# Care home Legionella evidence in England, Wales, Scotland and Northern Ireland

A care home can have the right water temperatures and still fail the inspection conversation if the evidence is scattered. The inspector is not there to redesign your pipework. They are trying to see whether the provider knew the Legionella risk, assigned responsibility, controlled it, and closed out defects.

That evidence question is clearest in England because CQC now publishes a specific Legionella risk-assessment document page for registration. The mistake is treating that CQC page as a UK-wide rulebook. Wales, Scotland and Northern Ireland have their own regulators and standards routes, but the practical evidence pack is recognisably the same: a current assessment, a written control scheme, monitoring records, remedial actions, and proof that vulnerable residents have been considered.

## What does not change between nations

The technical spine is still water safety. Care homes hold vulnerable people, aerosol-generating outlets, assisted bathrooms, TMVs, low-use rooms and a permanent scald-versus-Legionella trade-off. HSE's health-services guidance puts temperature control at the centre: hot water stored hot, hot distribution kept hot, cold water kept cold, infrequently used outlets flushed, and showerheads cleaned and descaled [2]. In Northern Ireland, HSENI gives the equivalent duty-holder route and adds a clear care-home scalding warning for vulnerable residents [3].

So the same core records matter everywhere:

- The current Legionella risk assessment, with the care home and all water systems named.
- The responsible person and deputy, with competence evidence.
- A schematic or asset list covering tanks, cylinders, showers, taps, TMVs, washers and any other water-using appliance.
- Temperature monitoring records, including sentinel outlets and any care-home-specific outlets selected by the assessment.
- Flushing records for void rooms, little-used en-suites, assisted bathrooms and closed wings.
- Showerhead and tap cleaning/descaling records.
- TMV inspection, servicing, cleaning and failsafe test records.
- Remedial-action logs showing who fixed what, when, and how it was verified.
- Staff training or local instruction for people expected to flush, record, report or escalate.
- Review evidence after changes in residents, rooms, plumbing, ownership, management or suspected cases.

The country difference is not the contents of the logbook. It is which regulator or standards document you point to when explaining why that evidence is enough.

## Four-nation regulator map

| Nation | Regulator route | What the Legionella file should show |
|---|---|---|
| England | CQC. CQC says a Legionella risk assessment is a legal requirement, assesses it under Regulation 12 and Regulation 15, and expects evidence of responsibility, actions, system identification, monitoring, controls, records, review and training [1]. | A CQC-ready evidence folder: current assessment, named responsible person, completed actions, temperature/flushing/shower/TMV records, action plan and review schedule. |
| Wales | Care Inspectorate Wales. Welsh care-home standards include water-temperature regulation and design solutions to reduce Legionella and hot-water/hot-surface risks [5]. | A CIW-ready premises and maintenance trail: assessment, safe water temperatures, scald controls, water checks, shower flushing/descaling and maintenance actions. |
| Scotland | Care Inspectorate. The adult and older-people quality framework examines whether the setting is safe and well maintained, and Care Inspectorate Hub resources signpost Legionella control and hot-water risk material for care settings [4][6]. | A Care Inspectorate-ready safe-setting file: assessment, maintenance, low-use outlet flushing, temperature/TMV evidence and closed remedial actions. |
| Northern Ireland | RQIA. RQIA publishes the care-home standards and legislation route; technical Legionella and scalding duties sit with HSENI guidance [3][7]. | An RQIA/HSENI-ready file: assessment, written scheme, monitoring records, scald controls for vulnerable residents, maintenance evidence and incident escalation contacts. |

This map deliberately avoids pretending each regulator has an identical Legionella page. England has the most explicit CQC registration document. Elsewhere, Legionella sits inside premises safety, health and safety, infection prevention, maintenance and care-home standards, supported by HSE or HSENI technical guidance.

## The evidence pack inspectors can actually read

Do not build the folder around certificates. Build it around decisions and records.

**Risk assessment and scheme.** The assessment should name the actual care home, not a generic template, and it should describe the systems residents can be exposed to: bathrooms, en-suites, showers, assisted bathing, laundries, kitchens, TMVs, tanks and low-use rooms. The written scheme should then say what is checked, by whom, how often, and what happens when a reading is out of range.

**Resident vulnerability.** A care home file should show that resident vulnerability shaped the controls. Scald protection is not an afterthought. The risk assessment should explain where TMVs are used, why they are close to outlets, how they are serviced, and how the home avoids creating long warm blended runs.

**Low-use controls.** Void rooms, hospital stays, closed wings and lightly used assisted bathrooms are a care-home-specific failure pattern. The evidence should show the room status, the flushing requirement, the dated flush, and the trigger before reoccupation.

**Action closure.** The biggest evidence gap is rarely the first bad reading. It is the unresolved action. A 48C hot outlet, a cold outlet that will not stay cold, a missing TMV service record or a showerhead cleaning gap should lead to an assigned action, a target date and a verification record. Without that closure, the file proves the home noticed risk and left it open.

**Review.** CQC's document expects to see annual review or earlier review after triggers such as water-system change, new residents, building alterations or suspected Legionnaires' disease [1]. Treat that as an England/CQC inspection expectation, not a universal replacement for L8's risk-based review duty. For any nation, a care home should be able to show that meaningful changes reopened the assessment.

## What to avoid saying

Avoid "CQC requires this" in Scotland, Wales or Northern Ireland. It is the wrong regulator. Say which regulator applies to the service, then use HSE or HSENI for the technical water-safety duty.

Avoid "we have a Legionella certificate" as if that settles the issue. A certificate without the assessment, monitoring records, TMV maintenance and action closure is weak evidence.

Avoid a one-size-fits-all review interval. A quiet residential home, a nursing home with clinical care, and a specialist service for highly vulnerable residents do not carry the same risk profile. The assessment sets the control detail, and the regulator-facing file should prove the site followed it.

## FAQ

### Is the CQC Legionella page relevant outside England?
It is useful as an evidence model, but it is not the regulator route outside England. Wales, Scotland and Northern Ireland have their own care regulators. Use the CQC page to understand the kind of records an inspector may expect, but cite CIW, Care Inspectorate or RQIA/HSENI for the actual service.

### Does a care home need a separate Legionella certificate?
No statutory certificate is the point. The useful evidence is the risk assessment and the records that prove the control scheme is live: temperature checks, flushing, showerhead cleaning, TMV servicing, remedial actions and review notes.

### Should a care home follow healthcare HTM guidance?
It depends on the care delivered. A home providing nursing or clinical care may sit closer to healthcare water-safety guidance than a residential home. The broader comparison is in [Healthcare water safety guidance across the UK](https://legionella.io/articles/healthcare-water-safety-guidance-across-the-uk-htm-shtm-whtm/), and the scald-versus-control detail is in [Legionella management in care homes and assisted living](https://legionella.io/articles/legionella-management-in-care-homes-and-assisted-living/).

## Next step

Build a one-page index at the front of the care home's Legionella file. It should list the regulator, the responsible person, the risk assessment date, the review trigger, the location of temperature records, flushing records, TMV records, shower-cleaning records and open actions. If any box points to "ask maintenance" or "contractor portal", the evidence pack is not inspection-ready yet.
