, which may be offset against the new floor space when calculating the CIL charge. This is only applicable when existing buildings are in a lawful use and appropriate evidence is provided, see our Continued Lawful Use Guidance Note.

• Form 1: Additional Information Form

The Assumption of Liability form must be completed and returned to us to inform us who is liable for the CIL charge. A member of our team will contact you once your planning application has been approved with the form. You are welcome to submit this to us beforehand, via your case officer.

• Form 2: Assumption of Liability

You may later need to withdraw assumption of liability or transfer assumed liability, if you wish to sell the site.

• Form 3: Withdrawal of Assumption of Liability
• Form 4: Transfer of Assumed Liability

The following developments are exempt from CIL:

• Residential annexes and extensions
• Self-build houses and flats
• Social housing
• Charitable development

There is a different form that must be completed for each type of exemption. Exemption forms can be found on the Planning Portal. Completed forms must be returned to us prior to commencement of the development in order to obtain relief.

Disqualifying events mean you are no longer entitled to an exemption. These could 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. 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. For all disqualifying events, refer to the CIL regulations on the UK Legislation website.

Exceptional circumstances relief is available in the borough. Please see the Exceptional Circumstances Relief Policy for more information.

We will issue you with a Liability Notice detailing the CIL charge. At the same time, we issue the Commencement Notice, which you will need to fill out and return to us. The Commencement Notice provides us with the date development is expected to start on. It is essential that we receive this before development starts and if not, you will have to pay a surcharge and will no longer benefit from our instalment policy.

Note - a revised Liability Notice can be issued at any point, which will supersede the previous version.

• Form 6: Commencement Notice

Once we have received the Commencement Notice, we will issue a Demand Notice asking for payment. This must be paid within 60 days of issue, unless an instalment plan has been agreed as per our instalment policy.

If you have applied for a self-build exemption, the liable person must submit the Self-build exemption claim form part 2 within six months of completion of self-build housing.
