It's free up to a certain cost. There is a "price per home" to connect you from where ever the cable is in the street.
For example if there is literally no way to get a cable to your property without digging up 5m of concrete and reinstating it, they will not install it.
Sorry this is no longer he best image but I hope it will suffice. I've lost the screw that goes in here on the passenger side of a 18.tsi (2017)
Wonder if you can identify it and give me a price
