How often should I top up my prepayment meter?

How often you top-up will depend on how much energy you use, and this will vary based on things like the time of year and how many people are using energy in the house. 

We advise that you check your credit regularly, and make sure you top-up accordingly, to avoid running out. Even if you’re away from home for an extended period, there needs to be enough credit on the meter to cover daily standing charges and any debt repayments.

We’ll also send you an annual statement, so you can see:

  • Your energy usage over the last 12 months
  • The payments you’ve made

What happens if I lose my prepayment card/key, or it stops working?

Please take good care of your top-up cards/key, as there’s a charge of £5 to cover the cost of replacing them. If you do need a new one, please call us on 0330 094 5802.

I’ll be away from home – do I need to add credit to my meter before I go?

If you’re going away, you still need to have credit on your meter. 

There must be enough to cover:

  • Daily standing charges
  • Any debt being collected by your meter
  • Any energy used while you’re away


If you don't keep your meter topped up with credit, you may go off supply while you're away. You’ll need to re-pay any outstanding amount plus £1 to get back on supply.

Emergency credit

All our prepayment meters come with 'emergency credit' built in. As the name suggests, it's for emergencies only - if you can't top up before your meter runs out of credit. 

You can activate it directly from your meter. The amount of emergency credit you use will need to be paid back next time you top up, plus an additional £1 to get back on supply.
