Legionella Risk Assessment

A Legionella risk assessment checks water systems for bacteria that can cause Legionnaires' disease. It helps find risks, assess dangers, and put safety measures in place. Regular testing keeps water clean, prevents health issues, and ensures legal compliance.

Why is a Legionella Risk Assessment Important?

Protect Your Business with a Legionella Risk Assessment

Legionella bacteria grow in water systems like cooling towers, water tanks, showers, spa pools, and air conditioning units. If people breathe in tiny water droplets with Legionella, they can develop Legionnaires' disease, a serious lung infection.

UK laws, such as the Health and Safety at Work Act 1974, require businesses, landlords, and property owners to manage Legionella risks. The Control of Substances Hazardous to Health Regulations 2002 (COSHH) and HSE's Approved Code of Practice (L8) also provide legal guidance. Businesses must carry out annual risk assessments to ensure water systems remain safe.

Without regular checks, Legionella bacteria can multiply in stagnant or dirty water, increasing the risk of outbreaks. Property owners and managers must take action to protect people from harm.

Legionnaires' disease is preventable with proper monitoring and maintenance. A risk assessment helps businesses follow UK health and safety laws while keeping employees, customers, and residents safe.

How to Keep Water Safe

Preventing Legionella

To prevent Legionella growth, businesses should:

  • Flush Unused Outlets: Regularly run taps and showers to clear stagnant water.
  • Monitor Water Temperature: Keep cold water below 20°C and hot water above 50°C.
  • Clean & Disinfect Systems: Regularly remove dirt, limescale, and bacteria build-up.
  • Reduce Water Storage Time: Prevent water from sitting unused for long periods.
  • Use Legionella Filters: Install filters in high-risk areas to remove bacteria.
  • Maintain Records: Keep logs of inspections, cleaning schedules, and risk assessments.
  • Use Chemical Treatments: Introduce safe disinfectants to kill bacteria.
  • Install Remote Water Monitoring: Use technology to track temperature changes and water movement.

Good contact to say when they would arrive on site with information up front on what they would need to complete the risk assessments. Once received the risk assessments were easy to read and the 'to do' tasks were explained to ensure we remained compliant. Very competitively priced as well. Highly recommend.

Fantastic service - contacted last minute on Tuesday as needed some risk assessments carried out by today (Friday) for a regulatory inspection. Max arranged for an assessor to come to site this morning, first thing before the building got busy with staff and patients (we are an NHS premises). The assessor was polite, friendly, professional and helpful with useful suggestions. We were on a really tight deadline and the risk assessment reports were sent over well within the deadline, they look professional and thorough and only a couple of actions were highlighted (which we have already carried out). I have already recommended HSRA to several of my peers. Thank you

Using HSRA to do our Fire Risk Assessment was simple, we sent our address and within an hour we had a quote once their team checked the site on google maps. An Appointment was made for their surveyor to arrive and inspect the property. The Report arrived a couple of days later with a information for every part of the business including guidance on what to do in those areas that were not up to scratch. A big thanks to Max and his team at HSRA
