Is your development CIL liable?

All applicants for full planning permission and reserved matters following an outline planning permission (and applicants for lawful development certificates and Prior Approval applications), are required to complete a CIL Additional Information Requirement (CIL AIR) form providing the information upon which any CIL liability can be assessed.

Please note from 12 June 2017 the CIL AIR Form is no longer required for Householder applications

To find out if your development is liable for CIL and how this may affect your planning application, please visit our planning applications section.


Guidance is also available on the Department for Communities and Local Government's planning practice guidance website.

Replacement dwellings and householder extensions

CIL charges are not normally applied to applications for replacement dwellings and householder extensions (unless the householder extension creates a new dwelling).

Please note: for applications to replace an existing dwelling, if the dwelling is demolished during the course of application being determined the proposed development, if approved, will be CIL liable as the net increase of 1 residential (Use Class C3) dwelling is liable for a CIL rate in the Bracknell Forest Council CIL Charging Schedule unless it is erected in Central Bracknell. This includes section 73 applications that propose an increase in floorspace to these type of developments that have been granted planning permission and where demolition has occurred before the decision.

If the dwelling is demolished during the course of the section 73 application being determined, the proposed increase in floorspace of the approved development is CIL liable. In addition, as demolition is considered to be development (Section 56 of the Town and Country Planning Act 1990 (as amended)), applicants would be unable to claim the exemption for self build housing that is contained in the CIL Regulations 2010 (as amended) (paragraph 54A and 54B) unless a claim for the exemption is made before the demolition has taken place.
