# Legionella in village halls, churches and community buildings

Yes — a village hall, parish church or scout hut needs a Legionella risk assessment, even when it is run entirely by volunteers and open only a few hours a week. The legal duty sits with whoever controls the building: the trustees, the management committee, or the Parochial Church Council. Most of these buildings are genuinely low-risk, so the controls are modest and cheap. What catches them out is rarely exotic. It is water sitting still in the pipes between bookings.

## Why the duty applies to a volunteer-run hall

The law that covers Legionella doesn't ask whether anyone is paid. If a charity opens its premises to the public, hires the hall out, or employs even a part-time cleaner, the people in control of those premises carry the same kind of duty as any employer: identify and assess the risk from the water system, control it, keep records, and appoint someone responsible for the job [1]. HSE makes the point most plainly in its guidance for landlords, whose plumbing is often no more complicated than a small hall's — a simple system still needs a proportionate assessment, not a thick report [2][5].

## The real risk: low occupancy, not complex plant

A hospital has cooling towers and miles of pipework. A village hall has a kitchen, some toilets, maybe an accessible-toilet shower, a water heater and possibly a cold tank in the loft. The hazard is not complexity. It is the pattern of use. Legionella multiplies in warm, still water — roughly the 20–45°C band — and a building that stands empty from Sunday afternoon to Thursday evening gives it exactly that [3][4].

Stagnation is the thread running through almost every community-building problem. Water that doesn't move warms up, loses any residual disinfectant, and lets bacteria settle into the scale and biofilm inside taps and shower heads. The mechanism is the same one set out in [Neglected water systems: the danger of stagnation](https://legionella.io/articles/neglected-water-systems-the-danger-of-stagnation/), just on a smaller scale. Seasonal closures make it worse: a scout hut shut for the summer, or a hall with no winter bookings, can sit unused for weeks at a stretch. Managing those gaps is the subject of [Seasonal buildings: managing intermittently used properties](https://legionella.io/articles/seasonal-buildings-managing-intermittently-used-properties/).

## Who is the duty holder — and who actually does the work

In a charity-run hall, the duty holder is usually the trustees or management committee as a body. In a Church of England church it is normally the PCC; other denominations have an equivalent governing group. That body should name one person — often a trustee, the booking secretary, or a churchwarden — as the responsible person who keeps the assessment current and makes sure the flushing actually happens. Getting the split between the legal duty and the practical role right matters, and it is explained in [Duty Holder and Responsible Person roles in Legionella management](https://legionella.io/articles/duty-holder-and-responsible-person-roles-in-legionella-management/). The common failure in volunteer settings is simpler than any of that: everyone assumes someone else is doing it.

## The same risk in three different buildings

The hall used three evenings a week plus weekend parties has the most outlets and the most aerosol risk — a kitchen, a cleaner's sink, an accessible-toilet shower that gets used twice a year. The parish church with a single cold tap in the vestry and no hot water at all is close to the lowest risk there is; its assessment can be short, but it still needs writing down. The scout hut, open one evening a week in term time and locked all summer, is the classic intermittent case: fine in October, a stagnation problem by September if nobody flushed it. Same bacteria, same controls, scaled to each.

## The handful of controls that actually matter

You don't need a treatment plant. For most community buildings the work is flushing, a few temperature checks, sensible attention to anything that makes a spray, and a record that you've done it. HSE advises flushing infrequently used outlets, with the frequency set by your risk assessment; for a building empty for days at a time, a weekly flush of every tap and any shower is a common starting point [3]. The method is in [Flushing little-used outlets: best practices](https://legionella.io/articles/flushing-little-used-outlets-best-practices/). Showers and spray taps deserve the most attention because they make the breathable aerosol Legionella travels in, so descaling and disinfecting the heads periodically earns its place — and if your hall has no shower at all, you have removed a whole category of risk [3].

### A walk-round checklist for a small community building

Use it once to map the building, then keep the routine items going and write down what you do.

Map what you have:
- Walk the building and list every tap, the kitchen, the toilets, any shower, outside taps, the water heater or cylinder, and the cold-water tank in the loft if there is one.
- Flag every outlet that is rarely used — the accessible-toilet basin, a cleaner's sink, an outside tap, a urinal in a hall that now mostly hosts toddler groups.
- Spot dead legs: capped pipes to a removed boiler, a disconnected urinal, an old water softener still plumbed in. Getting them cut out removes the risk for good.

Keep the risk down:
- Flush little-used taps and any shower until the water has run fully through, at the frequency your assessment sets (weekly is a sensible default for buildings that sit empty for days).
- Run the kitchen and toilet taps before a large booking if the hall has been shut for a while.
- Check that stored hot water is hot and cold water is cold a few times across the year [4].
- Descale and disinfect shower heads and spray taps on a set schedule.
- After a long closure, flush the whole system through before you reopen.

Write it down:
- Keep a simple logbook: date, task, who did it.
- Hold the risk assessment with the hall's papers and review it whenever the building or its use changes.
- Name one responsible person so tasks don't fall between volunteers.

## A note on scope

This is general guidance to help a committee understand the shape of the duty, not a substitute for a site-specific assessment by someone competent to make the judgement for your building. The proportionate approach in BS 8580-1 means the assessment matches the effort to the real risk [5]: for a single-tap vestry that may be a page; for a hall with showers and a stored hot-water system it will be more. We are not offering legal advice, and nothing here is medical guidance — if you think anyone may have been exposed or made unwell, that is a matter for a doctor and, where relevant, your local authority.

## Common questions

### Do we have to pay a company, or can a trustee do the risk assessment?
For a simple building, a trustee or volunteer can carry out the assessment if they are genuinely competent — they understand the system and the controls. If no one is, or if there are showers and stored hot water, bringing in an assessor for a one-off survey is usually money well spent, and you keep the routine flushing in-house [1][2].

### Our church has one cold tap and no hot water — does any of this apply?
Yes, but lightly. A single, regularly-used cold tap is about as low-risk as a water system gets. You still record that you have assessed it; the main action is to flush it if it goes unused for a stretch, and to reassess if anything changes — a new water heater, a kitchenette, an installed shower [2].

### Do we need to send water samples to a lab?
Usually not. Routine Legionella sampling is not generally required for simple, low-risk hot and cold water systems, and your risk assessment decides whether testing would add anything [1]. Most community buildings get far more value from reliable flushing than from a one-off test result [3].

## Your next step

Block out half an hour this week for one trustee to walk the building with a notepad and list every outlet, marking the ones nobody has used in months. That list is the start of your risk assessment, and the rarely-used outlets it reveals are exactly where a community building's risk hides. From there, set a flushing routine and write down the first entry.
