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 10 named sources that could be read published a usable figure; 8 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; 34 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 nation for the permission rule, quoted from the Order and the Regulations with the class named, beside a row per LOCAL AUTHORITY for the building control fee for a garage conversion, read from each council's own published fee schedule - the two councils read here charge £739 and £720 for the same job, and no one publishes that spread across all 300-odd authorities, which is the dataset.
34 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
