I have recently had some new tiles put up in the kitchen by a builder,I had eight double sockets in the kitchen and he asked did I really need them all.I said not really and he has now removed two and put the tiles over the top.My friend has come over today and I had said what he has done and he seemed surprised that there was no blanking plate.Im unsure of what to do next,could anyone shed any light on this one for me.Many thanks
