What IKM Consulting does

IKM Consulting, founded in 1997 and headquartered in Grangemouth, Scotland, was a multidisciplinary engineering and environmental consultancy. In December 2024, IKM Consulting merged with Mabbett & Associates to form Arthian Ltd, creating one of Scotland's largest multi-disciplinary consulting groups with approximately 200 employees across 19 offices in the UK and Ireland. The combined firm operates under the Arthian brand and delivers integrated consulting services across seven core areas: Environment (ecology, air quality, contaminated land, flood risk, archaeology, EIA, permitting), Engineering (civil, structural, geotechnical, process, asset integrity), Planning Consultancy, Safety (COMAH, DSEAR/ATEX, HAZOP, CDM, occupational hygiene), Sustainability Consulting (EHS compliance, ISO 14001/50001, ESG strategy), Net Zero and Decarbonisation (carbon footprint, Science-Based Targets, ISO 14068), and Energy & Decarbonisation (ESOS, energy engineering).

The firm's business model is professional services fee-for-service, with quote-based project pricing tailored to scope and client requirements, and no public pricing or software product offering. Its go-to-market is direct B2B engagement targeting enterprise and public sector organisations, with distribution via a 19-office regional network, a corporate website (arthian.com), dedicated contact channels (phone +44 (0) 3301 200 151, email [email protected]), and a LinkedIn corporate presence. Customer segments span public sector (local authorities, borough councils), manufacturing and industrial (distilleries, process operators), and energy and renewables (renewable developers, infrastructure operators), with named clients including Amber Valley Borough Council, Jackson's Distillery, Schroders Greencoat, and the EMphasis3 CO2 Reductions Programme. Following the merger, the firm has stated plans to open new offices in London and Pembroke, with its registered headquarters at 13 Henderson Road, Inverness, Scotland, operating under Scottish registration SC 163378.
