Ethernet cable through house

[JonLow]

I'm having my house rewired and want to get ethernet cable run throughout at the same time. The electrician is fine with running the cables etc, but not so knowledgeable about the network side. My plan is to have him run cable from where the router will live up to the loft, have a network switch in the loft and from there a cable each down to the various network points. Is that a good/right approach? Am I missing anything?

Thanks for any help

Ok, so maybe think about putting the switch in my office (on the first floor). But the general approach is right? Also, I've read a lot about getting one more cable that needed run to each location, in case of issues in the future. e.g. I want one port in the spare room, but having two cables run to that location. Is that necessary or a good idea?

Thanks for the replies
