What is Legionella Monitoring?

Legionella monitoring involves routine checks of water systems to ensure that conditions do not allow Legionella bacteria to grow and spread.

Monitoring typically includes the regular testing and recording of water temperatures and inspections of outlets and system components. These checks help confirm that control measures identified in your Legionella risk assessment are working effectively.

Monitoring also helps organisations maintain the records required to demonstrate compliance with health and safety regulations.

Why is Legionella Monitoring Important?

Once a Legionella risk assessment has been carried out, duty holders must ensure that control measures are maintained over time.

Regular monitoring helps to:

  • Verify that hot and cold water temperatures remain within safe limits

  • Identify potential system faults or temperature issues

  • Prevent water stagnation and bacterial growth

  • Maintain accurate compliance records

  • Demonstrate compliance with HSE guidance

Without ongoing monitoring, water systems can quickly fall out of compliance, increasing health risks and potential legal liability.

  • Monthly temperature checks

  • Quarterly inspections of water outlets

  • Six-monthly tank inspections

  • Annual reviews of control measures
