Legionella Risk Assessment Sheffield
Professional Legionella risk assessments for residential landlords, HMOs, and commercial premises in Sheffield and South Yorkshire.
All residential landlords and commercial property owners in England have a legal duty to assess and manage the risk of Legionella bacteria in their water systems. Every Property Certificate Sheffield carries out professional Legionella risk assessments across Sheffield, Rotherham, and the wider South Yorkshire region — producing a full written report that satisfies the requirements of HSE Approved Code of Practice L8.
What Is a Legionella Risk Assessment?
Legionella bacteria occur naturally in the environment and can multiply to dangerous concentrations in water systems where temperatures fall between 20°C and 45°C — a range that poorly maintained hot and cold water systems can easily reach. Inhaling fine water droplets (aerosols) contaminated with Legionella can cause Legionnaires' disease, a serious and potentially fatal form of pneumonia.
A Legionella risk assessment identifies the specific features of a property's water system that could allow bacteria to proliferate — such as infrequently used outlets, dead legs in pipework, cold water storage tanks, or temperatures outside safe ranges. It documents the risks identified and the control measures in place to manage them. The assessment must be recorded in writing and reviewed regularly.
Following the inspection, we produce a full written report setting out the risks identified, the control measures currently in place, a risk rating, and any recommended remedial actions. The report satisfies the written record requirement under ACoP L8 and HSG274.
Who Needs a Legionella Risk Assessment?
The legal duty applies broadly to anyone who has control over premises with a water system. This includes:
- Residential landlords — All landlords letting residential properties have a legal duty to assess and manage Legionella risk. For simple properties with a combi boiler and regular occupancy, the risk is typically low — but the duty to assess and document still applies. Properties with cold water storage tanks, HMOs, or those that have been vacant are higher risk.
- HMO landlords — HMOs present elevated risk due to the number of occupants, more complex water systems, and the potential for infrequently used outlets. Local authorities may also require evidence of Legionella risk management as part of HMO licensing.
- Commercial property owners and employers — Any employer or person in control of commercial premises with a water system has a duty to manage Legionella risk. This applies to offices, warehouses, retail premises, hospitality, and any building with hot and cold water, cooling towers, or evaporative condensers.
- Property managers and letting agents — Agents managing properties on behalf of landlords should ensure Legionella risk assessments are in place across the portfolio. We work with letting agents and property management companies to provide assessments across multiple properties.
Can I do it myself? For the simplest domestic properties, the HSE confirms that landlords with sufficient knowledge can carry out the assessment themselves — provided it is recorded in writing. For HMOs, properties with storage tanks, or complex systems, a professional assessment provides better protection and a more robust written record.
Our Legionella Risk Assessment Service
Our assessors carry out Legionella risk assessments across Sheffield, Rotherham, Barnsley, Doncaster, Chesterfield, and surrounding areas. We assess domestic properties for residential landlords, HMOs, and commercial premises of all sizes.
Each assessment involves a physical inspection of the property's water systems — hot and cold — followed by a full written report. The report sets out the risks identified, a risk rating, the control measures in place, and any recommended remedial actions. You will receive the report once the assessment is complete.
We work with individual landlords, letting agents, and property management companies with larger portfolios. Portfolio clients can arrange account billing — contact our customer care team to discuss your requirements.
The Legionella risk assessment can often be coordinated alongside other property inspections — such as an EICR, Gas Safety Certificate, or Fire Risk Assessment — to minimise disruption to tenants.
