    2. A Physical Tour of Your Property’s Water Systems
      Our technicians will tour your site, performing thorough inspections of the entirety of its water systems. This includes checks on the water temperature using the most up-to-date equipment.
    3. Bespoke Reporting
      Your report will be provided in PDF format, complete with a comprehensive guide of our findings and how to enact any remedial actions that we have recommended. This management regulatory compliance system is useful for gathering, keeping, analysing, and communicating Health, Safety, and Environmental compliance records whenever they are needed.

    Why You Need a Legionella Risk Assessment

    Are Legionella Risk Assessments a Legal Requirement?

    Under the terms of the Health and Safety at Work etc Act 1974, Legionella risk assessments are a legal obligation. This is owed to the severe risks associated with Legionella bacteria.

    Legionella bacteria can grow in any kind of purpose-built hot and cold water system. Small water droplets from these systems may then be infected by the bacteria. When these droplets are breathed in by an occupant of a building, there is a risk of them catching a serious disease as a result. This includes Legionnaires’ disease, a potentially fatal form of pneumonia.

    All hot and cold water systems that grow sediment, scale, or other types of bacteria have the potential to hold Legionella bacteria as well. If the water’s temperature is consistently between 20°C and 45°C, this provides the perfect conditions for the bacteria to grow and spread. Combining this with an aerosol release then elevates the risk of Legionella bacteria exposure, and therefore the risk of developing potentially fatal diseases.

    When to Get a Legionella Risk Assessment

    This legal information applies in the same way to landlords. If you are a landlord and rent out your property, or a room in your home, then you have a legal responsibility to ensure the health and safety of your tenants by keeping your property hazard-free. This includes circumstances where Legionella bacteria could be allowed to grow.

    To learn more, see the advice on Legionella and landlords’ responsibilities provided by the Health and Safety Executive.

    When to Get a Legionella Risk Assessment

    There is no circumstance that we wouldn’t recommend a Legionella risk assessment, but we would strongly suggest getting one carried out right away if:

    • There has been a change in your property’s key personnel
    • The building is new to your business or company
    • The building is being repurposed
    • The building has been unused for any amount of time
    • The building has never had testing or a risk assessment for Legionella before

    Who Can Carry Out Legionella Risk Assessments?

    Legionella risk assessments should always be carried out by a competent person, meeting the Health and Safety Executive’s Approved Code of Practice and the related technical guidance found in HSG274.

    Some businesses will provide Legionella testing kits, but we would advise caution in using these. This is because they are not as accurate as the state-of-the-art technology that services like ours use as part of the assessment and inspection.
