What RGI registration means

RGI stands for Registered Gas Installer. For gas work in Ireland, registration is the key safety check for homeowners because gas appliances and pipework carry carbon monoxide, fire, and explosion risks if installed or serviced incorrectly.

The official RGI register lets homeowners check whether an installer is currently registered. For boiler work, gas cookers, gas fires, or gas pipework, verify the installer before allowing work to begin.

Gas works registration is currently covered by S.I. No. 225/2009 - Electricity Regulation Act 1999 (Gas Works) Regulations 2009, made under powers inserted by the Energy (Miscellaneous Provisions) Act 2006. S.I. No. 106/2026 - Electricity Regulation Act 1999 (Gas Works) Regulations 2026 has been made and comes into operation on 1 September 2026, replacing the 2009 regulations from that date.
