Installing natural gas and choosing a natural gas supplier.

Installing Natural Gas

If you want to install natural gas in your home or businesss you should contact the relevant gas distribution company to see if they operate in your street:

For Greater Belfast and Larne - contact Phoenix Natural Gas on: 03454 55 55 55 or visit the website at

For Antrim, Armagh, Banbridge, Craigavon, Newry, Ballymena, Ballymoney, Coleraine, Limavady and Derry - contact firmus energy on: 0800 032 4567 or visit the website

Connecting your home to the gas network is free with both firmus and PNG, so long as it is a straightforward connection (conditions apply - contact firmus or PNG for details).   However, you will have to pay for a new gas boiler and any internal plumbing and radiators that may be needed. Information on how you may be able to get help to reduce these costs is available in our Energy Efficiency Schemes section.

Marketing Code of Practice

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

These standards let customers 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.
