Electricians in DoncasterProject homes from the orchard years, now ageing.

Doncaster stayed orchard land until the project builders arrived, and most of its houses went up between the 1950s and 1980s. A house that age may still have its original switchboard. The network is ageing too: United Energy says every transformer at its Doncaster zone substation is over 50 years old. We'll match you with a licence-checked electrician who upgrades boards in homes like yours, where we have one.

Doncaster's houses and network

Built by project builders

Doncaster and Templestowe's population tripled between 1950 and 1960, and project builders developed much of Doncaster in the 1960s and 1970s.

Apartments on the hill

27.3% of occupied homes were flats or apartments in 2021, and United Energy expects demand around Doncaster Hill to keep growing.

Underground cables

United Energy says its earliest underground cables in the Doncaster and Templestowe area, up to 37 years old, are failing from water treeing, and most of its cable replacement will happen here.

United Energy supplies Doncaster

Its Doncaster zone substation supplies Doncaster, Doncaster East and Doncaster Hill. Faults go to United Energy on 13 20 99.

Power out? Work out whose problem it is

  1. Look down the street

    If the neighbours are dark too, it's the network. Call United Energy on 13 20 99 or check its outage map. Underground cable faults are theirs to find and fix.

  2. Check your own board

    If it's just you, look for a tripped safety switch and flip it back on once.

  3. Unplug and retry

    If it trips again, unplug everything, reset, then plug things back in one at a time to find the culprit.

  4. Call an electrician

    If it trips with nothing plugged in, leave it off. A burning smell you can't trace is a 000 call.

What a 50-year-old board usually needs

A 1960s or 1970s board may have no safety switches at all, and little spare room for new circuits. Adding a heat pump, an induction cooktop or an EV charger is often the point where it has to change.

Homes built or renovated before 1990 likely contain asbestos somewhere, and WorkSafe Victoria lists switchboard backing boards as a typical spot. A careful electrician checks before drilling.

Where we'd start

In a Doncaster project home, we'd have the switchboard assessed before any renovation or new appliance, and ask for room on the new board for the next ten years of plans. If your street has underground power and outages keep happening, report every one to United Energy so it's on their record.

Questions

Straight answers.

Why does our underground power in Doncaster keep failing?

United Energy says some of its oldest underground cables in Doncaster and Templestowe are failing as water gets into the insulation, and it expects most of its cable replacement to happen here. Those cables belong to the network, so report outages to United Energy rather than an electrician.

Does a 1970s house need hardwired smoke alarms?

By law, homes built before 1 August 1997 only need battery-powered alarms, at least one on each level. If you're replacing the board anyway, ask the electrician about hardwired, interconnected alarms in the same visit.
