Commercial EV charger cost UK: Commercial Install Cost 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).

6 of the 21 named sources that could be read published a usable figure; 15 published none and are recorded as not published, never filled in; 1 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; 56 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 installer per charger class (7-22kW AC, 50kW+ DC, ultra-rapid) carrying that firm's own published from-price and the cost lines it names - hardware, groundworks, cabling run, DNO application, back-office - and across the rows the median and range of published per-socket prices by class, the share of firms that publish any price at all versus quote-only, which cost line each blames for the spread, and repriced-since; nobody publishes that distribution, and it is the only honest answer to a question whose real answer today is 'between £1,500 and £15,000'

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