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.

Read in full, publishes no figure

48 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).

5 of the 53 named sources that could be read published a usable figure; 48 published none and are recorded as not published, never filled in; 2 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; 166 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 per door for an inspection, a survey, a repair, a supply-and-fit and a flat entrance door replacement, per region and per job size, beside the visit minimum and the door count at which the per-door rate steps down; the same for the qualification (FDIS diploma and certified inspector stages, City & Guilds courses, association fees) and for the inspection software a contractor prices the job with.

The derived figures: the volume curve that nobody draws (what twenty doors costs against two hundred, read across every company that publishes a band), the London premium measured rather than asserted, and the share of the market that publishes a price at all.

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