Legionella Risk Assessments for Businesses
Helping businesses meet their legal obligations by connecting them with qualified legionella risk assessment providers across the UK.
Legionella risk assessments are a key part of managing health and safety in commercial and non-domestic premises. If your business controls water systems, you are legally required to identify and manage the risk of legionella bacteria.
Legionella Risk Assessment UK helps businesses find independent, qualified providers who understand commercial environments, regulatory requirements, and industry-specific risks.
For Businesses
What Is a Legionella Risk Assessment?
A legionella risk assessment is a structured evaluation of water systems within a property to identify potential risks where legionella bacteria could grow and spread.
For businesses, this typically includes assessing:
- Hot and cold water systems
- Water storage tanks and pipework
- Showers, taps, and outlets
- Low-use or infrequently used systems
- Cooling systems and plant equipment (where applicable)
The purpose is to identify risks and recommend proportionate control measures to reduce or manage them.
Which Businesses Need a Legionella Risk Assessment?
Most commercial and non-domestic premises require a legionella risk assessment, including:
- Offices and shared workspaces
- Retail and commercial units
- Hotels, guest accommodation, and leisure venues
- Care homes and healthcare facilities
- Educational buildings and nurseries
- Warehouses and industrial premises
- Public buildings and local authority sites
If your business has employees, visitors, or customers using water systems, a legionella risk assessment is likely required.
Legal Requirement for Businesses
Under UK health and safety law, businesses have a duty to assess and manage the risk of legionella bacteria.
This includes:
- Identifying potential sources of risk
- Implementing appropriate control measures
- Keeping records of assessments and actions
- Reviewing assessments regularly or when systems change
A suitable legionella risk assessment helps demonstrate compliance with these responsibilities.
Who Carries Out the Assessment?
Legionella risk assessments should be carried out by a competent person with appropriate knowledge, training, and experience.
Legionella Risk Assessment UK does not perform assessments. Instead, we connect businesses with independent providers who:
- Operate in your area
- Have experience with commercial premises
- Understand compliance and audit requirements
- Work across single or multi-site portfolios
How Often Do Businesses Need a Risk Assessment?
A legionella risk assessment should be reviewed:
- Regularly (typically every 1–2 years)
- When water systems are altered or extended
- When the use of the building changes
- If there is reason to suspect the assessment is no longer valid
Many businesses schedule periodic reviews as part of ongoing health and safety management.
