Insurance insights: Casualty, Summer 2026

20 July 2026

This edition brings together four articles covering significant legal developments across litigation, costs and regulatory compliance, each with direct implications for insurers' claims handling, underwriting and risk management strategies.

We address the following:

The conclusion of the long-running child sexual exploitation litigation in EGZ v Hertfordshire County Council and others, and the lessons it offers for the management and evidential preparation of CSE claims.
The new 25% cap on recoverable MRO mark-ups established in JXX v Archibald, and the practical steps insurers should take to embed this benchmark into costs challenge and reserving strategies across personal injury and clinical negligence portfolios.
The statutory obligations introduced by Martyn's Law ahead of its anticipated commencement, and the implications for insurers writing property, liability, terrorism and management liability cover.
The latest judicial developments on fundamental dishonesty in personal injury claims, including key guidance on subjective belief, the deployment of surveillance evidence, the scope of the dishonesty threshold and the costs consequences where dishonesty is found on both sides.

Together, the articles reflect the range of legal and regulatory change with which insurers must engage, spanning claims strategy, costs management, underwriting and compliance across a broad range of liability lines.
