Charging authorities are required to spend the levy's revenue on what they see as the infrastructure needed to support the development of their area. The assessment of 'need' will largely by informed by the Infrastructure Delivery Plans (IDPs) published by each authority alongside their Local Plans. The levy is intended to focus on the provision of new or improved infrastructure and should not be used to remedy pre-existing deficiencies unless those deficiencies will be made more severe by new development. Chichester District Council will publish an annual CIL Infrastructure Business Plan setting out how it intends to spend monies raised through CIL.
