What Is Public Liability Insurance?

Public liability insurance is a commercial insurance policy that protects you financially if your business activities cause injury to a third party or damage to someone else's property. If a client, bystander, or member of the public makes a compensation claim against you, your policy steps in to cover the legal defence costs and any compensation payout.

For tradies — electricians, plumbers, builders, painters, landscapers, concreters and every other trade — public liability insurance is the single most important policy you can hold. You are working in clients' homes, on commercial sites, and in public spaces every day. The risk of an accident is real, and even a single uninsured claim can destroy a business financially.

A real-world example: A plumber replaces a hot water system. Water leaks from a poorly secured fitting overnight, flooding the client's kitchen and damaging their cabinetry, flooring and appliances. The repair bill comes to $45,000. Without public liability insurance, that cost falls entirely on the plumber. With insurance, the policy covers the claim less the excess.

Public liability is different from other business insurance products. It does not cover your own injuries, your tools, your vehicle, or errors in your professional advice — those require separate policies. It covers the risk you pose to others.

Is Public Liability Insurance Legally Required for Tradies?

Under federal law, public liability insurance is not mandatory for most tradespeople in Australia. There is no single national law that requires you to hold it simply because you operate a trade business.

However, in practice it is effectively compulsory for the following reasons:

  • Licencing requirements: Several states and territories require public liability cover as a condition of holding a contractor's or builder's licence. Queensland, Victoria and NSW all have minimum insurance requirements tied to certain licence classes.
  • Principal contractor requirements: On most commercial and government construction sites, the principal contractor will refuse access unless you can provide a current Certificate of Currency showing at least $5 million or $10 million in public liability cover.
  • Client contracts: Increasingly, residential and commercial clients include mandatory insurance requirements in their contracts before signing a work order.
  • Council and government work: Local councils performing tenders or engaging contractors almost universally require $10–$20 million in public liability cover.
  • Franchisors and networks: If you operate under a franchise or trade network, minimum insurance requirements are typically written into your franchise agreement.

Bottom line: Even if it is not legally required in your specific trade and state, operating without public liability insurance is a significant business risk and will shut you out of most commercial work. The question is not really "do I have to?" — it is "can I afford not to?"

How Much Cover Do You Need? ($5M, $10M, $20M)

Public liability policies are sold in standard coverage tiers. Choosing the right level depends on the type of work you do and what your clients or contracts require.

$5 Million: The minimum coverage level. Suitable for sole traders doing residential work — painting, tiling, landscaping, minor maintenance. Most residential clients accept $5M. This is the entry-level standard across most of Australia.

$10 Million: The mid-tier level. Required by most commercial sites, subcontractors working under larger builders, government-related work and local council contracts. Recommended for electricians, plumbers, and general builders working across both residential and commercial projects.

$20 Million: The higher tier. Required for large commercial or infrastructure projects, government contracts, and work in high-risk environments. Larger construction companies, concreters and civil contractors frequently need this level. Note that the premium increase from $10M to $20M is usually modest — sometimes only $50–$150 more per year.

When comparing quotes, always check the policy excess alongside the coverage limit. A policy with a $2,500 excess on every claim may appear cheaper than one with a $500 excess, but a series of small claims will quickly erode the apparent saving.

Average Cost of Public Liability Insurance by Trade (2026)

Insurance premiums are calculated based on trade type, annual turnover, geographic location, claims history, and coverage level. The figures below represent indicative annual premiums for a sole trader or small business with $5–$10 million coverage and modest annual turnover (under $500,000). Larger operations or higher-risk trades will attract higher premiums.

Electrician
$400 – $800 /yr
Higher risk classification due to electrical hazards
Plumber
$400 – $700 /yr
Water damage risk drives mid-range premiums
Builder / Carpenter
$600 – $1,500 /yr
Widest range due to variation in project size
Painter
$300 – $600 /yr
Lower-risk trade; among the cheapest to insure
Landscaper
$350 – $700 /yr
Equipment and property damage risks factored in
Concreter
$500 – $900 /yr
Structural risks push premiums above average
General Tradie
$300 – $800 /yr
Depends heavily on trade mix and turnover
Tiler / Floor Layer
$350 – $650 /yr
Relatively lower risk classification

Factors That Affect Your Premium

  • Annual turnover — higher revenue usually means higher premiums as insurers consider you take on more work and therefore more risk
  • Trade type — trades with greater property damage or injury potential (e.g. roofing, demolition) pay more than lower-risk trades (e.g. painting)
  • Number of employees and subcontractors — each additional person on your crew adds to your risk exposure
  • Claims history — a history of claims will increase your premium at renewal; a clean record can earn you discounts
  • Location — metropolitan areas typically attract slightly higher premiums than regional areas
  • Coverage limit — stepping up from $5M to $10M typically adds 15–25% to the premium
  • Excess level — choosing a higher excess lowers your premium

Tax tip: Public liability insurance premiums are generally tax-deductible as a business expense for sole traders, partnerships and companies operating in Australia. Consult your accountant to confirm eligibility for your specific structure.

