What I O M does

IOM (Institute of Occupational Medicine) is an independent Scottish research charity founded in 1969, originally established by the National Coal Board to investigate lung disease in coal miners. It has been self-funding since 1990 and today operates as a 101–250-person organisation delivering scientific research, consultancy, and accredited laboratory services in occupational and environmental health. The core proposition is independent, science-led advice on exposure assessment, hazardous substance control, hospital ventilation, and policy evaluation, delivered to employers, regulators, healthcare providers, and the legal sector. Service lines include occupational hygiene (COSHH assessment, dust/fume/vibration/noise monitoring, face fit testing, remote monitoring), UKAS-accredited laboratory analysis (asbestos, crystalline silica, metals via ICP-AES, ion chromatography, microbiology, pharmaceuticals, PPE whole-suit testing, hazard assessment/toxicology), hospital ventilation Authorising Engineer services, and consultancy/expert witness work for occupational disease litigation. Proprietary technology assets include the IOM Inhalable Dust Sampler, the Walton-Beckett microscope eyepiece graticule (incorporated into WHO asbestos methods), the SafeNano Centre of Excellence, and the IOMLIFET exposure assessment tool.

The business model is professional services fee-for-engagement: revenues come from research contracts (HSE, EU-OSHA, WHO, NIHR), consultancy and expert witness retainers, and laboratory testing on a quote basis. Pricing is not publicly disclosed; terms specify per-proposal estimates valid 30 days, charge-out rates that include travel time, and the right to revise fees on engagements exceeding six months. The organisation operates from a headquarters and main laboratory at Pentland Science Park (Edinburgh) following a January 2026 relocation, with regional offices in Stafford and Chesterfield. Customer segments are diversified across industrial/manufacturing, healthcare and NHS trusts, construction and property management, education, legal services, and chemical/nanotechnology. Distribution is direct sales-led through a small in-house team, supported by content marketing (IOM Today blog, impact reports), conference presence, and LinkedIn activity. Accreditations include WHO Collaborating Centre status (since 1995), UKAS testing laboratory No. 0374, IHEEM Authorising Engineer, and ISO 14001:2015 — collectively a significant barrier to entry in regulated occupational health work.
