Notification vs claim in UK PI insurance — the practical distinction that protects the cover

Every PI wording distinguishes between two events: a notification of circumstance (something that might give rise to a claim) and a claim (a demand or process actually made against the firm). The difference matters more than most firms realise — failing to notify a circumstance can void cover on any resulting claim.

The two concepts

1. Notification of circumstance. The firm tells the insurer about an event or set of facts that could reasonably be expected to give rise to a claim. No formal claim has been made yet.
2. Claim. A demand for compensation, service or work, or the commencement of legal proceedings, made against the firm.

Why the distinction matters

PI insurance is claims-made. A claim is only covered by the policy in force when the claim is first made. But notification of circumstance triggers a ‘deeming’ provision in most wordings — the eventual claim, whenever it arises, is deemed to be made under the policy that received the original notification.

This means: a notification given now protects the firm even if the claim itself doesn't crystallise for years. It captures the eventual claim under the current policy, regardless of what the firm's cover looks like when the claim actually arrives.

What triggers a notification duty

The wording matters — different policies use different language — but the substance is typically: any facts, circumstances or matters that the firm knows or should have known could give rise to a claim.

1. Complaint from a client, whether formal or informal, that touches on the firm's work.
2. Discovery of a mistake in a deliverable already provided to a client.
3. Client asking for compensation, refund or re-performance without formally claiming.
4. Regulatory investigation or inquiry that relates to specific client work.
5. Third-party claim or process where the firm's work is implicated.
6. Facts learned by the firm that suggest a past deliverable may have caused loss.

What insurers do when they receive a notification

1. Log the notification against the current policy.
2. Investigate or reserve, depending on the nature.
3. Instruct panel solicitors if potential liability is material.
4. Confirm cover position in writing.
5. Handle any follow-on claim under the policy that received the notification.

Claims-made cover against occurrence cover

The distinction between a notification and a claim exists because PI cover is triggered by the claim, not by the work.

Common firm mistakes

1. Late notification. Firm knew about the circumstance for months before telling the insurer. Wordings typically require notification ‘as soon as practicable’ or ‘during the policy period’.
2. Under-notification. Firm decides the matter is unlikely to become a claim and doesn't notify. If it later does become a claim under a different policy, cover may be disputed.
3. Overly detailed notification. Firm provides an implicit admission of liability in the notification. Discuss framing with the broker before sending.
4. Notification only after receiving a claim. If a circumstance was known during a prior policy and not notified then, the current policy may not respond.
5. Notification without full facts. Firm notifies bare details without follow-up when facts develop. Insurer needs the whole picture.

When to notify

1. Immediately on receipt of a complaint or claim-like communication.
2. Within days of discovering a material mistake in a completed deliverable.
3. As soon as a client reasonably suggests a claim may follow.
4. Well before policy renewal if a matter emerged during the outgoing policy year.
5. Any time the firm's risk-management review identifies a potential exposure.

The broker's role in notification

1. First point of contact — discuss the facts, help frame the notification.
2. Presentation to insurer — consistent format, proper detail, appropriate hedging.
3. Ongoing management — response to insurer follow-up, panel-solicitor engagement.
4. Position defence — where the firm has a good defence to the eventual claim, present it early.
5. Coverage protection — where the wording is ambiguous, argue the firm's position with the insurer.
