If you’ve ever had electrical work done in Australia and the electrician handed you a piece of paper at the end, you’ve probably been given a Certificate of Electrical Safety. Most customers file it without reading it, or worse, never receive it because nobody mentioned it should have been issued. The certificate is a legal record that the electrical work was done by a licensed person, tested to the relevant standard, and is safe to use. It also matters for your insurance, your future property sale, and your warranty rights. It is not just paperwork.
Here’s what a Certificate of Electrical Safety actually proves, what it doesn’t, and what to do if you didn’t receive one for work that should have come with one.
What the certificate actually says
A Certificate of Electrical Safety, often called a CES or Certificate of Compliance for Electrical Work, is the licensed electrical worker’s formal declaration that the electrical work performed at a property complies with the relevant legislation, the AS/NZS 3000 wiring rules, and any other applicable standards. It identifies the licensed worker, the licensed contractor, the property where the work was done, the scope of the work, the date of completion, and the test results that confirm the installation is safe to energise. It is a legal document, not a marketing leaflet.
It is required for almost all licensable electrical work
In most Australian states, a CES or equivalent must be issued for any electrical work that requires a licensed electrician. That includes new wiring, additions to existing circuits, switchboard upgrades, hot water connection changes, oven and cooktop hardwired installs, EV charger installs, and most renovation electrical work. Like-for-like replacement of a fitting that doesn’t change the underlying circuit may have lighter requirements in some states. The default assumption: if the electrician needed a licence to do it, a certificate should be issued.
It proves the work was tested, not just done
A common misconception is that the certificate just confirms an electrician did the work. It proves more than that. The licensed worker is required to perform a defined sequence of tests on the installation before issuing the certificate, including continuity, polarity, insulation resistance, earth fault loop impedance and RCD operation. The certificate’s value comes from those tests being carried out and the results being recorded. An installation that wasn’t properly tested cannot honestly carry a compliance certificate, regardless of how confident the electrician is in their work.
Why it matters for insurance
Home and contents insurers care deeply about whether electrical work was done by a licensed electrician with a compliance certificate. After a fire or a serious electrical fault, the insurer typically asks for evidence that any recent electrical work was certified. If you can’t produce a CES for relevant work, the insurer may reduce or decline a claim, particularly if the work is implicated in the cause. Filing the certificate alongside your insurance papers is one of the cheapest forms of insurance protection a customer has.
Why it matters for selling the property
When a property is sold, the buyer’s conveyancer or building inspector commonly asks for compliance certificates for any electrical or plumbing work done during the seller’s ownership. Missing certificates can complicate settlement. The buyer may ask for a price reduction, or insist on retesting and certification at the seller’s cost before completion. Keeping the certificate filed is much cheaper than reconstructing the paperwork years later, particularly if the original electrician has left the trade or the licence has lapsed.
What it doesn’t prove
A compliance certificate doesn’t prove the workmanship was first-rate. It proves the work meets the legal minimum: the standards, the tests, the safety thresholds. Compliance is the floor, not the ceiling. A certificate also doesn’t prove the work matches the customer’s commercial expectations: the cable run might be untidy, the GPO position might be inconvenient, the conduit might be visible where the customer expected concealed. These aren’t compliance issues, they are workmanship and contract issues. Different complaint, different remedy.
Where the certificate goes
The licensed worker is generally required to provide a copy of the certificate to the customer, the contractor, and in some states to the relevant electrical safety regulator. In Victoria, electrical contractors must lodge a CES through Energy Safe Victoria’s portal for prescribed work. In Queensland, the Electrical Safety Office receives lodgements. In NSW, the Department of Fair Trading and the network operator may require notification for some work. The customer’s job is to receive their copy and store it somewhere it can be found.
What to do if you didn’t receive one
If electrical work was done at your property and no certificate was provided, the first step is to ask the contractor in writing for the certificate, identifying the work and the date. Most legitimate operators will produce one quickly because they have to issue it anyway. If the contractor refuses, the certificate doesn’t exist, or the work was done by an unlicensed person, lodge a complaint with the relevant electrical safety regulator. The regulator can compel a licensed contractor to produce the document, and can take action where the work was unlicensed.
When the certificate identifies a problem
Sometimes the testing required for a CES uncovers a pre-existing fault on a property’s electrical installation. The contractor may be obliged to disclose the fault and may not be able to issue a clean certificate without remedial work being done. If that happens, ask for a clear written explanation of what was found, what was already there before the new work started, and what is required to bring the installation to compliance. The customer should not be charged for fixing a pre-existing problem under the original quote, but is generally responsible for paying to make their installation safe.
A Certificate of Electrical Safety is one of the most under-appreciated pieces of paper in the average Australian home. It proves the work was licensed, tested and compliant with the wiring rules. It protects you in an insurance claim, in a sale, and in any later dispute. Ask for it before the electrician leaves. Save it with your house papers. The five minutes you spend filing it could save you tens of thousands later.
