Help! needed re tv points, sockets, ethernet points

[Sparkysea]

Hi All
Am in process of house renovation and electrician wants plan of where I want the switches, sockets, etc.tomorrow! I am also requesting they put in tv points and ethernet points
Does anyone have any tips on what to consider please?
It will be 4 bed house when loft conversion is done and I wondered if there might be probs if I have a tv point and ethernet point in each room, e.g splitting tv signal and bt line .....
For the last 5 years I have watched tv on laptop in bed and am not sure what can be achieved nowadays..
Thanks for any advice

Thanks all very much for your guidance. Have posted an update on the Homes and gardens forum section. Thought I had better not duplicate!
