Initial investigation is the first round of fact-finding undertaken by the insurer (often through a loss adjuster, panel solicitor or in-house handler) to determine, on a preliminary basis, what happened, whether the policy responds and what the likely quantum is.
Initial investigation is the bridge between acknowledgement and substantive handling. Its purpose is to put the insurer in a position to take coverage and reserving decisions on an informed basis — not to determine those questions definitively, but to map the terrain. A good initial investigation captures the relevant facts, identifies the policies in force, isolates the key coverage issues, sketches a quantum range, and surfaces any conduct or fraud red flags that would justify a reservation of rights, a coverage opinion or a referral to a special investigations unit.
The investigation may be conducted by a single party (the in-house handler) or by a small team (handler, loss adjuster, panel solicitor, sometimes counsel and forensic experts). The depth varies with the complexity and value of the claim. A motor own-damage claim of £4,000 needs an engineer’s report and a body-shop quote. A £40 million construction-defects claim needs a multi-disciplinary team running in parallel for months.
The duty to investigate properly is implicit in ICOBS 8.1.1R (handle claims promptly and fairly) and ICOBS 8.1.2G (provide reasonable guidance and not unreasonably reject claims). It is also implicit in Insurance Act 2015 section 13A: an insurer that has not investigated cannot have formed a reasonable view on whether sums are due, and so cannot rely on the “reasonable time” defence indefinitely. The longer the investigation, the heavier the burden on the insurer to show it was acting reasonably.
For consumer business, the FCA’s Treating Customers Fairly framework (now subsumed under the Consumer Duty in PRIN 2A) requires that investigations be proportionate to the claim value. A consumer is entitled to expect that an insurer will not run up disproportionate investigation costs on a small claim, and will not delay payment of a clear claim by demanding marginally relevant evidence.
For claims that may involve criminal conduct, professional misconduct or regulatory breach by the insured, initial investigation must also consider whether to notify regulators or law-enforcement agencies. Solicitors firms, for example, must report material breaches to the SRA; a property fire investigation that uncovers arson must be reported to the police; a financial-services firm with a claim implying mis-selling must consider FCA notification.
The skeleton of an initial investigation runs through six steps.
First, gather the policy. The handler pulls every policy in force on the date of loss, plus any earlier policies that may respond on a claims-made basis. For professional indemnity in particular, the policy schedule, schedule of insurers, full wording, endorsements, retroactive date and any premium adjustments are all needed.
Second, gather the underlying facts. For a property loss this means site attendance by an adjuster within 24-72 hours, photographs, witness statements, surveyor’s reports and any fire- or police-service reports. For a casualty loss it means medical records, accident reports, CCTV and engineer’s reports. For a professional negligence claim it means the underlying client file, the letter of claim, the firm’s response and a chronology.
Third, take a preliminary view on coverage. Are all the policy conditions satisfied? Are there obvious exclusions? Does the wording aggregate the claim with prior matters? Is there a retroactive-date issue? Where the answers are not clear, a coverage opinion is commissioned (in-house counsel, panel solicitor or, for the most complex matters, leading insurance counsel).
Fourth, take a preliminary view on quantum. The handler develops a range — best, central and worst case — using comparable settlements, panel adjuster guidance, counsel’s view on damages, and any expert input.
Fifth, set or revise the case reserve. The initial reserve set at acknowledgement is updated to reflect what the investigation has revealed.
Sixth, plan next steps. The handler closes the initial-investigation phase by setting a defence strategy (if proceedings are likely), a settlement plan (if early settlement is preferable), or a watch-and-wait posture (if the claim is dormant).
Initial investigations differ sharply between lines of business. In motor personal injury the bulk is done by a claims technician using digital tools and external panel reports, typically completed within two or three weeks. In professional indemnity the work is led by the panel solicitor, with the handler in a strategic and approval role, and typically takes six to twelve weeks. In major property and business interruption the work is led by a chartered loss adjuster reporting weekly, and may take six months. In Lloyd’s binders, the TPA conducts the investigation under the binder’s claims authority, with the carrier reviewing in batches.
Investigations may also be re-opened. A “supplementary investigation” is triggered by new information — a witness coming forward, a previously concealed document being discovered, fraud red flags emerging in late documents. The supplementary investigation is governed by the same standards as the initial.
A national accountancy firm notifies a £5m professional indemnity claim relating to alleged negligent audit advice on a 2022 fundraise. The initial investigation is conducted over six weeks: the panel solicitor reviews the audit working papers, the engagement letter and the firm’s risk-management documentation; counsel produces a coverage opinion confirming that the policy responds (subject to a contested aggregation issue with two related advisory engagements); a forensic accountant produces a preliminary quantum range of £1.4 million to £4.8 million depending on causation; and the handler revises the case reserve from £1.5 million (initial) to £3.2 million (post-investigation, with £600,000 of defence costs). The file then moves to substantive defence, with a joint settlement meeting tentatively scheduled for nine months later.
