The Notification of Cooling Towers and Evaporative Condensers Regulations 1992.

The purpose of the regulations is to ensure the local authority is informed of the location of relevant devices.

It is the duty of any person having, to any extent, control of a premise, not to allow the installation or use of a notifiable device unless Cornwall Council is informed by completion of the form above. If there are any changes in circumstances, such as the device no longer being used or change of ownership, the Council must be notified within one month.

There are no criteria that prevent anyone who operates a cooling tower or evaporating condenser from registering.

Over recent years there have been a number of outbreaks of Legionnaires' Disease associated with cooling systems (cooling towers and evaporative condensers), which have often resulted in serious cases of infection and fatalities in about 12% of cases.

Such outbreaks also 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 Control of Substances Hazardous to Health Regulations and Approved Code of Practice on the prevention and / or control of legionellosis, give rise to the potential conditions in which outbreaks can and do occur.

Due to the risk posed by wet cooling systems if not properly maintained, these regulations were brought into being in 1992. The regulations require the notification of cooling towers and evaporative condensers to the appropriate local authority.

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.

Whilst the task of maintaining records of wet cooling systems under the regulations rests with Local Authorities, and in this particular case Cornwall Council, responsibility for enforcement in respect of standards of assessment and control is split between the Health and Safety Executive (HSE) and Cornwall Council, depending on the main activity of the premise.

Operators of installations should be aware that both Cornwall Council and the HSE will undertake a number of visits to their premises to ensure standards are met and will take enforcement action where appropriate.

Details of the location of notifiable devices are kept on a public register which is held by the council.  Please contact us on 0300 1234 212 or email to access details held on the register.

If you have any complaints or concerns about the service you have received or the information provided, then please do not hesitate to contact us on 0300 1234 212 and ask to speak to an officer from the Public Protection team who will deal with your enquiry, alternatively you can email your concerns to
