Professional services company Aon has expanded its proprietary Data Centre Lifecycle Insurance Programme (DCLP) by $1bn.

The expansion increases total available capacity to $2.5bn, at a time when risks across global data centre developments are becoming more complex.

The increase comes amid rapid growth in investment linked to cloud computing, AI and wider digital infrastructure, alongside the rising size and capital demands of modern data centres.

Launched in 2025, the DCLP is structured as a multi-line insurance solution covering projects from the construction phase through to ongoing operations.

It combines multiple risk categories that are typically insured under separate policies.

Aon president and CEO Greg Case said: “Managing risk throughout the data centre lifecycle is a strategic imperative – these platforms drive innovation, connectivity and economic growth. As these facilities become more critical and complex, building resilience into their infrastructure is essential for the broader business ecosystem.”

Under the programme, construction, cyber, cargo and operational exposures are brought together within a single insurance framework.

The approach is designed to allow clients to access large amounts of capacity more efficiently while reducing administrative complexity during project delivery.

The expanded programme is aimed at investors, developers and operators managing increasingly large and technically demanding data centre assets.

It pairs insurance capacity with risk engineering and analytics to support risk assessment and resilience planning across the full project life cycle.

Coverage under the DCLP includes up to $2.5bn for construction all risks, delay in start-up (DSU), and operational property damage and business interruption.

Cyber-related protection, including cyber property damage and technology errors and omissions, is available up to $400m.

It includes DSU cover for both damage and non-damage events, as well as business interruption and service-level agreement breaches.

In addition, the programme provides third-party liability insurance of up to $100m, excluding US exposures, and project cargo and transport cover of up to $500m.

Risk engineering and cyber impact modelling support are delivered through Aon’s Global Risk Consulting team.

Towards the end of last year, the company also renewed its client treaty, a follow-on facility offering multi-line protection for complex risks, with updated terms that include cover for extended construction timelines.

Together, the expanded DCLP and renewed client treaty are intended to support clients overseeing large technology projects from initial construction through to operational phases, with an emphasis on managing risk across the entire data centre life cycle.
