We cover all of Greater Manchester from our Leeds base, including Bolton, Stockport, Salford, Trafford, Wigan and Bury. If you run care homes, schools or a portfolio of units there, sampling gives you evidence that your water systems are under control.
Water Hygiene Services is an independent Legionella control company based in Leeds. We take water samples for estates, facilities and property managers across Greater Manchester, analysed by a UKAS-accredited laboratory. For the city centre, see our Manchester pages.

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 across Greater Manchester
United Utilities supplies the area. Multi-let commercial units with shared water systems, and sites with a lot of storage or little-used outlets, are where sampling is most useful.
We take samples at:
- Industrial estates and business parks, including large multi-unit sites where one landlord is responsible for shared water systems
- Retail parks, shopping centres and leisure complexes
- Care homes and nursing homes in the suburbs and the towns around the city
- Schools, academies and trusts with several sites in one borough
- Council and housing association stock, including sheltered housing and blocks with communal plant
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 Greater Manchester
Who is responsible for a shared commercial unit with a single water supply?
The duty usually sits with whoever controls the premises. For a multi-let building that is normally the landlord or managing agent, but it depends on the lease. We sample and report on the shared systems clearly.
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.
