//If you are taking a BT Infinity package, then we won't charge you for installing or reconnecting your line. If you are taking a BT Broadband package, then we will charge you £30 for installing a new line. These charges apply whether or not you add BT TV to your package.
If you are ordering a BT Phone package, you may have to pay a connection charge but we'll let you know when you order. There is usually a £70 fee for activating an existing line that is provided by BT or another provider, and a £140 fee for installing a new line.//
