If you own an older home, you may wonder how much to rewire a house. It’s a big question. The answer depends on many things. In Australia, rewiring costs vary a lot. This guide breaks down the numbers. You will learn what affects the price. You will also see how the process works. We aim to give you a clear picture. That way, you can plan your budget. And you can talk to electricians with confidence. Let’s start.
Average Cost to Rewire a House in Australia
Rewiring a house is a major project. The cost can be anywhere from $3,000 to $20,000 or more. That is a wide range. But most homeowners pay between $6,000 and $15,000. The size of your home is the biggest factor. A small unit costs less. A large two‑storey house costs more.
Here is a table with typical costs in Australia. These are based on national averages. Your actual cost will depend on your situation.
These figures include labour and materials. They assume a full rewire. Partial rewiring costs less. But a full rewire is often safer and more efficient. According to online cost guides, rewiring costs for a 3‑bedroom home range from $4,000 to $9,000. Another source, a local electrical company, puts the range at $6,000 to $20,000. The variation shows why you need a detailed quote.
Location matters too. In Brisbane, hourly rates for electricians are around $75 to $110. In Sydney, rates can be $90 to $130. That affects the final bill. For a 3‑bedroom house in Brisbane, you might pay $6,000 to $11,000. In Sydney, it could be $8,000 to $15,000.
Remember, these are estimates. Always get multiple quotes from licensed electricians. Faze Electrical offers transparent pricing. You can see our pricing page for examples of our rates. We provide a fixed‑price quote after inspection. No surprises.
Key Factors That Affect Rewiring Costs
Many factors influence how much you pay. Understanding them helps you budget. It also helps you compare quotes. Here are the main ones.
House Size and Number of Rooms
Larger homes need more wire, more outlets, and more labour. A two‑bedroom unit might cost $3,000 to $8,000. A five‑bedroom home can cost over $20,000. More rooms mean more circuits. Each circuit adds cost.
Age and Condition of Existing Wiring
Older homes often have outdated materials. Vulcanised Indian Rubber (VIR) cables and cotton‑cloth wiring were common before the 1960s. These are now fire hazards. Removing them takes extra time. Also, older homes may need a switchboard upgrade. Adding safety devices like RCDs (residual current devices) adds cost. Compliance with modern standards is critical.
Accessibility
How easy is it to reach the wiring? If the home has a crawl space or unfinished basement, work goes faster. If walls are finished, the electrician must cut openings and later patch them. That adds time and cost. Multi‑storey homes are harder to work on.
Materials Used
Copper wire is standard. It is durable and safe. But copper prices fluctuate. Aluminium wire is cheaper but not always recommended for safety. Fittings like outlets and switches vary in cost. You can choose basic or premium.
Additional Features
Do you want smart home features? Extra data cables for internet? More power points in the kitchen? These increase the price. The Wikipedia article on electrical wiring explains modern requirements. Plan ahead. Adding features later costs more.
Local Labour Rates
Electrician rates differ by city. In Brisbane, the typical hourly rate is $75 to $110. In Melbourne, it is $85 to $150. This affects the total cost.
The Rewiring Process: What to Expect
Full rewiring is a big job. It usually takes several days to two weeks. The process follows a pattern. Knowing it helps you prepare.
First, the electrician inspects your home. They check the current wiring, switchboard, and safety devices. They also note your needs. Where do you want outlets? Any special features? This inspection is free at Faze Electrical.
Next, they give a fixed‑price quote. If you accept, work begins. The electrician turns off power in stages. They may disconnect room by room. This allows you to stay in the home in some cases.
Then the old wiring is removed. The electrician cuts access points in walls and ceilings. They thread new cables through studs and cavities. This is the messy part. Drywall dust is common. They install new outlets, switches, and light fittings.
After wiring, they replace the switchboard if needed. Modern switchboards have RCDs and circuit breakers. These protect you from shocks and fires. One industry blog compares it to an archaeological dig. It is invasive but necessary.
Finally, they patch holes and test everything. A licensed inspector checks the work. You get a compliance certificate. That proves your home meets Australian standards.
To minimise disruption, clear the work areas. Move furniture from walls. Protect valuables with plastic sheeting. Faze Electrical works neatly. We clean up each day. You can expect some noise and dust. But the result is a safe, modern electrical system.
