Every figure, with its source

One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

The sentence each figure was read from (20)

Read in full, publishes no figure

58 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).

19 of the 77 named sources that could be read published a usable figure; 58 published none and are recorded as not published, never filled in; 4 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 20 figures, never sentences; 257 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, minimum and maximum published fee per firm, normalised three ways nobody else normalises: VAT in or out (the market quotes both and the difference is a fifth of the price), survey type (snapshot verbal, damp-only report, combined damp and timber, pre-purchase lender report), and property size band.

Against that sits the count and share of firms that publish a fee at all versus quote-only, and - the row that matters most to the buyer - the share whose survey is FREE because the firm sells the remedial work, recorded as a zero with the model named rather than averaged in.

Then the regional spread: London and Bristol against the North West and Yorkshire, and the same national brand's price in different cities, which the reads already show moving from £190 to £650 for the same nominal product.

Repriced-since each monthly read.

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