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).
2 of the 12 named sources that could be read published a usable figure; 10 published none and are recorded as not published, never filled in; 2 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 3 figures, never sentences; 5 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): one row per register and scheme - the statutory gas register, the seven WaterSafe approved-contractor schemes, the trade bodies and the government-endorsed quality scheme - with the instrument that compels it where one does, the entry requirement, the published annual fee, the insurance floor, and what the scheme's own rules permit a member to display.
A plumber's site earns its credibility from these rows, and the fee-and-requirement comparison across them is published nowhere.
5 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
