Benchmarked against retained Find a Tender procedures with CPV division 71. The category anchor is Energy and related services (71314000); 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 | 7,292 | 4 median · 30.7 average (2,704 of 7,292 with a bid count) | 4.1 average (2,996 of 7,292 with named award suppliers) | Not published |
| Same buyer | 2 | Not published | Not published | Not published |
| Delivery region: UK | 1,665 | 4 median · 64.8 average (568 of 1,665 with a bid count) | 6.9 average (647 of 1,665 with named award suppliers) | Not published |
| Similar published value (0.5×–2×) | 263 | 53 median · 53 average (2 of 263 with a bid count) | 12.5 average (2 of 263 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.
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.
No planning milestones published.
No linked framework, prior procurement or reprocurement published.
Diagnostic view. “Not published” means this current release does not provide a value.
