Set on the ridges above the Georges River between Como and Jannali, Oyster Bay is an established suburb where mid-century homes sit among tall gums — a combination that keeps supply lines and mains on our radar. High Demand Electrical provides ASP Level 2 services throughout Oyster Bay on the Ausgrid network.
Supply-side care for an established suburb
The equipment feeding power into an Oyster Bay home — the overhead service line, the point of attachment on the roof, the consumer mains running down to the meter — can only be repaired or replaced by an Accredited Service Provider. Much of it here dates from the 1950s and 60s, and age shows up as brittle insulation, corroded fittings and capacity that falls short of modern demand.
We renew this infrastructure to AS/NZS 3000 and the NSW Service and Installation Rules, finishing every job with a CCEW for your records.


What sixty-year-old wiring risks look like
Flickering lights, warm switch plates and fuses that blow under ordinary loads are classic signs the supply into an older Oyster Bay home is struggling. The riskiest faults hide in the mains themselves, where insulation breaks down out of sight. An inspection settles the question before a fault forces the issue.
Replacing mains before they fail
Consumer mains renewal is straightforward when it's planned: we isolate the supply, run new correctly rated cable from the connection point to your switchboard, and restore power the same day. Left until failure, the identical job becomes an emergency with your house dark in the meantime.

Trees, storms and the line to your roof
Oyster Bay's canopy is part of its charm and most of its electrical risk. Branches contacting a service line wear through insulation long before they bring it down. We fit tiger tails as temporary protection, re-tension or re-route vulnerable spans, and respond around the clock when weather does its worst.
Second dwellings on generous blocks
Adding a granny flat or studio down the slope? The extra demand usually calls for upgraded mains, and possibly a capacity increase from Ausgrid. We handle the load assessment, the physical upgrade and the metering arrangement, so the new dwelling is properly supplied from day one.
