Glazier call out charge: UK Glazier Price Index

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).

12 of the 42 named sources that could be read published a usable figure; 30 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 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 18 figures, never sentences; 238 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): Nobody publishes a Great Britain glazier price series, and the number the buyer wants at eleven at night - is £180 for boarding up one window normal where I live - cannot be read off any one firm's page.

Ours is the aggregation: the median, minimum and maximum published price for each job the trade actually quotes as a unit (emergency callout per window, boarding-up per window, a replaced single pane, a replaced sealed unit by size band, an hour of labour, a day rate), computed across every glazier that publishes one, per UK region; the COUNT and SHARE of glaziers publishing any figure at all against those that quote only on inspection, which is the market's most useful number and is published nowhere; the CALL-OUT FEE as its own row in both directions, because the sector's competitive claim is now 'no call-out charge' and the index can say how many firms actually make it rather than repeating it; the out-of-hours multiplier measured as the same firm's daytime and night figures rather than asserted; the near-identical headline fee across firms (£73, £75, £75, £75, £75 for the same emergency window on five different sites read on one day) recorded as an anchoring finding rather than smoothed into an average; and repriced-since the previous read.

Every figure is quoted verbatim from the glazier's own page with the retrieval date and the region it was published for; a lead marketplace's figure never enters the index, and a firm that publishes nothing is recorded not-published.

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