Frequently Asked Questions

  • If you are a dutyholder (e.g. landlord, employer, or facilities manager), you are legally required under ACoP L8 and the Health and Safety at Work Act to assess and manage the risk of Legionella. Testing may be required regularly if you operate a water system where there's a foreseeable risk, especially in healthcare, hospitality, leisure, or education settings.

  • Typically, tanks should be inspected annually and cleaned/disinfected at least every 12 months, or sooner if contamination, stagnation or poor water quality is identified.
