Water hygiene training courses are essential for ensuring safety, regulatory compliance, and operational efficiency within the UK water industry. Our courses provide all the required knowledge and awareness of good water hygiene practices, including the control of legionella bacteria and prevention of disease potential contamination.
Delivered through our specialist division, HX Training, these national water hygiene training courses are developed by experienced water industry professionals and fully aligned with best practices and legislation, including ACOP L8, HSG274, the Health and Safety at Work Act 1974, and the Control of Substances Hazardous to Health Regulations 2002.
Our training supports a wide range of professionals and industries, including water company employees, water company subcontractors, and self lay organisations (SLOs). Whether you’re responsible for cooling systems, closed systems, or filtration at operational sites such as water pumping stations, water treatment works, or service reservoirs, we’ve developed flexible learning formats including e-learning, e-classroom, and face-to-face delivery, all designed to meet your needs.
Our accredited water hygiene training courses help you understand your legal responsibilities while gaining practical, real-world skills to maintain clean water sites and protect public health. Courses combine theoretical knowledge with hands-on exercises and industry-specific scenarios to ensure your learning is relevant and immediately applicable.
