Cooling towers and evaporative condensers


If you control non-domestic premises in County Durham, you must ensure that you notify us of any cooling tower or evaporative condenser (notifiable devices) on the premises.

You must also notify us if any device ceases to be used or if any changes are made. This is a requirement of the Notification of Cooling Towers and Evaporative Condensers Regulations 1992. 

Notification purpose

The prime purpose of the notification regime is is to enable us to identify potential areas that could give rise to spread of infectious disease such as legionella. It also ensures preventative measures are taken to eliminate the risk of such infection arising to employees and the public.

Applicable fees

No fees are payable for any notification types.

Application evaluation process

When we receive notification relating to a new device, the details will be entered onto our register of cooling towers and evaporative condensers. Where changes are notified in relation to existing devices, the register will be amended accordingly.

Implied acknowledgment of notification ('tacit consent')

We aim to acknowledge your notification and the details onto our register within 28 days of receipt. It is our usual practice to contact you within this timeframe and undertake an inspection of your notified devices. 

If you do not hear from us within 28 days, you have the legal right (known as 'tacit consent') to assume that your notification is successful. However, if you have not heard from us within 14 days of submitting your application we request that you contact us.
