You may be given a prepayment meter if you have existing debt with your energy company and they want you to pay back the debt. You may also be given one if you fail a credit check or don’t have a good enough credit record to get an ordinary meter.
Electricity prepayment meters are usually installed inside the property, gas meters can be found inside or outside the property.
A prepayment meter will have a place to insert a key or card which tops up the meter with credit.
You can top up at the Post Office or any local shop or garage which displays the Payzone or PayPoint logo :
