Nelson is a suburb in transition — long-held acreages on one side, surveyed lots and new estates arriving on the other, all supplied by the Endeavour Energy network. High Demand Electrical provides accredited ASP Level 2 services across both, with a Certificate of Compliance for every completed job.
Two kinds of Nelson, one accredited team
Half of Nelson still runs on rural-style supply: overhead lines, private poles and long mains runs. The other half is being cut into residential lots with underground servicing. Both worlds involve work on the network side of the meter, which NSW restricts to Level 2 accredited electricians.
High Demand Electrical covers the lot — old infrastructure and new connections alike — throughout Nelson, Box Hill and Annangrove under Endeavour Energy accreditation.


Connecting the next generation of lots
As Nelson's paddocks become streets, each new dwelling needs its connection designed, applied for and constructed. We take that entire process on — application to Endeavour Energy, underground mains from the pillar, meter installation — and deliver energised, compliant supply on the builder's timeline.
Existing rural lines nearing retirement
The overhead runs feeding Nelson's original acreages have carried power for a long time, and age shows in leaning poles and sagging spans. We assess what's still serviceable, replace what isn't and re-string spans to current standards — keeping the older properties as safe as the new ones next door.

Overhead today, underground tomorrow
With new underground-serviced estates rising around them, many Nelson acreage owners are choosing to bury their own supply too. We manage the conversion end to end: trenching the route, installing conduit and cable, and switching over at the network with the shortest outage we can arrange.
When the network flags a problem
Subdivision activity brings inspectors, and inspectors bring defect notices — often for older private assets that were fine until someone looked closely. If your Nelson property receives one, we'll interpret exactly what's required, complete the rectification and close the notice with Endeavour Energy on your behalf.
