What GEP Environmental does
GEP Environmental Ltd is a UK-based energy and environmental consultancy headquartered in Winchester, formed in 2008 when Energy Management Solutions Ltd (founded 2004 by Glyn Mountford) merged with Green Energy Partners Ltd. The firm delivers climate-change and net-zero advisory, sustainability consulting for the built environment, and carbon/energy technical services — including ESOS compliance, SECR reporting, carbon footprint verification, Airport Carbon Accreditation, EPCs/DECs, measurement and verification under Investor Confidence Project standards, renewables feasibility, and ISO 14001/ISO 50001 management system implementation — to UK public sector bodies (local authorities, NHS, fire and police services, universities), hospitality and food-and-drink enterprises, and SMEs accessing government decarbonisation funds.
The company's commercial engine is professional services time-and-materials consulting sold primarily through public-sector procurement frameworks (12+ frameworks including LHC, Crown Commercial Service, Scottish/Welsh Procurement Alliances, ESPO, Greater London Authority, Scotland EXCEL, Business Energy Scotland, Fusion 21), which permit direct call-off without mini-competition by government buyers. GEP also operates programme-management mandates at scale — Re:fit Cymru for the Welsh Government (16 Service Providers under management) and the London Energy Project framework covering 35 public authorities — and a secondary revenue stream from open-enrollment IEMA-certified training courses (Carbon Footprinting, Net Zero Carbon pathways, IEMA Foundation Certificate, Technical Associate Certificate in Carbon Accounting with Arthian, and bespoke in-house courses) priced from £295 to £2,750.
The firm operates from four UK offices (Winchester HQ, Edinburgh, Cardiff, Caerphilly, Anglesey) with 11-50 employees, holds ISO 9001 and ISO 14001 certifications, and was acquired in June 2022 by Glasgow-headquartered Mabbett & Associates Ltd, a planning, design, environment, engineering and safety consultancy. GEP retains its operating brand within the Mabbett group.
