Residential pricing

What is happening?

The price you pay for electricity is increasing by 4% on 1 October 2025.

Even though global wholesale energy costs have stabilised in recent months, there has been an increase in other market and network related costs.

What does this mean for me?

This means that you will see an increase of 4% to the price you pay, which means on average you will be paying around 11p more per day.*

Power NI is the only regulated electricity supplier that is price-regulated by the Utility Regulator. This means that they review and agree any changes to our tariffs, ensuring that you pay a fair price.

I am a Keypad customer, what do I need to do?

From 16 September 2025, when you buy a top-up, you will get a 40 to 60 digit price change code.
Enter this into your meter and then press the # button.
Your meter will then switch to the new rate on 1 October.

Please note, you must enter this longer code before any further top-up codes can be accepted.

For Keypad+ customers, please see our FAQs below.

- Keypad customers get 2.5% discount off every unit of electricity used. On top of this, you can get free electricity with our Keypad Reward. Just top-up £50 or more online or via our app.
- Save on everyday purchased with Power NI Perks: We’ve also negotiated discounts and savings for Power NI customers with hundreds of everyday big brands such as Tesco, Asda, Sainsbury’s and M&S.
