The global data centre sector continues to expand at extraordinary speed, driven by cloud computing, artificial intelligence and the growing volume of data generated and processed by businesses worldwide. However, as facilities become larger, more valuable and increasingly interconnected, the risks associated with them are also changing.

Recent industry analysis has highlighted a growing challenge: insurance programmes designed for more conventional data centre risks may not adequately reflect the scale, concentration and interdependency of today’s hyperscale developments.

Increasing concentrations of risk

The values concentrated within individual data centre sites have risen substantially. At some hyperscale facilities, insured values can reach US$20 billion to US$50 billion at a single location.

This is not simply a question of larger buildings. Modern data centres combine highly valuable computing equipment with sophisticated cooling infrastructure, battery systems, power generation and distribution equipment, fibre connections and other critical systems.

AI infrastructure is adding further complexity. High-performance computing equipment can require considerably greater power and cooling capacity than conventional data centre technology, while the financial consequences of an interruption can be substantial.

The result is a highly concentrated risk environment in which the failure of one system can have consequences extending well beyond the initial physical damage.

Construction and operation are increasingly overlapping

Data centre campuses are frequently developed in phases. One building or hall may already be operational while another is being constructed, commissioned or expanded elsewhere on the same site.

This creates an important insurance consideration.

Construction All Risks (CAR) cover and operational Property and Business Interruption programmes may need to operate alongside one another, with the risk profile continually changing as individual phases are completed and brought online.

The transition from construction to operation therefore requires careful attention. Testing and commissioning can itself represent a significant exposure, particularly where new electrical, cooling and power systems are being integrated into an operational environment.

Clear policy boundaries, appropriate limits and a detailed understanding of when responsibility transfers between programmes can help reduce the potential for gaps or uncertainty following a loss.

One incident can affect several classes of insurance

Perhaps the defining characteristic of modern data centre risk is interdependency.

A single incident may potentially affect Property Damage, Business Interruption, Construction, Cyber, Machinery Breakdown and Liability covers.

For example, a power disturbance could damage equipment, interrupt operations and delay the commissioning of a new facility. A cooling-system failure could result in physical damage while simultaneously disrupting services relied upon by multiple organisations.

Where different elements of the exposure are insured under separate policies, it becomes increasingly important to understand how those policies interact.

Reviewing limits, exclusions, triggers and indemnity periods across the entire programme can therefore be just as important as considering each policy individually.

Addressing SLA exposure

Data centre operators can also face significant financial exposure through Service Level Agreements (SLAs), with downtime potentially resulting in rent credits, rebates or other contractual penalties. Parametric insurance can help address this exposure by providing cover based on predefined, objectively measurable triggers, such as power, cooling or connectivity thresholds, rather than relying on a traditional loss assessment.

Cover can be structured to reflect the downtime thresholds and financial commitments within individual SLAs, providing rapid liquidity when an agreed trigger is met. This can help protect cash flow, reduce the need to hold significant reserves against SLA commitments and complement traditional Property Damage and Business Interruption insurance.

Power is becoming a critical consideration

Reliable power has always been fundamental to data centre operation, but the scale of current and planned developments is making energy availability an increasingly significant issue.

AI-intensive facilities in particular can require enormous quantities of electricity. At the same time, operators are exploring a wider range of on-site and alternative energy solutions, including renewable generation, battery energy storage systems and other forms of distributed generation.

These arrangements can improve resilience and help address grid constraints, but they can also introduce additional construction, operational and equipment exposures.

For insurance purposes, the data centre and its energy infrastructure increasingly need to be considered as interconnected parts of the same risk rather than separate assets.

Emerging liability and environmental exposures

The risk landscape also extends beyond physical assets.

As development accelerates, data centre projects are facing greater scrutiny around planning, environmental impact, water consumption, energy use, noise and the operation of cooling and backup generation equipment.

Recent analysis indicates that major data centre lawsuits and arbitrations increased substantially between 2021 and the first half of 2026, with planning, zoning and environmental disputes accounting for much of the recent growth.

These exposures can continue long after construction has finished, making liability considerations an increasingly important component of long-term risk management.

Building insurance around the complete data centre lifecycle

As data centres become larger and more complex, insurance arrangements need to evolve with them.

Rather than treating construction, operational property, power generation, cyber and liability exposures in isolation, organisations should consider how risks interact throughout the lifecycle of a facility, from initial construction and commissioning through to full operation and subsequent expansion.

At W Denis, our specialist teams provide insurance and risk management solutions across the data centre lifecycle, including the associated power generation and energy infrastructure on which modern facilities increasingly depend.

Through access to UK and international insurance and reinsurance markets, we can help organisations assess complex and high-value exposures and structure programmes designed around the specific characteristics of their operations.
