Commercial electricians specialise in three-phase power systems, higher-capacity switchboards, and complex wiring layouts found in offices, shops, warehouses, and industrial sites. They also handle commercial compliance requirements including emergency exit lighting, RCD testing schedules, and test-and-tag obligations under Australian workplace safety laws.
Overview
Australian businesses have electrical needs that go beyond residential work — three-phase machinery, commercial-grade lighting, data cabling, emergency and exit lighting, and compliance with Work Health and Safety (WHS) regulations. A licensed commercial electrician understands the specific codes, load calculations, and safety obligations that apply to workplaces. From fitting out a new office to maintaining a retail chain's electrical infrastructure, commercial electricians keep your business running safely and legally.

How much does it cost?
Commercial electrician rates in Australia range from $90 to $150 per hour, reflecting the higher complexity and compliance requirements of commercial work. Full office fit-outs can range from $5,000 to $50,000 or more depending on size and scope. Three-phase switchboard upgrades typically cost $3,000 to $8,000. Emergency and exit lighting installation runs $150 to $400 per unit. Most commercial electricians provide detailed project-based quotes rather than hourly billing for larger jobs.
Australian regulations
Commercial electrical work in Australia must comply with AS/NZS 3000 (Wiring Rules), AS/NZS 3760 (In-service safety inspection and testing), and relevant Work Health and Safety (WHS) legislation. Emergency and exit lighting must meet AS 2293, and testing is required every six months. Portable appliance test-and-tag is mandatory in many workplaces under state WHS codes of practice. All commercial electrical work requires certification, and records must be retained for auditing purposes.
