Who is a Prepayment Meter suitable for?
Firstly is Landlords who rent their property out. Many landlords choose to install a prepayment meter as it means their tenants are responsible for paying for their electricity as they go and won't leave the landlord with an unexpected bill to pay if they move out. Also it reduces any headache of changing the names registered with the energy company each time a tenant moves out and a new tenant moves in.
Secondly, a prepayment meter may be a good idea for those that have struggled to keep up with bill payments in the past. If a customer has fallen into debt with their energy company, the energy company may install a prepayment meter to help the customer control their budget.
