By law, a business with a cooling tower or evaporative condenser has to register with us.

The main purpose of the register is to allow us to identify where potential sources or risk are (such as outbreaks of legionnaires' disease), and allow us to monitor and inspect them more easily.

You should complete the registration form (below) and submit it to On request, we can post a form out to you and you can post it back to us.

The name and address of the company applying to register the cooling tower will be required along with the number of cooling towers to be registered.

There is no cost to register.

Cooling towers notification form

On receipt of the application form we will enter the cooling tower(s) details onto a public register.

You must also let us know of any changes to the system, or if it's no longer in operation.
