Insurance for Cleaning Contractors Using Chemicals

Quick answer

Insurance for cleaning contractors using chemicals should reflect the substances used, where they are stored, how staff are trained and what premises are cleaned. Chemical-related claims can involve injury, property damage, contamination, pollution, employee illness and contract disputes, so COSHH controls and accurate insurance disclosure matter.

Why Chemical Use Changes Cleaning Contractor Risk

Many cleaning businesses use everyday products, but some contractors handle stronger degreasers, disinfectants, descalers, solvents, sanitisers, acids, alkalis, biocides or specialist industrial chemicals. Risk increases when chemicals are diluted incorrectly, mixed, stored poorly, transported between sites or used on sensitive surfaces. Client premises also matter. A chemical incident in an office may damage flooring or furniture, while an incident in healthcare, food manufacturing, industrial or education settings can raise wider contamination and safety concerns. Insurance should reflect the products used and the work undertaken rather than treating all cleaning chemicals as low-risk consumables.

• COSHH assessments for hazardous substances
• Training on dilution, PPE and safe use
• Storage and transport controls for mobile teams
• Disclosure of specialist chemicals and higher-risk premises

Liability Claims Linked To Cleaning Chemicals

Chemical-related claims can involve burns, respiratory irritation, allergic reactions, damaged surfaces, stained carpets, corroded fixtures, contaminated stock, watercourse pollution or allegations that the wrong product was used. Public liability may be relevant where a third party is injured or client property is damaged, while employers liability may respond to covered employee injury or illness claims. Some environmental or pollution incidents may need specific cover and may be excluded from standard wording. Contractors should check policy terms carefully before accepting work involving stronger substances, drains, waste, runoff, food environments or industrial premises.

• Third-party injury and client property damage
• Employee exposure, PPE and training records
• Pollution, runoff, waste and contamination concerns
• Surface damage from incorrect product selection

COSHH, RAMS And Evidence Insurers May Expect

Insurance and procurement evidence should connect chemical controls to real working practices. COSHH assessments should be current, staff should know how to read product labels and safety data sheets, and RAMS should explain how chemicals will be used on each site. Supervisors should check that products are not decanted into unlabelled containers, incompatible chemicals are not mixed and PPE is available. If a claim arises months later, training logs, product records, photographs, cleaning schedules and incident reports can help show what was used and how work was controlled. These records also help when tender teams ask for safety documentation.

• Safety data sheets and COSHH assessments
• Product-use records and site-specific RAMS
• Staff training, PPE and supervision logs
• Incident and near-miss reporting procedures

Getting Chemical Risk Reflected In The Policy

Cleaning contractors should tell their broker or insurer about specialist chemicals, industrial degreasing, healthcare sanitisation, food premises cleaning, pressure washing chemicals, biohazard work, pest-related cleaning or any work involving waste and contamination. They should also review exclusions for pollution, gradual damage, faulty workmanship, professional advice, treatment risks and work at specific premises. Insure24 can help UK cleaning contractors compare suitable cover options and consider how chemical use interacts with public liability, employers liability, equipment, vehicles, pollution and contract requirements.

• Disclose specialist substances and higher-risk cleaning methods
• Check pollution and contamination wording
• Review exclusions before accepting unusual work
• Align certificates, RAMS and contract requirements
