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 35 lots from 31 competitions run by 26 buyers, last 36 months. A buyer with many similar contests counts only up to a limit. 30 lots are from Procurement Act 2023 notices (bids assessed, middle 3) and 5 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 88 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 30 decided competitions, last 36 months.
Only decided tenders count, so slow ones still waiting are not in.

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 35 lots from 31 competitions run by 26 buyers, last 36 months. A buyer with many similar contests counts only up to a limit. 30 lots are from Procurement Act 2023 notices (bids assessed, middle 3) and 5 from older notices (bids received, middle 4).

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.

45 of 74 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 27 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.
7 of 152 notices, last 36 months.
Only what buyers published. Tenders that quietly went nowhere are not counted.

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 4524. A notice with several codes counts in each sector it names. Notices from 2021 to 23 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.
