Soldato
Ahh damm ok sounds like they couldn't be bothered putting some work in...So it's a terraced house that is a room with a bay window, then the front door/hall, then to the right of that is a second smaller room a few metres back from the front of the house. Two guys came to install it and I spoke to the first one and he said it couldn't go into the smaller room as there was a radiator in the way on the inside a drain pipe on the outside so there was no room to drill. There is a 20cm-ish gap between the top of the radiator and window so I suggested drilling it there but he said the radiator would melt the wires. I never use that radiator so was happy for it to go half way up the wall even though it would look a bit weird.
Then the second guy who was doing the drilling told me that the cable coming from the telephone pole can't go round corners (since this bit is a few metres back from the front of the house) which seemed a bit ridiculous as the final installation definitely does a few 90 degree turns. In the end I gave up and let me stick it under the bay window.
When I eventually get mine done, I'll ask them to run it on the side of my house to go underneath my stairs as I plan to install a 6u network rack there with the Internet access point from community fibre and all my other network stuff
