Connecting to the electricity network and choosing an electricity supplier.

Connecting to the electricity network

If you want to connect your home to the electricity network you need to contact NIE Networks. The company will explain the process and provide the application form that you will need to complete.

You can shop around for some of the connection work. NIE Networks will give you a list of accredited electrical contractors so that you can obtain additional quotes. These are known as Independent Connection Providers (ICP). 

The connection process can be quite lengthy as it requires significant planning and design and may require planning permission or approval from landowners. If you are planning to build a new property, you should contact NIE Networks as soon as possible.

Choosing an electricity supplier 

Domestic consumers in Northern Ireland are able to choose their electricity supplier. There are currently five suppliers operating in the domestic market; Budget Energy, Electric Ireland, Power NI, SSE Airtricity and Click Energy.

Marketing Code of Practice

All electricity suppliers must adhere to the Utility Regulator's Marketing Code of Practice. This protects electricity customers, in particular vulnerable customers, from inappropriate marketing practices and guards against the mis-selling of products.

Guaranteed Standards of Service

Electricity network operator, NIE Networks and electricity suppliers have guaranteed standards of service. These standards let you know how companies should perform in the event of a complaint or network problems, and include payments to customers should they fail to meet them. There are some exceptions to the guaranteed standards and the company may not have to make a compensation payment in all instances.

For a full list of the Guaranteed Standards of Service see the network distributor/supplier website or our factsheet.

Consumer Rights Act 2015

All businesses that deal with consumers have the legal responsibility to ensure that their terms and conditions are fair.  All energy companies in Northern Ireland have stated that they are compliant with the terms of the Consumer Rights Act 2015

Fuel Mix

Each electricity supplier in Northern Ireland purchases its electricity from different sources. The most common source is natural gas, followed by renewable, mainly generated by wind turbines. This table shows where the electricity that your supplier sells you comes from.
