For Level 2 electrical work in Hornsby, Castellano Electrical is your authorised, fully insured local choice — connected, disconnected and certified to Ausgrid's standards. Whether you need a new connection, an urgent after-hours disconnection, underground power or a three-phase upgrade, we handle the work and the Ausgrid paperwork end to end.
Locally, an Upper North-Shore centre with bushland-fringed homes where tree-related overhead damage and underground conversions are common. Near landmarks such as Westfield Hornsby, Hornsby Aquatic Centre and Florence Street Mall, that means a steady mix of new connections, service upgrades and consumer-mains work — all of it network-side jobs that only a Level 2 ASP can legally perform.
Hornsby falls within the Ausgrid distribution area, so any connection, disconnection or service upgrade here must be carried out by a Level 2 ASP authorised for Ausgrid — and we are. Ausgrid operates the electricity network across the Sydney CBD, eastern suburbs, inner west, lower and upper north shore, northern beaches, the Central Coast and the Hunter.
Plenty of Hornsby projects quietly cross into Level 2 territory — buying a home with an ageing overhead service, disconnecting power to start a renovation, or upgrading the supply for a pool or workshop. All of that is network-side work that only a Level 2 ASP authorised for Ausgrid can carry out, and we manage the application and certification from start to finish.
If something goes wrong with the supply in Hornsby — a meter box fire, storm damage to the overhead service, or flooding around the switchboard — it is an emergency that needs isolating at the Ausgrid network immediately. Our 24/7 team responds to Hornsby day or night, makes the site safe, and handles the repair or reconnection.
From our Smithfield base we reach Hornsby in around 40 minutes (about 38km), and we also serve neighbouring Chatswood, Ryde and Baulkham Hills. Our 24/7 emergency team covers Hornsby day and night.
From the first quote to the final Ausgrid sign-off, we keep Hornsby customers informed and the work compliant. Request a free quote for planned work, or call our 24/7 line for anything urgent — and we will confirm your distributor (almost certainly Ausgrid for Hornsby) and scope the job.
