How Much Does House Rewiring Cost in Australia in 2026?
House rewiring cost in Australia runs $8,000–$15,000 for a typical three-bedroom home in 2026, including a standard switchboard upgrade. A small two-bedroom unit might come in at $5,000–$10,000, while a large double-storey or double-brick home can push past $20,000. Priced another way, electricians quote rewiring work at roughly $120–$250 per point — every power point, light fitting and switch counts as one.
If you've just bought a weatherboard cottage in Brisbane with ceramic fuses, or your Melbourne Californian bungalow still has cloth-covered cabling in the roof, this guide is for you. Rewiring is one of the least visible renovations you can pay for — and one of the most important, because old wiring is a genuine fire and shock risk, not just a compliance headache.
Below we break down the full house rewire price by home size, explain how the per-point pricing model works, and show which levers actually move your quote. The component rates come from the default rate card in Leadkit's electrical calculators — the quoting tools real Australian electricians embed on their own websites.

Key takeaways
- Rewiring a typical 3-bedroom Australian house costs $8,000–$15,000 in 2026, including a standard switchboard upgrade; large or double-storey homes run $12,000–$20,000+.
- Electrical rewiring cost per point sits around $120–$250 — a 3-bed home has roughly 40–60 points, which is why whole-house jobs land in five figures.
- The switchboard is the line item most people forget: a standard upgrade defaults to $1,800 ex. GST on Leadkit's electrical calculator, and $3,500 ex. GST for a large or capacity upgrade.
- The biggest cost drivers are access and construction type — easy roof and underfloor cavities keep labour down; double brick and concrete slabs push it up.
- Homes wired before the 1970s often have VIR (rubber-insulated) or cloth-covered cabling and no safety switches — the classic triggers for old wiring replacement.
- Rewiring is licensed electrical work in every state — DIY rewiring is illegal in Australia, full stop.

How much does house rewiring cost in Australia? {#how-much}
Rewiring a house in Australia costs between $5,000 and $30,000+ in 2026, with most standard three-bedroom homes landing in the $8,000–$15,000 band including a switchboard upgrade. The spread is wide because "a rewire" ranges from re-running cable through an accessible timber-framed home to gutting the electrics of a two-storey double-brick terrace.
| Home type | Typical full house rewire price (2026) |
|---|---|
| 1–2 bed unit or small cottage | $5,000 – $10,000 |
| 3-bed single-storey house | $8,000 – $15,000 |
| 4-bed or double-storey house | $12,000 – $20,000 |
| Large, heritage or double-brick home | $18,000 – $30,000+ |
| Partial rewire (per room or circuit) | $1,000 – $3,000 |
A note on where these numbers come from: the whole-house bands above are a market guide drawn from published Australian electrician cost guides, because full rewires are always quoted after an on-site inspection — no honest sparkie prices one sight-unseen. The component rates later in this post (power points, downlights, safety switches, switchboards) are the default rates in Leadkit's own electrical quote calculator, verified against our production data in November 2026. Leadkit builds those calculators, so that part is our data, disclosed as such — and electricians who embed the calculator set their own rates on top.

Electrical rewiring cost per point — how sparkies price it {#per-point}
Most Australian electricians estimate rewiring at $120–$250 per point, where a "point" is any single termination — a power point, light fitting, switch or hardwired appliance connection. Count your points and you can sanity-check any quote: a three-bedroom home typically has 40–60 points, which at $150–$250 each puts the wiring portion at $6,000–$15,000 before the switchboard.
The per-point model works because the cable run, not the fitting, is where the labour lives. Pulling new thermoplastic-sheathed (TPS) cable through a roof cavity to one point takes similar effort whether it ends in a power point or a pendant light.
Here's how the component pricing looks on Leadkit's electrical quote calculator — these are the national default rates (ex. GST) as of November 2026:
| Item | Default rate (ex. GST) |
|---|---|
| Callout fee | $90 |
| Power point (GPO) install | $180 |
| Downlight install (each) | $110 |
| Pendant light install (each) | $220 |
| Ceiling fan supply and install | $320 |
| Safety switch (RCD) install | $280 |
| Oven hardwire / connect | $180 |
| Switchboard upgrade — standard (typical 3-bed home) | $1,800 |
| Switchboard upgrade — large / capacity | $3,500 |
| Minimum job fee | $120 |
Add 10% GST on top, and the calculator applies a location multiplier — Sydney work runs about 15% above the national baseline, while Adelaide and regional areas come in under it.

It's built for itemised work like adding points and switchboard upgrades rather than whole-house rewires, but it's the fastest way to see how the components of a rewire add up. Results are an indication only — your electrician confirms the final price on inspection.
What's included in a full house rewire price? {#whats-included}
A full house rewire price covers four things: stripping or abandoning the old cable, running new circuits to every point, a new switchboard with modern circuit protection, and the testing and certification that makes it all legal. If a quote looks suspiciously cheap, one of those four is usually missing.
