The Green Consultancy

What The Green Consultancy does

The Green Consultancy Inc. Limited (GCI) is a privately held UK energy efficiency consultancy founded in 2012 and headquartered in Ashford, Kent. The company provides a turnkey offering to commercial, public-sector, and industrial customers, combining advisory services (energy procurement via a reverse-auction system, meter operator and data collection management, retrospective profit recovery on utility invoices, and TM44 air conditioning inspections) with a portfolio of proprietary and partner hardware technologies. Core technology is anchored by the patented Dynamic Burner Management Unit (DBMU), the only BRE-certified boiler optimiser, which alters firing patterns to deliver 16-25% fuel savings with 5-18 month payback. The product set is rounded out with Endocube refrigeration controllers, LED lighting, variable speed drives, combined heat and power, fan unit upgrades, monitoring and targeting software, valve wrap insulation, and solar PV project development.

GCI's revenue mechanics are mixed: professional services fees (procurement, billing recovery, MOP/DC management), hardware sales and installation, commission through a partner introducer program, and project origination fees on solar PV developments funded through an institutional finance panel with over $5 billion in capital capability. The "zero cost energy efficiency" model packages solar PV installation with energy-efficient hardware into long-term electricity purchase contracts, removing upfront cost barriers for clients. Customer base spans hundreds of UK businesses since inception, with named deployments in hospitality (Hilton, Andaz, Marriott, Arora), healthcare (Cardiff & Vale UHB, NHS sites), education (academies), government (local authorities), and military (RAF Mildenhall), alongside international solar PV project activity across Europe, the Americas, and the Caribbean.
