Water Hygiene Management in London: A Practical Compliance Checklist

If you are responsible for a building in London, start with a current legionella risk assessment and confirm it reflects your actual plant and occupancy profile.

Make sure a written scheme of control exists, has named dutyholders, and sets clear monitoring frequencies for sentinel outlets, calorifiers, and tanks.

Ask prospective contractors how they evidence remedial actions and escalation when control limits are breached.

Build a monthly review rhythm that checks monitoring logs, flushing records, and training status for responsible persons.

When comparing providers, prioritise competence, reporting quality, and response times over lowest cost alone.
