Plumbers insurance is a general term for insurance products that may be relevant to licensed plumbers, plumbing contractors, gas fitters, drainers and plumbing businesses working on residential, commercial and industrial properties.
Plumbing work can involve installing and repairing water supply systems, working with drainage and sewerage, handling pipes and fittings, using specialised equipment and working inside a client’s property. Depending on the cover arranged, insurance may assist with risks such as:
The cover available will depend on the policies selected, the plumbing work performed, business structure, insurer acceptance, policy limits, conditions and exclusions. Particular activities, such as gas fitting, high-pressure drain cleaning, excavation or industrial plumbing, may require specific disclosure or insurer approval.
Plumbers can face risks involving third-party injuries, accidental water damage, tools and equipment, business property, workplace injuries and periods where an injury or illness prevents the business owner from working. The insurance products that may be relevant will depend on your plumbing activities, licence requirements, project types, employees, subcontractors, business assets and contractual obligations.
A Business Insurance Package can combine several selected cover options into one customisable policy. Depending on the insurer, your business activities and the policy selected, available cover sections may include:
Not all sections are automatically included. Some sections may require another cover section to be selected or may need to be arranged separately. Available cover options, combinations and limits vary between insurers and policies. Cover is subject to policy terms, conditions, limits, excesses, exclusions and insurer acceptance.
The cost of plumbers insurance varies depending on the plumbing work you perform, annual turnover, project types, employees and subcontractors, claims history, tools and equipment and the cover options selected. There is no single price that applies to every plumber. Insurers assess the activities and risks of each business before calculating a premium.
Several factors can influence the cost of plumbers insurance. These may include the type of plumbing work undertaken, the size and value of projects, where the work is performed, the number of employees or subcontractors, the value of tools and equipment and the limits and cover types selected.
Plumbers often compare different policy types and cover limits depending on their plumbing activities, project sizes, licensing requirements, client conditions, head contractor requirements, business structure and the value of their tools and equipment.
Premiums are subject to individual underwriting, insurer acceptance and policy terms, conditions, limits and exclusions.
Provide your business details, compare available insurance options and receive your documents once cover has been arranged.

Cover is subject to insurer acceptance and the relevant policy terms, conditions, limits and exclusions.
Insurance and licensing requirements for plumbers in Australia vary according to the state or territory, the type of plumbing work performed and the nature of the project. General plumbing, gas fitting, drainage, roof plumbing and specialist plumbing services can be subject to different licensing and insurance requirements.
There is no single Public Liability Insurance requirement that applies to every plumber throughout Australia. However, some jurisdictions impose specific insurance conditions on licensed plumbers, while other requirements may arise through trade licences, building contracts, head contractors, tenders, construction sites or other commercial arrangements.
Plumbing businesses employing eligible workers should also check the Workers Compensation requirements that apply in the relevant state or territory.
Last reviewed: October 2026.
Note: Requirements vary depending on the type of plumbing work, licence held, contract value, project type, business structure and whether employees or subcontractors are engaged. Plumbing, gas fitting, drainage and broader building work should not be assumed to have the same licensing or insurance requirements. This information is general only and should not be relied on as legal, licensing or compliance advice. Confirm current requirements with the relevant state or territory plumbing, building and Workers Compensation regulator before commencing work.
Plumbing, drainage and gas fitting are regulated construction occupations in the Australian Capital Territory. Contractors must hold the appropriate licence for the work they undertake, with licensing requirements varying according to the plumbing activities performed.
ACT requirements also include obligations for plumbers, drainers and gas fitters to provide evidence of their insurance to clients before supplying services, including advising clients if they do not hold insurance.
Separate professional insurance requirements can apply to particular specialist roles, such as plumbing plan certification or works assessment. Residential building insurance or an approved fidelity fund certificate may also be required for certain eligible building projects, depending on the work and contractual arrangements.
