The cost of a COSHH (Control of Substances Hazardous to Health) assessment can vary depending on several factors, including the complexity of the workplace, the number of hazardous substances involved, and whether you hire an external consultant or conduct the assessment in-house.If you’re conducting the assessment internally, the main cost would be the time and resources required to identify hazardous substances, assess the risks, implement control measures, and train employees. However, if you opt to hire an external consultant, the cost can range from a few hundred to several thousand dollars, depending on the size and complexity of your organization.It’s important to remember that while there may be upfront costs associated with conducting COSHH assessments, the investment is crucial for ensuring the health and safety of employees and complying with regulatory requirements.
