How to Quote Plumbing Work in Australia

Complete guide for plumbers on how to quote residential plumbing jobs. Covers pricing, material costs, common jobs, and tips for winning more work in Australia.

Plumbing Quote Essentials

Every plumbing quote should include: a description of the work, materials list with quantities and prices, labour (hours or fixed price), call-out fee (if applicable), GST, and compliance certificates. For renovation work, include rough-in and fit-off as separate line items since they happen at different stages of the build.

Pricing Methods for Plumbers

Hourly rate: $90–$140/hour + materials. Fixed price: preferred by customers and wins more jobs. Call-out fee: $80–$150 for the first 30 minutes. For regular maintenance (blocked drains, tap replacements), fixed pricing is standard. For renovation work, quote a fixed price for rough-in and fit-off separately.

Common Plumbing Job Costs in 2026

Blocked drain: $150–$500. Tap replacement: $150–$350. Toilet replacement: $300–$600. Hot water system replacement: $1,500–$3,500. Bathroom rough-in: $2,000–$5,000. Gas fitting (per appliance): $200–$500. These are typical installed prices for the Sydney/Melbourne market — regional areas may vary.

Quoting Renovation Plumbing

Bathroom and kitchen renovation plumbing is typically quoted in two stages: rough-in (moving pipes, installing new waste and water lines before tiling) and fit-off (connecting fixtures after tiling is complete). Always specify what's included in each stage. Plumbing relocations (moving a toilet or shower) add significant cost and should be quoted separately.

Tips for Winning More Plumbing Jobs

1. Respond to quote requests within 24 hours. 2. Provide a detailed, professional PDF quote — not a text message estimate. 3. Include photos of the existing work in your assessment. 4. Offer options (e.g., repair vs replace). 5. Follow up within 48 hours if you haven't heard back. A professional quote makes you look more trustworthy than competitors.
