Pricing Strategy for Plumbers
- Bundle multiple taps: Offer a discount for doing all taps in the house at once — "While I'm here, want me to check the others?"
- Upsell to replacement: If the tap is old and corroded, recommend replacement rather than repair — better margin and the customer gets a warranty
- Carry common parts: Stock standard washers, O-rings, and ceramic discs in your van to avoid return trips
- Minimum charge: Set a minimum job charge of $120–$150 to make small jobs worthwhile
Is It Notifiable Work?
No. Replacing a tap washer or O-ring is like-for-like maintenance and does not require a Form 7 in QLD. However, if you're replacing the entire tap with a different type that requires pipe modification, it becomes notifiable.
