There’s a version of this article that’s all jokes about getting zapped. We’ve written enough of those. Here’s the version that’s actually useful: what the law says, what your insurer says, and where the line sits between sensible self-reliance and a genuinely bad idea.
What you can legally do yourself in Victoria
Shorter list than most people expect.
You can: replace a light globe, replace a fuse wire in an old-style ceramic fuse carrier, reset a tripped circuit breaker or RCD, plug in and unplug appliances, and replace a plug-in appliance’s own flexible cord if you’re competent — though even that is contested and we’d rather you didn’t.
You cannot: install or replace a power point, install or replace a light fitting or switch, install a ceiling fan, run new cable, alter a circuit, work on the switchboard, connect an appliance to fixed wiring, or do anything at all inside a wall cavity.
The dividing line is essentially: anything connected to the fixed wiring of the building is licensed work. If it’s hardwired, it’s not yours.
This is set by the Electricity Safety Act 1998 and enforced by Energy Safe Victoria. It’s not a guild protecting its patch — it’s the same principle that stops people plumbing their own gas.
The three reasons it isn’t worth it
1. Your insurance
This is the one that gets people, and it gets them at the worst possible moment.
Most home and contents policies contain a condition requiring that work on the property be carried out by appropriately licensed tradespeople. If unlicensed electrical work contributes to a fire, a flood from a damaged pipe, or an injury, the insurer has grounds to decline the claim.
Note what that means in practice. It isn’t just that they won’t pay for the faulty power point. If that power point starts a fire that takes the house, the whole claim is in question.
You are risking a seven-figure asset to save a few hundred dollars. There’s no version of that arithmetic that works.
2. The legal exposure
Energy Safe Victoria issues substantial penalties for unlicensed electrical work, and they do enforce it.
Beyond fines: if unlicensed work you did causes injury or death to someone else — a family member, a tenant, a future owner — you’re into criminal liability, not just a fine.
And if you’re a landlord, you have specific statutory obligations around electrical safety in rental properties. DIY work in a rental is a category of bad idea all its own.
3. Selling the house
Undocumented electrical work turns up during conveyancing more often than people expect. Buyers’ inspectors look at switchboards. Purchasers ask for Certificates of Electrical Safety.
Every piece of licensed work generates a certificate. DIY work generates nothing — and a house with obvious non-compliant work either loses the sale or gets remediated at your cost, at the least convenient moment possible.
What actually goes wrong
The failures we’re called to fix have patterns, and it’s rarely a dramatic explosion.
Loose terminations. Getting a connection mostly tight is the most common DIY error. A loose terminal arcs, arcing generates heat, and heat degrades everything around it over months or years. This is a leading cause of electrical fires and it’s completely invisible from the room.
Wrong cable size. Cable is sized to the circuit’s protection, not to what feels chunky enough. Undersized cable overheats before the breaker trips, which defeats the purpose of the breaker.
No earth, or a compromised earth. The earth does nothing at all until the moment it’s the only thing standing between someone and a fault current.
Ceiling fans mounted to plasterboard or a batten. Several kilograms of rotating mass above a bed. We’ve taken down fans that were working themselves loose.
Downlights hard against insulation. A specific and well-documented fire risk, and one of the most common things we find in roof spaces.
Circuits extended off lighting. Someone runs a new power point off a light point because the cable was handy. Now there’s a 10A load on a circuit protected for lighting.
Bathroom and outdoor work in the wrong zone. Zone requirements exist because water and electricity have a specific and well-understood relationship.

What “licensed” actually means
Worth understanding, because the terms get used loosely.
A licensed electrician has completed a four-year apprenticeship and holds a current Electrician’s Licence (A-Grade). They can do the work.
A Registered Electrical Contractor (REC) is licensed to contract for electrical work and to issue Certificates of Electrical Safety. This is what you want on your invoice. Ours is REC 25989 — it’s verifiable, and you should verify it.
A Registered Master Electrician has additionally met the standards of Master Electricians Australia, an independent industry body. It isn’t compulsory. It does mean someone external has looked at how the business operates.
The Certificate of Electrical Safety is the document that proves the work was done compliantly. Keep every one you’re given. You’ll want them when you sell, and your insurer will want them if anything ever happens.
If someone quoting you can’t produce an REC number, that’s the end of the conversation.
The honest cost comparison
The reason people attempt this is cost, so let’s be straight about it.
Most of the jobs homeowners are tempted to do themselves — adding a power point, replacing a light fitting or fan, fixing a dead outlet — are small jobs. The saving is real but modest.
What you’re buying for that difference: work that meets AS/NZS 3000, a certificate, valid insurance, someone who carries public liability, and in our case a lifetime workmanship warranty — if something we install ever fails, we come back and fix it, with no time limit.
It’s also worth batching. If we’re already at your place, adding three more power points costs far less than three separate visits. Most people underestimate how much of a small job’s cost is simply getting someone there.
