Legionella Risk Assessment

Legionella Risk Assessment


Health & Safety Law is clear regarding the risk of legionella. Owners of domestic properties which are used for rental accommodation should undertake a Legionella Risk Assessment.



Why you need a Legionella Risk Assessment

  • Risk assessments are the responsibility of the statutory duty holder.
  • The duty holder or responsible party needs to consider, assess and control the risk of exposure to legionella
  • Risk assessments must be produced by a competent person to ensure compliance
  • The risk assessment will identify measures to reduce the risk of increasing levels of legionella bacteria
  • The duty holder or responsible party must inform a tenant about any control measures put in place to maintain a low risk
  • The duty holder is ultimately responsible for the consequences of not having an assessment



Legionella Risk Assessments are required on all domestic dwellings which are rented out to a tenant; Landlords have a duty of care for all tenants, visitors and any person on site


The 2014 technical guidance states what Landlords and duty holders must do to comply with the law. The size of water storage on site was reduced from 300 litres to no lower limit.

Health & Safety Guidance

“2.138 Landlords who provide residential accommodation, as the person in control of the premises or responsible for the water systems in their premises, have a legal duty to ensure that the risk of exposure of tenants to legionella is properly assessed and controlled. This duty extends to residents, guests, tenants and customers. They can carry out a risk assessment themselves if they are competent, or employ somebody who is.“ HSG274 (2014)


“2.139 Where a managing (or letting) agent is used, the management

contract should clearly specify who has responsibility for maintenance and safety checks, including managing the risk from legionella. Where there is no contract or agreement in place or it does not specify who has responsibility, the duty is placed on whoever has control of the premises and the water system in it, and in most cases, this will be the landlord themselves.“