Plumbing contractors should check their licence conditions, insurance obligations and any additional requirements imposed by clients, principal contractors or construction sites.
Plumbing, drainage and gas fitting are regulated trades in New South Wales. A licence or certificate is required to perform plumbing, draining or gasfitting work regardless of the value of the work or whether it is residential, commercial or industrial.
The appropriate licensing category depends on the type of work undertaken. Plumbing businesses should also check whether their activities require additional licensing or supervision arrangements.
Home Building Compensation Insurance is required for eligible residential building work valued above $20,000, including GST. Whether a particular plumbing project falls within the scheme depends on the scope of work and applicable eligibility rules.
Plumbers should also confirm any Public Liability requirements imposed by clients, head contractors, tenders or construction sites. Public Liability and Home Building Compensation Insurance provide different forms of protection and are not interchangeable.
Plumbing and drainage work in the Northern Territory is regulated by the Plumbers and Drainers Licensing Board. The licensing system distinguishes between registered journeymen and advanced tradesmen.
An advanced tradesman licence is required to contract directly for plumbing or drainage work within the regulated licensing arrangements. Additional registration through the Building Practitioners Board is required for certifying plumbing and drainage work.
Gas fitting is regulated separately, and plumbing businesses carrying out gas-related work should check the applicable licensing and safety requirements.
Public Liability Insurance may be required through building contracts, principal contractors, tenders or commercial arrangements. Employers must also consider Workers Compensation obligations for workers covered by the Northern Territory scheme.
Plumbing and drainage work in Queensland is regulated by the Queensland Building and Construction Commission (QBCC). Contractors undertaking plumbing or drainage work generally require the appropriate QBCC contractor licence, regardless of the contract value. An occupational plumbing or drainage licence may also be required to personally perform the work.
The Queensland Home Warranty Scheme applies to eligible residential construction work valued above $3,300, including labour, materials and GST.
Some plumbing activities, such as eligible sanitary drainage work, bathroom fixture replacements, certain water supply installations and work requiring plumbing approval, can fall within the scheme. Other plumbing activities may be excluded, so contractors should confirm whether the particular project is insurable.
Public Liability requirements may also arise through project contracts, tenders, site access conditions or other arrangements.
Plumbing businesses in South Australia must hold the appropriate plumbing, gas fitting or electrical contractor’s licence where they carry out or organise regulated work. Individuals performing the physical trade work must also hold the relevant worker registration.
Plumbing contractors must comply with applicable technical and safety requirements, including issuing electronic Certificates of Compliance for prescribed plumbing work.
Public Liability Insurance may be required through commercial contracts, head contractor requirements, tenders or site-access conditions. Plumbing businesses should confirm whether their licence conditions or particular services impose additional insurance obligations.
Where a contractor also performs eligible domestic building work under a separate building contract, additional building insurance or statutory obligations may apply depending on the project.
Plumbing work in Tasmania is regulated through the state’s occupational licensing system. Plumbers require an appropriate practitioner licence to perform regulated plumbing work, while businesses contracting directly with customers require the relevant plumbing contractor licence.
Tasmanian plumbing contractors must hold Public & Products Liability Insurance in the trading name of the business. The insurance must provide at least $5 million for any one occurrence for Public Liability and at least $5 million in the annual aggregate for Products Liability.
Different licensing classes can apply to water supply, sanitary plumbing, drainage, roof plumbing and specialist activities.
Plumbing contractors must provide a Certificate of Currency as evidence of the required insurance when applying for or renewing their contractor licence. Employed plumbing practitioners working under a licensed contractor are not automatically required to hold a separate contractor insurance policy. Different requirements may apply when undertaking work independently or without payment.
Plumbing contractors should confirm that their insurance meets the relevant licensing conditions and correctly identifies the insured business and activities. Employers must also comply with applicable Workers Compensation requirements.
