The North Shore has Sydney's highest concentration of multi-storey architectural homes, frequently with three-phase supply and 30+ circuits per residence. Switchboard complexity, lighting circuit count, and total appliance load all sit at the top end of residential norms.

⚠ 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)

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 North Sydney

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

Electrical work in North Sydney

Possum and rat damage to roof-space cabling is a Sydney-wide issue but is particularly over-represented in tree-heavy North Shore suburbs — Pymble, Killara, Hunters Hill, and Wahroonga see consistent rodent-related circuit damage.

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.
