Looking through TLC-Direct UK's range of shaver sockets, I've noticed they've added something to it.

A note that says only dual voltage 120/240 volt shaver sockets can be used in washrooms and bathrooms.

I had never noticed that before. Is this something new and why did they change it? I thought the 240 volt only shaver sockets also came with an isolation transformer?

Anyway, there is still one shaver socket sold that is 240 volt only, with the warning, obviously.

So....why is this single voltage device still being sold? Is it for replacement use or do people install these in other places besides the bath?
