What is being bought
United Kingdom National Nuclear Laboratory is undertaking pre-market engagement to inform the development of a Fabrication and Machining framework, structured as a multi-lot arrangement to support both nuclear and non-nuclear requirements. The framework is intended to provide access to suitably qualified suppliers, capable of delivering a range of fabrication and machining services, which may include (but are not limited to): - precision machining; - coded welding; - specialist fabrication; - component manufacture; - repair and modification activities; - associated quality, inspection and documentation services.

Comparable-procurement analytics
Benchmarked against retained Find a Tender procedures with CPV division 42. The category anchor is Nuclear reactors and parts (42150000); 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 42 | 855 | 4 median · 72.9 average (168 of 855 with a bid count) | 5.8 average (177 of 855 with named award suppliers) | Not published |
| Same buyer | 5 | Not published | Not published | Not published |
| Delivery region: UKC | 47 | 1 median · 12.9 average (9 of 47 with a bid count) | 3 average (9 of 47 with named award suppliers) | Not published |
| Similar published value (0.5×–2×) | 74 | 2 median · 2 average (1 of 74 with a bid count) | 1 average (1 of 74 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.
Price-outcome signal
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.
