Hi Bianca . Yes , you need electrician before do plastering . Electrician should install cables , make holes for sockets and etc . If you do electrics after plastering your plaster walls and ceilings will be cutted to make way for cables or holes for sockets . After that will be fill up by plaster or filler . It will be double job and double cost . regards Bogdan Banasiewicz easy find on web
