Flickering Lights in Your Annandale Home
A light that flickers, dims or misbehaves in a pattern you can't quite explain is one of the questions we're asked about most.
This page walks through what's actually behind it and when it's genuinely worth concern. Ring (02) 9538 7444 if it's happening in your home today.
Flickering Lights, Explained in Plain English
A light needs a steady, consistent supply of current to stay at a constant brightness. Flickering means that supply isn't steady.
The interruption can happen in several places: at the globe itself, at the switch, in the wiring feeding the circuit, or occasionally further back at the connection to your home.
Sometimes it's as simple as a loose globe. Other times it's a genuine electrical fault working its way toward something more serious.
Telling the difference is the whole job.
Six Causes, From Common to Rare
Flickering has a wide range of possible causes, roughly in order of how often we actually find them.
- A loose globe or fitting. The simplest cause, and worth ruling out first.
- A worn or failing dimmer switch. Especially common with LED globes that aren't dimmer-compatible.
- A loose connection at the switch or fitting. Vibration and age both loosen a wiring connection over time.
- An overloaded circuit. Heavy appliances starting up can cause a visible dip elsewhere on the same circuit.
- A failing LED driver. The electronics inside an LED fitting can degrade and cause flicker before failing outright.
- A loose main neutral connection. Rare, but it affects multiple circuits at once and needs urgent attention.
Are Flickering Lights Dangerous?
A single flickering fitting with a clear explanation, an ageing globe or a dimmer that was never matched to it, isn't dangerous. Fix it and get on with your evening.
Real concern starts once several lights flicker together, once a switch or fitting feels warm, or once buzzing joins in alongside it.
Those combined signs point toward a loose connection somewhere carrying real current, which is a fire risk if left alone.
Flickering that gets noticeably worse whenever heavy appliances run elsewhere is a pattern we'd rather check than have you live with.
What To Do Before We Arrive
Note the pattern. One light or several. All the time, or only under certain conditions.
Check the obvious first. A loose globe, or a light that's simply reaching the end of its life.
Avoid touching switches or fittings that feel warm. Leave that circuit alone and mention it when you call.
How We Fix the Fault for Good
First we rule out the easy answers: the globe itself, the fitting, and whether the problem sits on one circuit or spreads across several.
Testing at the switch, the fitting and the board itself then narrows things down to the actual failing connection.
Where the flicker touches more than one light, we look at the shared circuit and the wiring feeding it, since a single-fitting fault behaves quite differently to a circuit-wide one.
The scope decided, we walk you through it and set a written price before anything gets touched.
If a repaired fitting starts playing up again and it's on us, our workmanship guarantee has it covered, no charge.
Every repair meets the AS/NZS 3000 wiring rules, with a Certificate of Compliance issued once notifiable work is tested.
A Local Angle on Flickering Lights
A good share of the flickering calls we take around Albion Street and comparable rows of older cottages trace back to original circuits that were never designed to carry today's mix of appliances and lighting.
Add a dimmer switch to a circuit built for a single incandescent globe, decades before dimmable LEDs existed, and the mismatch between old wiring and new fittings shows up as exactly this kind of flicker.
That's a compatibility problem, not a loose-connection one, and we know to check for it the moment a property's wiring history goes back this far.
Swapping the globe rarely fixes it in these cases, since the actual mismatch sits at the switch or further back in the circuit.
It's Often the LED, Not the Wiring
LEDs have made this fault more common, not less, and it's worth knowing why before assuming the worst.
A cheap or mismatched LED globe paired with an older dimmer can flicker for reasons entirely unrelated to the wiring behind your walls.
The dimmer switch and the driver inside the globe need to be genuinely compatible, and a mismatch between the two shows up as exactly the kind of flicker people worry is a wiring fault.
Swapping to a dimmer-compatible globe, or having the dimmer itself matched properly to LED loads, solves a surprising number of these calls before anything else needs looking at.
Prevention Beats Repair
A flickering light rarely announces a serious problem on its own, but a pattern of flickering across the house is worth acting on early.
- Match dimmer switches to the globes actually fitted, not the other way around
- Have loose connections at switches and fittings checked periodically
- Keep lighting and heavy appliances on separate circuits where the board allows it
- Get a professional opinion the moment flickering spreads beyond a single room
- Have the board looked at if flickering turns up alongside anything else unusual
Ongoing lighting faults are covered under light installation, and a wider wiring concern points toward electrical repairs.
Other Faults We Chase Down
A board that keeps tripping can share the same root cause, and a warm power point points toward the fault we've covered on overloaded power points.
We take these calls across Annandale and just as often through Camperdown, Rozelle and Balmain.

Common questions
Your Flickering Lights FAQs
The questions homeowners raise most often about a flickering or dimming light.
Is a flickering light an emergency?
Not usually. A single flickering fitting is worth booking in, and it becomes urgent only if you also notice heat, buzzing or a smell at the switch or fitting.
How much does it cost to fix flickering lights?
It depends on whether the cause is the fitting, the switch or something in the wiring. We diagnose first, then quote in writing before doing anything.
Will the repair come with a certificate?
Any notifiable electrical repair comes with a Certificate of Compliance for Electrical Work once it's tested and finished.
How fast can you get to Annandale?
Often same or next day for a standard booking, faster again if there's any smell or heat alongside the flickering.
Do old fuses make this worse?
They can. An old fuse-style board doesn't always show a voltage dip as clearly, so flickering can be the main clue something's under strain.
How do you find the fault?
We test the circuit, the fitting and the switch in turn, along with the connections at the board, rather than assuming it's the globe.
