How can I prevent Legionnaires' disease in my home or business?

Top tips to avoid problems with Legionnaires' disease include:

  • Only use a qualified plumber
  • Ensure suitable fittings are used (WRAS-approved)
  • Keep the design of plumbing systems simple
  • Design a system so water is regularly turned over and does not stagnate
  • Ensure hot and cold water are kept at the correct temperatures
  • Businesses should follow the advice within the HSE approved code of practice L8 to ensure they meet their legal duties under the Health and Safety at Work Act 1974 to manage risks from legionella bacteria.

Covid-19 Update:

In May 2020, Water UK published guidance to building owners, landlords and managers on recovering buildings and networks after prolonged inactivity during Covid-19 to avoid risks of adverse water quality and potential risks to health – including legionella bacteria.
