Community infrastructure levy

The Community Infrastructure Levy (CIL) is a power which enables the Council to raise funds for infrastructure from new development.

It is levied on the net increase in floorspace arising from development. In Harrow there are two Community Infrastructure Levies:

The Mayoral CIL

The Mayoral CIL is charged at a rate of £60 per sqm,  and applies to all new development in Harrow of over 100sqm gross internal floor space. 

This rate excludes indexation, which will be calculated based on the date planning permission is granted. The rate has increased from £35, effective 1st April 2019.

Harrow CIL

We adopted its CIL on 16 September 2013 and it applies borough wide for certain uses of over 100sqm gross internal floor space.

The CIL was examined by the Planning Inspectorate and found to be legally compliant. It has been charged from the 1 October 2013.

Our charges are:

  • Residential (Use Class C3) - £110 per sqm;
  • Hotels (Use Class C1), Residential Institutions except Hospitals, (Use Class C2), Student Accommodation, Hostels and HMOs (Sui generis) - £55 per sqm;
  • Retail (Use Class A1), Financial & Professional Services (Use Class A2), Restaurants and Cafes (Use Class A3), Drinking Establishments (Use Class A4), Hot Food Takeaways (Use Class A5) - £100 per sqm
  • All other uses - nil.

In accordance with Regulations 73(A) and 73(B) of the CIL Regulations, the Council accepts infrastructure payment in the borough.

This payment is the provision of one or more items of infrastructure by a person who would be liable to pay CIL in respect of chargeable development on commencement of that development.

This is commonly known as 'infrastructure in-kind payment'. For information view the Council's Policy in Kind Land and Infrastructure Payments document.

For further information you can download the Charging Schedule.

You can use our online calculator for an indication of how much CIL you will be liable to pay for a development. The amount calculated will only be indicative as the CIL liability will depend on the indexation rate at the time planning permission is granted and the Council’s own measurements of the CIL liable floor area.

A formal Liability Notice showing the CIL charge will be issued shortly after planning permission is granted.

Harrow's Community Infrastructure Levy is underpinned by the following supporting documents:


The Council is committed to using CIL revenues and other funding sources to help deliver social, economic and environmental infrastructure to support and meet the demands arising from development.

The Infrastructure Report and subsequent revised Infrastructure Assessment and Delivery Plan were prepared in 2012 and the information within them will most likely have changed (for example, number of GP clinics).

The documents will be updated as part of any review of the Local Plan and Community Infrastructure Levy Charging Schedule. Prior to that, more current information on infrastructure should be obtained directly from the relevant infrastructure provider (i.e. NHS) / council department.
