How much is home insurance: Premium Benchmark Series

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 15 named sources that could be read published a usable figure; 9 published none and are recorded as not published, never filled in; 2 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 % (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 7 figures, never sentences; 211 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 series per market joining the official average premium to the published prices in the index: the ratio of a named insurer's advertised 'from' price to the authority's average for the same cover and place, per year, which is the number that says whether a headline price is a real discount or a teaser.

Nobody publishes that ratio because the two halves sit in different institutions - NAIC and the FCA publish the average, the insurer publishes the shelf price, and neither cites the other.

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