A plumbing business owner in Australia typically nets $95,000 to $130,000 per year after expenses. Employee plumbers earn $85,000 to $105,000 per year (SEEK, May 2026). The owner premium is real, but it comes with overhead and compliance obligations.

This page covers employee vs owner earnings, what plumbing businesses charge by service type, and what affects how much you take home.

Based on SEEK (May 2026), Indeed (March 2026), and IBISWorld (2025) data. Actual earnings vary by location, service mix, and expenses. Consult a registered accountant for projections specific to your situation.

What Do Employed Plumbers Earn in Australia?

The employee baseline matters. If business ownership does not pay meaningfully more than employment after all costs, the added complexity is hard to justify.

Employed plumbers in Australia earn $85,000 to $105,000 per year on average, according to SEEK (May 2026). Indeed (March 2026, 804 salaries reported) shows an average of $47.19 per hour nationally. Experience and specialisation both push earnings higher:

• Apprentice (year 1 to 2): $22,000 to $35,000 per year.
• Qualified plumber (under 3 years): $70,000 to $85,000 per year.
• Experienced plumber (3 to 7 years): $85,000 to $105,000 per year.
• Specialist (gas fitting, commercial, drainage): $100,000 to $130,000+ per year.

A plumbing business owner who manages their business well and builds a solid client base should consistently earn above the employed rate.

What Do Plumbing Businesses Charge?

Rates charged to clients in Australia in 2026:

• Residential repair and maintenance: $70 to $100 per hour. General repairs, leaks, fixtures, blocked drains. Consistent, repeat work but competitive pricing.
• Emergency callouts: $150 to $300+ call-out fee, plus hourly rate. After-hours and emergency work commands a significant premium. This is where strong margins sit for responsive operators.
• Gas fitting: $80 to $150 per hour. Specialist licence required. Lower competition, stronger margin than general residential work.
• Commercial plumbing: Contract-based, often negotiated per project. Reliable pipeline of work for operators with commercial relationships. Larger jobs, steadier income.
• Hot water system installation: Products plus labour, typically $1,500 to $4,000+ per job depending on system type. Strong margin because the parts markup and labour combine.
• Drainage and excavation: Project-based, equipment-intensive. Higher job values but equipment hire or ownership adds to costs. Effective for operators with the right gear.

Plumbing businesses that mix emergency callout work with regular maintenance clients and some commercial contracts consistently achieve the strongest net earnings. Relying solely on residential repair work at standard rates is the lowest-margin approach.

What Affects Plumbing Business Earnings?

• Emergency work ratio. Emergency callouts are where the hourly rate is highest. Operators who are available after hours and on weekends earn significantly more per hour than those who work standard hours only.
• Location. Rates in Sydney and Melbourne are higher than regional areas. The IBISWorld 2025 data shows 28,615 plumbing businesses nationally across a $22.2 billion market. Dense urban markets have more competition but support premium pricing.
• Licensing scope. A plumber with gas fitting and backflow prevention endorsements can take on more types of jobs and charge more for them. Broadening your licence scope is one of the clearest ways to increase earnings.
• Overhead management. Vehicle costs, tool maintenance, licensing renewals, insurance, and marketing are the main fixed costs. Solo operators who keep these lean and efficient consistently take home more.
• Call-back rate. Repeat clients and referrals are the highest-margin work because there is no acquisition cost. Operators who do the job right first time and follow up generate the most efficient revenue.

Is It Worth Starting a Plumbing Business in Australia?

For licensed plumbers ready to manage the business side, yes. Here is the honest picture:

‍

• Strong and ongoing demand. Australia's plumbing services industry is worth $22.2 billion across 28,615 businesses (IBISWorld, 2025). The industry is forecast to grow at 2.0% annually through 2028-29, driven by housing construction, renovations, infrastructure spending, and major projects including the 2032 Brisbane Olympics pipeline.
• Earnings above employment. A well-run solo business nets $95,000 to $130,000 per year, consistently above the employed rate of $85,000 to $105,000. The gap grows further as the business scales.
• After-hours availability creates a real premium. Plumbing has genuine emergency demand at any hour. Owners who structure their business to handle callouts after hours and on weekends access the highest per-hour rates in the industry.
• Year-round work. Plumbing does not have the seasonal quiet periods of landscaping or exterior trades. Maintenance, repairs, and emergencies run all year.
• Licensing and compliance. A Plumbing Contractor Licence is required to operate a plumbing business. Requirements vary by state. Insurance is mandatory in most states as a condition of licensing. These barriers limit competition.