What Does Public Liability Insurance Cover?

✓ What IS Covered

  • Third-party personal injury (a client, visitor or bystander)
  • Third-party property damage (client's home, vehicle, belongings)
  • Legal defence costs if you are sued
  • Compensation payouts ordered by a court
  • Medical expenses for an injured third party
  • Damage caused by products you supply or install (products liability, often included)
  • Advertising liability in some policies
  • Costs of investigating a claim

✗ What Is NOT Covered

  • Your own injuries or illness (income protection or personal accident cover)
  • Damage to your own tools and equipment (tool insurance)
  • Your work vehicle (commercial motor vehicle insurance)
  • Claims by your own employees (workers compensation)
  • Faulty workmanship or defective work product
  • Professional advice errors (professional indemnity)
  • Intentional damage or criminal acts
  • Asbestos-related claims (usually excluded)
  • Pollution claims (unless sudden and accidental)
  • Contractual liability beyond what you'd have at common law

Understanding the exclusions in your specific policy is just as important as understanding what is covered. Always read the Product Disclosure Statement (PDS) carefully and ask your insurer or broker to explain any exclusions that may be relevant to your trade before you sign.

Other Insurance Tradies Should Consider

Public liability insurance is your foundation layer, but a complete insurance programme for a tradie typically includes several other policies. Think of them as the different panels of a safety net — each one catches a different type of risk.

Tools & Equipment

Covers theft, accidental damage or breakdown of your tools and gear — on-site, in transit or stored overnight in your vehicle.

Income Protection

Replaces a portion of your income (typically 70–85%) if you cannot work due to illness or injury. Critical for sole traders with no employer safety net.

Personal Accident Cover

Pays a lump sum or weekly benefit if you are injured in an accident. Often cheaper than full income protection and can be purchased as a standalone policy.

Workers Compensation

Legally required in all states and territories if you employ workers. Covers your employees' injuries and lost wages. See our workers comp guide.

Professional Indemnity

Covers claims arising from advice, design or specification errors. More relevant to building designers, project managers and trades with a consulting element.

Commercial Vehicle

Covers your work ute, van or truck. A personal car insurance policy typically does not cover commercial use, so a dedicated commercial vehicle policy is essential.

Contract Works Insurance

Also known as builders' risk insurance, this covers loss or damage to a construction project during the build phase — fire, storm, vandalism, and more.

Business Interruption

Covers lost income and ongoing fixed costs if a covered event (fire, flood) prevents you from operating. Less common for solo tradies but relevant for larger operations.

Not sure which policies apply to your trade? Many of the comparison platforms listed in this guide (BizCover, Trade Risk) offer bundled tradie insurance packages that combine public liability, tool insurance and personal accident cover in a single policy — often at a discount to buying separately.

How to Choose the Right Public Liability Policy

With dozens of insurers competing for tradie business, selecting the right policy requires more than just accepting the lowest premium. Work through the following checklist before committing.

1. Confirm the Coverage Limit You Need

Review your current contracts and any tender documents to identify the minimum coverage limit you are required to carry. If you work across residential and commercial projects, $10 million is a safe default. If you only do residential jobs, $5 million may suffice.

2. Read the Exclusions

Every PDS contains exclusions. Common exclusions that catch tradies out include: work at heights above a certain threshold, underground services, asbestos disturbance, structural waterproofing, and work in certain building types. Make sure your normal day-to-day activities are not excluded.

3. Understand the Excess Structure

The excess is the amount you pay on each claim before the insurer covers the rest. A higher excess = lower premium, but be honest with yourself about cash flow. If you could not easily find $2,000 for an excess, do not choose a policy with a $2,000 excess just to save $80 per year on the premium.

4. Check the Claims Process

A cheap policy from an insurer with a poor claims process can be worse than a slightly more expensive policy from a responsive insurer. Look at reviews, particularly regarding claims handling. Industry-specific brokers (like Trade Risk) often provide dedicated claims support.

