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).
18 of the 58 named sources that could be read published a usable figure; 40 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 for each breakdown it prices, in GBP (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 26 figures, never sentences; 526 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, lowest and highest advertised installed price per structure type (lean-to, Victorian, Edwardian, gable, P-shape, orangery, garden room) and per size band (3x3, 4x3, 5x3, 5x4 m), normalised to a price per square metre so a conservatory, an orangery and a garden room can be compared on one axis - the comparison no supplier publishes because each publishes only its own; beside it the count and share of suppliers publishing a price at all versus quote-only, what a published price includes (base, electrics, VAT, installation), the supply-only versus fully-fitted spread, and repriced-since the previous read
526 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
