Three phase power upgrades across Sydney, handled by one crew.

It depends on four things: overhead or underground, the distance from your meter position to the street pole or kerbside pillar, the size of the new switchboard, and whether the existing backing panel is asbestos. Send us a photo of the meter panel and the front of the closed switchboard with the address and we'll come back with a firm number. No surprises on the day.

We lodge the network application the day we quote. Once Ausgrid or Endeavour confirms the connection, we book the connection date and the crew. The on-site changeover itself is one working day. Thorntek owns the timeline from lodgement through to the meter swap, so you're not chasing the network or the retailer at any point.

Yes for the working day of the changeover. We isolate the supply first thing, pull the old consumer mains, build the new switchboard, fit the new three phase mains, and test every connection and circuit. Power is back on by knock-off. Plan ahead for the fridge, the home office and anyone working from home.

Almost always yes. A single phase board isn't built or wired to take a three phase supply. The new board comes with a main switch sized for the new service, a safety switch on every circuit, surge protection built in, and a dedicated three phase circuit pre-run for the EV charger or ducted aircon. If the existing backing panel is asbestos, a licensed removalist handles the removal before the new board goes up.

Your retailer stays the same unless you choose to switch. The plan itself may need re-quoting because three phase tariffs and controlled-load arrangements can differ from a single phase account. The smart meter swap is handled by the network as part of the changeover, not by the retailer. We give you the meter details and changeover date so the retailer can update your account cleanly.

On some older Inner West side streets, parts of the Eastern Suburbs heritage pockets and pockets of the Blue Mountains, the low voltage mains in the street only carry single phase. Before any property upgrade can proceed, the network has to bring three phase down the street. We check the street mains at the application stage, raise it with Ausgrid or Endeavour, and tell you straight whether your upgrade can go ahead or the street needs upgrading first.

Yes. The single phase meter comes out and a three phase smart meter goes in as part of the changeover. The network attends the meter swap the same day we finish, so the new service goes live and the new meter is reading from the moment power comes back on.

Yes. On a weatherboard the existing attachment bracket usually needs replacing on the fascia, bolted back to solid timber so the heavier new service cable hangs safely. On terraces we run the new aerial mains in cleanly and keep the streetscape tidy. The new switchboard goes in the same position the old one occupied wherever possible. The new switchboard goes in the same position the old one occupied wherever possible.

Usually no. An 11 kW or 22 kW charger needs a three phase supply at the property, so if the house is single phase, the supply has to be upgraded first. The upside: once the upgrade is in, the same job adds headroom for the next aircon, the pool heat pump and the granny flat. We design the new switchboard with a dedicated three phase EV circuit so the charger install down the track is a straight bolt-on.
