Gas (Natural)

There is competition in the domestic gas market in the Greater Belfast and Larne.

This means domestic customers in these areas can shop around for their best price.

The Consumer Council has produced a leaflet explaining how to switch your natural gas supplier and have also produced an online gas price and service comparison tool.

Business customers in Belfast or Larne have the choice of three natural gas suppliers.

There is only one natural gas supplier to domestic and businesses customers in Antrim, Armagh, Banbridge, Craigavon, Newry, Ballymena, Ballymoney, Coleraine, Limavady and Derry.

All gas suppliers in Northern Ireland must keep a Customer Care Register with the details and special needs of customers who are of pensionable age, disabled (by virtue of being blind, partially sighted, deaf or hearing impaired) or chronically sick.  Suppliers can provide free assistance and services to customers who register their details with them. These services include bills in different formats such as large print or Braille and password schemes to help identify representatives from a service provider.

How you are protected

  • The gas industry is regulated by the Utility Regulator, which means that the supply companies have to work to rules set out in their licence.
  • Licensed companies are also required to set standards of performance e.g. how they respond to complaints and enquiries, offer customers connection to the gas network, respond to gas incidents and provide energy efficiency advice. They must also make clear their social obligations e.g. the services provided for pensioners, sick or disabled people.
  • The Consumer Council is an independent body, which represents and protects the interests of energy consumers and has the legal power to investigate complaints on your behalf.
