First notification of loss is the moment an insured (or its broker) first tells its insurer that an event has occurred which may give rise to a claim — and the trigger that starts the entire claims-handling clock.
First notification of loss, almost universally abbreviated to FNOL, is the formal communication by an insured or its representative to the insurer that an incident has happened — a fire, an accident, a customer complaint, a cyber intrusion, a writ — that the insured believes is, or may become, the subject of an insurance claim. In personal lines it is most often a telephone call to a 24-hour notification centre. In commercial and Lloyd’s-market business it is more often a written notice from the broker to the leading underwriter, supported by a claim form, statement of facts or letter of claim.
FNOL is not the claim itself. It is the procedural event that opens a claim file, triggers acknowledgement obligations under the FCA’s Insurance Conduct of Business Sourcebook, fixes the date by reference to which the “reasonable time” under section 13A of the Insurance Act 2015 begins to run, and, in claims-made policies, is the act that brings the matter within cover. Insurers treat the FNOL touchpoint as the most important moment in the customer journey: industry studies consistently show that customer-satisfaction outcomes and ultimate claim cost are both driven more by what happens in the first 24 to 72 hours than by anything that follows.
The duty to notify is contractual: every UK policy contains a claims condition requiring the insured to notify the insurer of any claim, circumstance or event within a defined period, often “as soon as reasonably practicable” or “within thirty days”. Whether breach of that condition has consequences depends on whether it is drafted as an ordinary term, an innominate term, a condition precedent to liability, or a forfeiture clause.
For consumer policies the regulatory frame is ICOBS 8 (Claims handling) in the FCA Handbook, which requires insurers to handle claims promptly and fairly, give reasonable guidance and not unreasonably reject a claim — including not rejecting a claim for breach of a duty (such as notification) that did not cause the loss. Section 11 of the Insurance Act 2015 limits insurers’ ability to refuse a claim for breach of a term aimed at reducing a particular risk where the breach could not have increased the risk of the loss that occurred.
For business policies, Insurance Act 2015 section 13A imposes an implied term that insurers will pay sums due within a reasonable time, with damages available for breach. The reasonable-time clock starts running on FNOL (or, more precisely, on the insurer’s receipt of the information needed to investigate). FOS Rules in DISP 2 give the Financial Ombudsman Service jurisdiction over claims-handling complaints from eligible complainants. For Lloyd’s syndicates and authorised insurers, PRA SS18/16 (and successor materials) set expectations on claims-management operational resilience.
A typical FNOL flow for commercial business runs through four stages. First, intake: the broker takes a call from the insured, captures core facts (policy number, date of loss, location, brief description, contact for further information) and notifies the insurer the same working day. The broker’s email confirms the notification, attaches any documents (photographs, letter of claim, police reference, regulator letter) and asks for an acknowledgement. Second, acknowledgement: the insurer’s claims unit logs the file, allocates a handler and sends an acknowledgement quoting a claim reference, a request for any missing information and the handler’s contact details. ICOBS expects this to happen within working days, not weeks.
Third, initial scoping: the handler makes a preliminary coverage assessment — does the policy in force respond, is there an obvious exclusion in play, does the claim look like one that the leading insurer can settle alone or does it need a coverage opinion or counsel’s view. Fourth, reserve setting: a case reserve is posted (with an additional IBNER element if the early facts justify it) and the file moves to substantive handling.
For personal lines, the process is compressed and automated. A motor FNOL captured by an interactive voice response or web form may, within minutes, deploy a recovery vehicle, dispatch an engineer to a body shop, instruct a credit-hire firm, allocate liability provisionally, and post an initial case reserve. Insurtechs have shortened the median FNOL-to-first-payment cycle for simple property claims from days to hours by combining mobile photo capture, machine-learning damage assessment and same-day bank transfer.
For Lloyd’s market business notification typically flows through the broker into the ECF (Electronic Claim Files) system at Xchanging, where the slip leader receives, evaluates and responds. Single Claims Agreement Party (SCAP) protocols allow the leader to bind the following market for small claims.
Notification of a “claim” should be distinguished from notification of a “circumstance”. In claims-made wordings (professional indemnity, D&O, cyber) the policy responds to claims first made during the policy period — but the same wording also typically allows the insured to notify circumstances that may give rise to a claim, fixing the matter within the year of notification regardless of when the claim itself crystallises. The classic claims-made-and-reported wording requires both events to fall within the period.
FNOL is also distinguished from “claim made”. A claim is “made” against the insured when a third party makes a demand or commences proceedings; FNOL is when the insured tells its insurer. Coverage often turns on the date of the former, but the conduct clock runs from the latter.
Internally, insurers distinguish between FNOL, “first advice of loss” (where a broker flags a possible loss without complete information) and “watch notice” (where the broker asks the insurer to monitor a potential exposure). All three open files; only FNOL formally starts the substantive claim.
A solicitor’s firm with a £3m primary professional indemnity policy receives a letter of claim on 5 May alleging negligence in a 2022 conveyance. The firm’s COLP forwards the letter to the broker the same afternoon. The broker emails the leading underwriter at 17:12 attaching the letter, the policy schedule, the original retainer, the file index, and a brief chronology, asking for acknowledgement and the handler’s details. The insurer logs the FNOL on 6 May, allocates a senior handler, instructs a panel solicitor for a coverage and merits view within ten working days, and posts an initial case reserve of £450,000 (indemnity £350,000, defence costs £100,000). The “reasonable time” clock under section 13A starts on 6 May; the panel solicitor’s coverage opinion three weeks later confirms cover and triggers the substantive defence strategy.
