Replacing a power point in Australia: cost, process, and why a sparky is mandatory

A cracked power point, a brown stain around an outlet, a USB upgrade, every one of these is a licensed electrician job in Australia. This article explains what the work involves and what to expect on the quote.

Why this is licensed-only work

Replacing a power point requires:

• Disconnecting active, neutral, and earth wires under live conditions (or at least conductors that could become live)
• Testing the circuit’s continuity, polarity, and earth integrity
• Issuing a Certificate of Compliance in NSW, VIC, QLD

There is no DIY-permitted version of this work in any Australian state. The work itself looks deceptively simple, there are videos online showing the steps, but the risks (electrocution, fire, insurance void, criminal penalty) make the $90 sparky call-out the only sensible option.

What the sparky does

1. Identify the circuit at the switchboard and isolate it
2. Verify isolation at the outlet with a tester
3. Remove the existing faceplate and back-box mechanism
4. Inspect the wiring, insulation condition, conductor size, terminals
5. Fit the new mechanism (or new fitting if changing single/double)
6. Test polarity, earth continuity, and operation under load
7. Issue a Certificate of Compliance where required

A straightforward swap takes 20–40 minutes. The bulk of the cost is the call-out, not the work itself, so it’s economical to bundle multiple outlets into one visit.

2026 cost ranges

Scenario	Sparky cost (AUD)
Single GPO replacement	$90–$180
Double GPO replacement	$100–$200
GPO with USB-A or USB-C points	$130–$240
Single → double upgrade (same back-box)	$130–$220
Double → quad (new back-box required)	$200–$400
New GPO where none existed (run cable)	$250–$600
Bulk replacement (5+ outlets in one visit)	$50–$100 per outlet after the first
After-hours / emergency	Add 50–100%

Plus the fitting itself: $5–$15 for basic single, $15–$25 for double, $30–$60 for USB integrated.

Signs your power point needs urgent replacement

Call a sparky immediately if:

• Brown or black stains around the faceplate, heat damage from a loose connection
• The faceplate is warm to touch, electrical resistance is generating heat
• The plug falls out when you let go, worn internal contacts, fire risk
• Cracked faceplate exposing terminals, shock hazard, especially with children
• A burning smell, turn off the circuit at the switchboard immediately and call

These are the precursors to electrical fires. The $150 you save by ignoring them turns into $30,000+ when the wall starts burning.

Choosing a power point

The fitting specs that matter:

• Rating, standard Aussie GPO is 10A, 240V. Higher-current appliances (some air-cons, oven circuits) use 15A or 20A points with different blade configurations.
• USB type. USB-A is being phased out. USB-C is the new standard. Quick-charge points (45W+) cost more.
• Surge-protected, some premium GPOs include MOV-based surge suppression at the outlet. Useful for AV cabinets.
• Australian-approved, look for the RCM tick (regulatory compliance mark). Imported off-brand outlets sometimes lack certification, a sparky may refuse to install non-RCM products.

Power point replacement is a $90–$200 job in business hours, takes well under an hour per outlet, and is one of the most affordable electrical safety upgrades you can make. If yours shows any sign of heat damage, replace it now, not after the wall catches fire.
