NetZero Group is an Irish energy solutions group formed by bringing together eight specialist companies with decades of experience in heating, insulation, solar, ventilation, and new-build mechanical services. Operating across three divisions—New Build, Retrofit, and Service & Solar—the group provides integrated, whole-system energy solutions for residential, commercial, and public sector clients across Ireland.
NetZero Group serves residential developers, housing associations, local authorities, commercial building owners, and private homeowners. Our three divisions cover new-build residential and commercial projects, retrofit upgrades supported by SEAI schemes, and ongoing service and solar PV installations giving clients a single partner for the full lifecycle of their building’s energy systems.
NetZero Group operates nationwide, with locations in Dublin, Galway, Cork, Mallow, Drogheda, Kells, Naas, Dungarvan, and Ballycoolin. This geographic spread allows us to respond quickly to clients across the country and support large-scale programmes with regional teams who understand local planning, building stock, and market conditions. As a group of 8 specialist companies, this regional presence is matched by the technical depth and delivery capacity of a national organisation.
