Tips for Your Electrical Rewiring in New South Wales

A full rewire is recommended for any home with original wiring over 30 years old — old rubber or cloth-sheathed wiring is a fire hazard.

Always ensure your electrician provides a Certificate of Compliance (or equivalent) on completion — this is a legal requirement in all states.

Combine a rewire with a switchboard upgrade to bring your home up to current RCD (safety switch) requirements.

Homes with plaster walls cost less to rewire than brick veneer, as running new cables through brick is more labour-intensive.

Consider adding extra circuits and power points during a rewire — the marginal cost is minimal while walls are already open.

Frequently Asked Questions

How much does it cost to rewire a house in Sydney in 2026?

Rewiring a standard 3-bedroom home in Sydney typically costs between $8k and $20,000. The mid-range average is around $12k including a switchboard upgrade with modern safety switches.

What electrical licence is required in New South Wales?

In New South Wales, all electrical work must be performed by a licensed electrician registered with NSW Fair Trading. It is illegal for unlicensed persons to perform any electrical work in Australia. Your electrician must provide a Certificate of Compliance (or equivalent) upon completion.

How do I know if my Sydney home needs rewiring?

Warning signs include frequently tripping circuit breakers, flickering lights, burning smells from outlets, discoloured power points, and aluminium or cloth-sheathed wiring visible in the roof space. Any home over 30 years old with original wiring should be inspected by a licensed electrician.

Is a switchboard upgrade included in a rewire in New South Wales?

Most New South Wales electricians include a switchboard upgrade as part of a full rewire, as the old board is rarely compatible with modern RCD (safety switch) requirements. A standalone switchboard upgrade costs $1,500–$3,500 but is typically discounted when bundled with a rewire.

How long does a full house rewire take in Sydney?

A full rewire of a standard 3-bedroom Sydney home takes 3–5 days for a home with accessible ceiling and wall cavities. Brick veneer homes take longer (5–7 days) due to more difficult cable access. Power is typically maintained to essential circuits during the process.
