i
Tenders you can still bid for.
Notices at tender stage whose deadline has not passed, counted the way the search counts them: a notice shows under every code and region it names.
i
Notices published in the last 12 months.
Counted per tender, not per lot, against the 12 months before where shown.
i
How many companies usually bid for a lot here.
The middle value of the bid counts that award notices publish, one per lot. Only real competitions count: direct awards and framework places are left out.
Based on 76 lots from 65 competitions run by 62 buyers, last 36 months. A buyer with many similar contests counts only up to a limit. 37 lots are from Procurement Act 2023 notices (bids assessed, middle 3) and 39 from older notices (bids received, middle 4).
i
What a contract here is usually worth.
Middle value of published award values, VAT excluded. Framework ceilings are left out because they are not real contract values.
Based on 282 awards with a usable value, last 36 months.
Published values, not actual spend.
i
How long buyers here take to decide after bids close.
Middle value in days from the bid deadline to the award date, on competitions that published both.
Based on 38 decided competitions, last 36 months.
Only decided tenders count, so slow ones still waiting are not in.

i
How many companies usually bid for a lot here.
The middle value of the bid counts that award notices publish, one per lot. Only real competitions count: direct awards and framework places are left out.
Based on 76 lots from 65 competitions run by 62 buyers, last 36 months. A buyer with many similar contests counts only up to a limit. 37 lots are from Procurement Act 2023 notices (bids assessed, middle 3) and 39 from older notices (bids received, middle 4).
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.
138 of 341 notices that state a procedure, last 36 months. 43 more give no procedure and are left out.
i
What share of bids come from small and medium firms.
SME bids divided by all bids, on lots where the buyer published the split.
195 SME bids out of 248, on 61 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.
129 of 208 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 47 lots with both an estimate and an award, last 36 months.
A past pattern, not a price to bid.
i
How often a tender ends with no award.
Notices cancelled, withdrawn or marked unsuccessful, plus terminated ones that never got an award.
9 of 384 notices, last 36 months.
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 24 lots from 10 framework and DPS notices, last 36 months.

About this data
- Source. Official UK public procurement notices (Find a Tender), reused under the Open Government Licence v3.0. New notices arrive through the day; the figures are rebuilt nightly.
- What counts here. Every notice with a CPV code starting 51, on the tender or any of its lots. A notice with several codes counts in each sector it names. Notices from 2021 to 29 Oct 2026.
- Competition. Bids and winners cover the last three years and count each lot as its own contest; frameworks and dynamic purchasing systems are shown apart from ordinary contracts.
- Why no total spend. Notice estimates often repeat a framework’s ceiling, so adding them up would overstate the market. Typical contract values are shown instead.
- Every figure shows what it rests on. Not every notice publishes a bid count, a value or a delivery region, so each figure carries the number of records behind it, and one built on few records is marked as such. The on a figure explains it; the counting rules are in the methodology. Spotted something wrong? Tell us.
