TL;DR
If you get paid to give advice, deliver professional services, or create work that clients rely on to make decisions, you need professional indemnity insurance. One disputed project, one unhappy client, one allegation of negligence, even one you’d win, can generate high legal costs before a resolution is reached. PI insurance is what keeps that from ending your business.

What is Professional Indemnity insurance?
Professional indemnity (PI) insurance protects your business against claims that your professional advice, services, or work caused a client financial loss. If a client alleges you made an error, missed a deadline, gave negligent advice, or breached their confidentiality and sues you for it, PI insurance covers your legal defence costs, investigation fees, and any compensation you’re found liable to pay.
Unlike public liability, which responds to physical injury or property damage, professional indemnity responds to financial harm. It’s the cover that sits behind everything you create, recommend, or advise professionally.
Key facts
- Legal defence costs for a disputed professional negligence claim can be significant even when you’re not found liable, responding to a claim properly requires legal representation, expert witnesses, and time. PI insurance covers those costs regardless of the outcome.
- Professional indemnity is compulsory (depending on which state you’re registered in and your professional memberships) for certain regulated professions in Australia, including financial advisers, accountants, lawyers, architects, engineers, and registered migration agents
- PI insurance is written on a “claims made” basis meaning you need cover in place when the claim is made, not just when the work was done. Letting your policy lapse leaves all past work unprotected.
- A limitation of liability clause in your contract does not eliminate PI exposure. Courts can override these clauses, and you still need to pay for your defence regardless
- The number of professional negligence claims in Australia has increased significantly as clients become more commercially sophisticated and litigation more accessible
What does professional indemnity insurance cover?
PI insurance responds when a client claims that something you did or didn’t do in a professional capacity caused them financial loss. The scenarios are broader than most founders expect:
| Claim type | Example |
|---|---|
Professional negligence | A business consultant’s restructuring advice leads to losses; client sues for $200,000 |
Error or omission | An accountant miscalculates a tax position; the client faces a penalty |
Missed deadline | A marketing consultant delivers a campaign 3 weeks late; client claims $80,000 in missed peak-season revenue |
Breach of confidentiality | A developer accidentally exposes proprietary client code publicly; client claims competitive damage |
Misleading advice | A financial planner recommends a strategy that underperforms; client alleges the advice was unsuitable |
Intellectual property infringement | A designer’s work inadvertently uses protected elements; third party makes a claim |
Defective work product | A software build contains errors that cause the client’s system to fail during a critical period |
What the policy actually pays:
Legal defence costs, usually the largest single cost item in any PI claim
Court costs and settlements
Compensation payments for client losses where you’re found liable
Costs to correct or redo defective work
Investigation costs and expert witnesses
Your legal representation throughout the process
What professional indemnity insurance doesn't cover
Understanding the exclusions is just as important as knowing what’s included:
| Not covered | What covers it instead |
|---|---|
Bodily injury or property damage | Public liability insurance |
Your own business losses | Business interruption insurance |
Intentional wrongdoing or fraud | Not insurable |
Work done before cover was in place | Nothing — this is why continuous cover matters |
Criminal acts or illegal services | Not insurable |
Contractual penalties | Only if specifically included in your policy |
Employment disputes | Management liability / employment practices liability |
Cyber incidents | Cyber protection insurance (though some PI policies have limited cyber extensions) |
Understanding "claims made" cover - the critical detail
This is the single most important thing to understand about professional indemnity insurance, and the point that catches the most founders out.
PI insurance is written on a “claims made” basis. This means:
Your policy must be active at the time the claim is made, and at the time the work was performed
A project you completed two years ago is only covered if your current policy was in place when the work was performed (i.e. the retroactive date predates that work) and remains active when the client makes the claim.
If you let your policy lapse, even briefly, you risk losing cover for past work. Your retroactive date, shown on your policy schedule, is the date from which your cover applies. If your policy lapses and you reinstate it, your new insurer may set a new retroactive date, which means work done before that date is no longer covered.
Why this matters in practice:
A web developer builds a site in 2024, lets their PI policy lapse in early 2025, and the client raises a negligence claim in mid-2025. The developer has no cover. The work was done while insured but the claim wasn’t made while insured.
This is fundamentally different from most other insurance products, which cover events that occur during the policy period regardless of when the claim is lodged.
Runoff cover: If you stop trading or retire, you should consider “run-off” cover — a PI extension that keeps you protected for claims arising from past work even after you’ve ceased operating. The standard period is typically six years.
Professional indemnity vs public liability: what's the difference?
