 "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). 31 of the 56 named sources that could be read published a usable figure; 25 published none and are recorded as not published, never filled in; 6 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; 422 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): median, lower and upper quartile and range of the published CP12 price per appliance band (one appliance, two, three or more), with and without an annual boiler service, across every UK engineer and certificate firm that publishes one, normalised to a VAT-inclusive figure, by region; the price of each extra appliance; the share of firms that publish a price at all against quote-only, and the gap between national booking firms and local engineers; repriced since the previous read.",
