How to Write a Plumbing Quote That Wins Jobs (Template Included)
Why Your Quote Matters More Than Your Price
Most homeowners get 2-3 quotes for plumbing work. They're comparing more than just the bottom line — they're comparing professionalism, clarity, and trust. A handwritten quote on the back of a receipt loses to a professional PDF every time, even if it's $50 cheaper.
What Every Plumbing Quote Must Include
- Your business details: Name, ABN, licence number, phone, email
- Customer details: Name, property address
- Date and quote number: Sequential numbering shows you're organised
- Scope of work: Detailed description of EXACTLY what you'll do
- Materials list: Specific brands/models where possible
- Labour breakdown: Hours estimated and rate
- Total (inc. GST): Clear, no surprises
- Validity period: "This quote is valid for 30 days"
- Exclusions: What's NOT included (e.g., "excludes any hidden damage found during work")
- Payment terms: When and how you expect to be paid
The Scope of Work — Where Most Plumbers Fail
The #1 reason for disputes is vague scope. Compare these:
Bad: "Replace hot water system — $2,800"
Good: "Supply and install Rheem Stellar 330L gas storage hot water system (Model 850330). Includes: disconnect and removal of existing unit, installation of new unit on existing slab, connection to existing gas and water lines, new tempering valve (AS 3500.4 compliant), test and commission. Excludes: any modifications to gas line sizing, electrical work, or council permits if required."
The second quote takes 2 minutes longer to write but eliminates 95% of potential disputes.
Pricing Strategy
Fixed Price vs Hourly Rate
For defined jobs (tap replacement, hot water install, toilet repair), always quote fixed price. Customers hate uncertainty. For investigation work (finding a leak, diagnosing a problem), quote hourly with a cap: "Investigation at $95/hour, capped at 2 hours."
The Three-Option Strategy
For larger jobs, offer three options:
- Basic: Minimum viable fix (cheapest)
- Recommended: Best value solution (middle — most customers choose this)
- Premium: Top-of-the-line option (highest)
This anchors the customer's perception and makes the middle option feel like a smart choice.
