Community Infrastructure Levy (CIL)

Find out about our CIL charges on developments and how to pay it.

Payment process


All CIL forms are available at the Planning portal.

The CIL legislation requires that you, the applicant or liable party, must follow the processes below or incur penalties for not doing so.

CIL liability must be registered as a land charge and on undertaking the above steps we will be able to issue a liability notice which will set out the amount of CIL that will be required if the planning permission is implemented. Remember, payment of CIL only becomes due if a planning permission is implemented.

Liable developments

Developments that create new-build floorspace with a gross internal floorspace (GIA) of 100 square metres or more would be liable to pay both the Mayor’s and Westminster’s CIL. A development involving the creation of a dwelling and new-build floorspace of any size would also be liable to pay both CILs.

Planning permissions for this type of development, including those subject to planning appeals, or enforcement appeals and permitted development, could potentially be liable to pay CIL. Developments granted permission through a general permitted development order may also be liable to pay CIL.


CIL Regulations 2010 (as amended) provides the formulas used to calculate the applicable CIL charges for each development that is deemed to be liable.

Developers must provide sufficient information to allow the council to determine whether the development is liable to pay CIL and to calculate the charges accurately from the floor areas provided. 

Collection, monitoring and enforcement of CIL

The CIL payment process is set out in legislation and must be followed. Financial penalties may be applied for failure to do so.

If a development is liable for the CIL and is commenced, payment is mandatory. There are strong enforcement powers and penalties for failure to pay, including stop notices, surcharges, late payment interest and prison terms.

Westminster City Council is implementing a Westminster Community Infrastructure Levy (CIL) taking effect on 1 May 2016 which will be charged alongside the Mayor of London’s CIL which took effect on 1 April 2012.

Payment by instalment

This policy will apply to payment of both the Westminster and Mayor of London’s CIL.

Infrastructure payments

We have given notice that in some circumstances it may accept payment of CIL in the form of infrastructure of a value equal to the money amount that would otherwise be payable and which can be shown to support the development of Westminster.

Infrastructure payments cannot be made for infrastructure required to make a development acceptable in planning terms. Any developer considering making an infrastructure payment should contact the council as early in the process as possible.

Governance of CIL expenditure

We are now working on CIL governance issues including how the processes of collection, spend, monitoring and reporting will be overseen. Recommendations will be brought forward by consideration by cabinet shortly.

It is worth noting that we are a long way off appreciable CIL receipts as CIL is not payable until the commencement of development, and allocation of CIL receipts is unlikely to happen until 2017 or 2018 at the earliest. 

To support implementation, below we have published a list of infrastructure, which may be funded wholly or partly by CIL.

Regulation 123 of the Community Infrastructure Levy Regulations 2010 (as amended) restricts our ability to use section 106 agreements to support delivery of infrastructure on the list.

Furthermore, we have agreed to a CIL Spending Policy Statement to help determine how individual infrastructure projects are allocated funding. This includes a range of eligibility criteria for both the 'strategic' and 'neighbourhood' portions of CIL.
