Tank inspections, temperature monitoring and TMV servicing on an L8 cycle.
Manage water hygiene and legionella control to ACoP L8 and HSG274: risk assessments, temperature monitoring and recurring tasks.
The duty
What Water & Legionella compliance involves.
The Approved Code of Practice L8 and guidance HSG274 require duty holders to assess and control the risk of legionella in water systems, with monitoring, inspection and record-keeping on a defined schedule.
CertFlow turns the L8 cycle into recurring tasks, captures temperatures and flushing on mobile, and keeps the risk assessment and monitoring history in one place.
Your legal duties
What the regulations require.
Legionella risk assessment
Duty holders must assess the risk of legionella in their water systems and keep the assessment under review, particularly after any change to the system or the way it is used.
Written scheme of control
Where a risk is identified, a written scheme of control must be prepared and put into practice, setting out the precautions and the monitoring needed to keep the risk under control.
Monitoring and record keeping
Temperature monitoring, inspections, flushing of little-used outlets and TMV servicing must be carried out on a defined schedule, with records kept to demonstrate control.
Appointed responsible person
A competent responsible person must be appointed to manage the scheme, and everyone carrying out the work must be suitably informed, instructed and trained.
How CertFlow handles it
From due date to defensible certificate.
Water & Legionella runs on the same platform as every other discipline, so the workflow, the registry and the audit trail are identical, whatever your team inspects.
Ready-to-issue templates
A built-in ACoP L8 report template, plus a drag-and-drop builder and bespoke PDF overlay for any client-specific form.
Automatic scheduling
Put every water & legionella asset on a recurring examination cycle. CertFlow generates the jobs and warns you before anything falls due.
Captured on site, offline
Readings, photos and signatures are captured in the field on mobile, fully offline, and sync the moment a connection returns.
Audit-ready proof
Every water & legionella certificate is filed in a searchable, exportable compliance registry with a full timestamped history.
From the field
What inspectors commonly find.
The defects and gaps that come up again and again on water & legionella inspections, the ones a good system helps you catch before an auditor does.
- No suitable legionella risk assessment, or one left unreviewed
- Sentinel and TMV temperatures out of the safe range or not monitored
- Dead legs and little-used outlets not identified or flushed
- No named, competent responsible person for the control scheme
- Monitoring and remedial records incomplete
Why it matters
Penalties & enforcement.
Failing to control legionella breaches the Health and Safety at Work Act and COSHH, with the approach set out in HSE’s ACoP L8. It can bring enforcement, prosecution and unlimited fines, alongside a real risk of serious or fatal illness.

Water & Legionella on CertFlow, answered.
What does ACoP L8 require?
That duty holders identify and assess the risk of legionella, prepare and implement a written scheme to prevent or control the risk, manage it properly, keep records and appoint a competent responsible person.
How often should water temperatures be monitored?
Sentinel outlet temperatures are typically checked monthly, calorifiers and storage tanks on defined cycles, and TMVs serviced at least annually, with the exact regime set by the risk assessment.
Who can carry out a legionella risk assessment?
A competent person with the right training and experience, often a registered legionella risk assessor. The assessment follows BS 8580 and the HSG274 guidance.
How does CertFlow manage legionella control?
CertFlow turns the L8 cycle into recurring tasks, captures temperatures and flushing on mobile, and keeps the risk assessment and the full monitoring history in one place.
Can CertFlow evidence control for an audit?
Yes. The full monitoring history, risk assessment and remedial actions are searchable and exportable, so control can be demonstrated the moment it is asked for.
