Community Infrastructure Levy (CIL)

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

Exemptions and relief from CIL

Your project may be exempt from CIL under certain circumstances. 

Find out about CIL exemptions on the GOV.UK website.

We make a number of discretionary CIL reliefs available.

We have given notice that we will make available the discretionary reliefs it is allowed to implement under the Community Infrastructure Levy Regulations 2010 (as amended).

These reliefs will apply as appropriate to the Westminster CIL but not to payment of the Mayor of London’s CIL:

Social housing

The council has decided to allow relief to be claimed with respect to the “discount market sale” social housing allocated in accordance with a marketing strategy agreed upon by the council.

Document

Charitable relief

We allow relief to be claimed for development by charities for investment purposes, where the whole or greater part of the development will be held by the charity as a charitable investment.

We also make available further relief for development by charities for charitable purposes that do not qualify for mandatory relief because this might comprise state aid under European Union law; in such circumstances, relief can be given where we consider it may be state aid but are satisfied that it is not of a nature requiring notification and approval by the European Commission.

Exceptional circumstances

We allow relief to be claimed in cases where a section 106 agreement has been signed in connection with a development and independent evidence is presented that satisfies the council that requiring payment of CIL would have an unacceptable impact on the development's economic viability.

We will also need to be satisfied that allowing the relief would not constitute state aid under European Union law, which requires notification to the European Commission.
