The Environmental Protection Group Limited

What The Environmental Protection Group Limited does

The Environmental Protection Group Limited (EPG), established in 1998 and headquartered in Bingley, West Yorkshire, is a UK-based geoenvironmental engineering consultancy operating as a subsidiary of STRI Group. The company specialises in sustainable drainage systems (SuDS) design, geoenvironmental assessment and remediation, continuous ground gas monitoring, and structural waterproofing design, serving property developers, water utilities, local authorities, contractors, and sports facility operators across the UK and selected international markets including the Republic of Ireland and the Middle East.

EPG's technical platform centres on the proprietary GasfluX continuous ground gas monitoring device paired with the Ambilytics analytics web portal, which uses AI-based anomaly detection across methane, CO2, oxygen, flow, and VOC data streams. The firm is also commercialising Polysync, a smart water controller integrated with Kisters' cloud forecasting intelligence for automated valve operation ahead of storm events, and a climate-resilient Blue Roof design capability demonstrated at the Stockport Interchange. EPG is co-author of the CIRIA SuDS Manual and a contributor to British Standards BS8576, BS8485, and CIRIA Reports C665, C735, and C748.

The business operates a professional services model combining engineering consultancy, integrated design-and-build delivery via the Carrick Construction partnership, training programmes delivered with CIRIA, CL:AIRE, the Landscape Institute, and the Geological Society, and product testing services for manufacturers. Pricing is project-specific and quote-based, with individual engagements ranging from approximately £60,000 to £2 million. Revenue is not publicly disclosed, and the company has been expanding through acquisition (Hafren Water, 2025), board expansion, and a new North West office in 2025.
