Public health - cooling tower notification

EUGO logo

If you control non-domestic premises you must notify the local authority of any cooling tower or evaporative condenser (notifiable devices) on the premises.

We need to know about cooling towers because legionella pneumophila bacterium (legionellosis) can be found in many recirculators and water supply systems. Notification helps inspectors to investigate legionella outbreaks.

You must notify us in writing (including by electronic means) on a form approved by the Health and Safety Executive. You must also tell us about any changes to the notification information within one month of the change, in writing.

If the device ceases to be a notifiable device you must let us know in writing as soon as possible.

There is no charge for notification.

What the law says

The Notification of Cooling Towers and Evaporative Condenser Regulations 1992 require notification of wet cooling towers and evaporative condensers to local authorities in whose area the equipment is situated. This is regardless of whether the local authority or Health and Safety (Executive) is the enforcing authority.

The regulations also require notification to the local authority of the closure of the device.

How long will my notification take to process?

We aim to process your notification as soon as possible. We will confirm that we have received your notification. Please contact us if you have any queries.

Complaints about cooling towers

Initially, please try contacting the owner of the cooling tower preferably in the form of a letter (with proof of delivery). If that doesn't work please contact us.
