What occurs during a cleaning and disinfection?

Clean and disinfection services are provided in accordance with ACoP L8 and in compliance with the processes described in BS855468:2015.

  • An engineer will come to your site and conduct an initial evaluation to see whether any extra health and safety precautions are necessary.
  • The cold water storage tank and associated pump sets must be isolated.
  • Drain the tank completely and do a physical clean to perfect aesthetic standards.
