A prepay or "pay-as-you-go" meter allows you to buy your energy in advance, before you use it (just like a pay-as-you-go phone).
To access your gas and electricity, you'll top up your meter with credit that you've bought from a local shop, garage or Post Office. There's different ways to top up, but you'll usually use a card or a key to do this.
Because you pay for your energy as you use it, you won't get regular bills from us.
A prepaid gas or electricity meter can help you to budget for your energy use. You know how much energy you've got, how much you're using each day, and when it's running low.
