Under most professional indemnity (PI) policies, four dates decide whether the policy responds to a claim: when you did the professional work, when someone made the claim against you, when you reported it to the insurer, and the policy’s retroactive date. Getting them out of step – by letting cover lapse, switching insurers carelessly or reporting late – can leave a professional uninsured for a claim they assumed the policy covered.
Law firms often frame this as a Retroactive Date legal Indemnity Insurance question – how far back does the firm’s cover reach? – but the same rules apply to chartered accountants, architects, engineers, IT consultants and other professionals. The outcome always depends on the policy’s wording, its coverage trigger, its exclusions, its notification rules and any endorsements. Indeed, PI policies don’t all work the same way.
What Is a Retroactive Date in PI Insurance?
A retroactive date marks how far back a claims-made PI policy can reach for professional work: the policy generally excludes work you did before it. Also, the claimant must make the claim, and you often must report it, during the policy period, subject to the wording. Keeping the same retroactive date at renewal or when switching insurers helps avoid gaps.
Key Takeaways
- Claims-made policies respond to claims that arise during the policy period, not to when you did the work.
- The policy generally excludes work you did before the retroactive date.
- Some wordings also require the claimant to make the claim and you to notify it during the period.
- Check the retroactive date at every renewal and especially when switching insurers.
- An Extended Reporting Period (ERP), where offered, gives extra time to report claims – it doesn’t cover new work. One wording allows 60 days; another allows 90.
What Does Claims-Made Basis Mean in Professional Indemnity Insurance?
A claims-made policy covers claims first made against the professional during the policy period, for work done after the retroactive date – not simply errors that happened during the policy period. This matters because professional mistakes often surface long after you finished the work.
Under a claims-made policy:
- The policy period is the window in which the claimant must make the claim.
- You must report the claim to the insurer as the policy requires. Universal Sompo’s wording, for example, covers claims “first made against the Insured and notified to the Insurer during the period of insurance”. The ICAI scheme and Royal Sundaram’s medical wording refer to claims “first made in writing” during the period.
- The retroactive date sets how far back the covered work can go.
- Continuity between policy periods keeps earlier work covered.
- Exclusions and conditions still apply, including exclusions for known prior claims (for example, Universal Sompo Excl. 13) and disclosure duties.
“Claims-made” and “claims-made-and-reported” are not the same trigger. Check which one your wording uses.
Key Dates in a Claims-Made Policy
| Term | General Meaning | Why It Matters |
|---|---|---|
| Date of professional act or omission | When the alleged error, omission or other relevant event occurred | Helps decide whether the act falls within the policy’s temporal scope |
| Claim first made | When a claim is first made against the insured, as defined by the policy | May need to fall within the policy period |
| Claim reported | When the claim is notified to the insurer | Must meet the policy’s notification requirements |
| Policy period | The period during which the policy is in force | Defines the coverage window, subject to the wording |
| Retroactive date | The date used to decide whether earlier acts or omissions are eligible | May affect whether earlier work is covered |
| Extended Reporting Period | Where provided, extra time to report qualifying claims after expiry or cancellation | May allow some claims to be reported after expiry, without covering new acts |
What Is a Retroactive Date in PI Insurance?
The retroactive date is the earliest date from which the policy can cover professional work; it generally excludes claims about work done before it. Insurers set it because a claims-made policy could otherwise pick up claims from many years of earlier work. They may refuse to backdate it, or charge more for an earlier date, depending on their view of the past risk.
Also, the retroactive date isn’t necessarily the date you bought the policy or the date of the claim. For a professional with continuous cover, it is often the date their first policy began, if insurers have carried it forward. So always read it alongside the policy period, the claim and reporting rules, and the exclusions.
Hypothetical example. A consultant’s policy has a retroactive date of 1 April 2022. During the current policy period, a client claims over work done in 2023. The 2023 work falls after the retroactive date, so timing isn’t a barrier. However, coverage still depends on correct claim and reporting timing, and on no exclusion applying.
| Situation | General Consideration |
|---|---|
| Relevant work occurred after the retroactive date | Timing may satisfy the retroactive-date requirement, subject to other conditions |
| Relevant work occurred before the retroactive date | The claim may fall outside the policy’s temporal scope |
| Claim first made outside the policy period | Cover may be unavailable unless a provision, such as an ERP or notice of circumstances, applies |
| Claim made during the period but reported late | The outcome depends on the reporting wording and any applicable provisions |
| A circumstance was known before the policy began | Prior-known-circumstance terms and disclosure duties may affect cover |
Why Is the Retroactive Date Important?
