Whether you are a household, community group, small business or large company this section provides a range of information for you about electricity, gas and water and sewerage services.
Domestic customer information
As a domestic customer, you have a choice of suppliers (see supplier contact information page for details).
If you are interested in switching supplier you may wish to read a question and answer leaflet, produced by the Utility Regulator, Consumer Council and NIE Networks.
Did you know that NIE Networks and Power NI are separate companies? NIE Networks and Power NI are separate companies under different ownership.
NIE Networks is the electricity network business which owns the wires and meters and is responsible for transporting power to homes and businesses. If your electricity goes off or you have a problem with your electricity, you should contact NIE Networks. Power NI is one of a number of suppliers you can choose from - see our supplier contact information Page for details.
Electricity suppliers buy energy and sell it onto customers. Whoever your supplier is, they will issue your electricity bill and deal with any queries you have about your bill.
Suppliers need a licence from the Utility Regulator to supply electricity to customers in Northern Ireland. They buy energy from the all island electricity market (also known as the Single Electricity Market or SEM) and pay NIE Network ‘use of system’ charges to transport it over the electricity network to your home.
Customer Care Schemes
Suppliers offer a range of services to customers who have special requirements. If you are interested in signing up, contact your supplier for further information.
NIE Networks’ Critical Care Scheme
Customers who depend on electricity for life supporting electrical equipment can join NIE Networks’ Critical Care Scheme. Details of this are available from NIE Networks’ website at https://www.nienetworks.co.uk/Contact-Us/Critical-care-register.
Who is responsible for meter reading?
NIE Network is responsible for carrying out the reading, testing, installation and inspection of the meters of all electricity customers. The meter readings are then passed to your electricity supply company who will issue your bill.
