UK Parliament: written statement on the BSL50 %

2 of the 18 named sources read in full publish a figure; 16 publish none, read 28 October 2026.

Every figure, with its source

One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

The sentence each figure was read from (2)
  • UK Parliament: written statement on the BSL, read 2026-10-28: A discounted rate of 50% of the standard levy rate has been set for works on previously developed (sometimes known as ‘brownfield’) land, to reflect the higher cost of building on this type of land.
  • East Hampshire: BSL guidance, read 2026-10-28: Developers who disagree with a levy charge or refund decision can request a review within 28 days.

Read in full, publishes no figure

16 named sources were read in full on the dates shown and print no usable figure. They are counted, never filled in.

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 18 named sources that could be read published a usable figure; 16 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 % (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 100 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): a decision table: liable person, trigger (building control application or initial notice on or after 1 October 2026), the exemptions with their thresholds, the PDL discount test, payment and review deadlines, each line cited to the regulation that sets it

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