## Summary

Nuclear Restoration Services Limited procured works at Wylfa for the development, fabrication and installation of a mezzanine platform and containment enclosure, including a transit route in the Sprocket Room. The requirement covers both engineering design and physical construction and installation, rather than the supply of standalone equipment. The work is associated with the buyer’s nuclear restoration activities and is to be delivered at the Wylfa site. The classification is engineering and construction works (CPV 45220000). This opportunity is therefore relevant to engineering contractors, fabricators and installation businesses able to deliver bespoke structural platforms, enclosed transit arrangements and associated site works as one integrated package.

The procurement is complete and the contract was awarded to Penny Engineering Ltd. It used a below-threshold limited competition. There was one completed lot covering the full requirement. The contract was signed on 18 August 2026 and has a gross value of £165,570. It runs from 27 August 2026 to 27 November 2026. The award is active and the contract is active. The published outcome shows a single supplier for the works. Evaluation details are not set out in the available process information, so the key commercial signals are the limited-competition route, the requirement for an integrated design, fabrication and installation solution, and the defined delivery period at Wylfa.

For suppliers that did not win, this award demonstrates a defined requirement for bespoke engineering and construction work within Nuclear Restoration Services’ estate. A credible competitor for a future requirement would need to combine design development, fabrication and site installation, with the practical capability to create a mezzanine platform, containment enclosure and transit route around an existing industrial room. Relevant businesses are likely to be engineering contractors or specialist fabricators with sufficient operational capacity to manage a complete works package rather than a single trade element. Experience coordinating design, manufacture and installation on technically constrained sites would strengthen a supplier’s position, particularly where containment, access, transit arrangements and safe construction sequencing affect delivery.
