Legionella Risk Assessment Costs in the UK:
A Guide for Property Owners & Managers
If you’re a facilities manager, landlord, or property owner in the UK, understanding the cost of a Legionella Risk Assessment is a key part of managing your legal obligations and ensuring water safety. While annual or biennial assessments are not just best practice but often a legal requirement under health and safety regulations, budgeting for these essential services is crucial. This guide explores the factors influencing Legionella risk assessment costs and how Pipe Testing Services (PTS) provides transparent, value-driven solutions nationwide.
At PTS, we believe that ensuring safety and compliance shouldn’t come with hidden expenses. Our aim is to help you understand the investment involved in a thorough, compliant assessment, so you can achieve peace of mind effectively.
Understanding What Influences
Legionella Risk Assessment Costs
The cost of a Legionella risk assessment in the UK isn’t a one-size-fits-all figure. Several key factors determine the time, expertise, and resources required, which in turn affect the overall cost.
- Property Size and Water System Complexity: Naturally, larger premises with more intricate or extensive water systems will require a more detailed and time-consuming inspection. A small office building with a simple hot and cold water system might take a few hours to assess thoroughly. In contrast, a sprawling hospital complex, large industrial site, or multi-building residential portfolio could require several days of detailed evaluation by our qualified assessors.
- Type of Property and Water Usage: The nature of your property and how water is used significantly impacts the risk profile and therefore the assessment's scope. Buildings with more diverse water usage, such as healthcare facilities (requiring adherence to HTM 04-01), care homes, hotels with spa pools, or industrial sites with cooling towers, often necessitate more detailed assessments due to increased risk factors and the presence of vulnerable populations.
- Scope of Assessment: A standard visual inspection, temperature profiling of key outlets, and examination of stored water are core components. The number and type of water samples required for Legionella testing (if deemed necessary as part of the initial assessment or ongoing monitoring strategy by the assessor) can also influence costs, although sampling is more typically part of an ongoing control scheme rather than every initial assessment.
- Location and Accessibility: The geographical location of your property can affect overall pricing due to travel time and expenses for our inspectors. Additionally, the ease of access to all parts of the water system, such as cold water storage tanks or calorifiers, can influence the time taken on site.
- Competency of Assessor and Reporting Detail: A truly valuable assessment is conducted by a demonstrably competent person, leading to a comprehensive, actionable report compliant with ACOP L8. This level of detail and expertise is factored into the cost and provides genuine long-term value.
Typical Price Ranges for
Legionella Risk Assessments in the UK
While PTS provides bespoke quotations based on your specific site, it’s helpful to understand general market indicators. Simple assessments for very straightforward, small domestic-like properties might begin from around £90-£250. Medium-sized commercial properties or those with moderately complex systems could range from £300 to £1,000. Large, complex sites with extensive water systems, multiple buildings, or high-risk features like cooling towers may cost £2,000 or significantly more.
It is crucial to understand these are general indicators. The exact price will always depend on your property’s unique characteristics, system complexity, and the specific scope of the assessment required to meet ACOP L8 standards. Contact PTS for a tailored, transparent quotation.
Getting Value: Smart Approaches to Managing Assessment Costs
While managing expenses is important, compromising on the quality or thoroughness of your Legionella risk assessment can lead to much greater costs and risks down the line. True value comes from investing in a compliant assessment that genuinely helps you manage risk.
One key approach is to ensure a thorough initial assessment is conducted by a competent provider like PTS. This identifies all potential risks accurately, leading to proportionate and effective control measures, preventing costlier reactive work later. Implementing and maintaining robust Legionella monitoring and control measures, such as regular flushing and temperature checks as outlined in your risk assessment, can also help. Well-maintained systems and good record-keeping can sometimes streamline the process of future risk assessment reviews, making them more efficient. When seeking an assessment, always choose providers who can demonstrate their competence as qualified assessors to ensure the assessment is suitable and sufficient.

What to Avoid When Considering Legionella Assessment Costs
Certain “shortcuts” in an attempt to reduce immediate expenses can lead to greater risks, non-compliance, and significantly higher costs in the long term. It’s vital to steer clear of:
- Assessments Without Proper Training or Competence: The Duty Holder is legally responsible for ensuring the assessor is competent. Inadequate assessments can miss critical hazards, putting people at risk and failing to meet legal requirements.
- Unnecessarily Extending Assessment Intervals: While ACOP L8 recommends reviews at least every two years (or sooner if changes occur), significantly extending this without justification, especially in high-risk settings, is a false economy and increases risk.
- Neglecting Recommended Remedial Actions: An assessment will identify necessary Legionella Remedial Works. Delaying these actions can allow problems to escalate, leading to higher contamination levels and more extensive (and expensive) interventions later.
- Skipping Ongoing Water Treatment or Monitoring: Continuous effective management, as detailed in your monitoring plan, is vital, especially in facilities with vulnerable occupants or complex systems.

FAQs - Legionella Risk Assessment
Costs in the UK
How often do I legally need a Legionella risk assessment in the UK?
HSE ACOP L8 requires an initial assessment and then regular reviews. Best practice typically advises a review at least every two years, or more frequently if there are changes to the system, its use, new information on risks, or if control measures are failing.
Can I conduct a Legionella risk assessment myself to save money?
ACOP L8 mandates the assessment be carried out by a competent person. For most non-domestic properties or complex systems, this means engaging a trained professional with specific Legionella expertise. A DIY assessment for such properties is unlikely to be considered “suitable and sufficient” and could leave you non-compliant.
What are the penalties for not having a compliant Legionella risk assessment?
Failure to comply with health and safety law, including the requirement for a suitable risk assessment, can lead to enforcement action by the HSE or local authorities. This can include improvement notices, prohibition notices, significant fines, and, in severe cases, prosecution.
Does the cost of the assessment include any remedial works?
Typically, the initial quoted cost is for the Legionella Risk Assessment itself (survey, analysis, report). Any Legionella Remedial Works identified as necessary would be quoted separately, allowing you to make informed decisions.
How can I prepare for a Legionella risk assessment to potentially reduce costs or time?
Having up-to-date schematic drawings of your water systems, accessible records of maintenance and monitoring, and ensuring easy access to all parts of the water system (tanks, calorifiers, outlets) for the assessor can help make the process more efficient.
