Electrical work you cannot do yourself

What needs an electrician, and what does not

Queensland's Electrical Safety Office publishes both sides of the line, which is more than most regulators do. The lists are theirs, not ours; the principle travels.

Two of those catch almost everybody. Repairing an appliance is electrical work, and so is putting a new plug on an extension lead — the two jobs a handy person is most likely to think of as obviously fine. And the right-hand column comes with its own warning from the same page: cutting holes or driving screws into walls still risks contact with wiring inside the cavity.

Where the line actually sits: the outlet socket

New South Wales draws it in law, and once you see it you can apply it anywhere. Electrical wiring work is “the actual physical work of installing, repairing, altering, removing, or adding to an electrical installation” — and an electrical installation expressly does not include “any electrical article connected to, and extending or situated beyond, any electrical outlet socket”.

So: the socket is the border. On your side of it — the toaster, the lamp, the extension lead you bought finished, the plug you push in — is yours. On the other side of it, and everything fixed into the building, is a licensed electrician's. The same NSW definition also carves out equipment operating at no more than 50 volts AC or 120 volts ripple-free DC, which is why low-voltage garden lighting is a different conversation from a garden power point.

Every state and territory says the same thing

Each row was read at that regulator on the date shown. The wording is theirs.

Victoria carries no dollar figure here on purpose: its penalties are expressed in penalty units whose value changes each financial year, and a stale conversion would be worse than no number. The same goes for the ACT's 50 penalty units.

Why the rule has no small-job exception

Every state that writes a dollar figure into a building rule declines to write one into this one. New South Wales says the words: a licence is required “regardless of the cost of the work”. There is no under-$X carve-out, no small-job exception, and no version of it for a mate doing you a favour.

The reason is not bureaucratic. Building work is regulated on what the job is worth. Electrical work is regulated on what it can do to you — and a bad connection behind a wall does not become safer because the invoice was small.

What actually happens when people get caught

Queensland publishes its prosecutions, so you do not have to take the maximums on faith. Two real cases, both from the Office of the Work Health and Safety Prosecutor.

A landlord changed one light switch. His tenant reported a broken switch at a Brisbane rental in December 2019, and the owner swapped it himself rather than pay an electrician, then told the tenant it was safe. The Electrical Safety Office inspector who examined it found an earth wire had been used as a switch wire, and disconnected the circuit. One switch. He was fined $400 plus costs in 2020, the maximum for that offence is $4,000, and the dangerous part is that he genuinely believed he had done it properly.

A fourth-year apprentice sold electrical work on Airtasker. Over about six weeks in late 2020 he did jobs for 27 customers, the court report (2023) lists ceiling fans, power points, lights and cooktops, sold while he promoted himself as a licensed contractor. Four of the jobs broke the Wiring Rules badly enough to create a risk of electric shock or fire. He was fined $45,000 across six offences. And he was a year off being qualified, which is the answer to whether a handyman or a mate who is “basically an electrician” can do it. No licence, no electrical work.

Your insurer is the other reason

Queensland's Electrical Safety Office says it in a single sentence: major property damage from an electrical fire is a real risk, and “if it was the result of illegal electrical work, your insurer may refuse the claim.” South Australia says the same: insurers may not cover fire or injury caused by do-it-yourself electrical work.

The danger is also not usually visible on the day — the same Queensland page notes it “may not be immediately apparent and often only becomes evident in a fault situation, or may even develop over time.” Work done badly in 2026 can sit quietly behind a wall until 2032.

There is a related consequence when a licensed person does it instead. Queensland requires licensed electrical contractors to carry a minimum of $5 million public liability insurance with a $50,000 consumer protection component. Unlicensed work, as the regulator puts it, “does not provide this assurance or protection.”

The paperwork you should be handed when it is finished

Most states require the electrician to give you a certificate for the work, and it is the document that proves the work was done properly. Ask for it before the job, not after.

• Victoria — a Certificate of Electrical Safety for any electrical installation work. Major wiring work (where the power cannot be switched off) must also be inspected by a qualified inspector, arranged by your contractor.
• Western Australia — “your electrical contractor must give you an electrical safety certificate within 28 days” (excluding maintenance and like-for-like replacement).
• South Australia — an electronic certificate of compliance (eCoC) within 30 days for most electrical work; not for minor maintenance such as replacing globes.
• Northern Territory — licensed electrical contractors issue the certificate of compliance, “your warranty that electrical work is performed to the relevant standard and is safe”.
• Elsewhere — ask your state's electrical regulator what paperwork you are owed. Our licence-check page lists every regulator.

This page explains what electrical safety regulators publish about unlicensed work. It is general information, not legal advice, and it is not a safety assessment of anything you are planning. Yamate is not an electrical regulator, does not issue, assess, endorse or certify any licence, and does not decide what is or is not electrical work — your state's electrical regulator does. No regulator has reviewed this page. Every rule and penalty above was read at the regulator's own page on the date beside it and is linked beside the claim. Penalties and definitions change, so check the date on this page against theirs. If you think something in your home is unsafe, stop and call a licensed electrician.
