A casualty loss adjuster is a loss adjuster specialising in the investigation and quantification of claims under liability insurance policies. The term “casualty” derives from the US insurance market where it broadly denotes liability business, and has become established in the UK to describe adjusters working on third-party injury, damage and economic loss claims, as distinct from first-party property losses.
Casualty adjusters work across the principal classes of UK liability insurance: employers’ liability (EL), public liability (PL), products liability, professional indemnity (PI), directors’ and officers’ (D&O), management liability, environmental liability and motor third-party. They also handle claims under hybrid wordings such as combined liability policies for tradespeople and contractors, and under specialist regimes such as the Compulsory Motor Insurers’ Bureau (MIB) untraced and uninsured driver agreements.
The role is investigative and forensic in character. A casualty adjuster’s task is to establish what happened, who was at fault, what the law and the policy say about liability and indemnity, and what the claim is reasonably worth. The work is generally less site-based than property adjusting, although site attendance is often essential on accident investigations and on professional negligence claims involving construction or engineering. The casualty adjuster’s report typically forms the basis of the insurer’s reserve, the strategy for defence or settlement, and any subsequent litigation.
Casualty adjusters work closely with defence solicitors, medical experts, forensic engineers and accountants. Many adjusters in this specialism also hold legal qualifications such as the Graduate Diploma in Law (GDL) or the Legal Practice Course (LPC), and a significant number have moved between adjusting and the legal profession over their careers.
Casualty adjusting is informed by a wide body of statute, regulation and case law. For employers’ liability claims, the Employers’ Liability (Compulsory Insurance) Act 1969 and the Employers’ Liability (Compulsory Insurance) Regulations 1998 mandate cover for most UK employers and set minimum limits of £5 million. The Employers’ Liability Tracing Office (ELTO) regime supports the tracing of historic policies for claims arising from latent injuries such as mesothelioma. Casualty adjusters handling these claims regularly engage with the Industrial Injuries Disablement Benefit regime and the Compensation Recovery Unit (CRU).
For public and products liability, the underlying law of negligence is governed by common law principles established by Donoghue v Stevenson [1932] AC 562 and its successors, together with the Consumer Protection Act 1987 Part I, which implements strict liability for defective products. The Occupiers’ Liability Acts 1957 and 1984 govern liability to lawful and other visitors.
For motor liability, the Road Traffic Act 1988 (RTA), particularly Part VI, sets out the compulsory insurance regime, and the Motor Insurers’ Bureau Agreements 1999 (uninsured) and 2017 (untraced) provide a fallback. The Civil Liability Act 2018 reformed the small claims regime for whiplash and personal injury and amended the Ogden Tables discount rate calculation regime.
Procedurally, casualty adjusters operate within the framework of the Civil Procedure Rules (CPR), particularly the Pre-Action Protocols for Personal Injury, Disease and Illness, Low Value Personal Injury (RTA), Low Value Personal Injury (EL/PL) and Professional Negligence. The MOJ Claims Portal handles low-value personal injury claims under £25,000.
The FCA’s ICOBS 8.1 claims-handling rules apply, as do Lloyd’s Minimum Standard MS11 for casualty business at Lloyd’s. The CILA Code of Conduct governs the casualty adjuster’s professional conduct, and case law such as Brown v GIO Insurance Ltd [1998] CLC 650 establishes the impartiality expected.
Significant case law that shapes casualty adjusting includes Wells v Wells [1999] 1 AC 345 on multipliers, Heil v Rankin [2001] QB 272 on general damages, Simmons v Castle [2012] EWCA Civ 1039 on 10% uplift, and the Mesothelioma Act 2014 on diffuse mesothelioma compensation.
A casualty adjuster’s caseload is typically smaller in number than a property adjuster’s but longer-running. A complex EL disease claim, a major construction negligence claim or a high-value D&O matter may run for five years or more. A typical caseload might consist of 20 to 60 claims at varying stages of investigation and litigation, with the adjuster acting as the case manager and insurer’s eyes and ears across each file.
