You have answered your own question. It is because they are powered all the time. If you are worried about it, fit an approved bathroom switch - pull cord?

Isn't the power to these things usually switched by a switch that's activated when a plug is inserted into the socket? This is a deliberate measure to avoid them humming, and a reason why you shouldn't leave shavers & toothbrush chargers plugged into them permanently.
