Following a competitive procurement process, Sellafield Ltd has awarded HOCHTIEF (UK) Construction and two other companies contracts with a total value of up to £2.9bn.
HOCHTIEF (UK) Construction will deliver a major nuclear and civil works framework contract worth up to £595 million (EUR 685M) as part of the Infrastructure Delivery Partnership (IDP) at the Sellafield site.
The contract, lasting up to 15 years (an initial 9 years with an option of a further 6), involves design, engineering, and delivery of civil infrastructure works in support of nuclear operations and decommissioning in collaboration with Sellafield and its partners.

Juan Santamaría Cases, CEO of HOCHTIEF:
“Securing this strategic, long-term partnership reinforces HOCHTIEF’s unbroken legacy in the nuclear sector since the 1950s – a trusted partner in engineering and construction for some of the world’s most critical nuclear programmes. Together with Sellafield and its delivery partners, we are committed to delivering the robust infrastructure essential to this nationally significant mission, while fostering sustainable growth and opportunity for the people of West Cumbria and beyond. This award builds on HOCHTIEF’s expanding portfolio of long-term delivery contracts with globally significant clients across the nuclear and infrastructure sectors – customers who are shaping the future, and choosing HOCHTIEF to help build it.”
James Riddick, Sellafield Ltd chief supply chain officer, said:
“Our job at Sellafield is to create a clean and safe environment for future generations. That means safely, securely, and cost effectively dealing with the legacy of historic operations on our site. To deliver this we need robust and reliable infrastructure to support our nuclear decommissioning and waste management activities. IDP is a long-term strategic partnership designed to provide that support while unlocking investment and opportunities for our local community and delivering sustainable value for money to the taxpayer. We’re excited to welcome our new partners, and we look forward to working together to progress our mission while creating transformational and enduring social value.”
The award reflects HOCHTIEF’s strong engineering capability, proven track record in the nuclear and infrastructure sectors, and commitment to collaborative and secure delivery and is focused on resilient and sustainable outcomes in West Cumbria.
This important project win builds on HOCHTIEF’s long-standing expertise in the UK major civils and infrastructure sector and significant role in the construction and decommissioing of nuclear facilities around the world over the past 60+ years. The award reinforces HOCHTIEF’s strategic commitment to supporting the UK’s nuclear industry and its supply chain. The project financing follows a standard industry structure, combining equity, partnership models, and debt financing, supported by targeted EU funding.
