Electricians near you

This is the single most important thing for a homeowner in Australia to understand, because it differs from the rules many people grew up with elsewhere. Queensland's position is that a person who performs electrical work in Queensland must have an electrical work licence authorising that work, and the examples the regulator gives are deliberately small: installing a light switch or a power point, replacing a light fitting with a ceiling fan, repairing electrical equipment, even replacing the plug on the end of an extension lead. Only a licensed electrician can install a safety switch. Substantial penalties apply, and they escalate sharply where the breach exposes someone to a risk of death or serious injury.

New South Wales takes the same approach from the licensing side: you need an electrical licence or certificate before you can do any electrical wiring work, regardless of the cost of the work and regardless of whether the property is residential, commercial or industrial, and by law the work must be done by or under the supervision of a licensed electrician. Significant fines apply to unlicensed work for individuals and larger ones for companies.

Victoria adds a structural requirement on top. An electrician must work for a Registered Electrical Contractor to carry out work for a customer, so a homeowner engaging someone privately should be engaging a REC. Energy Safe Victoria's advice is to always ask to see a tradesperson's licence, and it publishes a public register you can search. Beyond the legal risk, unlicensed electrical work commonly voids home and contents insurance, which turns a small saving into an uninsured loss.

In Victoria, a Certificate of Electrical Safety is a legal document issued by a Registered Electrical Contractor or licensed electrical worker recording the details of the work performed, with copies delivered to the customer, to Energy Safe and to other required parties. Unregistered and unlicensed people cannot purchase or lodge these certificates at all, which is precisely why the certificate is useful evidence for you. Victoria also splits work into prescribed and non-prescribed categories: prescribed work, such as consumer mains, the main switchboard, the meter box, the main earthing system and renewable energy systems, requires independent inspection and cannot be energised until it is inspected. Non-prescribed work such as lights, power points and air conditioning is energised on completion.

In New South Wales, electricians must submit a Certificate of Compliance for Electrical Work to demonstrate compliance and that safety inspections have taken place, with penalties for non-compliance or unsafe installations.

In Western Australia, an electrical contractor carrying out notifiable electrical installing work must lodge a notice of completion with the relevant network operator, or with Building and Energy where there is no network operator, and deliver an electrical safety certificate. The person signing is responsible for ensuring the work is complete, safe and compliant with the regulations and relevant technical standards including AS/NZS 3000:2018, and the contractor must retain the notice and the associated testing and checking records for at least five years.

Residual current devices, known in Australia as safety switches, cut the supply within milliseconds when they detect current leaking to earth, and regulators describe them as the single most effective measure to prevent electrocution, serious electrical injury and electrical fire. They are not the same thing as circuit breakers or fuses, which protect the wiring from overload rather than protecting people.

Under the Wiring Rules, additional protection by RCDs with a maximum rated residual current of 30 mA is required for final subcircuits in domestic and residential electrical installations, and Western Australia's requirement for homes is a minimum of two safety switches, with more needed in many installations. Following the update to AS/NZS 3000:2018, Type AC RCDs are no longer permitted to be installed in Australia, because they do not adequately detect the pulsating DC fault currents that modern electronics, inverters and EV chargers can produce.

Testing is the part a homeowner can and should do. Press the test button on each safety switch periodically; the switch should trip immediately, and you then reset it. A safety switch that does not trip when tested, or that will not stay reset, is a fault for a licensed electrician. Installing or replacing one is never homeowner work.

Every state publishes a licence register, and checking takes a minute. New South Wales has a licence verification service, Victoria has Energy Safe's public register of licensed electrical workers and Registered Electrical Contractors, Queensland and Western Australia publish their own searches. Ask for the licence number rather than accepting a photo of a card, and check that the licence class actually covers the work you want done.

If the work is defective, the Australian Consumer Law's consumer guarantees apply: services must be carried out with an acceptable level of care and skill, and a business must fix a minor problem with at least a free repair. Because electrical work is safety-critical, you also have a regulator to go to. The certificate issued for the work identifies who did it, which is exactly what a complaint to the state electrical regulator needs. That is another reason to insist on receiving your copy at completion rather than chasing it months later.
