Professional Indemnity Mechanics: Navigating Claims-Made Policies, Retroactive Dates, and Run-Off Cover

Simplified Professional Indemnity Policy Matrix
Policy Structure
Professional Indemnity (PI) insurance operates differently from some other commercial insurance products. While Public Liability or Property insurance focuses on when an incident occurs, Professional Indemnity operates around when a claim or circumstance is first discovered and reported to the insurer.
Understanding these mechanics is critical. It’s not unusual for coverage disputes to arise because the policyholder misunderstands claims-made triggers, retroactive dates, and notification requirements.
Key Concepts To Understand
Claims-Made vs. Occurrence
One of the most important concepts in insurance is the distinction between claims-made and occurrence-based cover. Professional Indemnity Insurance operates on a claims-made basis, which means the current policy in force will respond to a claim notified.
For example:
- An architect made a mistake in 2024, but is unaware until 2026.
- If PI remains continuously in force, the current policy may respond.
- If cover lapses before the claim arises, there will be no protection.
Retroactive Date
The retroactive date refers to the specific date from which coverage begins. It is called a retroactive date because it extends protection for services provided before the policy's inception date, which will typically renew every 12 months.
A claims-made policy needs a mechanism to determine how far into the past protection extends. It is an important consideration to ensure protection is still available for work undertaken in the past.
Run-Off Cover
Your exposure to claims does not necessarily end when a business ceases trading. Clients may discover errors years after a project has been completed, particularly in sectors such as:
- construction
- engineering
- architecture
- legal services
- financial advice
- technology services
Given PI Insurance operates on a claims-made basis, protection for historic work disappears if there is no active policy available to notify the claim. Run-Off Cover also known as an extended reporting period provides an extension to the policy period to notify claims.
The Duty of Notification
The claims-made structure of PI insurance places significant importance on reporting the issue to the insurer as soon as reasonably practicable.
A common misunderstanding is that insurers only need to be notified when a formal legal claim arrives. Whilst most policies require notification of any circumstance that may give rise to a claim.
Examples may include:
- client complaints
- project failures
- allegations of poor advice
- contractual disputes
- known errors
- regulatory investigations
- significant service failures
A circumstance does not need to be certain to become a claim. The threshold is usually whether a reasonable professional would recognise the possibility of future allegations.
Failure to notify a known circumstance can create serious coverage issues and may result in a later claim being declined. When in doubt, seek advice from your broker and consider notification as a matter of prudence.
Policy Tiggers and Scope of Coverage
Civil Liability vs. Negligence Wordings
Historically, PI policies were provided on a negligence only basis. These policies required the claimant to allege professional negligence before cover would be granted under the policy.
Modern policies today will in the vast majority of cases use a broader civil liability wording, which may respond to claims arising from:
- negligence;
- breach of professional duty;
- breach of confidentiality;
- intellectual property infringement;
- defamation;
- breach of contract; and
- other civil causes of action.
A civil liability wording is designed to respond to a wider range of allegations. The practical difference can be significant because most client allegations arise from a breach of contract.
Vicarious Liability
Professional service firms increasingly rely on subcontractors, consultants, and third-party service providers. However, from a client's perspective, the responsibility for the provision of their service will remain with the company they are contracted to, not the third-party which they don’t have a contractual relationship with.
This creates vicarious liability, where a business can be held legally responsible for the negligent acts, errors, or omissions of those acting on its behalf. For example, a technology company may use external developers to complete a software implementation. If the subcontractor's work causes a financial loss to the client, the claim will most often be directed at the principal contracting party, not the subcontractor, no matter where responsibility rests.
Not all policies provide vicarious liability as standard and cover can be restricted. Speak to your broker to understand whether you have sufficient protection in place?
