If you run a cleaning business, whether it’s a larger organisation or a domestic service with a small team, managing multiple commercial sites, you’ve probably come across the term COSHH. But what exactly does it mean, and why is it so critical to your business?

COSHH stands for the Control of Substances Hazardous to Health. It’s a set of UK regulations designed to protect workers from health risks linked to hazardous substances in the workplace. And for cleaning professionals, this matters more than it does for most other workers.

Every day, cleaners work with powerful products like bleach, descalers, disinfectants and solvents. They carry potential health risks. Without proper handling and controls in place, those risks can lead to serious injury, illness, or even long-term health conditions. That’s where COSHH comes in.

What Does COSHH Cover and Why It Matters

COSHH is not a simple tick-box exercise. It requires employers to assess the risks posed by hazardous substances and take appropriate steps to reduce or eliminate them. For cleaning businesses, this means:

• Identifying which chemicals and products you use that may pose health risks
• Evaluating how workers may be exposed to those substances (through skin contact, inhalation, etc.)
• Putting controls in place to minimise those risks—such as protective equipment or safer handling procedures
• Providing information and training to employees
• Having proper COSHH risk assessments and Safety Data Sheets (SDS) on hand

And importantly, COSHH applies to all cleaning companies, regardless of size. Even if your team is small, you’re still legally required to protect your workers.

Why COSHH Is Non-Negotiable in Cleaning

Many cleaning business owners don’t realise just how many everyday products are considered hazardous under COSHH. Take bleach, for example—commonly used in both home and office cleaning. If mixed incorrectly, or used in poorly ventilated areas, it can release toxic fumes that cause serious harm.

In fact, some of the most common risks for cleaners include:

• Skin irritation and burns from direct contact with strong cleaning agents
• Respiratory issues caused by inhaling fumes from sprays and solutions
• Eye damage if corrosive substances are splashed
• Long-term health effects, such as asthma or dermatitis from repeated exposure

That’s why COSHH isn’t just one documentation piece that helps you stay compliant. In fact, it’s about protecting your team and building a safer business.

The Cost of COSHH Non-Compliance

Failing to follow COSHH regulations can lead to far more than internal headaches. If an employee becomes unwell due to unsafe chemical handling, your business could face:

• Enforcement action or fines from the HSE
• Legal claims and compensation cases 
• Reputation damage—especially in larger contracts that demand strong compliance practices
• Increased insurance premiums 

Many public bodies and corporate clients now require evidence of COSHH compliance before awarding contracts. Without it, you may find yourself locked out of bigger opportunities.

How to Make COSHH Work for Your Business

The good news? COSHH compliance doesn’t have to be complicated.

Start by keeping a central register of the substances you use and making sure each product has an up-to-date Safety Data Sheet. You should also ensure COSHH risk assessments are completed for each hazardous substance—this includes information on safe use, PPE requirements, and emergency procedures.

Then, make sure your team is properly trained. This isn’t just about handing them a manual—it’s about explaining the real-life risks in plain language, showing them what to look out for, and giving them the tools to stay safe. Regular refresher training is key, especially as products or team members change.
