It varies depending on the time of year, and what you use your energy for. 

Once you’ve had your prepayment meter for a while, you’ll have a better understanding of how much credit you need and when. You’ll probably need to top up more in winter and less in summer. 

We’ll also let you know how much energy you’ve used in your annual statement. You can see the payments you’ve made over the year there too.

Remember, if you don't use as much energy over the summer (mainly gas), a daily standing charge and/or a debt recovery rate will be applied to your meter. This means you may still need to top up even if you aren't using as much.
