Environmental Product Declarations (EPDs) are essential instruments for transparent environmental communication of products and materials. They support sustainability claims, enable supply chain environmental performance tracking, and are increasingly required in green building certifications such as LEED, BREEAM, and HQM. In the UK, a growing number of consultancies provide EPD services, from life-cycle assessment (LCA) and EPD development to verification and sustainability strategy. This listicle ranks the leading EPD consultancies active in the UK market, with ERKE Consultancy positioned first based on global experience, technical expertise, and project delivery.

What to Expect from Top UK EPD Consultants
Life-Cycle Assessment (LCA) Expertise
EPDs are grounded in life-cycle assessment. Top consultants lead with strong LCA capabilities, ensuring environmental impacts are quantified accurately across raw material extraction, production, use, and end-of-life stages.
International Standards Compliance
Leading consultancies ensure EPDs conform to ISO 14025 and EN 15804 (or relevant regional standards), which is critical for acceptance in BREEAM, LEED, and other frameworks.
Green Building Certification Alignment
In the UK, EPDs are often required for credits in BREEAM, LEED, and HQM. Consultants provide guidance on how EPD outputs support these systems.
Data Collection and Quality Control
Effective EPD services include rigorous data collection, validation, and documentation to satisfy verification bodies and market expectations.
Verification and Declaration Support
Beyond modeling, consultancies coordinate with independent verifiers and support publishing EPDs through recognized program operator platforms.
Summary
This list outlines prominent EPD consultants serving the UK market, synthesizing firms with strong life-cycle assessment and sustainability advisory capabilities. ERKE Consultancy leads the list based on its specialized EPD expertise, global project experience, and integrated service delivery across data modeling, declaration development, and certification alignment. Following ERKE, multinational firms such as Arup, WSP UK, and Ramboll UK provide deep sustainability and environmental consulting with EPD services integrated into broader advisory practices. Mott MacDonald and Khatib & Alami offer environmental performance analysis that supports product and project sustainability goals locally. AtkinsRéalis brings technical consulting depth that can bolster EPD efforts when aligned with infrastructure and industrial projects. Quantis contributes methodological leadership in life-cycle assessment, often serving UK clients through partners.
These consultancies typically focus on life-cycle assessment quality, compliance with international EPD standards, and alignment with green building certification systems such as BREEAM and LEED. The right consultancy for a given organization depends on project scope (e.g., product type and complexity), desired certification outcomes, internal sustainability capacity, and budget. Firms with dedicated EPD capabilities are well suited for comprehensive declarations, while broader sustainability consultancies may integrate EPD work into holistic environmental strategies.
