Legionella Testing
Professional Legionella Testing Across the UK
Legionella risk assessments and water testing for commercial premises and public sector buildings across the UK.
Electrical Testing UK carries out Legionella risk assessments and water sampling for businesses and public sector organisations. Legionella bacteria can proliferate in poorly managed water systems. As a result, they can cause Legionnaires’ disease, a potentially fatal form of pneumonia. Under the Health and Safety at Work Act 1974 and the COSHH Regulations 2002, duty holders have a legal obligation to assess and control this risk. Therefore our competent assessors carry out risk assessments to HSE Approved Code of Practice L8. Where required, we also take water samples for laboratory analysis. Finally, we provide clear written reports with prioritised recommendations.
Key Features Include

Risk Assessments to HSE ACoP L8
We carry out Legionella risk assessments to the standard required by HSE Approved Code of Practice L8 and Technical Guidance HSG274, providing documentation that demonstrates compliance to your insurer and enforcing authority.

commercial and industrial Assessments
We assess water systems in commercial rental properties, commercial premises and public sector buildings, with every assessment tailored to the specific water system, building type and occupancy.

Water Sampling and Laboratory Analysis
Where water sampling is required to verify control measures or investigate a potential Legionella problem, we take samples to the correct protocol and submit them to an accredited laboratory, providing results and recommendations on completion.

Clear Written Reports
Every assessment produces a clear written report identifying the hazards present, the people at risk, the control measures in place and any remedial actions required, with each action prioritised by urgency.

Ongoing Monitoring Programmes
We offer planned monitoring and re-assessment programmes for organisations that need to maintain ongoing compliance with their Legionella control obligations.
Legionella Risk Assessments and Water Testing for Every Type of Property
Legionella Risk Assessments for Commercial Premises
We carry out Legionella risk assessments for offices, hotels, gyms, leisure facilities and retail premises. In each case, we identify all water systems that present a risk. As a result, we provide a prioritised action plan where improvements are required.
Legionella Risk Assessments for Healthcare and Care Settings
Healthcare premises and care homes present the highest Legionella risk profile. Therefore we carry out assessments for NHS buildings, hospitals, care homes and supported living premises. Moreover, our assessors are experienced in HTM 04-01 requirements for healthcare water systems.
Legionella Risk Assessments for Schools and Educational Buildings
School water systems often have seasonal low usage, which favours Legionella proliferation. We assess schools, academies and further education colleges. As a result, we can recommend flushing regimes and control measures suited to educational occupancy patterns.
Legionella Risk Assessments for Local Authorities and Public Sector Estates
We manage planned Legionella assessment programmes for councils, housing associations and public sector organisations. This covers single sites and multi-site estates. In every case, we apply consistent methodology and consolidated documentation.
Legionella Water Sampling and Laboratory Testing
We take water samples from hot and cold water systems, showers, calorifiers and cooling towers using the correct protocol. We then submit them to an accredited laboratory. Finally, we provide results with clear interpretation and recommendations.
The Legionella Risk Assessment and Testing Process
What a Legionella Risk Assessment Involves
Our assessor visits your premises and carries out a systematic inspection of all water systems. We identify every component that could present a Legionella risk. This covers cold water storage tanks, calorifiers and hot water cylinders. It also covers all pipework, including dead legs and infrequently used outlets, plus showers, cooling towers and spa pools. In addition, we assess water temperatures, system design and the adequacy of existing control measures. As a result, we identify any conditions that could encourage Legionella proliferation.
What the Legionella Risk Assessment Report Contains
The written report describes the water systems assessed and identifies the significant findings and the people at risk. Moreover, it evaluates the existing control measures and their adequacy. It then sets out a prioritised action plan. We classify actions by urgency, so you can address the highest-risk items first. Where sampling is recommended, we also advise on the sampling points, frequency and protocol required.
How Often Legionella Risk Assessments Should Be Reviewed
HSE guidance requires the risk assessment to be reviewed regularly. You should also review it whenever it may no longer be valid. For example, this includes changes to the water system, building alterations, changes in occupancy or a suspected Legionella case. As a practical guide, most premises should be reviewed every two years, and higher-risk premises annually. Therefore we advise on the appropriate review interval for your premises as part of every assessment.
Why Businesses and Landlords Choose Electrical Testing UK for Legionella Testing
Competent Assessors With Specific Legionella Training
A competent person must carry out Legionella risk assessments, with sufficient knowledge of water systems and Legionella control. Our assessors have specific training and experience to HSE ACoP L8 and HSG274. Therefore they are not generalist engineers working outside their area of competence.
Clear Documentation That Satisfies the HSE and Insurers
We write our reports to a standard that satisfies HSE requirements and the expectations of commercial insurers. Moreover, every report includes a clear action plan with prioritised recommendations. As a result, you have the evidence needed to demonstrate that your Legionella control obligations are actively managed.
Assessment and Remedial Work Under One Contract
Sometimes the assessment identifies deficiencies in water system design or control measures. In these cases, Electrical Testing UK can carry out remedial work directly. This includes pipework modifications to eliminate dead legs, tank replacement and temperature control improvements.
Multi-Site Programme Management
Some organisations manage Legionella compliance across multiple properties. For them, we offer coordinated assessment and monitoring programmes. As a result, you receive consistent methodology, consolidated documentation and a single point of contact for the full estate.
