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.

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.
