What Affects the Cost of a Business Legionella Risk Assessment?
Several factors influence pricing, including:
- Size and layout of the premises
Larger buildings or multiple floors typically require more time on site. - Water system complexity
Stored water tanks, extensive pipework, or specialist systems increase scope. - Type of business and occupancy
Public-facing premises and vulnerable occupants may require more detailed assessments. - Location
Regional pricing and travel requirements can affect cost. - Initial assessment vs review
First-time assessments often cost more than routine reviews.
Why Business Prices Are Higher Than Residential
Business assessments are typically more expensive than residential ones because they often involve:
- Larger or more complex water systems
- Higher usage levels
- Greater legal and compliance exposure
- More detailed documentation
- Audit and insurer requirements
For many businesses, a legionella risk assessment forms part of a wider health and safety management framework.
What Should Be Included in the Price
A suitable legionella risk assessment for businesses should normally include:
- Assessment of all relevant water systems
- Identification of potential legionella risks
- Consideration of building use and occupancy
- Written documentation or report
- Clear recommendations and review guidance
Businesses should be cautious of services that do not clearly outline what is included or fail to provide proper documentation.
Are Low-Cost Business Assessments a Risk?
Extremely low prices can sometimes indicate:
- Generic or template-based assessments
- Limited time spent on site
- Inadequate system review
- Poor or incomplete documentation
In the event of inspection, audit, or illness, businesses are expected to demonstrate that a suitable and sufficient assessment has been carried out.
Can Businesses Reduce Costs?
Businesses may reduce costs by:
- Combining multiple sites into one programme
- Scheduling assessments efficiently
- Maintaining accurate system records
- Carrying out regular reviews rather than repeat initial assessments
Working with providers experienced in commercial and multi-site environments can also help keep costs proportionate.
