How do I top-up the credit on my prepayment meter?

Topping up credit on your prepayment meter

Once you've activated your new key or card, you can buy credit at a local outlet and add the credit to your meter.

As an npower prepayment customer, you can top up at PayPoint, Payzone and Post Office outlets. There's a list of your nearest outlets in the letter we sent you with your key or card. You can also look online to find your nearest outlet:

To top up your credit, take your card/key to an outlet.

  • The credit you buy will be added to your key or card.
  • You can buy any amount of credit in whole pounds up to a maximum of £49 per transaction.
  • You can have up to £249 credit on your gas meter, and £255 credit on your electricity meter.

Always buy credit for your meter using your own npower programmed payment key or card to make sure the money is credited to your account. If you use a key or card from a previous supplier, the money you pay may not be credited to your npower account. You could be charged the wrong rates and your payments may go to the wrong supplier. Only top up at an authorised outlet and never buy credit from anyone visiting your home.

Transferring credit to your meter

Gas meters

Simply insert your payment card into the slot in the meter. Press the Red Button A to transfer your credit to your meter.

Electricity meters

Insert your payment key into your meter. The screen will briefly show the amount of credit on your key. To ensure your credit is transferred onto your meter successfully, we recommend you leave the key inserted for at least 5 seconds.
