Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 45. The category anchor is Mechanical engineering installation works (45351000); 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 457,9253 median · 21.5 average (1,517 of 7,925 with a bid count)3.5 average (1,673 of 7,925 with named award suppliers)Not published

Delivery region: UKM6354 median · 54 average (13 of 35 with a bid count)10.2 average (18 of 35 with named award suppliers)Not published
Similar published value (0.5×–2×)7276 median · 10.8 average (9 of 727 with a bid count)4.4 average (9 of 727 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.
