What Mastertech does
Mastertech Group Limited is an Irish building services engineering company founded in 1989 and headquartered in Tallaght Business Park, Dublin 24. It operates three core service divisions: HVAC (heating, ventilation, and air conditioning), MEP (mechanical, electrical, and plumbing), and Sustainable Solutions (Solar PV and EV charging infrastructure, launched in November 2023). Underlying technical capabilities span installation, planned preventative maintenance (PPM), reactive maintenance, and bespoke project delivery across AHUs, fan coil units, chillers, boilers, heat pumps, BMS systems, and proprietary liquid cooling technology for data centres. The company maintains a comprehensive certification stack — ISO 9001, ISO 14001, ISO 45001, Safe-T-Cert, Safe Contractor, Avetta, F-Gas, RGII, and Safe Electric — and holds Mitsubishi Electric Partner Programme certification for 2025.
The business serves enterprise and government clients across the Republic of Ireland in sectors including data centres, hospitality, healthcare and pharma, facilities management, commercial real estate, construction, beverage manufacturing, and government. Named customers include Carton House (€4M project), The Marker Hotel (€3.25M project), GSK, Diageo, Irish Distillers, HSE, OPW, An Post, CBRE, Cushman & Wakefield, Savills, BAM, Sisk, Mitie, Hollis, Metec, and Gemini Data Centre. The go-to-market combines direct enterprise field sales, inside sales via phone and email, tender-based procurement for government and large corporate contracts, and a self-serve website quote request flow for Sustainable Solutions.
Mastertech generates revenue primarily through professional services contracts for HVAC and MEP installation and maintenance, recurring multi-year maintenance contracts providing 24/7/365 cover (subscription-style annuity), and hardware-based Sustainable Solutions sales with financing facilitated through a Finance Ireland Green Lending partnership. Pricing is quote-based and customised by project scope and site requirements. The company is privately held, underwent a management buyout in 2014 led by Managing Director Shay McConnell and Director Aidan Conway, and reports approximately 40+ employees based on a 2016 disclosure, with no recent headcount or revenue figure publicly disclosed. Recognised as the FM Awards Specialist FM Service Provider of the Year 2024 and shortlisted across multiple categories in 2025.