A proper rewire typically includes:
- New cabling throughout — modern TPS cable replacing the old runs to every power and lighting point.
- A new switchboard — ceramic fuses out, circuit breakers and safety switches (RCDs) in. RCDs cut power in milliseconds when current leaks to earth, and they're now required on circuits in every state.
- Consumer mains check — the cable from the street connection point to your switchboard. If the consumer mains are undersized or degraded, upgrading them is usually a separate line, and Leadkit's calculator deliberately doesn't carry a default rate for it because it varies too much by site.
- Earthing and bonding brought up to the current wiring rules (AS/NZS 3000, the standard every sparkie works to).
- A Certificate of Compliance for Electrical Work — your proof the work was done by a licensed electrician and tested. Keep it; you'll want it at sale time.
What's usually not included: patching and painting the wall chases, new light fittings beyond basic hardware, and data or TV cabling. Ask for these as separate lines so quotes compare like-for-like.
Across the electrical quotes generated through Leadkit calculators, the switchboard upgrade is the item homeowners most consistently leave out of their mental budget — it's a four-figure job on its own before a metre of new cable goes in. The callout structure matters too; we've broken down what electricians charge for callouts in Sydney if you want to see how that first hour is priced.
How do you know your old wiring needs replacing? {#old-wiring}
If your home was wired before about 1970 and has never been rewired, assume the old wiring replacement question is "when", not "if". Cabling doesn't last forever — insulation dries out, crumbles and exposes live conductors, usually out of sight in the roof space.
The classic red flags:
- VIR cabling — vulcanised india rubber insulation, standard before the 1960s. The rubber perishes and flakes off, leaving bare copper in your ceiling. Energy regulators treat it as a fire risk, and Energy Safe Victoria has long warned homeowners about degraded old wiring of exactly this type.
- Cloth-covered or lead-sheathed cable — same era, same problem.
- Ceramic fuses in the switchboard — if you're replacing fuse wire by hand, your board predates safety switches by decades.
- Two-wire circuits with no earth — common in very old lighting circuits; nothing protects you from a fault.
- Infinity-brand cable — the opposite problem: modern cable sold between 2010 and 2013 that was recalled nationally because its insulation degrades prematurely. If your home was wired or extended in that window, check the ACCC's Product Safety recall information and ask an electrician to inspect.
Day-to-day symptoms worth acting on: breakers or fuses that trip repeatedly, flickering lights, warm or discoloured power points, a buzzing switchboard, or that faint fish-like smell of overheating insulation.
A licensed electrician can run an inspection — typically a few hundred dollars — and tell you whether you need a full rewire or staged work. In NSW, you can verify any electrician's licence for free through NSW Fair Trading; every other state has an equivalent register.
What makes rewire house cost higher or lower? {#cost-drivers}
Access is the single biggest variable in rewire house cost — the price gap between an easy home and a hard one is mostly labour hours, not materials. Copper cable costs what it costs; crawling through a 40cm roof void over three days is what you're really paying for.
The levers that move your quote:
- Construction type. Timber-framed and brick-veneer homes with good roof and underfloor access are the cheap end. Double-brick walls and concrete slabs mean chasing walls or running surface conduit — slower, messier, dearer.
- Storeys. Two-storey homes lose the easy ceiling access for the ground floor. Expect the upper band of the price table.
- Point count and additions. Rewiring is the cheapest moment you'll ever have to add points. Extra GPOs at $180 ex. GST each cost far less mid-rewire than as separate visits later — and many owners add EV-ready circuits while the walls are open. We've covered EV charger installation costs in Australia separately if that's on your list.
- Asbestos. Homes built before 1990 may have asbestos sheeting around switchboards or in wall cavities. Licensed removal is a separate trade and a separate bill — Safe Work Australia sets the framework, and your electrician can't legally just drill through it.
- Living in the house during works. An occupied home means staged circuits, nightly make-safes and more labour than an empty one. A vacant house between settlement and move-in is the perfect rewiring window.
- Switchboard and mains condition. If the consumer mains need upgrading or the metering gear is obsolete, add to the budget.
This is a price indication only. Your tradie will confirm the final price after assessing the job.
How does house rewiring cost vary by city? {#by-city}
Sydney is the most expensive city to rewire a house in, typically pricing 10–20% above the national average, while Adelaide and regional areas generally come in under it. Melbourne and Perth sit a touch above baseline, with Brisbane close to the national average.
That pattern isn't a guess — it mirrors the location multipliers built into Leadkit's electrical calculator defaults: Sydney ×1.15, Melbourne and Perth ×1.05, Brisbane ×1.00, Adelaide ×0.92, and regional areas ×0.90 on the work (the callout fee stays flat). Applied to the national 3-bed band, that puts a Sydney rewire at roughly $9,000–$17,000 and an Adelaide one at $7,500–$14,000.
