Your guide to pay-as-you-go electricity

Pay-as-you-go electricity is a prepayment option where you buy credit and top up your electricity meter using a 20-digit top-up code.

You can buy pay-as-you-go top ups in the following ways.

  • At your local shops that are PayPoint outlets.
  • Post Offices.
  • Over the phone. 
  • Online or using our free smartphone app 24 hours a day, seven days a week.
