Im moving house soon and likely will need a third box. the first box will be at virgin entry point to the front of house (lounge) but the other two will be potentially at the back of the house (second reception room) and a bedroom on first floor at back of house. the house is a stone terrace so there is no option to run cables around side of house.
so how would the cables be wired to get to the back rooms? what are the options?
You can go under the floor of you have a huge crawl space.
Through the house.
You can assist the technician by the tech running it up the wall through the loft and back down the other side. Officially techs are not allowed in loft if not floored so you possibly may need to assist that part
