Cleanzyme Ltd is a UK-based environmental technology company focused on transforming how buildings manage indoor environmental quality (IEQ).

Rather than delivering traditional cleaning or facilities management services, the company is developing a platform designed to enable continuous environmental monitoring, risk detection, and compliance assurance across building portfolios.

This approach reflects a shift away from reactive, one-off interventions towards structured, evidence-led environmental management, where conditions are monitored, risks are identified early, and actions are verified over time.

As part of this model, Cleanzyme develops and introduces compliance-led environmental technologies that support real-world building challenges.

In 2026, the company secured approval from the UK Health and Safety Executive (HSE) under the Control of Pesticides Regulations (COPR) for its professional-use product Mould Pro (HSE No. 11173-GB), a surface biocide authorised for use against mould and mildew, and to help prevent regrowth on treated surfaces .

This milestone reflects over two years of regulatory development and positions Mould Pro as part of a new generation of solutions designed to operate within regulated frameworks, not outside them.

Cleanzyme’s broader vision is to bring together treatment, environmental monitoring, and compliance assurance into a single, scalable approach supporting housing providers, contractors, and building operators in maintaining safer, more stable indoor environments.
