Marsh Risk, an insurance broker, risk advisor, and a business of Marsh, has added significant capacity to Nimbus, its large-scale data centre construction insurance facility, which now offers limits of up to $2.7 billion, including delay in start-up and business interruption coverage, for major projects across the UK, US, Canada, Europe, Australia, and New Zealand.
Marsh Risk launched Nimbus in June 2025 as the “first insurance facility of its kind” for large-scale data centre construction projects.
The facility supports digital infrastructure development while reducing key risks and offering stronger financial protection for Marsh Risk’s clients and their capital providers.
Nimbus is currently being deployed on numerous projects in the US, UK, and the Netherlands.
Mike Mathews, Global Digital Infrastructure Leader, Marsh, commented, “Demand for more powerful and efficient data centres is accelerating technological innovation, particularly around AI and machine learning, which will revolutionise the way we live and work and reshape economic landscapes over the next decade.
“Marsh is helping clients in this sector work with communities to develop business strategies that will enable them to grow sustainably.
“By harnessing our global resources in critical interconnected areas such as capital management, construction, off-site power generation, environmental risk, and operational resilience, Marsh is enabling data centre developers, operators, and owners to strengthen their delivery and resilience as we embrace the age of Industry 4.0.”
Beyond providing substantial London market capacity through A-rated insurers, Marsh’s Global Digital Infrastructure team offers expertise in construction, cybersecurity, energy, and power to help clients protect capital, manage assets, and expand.
