DS Water provides professional Legionella risk assessments and remedial works to help businesses comply with ACOP L8 regulations and protect building occupants from Legionnaires’ disease.

Our qualified engineers identify potential Legionella risks within your water systems and implement effective remedial solutions to eliminate hazards, reduce bacterial growth, and ensure full regulatory compliance.

We work with commercial buildings, landlords, healthcare providers, industrial sites, schools, and public sector organisations across the UK.

What is a Legionella Risk Assessment?

A Legionella risk assessment is a detailed inspection of your water systems to identify conditions that could allow Legionella bacteria to grow and spread.

Legionella bacteria can develop in:

• Stored water tanks
• Hot and cold water systems
• Pipework with poor circulation
• Calorifiers and water heaters
• Dead legs and redundant pipework

Following the risk assessment, remedial works may be required to bring your system into compliance and eliminate identified risks.

Why Are Legionella Risk Assessments Important?

Legionella risk assessments are a legal requirement under the Health and Safety at Work Act and ACOP L8 guidelines.

Carrying out regular assessments and remedial works helps you:

• Comply with UK Legionella regulations (ACOP L8)
• Protect staff, visitors, tenants, and building occupants
• Reduce the risk of Legionnaires’ disease
• Ensure your water systems operate safely and efficiently
• Avoid legal penalties and enforcement action

Duty holders, including landlords, employers, and building managers, are responsible for ensuring Legionella risks are properly assessed and controlled.

Legionella Remedial Works Following Risk Assessments

If your Legionella risk assessment identifies issues, our team can carry out all necessary remedial works to bring your water system up to standard.

Our remedial services include:
