Legionella control for social housing & housing associations

Social housing and housing associations manage Legionella at scale, across large and diverse portfolios that mix individual homes, low-rise blocks, sheltered schemes and houses in multiple occupation. The legal duty to assess and control risk applies throughout, but the real difficulty is consistency: doing the right things reliably across thousands of properties and many shared communal systems.

Some tenants fall into higher-risk groups, and communal water systems in blocks and sheltered housing carry more risk than a typical single home. Voids between tenancies are a common stagnation point.

A workable approach is risk assessment proportionate to each property type, simple and repeatable controls, clear information for tenants, and central oversight of records across the whole stock. Managing logs across multiple sites in one place makes it far easier to show that assessments, reviews and routine tasks are actually being kept up to date.
