Why does flicker get worse when the AC starts?

Air conditioners draw a large inrush current on start-up. If there's a loose connection upstream, the voltage drop across that connection is briefly significant, dimming the rest of the house. The flicker is the upstream connection complaining about the load.

Should I be concerned if my Sydney home is more than 30 years old?

Yes. Aged installations frequently develop loose terminations, oxide build-up at aluminium joints, and tired main switches. We recommend a switchboard inspection as part of any post-purchase or pre-sale electrical check.

Could solar PV cause flickering?

Yes — particularly older inverters cycling between export and import modes, or a damaged DC isolator after a storm. Modern inverters with grid-following control should not flicker the household supply, but legacy or undersized installations can.

How quickly can you respond?

We dispatch 24/7 across all Sydney suburbs. Whole-house flicker is priority emergency dispatch (30–90 minutes). Localised flicker is usually attended within 4–24 hours. Call 0433 462 902.

Is it safe to leave flickering lights on while I sleep or go to work?

A single lamp near end-of-life is low risk, but whole-house or intermittent flicker can mean a loose connection that arcs and generates heat inside your walls overnight. Until the cause is confirmed, switch off non-essential circuits at the switchboard and book a diagnostic as soon as possible.

Will my house catch fire if the flickering comes and goes and seems to fix itself?

Intermittent flicker that appears to self-correct is one of the more dangerous patterns — a deteriorating or loose connection often stabilises briefly as load conditions change, but arcing continues inside the cable or fitting between those calm periods. Treat self-correcting flicker as an active warning sign, not a resolved one, and have it inspected promptly.

How much does it cost to diagnose and fix flickering lights in Sydney?

Cost varies depending on the cause — swapping a mismatched dimmer is far less involved than replacing a consumer mains or main switch. We provide a fixed-price quote after the initial diagnostic so there are no surprises; call 0433 462 902 or book online to arrange a time.

What's the difference between one light flickering and lights flickering all over the house?

A single flickering light typically points to a failing lamp, a loose connection in that one circuit, or a fitting issue — contained and lower urgency. Whole-house flickering almost always indicates a fault at the main switch, incoming neutral, or consumer mains, which carries a higher risk of outage or fire and warrants same-day attention.

Who should I call — Ausgrid or an electrician — if my neighbours seem to have the same flickering?

If neighbours confirm identical flickering at the same time, the fault is likely on Ausgrid's network and you should report it directly to Ausgrid (13 13 88) — that's their responsibility at no cost to you. If your home flickers while neighbouring properties are unaffected, the fault is on your side of the meter and you need a licensed electrician.

Western Sydney homes — post-war brick veneers across Bankstown and Liverpool, Federation cottages through Parramatta and Auburn, modern estate builds from Penrith to Pennant Hills — span a 70-year vintage range with switchboard ages and conditions to match.

In Western Sydney, post-war fibro and brick-veneer homes flicker from aged wiring and overloaded boards, while big modern builds and master-planned estates can flicker when single appliances pull hard on one phase of an unbalanced three-phase supply.

⚠ Stop — Call Immediately if You Notice Any of These:

Flickering that intensifies when high-draw appliances (oven, kettle, AC) cycle on
Whole-house flicker affecting every circuit
Flickering accompanied by burning smell
Flickering accompanied by a buzzing or humming switchboard
Lights that brighten as well as dim (a strong signal of a broken main neutral)
Tingles from any tap, sink, or appliance during the flicker
Flickering that began after recent storm damage
Flickering with simultaneous failure of electronics (modems rebooting, TVs flickering)

Full guide: Why Are My Lights Flickering? — causes, FAQs & expert advice

About Why Are My Lights Flickering?

Flickering lights stem from a loose neutral, a failing main switch, or a degrading consumer mains — or something minor like an end-of-life LED or a dimmer mismatch. Whole-house flicker, flicker that intensifies under load, or any burning smell signals imminent fire or outage risk — call 0433 462 902, or book a daytime diagnostic. In our experience attending Sydney homes, the cause differs sharply by era: deteriorating consumer mains are common in Federation cottages in Glebe and Annandale, main-switch failures appear in 1990s strata across Pyrmont and Mascot, and dimmer incompatibilities show up in newer North Shore builds in Killara and Lindfield. Sydney Electrical Service is dispatched 24/7 across every metropolitan suburb.

What to Do Right Now in Meadowbank

Identify the scope. Is the flicker in one bulb, one room, one circuit, or the whole house?
Note when it occurs. Is it constant, intermittent, or correlated with appliance use?
Try a different bulb in the affected fitting. If the new bulb behaves the same, the fault is upstream.
Test in isolation. Turn off the dimmer for that circuit and use the bulb at full brightness.
Listen. Buzzing or humming from the switchboard during flicker is a strong upstream-fault signal.
Smell-check the switchboard for any burning odour.
For whole-house flicker intensifying under load, isolate the main switch and call us immediately.
For single-bulb flicker, call us during business hours for a non-urgent diagnostic.
Photograph any switchboard discolouration or damage for our dispatch.

Electrical work in Meadowbank

Meadowbank has changed faster than almost anywhere in the Ryde area. Along the river and around the station you've got a dense cluster of newer high-rise strata towers, while the streets climbing back from the water still hold their original interwar and post-war brick homes and a scattering of older walk-up flats. That split drives two very different kinds of work. The established houses often run ageing two-wire wiring and small boards with no safety switches, where a board upgrade and RCD protection is overdue, while the apartment stock brings common-property switchboards, sub-metering and rising-main questions tied to EV charging in shared car parks.

Sitting close to the Parramatta River, riverside properties also cop more moisture and corrosion on external fittings and meter enclosures than homes further inland. Ausgrid is the distributor across Meadowbank, so new connections, consumer-mains upgrades and metering or point-of-attachment work are Level 2, which we're accredited to handle alongside the switchboard work.

Common Questions

Is flickering always a serious problem?

No. A single end-of-life LED bulb flickering in one fitting is a $5 fix. A whole-house flicker that intensifies when the kettle boils is a serious fault. The difference is scope and correlation.

What's a "broken main neutral" and why does it cause flicker?

The neutral is the return path for current. When it breaks, voltage relative to earth becomes unstable — appliances may receive variable voltage between 0 V and 415 V. Lights flicker, electronics fail, and metalwork can become live. It is one of the most dangerous faults we attend.

Why do my LED bulbs flicker on the dimmer?

Most legacy dimmers are "phase-cut" devices designed for incandescent and halogen bulbs. LEDs require dimmers specifically rated for them — usually labelled "trailing edge" or "LED-compatible." Mismatch causes flicker, buzzing, and reduced bulb life.

Will replacing all my bulbs fix it?

Sometimes — but not when the cause is upstream. If the flicker continues after fresh bulbs of the right type, the cause is in the circuit, the dimmer, or further back at the switchboard.
