Depending on business size, you could be looking at anywhere from £114,000 ($217,455 AUD) to £1,987,000 ($3,789,805 AUD). This is the first thing most aspiring plumbing business owners want to know. But it's not the full picture. Revenue is one thing, profit is another.

1. How much does a plumbing business owner make?

A plumbing business owner’s pay is what’s left after the business covers its costs and tax, so revenue alone doesn’t tell you much. Wages, the ute, materials, insurance and tools all come out before you get paid.

Before we talk about what a plumbing business owner takes home, it helps to know what the business brings in. Here’s what plumbing and gas businesses typically invoice in a year, from solo operators through to big crews.

Keep in mind that’s not your pay. Materials, wages, van running costs and other overheads all come out first. Think of these as a guide to the kind of turnover businesses your size are doing before those costs hit.

These are average yearly invoiced revenue figures for Plumbing & Gas businesses using Tradify, rounded to the nearest thousand and shown in local currency. A handful of high-volume businesses lift the averages, so plenty of plumbers will invoice less than what’s shown.

In Australia and the UK, the bigger the team, the more revenue comes in. New Zealand breaks that pattern, with solo plumbers (NZ$563,000) out-invoicing small teams (NZ$472,000). The NZ numbers come from a small sample of 34 sole traders, 23 small teams and 13 medium teams, so don’t read too much into that gap yet.

3. Why revenue is not take-home pay

Revenue is what a business invoices, not what the owner keeps. Before a cent reaches your pocket, a few things get paid first:

• Materials
• Wages and other labour costs
• Running costs like vans, insurance and software
• Tax

Tradify’s reports show revenue only, with none of these costs taken off. That’s why two plumbing businesses can invoice the same amount and still pay their owners very different wages. One might be burning through materials and paying a big crew, while the other runs lean.

4. How to set a healthy profit margin

Work your prices out from what the job costs you, not from what it feels like it should earn. Before you lock in a rate, tally up:

• Labour
• Materials
• The van
• Insurance
• Tools
• Software

Then factor in the time you can’t bill. Quoting, driving between jobs, paperwork, time off and the quiet patches between jobs all go unpaid, so a full diary doesn’t mean a full week of billable hours.

Your own wage is a cost of the business too, so put it in once with everything else. Once every cost is covered, whatever’s left over is the profit the business makes from the work.

5. Where the figures come from

• Australia: Australia's Top-Earning Trades Report, Plumbing & Gas row. The report uses anonymised Tradify customer data and describes its figures as invoiced revenue, not profit. It doesn't state exact dates.
• United Kingdom: The UK's Top-Earning Trades Report, Plumbing & Gas row. It covers 3,000+ UK trade businesses using Tradify, from June 2024 to May 2026.
• New Zealand: Tradify trade performance data for the 12 months to 31 August 2026, based on approved invoices. The Australian and UK reports don't cover New Zealand, so these figures come from Tradify's trade performance dataset. Sample sizes are 34 sole traders, 23 small teams and 13 medium teams.

Each source uses its own period and method, so the three rows aren't a like-for-like snapshot.
