Water Safety in Care Homes

Water Safety in Care Homes: Why Legionella Control Is About More Than Compliance

By Vantify’s Legionella Technical Manager

Working in a care home is a full-on job. Residents are there as they need constant support and supervision. These demands put huge strain on staff, who are often overworked and underpaid for the vital role they perform. In recent years, there’s been a notable increase in the use of agency staff meaning those unfamiliar with a home’s residents, policies and procedures are being expected to slot in seamlessly and maintain constant levels of care.

When it comes to health and safety, there is a lot to consider. Preventing falls and injuries, managing medications, maintaining food hygiene are just some of the things that immediately come to mind. However, one of the most significant health risks can exist behind the walls, above the ceilings and within the pipework of the care home itself.

Legionella bacteria is a serious threat to care homes and the Health and Safety Executive (HSE) has identified residents as a higher-risk population.  Older adults, individuals with underlying health conditions and residents with weakened immune systems are especially vulnerable to Legionnaires’ disease.

This bacterium thrives in warm and stagnant water and, in the right conditions, can multiply significantly within days. The challenge is that water safety failures rarely happen overnight. In my experience, the greatest risks are often created gradually through minor changes, ageing infrastructure and lapses in management arrangements that individually seem insignificant but collectively create the conditions for bacterial growth.

The Sector Is Changing

Historically, organisations viewed Legionella risk assessments as a compliance document that needed updating every few years. Leading operators are now taking a different approach and it’s important that care homes are part of this cohort.

Adopting a continuous management process that incorporates the following elements is the best way to prevent Legionella bacteria spreading:

• Governance.
• Monitoring.
• Training.
• Asset management.
• Record keeping.
• Planned investment.

This shift is critical because a Legionella risk assessment is only the starting point. Effective control depends upon implementing the recommendations, maintaining a suitable written scheme of control and regularly reviewing performance. Vantify’s water safety methodology is built around this principle, with assessments designed to review existing controls, management arrangements and ongoing compliance systems.

Why Care Homes Require Greater Vigilance

Unlike many commercial buildings, care homes present a unique combination of risk factors.

These often include:

• Vulnerable occupants.
• Stored hot and cold water.
• Multiple shower facilities.
• Assisted bathing equipment.
• Thermostatic mixing valves.
• Older infrastructure.
• Frequent room occupancy changes.
• Long pipe runs and little-used outlets.

The HSE guidance highlights that specialised considerations apply to healthcare and care home environments, including enhanced monitoring and water safety management arrangements.

For many providers, it is not the obvious risks that cause concern.

Instead, we frequently find:

• Redundant pipework retained after refurbishments.
• Infrequently used bedrooms.
• Incorrectly operating TMVs.
• Poor water turnover.
• Incomplete asset registers.
• Gaps in flushing records.
• Lack of ownership for corrective actions.

These are issues that can remain hidden for years unless there is an effective inspection and review process.

The Growing Importance of Governance

One trend we are seeing across the sector is increasing scrutiny of water safety governance. The Care Quality Commission has reinforced expectations around Legionella risk assessments, record keeping, training, monitoring arrangements and action management as part of safe care and treatment requirements.

Increasingly, regulators are not simply asking:

“Do you have a Legionella risk assessment?”

They are asking:

“Can you demonstrate that you are managing the findings?”

This distinction is important. A well-written assessment provides value only when organisations can demonstrate that recommendations are prioritised, tracked and completed.

The Biggest Emerging Risk: Building Change

One of the most underestimated Legionella risks within the care sector is change.

Buildings evolve continuously. Bedrooms are refurbished. Bathrooms are modified. Extensions are added. Equipment is replaced. Occupancy patterns change. Staff move on. More agency staff are used. Every one of these changes can alter the risk profile of the water system.

This is why Vantify places significant emphasis on managing the risk and reviewing assessments whenever there is reason to believe the original assessment may no longer remain valid, including system changes, operational changes and management changes.

The question should never be:

“How old is the risk assessment?”

Instead, it should be:

“Has anything changed since it was carried out?”

Beyond Legionella: A Whole-System Water Safety Approach

The highest-performing care home operators are moving beyond a narrow focus on Legionella and looking at other risks associated with water safety.

They are adopting a broader strategy that considers:

• Scalding risks.
• Water quality.
• Asset condition.
• Resilience of critical systems.
• Competence of responsible persons.

Healthcare-focused guidance such as HTM 04-01 promotes this wider water safety mindset and supports a structured management framework for higher-risk environments. For care providers, this offers a significant opportunity.

Good water safety management not only supports compliance; it contributes directly to resident wellbeing, operational resilience and confidence from regulators, families and stakeholders. Any family that has a relative in care wants to know their loved one will be looked after correctly and feel confident that every risk has been considered.

An Invisible Threat Mitigated by Unseen Measures

In fire safety, there is a saying that prevention is largely invisible because success means nothing happens. The same principle applies to Legionella control.

Residents will never see the monitoring checks, temperature records, flushing regimes or asset inspections being completed behind the scenes, but those activities are often the difference between a safe environment and a preventable outbreak.

The best care providers do not view water safety as a technical exercise; they view it as part of their duty of care. In a sector built upon protecting vulnerable people, that is exactly where it belongs.
