The primary method used to control the risk from Legionella is water temperature control. 
Water services should be operated at temperatures that prevent Legionella growth:

  • Hot water storage cylinders (calorifiers) should store water at 60°C or higher
  • Hot water should be distributed at 50°C or higher (thermostatic mixer valves need to be fitted as close as possible to outlets, where a scald risk is identified).
  • Cold water should be stored and distributed below 20°C.

ACOP L8 and HSG 274 state that arrangements should be in place for the regular monitoring of the hot and cold water systems within your establishment and should be carried out by person(s) with the appropriate training and expertise.
