If you have a cooling tower or an evaporative condenser within the air conditioning system, this must be registered with us.

The prime purpose of this is to identify potential areas that could give rise to spread of infectious disease e.g. legionella and to ensure preventative measures are taken to eliminate the risk of such infection arising to employees and the public.


Registration and licensing of Cooling Towers and Evaporative Condensers is free.

Legionella risk assessments

You should undertake a risk assessment regarding your cooling tower/evaporative condenser and the associated risks of Legionella under COSHH.
