Legionella control across the UK
Legionella risk assessments and water hygiene for commercial buildings
We assess your water system and set out clear controls. Then we do the engineer work that keeps it safe. We only recommend what your building actually needs.
Services
Everything your water system needs to stay compliant
From the first risk assessment to the engineer tasks your written scheme calls for. One supplier and one set of records.
Legionella risk assessment
A full survey of your hot and cold water system to L8 and HSG274. You get a written scheme of control and a clear action list.
Risk assessmentsWater monitoring
Monthly temperature checks at sentinel outlets and flushing of little used outlets. Every visit is logged with a written report.
MonitoringWater sampling and testing
Laboratory testing for legionella where your assessment or monitoring shows a reason. We will tell you when sampling is not needed.
SamplingTank cleaning and disinfection
Inspection of cold water storage tanks with cleaning and disinfection when the inspection shows it is due.
Tank cleaningTMV servicing
Annual service and fail safe testing of thermostatic mixing valves. Essential wherever vulnerable people use hot water.
TMV servicingRemedial works
Dead leg removal and expansion vessel work. Also calorifier inspection and showerhead descaling. Done by qualified engineers.
Remedial worksWhat the law asks of you
The duty is simple. Doing it properly is the hard part.
If you control a building with a water system you must assess the legionella risk and control it. The duty comes from:
- The Health and Safety at Work etc. Act 1974
- The Management of Health and Safety at Work Regulations 1999
- The Control of Substances Hazardous to Health Regulations 2002
HSE explains how to meet it in the Approved Code of Practice L8. The technical detail sits in HSG274. Temperature is the main control for most hot and cold water systems.
“An assessment tells you what the system looks like.”
That is why we start with the assessment. It shows where water sits still and where temperatures drift. It also shows who could be at risk. Everything else we recommend follows from what it finds.
Sampling has its place. It belongs where the assessment or the checks give a reason for it. It is not a standing monthly charge.
Testing or assessment: which do you need?How it works
From first visit to a scheme that runs itself
Survey
We visit and map your water system. You get a fixed quote for the site.
Assess
Your risk assessment and written scheme of control. It names who does what and how often.
Control
Your team runs the simple checks or we do them for you. Our engineers handle the rest.
Review
We review the assessment when your building or its use changes. Your records stay in one place.
Sectors
Built for commercial and managed buildings
Single sites and multi site estates. We work with facilities managers and operations teams.

Common questions
Is a legionella risk assessment a legal requirement?
Yes. If you control premises with a water system you must assess the risk from legionella and put controls in place. The duty comes from the Health and Safety at Work etc. Act 1974 and the COSHH Regulations 2002. HSE's Approved Code of Practice L8 sets out how to meet it.
Is there such a thing as a legionella certificate?
No. The law asks for a risk assessment and records that show your controls are working. A certificate on its own proves nothing. Be wary of anyone selling one.
How often should a legionella risk assessment be reviewed?
There is no fixed legal interval. Review it whenever the water system changes or the building is used differently. Review it if your checks show the controls are not working. Many sites review every two years.
Do you cover my area?
We work with commercial sites across the UK. Tell us where your buildings are when you request a survey and we will confirm the visit date.
