If your talking Virgin Media for instance, and you live in a "new build area" cable was never originally installed ungrounded years ago by them. Forget it, I used to work for VM as a cable engineer doing full installs. If you don't already have cable there ready for connecting into your home from outside, your knackered.
If they are expanding, doing more areas now I have no idea? But you can check your "post code" on their website to see if VM is available in your area.
