House rewiring in Traralgon and the Latrobe Valley

A house rewire replaces the cable that runs from the switchboard to every light, switch and power point, usually along with the outlets and switches themselves. A full rewire of a three bedroom house sits in the Melbourne guide range of $8,400 to $21,000, and a part rewire of the worst circuits or rooms is priced on the circuits involved. Most rewires in the Latrobe Valley start because a check or a renovation found old rubber or cloth insulated cable still in service.

This site does not rewire houses. An independent licensed electrician who gets your enquiry inspects the wiring, prices the scope and carries out the work under their own licence.

How do you know a house needs rewiring?

The age of the cable matters more than the age of the house, since some older homes were rewired decades ago and some newer ones had cheap extensions. Signs that point toward a rewire, each of which is a reason to have the wiring looked at rather than proof on its own:

• Rubber or cloth covered cable visible in the roof space, under the floor or behind a removed switch plate.
• A burning or hot plastic smell near a switch, light or power point.
• Switch plates or outlets that feel warm to the touch.
• Breakers or fuses that trip or blow often, with no single appliance to blame.
• Lights that flicker across several rooms rather than one fitting.
• Two-pin outlets or very few outlets per room.
• Cable joined with tape in the roof, or junction boxes nobody can explain.

If you are not sure what you are looking at, start with an electrical safety check. Energy Safe Victoria advises a wiring check on any house more than 30 years old, and that is the page that covers it.

Why do so many Valley houses reach this point?

Traralgon grew strongly after the Second World War as the power generation industry expanded, much of it through the old State Electricity Commission, and Loy Yang was built through the 1970s and 1980s, according to the Traralgon entry on Wikipedia. Churchill was established from 1965 as a service town for the Hazelwood Power Station, on quarter-acre blocks with most early homes built by the Housing Commission of Victoria (Wikipedia).

That leaves the Valley with streets of houses from the same few decades, many still on parts of their first wiring. If your home in Churchill or nearby has a roof space an electrician can move around in, most new cable can be dropped in from above with little damage to walls.

Full rewire or part rewire?

Option	What is replaced	When it suits	Disruption
Full rewire	All circuits, outlets, switches and usually the switchboard	Old cable throughout, or a major renovation	Highest: power off in stages over several days
Part rewire by circuit	Only the circuits with old or damaged cable	Mixed wiring, with some circuits already updated	Moderate: only affected rooms lose power
Part rewire by room	Cable and outlets in chosen rooms, such as a kitchen	Renovating one area at a time	Low to moderate
Rewire during renovation	New cable run while walls or ceilings are open	Any renovation that strips linings	Lowest added disruption

The Melbourne price guide treats a part rewire of the worst circuits as a reasonable middle option. Once an electrician has tested every circuit, they can tell you which parts can stay and which cannot.

How disruptive is a rewire?

Less than many people expect if the house has roof and underfloor access. In a typical job:

1. The electrician inspects, tests and labels each circuit, and agrees a plan for which rooms are done first.
2. New cable is run through the roof space and subfloor, dropping into wall cavities from above or below.
3. Where a cavity is blocked by noggins or brick, the wall may need chasing, which means cutting a channel, laying the cable and patching.
4. Old outlets and switches are replaced with new ones on the new cable, and the old cable is disconnected and made safe.
5. The switchboard is replaced or updated so the new circuits have circuit breakers and safety switches.
6. Every circuit is tested before it is put back into service, and the certificate is issued.

Families often stay in the house through a rewire, with one or two circuits off at a time. A temporary lead may be run to the fridge. Wall chasing and patching is where most of the extra cost and mess comes from, according to the same Melbourne guide, so homes with good access are cheaper to rewire.

Once you know which rooms worry you most, you can describe the rewiring job and an electrician can say whether a part rewire is worth considering.

How much does rewiring a house cost?

Job	Melbourne guide range
Rewiring a whole three bedroom home	$8,400 to $21,000
Replacing a single phase board during the rewire	$945 to $2,950

These are Melbourne metro figures from an October 2026 electrician price guide, not quotes for Traralgon. Local travel, the type of wall linings and how much chasing is needed all move the final number. Part rewires are quoted on the rooms or circuits involved, so get the electrician to list exactly which circuits are included.

What makes a rewire cost more or less:

• Ceiling height and roof pitch, which decide how easily cable can be run.
• Solid brick internal walls or plaster on lath, which need chasing.
• The number of outlets and lights, since each one is a new fitting.
• Whether the switchboard needs replacing as part of the job.
• Extras such as data cabling or new circuits for appliances added while access is open.

Should the switchboard be done at the same time?

Usually it makes sense. New cable connected to an old fuse board leaves the weakest part of the system in place, and doing both together saves a second round of disconnection and testing. The rewire or switchboard comparison sets out when one job is enough and when you need both, and the switchboard upgrades page covers the board on its own.

What will a careful electrician insist on?

• Testing before quoting, so the scope is based on measurements rather than a glance at the board.
• A written scope listing which circuits, rooms and fittings are included.
• Disconnecting and making safe any old cable left in walls rather than leaving it live.
• Keeping smoke alarms working through the job, or supplying temporary ones.
• Mentioning anything in the roof that needs a specialist before they can work there, such as damaged insulation or suspected asbestos materials, and stopping until it is dealt with.
• Issuing a Certificate of Electrical Safety at the end; if the switchboard or main earth is changed, that part has to be inspected by an independent inspector before it is turned on.

Next step: what to tell an electrician about your rewire

Give the year the house was built and the number of bedrooms and living rooms. Say whether there is a roof space someone can move around in and whether the subfloor can be reached, and describe the wall linings if you know them. Note any rooms that have already been renovated or rewired, and whether you will be living in the house during the work. Send that in a house rewiring enquiry with your suburb, plus a photo of the switchboard with its cover closed if you can take one.
