Is legionella testing a legal requirement?

Legionella must be effectively controlled within all building water systems. The risk assessment will highlight areas of potential danger and advise on measures to reduce bacteria levels. Legionella bacteria is preventable, Apardion can carry out regular servicing and risk assessments to keep it under control. Business’ who fail to carry out sufficient control measures can face serious penalties.

Legionnaires Risk Assessment

A legionnaires test is the most effective way to reduce the risk of employees coming into contact with Legionella bacteria. Property managers are legally obligated to arrange for regular risk assessments to take place.

The legionella risk assessment can depend on each individual premises. Larger properties tend to have more complex water systems. Also, industries which operate using large amounts of water are at a greater risk of legionella bacteria coming into contact with their workers and employees. These include:

  • Gyms, spas & pools
  • Hotels & Hospitality
  • Catering
  • Car washes
  • Sports facilities with sprinkler systems

Our experienced professionals are able to carry out thorough legionella risk assessments, at commercial properties big or small, no matter the industry.

Routine Legionnaires Testing

Commercial legionella risk assessments can often be overlooked by landlords, however, it is their legal obligation to keep their employees safe. Apardion can provide regular legionella testing for your premises.


Most commercial properties require a legionella risk assessment every 24 months, however, this can depend on the industry also. Legally, a risk assessment may also need to be carried out if:


  • Moderations are made to a water system
