What is a Commencement Notice?


A Commencement Notice is a notification to a Building Control Authority that a person intends to carry out either works or a material change of use to which the Building Regulations apply.

The notice must be given to the authority, not more than 28 days and not less than 14 days before the commencement of works or the change of use. Once validated by the building control authority, works must commence on site within the 28-day period.

If the works don’t start within 28 days of the day the Commencement Notice is lodged, a new Commencement Notice must be submitted prior to the commencement of any works taking place.
