Not sure of cost. Probably depends on where you are. But I would ring up some sparkys and ask for their price per switch. I wouldn't pay by the hour. They will probably charge a call out fee as well. Ring someone who says 'no job too small'. I hesitate in saying that it won't be too expensive because we all have different views on what is expensive but it shouldn't be a huge job. Oh and get three quotes if you are concerned about price.

Hi Jane, Your electrician will advise you of anything you need to be aware of. I'm sure a phone call to them could answer your questions.

Yeah they can open! Only thing is the two doors opposite each other, one is leading into the bedroom from the hallway and main part of the house and the other goes into a private lounge room. So it’s kind of a walk way. Unfortunately the second option isn’t possible. I live with my grandparents and have brick walls so they won’t be too keen on me having that done (they’re fussy old people) might just have to go with the first option and see how it works for me! Appreciate the suggestions!

If you are happy with the walls as they are , its a huge cost and effort to just hide some power points . To a small degree , it will also depend what you want to run . Really power hungry appliances ( 2000 watt heaters etc ) may need new wiring , rather than just hooking into the existing wiring . But like bigreader , I'd look at coduit , extension leads ( if lower power use ) and even multi-boxes -- I have used individually switched brushed stainless 4 way ones ( about $80 instead of $10 beige unswitched ones ) and even mounted them to the wall -- they look quite classy and purposeful . And if all else fails , using furniture to hide leads is a good idea .
