Mount Colah's family homes climb the ridge between Hornsby and the national park, most of them decades old and many ripe for electrical renewal. High Demand Electrical works the Ausgrid network here as an ASP Level 2 electrician — granny flat supplies, switchboard changeovers, EV capacity upgrades and repairs when the weather wins.
Practical upgrades for ridge-top homes
Most electrical trouble in Mount Colah traces back to age: connections, mains and meter boards installed when the suburb filled out have simply reached the end of their design life. Renewing them is network-side work, and Ausgrid rules are clear that only a Level 2 Accredited Service Provider can do it.
High Demand Electrical brings that accreditation to Mount Colah, Asquith and Mount Kuring-Gai every week. Our work meets AS/NZS 3000 and the NSW Service and Installation Rules, and each job closes with a Certificate of Compliance Electrical Work.


Room for a flat out the back
Mount Colah's block sizes leave real space for secondary dwellings, and plenty of owners are building them. The catch is supply: a granny flat added to an original 1960s connection can overload it. We upgrade the incoming service, run compliant sub-mains and set up the metering so both homes have the power they need.
Overhead lines versus the weather
Ridge-top exposure and heavy tree cover mean Mount Colah's overhead services get tested every storm season. We repair storm-damaged spans and attachment points around the clock, and for properties that keep copping it, we can convert the service underground — one trench, and the problem never comes back.

Getting the driveway EV-ready
With the M1 close by, Mount Colah commuters are switching to electric cars in growing numbers. A home fast charger draws heavily for hours at a stretch, which older supplies were never sized for. We verify your capacity and, where needed, upgrade the connection or move you to three-phase before the charger goes on the wall.
Old fuse boards on borrowed time
If your Mount Colah switchboard still uses plug-in ceramic fuses, it predates safety switches entirely — and it will not cope gracefully with modern loads. A full switchboard replacement, with the supply isolation arranged through Ausgrid as part of our Level 2 service, brings the whole installation up to today's standard in a single day.