Two caveats worth knowing:
- Older housing stock concentrates in inner suburbs. An inner-west Sydney terrace or inner-Melbourne bungalow is more likely to be double-brick with degraded VIR cabling — so the harder jobs cluster exactly where rates are highest.
- After-hours work multiplies labour. Leadkit's calculator defaults apply a 1.5× labour loading after hours. For a planned rewire, there's rarely a reason to pay it — book standard hours.
Wherever you are, get two or three itemised quotes from licensed locals. Industry bodies like Master Electricians Australia maintain member directories if you're starting from scratch.
How to keep your rewiring cost down {#save-money}
The cheapest rewire is the one that's planned once, done once, while the house is empty. You can't legally do any of the wiring yourself, but you control the conditions that set the labour hours.
Practical ways to trim the bill:
- Time it with other works. Rewiring during a renovation — while plaster is already off — avoids paying twice for wall chasing and patching.
- Empty the roof space and clear access before the crew arrives. Hours saved are dollars saved.
- Decide your point layout up front. Changes mid-job cost more than extra points quoted from day one.
- Bundle the switchboard, safety switches and smoke alarm circuits into one job rather than drip-feeding visits — the callout and setup get paid once.
- Get itemised quotes, not lump sums. Per-point and per-item lines let you compare three quotes properly and drop the padding.
- Don't chase the cheapest number. A rewire is a 40-plus-year asset. Verify the licence, ask for the Certificate of Compliance in writing, and check the quote includes testing.
One thing not to economise on: a partial rewire that leaves known VIR or recalled cable live in the walls. Insurers ask questions about known defects, and a half-done job can cost more to finish later than it saved up front.
Frequently asked questions {#faqs}
Q: How long does it take to rewire a house?
A: A typical three-bedroom, single-storey Australian home takes about 3–7 working days to rewire; double-storey or double-brick homes can run 7–10 days. A partial rewire of a single room or circuit is usually a half-day to a day. The timeline stretches when access is tight, asbestos is found, or the home is occupied and circuits have to be staged so you keep power each night. Your electrician should give you a day estimate alongside the price — treat a firm schedule as part of the quote.
Q: Can you live in the house while it's being rewired?
A: Yes, in most cases — electricians stage the work circuit by circuit and make everything safe each evening, but expect periods without power, ceiling access panels open, and furniture shuffled. It also adds cost, because staged work is slower than an empty-house run. If you can rewire between settlement and moving in, or during a holiday, you'll usually get a better price and a faster job.
Q: How much does it cost to rewire a 2-bedroom unit?
A: Rewiring a two-bedroom unit typically costs $5,000–$10,000 in 2026. Units have fewer points than houses, but strata approvals, shared riser access and concrete construction can offset the smaller size. In a strata building you'll need body-corporate sign-off before work touching common property, so build a few weeks of lead time into the plan. This is a price indication only. Your tradie will confirm the final price after assessing the job.
Q: Is it illegal to rewire your own house in Australia?
A: Yes — all fixed wiring work in Australia must be done by a licensed electrician, in every state and territory. That includes replacing a power point, not just whole-house rewiring. DIY electrical work voids insurance, attracts serious fines and is genuinely dangerous. The flip side: licensed work comes with a Certificate of Compliance, which is your legal proof the installation was tested and meets AS/NZS 3000.
Q: Does old wiring affect home insurance?
A: It can. Insurers may ask about the age and condition of wiring, and a known, undisclosed defect — like perished VIR cabling flagged in a building report — can complicate a claim after an electrical fire. A documented rewire with a compliance certificate removes the question entirely, and some owners find it helps at renewal time. If a pre-purchase inspection flags old wiring, cost the rewire into your offer rather than hoping it holds.
Q: Do electricians charge a callout fee for rewiring quotes?
A: Many electricians quote larger jobs like rewires free of charge, but inspections of old wiring often carry a callout or inspection fee — commonly $90–$150 — because assessing a roof full of old cable is real work. Callout structures vary a lot by city; we've broken down electrician callout costs in Melbourne as an example of how that first-visit pricing works.
Q: Is a partial rewire worth it, or should I do the whole house?
A: A partial rewire makes sense when the old cable is confined — say, one extension wired in the 1990s is fine but the original 1950s circuits aren't. At $1,000–$3,000 per room it spreads cost, and a good electrician will stage it so each stage stands alone safely. But if degraded cable runs through the whole roof, partial work just defers the bill while the risk stays live. Get the inspection first, then decide on evidence, not hope.
Final tips and next steps {#final-tips}
House rewiring cost in Australia comes down to three numbers: your point count, your switchboard, and your access. Count the points, budget $8,000–$15,000 for a standard three-bed home in 2026, add the four-figure switchboard line most people forget, and get two or three itemised quotes from licensed electricians before committing. This is a price indication only. Your tradie will confirm the final price after assessing the job.
An unsafe ceiling full of crumbling rubber insulation won't announce itself — if your home is 50+ years old and has never been rewired, book the inspection this month, not "someday".
