Envirotec

What Envirotec does

Envirotec Limited is a privately held British designer, manufacturer, and installer of air improvement systems, founded over 50 years ago (1969) and headquartered in High Wycombe, Buckinghamshire, UK, with 11–50 employees. The company's core product portfolio comprises air curtains (over-door, vertical designer, and industrial Distribution Fulfilment & Warehousing units up to 10 metres), custom-built Air Handling Units (AHUs) including the Liberty Composite AHU, destratification units, air barriers, and commercial heating solutions. Differentiated technology includes energy-efficient EC fans with Variable Air Volume control, heat recovery systems (thermal wheels and cross plate exchangers), and the proprietary Enetec 18 intelligent controller with Building Management System (BMS) connectivity for automated fan and heating modulation. The company holds the Chair position of the FETA group for Air Curtains, an industry standards body.

Envirotec operates a sales-led, project-based business model targeting enterprise customers across at least 13 verticals: retail (Tesco, John Lewis, Selfridges, H&M, Metquarter, Gieves & Hawkes, BOSS), healthcare (NHS hospitals), financial services (Barclays), pharmaceutical (Napp Pharmaceuticals), manufacturing, education, transport, leisure, luxury residential, hospitality, warehousing, data centres, and public sector/government. Pricing is quote-based, with multi-year installation and maintenance contracts; the company emphasises refurbishment services at 35–50% of replacement cost as a recurring revenue lever. Distribution is direct-to-customer within the UK only, with no disclosed international footprint, third-party resellers, or app/digital channels. Go-to-market is supported by content marketing (Knowledge Hub blog, case studies), CIBSE-accredited CPD presentations, an Air Curtain Selector online tool, and expert consultation via phone and email.

The company is bootstrapped, with no disclosed external funding, parent company, or institutional investors, and operates as an independent private limited company in England. Its claimed installed base spans 10,000+ locations across the UK (a more conservative figure than its headline '100,000+' marketing claim). Products are entirely designed and manufactured in Great Britain, and the company cites over 50 years of accumulated engineering expertise and project references as its principal competitive differentiators.
