Cooling tower and evaporative condenser notification

If you control non-domestic premises you must ensure that you notify the council of any cooling tower or evaporative condenser on the premises.

Notification summary 

  • Notification must be in writing (including by electronic means if notifying online) on a form approved by the Health and Safety Executive.
  • You must notify us of any changes to the notification information within one month of the change, in writing or via the online facility.
  • If the device ceases to be a notifiable device eg it becomes redundant or is dismantled, you must notify us as soon as possible so the register can be updated.

Regulation summary

The main purpose of the The Notification of Cooling Towers and Evaporative Condensers Regulations 1992 (opens in a new window) is to help in the investigation of Legionnaires' disease. The regulations place a duty on the person in control of non-domestic premises to ensure that no notifiable device is situated on the premises unless the local authority has been notified in writing with details of the 'notifiable device'.

Why is there a requirement to notify?

Cooling towers and evaporative condensers have been associated with outbreaks of Legionnaires' disease caused by the bacterium Legionella pneumophila commonly found in the environment. Such outbreaks give rise to considerable public concern and take up significant enforcing authority resources. It has frequently been found that poor maintenance of such plants and poor compliance with the requirements of the following give rise to the potential conditions in which outbreaks can and do occur.

Problems can arise when the equipment is not properly managed. Optimum temperatures for growth of the bacteria are between 20°C and 45°C. Nutrients such as algae, rust and sludge that build up in the equipment can promote the rapid growth in numbers of these bacteria that can then be spread in small droplets of water and affect anybody, but which principally affects those who are susceptible because of age, illness, immunosuppression, smoking, etc.

The principle purpose for this notification process is to identify where potential sources of risk are located and allow for easier identification, monitoring and inspection by the enforcing authorities.

If that has not worked, if you are located in the UK, Citizens Advice consumer service will give you advice. From outside the UK contact the UK European Consumer Centre.
