What information is needed for an accurate Legionnaires’ risk assessment quote?

An accurate Legionnaires’ risk assessment quote depends on more than the size or general use of a site. The assessor also needs to understand the assessment boundary, the complexity of the water services, the condition and management of the systems, and the level of reporting required. Providing this information at the quotation stage helps distinguish a properly scoped assessment from a provisional price based on limited assumptions.

Clarify the scope of the assessment. State whether the quotation is required for one building, several buildings, a wider site or specific water systems. Include any areas that are managed separately, leased to another organisation or shared with other occupiers. A site-wide assessment may involve different responsibilities and control arrangements from an assessment limited to one occupied building.

It is also useful to explain what the assessment is expected to cover. For example, the requirement may be an initial assessment, a review of an existing assessment, or an assessment following changes to management arrangements or water services. If the work forms part of a wider compliance review, say whether related procedures and control records need to be considered. This prevents the quotation from being based on a narrower scope than the one required by the responsible person.

Describe the water system’s complexity. The assessor may need information about the number and arrangement of storage vessels, secondary return arrangements, calorifiers, point-of-use heaters, showers, spa or therapy facilities, process water systems and other risk-relevant equipment. Unusual installations, remote areas, long pipe runs, infrequently used outlets or systems that serve several buildings can require more investigation than a straightforward installation.

Provide any available schematic drawings, asset registers or commissioning information. They do not need to be perfect to be useful. Even an incomplete drawing can indicate whether further tracing or verification is likely to be needed during the survey. If no reliable drawings exist, mention this when requesting the quote, as producing or verifying system information may form part of the work rather than being an assumed part of a standard assessment.

Explain the site’s management arrangements. A quote should reflect who is responsible for the water systems and how duties are divided between the owner, landlord, facilities team, managing agent, tenants and contractors. Include details of any written control scheme, named responsible person, maintenance schedule, temperature monitoring process, flushing arrangements and escalation procedures where these are available. The assessor can then identify whether the required work is primarily a physical survey, a management review or both.

Records are particularly helpful when they show how the systems operate over time. Relevant documents may include previous risk assessments, monitoring logs, cleaning and disinfection certificates, inspection reports, maintenance records, defect reports, incident information and evidence of remedial work. Records should not be altered to make them appear complete. Gaps, inconsistent readings or missing documents are important information because they may need to be addressed in the assessment and recommendations.

Identify circumstances that may affect access or survey conditions. Tell the assessor about restricted plant rooms, controlled areas, tenant-only spaces, safeguarding requirements, security procedures, roof access, confined locations or equipment that cannot be inspected while the site is occupied. Also mention planned refurbishment, demolition, installation work or changes to the water services. These factors can affect the practical scope and whether certain parts of the assessment can be verified during the visit.

Information about known problems should be provided before the quotation is prepared. Examples include recurring temperature failures, poor flow, dead legs, leaks, corrosion, scaling, stagnant sections, failed components or concerns raised by staff or contractors. Reporting these issues does not replace the assessor’s inspection, but it helps ensure that the quote accounts for relevant areas rather than treating the site as a routine installation.

Confirm what the quoted fee is expected to include. Ask whether the price covers the site inspection, review of supplied documents, consultation with relevant personnel, written risk assessment, prioritised recommendations and presentation of findings. Establish whether water sampling, laboratory analysis, system schematics, follow-up visits, retesting, remedial design or contractor supervision are separate services. A Legionnaires’ risk assessment is not automatically the same as water testing or remedial work, so these elements should be identified separately.

The required report format can also affect the scope. A concise assessment for internal management may differ from documentation needed for multiple stakeholders, audit evidence, a property transaction, an insurer or a formal compliance review. State any required format, site-specific templates, reporting categories or deadlines when requesting the quotation, without assuming that additional documentation is included as standard.

Before accepting a quote, check its assumptions and exclusions. It should be clear which buildings, systems and records have been included, what information the client must provide, whether access is assumed to be available, and what would cause the price or scope to be reviewed. This is especially important where information is incomplete or the system has not previously been surveyed in detail.

Blue Fish Water Management Ltd can use the information supplied to define an appropriate legionella risk assessment scope and separate assessment work from related testing, compliance or remedial requirements. The more accurately the site arrangements and intended deliverables are described, the more useful the resulting quote will be for budgeting and compliance planning.
