Published values on the notices that demand it — a floor, not a total.
The demand curve
Notices demanding it per 10,000 published, by year — rate-normalised so corpus growth never masquerades as demand. Complete years only.
The pale bars are 2025 onward. The Procurement Act went live on 24 February 2025 and changed how notices are written, so the step across that date is partly a change in convention and not only a change in demand. We have not measured how much of it is which, so please do not read this as a trend.
The receipts
Notices that demand it, and the sentence each demand was found in. Nothing is counted here without one.

Get set up free →Method: Every count here is a floor. We match the text of the notice, and a notice description is a summary — most tender packs demand things it never mentions.“Said must” counts only explicit obligation language in the matched sentence itself; anything ambiguous is counted as a mention, never as mandatory. Trend compares rates per 10,000 notices per complete calendar year.
