What APEM LIMITED does
APEM LIMITED is a UK-based environmental and geospatial consultancy, founded in 1987 and headquartered in Stockport, that delivers ecological surveys, laboratory testing, and environmental impact assessment services. Its primary served vertical is offshore wind developers in the United Kingdom, for whom it provides seabed habitat mapping, seabird surveys, marine mammal surveys, and broader marine environmental assessment and biodiversity monitoring required for regulatory consenting and project planning. The firm operates as a professional services consultancy with a workforce of 501–1,000 employees, combining field survey, in-house laboratory testing, and geospatial analysis capabilities to produce environmental evidence packages for energy infrastructure clients.
The company's most significant recent programme is POSEIDON, a four-year initiative completed across 2022–2026 under the Offshore Wind Evidence and Change Programme, which mapped approximately 750,000 square kilometres of UK waters, captured imagery of more than 54,000 seabirds and more than 5,000 marine mammals, and collected over 13,000 seabed samples. All POSEIDON survey outputs are being made publicly available through The Crown Estate's Marine Data Exchange, and APEM is extending this asset with an online mapping tool scheduled for public launch in Summer 2026. This positions the firm as both a survey contractor and, increasingly, a steward of a national-scale marine biodiversity dataset that underpins UK offshore wind consenting.
APEM's business model is services-led rather than product-led: revenue is generated through project-based environmental consulting and survey contracts, with the Crown Estate and the UK offshore wind sector acting as anchor counterparties. Pricing, contract structures, revenue figures, ownership, and named end customers are not disclosed in the available sources. Limited marketing, distribution, and partnership information is publicly available, and the company's website was not accessible at the time of data collection, restricting visibility into go-to-market mechanics, customer logos, and certifications.
