Legionella Risk Assessment

Legionnaires disease is a potentially fatal infection, caused by the inhalation of infected droplets of water from water systems contaminated with certain strains of the legionella bacterium.

At Swiftclean, we understand the requirements of a Legionella risk assessment and regularly aid companies with the Legionella assessment process to ensure an effective management tool is in place to help control risk and monitor conditions within their water system.

As one of the leading Legionella testing companies in the UK, we can help your business by identifying the factors which increase risk, so that you can see where you need to prioritise actions and what you need to do in order for your business to comply with the Legionella control regulations.

What is Legionella and What Causes It?

Legionnaires disease is a severe form of pneumonia – a lung inflammation caused by infection. The disease is contracted by breathing in mist from water that contains the bacteria.

Legionella bacteria is widespread within natural water sources such as river, lakes and reservoirs. The bacteria may also be found in purpose-built water systems such as cooling towers, hot and cold water systems and spa pools. People can contract the illness by inhaling small droplets of water in the air containing the bacteria.

Outbreaks of Legionnaires disease often occur from exposure to the Legionella bacteria growing in purpose-built water systems where poor water condition allows for the proliferation of the legionella bacteria to dangerous levels. The disease cannot be spread from person to person – only by contaminated water being inhaled.

Under the Control of Substances Hazardous to Health (COSHH) Regulations, owners and operators of all commercial premises (including: Social Housing, Facilities Management, Hotels & Stadiums, Healthcare, Education and many others) have a statutory duty to control the risk of legionella bacteria in water systems.

Swiftclean can conduct a Legionella Risk Assessment, which will identify the level of risk within your property.

What is A Legionella Risk Assessment?

A Legionella risk assessment is a tool used to identify the risk factors in a facility and determine interventions to help control the risks of Legionnaires’ disease.

Is It A Legal Requirement to Have A Legionella Risk Assessment?

There is a legal duty in place to assess and control the risk of exposure to Legionella bacteria, especially for commercial businesses, including hotels, spas, schools and social housing.
Legionella risk assessments should be reviewed at least every two years. However, there are certain situations where a review is required sooner by law. They include:

  • When a site’s population falls within the high risk category (i.e. the elderly or those with a low immune system
  • When a water system has had a change of use
  • When changes are made to a water system, pipework or assets
  • When current monitoring and management processes are no longer proving effective
  • When a Legionella outbreak is suspected, or positive samples are recorded

Legionella Risk Assessment for Landlords

Landlords are under a duty to ensure that the risk of exposure to tenants, residents and visitors to Legionella is properly assessed and controlled. Health and safety legislation requires Landlords to carry out risk assessments and maintain control measures to minimise the risk.

Property managers or individuals responsible for the control of Legionella bacteria should ensure a safe and disease-free environment. The law is clear that if you are a landlord and rent out your property (or even a room within your own home) then you have legal responsibilities to ensure that the property is kept safe from health hazards. The requirement stems from the COSHH Regulations, which require the control of substances hazardous to health, bacteria being included; Section 3(2) of the Health and Safety Work Act 1974 to make provisions for the legislation to apply to landlords of both business and domestic premises.
