Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 71. The category anchor is Engineering services (71300000); 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 71	4,543	4 median · 28.7 average (1,400 of 4,543 with a bid count)	3.9 average (1,540 of 4,543 with named award suppliers)	Not published
Same buyer	0	Not published	Not published	Not published
Similar published value (0.5×–2×)	344	8 median · 14.6 average (5 of 344 with a bid count)	7.4 average (5 of 344 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.
