Quinn Downes Group

What Quinn Downes Group does

Quinn Downes Group is an Irish mechanical engineering services company headquartered in Dublin, operating through two core divisions: Quinn Downes Installation, which delivers HVAC, heating, ventilation, air conditioning, water services, medical gas systems, building management systems (BMS), fire protection, and specialist data-centre cooling for new-build and refurbishment projects; and Quinn Downes Service & Maintenance (QDSM), which provides planned preventative maintenance (PPM), 24/7/365 emergency response, mechanical and electrical surveys, and single-source hard services across mechanical, electrical, BMS, lifts, escalators, automatic doors, and medical/industrial gas systems. Established in 1999 and reorganised into the current Group structure in January 2015, the Group employs over 130 staff and serves healthcare, education, corporate, retail, hospitality, public-sector, vocational, and residential clients across Ireland, with documented projects ranging from €98K to €22M and a portfolio of 150+ maintenance clients.

Revenue is generated through two primary streams: project-based mechanical installation contracts awarded via competitive tendering, framework agreements (e.g., Office of Public Works, HSE, major universities), and negotiated enterprise deals; and recurring subscription-style PPM contracts with annual billing, supplemented by usage-based 24/7 emergency call-out services and professional-services M&E surveys. The go-to-market is direct enterprise sales with all services delivered by directly employed staff or vetted sub-contractors; no resellers or distributors are used. In March 2026, QDG entered a strategic partnership with international refrigeration network Syclef (subject to CCPC approval), marking Syclef's entry into Ireland and positioning QDG within a pan-European refrigeration platform while preserving existing director ownership and operational autonomy.
