I've been searching the web to no avail. Is it possible to get a 4 gang switched wall socket to replace a current 2 gang one? I've found a triple but thought that I may as well go to 4 if they are available. I want to use a couple of Homeplugs but am aware that they don't recommend using them with trailing sockets. If I dedicate 1 socket to the plug then that means having everything else hanging off the one remaining socket!
