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 13 lots from 11 competitions run by 11 buyers, last 36 months. A buyer with many similar contests counts only up to a limit. All 13 lots are from Procurement Act 2023 notices, which count bids assessed.
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 70 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 12 decided competitions, last 36 months.
Only decided tenders count, so slow ones still waiting are not in.

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 3162. A notice with several codes counts in each sector it names. Notices from 2021 to 26 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.
