Legionella control for landlords & rental properties

Landlords letting residential property have a clear legal duty to assess and manage the risk of Legionella for their tenants, even though many domestic systems are relatively simple and low risk. The duty applies to a single buy-to-let just as it does to a large portfolio, and confusion about what is actually required is common.

There is no legal requirement for a 'Legionella certificate', and routine sampling is rarely needed in ordinary homes. What is expected is a suitable and sufficient risk assessment and sensible, proportionate control of the system, kept under review.

Typical domestic risk factors include void periods between tenancies, stored water in lofts, electric and stored-water showers, and infrequently used outlets. The practical answer is a proportionate assessment, simple control measures, clear information for tenants, and a record that the assessment has been done and reviewed.

What makes this setting different

  • The duty to assess applies to every let, however small
  • Void periods between tenancies allow stagnation
  • Stored water in lofts and electric showers add risk
  • Confusion over 'certificates' and unnecessary testing is common
  • Tenants should be given basic water-safety information
