Legionella Testing for Care Homes & Healthcare Settings

Care homes, nursing homes, and healthcare facilities face the highest risk of Legionella outbreaks due to vulnerable residents and complex water systems. Regular testing is not just a legal requirement—it's essential for protecting the health and safety of residents and staff.

Professional testing for care homes: UKAS-accredited laboratory analysis from £39.95 plus VAT per sample. Typical care homes require 8-20+ samples depending on facility size and complexity. View care home pricing examples.

What we provide: Laboratory testing and certified results. We do not provide risk assessments, compliance advice, or remediation recommendations. For professional water hygiene advice specific to healthcare settings, consult a qualified water hygiene specialist or contact us and we can introduce you to one of our trusted partners.

Why Care Homes Are High Risk

Care homes present unique Legionella risks:

Vulnerable residents – Elderly people and those with weakened immune systems are at significantly higher risk of severe illness
Complex water systems – Multiple outlets, showers, baths, and dead legs create ideal conditions for bacterial growth
Variable water usage – Infrequently used outlets and periods of stagnation increase contamination risk
Temperature fluctuations – Difficulty maintaining consistent hot and cold water temperatures throughout large buildings
Assisted bathing equipment – Spa baths, whirlpools, and shower chairs create aerosols that can spread bacteria

Legal Requirements for Care Homes

Under the Health and Safety at Work Act 1974 and Control of Substances Hazardous to Health (COSHH) Regulations 2002, care home operators must:

Conduct a Legionella risk assessment
Implement a written control scheme
Appoint a responsible person to manage water safety
Monitor and test water systems regularly
Keep detailed records of all checks and tests
Review and update risk assessments annually or when changes occur

The Care Quality Commission (CQC) inspects care homes for compliance with water safety regulations. Regular testing provides evidence of ongoing water quality monitoring as part of your wider control programme.

How Many Samples Do Care Homes Need?

Sample requirements for care homes depend on your water system's complexity rather than the number of residents. A 20-bed home with multiple wings, assisted bathing suites, and aging pipework will need more samples than a newer 30-bed facility with a simple, well-maintained system.

Consider how many bathrooms have thermostatic mixing valves, whether you have spa baths or specialist bathing equipment, how many floors and wings your building has, and which rooms or outlets are rarely used. Cold water storage tanks and calorifiers also require dedicated sampling.

Your Legionella risk assessment should identify all sentinel outlets (the furthest points from your water source) and high-risk areas where vulnerable residents are exposed to aerosols from showers or baths.

Learn how to determine sample requirements for your facility.

Testing Frequency for Care Homes

We recommend:

Quarterly testing (every 3 months) for high-risk facilities
Bi-annual testing (every 6 months) for well-maintained systems with good control measures
Annual testing as an absolute minimum for compliance
Immediate testing after any system changes, repairs, or suspected contamination

More frequent testing provides earlier warning of problems and demonstrates robust water safety management to CQC inspectors.

What to Test in Care Homes

Priority sampling locations include:

Sentinel Outlets

Furthest taps from water source
Least frequently used outlets
Dead legs and rarely used rooms

High-Risk Areas

Assisted bathing suites and spa baths
Shower heads (especially thermostatic showers)
Kitchen taps and pre-rinse sprays
Laundry room outlets

Water Storage

Cold water storage tanks
Hot water calorifiers
TMV (thermostatic mixing valve) outlets

Understanding Your Test Results

Test results are reported in colony-forming units (CFU) per litre. For care homes with vulnerable residents, even low-level detection requires prompt action to protect resident health and demonstrate duty of care to CQC inspectors.

Results are typically available within 10-14 days. You are responsible for reviewing results against your risk assessment and determining necessary follow-up actions. Learn more about test result limitations and responsibilities.

CQC Inspections and Water Safety

The Care Quality Commission expects to see:

Up-to-date Legionella risk assessment
Written water safety control scheme
Records of temperature checks and flushing regimes
Evidence of regular water testing
Documented actions taken in response to test results
Staff training records on water safety

Failure to demonstrate adequate water safety management can result in compliance notices, enforcement action, or impact your CQC rating.
