- Check whether three-phase is already available at your street, if not, the network upgrade is the big cost.

What a three phase power costs in Canberra
Upgrading to three-phase power in Canberra is priced first on whether three-phase already runs in the street, since if the network's three-phase mains pass the home the work is a service upgrade from the street to a new switchboard, while if only single-phase reaches the street the distributor must extend three-phase, a far larger job. The switchboard upgrade, metering change and service run then make up the rest of the figure. The high local labour base lifts the install above the bigger cities.
Three-phase is often wanted in Canberra to run heavy electric heating and ducted systems hard through the cold, frosty winters, as an all-electric home's winter demand can exceed what single-phase comfortably carries, along with workshops, EV fast-charging and large homes. Many established and ex-government suburbs were wired single-phase, while newer estates are commonly three-phase, so availability must be checked with the distributor. The big temperature range and cold snaps drive the heating load that motivates the upgrade. The high local labour base, from a smaller market with less competition, lifts the cost, so booking the work ahead helps, and an old switchboard is often replaced at the same time.
A three-phase upgrade is licensed electrical work that must be done by a licensed electrician in the ACT under Access Canberra, and the connection to the network is coordinated with the distributor, who must supply or confirm the three-phase service. For a Canberra home, the clearest way to price a three-phase upgrade is by whether the street already has three-phase, then the switchboard, metering and service run, with the winter heating load the common driver.
