You have a positive Legionella sample
A laboratory has reported Legionella in your water. What happens next depends on the count and how many outlets it shows up at. Work through the immediate steps, then investigate the cause.
An outlet failed its temperature check
A sentinel or representative outlet missed its target (hot below 50 °C, or cold above 20 °C). Confirm it is real, find the cause, correct it, and record it. An untracked drift is exactly what enforcement looks for.
You are facing an HSE inspection
An inspector wants to see that you have assessed the risk, put controls in place, and can prove both with records. Here is what they look for and how to be ready.
You are the new Responsible Person
You have inherited the Legionella duty. Before anything else, find out what exists, what is missing, and who does what. This is the orderly way to take it over.
Getting a care home Legionella-compliant
Care homes serve people who are far more vulnerable to infection, so water safety carries extra weight, including scald-safe temperatures and HTM 04-01 thinking. Here is what to get right.
Auditing water safety in a hotel
Hotels combine high-risk features (little-used guest rooms, spa pools, large hot water systems) with a reputation that one case can damage. Here is how to audit it properly.
Understanding landlord Legionella duties
Landlords must assess and control Legionella risk in rented homes, but most domestic systems are low risk if water is used regularly. Here is what is genuinely required, and what is not.
