What Is Professional Indemnity Insurance?

Professional indemnity insurance may help protect businesses and professionals when a client claims their advice, designs or services caused financial loss. It may include cover for legal defence costs and any compensation awarded, subject to policy terms. It is often shortened to PI insurance and can also be called Errors and Omissions or Professional Liability insurance.

Key takeaways

• Cover generally operates on a claims-made and notified basis, so timing and notification matter as much as the work itself. 
• What is a claims made policy? This means that the claim is triggered in the period of insurance when a letter of demand, suit or civil claim is made against you, not when the services are performed.

• This makes concepts like retroactive date, and continuous cover really important to consider to ensure that you may always be covered for your services and a claim that could be brought against you for  your services - even after you stop running your business this can be called ‘run off’ cover. 

• The retroactive date sets how far back a policy may reach for past services or work that you performed, giving you extra certainty that prior services would be covered even if the claim is made in your current policy period, though it does not by itself confirm a claim is covered.
• Defence costs may sit inside or outside your limit, which changes what is left for the claim settlement payment or any damages payment itself.
• It is not required by law for most Australian businesses, but registration bodies and client contracts often require professional indemnity insurance.
• Run-off cover continues claims-made protection for past work after you stop trading or after your business is sold.

Professional indemnity insurance at a glance

Who should buy PI insurance?

It’s important that you consider whether you are a services based business or a products based business. Do clients rely on your designs or professional services and advice? If an error could cause them a material financial loss, this cover is worth serious consideration, even where no law requires it. Defence costs are part of the reason. Responding to a civil claim does not have to succeed to cost you money.

Who should consider professional indemnity insurance?

Any business paid for advice or professional services carries this exposure. Insurer definitions of professional services vary, so the practical test is simpler: do clients rely on your skills, knowledge or judgement to make decisions?

Four groups arrange it most often.

Professional and business services: consultants, accountants, bookkeepers, marketing and advertising specialists, recruiters and financial advisers.

Design and construction: architects, engineers, surveyors, draftspeople and interior designers, where a design error can carry very large costs.

Technology: software developers, IT contractors, managed service providers and cybersecurity specialists, whose work sits inside client systems.

Health and wellbeing: allied health practitioners, therapists and specialist advisers.

It also catches people who do not think of themselves as professionals. A tradesperson who gives design advice, or a fitness instructor who writes training programs, may both be delivering a professional service alongside physical work.

Do sole traders need professional indemnity insurance?

Yes, sole traders may need to consider taking out this type of insurance if they provide advice related services. Sole traders sit in the same position as larger firms. The size of the business does not change the size of a client's loss. A single consultant advising on a large project can face a claim well beyond their annual turnover, with no company structure in between.

Contractors and freelancers are worth a separate mention. Where you work through a client's business, their insurance may not extend to your professional work. That is why many contracts require you to hold your own before the engagement starts.

Working out what a sole trader business needs overall? Professional services insurance usually means this cover plus public liability, since most client contracts ask for both.

What does professional indemnity insurance respond to?

PI insurance is designed to respond to claims arising from your professional services. This can include: 

• Negligence and errors. Claims that your work fell below the expected standard and caused a financial loss.
• Omissions. Claims that you failed to provide advice or information a client needed.
• Misleading advice. Claims that inaccurate advice was relied on, to the client's cost.
  

What does professional indemnity insurance cover? 

• Legal costs. Investigating and defending a claim, including claims that turn out to have no merit, subject to policy terms.
• Settlement or financial damages. This covers payments to the client where agreement is reached for an amount to cover the alleged loss or damage and is typically put forward by your lawyer.

Several further features are commonly available but policy-dependent, so check whether your wording includes them:

• Breach of confidentiality
• Intellectual property infringement
• Defamation
• Loss of client documents
• Statutory liability, where offered

Some policies, particularly for allied health and design occupations, may also extend to bodily injury or property damage arising from professional services. Others exclude it. This is one of the biggest differences between wordings, so read it rather than assuming.

What does professional indemnity insurance not cover?

Every policy has limits, and it helps to separate three different things: exclusions, limitations and other classes of insurance.