Cost Breakdown: Materials vs Labour
Understanding the split helps you see where your money goes. Labour is the biggest part. It often makes up 60% to 70% of the total. Materials account for the rest.
Labour Costs
Electricians charge by the hour or per project. A full rewire takes a team several days. For a 3‑bedroom home, expect 40 to 80 hours of labour. At $90 per hour, that is $3,600 to $7,200. Licensed electricians cost more than apprentices. But you want a qualified pro. Safety is not the place to save.
Materials Costs
Wire is the main material. A typical home needs about 500 to 1,000 metres of cable. Copper wire costs around $1 to $3 per metre. Other materials include:
- Outlets and switches: $10 to $50 each
- Switchboard and breakers: $800 to $2,500
- Light fittings: $20 to $200 each
- Cable clips, conduit, junction boxes: $100 to $300 total
Upgrades like smart home controls add cost. But they add convenience. Faze Electrical uses quality components. Our pricing page shows examples of typical costs.
To save money, consider a partial rewire. Focus on high‑risk areas like the kitchen and bathroom. But a full rewire is more future‑proof. It adds value to your home and gives peace of mind.
When to Rewire: Signs Your Home Needs It
Not sure if you need a rewire? Look for these warning signs. They indicate outdated or unsafe wiring. If you see any, call a licensed electrician.
Flickering or Dimming Lights
Lights that flicker when you use an appliance are a red flag. It means your circuits are overloaded. This can cause overheating and fires.
Frequent Tripping Breakers
If your circuit breaker trips often, it cannot handle the load. Old wires may be damaged. A rewire fixes this.
Burning Smell or Discoloured Outlets
A burning plastic smell near outlets or switches is serious. It means wires are overheating. Turn off the power and call an electrician immediately.
Two‑Prong Outlets
Homes built before the 1970s often have two‑prong outlets without a ground. Modern appliances need a ground for safety. Rewiring adds grounded outlets.
Old Wiring Materials
Homes from the 1910s to 1960s may have VIR or cotton‑cloth wiring. These are now illegal for new installations. They are fire hazards. Also, knob‑and‑tube wiring is dangerous. Many insurers refuse to cover homes with it.
Aluminium Wiring
Aluminium wire was used in the 1970s. It is not as safe as copper. Connections loosen over time. This can cause sparks and fires. Rewiring with copper is recommended.
No RCD Protection
Modern homes must have RCDs (safety switches) on all circuits. They shut off power if a fault occurs. Without them, you risk electrocution. An upgrade is essential.
According to industry experts, humming noises from ceiling fans can also indicate wiring issues. Get a professional check.
Frequently Asked Questions
How much does it cost to rewire a 3 bedroom house in Australia?
For a typical 3 bedroom home, you can expect to pay between $6,000 and $12,000. This cost includes labour and materials. The final price depends on your location, the accessibility of wiring, and any upgrades you choose. Always get an itemised quote from a licensed electrician.
Can I stay in my house during a rewire?
In most cases, yes. The electrician will disconnect power room by room. You may have to use temporary lighting. Plan for limited power in some areas for a few days. Discuss this with your electrician beforehand to prepare.
How long does a full house rewire take?
A full rewire usually takes between 3 and 10 days. A small two bedroom home might take 3 to 5 days. A larger four bedroom home can take 7 to 14 days. The timeline depends on the home’s size, complexity, and any unexpected issues discovered during the job.
Do I need a permit for rewiring?
Yes. In Australia, electrical work must comply with state regulations. A licensed electrician will obtain the necessary permits and arrange for inspection. This ensures your new wiring meets Australian standards. Never bypass this step.
Will rewiring add value to my home?
Absolutely. A modern electrical system is a strong selling point. Buyers appreciate safety and the ability to run modern appliances. Many sellers recoup a large portion of the cost through increased property value. Plus, you get peace of mind.
What is the difference between partial and full rewiring?
Partial rewiring replaces only certain circuits or rooms. It is cheaper, but may leave some old wiring in place. Full rewiring replaces all wiring from the switchboard to every outlet. It is more expensive but ensures the entire system is safe and meets current standards. For older homes, full rewiring is often recommended.
How often should I rewire my house?
There is no set time, but a good rule is every 20 to 30 years. If your home has older wiring materials or you experience electrical problems, call an electrician sooner. Regular safety inspections every 10 years can catch issues early.
Do electricians offer warranties on rewiring work?
