SLR Consulting

SLR Consulting

Founded in 1994, SLR Consulting operates as a global environmental and advisory firm, delivering technical due diligence, ESG strategy, permitting, and site remediation to clients across mining, energy, built environment, and financial services. The firm originated in the UK but expanded over three decades principally through serial M&A, integrating specialist consultancy teams in North America, Europe, Asia-Pacific, and Africa. SLR advises on the full asset lifecycle, from early-stage environmental impact assessments and social license work through operational compliance to closure planning and rehabilitation. Its technical bench covers air quality, water management, acoustics, ecology, geotechnical engineering, and waste management. The firm also runs a growing transaction services practice, providing environmental liability assessments and ESG reviews for institutional investors, infrastructure funds, and lenders evaluating real assets, brownfield redevelopment, and natural resources deals. Headquartered in Aylesbury, the firm is structured as an employee-owned company with a professional partnership ethos, operating from dozens of offices internationally after a long consolidation run that included the 2016 merger with RPA Inc. in Canada and multiple tuck-in acquisitions in geology, marine science, and risk advisory. SLR’s client base spans the largest global mining houses, mid-cap energy developers, UK water utilities, and private credit providers writing infrastructure debt. Structurally, SLR differentiates through its multidisciplinary employment model — keeping engineers, hydrogeologists, ecologists, and social scientists under one roof — which allows the firm to bid on complex, multi-jurisdictional projects that boutique competitors cannot resource. Its employee-ownership structure also aligns retention in an industry where technical talent churn determines throughput on multi-year permitting and monitoring contracts.
