A Commencement Notice is required to give notice to Building Control Authorities of the erection of such buildings, or classes of buildings, or the carrying out of such works, or classes of works, as may be specified in the regulations. The Building Control (Amendment) Regulations SI 9 of 2014 recommends the Building Control Management System (BCMS) site as the preferred means of electronic building control administration.
To apply for a Commencement Notice each party (owner, designer, builder and assigned certifier) to the notice must first register with the BCMS.
