How Karbon Homes buys Roof works and other special trade construction works (CPV 4526) — and who usually turns up

Karbon Homes’s own published record, next to the Yorkshire and the Humber market for the same work. Frameworks and DPS are kept out: they attract a different number of bids. Whole-market view: Roof works and other special trade construction works (CPV 4526) →

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.

This notice gives one total for several lots, so we show the percentage but do not turn it into pounds.

A benchmark, not a price to bid.

The middle award in Karbon Homes (all categories, n=7 pairs) lands at estimate. Applied to each lot’s own published value in the lot table below — the notice total (£16,958,400) is an envelope for 10 lots and is not converted.
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.
