Water Hygiene Management in London: A Practical Compliance Checklist

London buildings often have mixed-use spaces, older pipework, roof tanks, basement plant, and irregular occupancy, so water hygiene management needs to be more than a yearly document review.

Start with a current legionella risk assessment that reflects the real site: every tank, calorifier, shower, TMV, little-used outlet, tenant area, and plant room should be accounted for.

The written scheme should name the responsible person, define temperature and flushing tasks, explain escalation limits, and make clear which tasks sit with your contractor and which remain in-house.

When comparing London providers, ask how quickly they can attend urgent control failures, what evidence appears in monthly reports, and whether recommendations are prioritised by risk rather than listed generically.

Use quarterly review meetings to check missed tasks, overdue remedials, repeat temperature failures, and any building changes that mean your assessment or control scheme needs updating.
