APEM

What APEM does

APEM is a global environmental and geospatial consultancy established in 1993 and headquartered in Stockport, United Kingdom, with employee headcount in the 501-1000 range. The firm delivers independent environmental consulting services to government bodies, environmental regulators, and industrial clients, with core capabilities spanning freshwater and marine ecological surveys, environmental impact assessments, protected species surveys, laboratory analysis, geospatial analysis, and landscape visualisation. Its technical foundation rests on high-resolution digital aerial wildlife surveys whose methodology is cited as the UK benchmark for offshore wind projects, world-renowned laboratories providing external quality assurance for marine biological sample analysis, environmental DNA technology for species detection and biodiversity assessment, and 3D environmental modelling for visualization and planning support.

The firm's commercial model is a B2B project-based professional services engagement model, with pricing determined on a project-by-project basis and not publicly disclosed. APEM acquires customers primarily through direct website enquiries, professional content marketing (blogs, case studies, webinars, news), social media channels (LinkedIn, Twitter, Instagram), and participation in industry events targeting government, regulators, and enterprise industrial buyers. Revenue is generated across seven verticals: water, renewables, power and utilities, marine and ports, construction and development, transport, and environmental regulation, with the renewables and government/regulator segments highlighted as primary.

APEM Ltd operates as the principal UK entity within APEM Group, a private-equity-backed (WestBridge) holding structure consolidating multiple acquired environmental consultancies across the UK, Ireland, continental Europe (Italy via Ambiente srl), North America (US via CSA Ocean Sciences), and Australia (AARC, Attexo, Biosis). Since 2021 the group has completed at least six acquisitions including Aspect Ecology (October 2023, terrestrial ecology), Nash Maritime (July 2023, maritime and offshore wind), CSA Ocean Sciences, Ambiente srl, AARC, and Aquafact (February 2022), while retaining the acquired brand identities within a federated multi-brand ecosystem.

• WSP Global: Global engineering and environmental consultancy with deep environmental impact assessment, ecology, and geospatial capabilities. Directly comparable to APEM across renewables, infrastructure, and marine sectors but operates at vastly greater scale as a multi-disciplinary incumbent.
• AECOM: Global infrastructure consulting firm with a substantial environment practice spanning ecology, marine sciences, and permitting. Competes with APEM for renewable energy and infrastructure EIA work but offers broader engineering and design capabilities.
• Jacobs Solutions: Major engineering, environmental, and program management consultancy with strong water, environment, and infrastructure practices. Overlaps with APEM in environmental impact assessment and water-sector ecological services for government and industrial clients.
• Ramboll: European engineering, environmental, and health consultancy with strong renewables and offshore wind EIA capability. Highly comparable to APEM in Northern European offshore wind environmental services, though Ramboll operates as a broader multi-disciplinary firm.
• Royal HaskoningDHV: Dutch engineering and environmental consultancy with strong marine, coastal, and offshore wind capabilities. Direct overlap with APEM's marine ecology, navigational risk, and offshore wind surveying services in European markets.
• Stantec: Global engineering, architecture, and environmental services firm with established water, ecology, and environmental assessment practices. Comparable to APEM across water industry, infrastructure EIA, and environmental permitting in North American and European markets.

Direct peers
