If possible I would consider drilling your own hole in advance. I let Sky man drill hole for the cables and that was a mistake. These guys are in a hurry so they put the drill on hammer mode and just push hard until a large blow out exit side. Mine was size of my palm so I had to use filler to repair this and paint it.
Before the Virgin man came round I purchased a 6mm long drill bit from ebay and slowly took my time to make a tidy hole. By the time the drill bit went through wall the hole must have been 10mm enough for the cable..an no damage at exit side 😁
