Gas and Heating Installer

Gas and heating installers must be registered with the Register of Gas Installers of Ireland (RGII).

The Energy (Miscellaneous Provisions) Act 2006 makes it illegal for any person who is not a Registered Gas Installer (RGI) to undertake "Gas Work". It is also a legal requirement for all RGIs to issue a Declaration of Conformance (completion cert) for all "Gas Work" carried out. Individuals who carry out "Gas Work" and who are not registered will be subject to criminal proceedings.


To be eligible to join the Register you must show proof of training and qualifications. (level 6 advanced craft certificate in Gas Fitting, Electrical, Plumbing or Refrigeration or equivalent).

Trainees/apprentices must also register but applicants must show evidence of education/training achieved to date and must also be in a position to nominate a supervisor(s) who will take responsibility for supervising work and signing off completion certificates issued by the trainee.
