How UK Atomic Energy Authority buys Instruments for measuring quantities (CPV 3834) — and who usually turns up

UK Atomic Energy Authority’s own published record, next to the South East England market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Instruments for measuring quantities (CPV 3834) →

How the contest usually goes

Left: this authority. Right: the market where the work is delivered. Bids and award-vs-estimate pairs are per lot, from contested contracts only — direct awards (including PA 2023 transparency notices) report one bid by definition and are left out. On Procurement Act 2023 notices the count is the tenders assessed at the final stage, not every submission received; pairs compare like with like (VAT-exclusive, or VAT-inclusive on both sides). Empty means nothing was published, not filled in from elsewhere.

Where this tender’s estimate would land if the usual pattern repeats.

We apply the buyer’s usual movement between estimate and award (or the region’s) to the estimate on this notice.

Based on this buyer’s own usual movement over 6 lots (division 38), applied to the £1,000,000 estimate on this notice.

A benchmark, not a price to bid.

The middle award in UK Atomic Energy Authority (division 38, n=6 pairs) lands 7% below: on this notice’s £1,000,000 that is about £934,000. Context for a bid, not a recommended price.

Matched by the nightly worker on class wins, buyer history, delivery geography, scale and notice text; relevance is a 0–100% heuristic score, not a probability of bidding. “Their award vs estimate” is that supplier’s middle value on its own comparable single-supplier wins, CPV 3834 first. Nobody here is known to be bidding.

Coverage and what to read with care
  • Each tile explains itself. The on a figure says what it is, how it is counted and which scope this notice’s own record came from (class, division, all categories, or the authority’s 24-month row). The two columns are never blended and nothing is filled from a UK-wide figure; an empty tile means the source published nothing usable. Long form: Methodology.
  • Coverage. Roughly 40 % of notices publish a bid count; about half publish an ITL1 delivery location, so the market column reads the authority’s registered region when the notice has none (labelled). About 30 % of award-vs-estimate pairs are exact matches — the buyer published the award at the estimate. n is on every figure; a thin sample is muted, never hidden.
  • “Match” and “relevance” are model scores from the nightly matcher, not published facts. Find a Tender does not publish who is bidding. Never shown: contact details, payment behaviour, or a recommended price.
