The first thing to ask oneself is why is the powerpoint surface mounted and not cut in the wall. It could be that it was done not by an electrician and the person was not confident to cut the plasterboard. It could be that the wiring is also surface mounted to the wall. It could be that at that point the wall has many studs and the powerpoint can not be cut in.
However, a powerpoint can be moved 99% of the time, so it is a simple job for the sparky.
