Water hygiene use case

Legionella logbook software UK

A legionella logbook is only useful if it reflects the current water system, the written control scheme, completed monitoring and actions taken when results fall outside target ranges.

For UK landlords, employers, water hygiene contractors and facilities managers managing legionella control records and water monitoring.

Paper logbooks can work on a single site, but they become fragile where outlets, TMVs, tanks, flushing tasks, temperatures and remedials have to be evidenced across a portfolio.

CertFlow turns the water hygiene control scheme into scheduled tasks and records. It helps hold the evidence; it does not replace a competent legionella risk assessment or responsible-person judgement.

Honest fit

When Paper legionella logbooks is enough

  • You manage one simple site with a current risk assessment and well-controlled local logbook.
  • A responsible person reviews readings, missed checks and actions consistently.
  • You do not need contractor workflows, portfolio dashboards or mobile evidence capture.

Next step

Bring a sample asset list, certificate or inspection form. CertFlow can show how the workflow changes from first record to issued evidence.

From the field

What inspectors commonly see

  • Temperature logs completed but out-of-range readings not actioned.
  • Little-used outlets added to a site without a matching flushing schedule.
  • Risk assessment recommendations not translated into recurring checks.
  • TMV, tank or calorifier records held in separate contractor reports.
  • Responsible-person and competence evidence missing from the logbook.

Audit risk

Common mistakes

  • Treating monitoring as a tick-box exercise rather than evidence of control.
  • Keeping a generic schedule after the water system changes.
  • Not linking failed readings to corrective actions and rechecks.
  • Using a logbook that cannot show missed checks clearly.
  • Separating risk assessment, written scheme and monitoring history.

Evidence

Records to keep

  • Legionella risk assessment and written control scheme.
  • Outlet, sentinel, TMV, tank and calorifier asset records where relevant.
  • Temperature, flushing, cleaning and disinfection logs.
  • Out-of-range results, actions and recheck evidence.
  • Responsible-person appointment and competence records.

Questions

Legionella logbook software UK, answered.

Does CertFlow replace the legionella risk assessment?

No. A competent person should assess the risk and define the control scheme. CertFlow helps schedule and evidence the resulting checks.

Can failed readings create actions?

Yes. Out-of-range results can be recorded, assigned and tracked with evidence of follow-up.

Can contractors and facilities teams use the same records?

Yes. Site, asset and monitoring records can be held in one workflow so evidence is easier to retrieve.
