Typical cost in 2025
Most homeowners pay around $6,000 for a 3-bedroom house, full rewire with new switchboard
What affects the price?
Property size
A 2-bed unit may cost $3,000ā$5,000. A 3-bed house typically runs $5,000ā$8,000. A 4ā5 bed home can reach $10,000ā$12,000+. Each additional circuit adds $500ā$1,000 in labour and materials.
Age of wiring
Homes built before 1985 may have aluminium wiring, which is a fire hazard and requires complete replacement. Cloth-covered wiring from the 1960sā70s is brittle and must be removed carefully, adding labour time.
Switchboard upgrade
Most rewires include replacing the old fuse board with a modern switchboard and safety switches (RCDs). A full switchboard upgrade alone costs $1,200ā$3,000 but is essential for safety and insurance.
Number of circuits and outlets
More power points, lighting circuits, and dedicated circuits (oven, air conditioning, EV charger) mean more materials and time. Modern homes typically need 12ā20 circuits.
Compliance certificate
A licensed electrician must issue a Certificate of Compliance for Electrical Work (CCEW) upon completion. This is required by law and essential for insurance and property sale.
Typical cost breakdown
Estimates are based on Australian average rates in 2025. Prices in Sydney and Melbourne are typically 10ā20% higher than other capital cities.
Frequently asked questions
How do I know if my home needs a rewire?
Warning signs include: aluminium wiring (common in 1970sā80s homes), cloth-insulated cables, a switchboard with ceramic fuses, flickering lights, tripping circuit breakers, or a property that hasn't had electrical work in 25+ years.
Is aluminium wiring dangerous?
Yes ā aluminium wiring expands and contracts more than copper, which loosens connections over time and creates fire risk. All aluminium wiring should be either replaced or have approved connectors fitted at every join by a licensed electrician.
Do I need to move out during a rewire?
It's recommended. Power will be off for large portions of the working day, and electricians need unrestricted access to all rooms. Most rewires take 3ā7 days.
Does a rewire require council approval?
No council approval is required, but the work must be done by a licensed electrician who will self-certify with a CCEW. In some states (e.g. NSW, VIC), the work may also need to be inspected by the local energy distributor for switchboard upgrades.
Will my home insurer cover a rewire?
Standard home insurance does not cover rewiring as it's a maintenance issue, not accidental damage. However, failing to rewire an unsafe electrical system can void your insurance coverage if a fire occurs.
