What SE Systems does
SE Systems Ltd is an Irish energy retrofit contractor and SEAI-approved One Stop Shop founded in 2011 in Cork. The company delivers end-to-end energy upgrade services — including solar PV installation, deep retrofits (insulation, heat pumps, windows, doors, ventilation), energy audits, EV charging infrastructure, and SEAI grant facilitation — across residential, commercial, community, and public-sector clients nationwide in Ireland. Operations are organised through a Cork headquarters (opened July 2026) and a Dublin office, with 55 employees at the time of latest disclosure and a stated plan to add up to 150 jobs over the following two years.
The underlying service model is integrated project delivery: SE Systems performs the initial energy assessment, coordinates SEAI grant applications and credit-union green financing, manages trades and installation, and commissions completed works. Customer segments span enterprise (Tesco, ESB Networks, SSE Airtricity, Dunnes Stores, Lilly), public sector (Cork City Council, Bus Eireann), community and nonprofit organisations (Barretstown, Down Syndrome Ireland, Irish Guide Dogs for the Blind, Douglas & District Lions Club), and a high-volume residential book (1,200 homes retrofitted in 2024). A branded Community Fund, funded by commercial project margins and awarding €500,000 to 45 community organisations in 2025, functions as both a brand-building mechanism and a lead-generation channel.
Revenue is generated through professional services (energy audits, project management, grant coordination) and hardware installation (solar PV and battery storage), with unit pricing for residential solar PV at €1,500–€2,000 per kW before VAT and SEAI grants reducing customer out-of-pocket cost. SEAI grant facilitation and credit-union partnerships (Elevate Credit Union, Cobh Credit Union) are core to the value chain because they convert technically complex funding pathways into a single-vendor experience. The company is privately held, with no disclosed external funding rounds, and is led by co-founders John O'Leary (CEO) and Youenn Lowry (Managing Director).
