Legal Requirements for Plumbers

Most state licensing bodies require plumbers to hold public liability insurance as a condition of their licence. Additionally:

  • Workers compensation is mandatory in all states if you employ anyone
  • VIC: The VBA requires public liability as part of registration
  • QLD: QBCC requires insurance evidence for licence renewal
  • NSW: Fair Trading requires insurance for certain licence classes

Public Liability Insurance

Plumbing work can cause significant property damage — a faulty connection or incorrect installation can flood a property, damage flooring, walls and belongings. Public liability is non-negotiable.

Cover LevelBest ForTypical Annual Cost
$5 millionSolo residential plumber, low-risk work$700 – $1,100/year
$10 millionMost plumbers (recommended)$1,000 – $1,600/year
$20 millionCommercial and industrial plumbing$1,500 – $2,500/year
Tip: Make sure your policy covers hot water system installation and gas work specifically if you do gasfitting. Some public liability policies exclude gas work — always read the PDS.

Tools and Equipment Insurance

A high-pressure water jetter alone can cost $10,000–$40,000. Drain cameras, press tools and specialist equipment add up fast. Tools insurance covers theft, damage and loss.

  • Get a full inventory: List every piece of equipment with purchase value and replacement cost
  • Van overnight cover: Check whether tools left in a locked van overnight are covered — many policies limit or exclude this
  • Excess: $250–$500 per claim is typical
  • Annual cost: Approximately 2–3% of insured value

Income Protection

Plumbing is physical work with real injury risk — backs, knees, shoulders, cuts and burns. If you're off work for 3 months, can you pay your mortgage? Income protection replaces up to 75% of your income while you're unable to work.

  • Waiting period: 30 days is common for plumbers given the risk profile. The 30-day premium vs 60-day premium difference is worth it.
  • Own occupation: Critical — make sure the policy covers inability to do plumbing work, not just "any occupation"
  • Cover amount: Up to 75% of your pre-disability income
  • Tax deductible: Yes, if held outside super
