## 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). 4 of the 21 named sources that could be read published a usable figure; 17 published none and are recorded as not published, never filled in; 1 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; 36 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): each surveyor's published price normalised to ex VAT and banded by PAS 128 survey type and quality level (QL-D desktop, QL-C reconnaissance, QL-B detection, QL-A verification per trial hole), by site area and by day rate; the median and range per band; the share of surveyors that publish any price
