National average prices. Select a city above for location-specific pricing.
Plumbing costs in Australia depend on the type of job, your location, and whether it's an emergency. A simple tap repair might cost $120–$250, while a full bathroom rough-in can run $3,000–$8,000. Most solar & batterys charge an hourly rate plus a call-out fee, though many offer fixed-price quotes for common jobs like blocked drains or toilet installations.
Hourly rates typically range from $80 to $200 per hour during business hours, with the national average sitting around $120/hr. After-hours and emergency work usually attracts a 50–100% surcharge. Material costs are almost always charged separately.
What Affects Solar & Battery Costs
Job type & complexity
A simple washer replacement takes 15 minutes. Replacing a hot water system or re-plumbing a bathroom takes a full day or more. Complexity is the biggest cost driver.
Time of day
After-hours work (evenings, weekends, public holidays) typically adds 50–100% to the standard hourly rate. Non-urgent jobs should always be booked during business hours.
Materials & parts
Labour is only half the equation. Parts range from a few dollars for a tap washer to $2,000+ for a hot water unit. Always ask if quotes include materials.
Your location
Sydney and Darwin tend to be most expensive, while Adelaide and Hobart are generally more affordable. Inner-city jobs also attract premiums for parking and access.
Emergency vs scheduled
A burst pipe at 2am will cost significantly more than the same repair booked for Tuesday morning. If it can wait, it should.
Licence & experience
Master solar & batterys with decades of experience charge more, but often work faster and diagnose problems more accurately. Both they and newer solar & batterys carry the same licence requirements.
