Last 36 months.

Buyer: 6 of 20 known-size awards · market: no supplier sizes published
30%—

Small firms have won here. Neither number says whether you qualify; it describes who has been winning.

How often do local suppliers win?
i

40%—

Most of this buyer’s recorded winners are registered outside the delivery region.

How long to a decision?

How long buyers here take to decide after bids close.

Middle value in days from the deadline to the first award notice, on competitions that published both dates.

Only decided tenders count, so slow ones still waiting are not in.

Last 36 months.

Buyer: 9 decided notices · market: no decision dates published
83 days—

Half of these awards were announced within 83 days of the bid deadline.

How often single-bid or direct?

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.
  • Two views, kept apart. The authority’s own track record and the wider market for the same kind of work sit side by side and are never mixed. Where the local picture is too thin, a figure widens to a broader market and says which one it used.
  • Forecasts are labelled. The price forecast and its range, possible competitors and the earlier-work matches are our estimates from past awards: not published facts, not win chances and not price advice. Official notices do not say who is bidding.
  • 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.
