Community Infrastructure Levy (CIL)

What is CIL?

The Community Infrastructure Levy (or 'CIL') was introduced nationally in April 2010 and is governed by the CIL Regulations 2010 (as amended) (external link). It allows local authorities in England and Wales to raise funds from developers who are undertaking new building projects in their area. The money can be used to pay for a wide range of infrastructure that is needed to support new development. This can include things like transport schemes, green spaces and the maintenance of new infrastructure. The principle behind CIL is that most development has some impact on infrastructure and should contribute to the cost of providing or improving infrastructure.

From 1 September 2014, all developments that create more than 100sqm of new build gross internal area, or create a dwelling (irrespective of size) are liable for CIL - this includes permitted development. CIL is due upon the commencement of the development.


The current index, from 1 January 2020, is 1.409. This 'CIL Index' is set by the RICS.


If you have to pay CIL, you will need to send us specific forms and notices, at specific times. Failure to do so means we will impose penalties such as surcharges (up to £2,500), the removal of any instalments and the refusal/withdrawal of any relief granted to you. We will also take enforcement action to collect outstanding CIL charges; in the most severe cases this will include stopping development on site or taking court action. 

These guidance notes are intended as a summary of the relevant provisions. For detailed guidance, you should always refer to the CIL Regulations 2010 (as amended). You should seek your own advice if you are in any doubt as regards how CIL operates or affects your own position.


COVID-19: Please note that officers are currently working from home and so we advise all notices, and any other enquiries, are sent by email to to ensure that officers can receive and respond to them.  If you submit a notice but do NOT receive an acknowledgement of its receipt, you should contact the CIL Officer, via email, to confirm receipt before starting any development works. 

The Government have not made any changes to the CIL Regulations in response to Covid-19 and so all due instalments remain payable in accordance with your demand notice and its terms.
