Renovating an old house which needs new electrics. Our "sparky" needs a drawn up electrics plan when he starts on Monday. I've worked out where I want lights/sockets etc. However, where can I go for advice on computer points/bt points/possible sound system wiring... I have no idea what I need - sonas and cat 5 have been mentioned to me. Someone said I should put a bt point wherever I put a tv point? Any good websites for this info anyone can recommend? Apparently the broadband signal isn't strong in this village. Overwhelmed - any help gratefully received. Thanks
