ISS Group Services

What ISS Group Services does

ISS Group Services Ltd is a UK-based, privately held independent service organisation specialising in the maintenance and repair of scanning and transmission electron microscopes (SEMs and TEMs) and associated analytical instrumentation. Founded in 1977 by David Cunningham and headquartered in Middleton, Manchester, the company occupies a niche as one of the few manufacturer-independent service providers in the UK electron optics market, supporting both modern and legacy instruments from major OEMs including FEI/Thermo Fisher, JEOL, and Philips. Its service portfolio spans bespoke annual maintenance contracts, on-demand repair work, a sizeable spare parts inventory for older microscope models, a pre-owned equipment resale business, and bespoke operator training for SEM and TEM users.

The company's technical foundation rests on a small, highly experienced engineering team — collectively holding 75 years of TEM experience — supplemented by an in-house workshop with electronics capability that enables cost-effective component-level repairs. ISS operates a direct field sales model, with Field Service Engineers deployed onsite at customer laboratories and a Middleton-based office team coordinating quotations, service scheduling, and parts logistics. Revenue is generated across five streams: recurring subscription-style service contracts, transactional on-demand servicing, one-time new and pre-owned equipment sales, spare parts hardware sales, and professional-services training. Distribution partnerships with EMSIS (German TEM camera manufacturer) and Kammrath & Weiss (EM accessories) extend its new-product catalogue.

ISS is privately held with no institutional funding, no parent company, and no subsidiaries. Its customer base spans UK research and academic laboratories alongside industrial EM users, with no public disclosure of named customer accounts, revenue figures, or headcount trend data. The firm has operated continuously for over 45 years under founder-team leadership (Simon McGaw, formerly of the 1998-acquired Electron Optical Services, now serves as Managing Director), suggesting a stable, cash-generative, and geographically contained business rather than a venture-backed growth vehicle.
