Can someone link me to the data that shows where exactly transmission is happening (schools, pubs etc)

Exactly that! Talking to a friend and we have differing opinions on where the worst spreading is taking place. I don’t seem to be entering the right thing into google to find that data. All I’m finding is info one cases in each country.

However it is worth noting that the info on where cases are occurring is only in institutions (so won’t include transmission through meeting inside private houses), and an outbreak is classed as two or more cases in the same institution, so doesn’t differentiate between two unrelated cases in the same school or workplace, and widespread transmission occurring within the institutions
