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).
7 of the 42 named sources that could be read published a usable figure; 35 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 in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 131 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 price per assessment type (walk-through audit, targeted audit, investment-grade audit, ESOS assessment, non-domestic EPC by level and floor-area band, DEC, TM44, ISO 50001) across every UK provider that publishes one; the share that publish a price at all versus quote-only; price per square metre implied by each floor-area band; and repriced-since between reads.
Nobody publishes the spread, because each firm publishes only its own band table
131 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
