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 27 named sources that could be read published a usable figure; 22 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 in GBP (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 110 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 publisher: the price to file a company tax return (per return, per client or per year), whether a free tier exists and what caps it, and for advisers the FEE MODEL - contingent percentage of the claim, fixed fee or hourly - with the published percentage where one exists. The figures are the spread across publishers, the share publishing at all (of 26 publisher pages read on 2026-09-11, half carried no number), and the contingent-fee band for an R&D claim, which the firms advertise unevenly and nobody collects; measured against HMRC's own register of recognised suppliers, so the denominator is the whole market rather than the firms that answer a search.", "embed": "
