There are very strict regulations (Part P of the Building Regulations) stipulating what work you may and may not do to the mains electrical wiring system in your home. More details of Part P can be found in the regulations topic.
There are two golden rules:
1) Be certain you have turned the electricity off;
2) if you do not understand what you are doing do not do it.
All the tasks considered here are permitted by Part P as of July 2007 – however they may well be altered in the future. If you are in any doubt, ask the advice of a suitably qualified electrician.