Plumbing work in Victoria is regulated by the Building and Plumbing Commission. Plumbers must hold the appropriate registration or licence for the work they undertake, with separate classes covering activities such as water supply, sanitary plumbing, drainage, roofing and gas fitting.
Licensed plumbers are required to maintain insurance that complies with the applicable Ministerial Orders. The minimum Public Liability Insurance requirement is $5 million, and the insurance must meet additional prescribed requirements, including provisions relating to completed work liability.
The required insurance includes prescribed cover beyond ordinary Public Liability, including certain liabilities for defective or incomplete plumbing work and consequential financial loss. These requirements depend on the applicable Ministerial Order and work performed. A standard Public Liability policy should not be assumed to satisfy Victorian plumbing licensing requirements.
A Certificate of Currency must identify the licensed plumber and contain the required insurance details and Ministerial Order compliance wording. A standard Public Liability policy may not satisfy these requirements unless it complies with the relevant order.
Plumbing contractors should confirm that their insurance meets the specific Victorian licensing conditions before undertaking regulated work.
Water supply, sanitary and drainage plumbing work in Western Australia is regulated by the Plumbers Licensing Board. Contractors taking responsibility for regulated plumbing work must hold the appropriate plumbing contractor’s licence, while tradespeople and other workers must hold the required licence or permit.
Licensing conditions and authorisations depend on the type of plumbing work performed. Gas fitting is regulated separately, and additional licensing conditions can apply where plumbing businesses provide gas installation or maintenance services.
Public Liability Insurance is commonly requested by builders, commercial clients, principal contractors and construction sites, although there is no single Public Liability requirement applying to all plumbing work across Western Australia.
Home Indemnity Insurance may apply where a contractor is responsible for eligible residential building work under the relevant building legislation. Ordinary plumbing work should not automatically be treated as requiring Home Indemnity Insurance.
Plumbing businesses with eligible employees must also meet Workers Compensation requirements under Western Australian legislation.
Plumbers insurance may suit sole traders and plumbing businesses performing installation, replacement, repair, servicing and maintenance work on residential, commercial and industrial properties.

Insurance requirements for plumbers depend on the state or territory, the plumbing activities performed, licence held, business structure and individual project or contract conditions.
Some jurisdictions impose specific insurance requirements on licensed plumbers. For example, Victoria requires licensed plumbers to maintain insurance complying with the relevant Ministerial Orders, while Tasmania requires eligible plumbing licensees to maintain Public & Products Liability Insurance meeting prescribed limits.
Other insurance requirements may arise through building contracts, head contractors, tenders, construction sites or Workers Compensation legislation.
Public Liability Insurance is not subject to one national rule requiring every plumber in Australia to hold the same policy or limit.
However, some states impose specific insurance requirements on licensed plumbers and plumbing contractors.
In Victoria, licensed plumbers must maintain insurance complying with the relevant Ministerial Orders, including at least $5 million in Public Liability cover and additional prescribed protection for certain plumbing liabilities. An ordinary Public Liability policy may not satisfy these requirements.
In Tasmania, plumbing contractors must hold Public & Products Liability Insurance in the trading name of the business. The policy must provide at least $5 million for any one occurrence for Public Liability and at least $5 million in the annual aggregate for Products Liability. This requirement applies to plumbing contractors and does not automatically mean every employed plumbing practitioner needs a separate contractor policy.
Plumbers in other jurisdictions may also need Public Liability Insurance to satisfy licence, contract, tender or site-access requirements. The applicable conditions should be checked before starting work.
The Public Liability limit required for a plumbing business can depend on state licensing requirements, client contracts, head contractor conditions, tender documents and the type of projects being undertaken.
Common limits available in the market include $5 million, $10 million and $20 million.
Some licensing systems prescribe a minimum amount, while larger commercial or construction contracts may specify different limits. A policy must also satisfy any required wording or cover conditions, not simply the stated dollar limit.
