## Summary

Sellafield Ltd procured major building refurbishment works for the Fuel Handling Plant and Site Ion Exchange Effluent Plant buildings in the North West of England. The project covers replacement of approximately 28,500 square metres of roof, equivalent to about five acres, with a new maintainable roofing system. Its purpose is to support safe ongoing operations for personnel and operational systems through to 2060/70. The procurement is categorised as building construction work (CPV 45210000) and falls within the works category. It is relevant to contractors with the capability to deliver large-scale industrial roofing replacement and refurbishment in an operational nuclear-site environment, including the associated planning, construction and maintainability requirements.

The procurement is complete and has been awarded. Sellafield Ltd used a selective call-off from a framework agreement, with the tender deadline having been 30 April 2026 at 12:00. Morgan Sindall Construction & Infrastructure Ltd received the active award on 24 August 2026 for £35,000,000. The awarded contract runs from 24 August 2026 to 10 January 2031. The procurement was assessed as unsuitable for SMEs and voluntary, community or social enterprises. The published outcome identifies one supplier and one awarded requirement. The award therefore records the route, scale and delivery period for a substantial industrial roof refurbishment project rather than an unawarded opportunity.

This procurement is commercially relevant to large construction and specialist roofing businesses able to deliver extensive refurbishment works across major industrial buildings. A credible future competitor would need proven capacity for projects covering tens of thousands of square metres, together with the resources to manage a multi-year programme and provide a maintainable roofing solution. Experience of working safely around operational plant, personnel and critical operating systems would be important for this type of requirement. The use of a framework call-off and selective route also indicates that access to an appropriate framework, or partnership with an established framework contractor, can be commercially significant. The selected supplier’s large-company scale reinforces the need for substantial delivery capability and organisational capacity.
