Certificate of Electrical Safety in Victoria: A Homeowner’s Guide
Understand when Victorian electrical work needs a Certificate of Electrical Safety, who issues it, and what homeowners should retain after the job.
Quick answer
In Victoria, electrical installation work must be completed through the licensed electrical-safety system. A Certificate of Electrical Safety records the work and makes the electrical worker accountable for what was completed.
What the certificate tells you
A Certificate of Electrical Safety, usually shortened to COES, is the formal record for electrical installation work carried out in Victoria. It is not a marketing certificate or an optional warranty. Energy Safe Victoria describes it as a legal document that makes the electrician accountable for the work completed.
The certificate identifies the responsible electrical worker or contractor, the property, the type of work and the date. Keep your copy with renovation records, appliance documents and property files. It may be useful when work is reviewed later, when a home changes hands or when another electrician needs to understand previous alterations.
Prescribed and non-prescribed work
Victoria separates electrical installation work into prescribed and non-prescribed categories. Prescribed work includes higher-risk parts of an installation such as consumer mains, a main switchboard, a meter box and the main earthing system. It requires an independent inspection before the certificate is finalised.
Non-prescribed work includes many common residential jobs such as lights and power points. It does not require the same independent inspection step, but it still requires a certificate. The classification depends on the actual scope, so the electrician—not the homeowner—should determine the correct certificate process.
What to ask before accepting a quote
A useful quote should define the intended electrical scope and explain whether access, testing or an independent inspection may affect the booking. You do not need to diagnose the certificate category yourself, but you can ask how the completed work will be documented.
- Is the person or business authorised to undertake the proposed work in Victoria?
- Does the quote identify the fittings, circuits or switchboard work included?
- Will an independent inspection be required before power can be restored?
- When and how will your certificate copy be provided?
- Are certificate or inspection administration charges included in the quote?
Why records matter for future electrical work
Electrical installations change over time. A new circuit today may support an appliance upgrade later; a switchboard replacement may affect future solar, battery or renovation planning. Clear records help the next electrician understand what was altered and reduce reliance on assumptions.
A certificate does not replace a property-specific inspection and it does not mean every unrelated part of the home has been assessed. It records the installation work described on that certificate. If you are buying an older property or planning a major renovation, ask separately what inspection or testing is appropriate for the broader installation.
