Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 45. The category anchor is Demolition work (45111100); 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 45	9,062	4 median · 25.3 average (2,031 of 9,062 with a bid count)	3.7 average (2,230 of 9,062 with named award suppliers)	Not published
Same buyer	16	Not published	Not published	Not published
Delivery region: UKM61	11	304 median · 304 average (2 of 11 with a bid count)	30.5 average (2 of 11 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.
