Heckenberg's streets of 1960s cottages sit at the heart of the old Green Valley estate, where original switchboards and service lines are still common. High Demand Electrical carries Level 2 accreditation on the Endeavour Energy network and handles the suburb's supply repairs, board replacements and storm callouts without needing a second contractor on site.
Heckenberg's ageing infrastructure, handled properly
Your electricity travels from Endeavour Energy's street mains, along a service cable, through a point of attachment and metering, and into your switchboard. Work on any of that requires Level 2 accreditation, which High Demand Electrical holds for the entire Endeavour Energy footprint including Heckenberg.
Most homes here were connected in the same few years of the 1960s, so their infrastructure is ageing in unison. We renew it street by street, certifying each job to AS/NZS 3000 and issuing a Certificate of Compliance Electrical Work on completion.


Boards overdue for their first upgrade
Many Heckenberg switchboards have never been touched since installation, which means fuse wire, no safety switches and panels that predate every modern standard. A new board with full RCD protection is one of the cheapest safety improvements an older home can get, and we complete the changeover including the network disconnection in one visit.
Storm season and falling lines
Mature street trees around Heckenberg and Green Valley give the area its character but punish service cables in high winds. If a line comes down or your point of attachment is torn loose, we respond around the clock, secure the hazard, and restore supply in coordination with Endeavour Energy rather than leaving you in the dark.

New life for old consumer mains
The cable from the pole to your meter is your responsibility, and in Heckenberg it is often the original 1960s run. We replace tired overhead mains, or take the opportunity to move the connection underground for a cleaner frontage, and handle every approval the switch requires.
Thinking about an electric car?
EV ownership is spreading through the south west, but a home charger on Heckenberg's original supply capacity is asking for tripped mains. We assess what your connection can carry, upgrade it where necessary and leave you with a supply that charges the car overnight without dimming the house.
