Alternative Heat

Alternative Heat Ltd. designs, manufactures and delivers turnkey prefabricated mechanical and electrical (MEP) solutions, and describes itself as an established market leader in offsite prefabrication. Founded in 2005, the company has operated for over two decades, applying Modern Methods of Construction (MMC) and Design for Manufacture and Assembly (DFMA) practices to produce higher-quality projects with reduced programmes. Annual turnover stands at £130 million and growing, with average project values exceeding £10 million.

For data centre clients, the company's offering centres on packaged plantrooms - turnkey plantroom solutions designed, manufactured and delivered offsite - alongside prefabricated plant skid modules and MEP lateral and riser modules for mechanical and electrical services. These products support fast-track MEP installation on large, complex schemes where programme compression and quality consistency are critical.

The firm's technical domains span offsite prefabrication, prefabricated MEP design and manufacturing, mechanical and electrical engineering, and renewable energy systems. A dedicated Renewable Energy Division provides bespoke solutions for biomass, air source heat pump and ground source heat pump technologies, supporting the transition to cleaner energy systems.
