From established brick homes on quarter-acre blocks to the new apartments rising around the metro station, Castle Hill runs on the Endeavour Energy network — and High Demand Electrical is accredited to work on it. We carry out Level 2 connections, upgrades and defect rectification, with a CCEW certifying every job.
Why Castle Hill calls a Level 2 ASP
Castle Hill has changed faster than almost any suburb in the Hills. Older homes near Baulkham Hills and Glenhaven are being renovated, knocked down or converted, and each of those projects eventually needs someone authorised to touch the network side of the supply.
That's the role of an Accredited Service Provider. High Demand Electrical holds Level 2 accreditation with Endeavour Energy, meaning we can disconnect, reconnect, upgrade and meter your supply directly — no waiting on a third party to finish your project.


More power for growing households
A lot of Castle Hill houses still run on single-phase supply installed decades ago. Add a pool, ducted air conditioning and a workshop, and the original capacity starts tripping under load. We upgrade homes from single to three-phase and from 100 to 200 amps, replacing the service line and metering in the same visit.
Received a defect notice from Endeavour Energy?
A defect notice means the network distributor has spotted a problem with your private electrical assets — often the point of attachment, consumer mains or an ageing service line. There's a deadline attached, and ignoring it risks disconnection. We rectify defects across Castle Hill, lodge the paperwork with Endeavour Energy and close the notice out for you.

Disconnect and reconnect for renovations
Knock-down rebuilds and major extensions are everywhere in Castle Hill. Before demolition starts, the supply has to be safely disconnected at the network; once the build is done, it needs reconnecting and often upsizing. We coordinate both ends so your builder is never standing around waiting for power.
Supply for shops and commercial premises
Castle Hill's commercial strips and business precincts depend on reliable supply, and fit-outs frequently uncover capacity problems the lease never mentioned. We handle commercial supply upgrades, new connections for shopfronts and metering changes, working with Endeavour Energy so your trading hours take the smallest possible hit.
