Adept House Logo Legionnaires' Disease Risk Assessment From £85.00
Under general health and safety law a Landlord, as a person in control of a premises, has a duty to prevent and control the risk to Tenants of exposure to the Legionella bacteria.  This is done by carrying out a risk assessment of the relevant property’s water system to identify any potential sources of the Legionella bacteria and what should be done to minimise or eliminate bacteria growth.  The person carrying out such a risk assessment should be ‘competent’ to do so and understand what is required; the assessment should also be reviewed periodically.  Tenants should also be provided with information relating to Legionnaires’ disease and what they must do during their Tenancy Period to reduce the risks of Legionella bacteria formation.

Legionnaires’ disease is the most common (and serious) disease caused by the Legionella bacteria.  The name comes from a mystery disease in 1976 affecting 221 people, of which 34 died; it was first noticed amongst attendees of an ‘American Legion’ convention leading to the bacteria being known as ‘Legionella’.  The disease is usually thought to be contracted by inhalation of airborne water particles (which occur when a tap is run or a shower is used for example) that contain the bacteria.  Legionnaires’ disease is a potentially fatal form of pneumonia to which everyone is susceptible, although certain people are at higher risk from contracting the disease.  Legionella bacteria is always present in various water sources but in low enough numbers to make it unlikely that a person would catch Legionnaires’ disease.  However, the bacteria grows and becomes a health risk when water is stored (or is stagnant) at higher temperatures.  Bacteria growth is also increased by ‘nutrients’ being available in the water system such as debris in cold water tanks, rust in pipes and limescale in pipes and on outlets.

We are able to provide Legionnaires' Disease Risk Assessments that are fully insured and audited (by Elmhurst Energy Systems Ltd.).  Following the assessment you will also be provided with a comprehensive report which not only includes relevant information and legislation, but also a certificate of compliance to show that a risk assessment has been carried out by a competent person.  We will also leave a 'Tenant Information Sheet' in the property which includes the Tenant's responsibilities regarding Legionella.

What does a Risk Assessment involve?

  • Survey of the property to create a water system schematic.

  • Examination of the cold water storage tank where accessible.

  • Taking hot and cold water temperatures at key flow points and taps.

  • Examination of the hot water storage cylinder/calorifier.

  • Checking pipe runs (inc. dead legs and blind ends), and checking shower outlets.

  • Checking for presence of thermostatic mixer valves.