Common exclusions include fraud, dishonesty and deliberate wrongdoing, along with fines and penalties that cannot be insured at law. Prior known circumstances matter too. Illegal acts, sexual abuse or motor vehicle claims are also typically be excluded from standard policies. This is because motor insurance should respond to accident claims. Sexual abuse is a bespoke cover that is expensive so not ordinarily covered in a standard policy. Anything you were already aware of before the policy started is generally excluded.

Limits of Liability  work differently. A sub-limit means the loss is covered but capped below your main limit. Conditions may require you to notify claims within a set time, or to answer proposal questions accurately. Missing one can affect a claim even where no exclusion applies.

Other classes of insurance cover different exposures. Claims about injury to people or damage to property usually fall within a public liability insurance policy. As noted above, some professional policies do extend to injury arising from professional services. If you’re interested in accidents or injuries to yourself being covered this might be a personal accident insurance policy.

How does professional indemnity insurance work?

PI insurance behaves differently from most business insurance, and four features decide whether you are actually protected.

Claims-made and notified cover

Professional indemnity generally operates on a claims-made and notified basis. In broad terms, the policy in force when a claim is made and notified is the one that may respond. It is not the policy you held when you did the work.

Several things affect this. The claim and its notification need to meet the policy's timing terms. The work generally needs to fall after the applicable retroactive date and you need to have typically held this insurance in place continuously. Prior known circumstances about the claim before you commenced insurance policy may affect whether cover is available cover, and notifying circumstances promptly can matter as much as notifying claims. Holding continuous cover helps, but it does not by itself guarantee a claim is covered. For how this differs from other covers, see claims-made versus occurrence insurance.

Retroactive dates

The retroactive date is the date from which a policy may reach back to cover past work. Work done on or after that date may be covered, and work before it generally is not.

Policies set it in different ways: your first continuous policy inception date, a specific earlier date, or unlimited retroactive cover. Unlimited cover still remains subject to exclusions, disclosure and known-circumstance provisions.

Worth checking at every renewal: a new policy schedule may show a different retroactive date from your previous one. Compare the two schedules side by side before the policy binds, and raise any change with your broker rather than after.

Run-off cover

Run-off cover is a special endorsement that applies to help ensure your cover continues to offer claims-made protection for past work even after you've stopped operating your business or sold your business. Because cover is often claims-made, a claim arriving after you stop trading has no active policy to consider it.

If you are retiring, selling the business or changing profession, ask about run-off before you cancel.

Defence costs and excesses

Some policies pay legal defence costs within your limit, so a long defence reduces what is left for the claim itself. Others pay defence costs in addition to the limit. Two policies with the same headline limit can leave you in very different positions once lawyers are involved.

Check the excess alongside it, including whether it applies to defence costs as well as settlements.

Is professional indemnity insurance compulsory in Australia?

Not for most businesses. No general law makes professional indemnity insurance in Australia compulsory. For a defined set of registered professions, appropriate arrangements are a condition of practising. That obligation usually sits in the registration standard rather than in insurance law.

Two things are worth understanding before you read the table. First, several schemes require appropriate arrangements, which is not always the same as holding an individual policy. Employees and contractors are sometimes covered through an employer's or another practitioner's cover. Second, requirements are reviewed and changed, and some are set by state rather than nationally.

This table is not exhaustive, and requirements are set by profession and sometimes by state. Check the conditions on your own registration. For state detail, see professional indemnity insurance in NSW.

For everyone else, the requirement usually arrives through a client contract, a tender schedule or a professional association's membership rules.

How much professional indemnity cover might you need?

Contracts commonly specify $1 million, $2 million, $5 million or $10 million limits of liability, depending on the size and risk of the work. Larger commercial contracts and government tenders can specify more, though the figure varies by agency and project up to commonly a $10 million or $20 million limit of liability.

Two phrases in a contract change what the limit means. "Per claim" applies the limit to each individual claim. "In the aggregate" makes it the total across all claims in the policy period. Some contracts ask for both.

Where nothing sets a figure, businesses commonly choose a limit based on the value of the work they advise on. The other question worth asking is what an error could realistically cost a client. For a fuller walk-through, see what level of professional indemnity cover you need.

Professional indemnity versus public liability insurance

The practical difference is what the allegation is about, not simply what kind of harm occurred.

