RGI (Registered Gas Installer) is the statutory register for gas work in Ireland. Under the Energy (Miscellaneous Provisions) Act 2006 it is an offence for anyone who is not RGI registered to carry out notifiable gas work such as a boiler installation or gas appliance connection. Every installer on this directory is drawn from the RGI public register.

Yes. Installing or replacing a gas boiler, connecting a gas appliance or altering gas pipework legally requires an RGI registered installer. Using an unregistered person is illegal, voids most home insurance, and means the work cannot be certified with a Declaration of Conformance.

As a national guide, a like-for-like gas combi replacement runs about €2,200 to €3,200, an annual boiler service €80 to €120, a gas safety certificate €80 to €150, and an emergency call-out €80 to €180 depending on the hour. Always get the call-out fee and a written quote before the work starts.

Natural gas is piped from the Gas Networks Ireland grid and is common in towns and cities. LPG is delivered by tank or cylinder and is the usual alternative for rural homes off the grid. LPG needs separate certification, so 863 of the installers listed here hold LPG certification alongside their RGI registration.

Ask for the RGI registration number and check it on the official register at rgi.ie, which lets you search by number. Confirm the entry is current rather than expired before booking. A genuine registered installer will have no problem giving you the number.

All 26 counties of the Republic of Ireland. Each county has its own directory page with local RGI installers, their registration numbers, the towns they cover, and county-specific gas and cost information.

Do not use switches or naked flames, open windows and doors, turn off the gas at the meter if safe, and ring the Gas Networks Ireland emergency line on 1800 20 50 50 before calling anyone else. Only an RGI registered installer should investigate and repair a gas fault.
