Maintaining a clean, hygienic office environment is essential for employee health, safety, and productivity. However, behind every routine cleaning service lies a critical regulatory framework: COSHH (Control of Substances Hazardous to Health).
For office managers and facilities leaders, understanding COSHH is not just about health and safety compliance, it is a vital component of vetting and managing your commercial cleaning contract.
What Is COSHH?
COSHH refers to the Control of Substances Hazardous to Health Regulations 2002, a UK statutory framework requiring employers and service providers to control substances that can cause ill health or injury.
In a commercial office setting, hazardous substances are not limited to heavy industrial chemicals. Everyday commercial cleaning materials can pose health risks if handled incorrectly, including:
- Disinfectants and Bleaches - Strong chemical formulations that can cause skin irritation, eye damage, or respiratory issues.
- Floor Cleaners and Strippers -Heavy-duty solvents capable of releasing dangerous volatile organic compounds (VOCs).
- Descalers and Toilet Cleaners - Acidic solutions that can cause chemical burns or toxic fumes if mixed with chlorine-based products.
- Aerosols and Air Fresheners - Pressurized canisters that can cause allergic reactions or present flammability hazards.
Why COSHH Matters for Your Cleaning Contract
When you outsource commercial cleaning, statutory responsibility for health and safety is shared. While your cleaning provider must protect their operatives, you retain a duty of care to ensure contractors operate safely inside your premises.
Here is what COSHH requires within a professional office cleaning contract:
- Site-Specific Risk Assessments - Prior to starting work, your cleaning provider must complete a comprehensive COSHH risk assessment tailored to your office layout, ventilation systems, and specific cleaning tasks.
- Safety Data Sheets (SDS) - Up-to-date Safety Data Sheets must be accessible on-site for every chemical product stored or used in your building. These documents detail chemical composition, storage requirements, handling precautions, and first-aid measures.
- Control Measures and Substitution - Regulations dictate that hazardous substances should be substituted with safer, eco-friendly alternatives wherever possible (such as replacing harsh solvents with microfibre technology or pH-neutral green products).
Requirements in Your Cleaning Agreement
To protect your staff, visitors, and business reputation, ensure your cleaning contract explicitly covers the following COSHH compliance measures:
- Staff Training & Certification - Verify that all cleaning personnel receive rigorous, ongoing COSHH training covering proper dilution techniques, safe handling, and chemical storage protocols.
- Correct Personal Protective Equipment (PPE) - Contractors must provide their operatives with appropriate PPE (such as chemical-resistant gloves, eye protection, and aprons) specified in the product’s Safety Data Sheet.
- Safe Storage & Labeling - Cleaning products stored on-site must remain in original, clearly labeled containers inside locked janitorial cupboards. Decanting chemicals into unlabeled spray bottles violates COSHH regulations.
- Color-Coded Equipment Protocols - Professional contractors enforce strict color-coding systems (e.g., BICSc standards) to prevent cross-contamination and ensure specific chemicals are restricted to designated zones (such as washrooms versus office desks).
Emergency Response and Auditing
Even with strict controls, chemical spills or exposure incidents can occur. Your commercial cleaning agreement should clearly define emergency response procedures, including clear reporting channels, on-site eye-wash stations, and accessible spill kits.
Regular joint safety audits between your facilities manager and the cleaning account representative ensure COSHH files remain updated and storage areas remain compliant over the lifespan of the contract.
Conclusion
COSHH compliance is a clear indicator of a professional, responsible commercial cleaning provider. By ensuring your cleaning contract mandates detailed COSHH risk assessments, trained personnel, and safe chemical management, you protect your workplace, reduce liability, and maintain a safe, healthy environment for everyone in your office.