The comparison that matters most for service-based business owners:
| Professional Indemnity | Public Liability | |
|---|---|---|
| What it covers | Financial loss from professional advice, errors, or services | Physical injury or property damage to a third party |
| Who claims | Client who suffered financial loss | Injured person or property owner |
| Trigger | Advice, error, omission, or service failure | Physical incident — injury, damage, accident |
| Classic example | Client loses money acting on your advice | Client trips in your office and breaks their wrist |
| Policy basis | Claims made | Occurrence-based |
| Who needs it | Anyone delivering professional advice or services for a fee | Almost any business with physical interaction with clients or public |
| Legally required? | Compulsory for some regulated professions | Not generally, but required by most leases and contracts |
Do you need both? For most service businesses: yes. A consultant who meets clients in their office has public liability exposure (physical incidents on premises) and professional indemnity exposure (the work they deliver). They’re not interchangeable.
Who needs professional indemnity insurance?
Compulsory by law or regulation
PI is a legal requirement for certain professions in Australia. These include:
Financial advisers – required under the Corporations Act and ASIC licensing conditions
Accountants and tax agents – required under Tax Practitioners Board registration
Lawyers – required by state and territory law societies
Architects – compulsory in most Australian states and territories
Engineers – required for registration in several states
Registered migration agents – compulsory under the Migration Agents Registration Authority
Healthcare professionals – varies by registration board; most AHPRA-registered practitioners are required to hold cover
If your profession is regulated, or you hold a professional membership, check your licensing conditions before assuming you’re covered. Gaps here can affect your registration, not just your insurance position.
Strongly advisable for
Even where it’s not legally required, PI is strongly advisable for any business that:
Gives advice, recommendations, or strategic guidance clients act on
Designs, builds, or creates work clients rely on commercially
Handles sensitive or confidential client information
Works under contracts that specify PI requirements (increasingly standard in corporate and government procurement)
Has clients who could suffer significant financial loss if the work goes wrong
This includes: consultants of all kinds, designers, developers, marketers, IT service providers, HR consultants, coaches, project managers, copywriters, engineers, surveyors, and event managers.
A note on “I’ve never been sued”
Most founders and business owners who’ve never faced a PI claim use it as evidence they don’t need cover. It’s the wrong frame. The relevant question is: could a client claim financial loss from your work? If yes, the exposure exists regardless of whether anyone has acted on it yet.
How much professional indemnity cover do you need?
Cover limits vary depending on your profession, the nature of your work, and your contractual obligations. $1–2 million is a common entry point for solo operators, while $2–5 million is increasingly standard for growing consultancies and agencies. Corporate and government contracts frequently specify $5–10 million as a minimum.
That said, the right limit depends on your specific circumstances, particularly the size of your largest project and what your client contracts require. We’d recommend speaking with a broker who can review your contracts, licensing conditions, and risk profile before you settle on a limit.
How to determine your minimum:
Check your client contracts – most corporate and government contracts specify a minimum PI limit, often $5–10 million
Check your licensing or registration conditions if you’re in a regulated profession
Consider the size of your largest project or engagement and what a client could realistically claim if things went wrong, this is a useful starting point for a conversation with your broker.
Consider your industry’s claim history – financial advice, legal services, and construction-adjacent roles attract larger claims on average
The most common mistake is setting limits based on what feels comfortable rather than what your actual exposure requires. A $2 million limit on a $3 million project is a gap.
What does professional indemnity insurance cost in Australia?
Professional indemnity premiums vary significantly based on profession, revenue, claims history, coverage limit, and the complexity of your work all influence the figure. The range is wide enough that any indicative number would be misleading for your specific situation.

What affects your professional indemnity premium?
Factors that increase premium:
Higher annual revenue or fee income
High-risk profession (financial advice, legal, construction-adjacent)
History of prior claims or notifications
Working with large corporate or government clients
Complex, high-value project work
Multiple staff delivering professional services
Factors that reduce or stabilise premium:
Clean claims history
Strong engagement documentation – clear contracts, scope agreements, written advice
Lower coverage limit (though calibrate this against actual exposure)
Consistent, long-term relationship with your insurer or broker
Demonstrated risk management practices (engagement letters, documented processes)
What you can control: Your documentation. Insurers price on risk, and businesses with tight engagement processes. Clear scope, written sign-off, documented advice present a more manageable risk profile. This is worth doing for its own sake, and it affects your premium over time.
By founder stage
Start smart: pre-launch to year one
You need PI from day one if you’re delivering any professional service for a fee. Don’t wait for a client to require it, the exposure begins with your first engagement.
