Signs your old Melbourne home needs a rewire

Melbourne has a rich stock of Federation, Edwardian, and mid-century homes. These are beautiful buildings — but their original electrical wiring was never designed for modern loads, and it has now had many decades to degrade. Rewiring an old home is a significant job, but it is often the right call for safety and peace of mind.

How old is "old enough to worry about"?

Wiring installed before the 1980s is worth having inspected. Wiring from the 1950s and earlier may use rubber insulation that has become brittle and cracked with age. This type of wiring — sometimes called "rubber and cloth" wiring — is not inherently illegal to have in your home, but it presents a real fire and shock risk as it ages. Some insurers are also reluctant to cover homes with known old wiring.

Warning signs inside the home

• Flickering or dimming lights that are not caused by a faulty globe, particularly if they flicker when you use another appliance on the same circuit.
• Warm or discoloured power points and switches. Outlets should never feel warm to the touch. Yellowing or scorch marks around a power point indicate heat from a loose connection or degraded wiring.
• Frequently tripping breakers or blown fuses on circuits that are not obviously overloaded.
• A burning or hot smell that you cannot trace to an appliance.
• Power points with only two slots (no earth pin). These are a strong sign of very old wiring and, in many cases, indicate the absence of earthing on that circuit.
• Round-pin power points. Australia phased these out decades ago. If your home still has them, the wiring dates from at least the 1960s or earlier.

What an electrician looks for

A licensed electrician can open power points and light fittings to inspect insulation condition, check earthing continuity, and test the circuit with proper equipment. Some faults are only visible once the walls are opened — which is why a professional inspection matters more than a visual check from the outside.

Partial vs full rewire

Not every old home needs every circuit replaced at once. In some cases, an electrician can prioritise the circuits that are in worst condition or carry the heaviest loads — the kitchen and laundry circuits especially — and return to the rest later. A full rewire is usually most economical when renovation work is already exposing walls and ceilings.

If you are buying or selling a period home, or if you have had any of the warning signs above, it is worth getting a proper electrical inspection. An independent assessment gives you an honest picture of what you are dealing with before problems escalate.
