Just a little tip if you are wanting a landline only - there is a deal called home phone saver 2019 - its not actively advertised on their website but its £21.99 fixed for line rental and anytime calls for upto an hour until 2019, this also includes BT Call Protect, BT Privacy at Home and BT Privacy at Home - Caller Display.
I already had virgin installed a couple of months back and have a rock solid 221 Mbit connection, and was still in contract for infinity till April. The price hike has allowed me to cancel infinity early without a charge.
The wife wants a landline and i want to keep it incase virgin goes belly up and i can be up and running with infinity as a backup within a couple of weeks if needs be.
