What is Legionella testing, and when is it needed?
Legionella testing means taking water samples from chosen points in a building and sending them to a UKAS-accredited laboratory. It gives you documented evidence of whether your controls are working, and can show problems that temperature checks miss. We sample to BS 7592 and the guidance in HSG274, supporting ACoP L8.
There is no single frequency for sampling. Your risk assessment says whether it is needed and how often. For the full detail, see our UKAS Water Sampling page.
- The site is higher risk, such as a hospital, care home or leisure facility
- Temperature or flushing checks have failed
- Cleaning, disinfection or remedial works have just been done
- A previous result was positive
- The building has been empty and is being brought back into use
- Your risk assessment recommends it
Water sampling in York
Yorkshire Water supplies the area. Hotels and attractions with quiet rooms and seasonal use are where sampling gives the most useful evidence.
We take samples at:
- Hotels, guest houses and serviced apartments for visitors

- University and college buildings and student accommodation
- Restaurants, bars, visitor attractions and venues
- Care homes and the hospital
How sampling works
- We agree the sampling points with you, based on your risk assessment.
- Our engineer takes the samples using a set method and records the temperature, location and time at each point.
- Samples go to a UKAS-accredited laboratory in suitable conditions.
- You receive a written report with the findings, explained in plain English.
- If anything is found, we recommend the next step and arrange re-sampling to confirm the system is clear.

Questions we are asked in York
Our building is listed. Can remedial works still be done?
Often, yes. We recommend controls that are practical in the building and tell you where consent may be needed.
What do the results mean?
No Legionella detected: your controls are probably working. Carry on with routine monitoring, flushing and maintenance. Low levels detected: this should trigger a review of temperatures, water movement and use. Cleaning, flushing or small adjustments often bring the system back under control. High levels detected: this needs prompt action, which may include restricting outlets, disinfecting part of the system and investigating the cause.
