1. What Is Professional Indemnity Insurance?
Definition: Professional indemnity insurance is a form of business liability insurance that protects professionals who provide advice, expertise, or services to clients. It covers legal costs and compensation claims if a client alleges you’ve made a mistake, acted negligently, or breached professional duty.
Key point: Unlike general liability insurance, which covers physical injury or property damage, PII focuses on financial losses due to professional work.
1.1 How It Works
When a client claims that your professional service caused them financial harm — whether through incorrect advice, design flaws, or missing deadlines — they may sue you for damages. PII will typically cover:
-
Legal Defense Costs – Lawyer fees, court costs, and expert witness fees.
-
Compensation Payments – If you are found liable, the policy pays out to cover damages.
-
Settlements – Payments made to avoid prolonged legal battles.
1.2 Common Industries Requiring PII
Professional indemnity insurance is essential for professionals such as:
-
Accountants and auditors
-
Architects and engineers
-
Consultants (business, IT, marketing, etc.)
-
Solicitors and legal advisers
-
Surveyors and real estate professionals
-
Healthcare practitioners (specialist coverage)
-
Designers (graphic, interior, industrial)
-
Technology service providers and software developers
2. Why Professional Indemnity Insurance Is Important
2.1 Protecting Your Reputation
A lawsuit, even if unfounded, can damage your professional image. PII helps you defend your reputation while covering costs.
2.2 Meeting Legal or Contractual Requirements
Some professional bodies, regulators, and clients require PII before you can work with them. For example:
-
UK solicitors must have a minimum PII limit set by the Solicitors Regulation Authority.
-
In Australia, architects and engineers often need PII to maintain their professional licenses.
-
Many corporate contracts require proof of PII before engagement.
2.3 Financial Security
Litigation can be expensive. Without insurance, defending even a minor claim could cost tens of thousands — potentially bankrupting a small business.
3. What Does Professional Indemnity Insurance Cover?
While each policy is different, typical coverage includes:
-
Negligence – Failing to exercise the appropriate skill and care.
-
Errors or Omissions – Forgetting a key element or making a factual error.
-
Breach of Duty – Failing to meet a contractual or legal obligation.
-
Misrepresentation – Providing false or misleading information (unintentionally).
-
Intellectual Property Infringement – Using copyrighted work without permission.
-
Defamation – Libel or slander occurring during professional work.
-
Loss of Documents or Data – Losing client files or sensitive information.
Example
A marketing consultant develops a campaign for a client, but due to a misinterpretation of regulations, the ads are pulled, costing the client $100,000 in lost revenue. The client sues for negligence — PII covers the legal defense and settlement.
4. What Isn’t Covered?
Professional indemnity insurance has exclusions. Common ones include:
-
Deliberate acts, fraud, or criminal activity
-
Bodily injury or property damage (covered under general liability insurance)
-
Employment disputes (covered by employment practices liability insurance)
-
Known claims before the policy started
-
Contractual liabilities that go beyond normal professional duty
5. Claims-Made vs. Occurrence Policies

-
The claim must be made during the policy period.
-
The incident must also have occurred after the retroactive date on the policy.
If your policy lapses, you may lose coverage for past work unless you buy run-off cover.
