What does a Legionella risk assessment involve?

Our comprehensive and compliant Legionella risk assessments include the identification and evaluation of all potential sources of risk associated with Legionella within your building’s water system.

A City and Guilds-qualified Legionella risk assessor visits your premises to perform a site survey. This involves:

  • A detailed inspection of each room
  • Water temperatures taken across the site measured against acceptable ranges
  • Identification and detailed inspection of all site assets
  • Trace of all pipe work configurations and water sources
  • Identification, evaluation and prioritisation of all risks
  • Control scheme recommendations against the identified risks
  • Check of system materials to ensure compliance with WRAS (the latest water fittings regulations)
  • Photography of all site assets and risk areas

Following the site visit, the risk assessment is typed up and issued to you electronically and/or in hardcopy depending on your requirements. This includes:

  • Certification of the risk assessment - appropriate for any HSE inspection
  • Overall risk rating - a quantitative way to measure risk and prioritise remedial works
  • Executive summary - a summary of findings and recommendations for initial review
  • Recommendations - a task-by-task summary of all recommendations bespoke to site
  • Site and asset inspection reports - Asset registries, useful for management records
  • Report photography - All findings clearly referenced against photographic record
