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 26 named sources that could be read published a usable figure; 24 published none and are recorded as not published, never filled in; 0 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; 16 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 supplier: whether it covers SCHOOL holidays or only public holidays, which UK nations and which granularity (national, local authority, school), the formats served (JSON, iCal, CSV), the licence, the free tier and the published price, and whether the data is derived from the authorities' own pages or resold.
The figure across the rows is the coverage-versus-price frontier and, more pointedly, the COUNT of suppliers that publish UK term dates at local-authority granularity at all - which the reading puts in single figures, with the UK-facing school-holiday sites publishing no API and the priced APIs publishing no school data below national level.
Repriced-since on every pass.
16 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
