Reserving

Overview

Where expertise meets experience

Reserves are fundamental to any insurer’s financial strength, acting as a critical lens for assessing business performance and managing a constantly evolving risk landscape. As complexities in underwriting and claims grow, effective reserving is essential for meeting strategic objectives and sustaining market confidence.

At Milliman, reserving is a core component of our consultancy services. Whether we’re providing Statements of Actuarial Opinion (SAOs), delivering independent reserve reviews, or partnering to build an in-house reserving operation, our team brings both deep actuarial knowledge and practical insights that power better decision-making. Leveraging advanced modelling and proprietary software, we streamline processes, enhance data quality, and reduce risk exposure. Our global team has extensive experience across the UK, including within Lloyd’s and other major markets worldwide.
