How Your Business Can Better Manage Rising Casualty/Personal Injury Costs

Managing Rising Casualty & Personal Injury Costs for UK Businesses

This article – part of a series which also explores key claims issues in motor, cyber and property – looks at the claims trends driving the casualty insurance market and the actions businesses should consider to help mitigate their risks and costs.

Key Takeaways
  1. Injury claims increase in number and value.
  2. Whiplash reforms and personal injury rule changes reduce the severity of low-value road traffic accident claims, but the process has become more complex.
  3. Sector-specific and social/legal pressures are raising liability risks, with businesses expected to do more around their duty of care.

Claims Costs Outpace Inflation 

Claims costs for serious injury continue to outpace general inflation in the UK. This is due to a combination of factors: wage inflation for carers and medical professionals, rising healthcare and rehabilitation expenses, and care requirements that are becoming increasingly complex due to evolving life expectancy. For serious bodily injury, care costs now represent the largest share of total compensation, often making up over 60% of total awards. 

These pressures are impacting Employers’ Liability (EL), Public Liability (PL) and insurers’ reserving, as well as their rate adequacy. There is increased scrutiny on assumptions around large losses, periodic payment orders (PPO) trends and life-care cost projections. Additionally, there is a growing interest in claims analytics, early intervention strategies and enhanced rehabilitation quality control.

What Your Business Should Consider
  • Stress-test budgets and retentions against higher long-term care costs.
    Serious injury claims, driven by care and medical costs, are outpacing general inflation. Test whether current deductibles, reserves and captives can absorb a single large loss under today’s cost assumptions.
  • Challenge and understand insurer/actuary assumptions.
    Ask your insurer to explain how they are allowing for wage inflation, trends in Periodic Payment Orders (PPOs), and changes in life expectancy are being built into pricing and reserving. Consider scenario analysis (e.g., higher care costs longer life expectancy) for your major loss exposures.
  • Invest in prevention, early intervention and rehabilitation quality.
    Focus on serious injury hotspots (e.g., high-risk tasks vehicle operations) and ensure rapid notification, triage and rehabilitation pathways are in place to improve outcomes and contain lifetime care costs.

Bodily injury inflation is creating new challenges for UK casualty programmes, but organisations are not powerless. Those that use data to understand claims, proactively review programme design and address emerging liabilities will be better placed to control costs, challenge structures and strengthen resilience.

Whiplash Reforms Reshape Injury Claims

The Whiplash Reform Programme, implemented by the UK government in 2021, continues to reshape the landscape of low-value RTA injury claims and broader personal injury matters. The small claims track limit for RTA personal injury has risen from £1,000 to £5,000. This means that legal costs are typically not recoverable for a larger number of minor injuries. The Official Injury Claim (OIC) portal is now mandatory for many low-value RTA claims, leading to an increase in litigants and added process-related friction for insurers. In 2025, following a statutory review, the whiplash tariff was increased by approximately 15% for accidents occurring on or after 31 May 2025, reflecting inflation since 2021.

Last year, the UK government initiated a post-implementation review of the reforms, seeking evidence on whether the frequency and cost of claims have fallen while, at the same time, access to justice is being preserved.

The structural severity of low-value road traffic accident (RTA) whiplash claims remains lower than before the reforms, although average damages have risen slightly due to the tariff uplift. Increased process complexity, driven by use of the OIC portal and more litigants, is adding to handling costs and cycle-time risks. 

For casualty underwriters, evolving benchmarks for pain and suffering in UK courts are influencing valuation expectations for slip/trip PL and EL minor injuries, and other low-level bodily injuries. 

What Your Business Should Consider
  • Review motor programme structure and realised savings.
    Ask your insurer or broker to demonstrate that your motor premiums, deductibles and limits reflect post reform experience and whether savings are being offset by higher handling and administration costs. Tighten OIC-related claims processes and governance.
    Agree clear service level agreements, escalation routes and communication standards with insurers/third party administrators (TPAs) for OIC claims, recognising increased litigants in person and the risk of longer cycle times.
  • Update valuation approaches for all minor injury claims.
    Ensure your EL/PL and minor injury settlement strategies use current tariff and court benchmarks for pain and suffering, so negotiations are consistent and defensible across all low-level bodily injury claims.

