Want to put a tv aerial socket & phone socket in bedroom as planning to use as study. Thought it would be pretty straightforward & just a case of cabling going behind the internal bedroom wall however the installation man that came round was reluctant to do this & says it would be very difficult to feed the cabling behind the walls as this is usually done when the house is being built & he might find obstructions behind the wall. We have sky downstairs so he suggests taking it from livingroom, running cable outside along the outer wall and then into bedroom. For the phone cable we have a phone point in another upstairs bedroom & he suggests taking it from the other bedroom, then running a cable along outside of house to the relevant bedroom. Not keen on having holes knocked through to outside wall so wondering if this sounds like best option or whether he is waffling. (His other suggestion was to have cabling come down from loft through bedroom ceiling then down wall to tv but I don't like the thought of having a wire dangling from ceiling). He also says he doesn't like the sockets that you put on the wall for tv aerials & would be more inclined to put one of those little plastic round covers over the hole. Again I thought a socket would be neater - any ideas? Thought this would be simple!!
