How we work this out
Open tenders, planned tenders and awards come from Find a Tender and Contracts Finder (Open Government Licence v3.0). “Bids” is the median number of bids on the buyer's earlier open tenders (Find a Tender, 2025-26). It describes the buyer's history, not this tender, and is not a forecast. Contracts ending are from award notices and may be extended or re-tendered early or late. Always check the official notice.
