Presumably, 300,000 CO2 monitors is in the right range for one per classroom? Is ten classrooms per school a reasonable average?

It would make more sense to me to send 7-8k of them to say London schools than 20k to country schools.
Seems a bit tough to ever make them practical without central AC though, which is not common (nor any AC) in the UK.
I think it's the deep malaise of UK politics that they just hate spending money on anything, even if it will save far more money in the future. It's why the UK has the GDP-per-capita of Japan, but mostly looks like Serbia.
That sounds low: a secondary school with no sixth-form will have students in 5 different year groups, and will typically have more than two classes per year group.

Headcount 8,911,853 Number of schools 24,413 Average class size 26.6
So 335000 classes
that's just England, which is 83% of uk, so 402000 classes total
That's 335,032 classes, and thus at least 335k classrooms (add extra ones for specialist classrooms)
However that number includes private schools. Remove those and you're looking at 8.3 million, with a larger class size, so potentially just 277k classes assuming 30 people per room (plus specialist classrooms like IT, Art, D+T, PE, etc)
