Stothers

What Stothers does

Stothers (M&E) Limited is a privately held, Northern Ireland-founded mechanical and electrical building services contractor operating across the United Kingdom and the Republic of Ireland. Established in Belfast in 1957, the company plans, designs, installs, commissions and maintains M&E systems for new-build and retrofit projects spanning healthcare, education, custodial/defence, heritage, hospitality, commercial, industrial and high-rise residential sectors. Headcount is over 100 direct employees supplemented by a supply chain of more than 1,000 approved suppliers and sub-contractors, with four offices (Belfast HQ, Bellshill, Warrington, London) and supporting infrastructure in Dublin and Edinburgh; annual turnover exceeds £50 million.

The company's technical offering sits across five integrated service lines: Building Services (core M&E installation), Design & Build (full lifecycle including state-of-the-art CAD systems), Digital Design/BIM (cloud-based Common Data Environment integration with multi-disciplinary data and real-time collaboration), Contract Maintenance (24/7 reactive and pre-planned cover, NICEIC inspection and certification, periodic appliance testing via 100+ trained engineers), and Sustainable Technologies (rainwater harvesting, ground and air source heat pumps, PV, solar water heating, thermal imaging, smart metering, off-site fabrication). Quality, environmental and safety systems are certified to ISO 9001, ISO 14001, SSIP and CHAS standards.

Commercially, Stothers operates as an enterprise-field-sales specialist subcontractor engaged directly by blue chip main contractors (Henry Brothers, Graham Construction, McLaughlin and Harvey, Gilbert Ash) on projects typically ranging £1M to £20M+, with long-standing repeat business built over decades. Distribution is via direct engagement with main contractors and via direct maintenance contracts with end clients (Ulster Bank framework £5M+; Hastings Group works exceeding £250K per annum). The business has undergone two management buyouts (1999/2000 by Marley, Preston and Ellis; 2009 by Cherry and Megarry) and remains under founder-era management ownership with no external private equity or venture capital involvement disclosed.

• EQUANS (formerly Imtech): Major facilities management and building services provider with significant M&E capabilities across UK. Larger and more diversified than Stothers, but overlapping capabilities and customer segments make it a relevant incumbent benchmark.
• Bowmer + Kirkland: UK construction group with significant in-house M&E capability delivering projects across commercial, education, hospitality, and heritage sectors. Larger scale but directly comparable customer mix and integrated services model.
• Balfour Beatty: Major UK and international infrastructure group with significant building services work. Much larger scale incumbent providing relevant public-sector benchmark, though diversified across civil engineering and infrastructure beyond M&E building services.
• Wates Group: UK construction group with substantial M&E services capability serving commercial, education, healthcare, and government sectors. Operates more broadly across the construction lifecycle but overlapping customer base.

Regional players

• McLaughlin & Harvey: Northern Ireland-headquartered construction firm with significant M&E capability and shared NI heritage. While broader in scope than Stothers, the geographic roots and overlapping customer relationships (e.g., NIPS, universities) make it a relevant regional comparable.
