Demolition Disposal Tax and Levy Rates

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).

5 of the 10 named sources that could be read published a usable figure; 5 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 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 11 figures, never sentences; 50 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 UK nation per rate per tax year, quoted verbatim from that nation's own tax authority with its effective date, and the derived figure a demolition buyer actually wants: the tax component of a tonne of mixed demolition waste against a tonne of inert hardcore, the year-on-year change, and the four nations set side by side - which is the comparison no single authority publishes because each publishes only its own

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