Winston Hills took shape in the late 1960s and early 1970s, and its generous brick homes are now well into their second half-century on the Endeavour Energy network. High Demand Electrical brings ASP Level 2 accreditation to Winston Hills for the mains renewals, supply upgrades and switchboard modernisations these established properties increasingly need.
Renewing Winston Hills' original infrastructure
The service lines, consumer mains and metering across much of Winston Hills date from when the suburb was first connected — and after fifty-plus years, renewal is due. That work sits on the network side of your property, where only an Accredited Service Provider is authorised to operate.
High Demand Electrical holds Level 2 accreditation with Endeavour Energy and services Winston Hills along with Northmead and Baulkham Hills. Every repair or upgrade is documented with a Certificate of Compliance Electrical Work and completed to AS/NZS 3000 and the NSW Service and Installation Rules.


What half-century-old wiring hides
Original cabling in Winston Hills homes has spent decades baking in roof cavities, and the supply equipment outside has weathered the same years. Recurring fuse failures, warm switch plates or a meter box that smells hot are signs worth investigating promptly. We inspect the network side and give you an honest condition report.
From fuse wire to full protection
Rewirable fuses were still the standard when Winston Hills was built; safety switches were decades away. Upgrading the switchboard brings RCD protection on every circuit plus the capacity that modern living assumes. Because we're Level 2 accredited, the supply disconnection, board replacement and reconnection all happen in one scheduled visit.

Where your service line lands
The point of attachment — where Endeavour Energy's service line meets your home — corrodes and loosens with age, and Winston Hills fascias have held theirs a long time. We repair and relocate attachment points and replace the consumer mains running from them, often while raising clearances to current standards.
Extra capacity for renovations and extensions
Winston Hills renovations tend to be substantial — second storeys, ducted air conditioning, outdoor kitchens. Before the build starts, we arrange temporary disconnection so trades can work safely, then upgrade the supply to three-phase or higher amperage and reconnect it, so the finished home has the capacity its new floor plan expects.

Secure Your Grid Connection
If your Winston Hills home is showing its electrical age, call High Demand Electrical. We'll assess the supply side honestly and quote the fix with no surprises on invoice day.

Don't wait for an outage to force your hand.
