What Guardtech Cleanrooms does

Guardtech Cleanrooms Ltd, founded in 2000 and headquartered in Haverhill, Suffolk, is a privately-held UK specialist in the design, construction and installation of modular cleanrooms and controlled environments. The company operates as part of the broader 'Guardtech Group' umbrella alongside five distinct brands: Cleanroom Solutions (large-scale turnkey facilities), Cleancube (portable shipping-container cleanrooms), Isopod (rapid-assembly stainless-steel pod systems), Isoblok (pre-fabricated steel portal frame modules) and Guardware (cleanroom furniture and equipment). It also runs Guardtech Nordic AB for Scandinavian distribution. Core technology centres on modular construction, HEPA filtration, advanced HVAC, and ISO 14644 / EU GMP-compliant environmental monitoring, with niche capability in ultra-low dewpoint (-80°C) dry rooms delivered through partnerships with Dry Air Ltd and DryR.

The business serves three primary end markets: Life Sciences (pharmaceutical, biotech, cell and gene therapy), Healthcare (NHS aseptic pharmacies, clinical laboratories), and High-Tech Engineering (semiconductor, micro-electronics, battery manufacturing, aerospace). Customers include AstraZeneca, BAE Systems, KLA, Cytiva, Oxford Quantum Circuits, NHS Trusts, Northumbria University and BDD Pharma, with 9 concurrent international projects spanning Europe and Africa. Revenue is generated through a mix of one-time project-based cleanroom construction, recurring aftercare service plans (1/3/5-year PPM and validation contracts), professional decontamination services, and hardware sales through the Guardware brand, with quote-based pricing and online Isopod/CleanCube configurators supporting a regionalised direct sales team.

The firm remains a family business led by founder Ray Wheeler and Managing Director Mark Wheeler, with Projects Director Conor Barwise, and is self-funded with no disclosed institutional investment. In 2025 it reported a record 40 projects and record turnover, expanded manufacturing into Thetford, Norfolk, and consolidated its brands under a unified 'Guardtech' identity.
