Power NI Top Up For Keypad Customers

Power NI keypad meter next to a Keypad card

Power NI Customers on the Keypad tariff - Power NI’s pay as you go option - will have to top up regularly to ensure that they preserve the supply of electricity into their homes. Here you will find the various methods through which you can top up and how, when purchased, to implement your Power NI top up.


To top up through any of the methods outlined in this guide you will need your Keypad card or the 19 digit Premise number found on the front of the card. If, for whatever reason, you cannot find your Keypad card and don’t remember the Premise number, contact Power NI’s Customer Service. Find the relevant contact information by heading to our Power NI Contact page.

Power NI top up without cardFor the purpose of topping up, you must provide the 19 digit Premise number on the front of your Keypad card. It is not necessary to present the card or have it to hand as long as you remember the code.

How do I top up my electric meter with my code?

What to do once you have your 20 digit Powercode? Simple. Head over to your Keypad meter with your Powercode to hand. Press the * key, then proceed to enter your Powercode. Upon completion of the code, press the # key. If you make a mistake whilst keying in your code, press the * key to delete a digit, then simply re-enter and press the hash key when finished.

  1. Press * key
  2. Enter your Powercode
  3. Press the # key to complete

If successful, you will receive a confirmation message on the meter’s display. If not, you may receive one of the following messages:

  • Duplicate” - You have previously entered the code attempted. Try again with a new code.
  • Incorrect” - Either you have keyed the code incorrectly or it corresponds to a different property (check the Premise number on your receipt).
  • "Error" - You have missed a number when keying in the code or you were too slow to enter it.
  • "Kblock" - The code has been keyed incorrectly five times in a row. Key in your code when the message disappears.
  • "Wrong Tar" - Electricity prices have changed; you must enter the special 40 digit Powercode from your latest purchase, or perform a new top up to get the code.
  • "Credit Hi" - You have too much credit, wait a few days and re-enter your code.

Useful Keypad features

You can access your Powercode history (last five Powercodes used) on your Keypad meter. If you perform multiple top ups and store them for future use, be sure to check your Powercode history to avoid “Duplicate” errors. To access your Powercode history, press the 4 key.

Additionally, you can check how much credit you have left by pressing the #; or to see home much credit you have left in days, based on your consumption of the preceding week, press 1.

If you are not quite sure how much to top up, take a look at the cost of the previous day’s, week’s or month’s consumption. Use this as a guide for subsequent top ups.


What if I’ve lost my Powercode?

If you have lost your top up code and haven’t yet entered it into your Keypad meter, there are a few ways to retrieve it. For PayPoint or Post Office top ups, take your Keypad card to the branch from which you purchased your top up.

For all top ups, regardless of the method, you can see your recent purchase by logging into your Energy Online account, selecting “Previous top up code” and then “Retrieve previous top up code”.

If you haven’t registered for Energy Online, you can use the ‘guest’ sign in feature. Head to the Energy Online login portal, scroll down, select “Top up or pay a bill without registering” and click on “View my previous top up code”. You will need to enter the last nine digits of your Premise number in the subsequent page before viewing your last purchase.