5. Compare at Least Three Quotes

Prices for the same coverage level can vary by 30–50% between insurers for identical trade types. Use comparison platforms or brokers to get multiple quotes quickly. The providers listed below are all worth checking.

6. Look for a Tradie-Specific Policy

Generic small business public liability policies may not be tailored to the specific risks of your trade. Tradie-focused policies (available through BizCover, Trade Risk and similar) are usually more appropriate and may include additional features relevant to tradespeople.

7. Check Retroactive Cover

If you have been operating without insurance and are now buying your first policy, check whether a retroactive date applies. Some insurers can cover claims arising from work performed before the policy start date — this can be valuable if a client raises an issue months after a job is complete.

How to Get a Public Liability Quote — Step by Step

Getting a quote online is straightforward. Here is what to have ready before you start, and what to expect at each step.

1

Gather Your Business Details

You will need your ABN, business structure (sole trader, company, partnership or trust), and the full name under which you trade.

2

Identify Your Trade Type

Select your primary trade from the insurer's list. If you perform multiple types of work (e.g. carpentry and tiling), disclose all activities — undisclosed activities may void a claim.

3

Estimate Your Annual Turnover

This is your gross revenue for the year, not your profit. Be accurate — significantly understating turnover can give grounds for an insurer to reduce or reject a claim.

4

Advise Number of Workers

State how many full-time, part-time and subcontractor employees work under your direction. Remember that subcontractors should ideally carry their own cover.

5

Select Coverage Limit and Excess

Choose $5M, $10M or $20M based on your contract requirements. Then choose an excess that balances affordability of premium against the amount you could realistically pay in the event of a claim.

6

Disclose Any Prior Claims

Most insurers ask about claims in the previous three to five years. Be honest — non-disclosure is grounds for a policy to be voided at the worst possible time.

7

Review the PDS Before Paying

Read the Product Disclosure Statement — even the sections that seem dry. Pay particular attention to the exclusions and conditions. If anything is unclear, call the insurer or broker before purchasing.

8

Download Your Certificate of Currency

Once you have purchased your policy, immediately download or request a Certificate of Currency. This is the document clients and principal contractors will ask you to produce. Keep a digital copy on your phone at all times.

Frequently Asked Questions

Is public liability insurance mandatory for tradies in Australia?
Public liability insurance is not legally mandatory under federal law in most trades in Australia, but it is practically essential. Most principal contractors, construction sites, councils and commercial clients require proof of at least $5 million cover before allowing you on site. Some state licencing bodies require it as a condition of your contractor's licence.
How much does public liability insurance cost for a tradie?
Costs vary by trade and coverage level. General tradies typically pay $300–$800 per year. Electricians pay $400–$800, plumbers $400–$700, builders $600–$1,500, painters $300–$600, landscapers $350–$700, and concreters $500–$900 per year for $5–$10 million in coverage.
What does public liability insurance cover for tradies?
Public liability insurance covers third-party personal injury claims, third-party property damage, and associated legal defence costs. For example, if a client trips over your equipment and is injured, or you accidentally damage a client's property during a job, your policy covers compensation and legal expenses.
What does public liability insurance NOT cover?
Public liability does not cover your own injuries or illness (you need income protection or personal accident cover), damage to your own tools and equipment (tool insurance covers this), faulty workmanship or defective work product, or claims from your own employees (workers compensation covers this).
How much public liability cover does a tradie need?
The most common levels are $5 million, $10 million and $20 million. Most residential clients and small commercial projects require $5 million minimum. Government contracts, large commercial sites and some councils require $10–$20 million. Always check your contracts before choosing a limit.
Can I get public liability insurance for just one job?
Yes. Some insurers offer short-term or single-project public liability policies. Providers like BizCover and Trade Risk offer flexible policy terms. However, an annual policy is usually more economical if you work regularly.
Does public liability insurance cover subcontractors working for me?
Generally your policy covers your own operations. Subcontractors should carry their own public liability insurance. If a subcontractor causes damage while working on your job, your insurer may seek to recover costs from their policy. Always verify that subcontractors hold current cover.
Which is the best public liability insurance provider for tradies in Australia?
There is no single best provider — the right choice depends on your trade, annual turnover and risk profile. BizCover and Trade Risk are popular for their ease of online quoting and competitive pricing for sole traders. For larger contractors, brokers like Aon or CGU may offer broader coverage. Comparing at least three quotes is recommended.
What information do I need to get a public liability insurance quote?
You will typically need: your trade type and licence number, your business structure (sole trader, company, partnership), your estimated annual turnover, number of employees or subcontractors, the states you operate in, and any claims history from the past five years.
