Community Infrastructure Levy (CIL)

The Community Infrastructure Levy (CIL) is a charge on new development and is used to fund local infrastructure that will support future development. It can be used to pay for improvements to community infrastructure such as sports and community facilities, schools, parks, playspace, health facilities and the transport network.

CIL is charged on most new developments (new buildings or extensions) that involve the creation of one or more new dwellings, or more than 100 square metres of new gross internal floorspace.

Islington Council is the CIL Collecting Authority for developments in Islington and collects both the London Borough of Islington CIL, and Mayor of London's CIL.

Islington CIL

Following an Examination on the council's CIL proposals, the London Borough of Islington CIL Charging Schedule was approved at a meeting of the council on 26 June 2014, and the Charging Schedule came into effect on 1 September 2014. The Islington CIL applies to CIL liable developments granted planning permission on or after 1 September 2014.

For full details please visit Islington’s Community Infrastructure Levy (CIL) webpage. 

Mayoral CIL

The Mayor of London's CIL applies to CIL liable developments granted planning permission on or after 1 April 2012.

The Mayor's is used by the Mayor to fund the delivery of Crossrail.

CIL and Section 106

In most cases, CIL replaces the use of planning obligations in Section 106 agreements to secure contributions towards infrastructure from development. Section 106 agreements will continue to be used to secure affordable housing, to mitigate site- specific issues, and to address other policy requirements that cannot be dealt with through CIL, including Carbon Offsetting and Employment and Training contributions. The council is currently updating the Planning Obligations (Section 106) Supplementary Planning Document (SPD) to reflect the adoption of Islington's CIL and to take account of the upcoming Development Viability SPD.

Further information on Section 106 can be found on the Planning Obligations (Section 106) webpage.

Further information on development viability can be found on the Development Viability webpage.

Affordable Housing Small Sites Contribution

Islington Council requires a financial contribution from minor residential planning applications (below 10 residential units) towards the provision of affordable housing in the borough.

Contributions for off-site affordable housing for small sites will be secured through a unilateral undertaking (Section 106, Town and Country Planning Act, 1990), which site owners, including mortgagees, will be required to enter into before the planning permission is issued. Questions relating to the small sites contribution for a particular development should be directed to the planning case officer for that application.

This contribution is completely separate to the CIL charge.

Further information on this policy can be found on the Affordable Housing Small Sites Contribution webpage and the supporting documentation (Additional Requirements) webpage