Claims about professional work can arrive months or years after the work, so the retroactive date decides whether the policy still protects that earlier work. This matters most for long-tail work, such as legal documents, audits, structural designs and long-running IT projects.
Lapses in cover, changed terms or a new insurer can all move the retroactive date forward, leaving earlier work uncovered. So always check that the insurer has kept the date.
Keeping the same date isn’t enough on its own, though. The new policy’s wording, exclusions, claim requirements, and treatment of prior acts also matter.
What Happens to the Retroactive Date at Renewal?
At renewal, the retroactive date should normally carry forward unchanged – but don’t assume it has. Check the renewal schedule each year. Policies can also change in other ways at renewal, such as exclusions, limits, deductibles, insured services and notification rules. Renewing with the same insurer doesn’t guarantee identical terms.
Some schemes set specific rules. The ICAI scheme’s endorsement, for example, limits the previous retroactive date to “not earlier than 2 years” before the new insurance begins, provided cover is continuous, and says it does not treat a one-day break as a break. Other wording may differ.
Finally, if anything is unclear, ask the insurer or broker in writing.
Renewal checklist
- Confirm the retroactive date on the renewal schedule.
- Compare it with the previous policy.
- Check for any change to the coverage trigger or reporting requirements.
- Review exclusions and prior-known-circumstance provisions.
- Confirm that the insured professional services are still accurate.
- Check limits, deductibles, and sub-limits.
- Confirm the renewal takes effect without a gap.
- Keep copies of previous schedules, wordings, endorsements, and renewal documents.
What Happens to the Retroactive Date When Switching Insurers?
A new insurer may offer a different, later retroactive date – which can leave earlier work uncovered – so confirm the date before switching, not after.
- The new insurer decides, through its underwriting, whether to accept your existing retroactive date. It has no obligation to.
- Keeping the date isn’t the same as covering every prior act. The new wording, exclusions, and definitions decide that.
- You must disclose known claims and circumstances on the new proposal. Policies also commonly exclude prior known claims.
- Avoid any gap between the old policy’s expiry and the new policy’s start.
- Check whether you need an ERP or run-off cover from the old insurer.
| Item to Check | Existing Insurer | New Insurer | Why It Matters |
|---|---|---|---|
| Retroactive date | Record the date in the current policy | Confirm the date accepted in the proposed policy | A later date may restrict cover for earlier work |
| Coverage trigger | Review the claims-made or claims-made-and-reported wording | Review the proposed policy’s wording | Claim and reporting conditions may differ |
| Prior acts | Review the scope of existing cover | Confirm which prior acts, if any, are accepted | A date alone doesn’t establish full prior-acts cover |
| Known circumstances | Check existing notification and disclosure records | Meet the new proposal and disclosure requirements | Known circumstances may affect cover |
| Exclusions | Review current exclusions | Compare proposed exclusions and endorsements | Similar-looking policies may cover different risks |
| Policy continuity | Confirm expiry and renewal dates | Confirm the start date and any transition arrangements | Gaps may create coverage problems |
| Reporting provisions | Review existing notification requirements | Review the new reporting requirements | Reporting obligations may differ |
What Is an Extended Reporting Period (ERP)?
An Extended Reporting Period is extra time after a policy ends during which you can still report qualifying claims, where the policy provides one. Some wordings call it a discovery period, or an extended claim reporting clause.
An ERP can matter when:
- you don’t renew a policy
- a professional retires or closes a practice
- insurance arrangements change
However, the terms vary:
- Universal Sompo’s wording allows 60 days after expiry if you don’t renew the policy, or if it ends by cancellation for a reason other than non-payment. The insurer treats such claims as made in the expired period, and it doesn’t reinstate the limit (Extension 6).
- The ICAI scheme allows up to 90 days after expiry or cancellation, only if no other insurance is in force for the same interest, and only for events during the period of insurance (Cl. 5(b)).
