CIL Calculator
Terms of Service
This calculator will give you an indication of the CIL charge payable on a chargeable development, given the parameters you supply. The calculator is based on the formula set out in Schedule 1 of the CIL Regulations 2010 (as amended, 2019), and the CIL rates set by the Mayor of London and the London Borough of Islington.
It is not intended as a final representation of your total liability, and does not constitute legal advice. You should not rely on the calculator when making decisions which depend on the CIL charge amount. Formal determination of the CIL liability will be made by Islington Council when a Liability Notice is issued after a CIL liable application is approved.

Paying CIL in Instalments
Islington Council has a CIL Instalments policy in place and CIL charges will be payable in accordance with this policy. In cases where an Islington or Mayoral CIL charge is less than £500,000, the whole amount will be payable within 60 days of the commencement of the development. Where an Islington or Mayoral CIL charge is £500,000 or more, the amount will be payable in two or more instalments. The rules on paying CIL in instalments are set out in Regulation 70 of the CIL Regulations 2010 (as amended). The payment of CIL in instalments should be taken into account in any viability assessments, as this will assist with cash flow.
Phased Development
In cases where a development which has been permitted in phases, each phase is treated as separate development for the purposes of CIL, and each phase should be entered into a separate calculator. The phasing of payments should be taken into account in any viability assessments, as this will assist with cash flow.
Relief and Exemption from CIL
If the development is not eligible for social housing relief, there are other reliefs and exemptions that may apply.
In addition to social housing relief for affordable housing provision, a development may be eligible for relief or exemption from the CIL charge where it involves:
- Development where the owner of a material interest in the relevant land is a charitable institution and the development will be used wholly (or mainly) for charitable purposes;
- A self build annex or extension, or
- A self build dwelling.
Charitable relief is granted based on the charitable owner's share of the CIL charge, rather than the floorspace of the development. Self build exemption will apply to the floorspace of the annex/extension or dwelling.
Relief must be claimed by submitting the relevant relief claim form prior to the commencement of the development.
Islington Council and the Mayor of London do not have a policy for granting discretionary charitable relief or exceptional circumstances relief and will not accept claims made on this basis.
Further information on relief and exemption from CIL can be found on the National Planning Practice Guidance website at: http://planningguidance.planningportal.gov.uk/blog/guidance/community-infrastructure-levy/relief/
Final CIL Liability
Formal determination of the CIL liability will be made by Islington Council when a Liability Notice is issued after a CIL liable application is approved. Please note that the CIL charges produced by the calculator may be subject to change and may differ to the final calculation of CIL liability.
The final calculation of the CIL chargeable amount will be based on the final gross internal area (GIA) floorspace figures proposed as part of the approved development, and will depend on the following:
- Is the floorspace of existing buildings to be demolished or retained eligible for deduction from the CIL chargeable amount?
- Is the development eligible for relief or exemption from CIL?
- Has indexation been applied?
- Have any surcharges or late payment interest been applied?
