A number of installer schemes have been developed whose aim is to verify the competency of installers carrying out improvements to dwellings. Grant aid may be available for building improvements under the Sustainable Energy Authority of Ireland’s About Better Energy Homes (Formerly Home Energy Saving Scheme). All works must be designed and installed as per the National Building Regulations.
