Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 34. The category anchor is Railway and tramway locomotives and rolling stock and associated parts (34600000); 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 setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 342,3943 median · 22.9 average (819 of 2,394 with a bid count)3.4 average (904 of 2,394 with named award suppliers)Not published
Same buyer126 median · 6 average (1 of 12 with a bid count)1 average (1 of 12 with named award suppliers)Not published
Delivery region: UKC1103 median · 14.1 average (36 of 110 with a bid count)2.7 average (41 of 110 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.
