What is a circumstance notification in PI insurance?

Why circumstance notifications exist

Professional indemnity (PI) insurance in the UK is almost always written on a claims-made basis. That means the policy responds to claims first made against you (and notified to insurers) during the policy period — not to the date you did the work or made the alleged mistake. The trigger is the claim, not the act.

This creates an obvious problem. What happens when you become aware that something has gone wrong — a drawing was miscalculated, advice may have been negligent, a client is unhappy — but no formal claim, letter of claim or demand for compensation has yet arrived? A claim might come next month, next year, or after your policy has renewed with a different insurer. The circumstance notification is the mechanism that closes that gap.

By reporting the circumstance to your current insurer, you effectively lock the matter into the policy that is in force when you first became aware of it. Most PI wordings contain a “deeming” provision: any claim that later arises out of a circumstance you validly notified is treated as if it were made during the policy period in which you notified it. The insurer on risk today stays responsible for it, regardless of who insures you when the claim finally materialises.

Circumstance vs claim: what is the difference?

The two are related but distinct, and PI policies treat them differently.

A claim is a demand made against you for compensation or damages — for example, a client’s solicitor writing to allege loss caused by your work, or formal proceedings being issued. There is a defined assertion of liability against you.

A circumstance is earlier and softer. It is any fact, event or awareness that could reasonably be expected to give rise to a claim, even though no demand has yet been made. Wordings phrase this in different ways — “circumstances which may give rise to a claim” is common — but the common thread is anticipation rather than an actual dispute.

Examples of a circumstance might include a client complaining that your advice cost them money, discovering an error in a survey or set of accounts you produced, a project going badly wrong on site, or an angry email hinting at legal action. None of these is a claim yet. All of them may become one.

Why prompt notification matters

Timing is the single most important thing to get right. There are two reasons, and both can decide whether you are covered at all.

1. The circumstance must be notified during the policy period. A claims-made policy only protects you for circumstances you notify while it is live. If you sit on a known problem, let the policy renew, and only report it later, the original insurer is off risk — and your new insurer will usually exclude anything you were already aware of when the new policy incepted. The matter can fall between two policies and be covered by neither. Notifying promptly, before renewal, keeps the matter anchored to the insurer who was on risk when you first knew.

2. Policy conditions require it. PI wordings typically require you to notify circumstances “as soon as reasonably practicable” or “as soon as possible” after becoming aware of them. Where notification is drafted as a condition precedent to the insurer’s liability, a late or missed notification can give the insurer grounds to decline the claim. Prompt notification also lets insurers and their appointed defence lawyers get involved early, when a matter is still manageable and before a small complaint escalates into expensive litigation.

How to make a valid circumstance notification

A good notification is specific. Vague, catch-all or “blanket” notifications — for example, trying to notify an entire category of work “just in case” at the end of a policy year — may be challenged by insurers as invalid. To be effective, a circumstance notification should generally include:

• The specific facts and events you have become aware of.
• Who is involved — the client, project or matter concerned.
• Why those facts may give rise to a claim against you.
• An indication of the potential nature and scale of any loss, so far as known.
• The date you became aware, and any relevant correspondence.

Route it through your broker and keep a dated record. In practice you notify your broker, who notifies the insurer; the clearer and more particular the information, the more robust the notification.

The disclosure duty at renewal

Circumstance notification connects closely to your duty when you buy or renew cover. Under the Insurance Act 2015, a business buying insurance owes a duty of fair presentation of the risk — broadly, to disclose every material circumstance it knows or ought to know, or to give the insurer enough to put it on notice to ask questions.

A known but unreported circumstance is exactly the kind of thing that engages this duty. If you are aware of a potential claim and fail to disclose it at renewal, the insurer may have remedies for a breach of the duty of fair presentation, and the new policy will typically exclude prior known circumstances in any event. Notifying the current insurer promptly, and disclosing the position clearly at renewal, keeps you on the right side of both the policy and the Act.

A note on limits and cover

Because a notified circumstance is deemed to attach to the policy in force when you notified it, the limit of indemnity and excess of that policy generally apply to any claim that later arises — not the terms of whatever policy is in force when the claim eventually lands. That is one more reason to make sure your limit is adequate before you notify, and to think carefully about the level of cover you carry. UK professionals commonly buy limits such as £1m, £2m or £5m depending on their sector, contracts and client requirements; the right figure depends on your exposure, not a standard number.

Common questions

If I notify a circumstance, does it count as a claim on my record?

A notification is not the same as a paid claim, but insurers do take notifications into account when assessing your risk and pricing at renewal. That is not a reason to withhold one — failing to notify a known circumstance is far more damaging, because it can leave you without cover when a claim finally arrives. When in doubt, notify.

What happens if a claim arrives after I’ve switched insurers?

If you validly notified the underlying circumstance to your previous insurer while that policy was live, the claim is generally handled under that earlier policy through the deeming provision — not your current one. If you never notified it and only became aware after switching, the position is more complicated and depends on the wording; this is exactly why prompt notification before renewal matters so much.

Can I notify a circumstance just to be safe, even if I’m not sure it will become a claim?

Yes — provided there are genuine facts that may give rise to a claim. Precautionary notification of a real, specific circumstance is sensible and protects your position. What insurers resist are vague, blanket notifications with no identifiable facts behind them, which may not be valid. Describe the actual situation and let the insurer assess it.
