Get help with your prepayment meters.

Not sure where your nearest top-up point is or how to check your credit? Here's how you do it.
Frequently asked questions about prepayment meters.
I've moved from another energy supplier, will my prepayment card or key continue to work?
Both electricity and gas card or keys will continue to work while your account moves over. When your move is complete, we’ll send you a new gas card which you can start using straight away.
If you have an electricity prepayment meter we don’t need to send you a new key and you can carry on using your existing one.
If you haven't received your new gas card a couple of days after we've moved your account, please get in touch.
Where can I top up my prepay meter?
You can top up at any Payzone, PayPoint or Post Office outlet. You can find your closest outlet on their website.
What is my emergency credit?
For gas - Your prepayment meter has £10 emergency credit, available when you have less than £2 left on your meter.
For electricity - There's £10 emergency credit and you'll be able to activate this when you've got less than 50p left.
Just remember, you'll need to pay back your emergency credit the next time you top up.
How do I use my emergency credit?
For gas - If you want to use your emergency credit and you’ve got less than £2 left; put your card in the meter then press the red button ‘A’.
For electricity – if you want to use your emergency credit and you’ve got less than 50p left, put your key in the meter and press the blue button. Your meter may make a noise when your emergency credit is available to use.
Why do I need to top up every week?
It’s part of your agreement to top up your meter with credit every week even if you aren’t using energy. This is to ensure that your debt is repaid in line with your repayment agreement.
If you don’t keep up with the repayment schedule, the meter will take an amount each night from the available credit until the repayments are up to date.
If you don’t top up your meter, we’ll carry on taking a higher weekly debt repayment amount until you’ve caught up with your repayments.
If you’re struggling to pay, please tell us as soon as possible on 0808 501 5200 or email us at hi@eonnext.com. We’re here to help.
I use less energy in the summer, do I still need to top up?
In the summer months you must remember to keep topping up your meter. You might use less energy, but the standing charge is still debited each day from your meter during the summer months.
Keeping your meter topped up, helps you spread the cost throughout the year and makes you more prepared for winter.
How do prepayment meters work?
Prepayment meters are really easy to use. It's a bit like a pay as you go mobile, you just top up with credit to get your electricity and gas.
The top-ups work in different ways. For gas we'll send you a card and for electricity we'll send you a key. You can take these to any Payzone, PayPoint or Post Office outlets to top up.
What if I can't get to a shop?
Don't worry, for emergencies you can activate emergency credit on your meter - there's £10 for gas and £5 for electricity (being increased to £10 - we'll contact you when this is changing on your meter). Just remember, you'll need to pay this back when you next top up.
Can I switch from a prepayment meter to a credit meter?
Yes, as long as you're not paying back a debt through your meter and you pass a credit check, we can book an appointment with you within a reasonable time frame to swap your prepayment meter for a shiny new smart meter.
If you switch to a credit meter you'll pay for your energy monthly by Direct Debit or we'll send you a bill (which you’ll need to pay in 7 days).
If your circumstances mean that a prepayment meter is not safe or practical it's really important that you talk to us so we can help.
I'm moving home what should I do?
Moving home can be a really exciting time with lots to organise, but don't forget about your energy.
Just tell us as soon as you know your move date, as we don't want you to end up paying for someone else's energy. We'll ask you to take some meter readings, when you move, so we can close your account with us.
To get in touch about your move just email us at hi@eonnext.com or just give us a call on 0808 501 5200.
I've just moved into a house with a prepayment meter, what should I do?
Don't panic, all you need to do is contact us at hi@eonnext.com or give us a call on 0808 501 5200. If you don't you could end up paying the wrong rates as the previous occupier could have had a debt with us.

Check out our blog about the 5 things you need to know about your electricity and gas prepayment meters.

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:
Steps | With a debt | Without a debt |
|---|---|---|
Step 1 Value of top up (full pounds only). | £10 top up | £10 top up |
Step 2 Is there a weekly repayment rate? | £5 weekly repayment amount | £0 weekly repayment amount |
Step 3 Is there any Emergency Credit or Standing Charge owed?* | £2 emergency credit and standing charge | £2 emergency credit and standing charge |
Step 4 Any remaining credit will be allocated for gas | £3 credit for gas | £8 credit for gas |
*Press the red 'A' button to check the owed screen
For electricity prepayment meters.
Your debt repayments will be taken at regular intervals throughout the week.
Is there support available?
Yes, we can help you find the resources and advice you need if money is tight. Find out more about what support is available to help you pay your energy bills.
If you're worried or struggling to pay, please contact us so we can talk to you about this. We might be able to offer you extra credit (you'll still need to pay this back).
We'll set up a longer repayment plan if needed so you can pay this in weekly/daily instalments through your meter at an affordable rate. We’ll also give you details of where to go to get free independent advice.