- Royal Sundaram’s medical wording doesn’t define a separate ERP.
Check the availability, length, cost, activation conditions, and eligibility in your own policy. An ERP is not a new policy period, and it doesn’t cover new work.
Four related terms:
- Retroactive date – how far back the covered work can go.
- Policy period – when the policy is in force.
- Extended Reporting Period – where provided, extra time to report qualifying claims after the policy ends.
- Run-off cover – a separate arrangement covering claims about past work after retirement or closure, under its own wording. SecureNow explains run-off cover in more detail.
Extended Reporting Period vs Policy Extension vs Run-Off Cover
| Feature | Extended Reporting Period | Policy Extension | Run-Off Cover |
|---|---|---|---|
| Main purpose | May allow qualifying claims to be reported after the policy ends | May extend the policy period or specified cover, depending on the endorsement | May protect against claims about past work after operations or arrangements change |
| New professional work after expiry | Not automatically covered | Depends on the extension terms | Depends on the run-off arrangement and wording |
| Reporting window | Set by the policy or endorsement (60 or 90 days in the wordings reviewed) | Depends on the amended period and terms | Depends on the run-off policy or endorsement |
| Availability | Only if provided or agreed | Requires a policy provision or agreement | Requires a run-off arrangement |
| Key check | Eligible claims, reporting deadline, activation conditions | Effective dates and exact scope | Retroactive date, covered prior work, exclusions, reporting rules |
Names and mechanics vary between wordings. Rely on the contract, not the label.
Worked Timeline Examples – Retroactive Date and Claims-Made Coverage
These are hypothetical illustrations, not claim decisions or legal advice. They assume a claims-made-and-notified policy with an annual period, unless stated otherwise.
Example 1: Professional Work After the Retroactive Date
| Event | Date |
|---|---|
| Retroactive date | 1 April 2022 |
| Policy period | 1 April 2025 – 31 March 2026 |
| Alleged error | 15 September 2023 |
| Claim first made | 10 December 2025 |
| Claim reported | 12 December 2025 |
The work comes after the retroactive date, and both the claim and the report fall within the policy period. Timing issue: none apparent. Conclusion: the timing works, but cover still depends on the wording, exclusions, and other conditions.
Example 2: Professional Work Before the Retroactive Date
| Event | Date |
|---|---|
| Retroactive date | 1 April 2024 |
| Policy period | 1 April 2025 – 31 March 2026 |
| Alleged error | 10 January 2024 |
| Claim first made | 20 August 2025 |
| Claim reported | 22 August 2025 |
The claim and the report both arrive in time, but the work predates the retroactive date. Timing issue: the wording reviewed excludes acts before the retroactive date. Conclusion: likely outside the temporal scope, but check the wording and any prior-acts terms before deciding.
Example 3: Claim Reported After Policy Expiry
| Event | Date |
|---|---|
| Retroactive date | 1 April 2022 |
| Policy period | 1 April 2025 – 31 March 2026 |
| Alleged error | 1 November 2024 |
| Claim first made | 25 March 2026 |
| Claim reported | 5 April 2026 |
The claim arrived before expiry, but the professional reported it five days later. Timing issue: under a claims-made-and-notified wording, late reporting is a problem, unless the professional renewed the policy or an ERP applies. A 60- or 90-day ERP, like those in the wordings reviewed, could cover this report if the professional meets its conditions. Conclusion: this case needs further review. Check for renewal, the ERP terms, and the reporting wording.
Example 4: Switching Insurers With Different Retroactive Dates
| Event | Date |
|---|---|
| Old policy retroactive date | 1 April 2021 |
| Old policy expires | 31 March 2026 |
| New policy begins | 1 April 2026 |
| New policy retroactive date | 1 April 2024 |
| Alleged error | 10 June 2022 |
| Claim first made | 15 July 2026 |
The claim falls under the new policy, but the work predates its retroactive date. The old policy has expired, and the claim falls outside a 60- or 90-day ERP window. Timing issue: potential gap. Conclusion: check whether the new insurer accepted prior acts, whether the old policy had a notice-of-circumstances provision that the professional used, and whether they bought run-off cover. Don’t assume the old policy will respond.
