How CIL is collected, monitored and spent

The Community Infrastructure Levy (CIL) is collected by local authorities from developers of new building projects. It's a charge on new development, specifically triggered by new floorspace (100m² or more) or the creation of new dwellings. The collected funds are used to finance infrastructure required to support the development, such as transport schemes, schools, and other public amenities.  The funds are monitored through financial reporting and councils are required to prepare an annual Infrastructure Funding Statement (IFS).

When we receive money raised from Community Infrastructure Levy (CIL) we allocate:

  • 5% for setup and admin costs of CIL
  • 15 to 25% to the town and parish councils of where the income was generated - to spend on infrastructure projects which support development in their area

This amount differs depending on whether the town or parish council has an adopted neighbourhood plan:

Allocation of CIL according to neighbourhood plan
Neighbourhood Plan Portion of Levy
Yes 25% uncapped
No 15% capped at £10 per dwelling
  •  The remaining 70 or 80% of the CIL income is allocated for strategic infrastructure as follows:
    • 70% - West Sussex County Council
    • 20% - Arun District Council
    • 10% - other

Infrastructure Investment Plan

We have prepared an Infrastructure Investment Plan (IIP) covering the period 2022-2024 (3 years) which was reported to the Planning Policy Committee meeting on 25 January 2022 and subsequently approved at Full Council on 9 March . The IIP sets out the a shortlist of our priority projects for funding together with a CIL apportionment for each of the 3 years. It also includes a baseline (long list) of projects which may secure funding in future years or which may be added to when updated in year 3.

The pro forma below is used by infrastructure providers to enter details of potential projects that they would like to be included in the Investment Improvement Plan (IIP) or to update existing projects that are already included in the short list or long base line list.  We will be carrying out an 'light touch' update in March 2023.
