## 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). 2 of the 0 named sources that could be read published a usable figure; 0 published none and are recorded as not published, never filled in; 14 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 surveying (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 10 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): one row per body per designation: what the designation requires, what a listed firm must hold (professional indemnity, complaints handling), how many are listed, and the regional distribution. Across the bodies the figure nobody publishes: how many firms in a given region hold each designation, the overlap between them (a subsidence instruction routinely needs a RICS firm AND a chartered structural engineer AND an Arboricultural Association consultant), and how many of the firms actually selling subsidence surveys on the open web appear on any register at all - which is the real consumer question behind 'is my surveyor registered'
