Hi Sameer, Is it just lighting or sockets as well? It will have been done like that as prob the previous person didn't want damage to decoration. If you want this conduit removing the cables would need sinking into the walls and plastered over. He would also need to sink the back box into the wall. Cost would depend on whether you want the whole job doing or you get the electrical work done and you plaster yourself. Without seeing the job i think you would be looking at couple of days for an electrician and a day for the plasterer so prob looking at 600/700 Hope this helps Russ
