UK7 - Contract Details Notice
Summary of the contracting process

Nuclear Restoration Services Limited procured the design, manufacture and installation of a contamination enclosure at the Wylfa Site in Anglesey. This is construction and building-installation work supporting contamination control within a nuclear restoration environment. The requirement covers the complete enclosure solution rather than a separately stated supply or installation package. The buying organisation is a public authority responsible for nuclear restoration activities, and the delivery location is Wylfa Site, Anglesey. The relevant classification is CPV 45300000, covering building installation work. The requirement is therefore most relevant to businesses able to design, manufacture and install specialist enclosed structures for controlled or contaminated operational settings, particularly those with experience working at nuclear or similarly regulated industrial sites.

The procurement has been awarded and the tender is complete. It used a direct award below the applicable threshold, without competition. Rubb Buildings Ltd was selected as the supplier for the single lot. The contract was signed on 18 August 2026 and runs from 3 September 2026 to 8 March 2027. Its gross value is £368,691.56. The contract is active. The outcome indicates that Nuclear Restoration Services Limited placed the requirement with one supplier rather than running a competitive tender. The evaluation basis was therefore the direct-award route, with no competitive award criteria or tender evaluation details recorded. This was a works procurement for the full design, manufacture and installation requirement at Wylfa.

This award shows demand from Nuclear Restoration Services Limited for a complete contamination-enclosure capability at the Wylfa Site. A credible future competitor would need to combine structural or enclosure design, controlled manufacture and on-site installation, rather than provide only one element of the work. Relevant businesses are likely to include specialist building and temporary-structure manufacturers, nuclear-sector contractors, and industrial installation firms able to coordinate design through commissioning. Experience of contamination-control environments, working safely on nuclear sites and managing installation in operational or restricted settings would strengthen a supplier’s position, although the procurement does not state specific accreditations or minimum experience requirements. The selected supplier’s involvement also demonstrates that established specialist enclosure providers can meet this buyer’s requirement through a below-threshold direct-award route.