Discount Rate Environment Simplified but Large-Loss Costs Continue

According to Swiss Re’s 2025 Motor BI report, bodily injury claims costs continue to rise across Europe, despite regional legal and economic differences. In the UK, the introduction of a unified Personal Injury Discount Rate (PIDR) of +0.5% in January 2025 is expected to simplify lump-sum settlement calculations and modestly reduce settlement sizes compared to a negative rate environment.

The higher, unified PIDR may help moderate the costs of very large future care awards, which is positive for high-severity EL, PL, and motor bodily injury. However, wage and care-cost inflation partly offsets these gains, resulting in persistently elevated large-loss costs. Insurers and reinsurers are revising Ogden (future loss multiplier calculation tables) assumptions, and adjusting pricing and attachment points for excess casualty and reinsurance layers on buyers’ insurance programmes.

What Your Business Should Consider
  • Recheck limits and retentions.
    Use the new +0.5% PIDR as a trigger to review whether your EL/PL/motor limits, deductibles and aggregates still match your large loss exposure and risk appetite.
  • Update large loss modelling for real-world inflation.
    Refresh worst case injury scenarios to reflect today’s wage and care cost inflation (not historic assumptions), and test the impact on your balance sheet and captive/retention strategy.
  • Engage the market on structure, not just price.
    Talk to insurers and your broker about how Ogden/PIDR changes and inflation might affect excess layers and attachment points on your insurance programme and whether alternative structures and limits could offer better value.

Claimant Firms Get More Sophisticated but it’s Not Yet a ‘U.S.-Style’ Environment

Although “nuclear verdicts” are predominantly a U.S. phenomenon, the UK casualty market is seeing increased sophistication from claimant firms who are leveraging technology and marketing to aggregate claims such as data breaches, employment disputes and group actions. Regulatory and public scrutiny around workplace safety, harassment and environmental, social and governance (ESG) issues are also contributing to a rise in EL and Directors’ & Officers’ (D&O)-adjacent casualty claims — and a heightened focus on duty of care within supply chains, affecting products and general liability.

While the UK remains more controlled than the U.S. when it comes to jury awards, damages and class actions, the general trajectory is towards stricter expectations of corporate responsibility and greater willingness to litigate complex liability scenarios.

What Your Business Should Consider
  • Strengthen governance around duty of care and ESG.
    Review policies, training and oversight on workplace safety, harassment and ESG/supply-chain standards, as these are increasingly at the heart of EL, product and D&O‑adjacent claims.
  • Assess your exposure to group, collective and “mass” claims.
    Map where your business could face aggregated actions (e.g., data breaches, employment issues, product/consumer claims) and ensure both coverage and incident response plans reflect that risk.
  • Ensure your insurance and legal strategy reflect a tougher liability climate.
    Check that wordings, limits and defence arrangements are aligned with rising claimant sophistication and a greater willingness to litigate complex liability scenarios, even if the UK is not yet a US‑style environment.

Identifying Industry Specific Casualty Pressures

Distinct patterns are emerging across a wide range of industries in the UK:

Construction and infrastructure: Elevated EL claims are being seen due to falls, manual- handling and subcontractor management issues. Latent defect and construction-related product liability, such as cladding and fire safety, continue to pose long-tail concerns.

Healthcare and care providers: Rising exposures in care-home EL and medical malpractice are being exacerbated by staffing shortages and higher patient acuity.

Retail, leisure and hospitality: Slip/trip PL claims remain frequent but generally low in severity, although injury valuations are being affected by overall bodily injury inflation.

Tech/data-rich businesses: The overlap between professional, cyber and casualty lines is increasing as data-breach-related harms are framed as privacy or negligence-based bodily injury, including psychiatric injury.

