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).
3 of the 58 named sources that could be read published a usable figure; 55 published none and are recorded as not published, never filled in; 3 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; 68 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 generator service visit across every UK service company that publishes one, cut by kVA band, by service level (minor, major, load bank test), by visits per year and by what the fee includes (labour only, consumables, parts, out-of-hours cover); beside it the SHARE of UK generator service companies that publish any price at all, which is the figure nobody computes and which this harvest already measured at under a tenth of the companies read - 5 of 58 own-site pages carried a price near a pricing term, and one of those five is a full price table by kVA band; repriced-since the previous read
68 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
