Restricted Electrical Works

Restricted Electrical Works under the Electricity Regulation Act 1999, as amended, are defined as electrical works that can only be carried out and must be certified by a Registered Electrical Contractor (REC). Restricted Electrical Works encompass most electrical works in a domestic premise.

From 01 October 2013, anyone wishing to carry out Restricted Electrical Works must be registered with Safe Electric. Parties that carry out Restricted Electrical Works, but are not registered under the Safe Electric scheme, will be subject to prosecution.

Controlled Electrical Works

Controlled Electrical Works are works that require certification if completed by a REC. Most electrical works in commercial and industrial environments are covered under the scope of Controlled Electrical Works. While the CER recommend that RECs are hired to complete these works, it is not a legal requirement that only RECs carry out Controlled Electrical Works.
