Summary of the contracting process

Sellafield Limited is initiating the procurement process for the Magnox Swarf Storage Silos (MSSS) Boxes, a project estimated at a gross value of £114 million. This planned procurement falls under the industry category of containers for waste material and miscellaneous fabricated products. Located in the UK, specifically in the UKD11 region, the procurement stage is currently at the planning phase, with a future notice date anticipated by 3rd April 2026. Companies should note that the formal contract is scheduled to commence on 2nd April 2027 and will run until 1st April 2032. Sellafield Limited, a public authority under sub-central government classification, manages this procurement, promising a substantial opportunity for suppliers dealing in goods, particularly if they cater to waste material management.

This tender offers significant prospects for businesses looking to engage with public sector projects, particularly those specialising in the production of storage and waste management solutions. Given the scale and duration of the contract, small and medium-sized enterprises (SMEs) are noted for their suitability to participate. Firms with expertise in manufacturing containers and fabricated products are poised to benefit, as they can leverage this opportunity to bolster their market position and expand their reach into government contracts. The procurement method underscores a structured tender process, ideal for businesses aiming to develop long-term partnerships within the nuclear and waste management sectors.
