The consequences of notifying a professional indemnity claim late
Reviewed by Matthew Bartlett, Director, Apex Insurance Brokers Limited · Last reviewed 2026-08-05
Why "claims-made" makes timing critical
Most professional indemnity (PI) policies in the UK are claims-made, not "losses occurring". A losses-occurring policy (like most public liability cover) responds to events that happen during the policy year, whenever the claim eventually surfaces. A claims-made policy is different: it responds to claims first made against you and notified to the insurer within the period of insurance.
That single design feature is why timing dominates PI. The trigger is not when you made the alleged mistake, or when the client suffered a loss. The trigger is when the claim is made and reported. If a demand lands on your desk in one policy year and you sit on it until the next, you may be trying to claim under a policy that no longer covers it — and the current policy may treat it as a pre-existing matter it never agreed to insure.
Notification as a condition precedent
PI wordings almost always require you to notify a claim, or a circumstance that might give rise to one, "as soon as reasonably practicable" or "immediately" once you become aware of it. Many wordings make this a condition precedent to the insurer's liability. The practical effect is stark: if you breach that condition, the insurer can be entitled to decline the claim, regardless of whether the underlying allegation against you has any merit.
This is a harsher position than many people expect. Under the Insurance Act 2015, insurers lost the ability to avoid a whole policy for a minor, innocent breach of the duty of fair presentation. But the Act did not sweep away condition-precedent notification clauses. A clearly worded notification condition can still be enforced, and a genuinely late notification can still cost you the claim.
Not sure your PI cover is set up to protect you on notification? We will review the wording and place cover that fits how you actually work.

- The claim falls into a gap. If a claim is made this year but notified after renewal, the expired policy no longer accepts new notifications and the renewed policy excludes matters you already knew about. The claim lands in neither.
- You lose the deeming protection. When you notify a circumstance during the policy period, most wordings "deem" any later claim arising from it to have been made during that period — even years later. Miss the window and you forfeit that protection.
- Prejudice arguments strengthen. Delay lets evidence go stale, files get lost and limitation periods shorten. Even where an insurer cannot decline outright, delay that has prejudiced the defence can reduce what they pay.
- Prior-knowledge exclusions engage. A new insurer will exclude any matter you were aware of before inception. Sit on a circumstance across a renewal and you may have created an uninsured problem.
- Your renewal presentation is compromised. Under the Insurance Act 2015 you must make a fair presentation of the risk. Failing to disclose a known circumstance at renewal is a separate breach that can affect the whole policy, not just one claim.
Claims-made versus losses-occurring at a glance
| Claims-made (PI) | Losses-occurring (e.g. PL) | |
|---|---|---|
| What triggers cover | Claim first made and notified in the period | The event/injury occurs in the period |
| When you must notify | Promptly, within the current period | Promptly, but the old policy still responds |
| Effect of a gap in cover | Serious — claim may fall outside all policies | Historic events usually remain covered |
| Late-notification risk | High — can void the individual claim | Lower on timing, still a duty to report |
The takeaway: in a claims-made world, the calendar is part of your cover. Treat notification as an urgent task, not admin to get to later.
Notify circumstances, not just claims
The most valuable habit in PI is notifying circumstances early. A circumstance is any incident, complaint, error or set of facts that might reasonably be expected to give rise to a claim — a client hinting at dissatisfaction, a missed deadline, a report you suspect contained a mistake. You do not need a formal demand or a letter from a solicitor.
Notifying a circumstance during the current policy period locks it into that policy. If a claim later crystallises — even after the policy has expired — it is treated as having been made when you first flagged the circumstance. That protects you across renewals and against future prior-knowledge exclusions. Under-notifying to keep a clean record is a false economy; a well-documented circumstance notification is one of the strongest protections your PI policy offers.
If you are unsure whether something qualifies, tell your broker and let the insurer decide. A precautionary notification rarely does harm; silence can be fatal to cover. Talk to us about your notification process if you are not confident it is watertight.
Practical steps to protect yourself
- Read the notification clause in your own wording — know the exact trigger words and whether it is a condition precedent.
- Route every complaint, error or hint of a dispute to one named person internally, so nothing is quietly parked.
- Notify your broker or insurer in writing and keep the acknowledgement.
- Do not admit liability, settle or offer to "make it right" before notifying — that can itself breach the policy.
- Sweep for open circumstances before every renewal and report them before the old policy lapses.
Common questions
Can an insurer really refuse a genuine claim just because I told them late?
Potentially, yes. Where notification is a condition precedent to liability, a late report can entitle the insurer to decline the claim on its own, separate from the merits of the allegation against you. That is why prompt notification matters as much as being right.
What is the difference between notifying a claim and notifying a circumstance?
A claim is an actual demand or allegation against you. A circumstance is an early warning — facts that might lead to a claim. Notifying a circumstance during the policy period secures cover for any claim that later grows out of it, even after the policy ends.
I have found an old error but nobody has complained yet. Should I notify?
Usually, yes — as a circumstance. Reporting it now anchors any future claim to your current policy and avoids it being caught by a prior-knowledge exclusion at your next renewal. Speak to your broker before deciding not to.
