Joining us with a prepayment meter?

If you've just moved over, your new gas card will be with you soon. Don't worry about the electricity key, you can keep on using your current one.

Once you've received your new gas card you'll need to register it before you can top it up with any credit. Just pop it in your meter and leave it for two minutes or until it beeps, simple.

Top tip - make sure you use up your credit on your old card before using your new one.

If you do need a new electricity key don't worry, call us on 0808 501 5200.

If you have an outstanding debt, we'll continue taking this at the same rate you agreed with your previous supplier.

How to top up a prepayment meter.

It's easy to top up at a Payzone, PayPoint or Post Office outlet. You can find your nearest outlet on their respective websites.

Just hand them your key or card with the amount of money you want to top up. A minimum of £1 is needed (full pounds only).

Remember, keep topping up your meter during the summer. You might use less energy, but the standing charge is still debited each day from your meter during summer months. Keeping your meter topped up, helps you spread the cost throughout the year and makes you more prepared for winter.

Gone into your emergency credit?

Don't worry, for emergencies your meter will make £10 for electricity and £10 for gas available to you (known as your emergency credit). You'll need to pay this back when you next top up.

For gas, you can use the emergency credit if you've got less than £2 left. Pop your card into the meter and pressing the red button 'A'

For electricity, you can do this if you've got less than 50p left. Pop your key into the meter and then press the blue button.

Paying debt through your prepayment meter.

Your meter will collect any outstanding balance, if there is one, at the rate we've agreed with you. You'll need to top up enough to cover your weekly repayment amount, regular energy use and daily standing charge.

For gas prepayment meters:

Your meter will take money for this debt until the weekly repayment amount has been paid in full. It will take this amount from your first top up after a Wednesday morning each week, and every top up after that until your weekly amount is paid. Any money owed to the meter will be taken in full before you get any gas or electricity.

For gas, the top up will be allocated as shown in the example below
