i
How much of this market is actually put out to competition.
Notices run as an open or selective procedure, out of all notices that say which procedure was used. Direct awards count as not competed.
339 of 399 notices that state a procedure, last 36 months. 97 more give no procedure and are left out.

What share of bids come from small and medium firms.
SME bids divided by all bids, on lots where the buyer published the split.
341 SME bids out of 544, on 117 lots where the buyer published the split.
i
What share of contracts go to small and medium firms.
Awards to a single supplier that declared its size. SME divided by all.
100 of 197 awards where the winner declared its size.
i
How much work here goes to companies based in the region.
Contract awards where the winner’s registered address is in this region, out of awards where the address is known.
Registered address, so a national firm with a local branch counts as outside.
i
Do winners come in above or below the buyer’s estimate.
For each lot we compare the published estimate with the award, like for like. Below means the winner was paid less than estimated, above means more.
Based on 109 lots with both an estimate and an award, last 36 months.
A past pattern, not a price to bid.

Only what buyers published. Tenders that quietly went nowhere are not counted.
i
How many companies apply to get onto a framework or DPS here.
Middle value per lot, frameworks and dynamic markets only. Getting onto a panel is not the same as winning work, so it is kept separate.
Based on 296 lots from 102 framework and DPS notices, last 36 months.

What the numbers on this page are and are not
Which notices count?
Every Find a Tender notice that carries a CPV code starting 7135. A notice with several codes counts in each sector it names. Earliest notice 2021; latest 21 Sept 2026.
Competition figures
Lot-grain contest statistics over the last 36 months: a lot counts where its own CPV codes (or, for single-class notices, the procedure’s) start 7135; contracts and frameworks / DPS are kept apart. Each figure’s own method — grain, window, exclusions and this page’s sample — is behind its ; the long form is on Methodology.
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.
