Flexibility and convenience all-in-one.

What is Smart Pay As You Go? 

Think of it as a prepayment smart meter. Smart Pay As You Go combines the flexibility of a pre-pay tariff with the convenience of a smart meter. You’ll get an in-home display which you can use to view and manage your energy usage in the comfort of your own home.

Gas, flash, sun, leaf and cloud hugging house.

The smarter way to top up your energy.

Smart Pay As You Go still allows you to pay for your energy as you use it, but with new ways to top up. You can top up using our app, online or in PayPoint, Payzone or Post Office stores. You also get alerts when your credit is running low.

And if you do run out of credit, we won't disconnect you on weekends, UK Bank Holidays or between 4pm and 10am Monday to Friday.
