Legionella Risk Assessments

Under the Health and Safety at Work Act 1974 and The Control of Substances Hazardous to Health Regulations 2002 (COSHH), all employers, business owners and managers of buildings are legally required to carry out Legionella Risk Assessments (LRAs).

Legionella Risk Assessments will help employers, business owners and managers of buildings identify and assess potential sources of exposure to Legionella in the workplace so that action can be taken to prevent or control any risks found and that such risks are suitably managed through regular, proper maintenance.

Maximum Climate Control’s team of Legionella experts are ready at short notice no matter the size of the job. We operate from Hampshire and offer a range of Legionella Risk Assessments for both commercial and domestic properties up and down the UK – if you would like to know more about our risk assessments or receive a no obligation quotation, simply get in touch with our Service Team.

What is Legionella’s Disease?

Legionnaires’ Disease is a severe form of pneumonia caused by the Legionella bacterium. It is a potentially deadly form of pneumonia that can affect anyone, but mainly affects those who are over the age of 50 and have other health problems or a weakened immune system.

Legionella FAQs

Legionella disease is a topic that has a lot of questions regarding the safety and law, which is why we’ve broken down some frequently asked questions, so that you have a comprehensive understanding of what to expect when dealing with Legionella bacteria in your property.

What are the symptoms of Legionella?

Symptoms of Legionnaires’ Disease include fever, cough, muscle aches, chest pain and shortness of breath. If left untreated, Legionnaires’ Disease can be fatal.

When is a Legionella Risk Assessment required?

The Approved Code of Practice (ACOP) L8 (4th edition) suggests that Legionella Risk Assessments should be reviewed regularly.

Typically, this advised that the frequency should be every two years. However, the suggestion is now that this should be undertaken more frequently or “when there is reason to suspect that it is no longer valid” such as when occupancy levels change, when there is a change in use of the building or when there is an update in legislation for example.

What is involved in a Legionella Risk Assessment?

Firstly, a review of your current records and assessments will be undertaken to check that all previous recommendations have been acted on. We will then tour the site to physically look at where water is stored and where there is potential for aerosols to be formed. In addition, there will be a review of the current risk control measures that are in place to ensure they are fit for purpose with hot and cold water temperatures being recorded where relevant to ensure compliance with regulations.

Based on these findings, a report will be produced that will document Management responsibilities and any recommendations for action that should be undertaken to lessen or lower the Legionella risk such as water sampling and testing, pipework insulation, supplementary, disinfection, etc.

Choosing a trusted assessor

If you have limited familiarity with Legionella, it is essential to collaborate with skilled professionals who specialise in similar bacteria. The individuals and advisors you choose should hold proper accreditation or certification, adhere to established guidelines for optimal practices, and comply with laws and regulations.

Competent Legionella Risk Assessors should possess a thorough understanding of the risks associated with the bacteria, receive training, possess relevant experience, and implement an effective plan for mitigating its risks.
