Product liability insurance may be relevant if a plumbing business makes, sells or supplies goods, including through a repair or service, but it is not automatically mandatory for every plumber. The business.gov.au guide, Types of business insurance, describes cover for injury, death or property damage to another person or business when caused by the product (figures checked 1 October 2026). The relevant questions are therefore what the business supplies and whether the potential claim involves one of those product-caused outcomes.
Does supplying a product make product liability insurance compulsory?
No—not by itself. Business.gov.au says a business may need insurance because of law or because the people it deals with require it, while other types of insurance are the business’s choice. Legal requirements depend on the type of business and the relevant jurisdiction.
Some states and territories require public liability insurance for certain occupations. That does not mean every plumber must carry product liability insurance, and a public liability requirement should not be treated as proof of a separate product liability requirement.
The supplied-goods wording also does not mean every repair or service is automatically a product. It refers to businesses that make, sell or supply goods, even when the supply takes the form of a repair or service.
| Business activity or issue | What the guidance indicates |
|---|---|
| The business makes, sells or supplies goods | Product liability insurance may be relevant |
| Goods are supplied through a repair or service | The business may still fall within the supplied-goods description |
| A product may cause injury, death or property damage | These are the outcomes described as covered |
| Insurance is required by law or by people the business deals with | The need for cover depends on the applicable requirements |
What does product liability insurance cover?
Business.gov.au identifies the following outcomes where another person or business is affected by the product:
- Injury
- Death
- Property damage
The important trigger is that the product causes the event. Merely selling or supplying goods does not, by itself, establish that a covered event has occurred.
A product-related dispute could involve different issues, including product-caused harm, negligence or the quality of professional services. The correct policy therefore depends on what caused the alleged loss, not just on whether a plumber supplied an item.
Is product liability different from public liability insurance?
Yes. Business.gov.au describes the main trigger differently:
| Insurance type | Trigger described by business.gov.au |
|---|---|
| Product liability | The product causes injury, death or property damage |
| Public liability | Negligence causes death, injury or property damage |
A claim may raise more than one issue, so a plumber should not assume that one policy will respond where another would. The policy’s PDS is the place to check the definitions, insured events, exclusions, conditions and limits.
Professional indemnity insurance is another possible question for a business providing professional advice or services. Business.gov.au says it can help cover legal action costs arising from claims against professional advice or services, as well as certain client losses caused by mistakes, neglect or contract breaches. Its relevance depends on the work being performed and the policy wording.
What should a plumber check before arranging cover?
Start with the business’s actual activities:
- Whether it makes, sells or supplies goods, particularly as part of a repair or service.
- What kind of goods or products it supplies and how they enter the business.
- Whether the likely issue is a product-caused event, negligent conduct, damage to the plumber’s own goods, or a problem with professional services.
- Whether a client, contract or other party requires a particular type of insurance.
- Whether any legal requirement applies to the business, its occupation or its state or territory.
- Whether an existing policy already responds to the relevant risk or whether separate cover is needed.
Business.gov.au advises businesses to seek professional advice about insurance required by law and to discuss policy options with an insurance broker or authorised insurer.
An authorised general insurer can be checked on the Australian Prudential Regulation Authority’s register. An insurance broker’s licence can be checked on the Australian Securities and Investments Commission’s professional register.
What should the PDS confirm?
Before relying on product liability insurance, check the PDS for:
- The definition of a product and the types of goods, products or services included.
- Whether goods supplied during repair or service work fall within the cover.
- The exact insured events and the meaning of product-caused injury, death or property damage.
- Relevant exclusions, conditions, limits and claim requirements.
- Any territorial, contractual or other restrictions that apply to the business.
This is general information, not financial or legal advice. Check the relevant regulator or government page for requirements applying to the business, then check the policy’s PDS for the exact cover.

FAQ
Does every plumber need product liability insurance?
No. It may be relevant when the business makes, sells or supplies goods and a claim involves injury, death or property damage caused by the product. It is not automatically mandatory for every plumber.
Does the rule change if goods are supplied during a repair or service?
Business.gov.au says a business may need product liability insurance if it makes, sells or supplies goods, even where the supply takes the form of a repair or service. The PDS should confirm how the particular policy treats that work.
Does product liability insurance cover any problem with supplied goods?
The guidance focuses on injury, death or property damage caused by the product. Supplying goods alone is not the same as suffering one of those outcomes, and the PDS determines the detailed cover.
Is public liability insurance the same as product liability insurance?
No. Business.gov.au describes product liability around harm caused by the product, while public liability is described around death, injury or property damage caused by negligence. Check both the claim circumstances and the policy wording.
What should a plumbing business check before deciding?
Check the goods supplied, the potential cause of the claim, any legal or client requirement, and the exact PDS. Advice from a broker, authorised insurer or business adviser can help determine which policy needs review.
