What you need to do for CIL

Whether you believe your development is liable or not you should complete the CIL Additional Information Form:

When you receive your decision notice granting planning permission it will indicate if we think your application is CIL liable, however this may be subsequently revised by the CIL Team upon their review of decisions issued. Once the planning decision notice has been issued by the Council, check with the CIL Team to confirm if your development is CIL liable.

Applications liable for CIL 

If your application is liable for CIL you must ensure the following forms are completed and returned to the Council before starting any development.


It is also your responsibility to notify us if:

  • There is a change in the liable party (please use CIL form 2 Assumption of Liability, and form 3 Withdrawal of Assumption of Liability or form 4 Transfer of Assumed Liability)
  • The liable party's contact details change
  • If any buildings are demolished before the CIL liable date, defined below
  • If, prior to the CIL liable date (defined below), any buildings to be demolished or converted change in their eligibility to be deducted from your CIL liability. For example, if existing buildings that were "in use" for a continuous period of at least six months cease to be "in use" or, conversely, are brought into use

If you do not complete all the necessary forms before you start development you will no longer be eligible to request a review or appeal against our assessment of your CIL liability and you will be subject to additional surcharges and late payment interest. If you are uncertain about which forms you need to complete please contact the CIL team before you intend to start development, to avoid any unnecessary expense.

CIL liable date 

The CIL liable date is the 'day planning permission first permits the chargeable development'. This is defined in the CIL Regulations as the date at which development may commence.

The CIL liable date is normally the date the planning permission is granted, unless your development is an outline or a phased development. In those scenarios please contact the CIL team to discuss your CIL liable date.

Make a payment 

Precise details of your payment arrangements and options will be contained in the Demand Notice that will be sent following submission of a valid Commencement Notice.

Once you have received your Demand Notice, you can pay securely online

Reviews and appeals

If you think that we have made a mistake in calculating the chargeable amount you must, prior to commencing the development and within 28 days of the liability notice being issued, submit in writing a request for a review to:

CIL Administrator
Wandsworth Council
The Town Hall
Wandsworth High Street
SW18 2PU

Or by email to cil@wandsworth.gov.uk

If you are still unhappy with the calculation following this review, you can appeal to the Valuation Office Agency. This must also be done before the development starts and within 60 days of the liability notice being issued.

If a development begins without a CIL commencement notice being submitted, the Council will deem a commencement date and apply surcharges that must be paid. If the Council has deemed the commencement date of the development and you wish to challenge that date, or if you think the Council has applied surcharges incorrectly, you may submit an appeal to the Planning Inspectorate. The appeal must be made within 28 days of the date the demand notice was issued or the surcharge(s) was applied.