Key Lesson From These Examples
Coverage depends on four dates working together – the work, the claim, the report and the retroactive date – plus the policy wording. Getting one date right isn’t enough.
Common Mistakes to Avoid
- Assuming the retroactive date carries forward automatically – check every renewal schedule.
- Switching insurers without confirming the new date – a later date can leave earlier work uncovered.
- Confusing the date of the error with the date of the claim – claims-made cover turns on the claim date.
- Ignoring reporting requirements – some wordings require notification within the period.
- Assuming an ERP covers new work – it only extends the time to report.
- Not disclosing known circumstances – policies commonly exclude prior known claims.
- Letting a gap open between policies.
- Relying on the certificate alone – read the schedule and the wording.
How to Maintain Continuity in PI Insurance
- First, keep an organised record of past schedules and wordings.
- Check the retroactive date at every renewal.
- Compare retroactive dates when switching insurers.
- Confirm how any new policy treats prior work.
- Disclose claims and circumstances as required. Use any notice-of-circumstances clause to notify potential claims during the period.
- Also, follow the claim notification requirements.
- Review ERP or run-off options before a policy ends, where relevant.
- Ask the insurer or broker to clarify in writing.
- Finally, take professional advice where the stakes are high.
These steps reduce avoidable gaps; they don’t guarantee cover. To learn how insurers handle claims, read SecureNow’s guide to the professional indemnity claims process.
Conclusion
Under claims-made PI cover, the date of the work alone doesn’t decide coverage. The claim and reporting requirements, the retroactive date and the continuity of cover all matter, especially at renewal and when changing insurers. An ERP can help with reporting qualifying claims after expiry, but it doesn’t cover new work. In every case, the actual wording, schedule, exclusions and endorsements decide the outcome.

Frequently Asked Questions
Q) What does claims-made basis mean in PI Insurance?
A) It means the policy covers claims first made against the professional during the policy period – and, under some wordings, also reported during it – for work done after the retroactive date. When you did the work matters less than when the claim arrives, subject to the wording and exclusions.
Q) What is a retroactive date in Professional Indemnity Insurance?
A) It is the earliest date from which a claims-made policy can cover professional work. The policy generally excludes claims about work you did before it. The schedule sets it, and it isn’t necessarily the date you bought the policy.
Q) Why is the retroactive date important at renewal?
A) Because it decides whether earlier work stays covered. If the date moves forward at renewal, or cover lapses, claims about earlier work may fall outside the policy. Check the renewal schedule against the previous policy every year.
Q) What happens to the retroactive date when switching insurers?
A) The new insurer decides, through underwriting, whether to accept your existing retroactive date; it has no obligation to. A later date may leave earlier work uncovered, so get the insurer to confirm the date and the prior-acts terms in writing before switching.
Q) What is an Extended Reporting Period in PI Insurance?
A) It is extra time after a policy ends to report qualifying claims, where the policy provides one. One published wording allows 60 days after non-renewal; an association scheme allows up to 90 days, if no other insurance is in force. Terms vary, and some policies have none.
Q) Does an Extended Reporting Period cover new professional work?
A) No. An ERP only extends the time for reporting claims about work within the original policy’s scope. It doesn’t create a new policy period or cover work done after the policy ended. For that, you need run-off cover or a new policy.
Q) Can a policy cover a claim if the professional error happened before the policy started?
A) Possibly, if the error happened after the policy’s retroactive date and both the claim and its report fall within the policy period. However, policies generally exclude work done before the retroactive date, and they usually exclude known prior claims too.
Q) What happens if you report a claim after the policy expires?
A) It depends on the wording. If you renewed the policy, the claim may fall under the new period. If not, an ERP – where available – may allow late reporting within its window. Under a claims-made-and-notified wording, without either of these, the policy may not cover the claim.
Q) Is a retroactive date the same as the policy start date?
A) Not necessarily. The policy start date begins the current period. The retroactive date may be much earlier if you have maintained continuous cover and insurers have carried it forward. For a first-time policy, the two may be the same.
Q) How can professionals avoid gaps in PI insurance coverage?
A) Renew without breaks, check the retroactive date every year, confirm it in writing when switching insurers, disclose known circumstances, notify potential claims during the policy period, and arrange an ERP or run-off cover before retiring or closing a practice.
