Legionella risk assessment for Tattoo and piercing studios

Updated 12 September 2026

Tattoo and piercing studios are registered with the local authority for skin piercing, and registration inspections concentrate on infection control: sterilisation, single-use needles, surface cleaning. The water system duty under the Health and Safety at Work Act sits alongside that regime and is often missed precisely because studios are small and nobody thinks of them as having a water system to manage. They do, and the registration officer's inspection does not discharge it.

The typical studio has a handwash basin in or near each procedure room, a separate equipment sink where any reusable items are rinsed before sterilisation, an ultrasonic cleaner bath that is emptied and refilled regularly, and spray bottles used on skin and work surfaces. Hot water usually comes from a small point-of-use heater. The legionella-relevant features are the familiar ones: a second basin that only sees use when the studio is busy, a spray tap fitting that aerosolises at face height, and any stored water. Guest artists and convention booths sometimes work from portable handwash units that hold water in a warm room, and stored water like that needs the same attention as any tank, with regular changes and a record.

For a single studio the risk assessment is straightforward and can be done in-house with a structured template: identify each outlet, set weekly flushing for any basin used less than about once a week, descale spray fittings on a schedule, service any thermostatic mixing valve, and keep the records. The duty cannot be signed away to the landlord where the studio rents a room, so the assessment should note whose responsibility the wider building system is.

Is it legally required?

Tattoo and piercing studios in England and Wales are registered with the local authority under the Local Government (Miscellaneous Provisions) Act 1982, which covers hygiene and infection control for the skin-piercing activity itself. The legionella duty arises separately under the Health and Safety at Work Act 1974 and ACOP L8 as for any commercial premises, and is not discharged by the registration inspection.

Who is the duty holder?

The duty holder is whoever has control of the premises or the water system. For tattoo and piercing studios 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 tattoo and piercing studios 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 tattoo and piercing studios premises, that means at least every 24 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 tattoo and piercing studios premises typically costs between £100 and £300, 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).
