Which notices count?
Every Find a Tender notice that carries a CPV code starting 3117. A notice with several codes counts in each sector it names. Earliest notice 2021; latest 18 Sept 2026.
Competition figures
From the 36-month lot-grain contest statistics: a lot counts where its own CPV codes (or, for single-class notices, the procedure’s) start 3117. Bids per lot come from the award notice’s bid statistics; “competed” means an open or selective route with no direct-award transparency notice; contract values are net, on single-supplier awards, with framework and DPS ceilings excluded. Frameworks and dynamic purchasing systems are reported separately because their “bids” are admissions to a panel.
Why no total value or month-by-month chart?
Sums of notice estimates repeat framework ceilings and mix net with gross. Monthly volumes per sector are not shown yet: the catalogue’s CPV coverage per notice changed in May 2026 (compiled records carry every lot’s codes), so a curve would show the catalogue, not the market.
