Electrical licences in WA are issued by the Electrical Licensing Board. Building and Energy, part of the Department of Local Government, Industry Regulation and Safety since July 2025, handles the administration and the public licence search. There are two numbers to know. An electrical contractor's licence, starting with EC, is what lets a business carry on electrical contracting; an electrician's licence, starting with EW, belongs to the person doing the work, and a contractor's licence depends on the holder, or a nominee they employ, holding an electrician's licence. The advertising rule is about the EC number: regulation 45(1) of the Electricity (Licensing) Regulations 1991 says it must be conspicuously displayed in any advertisement for the contracting business.
Building and Energy's guideline on licence numbers in advertising lists web pages alongside business cards, vehicle signs and directory entries. The number is the EC prefix and six digits, though leading zeros can be left off and a short label such as Lic. No. in front is fine. The guideline asks for the number to sit with the main body of the ad rather than somewhere unrelated, and gives a rule of thumb of at least half the size of the largest lettering. It also says not to mention Western Power or Building and Energy next to the number, because the Electrical Licensing Board issues the licence. On a website, we read that as your EC number at the top of every page at a size people notice, not grey small print at the bottom.
Two pieces of paperwork follow most jobs. For notifiable work, the contractor sends a notice of completion to the network operator within 3 days of finishing, and across the Perth metropolitan area that operator is Western Power, whose network stretches north to Kalbarri, east to Kalgoorlie and south to Albany. For most installing work, maintenance aside, the customer must receive an electrical safety certificate within 28 days. The state's consumer advice tells anyone who doesn't get one to ask the contractor first and then the network operator, so a line on your site saying you issue it is a small reassurance that answers a real question.
Property work has rules of its own. A home being sold must have RCDs protecting every circuit that supplies power points and lights before the title transfers, with two as the minimum; a rental needs two on the switchboard before it's leased, and a short-term rental before guests stay. Homes also need compliant mains-powered smoke alarms, less than 10 years old, before a sale, tenancy or hire. RCDs must be installed by a licensed electrical contractor, so an agent or landlord facing a sale or a new lease has to find one.
The metropolitan region spans 30 local government areas, from Wanneroo and Joondalup in the north to Rockingham and Kwinana in the south and Mundaring and Kalamunda in the hills, and locals often describe home as north or south of the river. Few electricians cover all of it for every kind of job, so the site should say where you'll go and for what. We're an Adelaide team working with Perth businesses by phone and email, and we haven't built for a WA electrician, or any WA business, yet.
