How do I register for supply?

It’s simple to register your business or farm, just contact us (if calling choose option 4, lines open Mon-Fri, 9am-5pm) and have all your information to hand.
Here’s what you’ll need:

  • If you are an existing or recent Power NI customer, your Account Number from the top right-hand corner of your bill

  • Your MPRN (Meter Point Reference Number). This will be on any previous electricity bill for the premises. If in doubt, call NIE Networks at 03457 643 643 (Mon-Fri, 8.30am-5pm)

  • The date when you took over responsibility for electricity in the premises

  • A photo of your electricity meter where the reading is clearly shown as well as the meter serial number

  • Your details (and any other persons of responsibility) and the business or farm’s details, including a company registration number where applicable

  • Your bank account name, account number and sort code. This is to allow us to set up your Direct Debit

If you’ve moved into premises where the previous occupant was with another supplier, we can still register you with Power NI. 

If you are moving out of another premises or closing an account, make sure to take a photo of your meter reading for the old premises and your new premises, showing the serial numbers of the meters. We would usually disconnect commercial supply when you close your account, please allow 5 working days for this appointment. For any reason the supply is required to be left on, you will need to provide your landlords details, the new occupier details as well as a forwarding address for yourself.


What are the payment options?

For new customers, Direct Debit is our preferred method and we offer discount for paying this way


What is the best tariff for my business?

For smaller businesses with under 70kVA supplies: 

  • Popular is best for mixed retail, offices and premises with 9-5 opening hours
  • Nightsaver is best for food retail, premises with storage heating or lots of fridges/chillers
  • Weekender is best for hospitality businesses and premises open mainly in the evenings and at the weekend


For larger businesses with over 70kVA supplies, there are two main choices: 

  • Multirate is a Seasonal Time of Day tariff with day, night, winter peak, evening & weekend unit rates
  • You may choose a market tracker option with no unit rates. Instead your half-hour consumption is matched to prevailing wholesale energy prices, network and market charges.


For further free advice on choosing your tariff, please contact us.

Do I need to pay a security deposit?

We may ask for a refundable security deposit and this is based on three months’ worth of electricity for your type of business.  

When you register with us, you can use electricity on day one, but you may not get billed until up to three months later. Like any business, we need to manage our exposure to debt and a security deposit is one way of doing this.

How do I close my account?

We would usually disconnect commercial supply when you close your account, please contact us (if calling, choose option 4, Mon-Fri, 9am-5pm) and allow up to 5 working days for this appointment. 

For any reason the supply is required to be left on, you will need to provide your landlords details, the new occupier details as well as a forwarding address for yourself.  Please also take a photo of your meter reading (with the meter serial number clearly displayed) before you move out, and then contact us. We will close your account and issue you with a final bill based on your meter reading. If you do not provide a photo of your meter reading when leaving the premises, this can delay closing your account.
