Yes, he explained it to me in similar terms (not only are the sockets expected to be live at all times, there was, too, no switch available for this purpose, as no manufacturer would test and sell a switch for a type of operation which is not permitted by regulation). He further explained the importance of standard and as-expected behaviour of home electrical appliances. We finally managed to arrive at a legal, workable and overall sensible solution, but it was no easy feat. I wish I had the option to just put some switch-equipped sockets - of course, only where I want them, keeping the rest as it is. Coming to think of it, instead of a kitchen isle I wish I had built a British isle. See icon.