Public Liability Insurance may respond to certain claims where negligent plumbing activities cause accidental water damage to property belonging to a customer or another third party.
For example, a claim could potentially arise if a plumbing installation fails and water escapes into another part of a client’s property, damaging flooring, cabinetry or walls.
Whether a particular incident is covered depends on the circumstances, policy wording, limits and exclusions. Gradual leaks, the cost of repairing defective plumbing work and damage to property being worked on may be treated differently by insurers.
Public Liability Insurance generally does not cover the cost of correcting faulty plumbing workmanship itself.
For example, if a plumber installs a pipe incorrectly, the cost of fixing or replacing that faulty installation may not be covered under an ordinary Public Liability policy.
However, if the faulty work results in separate third-party property damage or personal injury, the resulting claim may need to be assessed under the Public Liability policy.
Victorian licensing requirements: Victorian licence-compliant plumbing insurance includes additional prescribed cover for certain defective work liabilities. This differs from ordinary Public Liability cover and remains subject to the applicable policy and Ministerial Order.
Cover is not automatic and depends on the circumstances, policy wording, exclusions and limits.
Portable Equipment Insurance, also known as General Property Insurance, may cover eligible plumbing tools and portable business equipment against loss or damage caused by insured events.
Depending on the policy, this may include theft, fire and other insured events involving eligible power tools, pipe inspection cameras, drain cleaning equipment, testing instruments and portable plumbing machinery.
Limits, security requirements, insured events and exclusions vary between policies. Theft from vehicles or unsecured locations may be subject to additional conditions.
Personal Accident and Illness Insurance may provide weekly benefit payments if an insured injury or illness prevents a self-employed plumber from working and the claim meets the policy requirements. Illness benefits apply only where illness cover has been selected.
Weekly benefits may be limited to a percentage of pre-disability earnings and a maximum insured amount. Waiting periods, benefit periods, medical evidence requirements, definitions of disablement and exclusions apply. Benefits do not necessarily replace full earnings.
This cover is separate from Workers Compensation Insurance.
Plumbing businesses with eligible employees may have Workers Compensation obligations under the relevant state or territory scheme.
Workers Compensation is separate from Public Liability and Personal Accident & Illness Insurance.
Worker definitions can also extend beyond standard full-time employees in some circumstances, so businesses using apprentices, casual plumbers, labourers or subcontractors should check the applicable scheme rules.
Portable Equipment Insurance, also known as General Property Insurance, is designed for eligible portable business property that may be taken away from the main business premises as part of normal work.
For a plumber, this may include eligible power tools, pipe press equipment, drain cleaning machinery, inspection cameras and other portable tools transported between home, vehicles, workshops and job sites.
The circumstances in which equipment is insured, including theft from vehicles, depend on the relevant policy terms, security conditions, limits and exclusions.
A Business Insurance Package can combine Public & Products Liability, where selected, with property, equipment, financial and other business covers.
Depending on the policy, optional sections can include Building, Business Interruption, Contents, Electronic Equipment, Portable Equipment / General Property, Employee Dishonesty, Employment Practices Liability, Glass, Goods in Transit, Machinery Breakdown, Money, Statutory Liability, Tax Audit and Theft.
The available options depend on the insurer and policy. Not all sections are automatically included, and some may need to be arranged separately.
A Certificate of Currency is evidence that an insurance policy is current on the date shown.
Clients, builders, principal contractors, construction companies, tender authorities and other organisations may request a Certificate of Currency as evidence that a plumbing contractor holds Public Liability or another insurance policy.
For licensed plumbers, a Certificate of Currency may also be required to demonstrate compliance with applicable insurance conditions.
A Certificate of Currency does not, by itself, confirm that every plumbing activity or contractual requirement is covered. The policy wording and any required licence-specific insurance conditions must also be considered.
You should review your insurance at renewal and whenever your plumbing business changes. This helps ensure the activities and circumstances disclosed to the insurer still reflect the work being performed.
