How this buyer will score bids.
The evaluation criteria and weights exactly as published on the notice, grouped by family (price, quality, social value and so on).
Published award criteria (2)
- Quality: Please see documents
- Price: Please see documents
No conditions of participation were published on the notice; check the tender documents.
- Price carries 40 of 100 points: a 10% discount moves about 4 points. The method statement decides this lot, not the discount.
- Turnover usually expected at this size: about £800,000 (twice the annual value).
Price arithmetic assumes straight proportional scoring; the tender pack may use another formula. Turnover is an indicative market norm (≈2× annual value), not a published condition.
Competition analysis · published record, not a forecast of who will bid
How UK Atomic Energy Authority buys Pumps and compressors (CPV 4212), and who usually turns up
UK Atomic Energy Authority’s own published record, next to the published market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Pumps and compressors (CPV 4212) →
How the contest usually goes
Winner shares use published awards; bid and price charts use contested lots.
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.
Small firms have won here. Neither number says whether you qualify; it describes who has been winning.
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 registered in South East England (authority’s region).
A local branch does not count if the registered address is elsewhere.
Most of this buyer’s recorded winners are registered outside South East England.
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.
Half of these awards were announced within 17 days of the bid deadline.
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.
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.

How did awards compare with estimates?
i
Where winning prices landed against estimates.
Each colour shows awards below, close to or above the published estimate, one lot at a time.
Past prices are a guide, not a bid price.

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 match score 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.
