Changing a Light switch !

Hi All,

I'm starting to repaint / reno the PROP. As I do each room, I want to change the light switches and the door handles.

If its a 3 gang switch, i will change it to exactly the same, just nice and new / trendy.

I know i can't do this by law but I'm sure people do it everyday...............

So, I'm not sure if anybody will answer the question, to do it or not?
