A certificate of test is the document a licensed electrician gives you after completing electrical work, confirming the work has been tested and complies with the Australian wiring rules. In Queensland it is not a courtesy, it is a requirement. If you have paid for electrical work and never received one, this article explains what the certificate covers, when you should get one, and why it matters more than most homeowners realise.
What a certificate of test actually confirms
Before any new electrical work is put into service, the electrician must test it. That includes checks like earth continuity, insulation resistance, polarity and correct circuit connections. The certificate records that this testing was done and that the installation complies with the wiring standard, AS/NZS 3000. It identifies the work performed, the property, the licensed contractor and the date.
In short, it is your written evidence that the work was completed by a licensed electrician and tested as safe. For details on electrical licensing and safety requirements in Queensland, see WorkSafe Queensland.
When you should receive one
Any notifiable electrical work should come with certification. Common examples for Brisbane homeowners include a switchboard upgrade, new circuits or power points, a rewire, an oven or cooktop connection, and solar or battery installations. Routine like-for-like repairs are still tested, and a professional electrician will provide certification for those as well.

Why the certificate matters
Three situations make this piece of paper valuable.
Insurance. After an electrical fault or fire, insurers ask who did the work. A certificate of test shows the work was performed and tested by a licensed contractor.
Selling your home. Buyers and building inspectors increasingly ask for evidence of electrical work. Certificates for switchboard upgrades, rewires and solar installations support your sale rather than raising questions.
Safety disputes. If something goes wrong with recent work, the certificate identifies exactly who is responsible for it. Without one, proving who did what becomes difficult, especially if the work was done cheaply and off the books.
What to do if you never got one
First, ask the electrician or contractor who did the work. They are required to keep records and should be able to provide certification. If they cannot or will not, that is a warning sign about the quality of the work itself. In that case it is worth booking an electrical safety inspection so a licensed electrician can test the installation and tell you exactly where it stands.
If you are ever unsure whether work at your place was done properly, or you have bought a home with a history of DIY wiring, we can inspect, test and certify what is there. Call 07 3060 9105.
