Here's the TL;DR
  • Proprietas automates the legionella risk register from certificates and tests — flags overdue actions, regenerates evidence on demand.
  • Manual L8 registers break at multi-site scale; the register is only as good as the last update.
  • No fixed legal “every X years” for all buildings — review on change and at sensible intervals (how often guide).
  • Digital, attributable trails beat Word docs last saved after a scare.

Every UK duty-holder needs a live legionella risk register — not a Word file last touched after a scare. This page gives you a legionella risk register template structure you can copy, the mistakes that sink audits, and how modern software keeps ACOP L8 evidence current.

High-impression search themes this supports: l8 risk assessment, l8 legionella risk assessment, legionella risk assessment frequency, how often should a legionella risk assessment be carried out, do I need a legionella risk assessment.

What changed in legionella compliance for 2026

  • Preference for near real-time monitoring and named ownership of sentinel outlets
  • Digital audit trails — who recorded what, when, from which document

Free legionella risk register template (copy this)

Use one row per asset/control point (or per building with linked sub-rows):

Five common mistakes

  1. One register for the whole group with no building filter
  2. Certificate date without open actions
  3. No named Responsible Person per demise
  4. Temperature logs in a paper book that never reach the register
  5. Review dates that never recalculate after material change

Frequently asked questions

Is a legionella risk assessment mandatory?
Where there is a risk of exposure under COSHH / ACOP L8 thinking, duty-holders must assess and control risk. See is it required / who can do it.

Is there a “legionella certificate”?
People say “certificate” for assessments and test reports. Treat the assessment + control scheme + records as the system of proof — not a single magic certificate.

Can software replace a competent assessor?
No. Software keeps the register live and attributable after the competent person has assessed risk.