Check this for more details - Professional indemnity versus public liability insurance

Some professional policies extend to injury arising from professional services, and a single incident can be framed either way depending on what the claimant alleges. Many service businesses hold both because contracts commonly require both.

In practice, most contracts that ask for one ask for both, because a single engagement can create either exposure. A consultant visiting a client site can give advice that turns out to be wrong and knock over equipment on the same afternoon.

Management liability is a different cover again, aimed at claims against directors and the business itself. See professional indemnity versus management liability insurance if you are weighing those two.

Professional indemnity claim examples

These scenarios and figures are hypothetical, written to show how claims of this kind arise. They are not upcover claims data. Whether a policy responds depends on its terms, exclusions and limits.

A design specification mistake. A designer misreads a project specification and the wrong materials are ordered. Rework and a three-week delay cost the client $40,000, which they claim from the designer.

A data handling error. An IT contractor migrating a client database loses part of the records. Reconstructing the data costs $25,000, and the client claims that plus revenue lost while data was unavailable.

Each turns on money lost because of professional work, not physical harm. Note the timing too: claims like these often arrive well after the job is finished.

What should you compare before arranging cover?

Policies that look alike on price can differ sharply in what they do. Five things are worth comparing side by side.

Who is covered? Check that the policy covers the right entity, and how employees, contractors and partners are treated. Cover often works through policy definitions rather than naming people individually.

Your business activities. The insured activities on the schedule should reflect what your business really does. If the description is too narrow, it doesn’t list all your activities or you are concerned it isn’t accurate, then you may not be covered. Speak to your broker or reach out to the team at upcover. 

The limit and how it applies. Check the amount, whether it applies per claim or in the aggregate, and whether legal costs sit inside or outside it.

The retroactive date. Confirm it reaches back to when you started doing this work, and compare it against your current schedule if you are switching. Be sure you don’t let your policy cancel so your continuity of cover and retroactive date covers all the work you have done.

Exclusions and conditions. Read what is excluded, what carries a sub-limit, and what the policy requires of you.

If a client contract sets insurance terms, read that alongside the policy before you commit. Not sure how a contract clause or a retroactive date affects you? That is worth a conversation with a broker rather than a guess on a form. For the full buying checklist and a side-by-side quote comparison, see how to choose professional indemnity insurance.

How much can professional indemnity insurance cost?

Cost depends on your profession, turnover, the limit you select and your claims history. Across policies reviewed by upcover, a typical small business paid around $1,200 a year, with most paying somewhere between around $760 and $2,100.

Frequently asked questions

Do sole traders need professional indemnity insurance?

No law requires it for most sole traders, but client contracts often do. A sole trader has no company structure separating them from a claim about their work, and the size of a client's loss does not scale down with the size of your business. Many sole trader consultants, designers and contractors arrange it because their engagements demand it.

Is professional indemnity insurance the same as professional liability insurance?

Yes, in most Australian usage. Professional liability or Errors and Omissions is the term used more often overseas, particularly in the United States. Australian policies are generally labelled professional indemnity, civil liability and sometimes shortened to PI insurance. People also search for personal indemnity insurance, which usually means the same business cover rather than a personal policy.

Is professional indemnity insurance tax deductible in Australia?

Generally, premiums may be deductible to the extent they are incurred in carrying on your business and earning assessable income. The ATO treats insurance of this kind as an operating expense in those circumstances. Your own position depends on your structure and how the policy is used, so confirm it with a registered tax agent.

Do I still need professional indemnity insurance if I work through a company?

In many cases, yes. A company structure limits personal liability for business debts, but claims about professional services may be directed at both the individual and the company, depending on the circumstances. Client contracts and registration bodies also commonly require the insurance regardless of the business structure.

What is a certificate of currency for professional indemnity insurance?

It is the document confirming your policy was current when it was issued, showing your insured name, insurer, policy number, dates and limit. Clients and tender panels ask for it as proof of cover. See what is a certificate of currency for what to check before submitting one.

Does professional indemnity insurance cover work done for overseas clients?

Sometimes, but it depends on the policy. Territorial and jurisdictional limits vary between insurers, and work performed or litigated outside Australia may fall outside cover. If you take on overseas engagements, raise it before the policy is arranged.
