Claim notification is the formal process by which a policyholder advises their insurer of a loss, claim, or circumstance that may give rise to a claim, in accordance with the terms of the policy.

Claim notification is the contractual and procedural step by which the insured triggers the insurer’s claim-handling process. It is the formal communication — usually in writing — that brings a loss event, third-party claim or notifiable circumstance to the insurer’s attention.
The legal significance of notification is two-fold. First, it crystallises the insurer’s obligations: until notified, the insurer has no knowledge of the claim and no obligation to investigate, reserve or settle. Second, in many policies, notification is itself a condition of cover. Failure to notify within the policy’s stipulated timeframe or in the prescribed form may relieve the insurer of liability, partially or wholly, depending on whether the notification clause is a condition precedent, an innominate term, or a mere warranty in the colloquial (not statutory) sense.
For claims-made policies — including most professional indemnity, directors’ and officers’, and cyber policies — notification has an even more fundamental role. These policies respond only to claims first made against the insured and notified to the insurer during the period of insurance (or any extended reporting period). Notification is not merely procedural; it is the very mechanism by which cover attaches.
Notification clauses commonly require the insured to give notice “as soon as practicable”, “as soon as reasonably possible”, or “within [X] days” of the insured becoming aware of the loss or claim. The precise language matters: courts have construed these phrases differently, with the strictness of construction depending on whether the clause is expressed as a condition precedent and on the commercial context.
In consumer insurance, notification requirements are tempered by the FCA’s conduct rules, which prevent insurers from rejecting claims on the grounds of late notification unless the delay has prejudiced the insurer.
The framework governing claim notification draws on contract law, statute and regulation. At common law, a notification clause is interpreted according to its terms, with the court considering whether the parties intended strict compliance to be a condition precedent. The leading authority is HSBC Bank plc v Liberty Mutual Insurance Co (UK) Ltd [2002] Lloyd’s Rep IR 224, in which the Court of Appeal considered the meaning of “circumstance” in a professional indemnity notification clause and held that a sufficiently identifiable matter must be notified.
The Insurance Act 2015 introduced significant reforms. Section 11 deals with terms not relevant to the actual loss: an insurer cannot rely on breach of a term to refuse a claim if compliance would not have reduced the risk of the loss that actually occurred. While section 11 is principally directed at risk-control warranties, it has been argued to apply to notification clauses in some circumstances, though this remains contested.
Section 13A of the Insurance Act 2015 (inserted by the Enterprise Act 2016) imposes an implied term that the insurer pay claims within a reasonable time. The reasonable-time clock begins to run from notification.
For consumer policies, ICOBS 8.1.1R provides that an insurer must handle claims promptly and fairly, and ICOBS 8.1.2G makes clear that insurers should not refuse claims on technical or unreasonable grounds. The Financial Ombudsman Service routinely upholds complaints where insurers seek to rely on late notification absent demonstrable prejudice.
The Third Parties (Rights against Insurers) Act 2010 also has notification implications: where an insured has become insolvent, statutory transferees stand in the insured’s shoes and may notify directly.
A typical commercial claim notification will set out: (i) the policyholder’s name and policy number; (ii) the date of the loss event or the date the claim was first made or first known; (iii) a description of the incident or claim; (iv) an estimate of quantum, where known; (v) the identities of any third parties involved; and (vi) any immediate steps already taken, such as engagement of solicitors or contractors.
Notification is usually given via the broker, who acts as agent for the insured. The broker will typically use the insurer’s standard claim form, online portal, or dedicated claims email address. For Lloyd’s risks, notification flows through the broker into the Electronic Claims File system and is allocated to the lead and following underwriters.
For binding-authority and delegated-authority business, notification may be made directly to the appointed managing general agent or coverholder, who handles claims under delegated claims-handling authority.
The timing of notification varies sharply by class. Motor insurance typically requires notification within 24–48 hours and as soon as possible if injury is involved (in part to permit the insurer to defend). Professional indemnity insurance usually requires notification “as soon as practicable” after the insured becomes aware. Property policies often have a 7- or 14-day notification window.
Even where no formal time bar applies, prompt notification is critical for several reasons. The insurer’s ability to investigate, take statements, preserve evidence, and engage with third parties depends on early notice. Delay can prejudice the defence of liability claims and can permit further accrual of losses (for example, deterioration of damaged property). Some policies contain “mitigation” or “duty to take reasonable steps” clauses, breach of which by delay may itself give rise to defences.
Insurers, on receipt of notification, will open a claim file, assign a reference, acknowledge receipt, request further information, and, in larger losses, instruct a loss adjuster or coverage counsel. The notification will also trigger establishment of a loss reserve.
Notification can take several forms. Notification of a claim is the simplest case: a specific demand has been received from a third party, or a first-party loss has crystallised. Notification of a circumstance is more nuanced: under claims-made policies, the insured notifies a fact or matter that may give rise to a future claim, thereby locking in cover under the current policy even if the claim itself is not made until a later period.
Precautionary notification is the practice of notifying matters that might never crystallise into claims, simply to preserve cover. Brokers commonly advise this at policy renewal: any matter known to the insured but not yet developed into a claim should be notified to the expiring insurer before the policy lapses.
Block notification or blanket notification is the attempt to notify a broad swathe of potential matters in a single notice. Courts have generally been hostile to such attempts unless the notification is sufficiently specific. In Kidsons v Lloyd’s Underwriters [2008] EWCA Civ 1206 the Court of Appeal considered the validity of a general “hose pipe” notification covering all matters of which the insured was aware.
Late notification is notification given after the time limit specified in the policy. Whether it is effective depends on whether the clause is a condition precedent and on the application of relevant statutory and regulatory protections.
A solicitors’ firm, Hartley & Co, holds professional indemnity insurance with a policy year running 1 October 2025 to 30 September 2026. On 14 August 2026, the firm receives a letter from a former client alleging negligent advice on a 2023 conveyancing transaction. The letter does not yet contain a quantified demand but indicates that proceedings are being considered.
The firm’s compliance partner reviews the policy notification clause, which requires notification “as soon as practicable” of any circumstance that may give rise to a claim, and treats compliance as a condition precedent. The partner instructs the firm’s broker to notify the matter the same week. The broker submits a notification to the insurer on 19 August 2026, attaching the letter, the relevant conveyancing file summary, and the firm’s initial coverage analysis.
The insurer acknowledges the notification on 20 August 2026, assigns a claim handler, instructs coverage counsel and a panel solicitor, and sets an initial loss reserve of £150,000. Because the notification was made within the 2025/26 policy year and within a reasonable time after the firm became aware, cover attaches under the 2025/26 policy even if proceedings are not issued until 2027 or later. Had the firm failed to notify until renewal, cover under the 2025/26 policy would have lapsed and the 2026/27 policy would likely have excluded the matter as a known circumstance.
