For Level 2 electrical work in Wollongong, Castellano Electrical is your authorised, fully insured local choice — connected, disconnected and certified to Endeavour Energy'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 Endeavour Energy paperwork end to end.
Locally, an Illawarra regional city with a mix of coastal homes and CBD redevelopment driving connection and metering upgrade work. Near landmarks such as Wollongong Harbour, WIN Stadium and University of Wollongong, 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.
Wollongong 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.
Whether you are renovating an older Wollongong home, building new, adding solar or upgrading for ducted air conditioning or an EV charger, the moment the job touches the supply between the Endeavour Energy network and your meter it becomes Level 2 ASP work. A standard electrician cannot legally connect, disconnect or alter that supply, and Endeavour Energy will not energise work done by a non-ASP.
If something goes wrong with the supply in Wollongong — 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 Wollongong day or night, makes the site safe, and handles the repair or reconnection.
From our Smithfield base we reach Wollongong in around 60 minutes (about 75km), and we also serve neighbouring Campbelltown, Liverpool and Sutherland. Our 24/7 emergency team covers Wollongong day and night.
From the first quote to the final Endeavour Energy sign-off, we keep Wollongong 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 Endeavour Energy for Wollongong) and scope the job.
