How Much Does It Cost to Rewire a House in Australia? (Price Guide)

A full house rewire in Australia will cost anywhere from $3,000 to $20,000+. The numbers represent a very broad range, and for good reason. Smaller homes and properties with simple access generally sit near the lower end, while large, older homes with difficult-to-access spaces tend to incur higher rates.

In short, the final price depends on the size of the house, its age, accessibility, the number of power points, and whether the switchboard also needs upgrades. So, treat the figures mentioned in this blog as guidelines, not fixed quotes. They’ll provide a better starting point to compare prices before you make any decision.

If you’re trying to gauge the cost to rewire house wiring, size is the easiest place to start. Bigger homes need more cables, more labour, and usually more outlets. However, floor area isn’t the whole story. A compact brick home with poor roof access can cost more than a bigger weatherboard house with easy access.

Here’s a quick comparison by home size:

For many homes, the realistic starting point to rewire the house may be closer to $3,000, not the lowest number you might spot online. Once you add a second storey, extra bathrooms, a shed, or lots of new outlets, the cost of rewiring jumps quickly. What’s more, the charges for larger family homes can push well beyond $15,000 when the existing layout is messy or quite spread out.

Power points and switches seem cheap on their own, but they add up very quickly before you know it. Each point can add about $65 to $120, depending on the job and accessibility.

This matters because modern homes need far more outlets than older homes were built with. A medium-sized house may need 20 to 50 points once you count power points, light switches, data points, and appliance circuits. Considering these numbers, the sockets alone can add thousands to the bill.

Older homes often have too few outlets for today’s lifestyle choices. If extension cords are everywhere, the rewiring scope usually grows. More rooms mean more appliances, and more wet areas mean more points, and therefore more cost.

Labour usually accounts for the biggest chunk of rewiring costs, often 50 to 70 per cent of the total fees. Electrician rates can range from about $35 to $120 per hour. On average, licensed sparkies charge around $100 to $120 per hour, depending on the job and location. Knowing the pricing range can help you calculate how much electricians charge per hour when comparing different quotes.

Materials also matter. Copper cabling, fittings, clips, safety switches, and protective gear all add to the bill. Additionally, a new switchboard will cost between $700 and $1,000, while related cabling work can add another $2,000 to $3,000. So, if you need switchboard upgrades in Melbourne as well, it can push the total well above the costs of a basic rewire.

Two homes can have the same number of bedrooms and wildly different quotes. That’s because the cost to rewire a house isn’t only about size. You also need to account for how hard it is to complete the job safely, neatly, and to current standards.

A clean, open layout with plenty of space saves time by improving access. In comparison, closed-off walls, tight cavities, and old wiring do the opposite. Simply put, the challenge of rewiring the property matters as much as the house itself.

Older houses often hide nasty surprises in their walls. Outdated wiring, poor earthing, brittle insulation, and switchboards that no longer meet current safety rules can all extend the work scope. Once a sparky opens things up for inspection, the quote may change, depending on the need to cover more than simple wire replacements.

The accessibility level changes everything. Homes with easy roof and underfloor access are cheaper to work on. In contrast, bricked walls, concrete sections, tight roof spaces, high ceilings, and finished interiors mean slower, more careful work. Such constraints can add about 20 to 50 per cent, or several thousand dollars, to the final bill.

Where you live in Australia impacts labour rates. Metro areas usually cost more than regional areas, while some rural jobs may be 20 to 30 per cent lower. On the other hand, very remote locations can push prices back up.

The number of storeys matters as well. Double-storey homes need longer cable runs and more time on ladders or in tight spaces. Similarly, detached garages and sheds add distance, while occupied homes often slow the job because sparkies need to work around furniture, routines, and safety risks. Permits or inspection charges may also apply, adding anywhere between $50 and $500 to the total.

Most people don’t need rewiring quotes every year, so it’s easy to compare the wrong things. The smart move is to look past the numbers and check what’s included. That way, you can tell the difference between a fair quote and one that looks cheap only because half the work is missing.

If you’re asking, “How much does rewiring a house cost?”, there’s no one-size-fits-all answer. Instead, a proper quote can answer this in detail, and should spell out the charges for:

• Labour and materials
• The number of power points, switches, and circuits
• Switchboard work and safety switches
• Testing, compliance, and final checks
• Any wall or ceiling access work
• Exclusions, such as patching, painting, or asbestos issues

It is recommended to get at least three quotes and compare work scope, not only prices. A cheap figure can leave out crucial safety work or compliance items that may appear later as extras. If you’re in Victoria, looking for companies that offer professional house rewiring services can also help you understand what a full scope looks like.

Low quotes aren’t always bargains. Sometimes they only account for the bare minimum. As a result, you’re more likely to pay for “additional charges” that pile up as the work continues.

Watch for vague wording, no mention of testing, no allowance for switchboard upgrades, very low point counts, or unclear clean-up and patching fees. These gaps often turn into extra fees once work starts. So, if the quote feels off, it probably is.

An in-person inspection is still the best way to get a solid figure. Photos help, but they rarely show what sits behind walls or above the ceiling. Being careful about the quote now can help avoid nasty surprises halfway through the job.

The cost of house rewiring in Australia can start at a few thousand dollars for a small home, and go past $20,000 for large or difficult jobs. The biggest price drivers are accessibility, age, outlet count, and switchboard needs. Use these ranges as a guide to budget accordingly. Then, get detailed quotes based on your home’s size, layout, and safety issues.

Rewiring a house is a significant investment, but it’s essential for safety, efficiency, and long-term property value. Costs in Australia can vary depending on the property size, age, and layout complexity. That being said, cutting corners is never worth the risk.
