UK's Costain gets up to $1.3 billion nuclear utilities contract

Costain will upgrade utility systems over up to 15 years supporting Sellafield’s nuclear decommissioning, part of a £2.9 billion infrastructure program at the site.

  • Recently, Costain was chosen as Sellafield’s Utilities Delivery Partner under the Infrastructure Delivery Partnership, part of a long-term programme valued at up to £2.9 billion running into the 2040s.
  • Sellafield Ltd created the IDP to replace the Infrastructure Strategic Alliance and consolidate suppliers amid a long, complex decommissioning programme needing reliable non-nuclear infrastructure.
  • Costain will deliver detailed design, procurement, installation, construction, commissioning, and handover for utilities upgrades, covering steam, water supply, water treatment, and compressed gas, building on its Sellafield relationship since 2005 and contracts at Sizewell C and Urenco this year.
  • Investors pushed Costain’s shares up 8.7% Monday after the company announced the long‑term Sellafield contract, while all contractors committed to Sellafield Ltd’s Social Impact strategy including local employment and apprenticeships.
  • Alongside Costain, Morgan Sindall Infrastructure and HOCHTIEF will operate under the IDP, with Morgan Sindall taking electrical distribution and HOCHTIEF overseeing a 595m civils lot, emphasizing regional benefits.
