A bit of a long shot i know but is it possible to move a flush fit twin wall socket down about 3 inches without having to chase a new mounting box? There are 2 sockets located above the kitchen cupboards supplying a fitted fridge and lighting but I want to fit some coving around the kitchen and the sockets are too close to the ceiling for the coving to fit in between. I can cut a slot in the coving above each outlet but that won't look ver clean! Are there any options other than to remove the sockets, take out the mounting boxes and chase further down to relocate?