Priority actions at this stage:
Confirm whether your profession requires PI under any licensing or registration condition
Check your first client contract for specified PI limits before signing
Get engagement letters in place from the start, they protect you and make your insurance position cleaner
Typical coverage: $1–2 million for solo operators. If your first client contract specifies a higher limit, match it.

Scale strong: growing and hiring
As your revenue grows and your clients get larger, your PI exposure grows with them. A $200K project with a corporate client carries more PI risk than ten $20K projects with small businesses.
Review your cover when:
Your revenue exceeds $1 million
You’re taking on corporate or government clients with contract PI requirements
You’re adding staff who deliver professional services (their work is your liability)
You’re expanding into new service areas with different risk profiles
Typical coverage: $2–5 million. Some corporate contracts require $5–10 million — check before you sign.
Guide: What changes when you hire your first employee
Stay protected: established and optimising
At this stage the risk isn’t being uninsured, it’s being under-insured as your business has evolved, or having gaps from past work you’ve forgotten about.
Review your cover if:
You’ve changed your service offering since you last renewed
You’ve had a client complaint or near-miss that didn’t escalate, notify your insurer regardless
A client has threatened action, even informally, notify immediately
You’re considering winding down or retiring (run-off cover)
Your premium has jumped significantly at renewal without explanation
Important: If a client threatens a claim (even in a passing email) notify your insurer promptly. Late notification can affect your cover. When in doubt, notify.
Typical coverage: $5–20 million depending on industry and contract requirements. Broker guidance is essential at this stage.

Frequently asked questions
1. Is professional indemnity insurance compulsory in Australia?
It is legally compulsory for certain regulated professions. But this depends on the type of professional membership you hold and which state you operate out of. Financial advisers, accountants, lawyers, architects, engineers, and registered migration agents, among others fall into this category. For non-regulated professions, it’s not legally required but is increasingly required by client contracts, government procurement, and professional association membership. For anyone delivering professional services for a fee, the practical case for having it is strong regardless of the legal position.
2. What is “claims made” insurance and why does it matter?
Claims made means your policy must be active when the claim is lodged, and just when the work was performed. If you cancel your PI policy and a former client makes a claim six months later, you have no cover, even if you were insured when you did the work. This is why PI coverage should be maintained continuously for as long as past work could theoretically generate a claim and why run-off cover matters when when you stop trading or your business services change.
3. Does my contract’s limitation of liability clause protect me?
It helps, but it doesn’t eliminate the risk. Courts can override limitation clauses if they’re found to be unfair or unreasonable. More practically, even a defensible limitation clause doesn’t prevent a client from suing — and you’ll need to pay for your defence regardless of what the clause says. PI insurance covers that defence cost whether your clause holds subject as always to the terms and conditions of your policy.
4. Can a client sue me personally as a sole trader?
Yes. As a sole trader, there is no legal separation between you and your business. A successful claim against your business is a claim against you personally — which means your personal assets, including savings, property, and vehicles, are exposed. Even as a company director, personal liability can apply in certain circumstances. PI insurance protects your personal position as well as your business.
5. What happens if I get a complaint but it hasn’t become a formal claim yet?
Notify your insurer as soon as you become aware of a circumstance that could give rise to a claim even if no formal claim has been made. Most PI policies require prompt notification of potential claims, not just actual ones. Delayed notification can affect your cover. If a client expresses dissatisfaction in a way that suggests they might pursue action, treat it as a notification event.
6. Do I need PI insurance if I use a contract with clear terms?
Contracts are your first line of defence. They define scope, set expectations, and limit liability where possible. But a contract doesn’t prevent a client from suing you, and it doesn’t pay for your legal defence while the dispute is resolved. PI insurance and a well-drafted contract work together; one doesn’t substitute for the other.
7. How do I know if my existing PI policy has the right coverage for my business?
The most important check: does your coverage limit meet or exceed the requirements in your client contracts and licensing conditions? Beyond that, review whether your policy covers all the service types you deliver — adding new services (e.g. moving from implementation to advice, or expanding into a new discipline) without notifying your insurer can create coverage gaps. An annual broker review catches these issues before they matter. But if you add new services, take on a significant new client, or your work scope changes materially, notify your broker immediately.
8. What is run-off cover and do I need it?
Run-off cover is a PI extension that protects you against claims arising from past work after you’ve stopped trading or retired. Because PI is claims made, ceasing to operate without run-off cover leaves all your past work unprotected. Standard run-off periods are typically six years — aligning with general limitation periods under Australian contract law. If you’re winding down or selling your business, run-off cover is worth discussing with your broker.
