Updating old, yellowed, or faulty light switches is one of the easiest ways to modernise a room. While it seems like a simple job, it must be done by a professional to ensure your home remains safe.
On average, for a standard like-for-like replacement, you can expect to pay between $90 and $150 (inc. GST) for the first switch. This is a typical service-and-supply fee, covering the electrician’s call-out, labour, and the new switch.
Quick Price Guide: Cost per Light Switch
| Scenario | Estimated Cost (Inc. GST) | What’s Included |
|---|---|---|
| Single Standard Switch (Like-for-like) | $90 – $150 | Call-out, labour, basic toggle or rocker switch. |
| Multiple Standard Switches (e.g., 3+ switches) | $60 – $100 each | Reduced per-switch cost as the initial call-out is covered. |
| Dimmer Switch Installation | $120 – $200+ each | Supply & installation of a standard dimmer module. |
| Smart Switch / Wi-Fi Switch | $180 – $280+ each | Supply, installation, and configuration with your app. |
| Double or Triple Gang Plate | $130 – $190+ each | Replacing a single switch with a 2 or 3-gang unit. |
What Factors Influence the Final Cost?
Several variables can cause the price to change:
-
Type of Switch: A basic switch is inexpensive. Dimmer switches and smart switches (like Wi-Fi or Zigbee models) have a significantly higher parts cost and often take longer to install and configure.
-
Number of Gangs: Replacing a single switch (1-gang) is straightforward. Upgrading a plate to fit two or three switches (2-gang or 3-gang) requires more labour and a new, larger mounting plate.
-
Switch Location & Accessibility: Is the switch behind furniture? Is it on a solid brick or tiled wall? Difficult access can add time to the job.
-
Wiring Condition: When the electrician removes the old switch, if they find outdated, damaged, or unsafe wiring (like old rubber insulation), they are legally obligated to rectify it. This adds to the cost but is crucial for safety.
-
The Electrician’s Expertise: A licensed sole trader may have slightly lower rates than a larger, insured company with master electricians, though both are qualified.
Why is there a Minimum Charge?
The minimum fee (often for 1 hour of labour) covers the electrician’s travel, vehicle costs, and the first portion of labour. This is why replacing several switches at once is the most cost-effective approach.
Why You Must Use a Licensed Electrician
Replacing a light switch is not a DIY job. In Australia, it is illegal and extremely dangerous for an unlicensed person to perform any electrical work.
A licensed electrician ensures:
-
Safety: Prevents risks of electric shock, short circuits, and house fires.
-
Compliance: All work is certified and meets the Australian Wiring Standards (AS/NZS 3000).
-
Insurance: Your home insurance will be void if an electrical fault caused by unlicensed work results in damage.
Getting the Best Value
-
Bundle Your Jobs: The most effective way to save is to replace all outdated switches in your home during a single service call.
-
Choose Your Switches: Decide if you want standard, dimmer, or smart switches beforehand. Your electrician can often supply these for you.
-
Get a Confirmed Quote: A reputable electrician will provide a clear verbal estimate over the phone for a standard swap and confirm the price on site before starting any work.
