Ausgrid vs Endeavour Energy: How to Tell Which Network Your Sydney Property Is On

If you've ever rung your electrician about a power issue and the first thing they've asked is “are you Ausgrid or Endeavour?”, you're not alone. Most Sydney homeowners have no idea which network their property sits on, and honestly, there's no reason you would — until you need a new connection, a switchboard upgrade, a solar system, or you're clearing a defect notice. That's when it suddenly matters a lot.

Why there are two (well, three) networks in NSW

Electricity distribution in New South Wales is split between a handful of companies who each own and maintain the poles, wires and substations in their patch. In the Sydney basin, that's mainly Ausgrid and Endeavour Energy, with Essential Energy covering regional and outer areas. These aren't retailers — they don't send you a power bill — they're the businesses responsible for the physical network your home connects to. The Service and Installation Rules of New South Wales (SIRNSW) sets out the shared minimum standards all three follow, but each distributor also runs its own Electrical Safety Rules and its own approval processes on top of that shared baseline.

Roughly speaking, who covers what

Ausgrid covers the Sydney CBD, the Eastern Suburbs, the Inner West, the Northern Beaches, North Shore, and out through Newcastle and the Central Coast. Endeavour Energy covers Greater Western Sydney — think Parramatta, Penrith, Liverpool, Campbelltown, the Blue Mountains and down towards the Illawarra fringe. The boundary between the two isn't always intuitive; it follows old network infrastructure history rather than council lines, so two streets that feel like the same suburb can occasionally sit on different networks.

How to actually check

The most reliable way is to look at a recent electricity bill — your retailer (AGL, Origin, Energy Australia, whoever) will list your distributor, usually in the fine print near your NMI (National Metering Identifier) number. Both Ausgrid and Endeavour also publish network area look-up tools on their websites where you can punch in an address. If you're mid-renovation and waiting on paperwork, your Level 2 electrician or ASP (Accredited Service Provider) will confirm this in about ten seconds because it's the very first thing they check before lodging any connection or alteration request.

Why it actually matters

Once you know your distributor, a few things follow. Each network has its own turnaround times for new connections and meter work, its own solar export limits and approval paperwork, its own defect notice process if an inspector flags an issue with your service line, and its own vegetation clearance expectations if you've got trees near overhead wires. An ASP who works across both networks (and there aren't many who genuinely do both well) needs separate authorisations and needs to lodge separate types of requests depending on which network you're on — it's not a one-size-fits-all form.

The takeaway

It's a five-minute check that saves a lot of confusion later. If you're planning any electrical work that touches your connection to the grid — a switchboard upgrade, solar, a new granny flat supply, clearing a defect notice — find out which network you're on first, and make sure whoever you're calling is actually accredited to work on that network.
