Electricity Bills - Easy To Understand & Discounted Electricity Bills | Power NI

Home > My Home > Bills


We want to make sure that keeping track of your electricity costs is as easy as possible. That’s why we have a bill layout explaining all the different elements of an electricity bill.

We issue a customer bill every 3 months for electricity you have used. Payment is due within 14 days and you can choose from a range of payment options.

Payment Methods


Direct Debit

Monthly Direct Debit
This is perfect if you want to spread out the cost of your electricity into smaller monthly payments so you don’t get higher bills in Winter. You agree to the amount to pay each month and you can make a saving of up to £40 a year. That’s a 4% discount on your bills.

Quarterly Direct Debit
If you would prefer to pay every 3 months then you can pay 14 days after the bill date and save up to £26 a year. That’s a 2.5% discount on your bill.

It only takes around 3 minutes to sign up to Direct Debit. Remember that’s potentially a saving of £40.



This is a quick and easy way to pay your bill online using your debit card with no need for registration.

High Bills

If you receive a higher-than-usual bill, many customers suspect their meter may be faulty, however this is very rarely the case. Before calling our Helpline about a high bill please check you have considered the following:

  • Was your last bill estimated (it may have been a low estimate and this bill is only now ‘catching up’ on actual readings)?
  • Are you comparing a winter bill to a summer bill? After all it’s only natural to use more electricity when the days are shorter and nights longer.
  • Has there been a recent change of routine at home? Maybe you’ve had a new child or a university graduate has moved back home.
  • Have you installed any new equipment, for example a tumble drier or an electric heater?
  • If you have carried out these checks and still think your bill is too high, please get in touch and we will do all we can to sort out any problems there and then.
