Henderson Warnock

What Henderson Warnock does

Henderson Warnock is a privately held UK building services engineering consultancy, founded in 1993 in Glasgow. It designs Mechanical, Electrical and Public Health (MEP) systems for commercial offices, student accommodation, luxury hospitality, residential, and government buildings, with a four-stage delivery process covering Understand & Define, Design & Coordinate, Deliver & Support, and Optimise & Future-Proof. The firm operates from three UK offices (Glasgow HQ, Leeds, London) and has completed over 3,000 projects for 300+ clients, including Aldi, M&G, Barclays, Ministry of Justice, Mar Hall, Pinners Hall, and Vita Student.

Core services are Mechanical Engineering, Electrical Engineering, ESG & Sustainability, and Utilities & Infrastructure consultancy. Notable technical capabilities include BIM-led digital delivery with federated MEP models and clash detection, sustainability/Net Zero Carbon integration with Part L/Part F/Section 6 compliance, and decarbonisation solutions such as Air Source Heat Pump central energy centres achieving 60-70% operational carbon reduction and LED/lighting controls delivering 40-60% energy savings. The firm positions itself as director-led — Electrical Director Thomas Lennie and Mechanical Director Peter Low personally oversee projects — distinguishing it from larger, more process-driven competitors.

Henderson Warnock earns revenue through professional-services consultancy fees for MEP engineering design, technical due diligence, commissioning and construction support, pricing not publicly disclosed and typically scoped per-project. Distribution is direct enterprise engagement by directors and senior staff with developers, main contractors (e.g., GRAHAM Construction), institutional operators, government clients and facilities managers (e.g., OCS). Lead generation relies on a UK-focused website portfolio, LinkedIn presence, and a contact form / quote request — a deliberately lean, relationship-driven channel mix rather than a scaled demand-gen model.
