Community Infrastructure Levy

The Community Infrastructure Levy (CIL) is a charge placed on development, such as new homes and extensions to homes, according to their floor area.

You will need to pay CIL if you are:

  • creating a new dwelling or residential annex (of any size)
  • increasing the gross internal floor area by 100 square metres or more.

The CIL process begins when you submit a planning application

If you need to pay CIL, you can follow a step-by-step guide and download all relevant forms on our Community Infrastructure Levy Process page.

If your development consists of one or more new dwellings in European nature conservation areas within New Forest, you will have to pay a financial contribution.

Calculate your CIL charge

The CIL charge for all residential development for 2020, including sheltered housing and extensions, is payable at a rate of £102.40 per square metre (rounded). The formula to calculate this is index-linked and published by the Royal Institution of Chartered Surveyors (RICS).

To find out how much you will need to pay, use our CIL Online Calculator. The amount is linked to the year in which planning permission for your development was granted.

You can download our CIL Charging Schedule below. This explains the methods used to calculate the CIL and the rates within New Forest. Note that this document features the 2015 CIL rate of £80 per square metre, not the current rate of £102.40 per square metre (rounded) which is calculated at the 2020 index rate.

Calculating chargeable floorspace

The chargeable floorspace is measured as the gross internal area (GIA) of the property. This is per floor and includes all buildings, including garages.

More information can be found in a guidance document on the RICS website called Code of Measuring Practice.

Using your existing floorspace

Existing floorspace is not taken into account when determining CIL liability. It is possible to receive a reduction on your CIL charge, if the existing floorspace has been in continuous lawful use for six months in the three-year period to when permission is granted.

It is your responsibility to provide evidence to demonstrate the continuous lawful use. To demonstrate this, you can submit a combination of the following:

  • Copies of leases.
  • Electricity or gas bills for the six-month period.
  • Business rates or council tax bills and payments. (The Local Planning Authority does not have access to this information, as it is data protected.)
  • Redacted bank statements to show paid rent (where an informal arrangement exists).
  • Confirmation from a letting agent or solicitor advising of the period of occupancy.
  • An affidavit.

We will require further evidence of continuous use if it is not evident from the information supplied. We will not consider the existing floor area as deductible floor area unless the applicant demonstrates this.

Appealing during the CIL process

Appeals can be lodged against some aspects of the CIL charge. The full range of available appeals are detailed in the document below.

If you disagree with the CIL liability calculated in the Liability Notice, you can request a review under Regulation 113 of the CIL Regulations. The review must be requested before the end of 28 days, beginning on the day on which the Liability Notice was issued.

When you need to pay

CIL payments are due when you start your development. You will need to complete and send us a Commencement Notice so we know when work is starting. From the Planning Portal website, you can download a Commencement Notice below.

Once you have completed this form, you can send it to the Planning team at any council office or email it to

We will then send you a demand notice. This has details on who is liable for payment and the amount payable, including any reliefs or surcharges.

The Demand Notice will also tell you the dates on which payments are due and whether you can appeal. You can find out more by downloading our Instalment Policy document below.

We may consider requests for part or full payment of the CIL by the provision of land or infrastructure. You can find out more by downloading our Payment in Kind Policy document below.

Monitoring of CIL

The money collected by CIL is divided into three areas:

  • Strategic spending.
  • Parish or Town Council spending: 15% capped at £100 per dwelling or 25% uncapped if a neighbourhood development plan is in place.
  • Administrative costs: five per cent.

The strategic spending CIL collection needs to fund infrastructure that supports development in the district. Our Infrastructure Delivery Plan has identified infrastructure projects that are required to deliver development up to 2036.
