All employers are required by law to assess the risk posed by the potential for legionella colonisation. This is detailed under the legislation in the Health and Safety Work Act (1974) and the Control of Substances Hazardous to Health Regulations (1999).


Enviroliance offers extensive and compliant Legionella Risk Assessments of man-made water systems to identify any potential risks present, together with the control measures required to deal with them. Risk assessments should be carried out regularly on water systems that are at risk of harbouring harmful bacteria.

A reasonably foreseeable risk of Legionella bacteria exists in buildings with Hot and Cold water systems, Spa facilities, Cooling Towers and any equipment containing water that produces an aerosol or spray.

Risk assessments provide Employers with confidence that their systems are safe for use and pose no threat to the surrounding environment. The assessment also ensures that any control measure already in place is effective in maintaining low levels of bacteria for the long term.

At Enviroliance, our team is fully accredited to conduct high quality risk assessments on site to protect our clients and their employees from exposure to legionella bacteria.

The assessment involves a comprehensive investigation into the design and intended use of the water systems particularly areas of risk where the bacteria may be present. The Assessment will also consider manamgement and maintenance records in line with the owner/occupier legionella control policy.

Following inspection of the site, the findings of the inspection are comprised into a written record for our clients and will include the following:

  • Level of risk present
  • Non-conformities in line With Health & Safety Legislation and Industry Guidance
  • Recommended Control Procedures
  • Recommended Remedial Actions
  • Schematics of Site Water Systems
  • Photographs of Site Assets and Identified Risks

Enviroliance as standard will also produce a bespoke site systems logbook for on-going monitoring and maintenance of the water systems on site.

Are you concerned about the risk of Legionella within your organisation? Or has significant time elapsed since your last risk assessment?

At Enviroliance we are dedicated to helping organisations keep employees, customers and other stakeholders safe through consistent and effective water systems and legionella control management.
