What Block Managers Need to Know About Water Hygiene Compliance

If you manage a block of flats or a multi-unit residential site, you’re responsible for more than just the building’s structure. Water systems in shared buildings often include tanks, risers, and pipework that serve multiple units, and that brings extra responsibility for Legionella risk.

Shared systems, shared responsibility

Water safety in these environments can quickly become complex. Systems are often large, used inconsistently, and have multiple outlets that may not be flushed or maintained regularly. Without a clear water hygiene programme, the risk of contamination increases.

Why block managers are considered duty holders

Under UK law, the duty holder is the person in control of the premises. That includes block managers and managing agents who oversee communal areas and shared services.

You’re expected to assess the risk of Legionella across the whole system, take steps to control it, and document your actions clearly. This includes monitoring water temperatures, inspecting storage tanks, maintaining TMVs, and responding quickly to any signs of failure.

If the system isn’t managed properly and someone becomes ill, the legal consequences can be serious. That’s why compliance in this area isn’t optional — it’s essential.

Common risks in managed blocks

Risk often arises from low-use outlets in empty flats, oversized storage tanks, or poor system design. Shower heads that haven’t been cleaned, tanks without secure lids, or poorly insulated pipework can all contribute to conditions where Legionella can grow.

Flats that have been vacant for long periods also pose a higher risk if systems haven’t been flushed and maintained during that time. It’s not uncommon for these issues to go unnoticed until something goes wrong.
