Construction safety companies: Safety Accreditation Register
The Safety Accreditation Register carries 2 published figures read from 4 sources' own pages, from 8,000 to 50,000 members, read 25 September 2026.
DailyLogDesk sells its own paid plan in this category (our pricing). It is not counted here: every figure in this index is another provider's own published price, read from its own page.
4 of the 16 named sources read in full publish a figure; 12 publish none, read 25 September 2026.
Every figure, with its source
One row per source: the figure the source's own page publishes, the page, and the day it was read. A figure that is not on a page we read is not on this one.

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 16 named sources that could be read published a usable figure; 12 published none and are recorded as not published, never filled in; 0 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 members (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 11 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 scheme: who runs it, what it assesses, whether SSIP recognises it, the certificate a principal contractor will accept, and the count of accredited businesses each scheme itself publishes.
The derived figure is the RECOGNITION MAP - which schemes are mutually recognised and which certificate satisfies which buyer - beside the count of accredited businesses per scheme and the overlap between them, which no single scheme publishes because each counts only its own members.
11 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
