Community Infrastructure Levy

The CIL calculator above was produced by the Greater London Authority (GLA) and TfL to indicate the likely level of CIL payable. This is for guidance only. The collecting authority is still required to calculate the correct levy in accordance with the current regulations.


The Levy will be charged by London boroughs on most developments in London at the following rates:

Zone 1 boroughs - £50 per square metre

Camden, City of London, City of Westminster, Hammersmith and Fulham, Islington, Kensington and Chelsea, Richmond-upon-Thames and Wandsworth

Zone 2 boroughs - £35 per square metre

Barnet, Brent, Bromley, Ealing, Greenwich, Hackney, Haringey, Harrow, Hillingdon, Hounslow, Kingston upon Thames, Lambeth, Lewisham, Merton, Redbridge, Southwark and Tower Hamlets

Zone 3 boroughs - £20 per square metre

Barking and Dagenham, Bexley, Croydon, Enfield, Havering, Newham, Sutton and Waltham Forest

Applying for planning permission

Applications for planning permission should be submitted to the relevant local planning authority.

Your local planning authority will apply the Levy and is responsible for its collection on behalf of the Mayor.

If you require further information, guidance is available on the Mayoral Community Infrastructure Levy page on the GLA website.


There are a number of developments that may be exempt from the Mayoral CIL. They include:

  • Health and education uses
  • Social housing provided by local housing authority, registered social landlord or registered provider of social housing and shared ownership housing
  • Charities, where the development will be used for charitable purposes
  • Structures or buildings that people only enter for the purpose of inspecting or maintaining fixed plant or machinery
  • Domestic house extensions
  • Proposals that do not result in additional floorspace or result in additional floorspace of 100 square metres or less (unless it is for the creation of a separate dwelling)

Exemptions are detailed in the CIL regulations issued by and available on the website.

As the Levy is a non-negotiable payment, it is recommended that any question of an exemption is discussed with the relevant local planning authority.

Information for boroughs

CIL Collection Group

The CIL Collection Group (CCG) is a forum of officers from local planning authorities, TfL, GLA, London Revenues Group, Department for Communities and Local Government and the Planning Inspectorate. It was established to look at issues around the implementation and collection of the Mayoral CIL.

Borough CIL Progress Tracker

We produce a regular 'Tracker' of progress for borough CILs. These are updated from CCG meetings and communications between TfL and boroughs.

CIL reporting to TfL by boroughs

All London Collecting Authorities report progress on CIL liable developments and collection of CIL receipts to TfL on a quarterly basis. See the standard form for payment details.

CIL Liable Planning

The developer(s) must complete the CIL Liable Planning Application and returned it to the respective authority. The local authority can then establish whether or not a development is liable for a CIL charge.
