Do i need a licensed asbestos contractor (2 figures)

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 9 named sources that could be read published a usable figure; 7 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 day (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 2 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 material x condition x work: the class the Control of Asbestos Regulations 2012 puts it in (licensed / notifiable non-licensed / non-licensed), the notification period and form, whether a four-stage clearance certificate by a UKAS-accredited analyst is required, the medical and record-keeping duties, and the Northern Ireland equivalent - each read from the regulation or the regulator's own page.

Joined to the price index this is the estate's own finding: the multiple the law itself puts on the bill, per material, which no cost guide derives and no HSE page prices.

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