Both HOCHTIEF and Sellafield leaders emphasized that the partnership represents a commitment to sustainability, safety, and community growth, reinforcing HOCHTIEF’s six-decade legacy in nuclear infrastructure development. The framework aims to deliver reliable, efficient, and future-proofed infrastructure solutions aligned with the UK’s clean energy and decommissioning ambitions.

(PRESS RELEASE) MADRID, 13-Oct-2025 — /EuropaWire/ — Sellafield Ltd has appointed HOCHTIEF (UK) Construction as one of three delivery partners in a major framework valued at up to £2.9 billion, following a rigorous competitive procurement process. Under the agreement, HOCHTIEF will manage a nuclear and civil engineering framework worth as much as £595 million (EUR 685 million) as part of the Infrastructure Delivery Partnership (IDP) programme at the Sellafield nuclear site in Cumbria.

The partnership, set to run for an initial nine years with an option to extend for another six, focuses on the design, development, and implementation of essential civil infrastructure required to sustain nuclear operations and accelerate decommissioning. Working alongside Sellafield and other strategic partners, HOCHTIEF will contribute to modernising one of the UK’s most critical industrial sites while supporting long-term environmental and social objectives.

Juan Santamaría Cases, CEO of ACS Group and HOCHTIEF, highlighted the company’s continued commitment to the nuclear sector: “This contract reinforces HOCHTIEF’s enduring role in nuclear engineering since the 1950s. Our partnership with Sellafield Ltd builds on a legacy of innovation, safety, and technical excellence. Together, we will deliver the resilient infrastructure that underpins this national mission, creating local employment and driving sustainable regional growth.”

James Riddick, Chief Supply Chain Officer at Sellafield Ltd, underscored the strategic impact of the collaboration: “At Sellafield, our responsibility is to manage the legacy of the UK’s nuclear past safely and sustainably. Achieving that vision demands robust infrastructure and trusted partners capable of delivering complex projects efficiently. The Infrastructure Delivery Partnership allows us to do this while generating meaningful economic and social value for West Cumbria and the wider UK.”

The new framework underlines HOCHTIEF’s strong engineering expertise and its capacity to deliver highly secure, large-scale projects in the energy and infrastructure sectors. By joining forces with Sellafield’s existing delivery ecosystem, the company aims to support the UK’s nuclear transition through collaboration, innovation, and community investment.

With a history spanning more than 60 years in the design, construction, and decommissioning of nuclear facilities worldwide, HOCHTIEF continues to expand its UK footprint through long-term, high-value partnerships. The project’s financing structure combines equity, partnerships, and debt models backed by targeted EU funding, ensuring both stability and alignment with national sustainability goals.
