I thought you were talking about the cost of the static IP address. Many ISPs charge a monthly fee, unless it is supplied as standard with the product. The Plusnet one-off charge is quite unusual.
The indispensable man or woman passes from the scene, and what happens next is more or less the same thing as was happening before.
