Our service includes on-site sampling and full laboratory analysis by UKAS-accredited labs, helping you stay compliant and protect occupants from Legionnaires’ disease.
What Is Legionella Water Testing?
Legionella water testing involves taking water samples from your taps, tanks, or other outlets and analysing them in a UKAS-accredited laboratory.
This test checks for the presence of Legionella pneumophila, the bacteria responsible for Legionnaires’ disease.
It’s not the same as a Legionella risk assessment, but often used alongside one—especially in higher-risk or complex systems.

Why Legionella Water Testing Matters
Paragraph:
Testing your water system is essential when:
There’s a need to confirm control measures are working
A building has been vacant or underused
There are vulnerable occupants (e.g. elderly, tenants with health conditions)
You operate in higher-risk sectors like healthcare, hospitality, or housing
Your risk assessment indicates potential exposure
When Should You Test for Legionella?
Water testing is recommended in the following situations:
If your Legionella risk assessment identifies high or uncertain risk
After periods of water system inactivity (e.g. office or rental vacancy)
When monitoring control measures
Following any system changes, refurbishments, or confirmed Legionella case
We recommend testing at regular intervals if you operate in healthcare, care homes, hospitality, or housing sectors.
What Our Doncaster Water Testing Service Includes
Our testing process involves:
- Collecting water samples from key outlets
- Laboratory analysis to detect the presence of Legionella bacteria
- A written report outlining the results
- Clear guidance if remedial action is needed
All testing is performed to HSE ACoP L8 and BS 7592:2022 standards.
How Often Should You Test?
While risk assessments are often done every two years, water testing frequency varies.
Some sites need routine testing every 3–12 months depending on system complexity, occupancy type, or compliance requirements.
We’ll advise you based on your specific situation.
