Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 33. The category anchor is Functional support (33180000); 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 332,7412 median · 114.4 average (1,102 of 2,741 with a bid count)6 average (1,310 of 2,741 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.
