Benchmarked against retained Find a Tender procedures with CPV division 44. The category anchor is Miscellaneous fabricated products and related items (44400000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 44 | 2,660 | 6 median · 42 average (905 of 2,660 with a bid count) | 6.2 average (1,002 of 2,660 with named award suppliers) | Not published |
| Same buyer | 4 | Not published | Not published | Not published |
| Delivery region: UKD11 | 16 | 4 median · 5.2 average (5 of 16 with a bid count) | 1.8 average (5 of 16 with named award suppliers) | Not published |
| Similar published value (0.5×–2×) | 102 | 133 median · 133 average (2 of 102 with a bid count) | 20 average (2 of 102 with named award suppliers) | Not published |
“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
No planning milestones published.
No linked framework, prior procurement or reprocurement published.
Diagnostic view. “Not published” means this current release does not provide a value.

"riskDetails": "The safe retrieval and storage of Intermediate Level Waste (ILW) from the Magnox Swarf Storage Silo, one of the highest hazard facilities on the NDA estate, relies on bespoke 3m3 ILW boxes and their skips, which are integrated with existing legacy site infrastructure and designed to meet stringent safety, storage, transport and final disposal requirements. In previous contracts for the supply of 3m3 boxes, the difficulty of the required design materialised during, and jeopardised the performance of, those contracts. All Lot contracts in this Procurement will embed a New Product Introduction process which enables a phased approach to design and manufacturing in an attempt to address this known risk. However, this known risk could still jeopardise the performance of the contract and necessitate modifications to the Lot contracts.",

"description": "Please see below, information regarding a technical event being held by University of Sheffield/AMRC & Sellafield Ltd on the 20th of January 2026 relating to the Sellafield 3m3 Waste Containers. This event is purely a technical discussion regarding design and prototype method of manufacture. As such, no tender/commercial information will be shared or discussed. The aim of this forum is to establish the strengths and potential concerns of the latest 3m3 box design, while also gaining a clear understanding of the manufacturing methods that can be deployed.\nThere is a limited number of spaces available on the day and so we would suggest that no more than two representatives from each company attend to maximise benefit.\nAll information from this event will be shared on Atamis Ref: C26453 following the event taking place.\nFurther details and ticket reservation can be found following the below links:\nMorning Session: https://www.eventbrite.co.uk/e/technical-market-engagement-forum-tickets-1978290009673\nAfternoon Session: https://www.eventbrite.co.uk/e/technical-market-engagement-forum-tickets-1978291841151?aff=oddtdtcreator\nReservations can only be made using the links above."