What Your Business Should Consider
  • Map your sector’s key casualty pain points to your company’s operations.
    Identify where your business mirrors sector trends (e.g., falls from height in construction, slip/trip exposure in retail, malpractice in care, data‑related harm in technology) and prioritise controls.
  • Target risk improvement and capital spend where claims are emerging.
    Use recent incidents and near misses to help you decide where to invest. For example, in contractor management in the construction industry, staffing and training in care homes, housekeeping and flooring in retail and data governance in tech.
  • Check that your coverage reflects emerging cross‑line overlaps.
    For tech/data‑rich firms in particular, review how bodily/psychiatric injury from data or privacy events would respond across casualty, cyber and professional lines to avoid gaps or disputes.

Claims Teams Focus on Digitalisation, Fraud Focus and Talent 

Data and analytics are playing an increasingly important role for UK casualty claims functions. These tech-driven tools include automated triage, text analytics and risk scoring to flag potential fraud or organised claims activity – as well as likely large-loss cases – early for specialist handling. Despite reforms aimed at curbing opportunistic RTA fraud, insurers remain vigilant for evolving fraud patterns across different injury types and ancillary heads of damage.

Claims teams are also facing skills and capacity constraints, particularly in handling complex bodily injury and large-loss cases. This mirrors the broader shortage of skilled technicians and care workers contributing to claims-cost inflation.

What Your Business Should Consider
  • Ask how your insurers/TPAs use analytics on your claims.
    Understand whether automated triage, fraud scoring and early large loss identification are applied to your portfolio, and how you can share data to improve accuracy and outcomes.
  • Assess claims-handling capacity for complex injury cases.
    Talent shortages in injury claims handling can affect settlement quality and timelines. Confirm your partners’ resourcing for large loss and complex injury files, including escalation to specialist teams.
  • Align internal reporting with insurer digital tools.
    Standardise and improve the quality and timeliness of incident data you provide so digital tools (fraud analytics, severity prediction) can work effectively and support better pricing and negotiation.

How Insurers Are Responding

While the focus is on the claims environment, it is important to understand how insurers are responding. After significant pressure in 2022–2023, UK insurers, especially in the motor sector, returned to underwriting profit in 2024. However, margins will again be challenged as premium growth slows and claims inflation persists.

In casualty lines, insurers and reinsurers have been increasing rates and tightening terms for high-hazard liability and excess layers. There is greater attention to policy wording – specifically exclusions, aggregates and social-inflation-sensitive perils. Additionally, higher deductibles and co-insurance arrangements are being trialled to encourage insured behaviour and reduce attritional claims.

What Your Business Should Consider
  • Expect a continued focus on terms, not just price.
    With margins under pressure, insurers are likely to scrutinise exclusions, aggregates, limits and social inflation sensitive exposures. Be prepared to negotiate structure and wording, not just premium.
  • Use your own data story to differentiate your risk.
    High quality, segmented claims data (by sector, location, cause, injury type) can help you demonstrate control of casualty risk and secure more favourable pricing and capacity.
  • Regularly reassess limits, deductibles and co-insurance.
    As claims inflation and insurer appetite evolve, revisit whether current limits and retentions remain appropriate and whether alternative structures (e.g., higher deductibles, aggregates, co insurance) could deliver better value.

Inflation Persists for Bodily Injury Claims

The UK casualty market in 2025 is characterised by persistent bodily injury claims inflation, particularly fuelled by rising care and medical costs, despite some moderation in overall UK inflation. Whiplash reforms and personal injury rule changes continue to suppress low-value RTA claim severity but introduce greater process complexity, with 2025 seeing a 15% uplift in tariff values and a formal review of the reforms. The large-loss environment is more predictable due to the unified PIDR yet remains costly amid high wage and care-cost inflation. Sector-specific and social/legal pressures are raising liability risks, reflecting heightened expectations of corporate duty of care, though the market does not yet resemble the US “nuclear verdict environment. Finally, operational changes – digitalisation, fraud analytics, and talent shortages – are significantly shaping how UK insurers manage casualty claims.
