Legionella risk assessment for Funeral homes

Updated 12 September 2026

Funeral homes combine a near-domestic building with one unusually wet, high-hygiene workspace. Most premises are converted houses or small purpose-built chapels with an office, viewing rooms, staff welfare facilities and a mortuary, and the mortuary is where the water risk concentrates: body-washing facilities, sluice sinks, hosing-down points and, in embalming rooms, preparation equipment that connects to the water supply. Water use is irregular in a way that invites stagnation — a preparation room can be in constant use one week and stand idle the next, and the viewing room washbasin may be used only a handful of times a month.

Backflow protection matters more here than in almost any other small premises. Water that could be contaminated in a mortuary environment is treated as a fluid category 5 risk under the Water Fittings Regulations, the highest category, so hose points and preparation equipment need properly maintained air gaps or mechanical backflow protection, and those devices belong on the inspection list. Hosing down a mortuary floor also generates spray, so the cleanliness of the supply feeding it is not an abstract concern. The rest of the system — the kitchenette, the toilets, the washbasin in the chapel of rest — is managed like any small commercial system: hot water reaching 50°C at outlets, cold below 20°C, and weekly flushing of anything that sits idle.

The duty holder is the funeral business, whether an independent or a branch of a national group, and it cannot be delegated to the embalmer or the premises contractor. A written risk assessment, a short written scheme naming the little-used outlets, and a flushing log are usually the whole of what a small funeral home needs — but they need to exist and be kept up to date.

Is it legally required?

Funeral businesses are employers and occupiers of commercial premises under the Health and Safety at Work Act 1974, so the standard ACOP L8 and HSG274 framework applies. In addition, the Water Supply (Water Fittings) Regulations 1999 treat contamination risk from mortuary and undertaker premises as fluid category 5, which drives the backflow protection required on hose points and preparation equipment. Where the business is a branch of a larger group, the duty still sits with the operating company, not the individual premises manager.

Who is the duty holder?

The duty holder is whoever has control of the premises or the water system. For funeral homes premises, this is usually the employer, owner, landlord, or managing agent. The duty cannot be contracted out: you can hire a water hygiene consultant, but the legal responsibility still sits with you.

What the assessment should cover

ACOP L8 sets out five things a suitable and sufficient assessment must do:

1. Identify and assess sources of risk across the whole water system, including stored hot and cold water, dead legs, rarely used outlets, and any equipment that generates aerosols
2. Produce a written scheme for preventing or controlling the risk, with specific tasks, temperatures, and frequencies
3. Implement, manage, and monitor the scheme in practice, not just on paper
4. Keep records of the assessment, the scheme, monitoring results, and any remedial action taken
5. Appoint a competent person (often called the "responsible person") to be accountable for the scheme

Specific water system risks to check

For funeral homes premises, assessors typically pay close attention to:

• Hot water storage temperatures (calorifiers must reach 60°C throughout)
• Hot water distribution temperatures (50°C within one minute at outlets)
• Cold water storage tank condition, lid seal, and temperature (below 20°C)
• Dead legs, redundant pipework, and little-used outlets
• Shower heads, flexible hoses, and thermostatic mixing valves
• Any cooling tower, evaporative condenser, or spa pool (these are notifiable to the local authority under the Notification of Cooling Towers and Evaporative Condensers Regulations 1992)

How often to review

There is no fixed legal interval, but ACOP L8 requires that the assessment is reviewed regularly and whenever there is reason to believe it may no longer be valid. For most funeral homes premises, that means at least every 12 months and sooner after any of the following:

• Changes to the water system (new pipework, fittings, equipment)
• Changes to the use of the building or the number of occupants
• A positive legionella test result or a case of Legionnaires' disease linked to the premises
• Prolonged periods of low occupancy or system shutdown (a risk during holidays, term breaks, or refurbishment)
• New guidance from HSE

Typical cost

A professional legionella risk assessment for funeral homes premises typically costs between £200 and £500, depending on the size of the building, the number of water outlets, and whether there are any cooling towers or evaporative condensers (these add significantly to the cost because of the statutory inspection regime).
