A Sydney kitchen renovation is a licensed-trade sport. Gas appliance installation requires a NSW Fair Trading gas fitter licence and a Certificate of Gas Fitting Compliance lodged on completion. Plumbing requires a licensed plumber and a Certificate of Compliance lodged with Sydney Water for any work on potable, sanitary, or trade-waste services. Electrical requires a licensed electrician and a Certificate of Compliance for Electrical Work (CCEW). Missing any of these certificates is a failure condition at sale-stage conveyancing and, for gas and electrical, a personal-liability issue.

On top of the trade certificates, any kitchen renovation over A$50,000 including scope that is BCA-affecting triggers a BASIX Certificate with energy, water, and thermal-comfort targets. If the kitchen sits in a strata scheme — and 70% of Sydney residential is strata — the Owners Corporation must approve any work affecting common property or the waterproofing and acoustic layer between lots.

AskBaily routes your Sydney kitchen renovation to one NSW-licensed builder who coordinates gas, plumbing, electrical, and strata consent from one contract.

What a Sydney kitchen renovation involves

  • Gas. Licensed gas fitter for cooktop, oven, or instantaneous-water-heater work. Certificate of Gas Fitting Compliance (AS/NZS 5601) filed on completion.
  • Plumbing. Licensed plumber and Sydney Water Certificate of Compliance for any alteration to supply, sanitary, or stormwater. Backflow-prevention device review on commercial-grade kitchens.
  • Electrical. Licensed electrician and CCEW for switchboard, circuit, or safety-switch work. RCD coverage required on all kitchen circuits.
  • BASIX. A BASIX Certificate is required on renovations over A$50,000. Targets affect glazing U-value, ventilation, water fixtures (4-star WELS minimum on taps), and lighting.
  • Strata. Owners Corporation consent for any work affecting common property. Waterproofing on kitchen wet areas sits on the lot/common-property boundary and typically triggers a by-law amendment under SSMA 2015.
  • Asbestos. Pre-1990 kitchens typically contain asbestos in cement sheet splashbacks, vinyl sheet flooring, or insulation boards. A pre-demolition asbestos survey and SafeWork NSW licensed removalist are mandatory over 10 square metres.

Frequently asked questions

Do I need council approval for a Sydney kitchen renovation? Usually no. A like-for-like kitchen refit on an internal footprint is typically exempt development under SEPP (Exempt and Complying Development Codes) 2008 — no DA, no CDC. As soon as you move a gas line, add a new window, alter the external wall, or breach a fire-rated construction, you are into CDC or DA territory. Strata schemes almost always require Owners Corporation consent regardless of council treatment.

What gas and plumbing certificates should I receive on completion? Three documents. A gas fitter's Certificate of Gas Fitting Compliance (pink form). A plumber's Sydney Water Certificate of Compliance. An electrician's Certificate of Compliance for Electrical Work (CCEW). Keep all three with your title documents — buyers' solicitors request them at conveyancing.

How much does a Sydney kitchen renovation cost? A$38,000-A$65,000 for a mid-range flat-pack renovation with quality fixtures. A$70,000-A$95,000 for a mid-spec inner-Sydney full kitchen with stone benchtop, induction cooking, and quality European appliances. A$120,000-A$280,000 for a prime-east or harbour kitchen with bespoke joinery, integrated appliances, and structural wall removal. Budget 8-16 weeks from strip-out to handover, longer if a strata by-law amendment is in play.

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.
