What Is a Legionella Risk Assessment?
A Legionella risk assessment is a systematic inspection of your water system to identify conditions that could allow Legionella bacteria to multiply and present a risk of exposure. Our assessor will examine cold water storage tanks, hot water cylinders, pipework, showers, taps, and any other outlets where water could stagnate or reach a hazardous temperature.
Every hot and cold water outlet, storage tank, cylinder, and pipework run receives a thorough check — including areas prone to low usage or dead legs where bacteria are most likely to proliferate.
Hot and cold water temperatures are recorded at all key outlets. Because Legionella thrives between 20–45°C, any readings outside the safe range are flagged and documented in your report.
Following the visit, you receive a professional written report detailing all findings, a risk rating (Low / Medium / High), and a clear action plan. This document satisfies your legal duty as a landlord or employer.
Should remedial work be needed — such as tank cleaning, TMV servicing, or system flushing — our assessors can advise on the appropriate steps and, as qualified plumbers, carry out the work directly.
Your Legal Duty — Landlords & Employers in Southampton
Under the Health and Safety at Work Act 1974 and the Approved Code of Practice ACoP L8, duty holders must assess and control the risk of Legionella in any premises they own or manage. In practice, this covers residential landlords, HMO operators, commercial property managers, and employers throughout Southampton and Hampshire.
Even if you rent out only a single room in Southampton, you still carry a legal obligation to assess the Legionella risk in the water system and keep a written record of that assessment. Failing to do so can result in enforcement action, fines, or — in serious cases — prosecution.
Importantly, the HSE does not require landlords to carry out annual water sampling in most domestic settings. However, they do expect a documented risk assessment and regular monitoring. Our report gives you precisely what you need to demonstrate compliance to letting agents, councils, and HMO licensing teams.

How Long Does an Assessment Take?
A typical domestic risk assessment takes between 45 minutes and 1.5 hours, depending on the size and complexity of the property. During the visit, our assessor checks every water outlet, records temperatures, and inspects the cold water storage tank where present — documenting all findings as they go. As a result, there is no need for a follow-up visit in most cases. Your written report then follows within 3 working days.

Frequently Asked Questions — Legionella Risk Assessment Southampton
Yes. Under the Health and Safety at Work Act 1974 and ACoP L8, all landlords — including those renting a single domestic property — must assess the Legionella risk in their water system and maintain a written record. In addition, Southampton City Council and Hampshire HMO licensing teams expect this documentation to be in place before issuing or renewing a licence.
The HSE recommends reviewing your assessment whenever there is reason to believe it is no longer valid — for example, following significant plumbing works, a change of occupancy, or after a period of low usage. As a general guide, most residential rental landlords choose to reassess every two years, or whenever a new tenancy begins.
Your report will clearly identify any risks and include a prioritised action plan. Common findings include water heaters set too low, infrequently flushed outlets, or cold water tanks without a secure lid. Crucially, as qualified plumbers, our team can carry out any remedial work needed — including tank cleaning, temperature adjustments, and dead leg removal — without you needing to find a separate contractor.
Yes. The inspection is non-invasive and does not involve turning off the water supply. All our assessor needs is access to every water outlet, the airing cupboard or hot water cylinder, and the cold water storage tank if present. In most cases, tenants experience no disruption whatsoever. Alternatively, we are happy to attend between tenancies if that is more convenient.
