What Wardell Armstrong does
Wardell Armstrong is a UK-based multidisciplinary environmental, engineering, and mining consultancy founded in 1837 (per firmographic data; an alternate source records 1839) and headquartered in Stoke-on-Trent. The firm delivers environmental consulting, engineering consulting, mining consultancy, and archaeology/heritage services to clients in the UK and internationally, with operational presence in cities including Nottingham and Birmingham. Its service model is project-based, delivered directly to enterprise clients across infrastructure, mining, and development sectors, and its revenue is generated through professional services fees rather than product or licensing models.
The firm employs approximately 550 specialists across environmental, engineering, mining, and archaeology disciplines, positioning it among the larger UK consultancies in its niche. Its go-to-market is enterprise field sales — direct engagement with blue-chip clients on long-cycle, multi-phase projects. In October 2024, Wardell Armstrong was acquired by SLR Consulting, a global sustainability and environmental consultancy, forming a combined European team of nearly 1,800 colleagues; Caroline Mellor leads as EU Regional Service Line Director for Environmental Sciences, and Alison Allen leads as Mining & Minerals Sector Leader for EMEA. Post-acquisition, the firm operates as part of SLR's European region rather than as an independent entity.
