Quick answer
Plumbers and gasfitters borrow for vans, jetters and drain cameras, materials for new-home rough-ins, hiring and training apprentices and covering builder payment terms. Lenders separate fast-paying maintenance work from slower builder work, and look at debtors, licences and existing equipment finance. Unsecured options suit most needs; property security helps with larger builder-contract swings.
Key points
- Maintenance work is fast cash; builder work is bigger but slower.
- The mix of the two shapes how much working capital you need.
- Stacked equipment finance can quietly squeeze cash flow.
- Licences for plumbing and gasfitting must be current.
- Common uses
- Vans, jetters, materials, apprentices
- Lenders focus on
- Work mix, debtors, licences
- Unsecured options
- Typically $5k – $500k
- Property-secured
- $20k – $5m
Plumbing is a trade with two very different income streams. Maintenance, emergency and service work is quick, frequent and usually paid on the day. Builder work — rough-ins and fit-offs on new homes and renovations — brings larger invoices but longer waits. Most plumbing businesses do both, and the balance between them decides how much cash the business needs to run. That’s what lenders look at first.
What do plumbers usually borrow for?
- Vans. A fitted-out van for each plumber, stocked with fittings and tools.
- Specialist equipment. Hydro-jetters, drain cameras, pipe relining gear, locators.
- Materials for builder work. Rough-in materials bought ahead of stage payments.
- Apprentices. Wages and training for new apprentices.
- Emergency capacity. Staff and vehicles to offer after-hours service.
- Gas and hot water stock. Units and fittings for installations.
How do lenders look at a plumbing business?
The work mix. How much comes from maintenance and service versus builder and commercial work? A business weighted towards maintenance turns cash quickly; one weighted towards builder work needs a buffer for payment terms.
Debtors. An aged debtors list shows how long builders and commercial clients take to pay.
Licences and financial requirements. Plumbing and gasfitting licences are essential. In Queensland, plumbing is regulated by the QBCC, which sets financial reporting obligations for contractor licensees. Lenders expect licences to be current.
Benchmarks. The ATO’s small business benchmarks for plumbing services give typical cost ratios for comparison.
Existing finance. Many plumbing businesses have several vehicle and equipment loans. Lenders add them all up.
If your vans are full and your diary is too, check your options — no credit check to enquire.
A closer look: service work versus builder work
Imagine two plumbing businesses with the same annual turnover. The first earns most of it from service calls — blocked drains, hot water replacements, leaking taps — paid by card on completion. The second earns most of it from builder rough-ins and fit-offs, invoiced at stages and paid on 45-day terms. The first has cash in the bank most days. The second may be owed a month or more of revenue at any time.
Neither is better; they’re just different. But a lender will size and structure finance differently for each. The service-heavy plumber may need a simple equipment loan. The builder-heavy plumber may need a working-capital line to cover the gap between buying materials and being paid.
Knowing your mix — and showing it clearly — helps a lender match you with the right facility. It also helps you decide whether to rebalance towards service work, which many plumbers find smooths their cash flow considerably.

Questions a lender will ask
- What share of your work is service versus builder?
- Which builders do you work for, and how quickly do they pay?
- How many plumbers and apprentices do you employ?
- What finance do you already have on vans and equipment?
- What will the new equipment earn?
How to strengthen a plumbing application
Split your revenue by work type for the past year. Show your aged debtors. List existing finance with monthly repayments. For equipment, estimate the new work it will bring — relining jobs per month, drain inspections, after-hours calls. These numbers make a lender’s decision easy.
When should a plumber apply?
Before a big builder contract starts, or before winter when hot water and blocked drain calls typically rise. Arranging finance early means you can say yes to work without scrambling.
Common misconceptions about plumbing finance
“More builder work means more profit.” It can, but it also means longer payment terms and more cash tied up. Lenders look at the mix.
“Equipment finance doesn’t count as debt.” It does. Lenders add up every vehicle and equipment repayment.
“Emergency work is too unpredictable to count.” It’s frequent and paid quickly. Lenders value it.
Plumbers who show their work mix, debtors and existing finance usually find lenders ready to help.
Illustrative scenarios
Illustrative: jetter and camera. A three-van plumbing company wants $40k for a hydro-jetter and drain camera to take on more blocked-drain work. Consistent banked income from maintenance jobs supports an unsecured loan sized on turnover.
Illustrative: a new-estate contract. A plumbing contractor signs on for rough-ins across a new estate, paid on 45-day terms, and needs $110k for materials and extra staff. A property-secured facility covers the gap until payments flow.
Secured or unsecured for a plumber?
Unsecured lending of $5k to $500k suits most tools, vans and payroll gaps. Property-secured loans from $20k to $5m help for larger builder-contract swings. Air conditioning installers should see the HVAC guide, and those working closely with builders the builder guide.
Could your plumbing business qualify?
A 60-second enquiry starts things off. There’s no credit check when you first enquire, no string of lenders ringing you under a house, and a real person who understands service and builder work. Please fill it in accurately so we can match you properly first time.
Frequently asked questions
Can a plumber get a business loan without property?
Usually, yes. Plumbing businesses with steady banked income can look at unsecured options sized on turnover and bank statements.
How do lenders view builder work?
As valuable but slower to pay. Builder clients often pay on terms, so the more builder work you do, the more working capital you need.
Can I finance a jetter or drain camera?
Yes. Equipment that opens new work — blocked drains, relining, inspections — is easy to justify. Lenders look at the expected revenue from it.
Does ATO debt stop a plumber getting finance?
Not automatically. ATO debt is considered case by case, particularly with a payment plan in place.
