Why is pay as you go more expensive?
Cost of
*Meter itself (more expensive)
*The keys for it
*Additional staffing costs for call center and back office teams
*Engineer training and installation/removal costs of the meter
*Software costs to support the key meter systems.
*Legal and admin costs (installing on warrant etc)
The admin costs alone represent a large cost, the time taken to deal with one customer fully and to get a prepayment meter installed is silly, then to manage that customer who will most likely have further payment issues is again costly.
