Legionella Risk Assessments
A new system, changed use, incomplete records or uncertainty about current controls can justify an assessment or review. Describe when the issue started and any change in use, operation or layout. A clear history helps distinguish a new fault from an existing limitation or a planned improvement.
Discuss your requirementsDefined services, clearly scoped.
Overview
For an estate instruction, list affected sites separately. One recurring symptom can have different causes on different installations, so retain the local history and restrictions.
What the work can include
Identify relevant water systems; consider how they operate; review exposure routes and existing controls; document findings and an action plan. The agreed scope should state which areas or equipment are included, what is excluded and the form of the completion record.
Use asset or location references that can be matched to your existing records. This makes the findings useful for budget decisions, repeat work and subsequent inspections.
Important decisions
Sampling is not a substitute for understanding the system and managing risk. The assessment should explain the basis for any monitoring or sampling recommendation.
Assessment and preparation
Provide water schematics, outlet information, temperature and flushing records and details of rarely used areas.
Name the site contact, technical approver and person who will receive the action list. Identify permit, shutdown and contractor coordination requirements before arranging attendance.
How the work proceeds
Inspect the relevant system, discuss operation with the responsible contact and identify priority improvements and control responsibilities.
Where the work forms part of a wider programme, agree the order of sites and the route for escalating material findings. Keep partial completion visible rather than closing a whole site while actions remain open.
Cost, timing and disruption
System complexity, number of outlets, inaccessible areas and missing drawings influence cost. The enquiry and available records establish what can be priced directly and what needs a site assessment first.
A coordinated programme can group suitable tasks, but access windows and operational dependencies still need to be checked for each building. Agree how additional findings will be reported and priced.
Applications across sectors
Laboratories and industrial premises may have process-specific substances and equipment. Managing agents need clear landlord and occupier interfaces; education and care premises require coordination around vulnerable users. Duties and controls should follow the actual setting. Browse the full sector range and describe the actual building use when enquiring.
Frequently asked questions
Does a satisfactory sample mean no further controls are needed?
No. A result relates to the sampled water and time; ongoing system controls still matter.
What information should I send about legionella risk assessments?
Provide water schematics, outlet information, temperature and flushing records and details of rarely used areas. Include the location and the decision you need to make, such as investigating a fault, planning a repair or setting up a programme.
What affects the price and programme?
System complexity, number of outlets, inaccessible areas and missing drawings influence cost. Any further investigation or additional work should have a clear scope before it is authorised.
What should the completion information explain?
It should identify the equipment or areas covered, the work and checks performed, limitations and unresolved actions. Match the records to your site and asset references so the next inspection or maintenance visit can use them.
