Your best solution would be to get the free install from the Post Office, and once your month is up sign up for Sky Unlimited, (with or without TV). They will be able to take over the PO line, but you may have to pay £15.
"If you cancel Post Office HomePhone® within six months of any New Line Provision, we may charge you a cancellation fee to cover our reasonable costs. That cancellation fee is set out in the Price List."
From Price List:
"New Line Provision Cancellation Charge - HomePhone
"If you cancel Post Office HomePhone within six months of any New Line Provision, we may charge you a cancellation fee of £15 tocover our reasonable costs."
If you're lucky, it won't count as a cancellation. You don't say anything to them, just let the Sky signup trigger it from that end.