The work cycle begins with notification, often by the policyholder or the policyholder’s broker. The adjuster will request the incident report, accident book, witness statements, CCTV, training records, safe-systems documentation, contracts of engagement and other primary evidence. They will then interview key witnesses, often with a court reporter or recording present, and may instruct an engineer or accident reconstructor. Where personal injury is alleged, the adjuster will obtain consent for medical records and instruct an independent medical examination by an appropriate consultant.
Quantum investigation is a substantial part of the work. The adjuster will analyse the claimant’s pre-accident and post-accident earnings, work history, pension entitlement, care and case management requirements, accommodation needs and assistive technology, applying the Ogden Tables and current discount rate to compute the multiplier-based future loss. Schedules and counter-schedules of loss are prepared, typically with the assistance of a forensic accountant on high-value cases.
The adjuster will also consider liability and policy issues: was the insured negligent, was the defendant in breach of statutory duty, was the loss in the course of employment, was the policy in force, was the duty of fair presentation met, and is there scope for contribution from another insurer or recovery from a third party. Reserves are set and revised throughout the claim’s life, with insurers expecting adjusters to provide robust narrative justifications.
Settlement may be reached by Part 36 offer, joint settlement meeting, mediation, or trial. The adjuster will typically attend joint settlement meetings and trial alongside defence counsel, providing technical support and recording outcomes.
Within the broad casualty specialism are several sub-disciplines. EL disease adjusters work on long-tail occupational disease claims including asbestos-related disease, occupational deafness, dermatitis and stress claims. They typically work closely with the ELTO database, with industrial disease specialist solicitors and with employer record archives. Many EL disease adjusters are highly experienced practitioners who have worked the same cohort of cases for decades.
PL and products adjusters investigate slip-and-trip, dog bite, food contamination, sports injury, leisure and product defect claims. Construction site claims involve the Construction (Design and Management) Regulations 2015 and frequently engage contractor and contractor’s insurer indemnity questions.
PI adjusters focus on professional negligence claims against solicitors, accountants, architects, surveyors, engineers, financial advisers and IT consultants. The role requires detailed understanding of professional standards and codes (such as those of the SRA, ICAEW, RIBA and RICS) and of the Civil Liability Act 2018. Many PI adjusters operate from London market specialists serving Lloyd’s syndicates and London company market underwriters.
D&O and management liability adjusters work on claims against company directors, with an increasingly international dimension following the introduction of the Corporate Governance Code and developments in shareholder litigation. Environmental liability adjusters specialise in pollution and contaminated land claims under the Environmental Damage Regulations 2015.
Casualty adjusters should be distinguished from claims handlers in insurer-internal claims teams. While both roles often share work, the casualty loss adjuster is typically engaged on more complex matters requiring independent investigation and CILA-grade technical input.
A national construction firm is sued by the family of a worker fatally injured when scaffolding collapsed on a city-centre redevelopment. The claim is brought under the Fatal Accidents Act 1976 and the Law Reform (Miscellaneous Provisions) Act 1934 on behalf of the deceased’s widow and three minor children. The insurer instructs a senior casualty loss adjuster with experience of fatal accidents.
The adjuster visits the site, interviews the scaffolding contractor, the site agent and the site manager, and instructs a forensic engineer to examine the failure mechanism. Reviewing the contract, the adjuster identifies that the scaffolding contractor was an independent contractor with its own EL/PL cover and that there is potential for contribution under the Civil Liability (Contribution) Act 1978. He obtains the HSE prosecution file and notes that breaches of the Work at Height Regulations 2005 have been admitted.
He instructs defence solicitors and a senior medico-legal expert in respect of the dependency claim. After 18 months he negotiates a settlement of £2.4 million, of which £1.6 million is recovered from the scaffolding contractor’s insurer by contribution proceedings. The adjuster’s final report sets out the indemnity decision, the liability analysis, the quantum calculation and the contribution outcome, providing the insurer with a complete record for audit and reinsurance recovery purposes.
