Hello.
I'm wanting to replace a single socket with a double socket, a fairly simply process and one I've done a few times on solid walls.
After turning the ring main off, and measuring it is as such, I removed the face plate.
Disconnected the wires and proceded to remove the metal backbox... which simply fell out. No screws into the wall.
After taking it out and clearing the rubble here is what I've got (I've reattached the faceplate for the time being)
The original 25mm metalbox didn't appear to actually be held in by anything substanial.
Behind the socket is polystyrene sheeting, which I am assuming is some sort of insulation (This is an exterior wall)
So my questions are: Is a metal backbox still the right thing to use, and do I need to 'fill in' the hole somehow?
Thank you in advance.
