Insurer Markel International and broker Willis have introduced a dedicated insurance facility to deliver capacity for the nuclear sector. The solution is designed to provide end-to-end capacity for nuclear facilities, a move that the firms say signals growing confidence in nuclear energy's role in the global energy transition, as the sector’s insurance needs become more complex.

The facility will offer property damage and business interruption cover spanning both nuclear-critical and conventional exposures, across the full lifecycle of a project, from construction through to operation. Capacity can be deployed on a quota share or excess of loss basis, giving clients flexibility in how they structure their programmes.

Recent industry analysis highlights renewed investment in nuclear energy, supported by a significant pipeline of new nuclear capacity. The World Nuclear Association reports that around 70 reactors are currently under construction globally, with more than 100 more planned.

Rohan Davies, managing director, London Market at Markel International, said: “With renewed global momentum behind nuclear, driven by the transition to low-carbon energy and increasing demand from data centres and AI, the sector is entering a new phase of growth and demands a step change in how the insurance market responds.

“This joint facility with Willis is our answer to that: tailored, specialist capacity structured for the complexity of modern nuclear projects, built for an era when the stakes and the scale are higher than ever.”
