Castellano Electrical provides licensed Level 2 ASP electrical services across Narellan (2567) and the surrounding Endeavour Energy network area. Whether you need a new connection, an urgent after-hours disconnection, underground power or a three-phase upgrade, we handle the work and the Endeavour Energy paperwork end to end.
Around Narellan — near Narellan Town Centre, Camden Valley Way and Mount Annan Botanic Garden (nearby) — a rapidly expanding South-West suburb dominated by new subdivisions delivered with underground reticulation from day one. Near landmarks such as Narellan Town Centre, Camden Valley Way and Mount Annan Botanic Garden (nearby), 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.
Narellan falls within the Endeavour Energy distribution area, so any connection, disconnection or service upgrade here must be carried out by a Level 2 ASP authorised for Endeavour Energy — and we are. Endeavour Energy operates the network across Greater Western Sydney, the South West, the Blue Mountains, the Southern Highlands and the Illawarra.
Plenty of Narellan 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 Endeavour Energy can carry out, and we manage the application and certification from start to finish.
If something goes wrong with the supply in Narellan — a meter box fire, storm damage to the overhead service, or flooding around the switchboard — it is an emergency that needs isolating at the Endeavour Energy network immediately. Our 24/7 team responds to Narellan day or night, makes the site safe, and handles the repair or reconnection.
From our Smithfield base we reach Narellan in around 33 minutes (about 35km), and we also serve neighbouring Camden, Campbelltown and Liverpool. Our 24/7 emergency team covers Narellan day and night.
From the first quote to the final Endeavour Energy sign-off, we keep Narellan customers informed and the work compliant.
