A Sydney full house rewire is an AS/NZS 3000:2018 (the Wiring Rules) compliance exercise from switchboard to power point. Licensed electrician is mandatory — unlicensed electrical work is a criminal offence under the Home Building Act 1989. The finished work is documented via a Certificate of Compliance for Electrical Work (CCEW) lodged with NSW Fair Trading and the DNSP.

Switchboard upgrade to a modern consumer-unit-standard enclosure with RCDs (residual-current devices / safety switches) on every circuit is typically bundled. Older VIR (vulcanised india rubber) or TRS (tough rubber sheath) cabling from pre-1970s homes is generally end-of-life and uninsurable.

AskBaily routes your Sydney rewire to a NSW-licensed electrician with documented CCEW history and Ausgrid coordination experience.

What a Sydney rewire involves

Electrician. NSW-licensed. CCEW lodged on completion.
Switchboard. Modern consumer unit with RCD on every circuit. Typical 12-24 poles.
Cabling. TPS (thermoplastic sheath) replacing VIR/TRS. Cat-6 data, HDMI, TV combined.
Safety switches. RCD mandatory on all circuits under AS/NZS 3000:2018.
Ausgrid. Service upgrade where existing capacity insufficient (single to three phase common).
Strata. Owners Corporation consent for apartment riser work.

Frequently asked questions

Do I need to rewire an old Sydney home? If your home still has VIR, TRS, or two-core cabling and older-style fuses (not RCDs), yes. Insurance typically excludes electrical fires on antiquated wiring.

Can I DIY electrical work? No. Unlicensed electrical work is a criminal offence in NSW. Even minor additions require a licensed electrician.

How much does a Sydney rewire cost? A$8,500-A$14,000 for a 2-bedroom apartment rewire. A$18,000-A$24,000 for a 3-4 bedroom house rewire including switchboard upgrade. A$26,000-A$28,000+ for larger homes with complex cabling paths and additional data/AV integration.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.
