How the contest usually goes

Winner shares use published awards; bid and price charts use contested lots.

Question for the bid
This buyerWestminster City Council · all categories
What to do with it
How often do SMEs win?
i

How often small and medium firms win.

Share of awards where the winner’s size is known.

The counts under this question show how many awards have a known supplier size.

Last 36 months.

Buyer: 107 of 176 known-size awards · market: CPV 3812 · UK-wide, n=10
61%50%

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

How often do local suppliers win?
i

How often local firms win similar work.

Winners with a registered address in the delivery region, out of awards with a known address.

Here, local means the winner is registered in the region where that contract was delivered.

A local branch does not count if the registered address is elsewhere.

Last 36 months.

Buyer: 99 of 161 known-location awards · market: CPV 3812 · UK-wide, n=18
61%17%

Most of this buyer’s recorded winners are registered in Greater London.

How long to a decision?
i

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: 29 decided notices · market: division 38 · Greater London, n=11
96 days27 days

Half of these awards were announced within 96 days of the bid deadline.

How often single-bid or direct?
i

How often work is awarded with no recorded rival.

Direct awards and tenders where every published lot count shows one bid.

Both shares are minimums: some awards have no bid count.

Thin markets produce this too; it is not proof of a tailored specification.

Last 36 months.

Buyer: at least 91 of 206 procurements with awards had no recorded rival · market: CPV 3812 · UK-wide, n=26
44%73%

Direct awards or one recorded bid are common here. Check the route before spending time on a bid.

How many bids did past lots attract?

i

How many bids past lots received.

Each colour is a bid-count range. Only competed lots with a published count are included.

Past bids do not predict this tender.

Last 36 months.

How did awards compare with estimates?

i

Where winning prices landed against estimates.

Past prices are a guide, not a bid price.

How many bids this lot may attract.

The forecast uses similar past competitions. The bar shows either that forecast or past bid counts; the line below says which.

The forecast uses similar awards and the buyer’s estimate. The band covers the middle half of likely prices.

No comparable awards for this lot yet.

A statistical guide from past awards, not a price to bid.

—Estimate not published
The buyer published no estimate for this lot, so there is nothing to forecast against. A price prediction here would be a number about a number we do not have.

Candidate suppliers for this notice have not been worked out yet, so this is not a verdict that nobody fits.

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.
