Australia takes electrical licensing more seriously than almost any other country: there is no legal DIY category for fixed wiring here, unlike the partial allowances in the US or New Zealand. That is not bureaucratic excess. Electricity is the rare household hazard that kills silently and burns houses down years after the bad work was done.
This guide covers what the law actually says, how to verify a licence in under a minute, the paperwork you should receive, and the warning signs that should end a conversation before any work starts.
Why DIY electrical work is illegal
In every Australian state and territory, electrical work on fixed wiring, which includes replacing a light switch, adding a power point, or altering anything wired into the walls, may only be performed by a licensed electrician. Plugging in appliances and changing light globes is fine; anything with a screwdriver near fixed wiring is not.
The consequences run beyond fines. Unlicensed work can void your home insurance, complicates the sale of the property, and leaves faults that a purchaser's inspection or a later tradesperson must legally report. Most seriously, DIY wiring errors kill people, sometimes the person who did the work, sometimes a family member years later, sometimes the next owner. The licensing regime exists because the failure mode is invisible until it is lethal.
Verifying the licence: one minute, every time
Every state runs a free public register. Ask for the licence number before booking, then check that the licence is current, the name matches the person or business quoting, and the class covers the work being done.
In South Australia the register sits with Consumer and Business Services. Victoria's electrical licensing is handled by the state's energy safety regulator. In NSW it is Fair Trading's licence check, and in Queensland the electrical safety office maintains the register. The other states and territories have equivalents, all searchable online. A legitimate electrician gives the number without hesitation; reluctance is itself the answer.
The certificate of compliance
After completing electrical work, the electrician must certify it, and for most work you should receive a certificate of compliance (the exact name and form varies by state). It confirms the work was done by a licensed person, tested, and compliant with the wiring rules.
Keep every certificate with your house documents. They are your evidence for insurance claims, warranty disputes and the eventual sale of the property. Ask before the job starts whether the work generates a certificate and when you will receive it. An electrician who is evasive about compliance paperwork is describing their standards for you.
Red flags worth acting on
None of these alone proves a problem. A pattern of them tells you what you need to know:
- No licence number offered, or one that does not match the state register
- Cash-only pricing, or a discount for skipping the certificate
- Verbal quotes only, or written quotes with one line and no breakdown
- Large upfront payment demanded before materials are ordered
- Urgent extra faults discovered mid-job with no photos or evidence shown
- Dismissiveness about safety switches, testing or compliance paperwork
- No physical business presence and reviews mentioning unfinished work
Comparing quotes properly
Collect two or three written quotes for anything beyond a small job, itemised into labour, materials, callout and GST. Confirm whether each is a fixed price or an estimate, what happens if scope grows, and that certification is included.
Then normalise the scope before comparing numbers. One quote might include patching plaster and disposing of old fittings; another silently excludes both. As a sense check, typical rates run $80 to $130 per hour with callouts of $70 to $130, so a quote wildly below the pack is missing something rather than being generous. How each electrician answers your questions is data too: the one who explains trade-offs clearly on the phone tends to be the one whose work passes inspection.
Insurance and warranties
A professional electrician carries public liability insurance and will confirm it when asked. On top of that, Australian Consumer Law guarantees services are performed with due care and skill, and materials carry manufacturer warranties, often five years or more on quality fittings.
If something fails after the job, go back to the electrician first with your invoice and certificate. Licensed trades have every incentive to fix defects quietly, because complaints to the state regulator attach to the licence they cannot work without. That leverage is exactly what you gave up if you hired someone unlicensed.
Frequently asked questions
What electrical work can I legally do myself in Australia?+
Very little: changing light globes, replacing fuse wire in an old-style fuse holder, and plugging in appliances. Replacing switches, outlets, light fittings or anything involving fixed wiring requires a licensed electrician in every state and territory.
How do I check if an electrician is licensed?+
Ask for the licence number and search the free public register in your state: Consumer and Business Services in SA, the energy safety regulator in Victoria, Fair Trading in NSW, the electrical safety office in Queensland, and equivalents elsewhere. Confirm the licence is current and the name matches the quote.
What paperwork should I get after electrical work?+
An itemised invoice and, for most work, a certificate of compliance confirming the work was performed by a licensed person and tested against the wiring rules. Keep both with your house records; insurers and future buyers may ask for them.
What if I discover unlicensed electrical work in my home?+
Have a licensed electrician inspect and report on it, and rectify anything unsafe promptly. If you know who did the work, your state electrical regulator takes reports of unlicensed work. If you are buying a property, unexplained amateur wiring is a legitimate reason to renegotiate or walk away.
