What is Legionnaires Disease?

Legionnaires’ Disease is a pneumonia like illness caused by the Legionella bacteria which can be fatal. The infection is caused by inhaling small droplets of water contaminated by the bacteria. The disease cannot be passed from one person to another.

The bacteria itself is found in the natural environment, and may contaminate and grow inside water systems, including domestic hot and cold water systems. They can survive low temperatures but the prime temperature they thrive at is between 20 – 45°C.

What is involved?

A survey of the property will be required to assess the risk. It involves the checking of the full water system, taking the temperature of the water at the outlets, (both ho​t and cold). Any hot or cold water tanks which may be found in the loft. We also check the outlets for any signs of limescale, the condition of them and other various points.

Do I need one?

In the simplest of terms no, because failing to comply to any part of ACOP in itself is not an offence. However that failiure to comply can be used in any criminal proceedings in court in contravention of the following; 'The Health & Safety at Work Act 1974, Control Substances Hazardous to Health (COSHH) Regulations 2002 and 'Management of Health and Safety at Work Regulations 1999.

In short, Landlords need to protect themselves.

Who is at risk?

Everyone is at risk of contracting Legionnaires Disease, however the risk increases with the following;

  • People over 45 years of age

  • Smokers and heavy drinkers

  • People suffering from chronic respiratory or kidney disease

  • Diabetes, lung and heart disease

  • Anyone with an impaired immune system
