Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 50. The category anchor is Aircraft maintenance services (50211100); 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

“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.

In your expression of interest, please indicate your preferred duration of any potential future contract.\nThis PMEN has been published for the purposes of Market Sounding and to assist in the determination of the procurement strategy. No formal procurement has been launched. This is not a commitment by the UK Ministry of Defence to place a contract or launch a tender in the future.\nSuppliers that express an interest but do not currently hold the required regulatory approvals or certifications are encouraged to engage with the Authority. The Project Team will provide information and guidance on the processes and requirements to obtain the necessary approvals, to support fair and open competition and to minimise barriers to entry.
