Regulation 4 amends the Buildings (Registered Building Control Approvers etc.)(England) Regulations 2024 to add a reference to new regulation 40C.

(Amendment) (No.2) Regulations 2013 and the Building Regulations etc. (Amendment) (England) Regulations 2021. It also makes transitional arrangements in relation to cases where those savings apply, so that the amendments made by regulations 3 and 4 do not apply.
