    Is the condensation on the room side of the glass or inside the double glazing unit between the glass sheets?

    Yeah, that is a ventilation issue.

    Open up the windows for 20 minutes or open the trickle vents for the day otherwise if you have wall vents they are most likely louvered closed or covered over.

    the windows are just a cold surface and condensation is going to form unless the rooms passive ventilation is dealing with the moisture in the room. (or if you have good windows properly installed:()

    if your not happy with PUT's solution, I'd get a RH sensor and get a measure of the moisture in the room over time

    sometimes the upstairs rooms have moisture migrating from cooking,gas fire, showering, clothes drying and of course you guys sleeping...

    you have MEV's in kitchen, utility, bathrooms/en-suites?
