Every figure, with its source

One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

The sentence each figure was read from (6)

Read in full, publishes no figure

30 named sources were read in full on the dates shown and print no usable figure. They are counted, never filled in.

Methodology

Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).

6 of the 36 named sources that could be read published a usable figure; 30 published none and are recorded as not published, never filled in; 4 could not be read (blocked, dead or unreachable) and count nowhere.

The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 81 candidate sentence(s) were refused by a reviewer with the reason recorded.

The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the median, minimum and maximum PUBLISHED price for a legionella risk assessment across every GB provider that publishes one, cut by property type (single let, small commercial, care home, hotel, healthcare estate) and by outlet or asset count where the provider states it; the share of providers publishing a price at all versus quote-only; the London premium measured as the gap between providers publishing a London price and the same providers' national price; the share of publishing providers that appear on the Legionella Control Association register; the per-sample laboratory price beside it; and repriced-since the previous read.

Nobody publishes any of this: every incumbent page is one firm's own price or a journalistic range.

81 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
