Whether you’re upgrading the look of your home or need to fix a faulty light, replacing a light fitting is one of the most common electrical jobs for homeowners. But before you grab a ladder and a screwdriver, it’s worth knowing what’s involved — and what’s best left to a licensed electrician.
At JayCab Electrical, we’re often called out for light fitting replacements across Castle Hill and surrounds. Here’s what you need to know before getting started.
Can I replace a light fitting myself?
Short answer: not legally in Australia unless you’re a licensed electrician.
In Sydney and throughout Australia, replacing a light fitting is considered electrical work. That means DIY isn’t just risky – it’s also illegal. Even something that seems simple, like swapping out a ceiling light, carries a risk of electric shock, fire, or damaging your home’s wiring.
The safest and legal option? Call a licensed electrician.
How much does it cost to replace a light fitting?
The cost can vary depending on a few factors, including:
The type of light fitting (e.g., downlight, pendant, oyster)
Accessibility (high ceilings or difficult-to-reach places)
Whether it's a straight swap or needs rewiring
On average, you can expect to pay $80–$150 per light fitting for a basic replacement. More complex fittings or installations with multiple lights may cost more.
At JayCab Electrical, we offer transparent pricing and can give you a firm quote upfront – no surprises.
How to replace a light fitting
Wondering how to replace a light fitting safely? Here’s how a licensed electrician does it:
1. Power Off: Electricity is shut off at the switchboard.
2. Remove Old Fitting: The existing fitting is carefully detached, checking for any damage or wear.
3. Check Wiring: We inspect and test the wiring to ensure it’s up to code.
4. Install New Fitting: The new fitting is wired and mounted securely.
5. Test & Clean Up: We test the light, ensure it works properly, and clean the area.
It’s quick, clean and safe – when done by a licensed electrician.
How do you change a light fitting if it's a bayonet?
A bayonet light fitting replacement is common in older homes. These fittings have a twist-lock mechanism and can wear out or break over time.
If you’re wondering how to replace a broken bayonet light fitting, the process involves:
Disconnecting power at the mains
Removing the bayonet fitting and inspecting wiring
Installing a modern fitting, often switching to an Edison screw or LED-compatible base
Modern upgrades can improve energy efficiency and reduce future maintenance. We can help you choose the right fitting and ensure it’s safely installed.
Is it worth upgrading my light fittings?
Absolutely. Replacing outdated or faulty light fittings can:
Improve lighting quality and energy efficiency
Modernise the look of your home
Reduce the risk of electrical faults
Whether you’re fitting a light in a new build or replacing old bayonets, updating your lighting can add real value to your home.
