Subsidence Report Fee Index

Last updated 2026-10-27

Every provider below was read on its own page through our fetch box, and the row says what that page published on the day we read it. 17 of 94 publish a figure; the rest are listed too, because how many will not quote a number is the most useful thing about this market. Nothing here is a quote for your job: it is what other people advertise.

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). 17 of the 94 named sources that could be read published a usable figure; 79 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 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 19 figures, never sentences; 905 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 provider per PRODUCT - because 'subsidence survey' is six priced things and the buyer does not yet know which he needs - carrying the published price or range, whether it is a from-price, a banded ladder or a per-visit rate, whether VAT is stated, and the region. Across those rows the figures nobody publishes: the median, minimum and maximum published price per product and per region; the full cost of the whole investigation path a real case runs (engineer's report, then drains, then trees, then monitoring, then trial pits) against the single number the buyer searched for; the share of providers publishing a price at all, by product - which the harvest shows is far higher for drainage and arboriculture than for structural engineering; whether VAT is included, which moves a quoted £275 to £330; and repriced-since the previous read
