Clade Engineering Systems | B Corp™ operates a UK factory where engineering, assembly, testing, and quality control occur under one roof to produce commercial heat pumps.

Clade is a UK-based B Corp on a mission to decarbonise how buildings are heated. We design, manufacture, install and maintain high-performance air source heat pumps, built in Britain and powered by natural refrigerants. Our technology helps consulting engineers, operators, facilities managers and contractors decarbonise buildings with reliable, future-proof, low-carbon systems that perform. Every Clade system is built with CO₂ or propane (R290), natural refrigerants that deliver efficiency, safety and measurable carbon reduction. From early design to aftercare, our UK-based engineering team stays hands-on, ensuring every system is reliable, efficient, and tailored to each site, delivering solutions that simply work. Backed by over 30 years of experience and deep engineering expertise, we’ve earned the trust of major UK brands and public sector partners. With a focus on customer-first service and scalable clean tech, we help partners across commercial, industrial and public sectors cut carbon with confidence. Our vision? A carbon-neutral built environment, made possible by Clade. Want to hear more? Contact us to speak with a Clade Engineer: https://clade-es.com/contact/
