Community Infrastructure Levy
Relief for self-builders and domestic extensions
In February 2014 the government introduced exemptions from CIL for self-builders.
Under this system, anyone who is extending their own property, or building a new property to occupy as their primary residence, can claim relief from CIL.
Please note: this is not an automatic process and must be applied for before work starts on site.
You must also assume liability for the development and send us a CIL Commencement Notice before work starts in order for the exemption to be valid.
- CIL Form 7 - Self build exemption claim part 1 on the Planning Portal
This form is used to make a claim for self-build exemption when a new dwelling is being constructed.
This should be used when the dwelling is going to be your primary residence on completion for at least 3 years. Please also pay attention to the declarations in section B.
- CIL Form 7 - Self build exemption claim part 2 on the Planning Portal
This form should be used for schemes where self-build exemption has been granted for new dwellings.
You should submit it to us within 6 months of completion in these cases, accompanied by the supporting evidence.
- CIL Form 8 - Self build residential annex exemption claim on the Planning Portal
This form should be used to claim for self-build exemption when the work being carried out is the creation of a residential annex, to be used as ancillary accommodation to the main dwelling.
- CIL Form 9 - Self build residential extension exemption claim on the Planning Portal
This form should be used to claim for self-build exemption when the work being carried out is a domestic extension that has a gross internal floor area of more than 100 square metres (extensions with a gross internal area of less than 100 square metres are automatically exempt from CIL and therefore do not require a claim to be submitted).
