Legionella Risk Assessment in Merton
Book your Legionella Risk Assessment in Merton with a vetted professional — clear pricing guidance, certificates delivered digitally, renewal reminders included.
Straight answer
The legionella duty is real; the annual certificate isn't. Health and safety law requires landlords to assess where legionella bacteria could grow — stored warm water, stagnation, little-used outlets — and apply simple controls. The HSE has publicly warned against firms selling mandatory-sounding annual certification for ordinary rentals in places like Merton.
Booking

Live booking isn't switched on for Merton yet — vetting comes before listing, in that order. Leave your details and you'll get a straight answer by email: whether we can cover the property, when, and for how much. No obligation either way.
Paperwork
Assessments, reviews and tenant advice
File the written assessment with its date and the assessor's details, plus the tenant advice you issued — a short note on flushing unused outlets and keeping showerheads clean is itself a control measure worth evidencing. Add void-period flushing to your change-of-tenancy checklist and note it when done.
The inspection
What the assessor actually reviews
The assessment is a structured look at risk factors: water stored between roughly 20°C and 45°C, stagnation in unused outlets or dead-leg pipework, open tanks, spray at showers. Each factor found is paired with a control — temperature settings, flushing routines, descaling, insulation or removal of redundant pipe — and written up with the assessor's details and date.
Credentials
Who you're letting in
The tell for a trustworthy assessor is proportionality: a combi-boiler flat written up as low risk with simple controls, not a scare report recommending lab tests and yearly recertification. We verify training and insurance, and we're explicit with providers that mandatory-sounding certificate language is off the table.
Pricing
What a legionella assessment costs
The price tracks system complexity: combi-boiler flats sit at the bottom, properties with stored water, tanks and long pipe runs higher. Laboratory sampling is rarely needed for ordinary rentals and should never be a default line item. As everywhere on this site, the range is guidance — confirmed before booking.

Letting in Merton: the practical points
Water systems don't care about geography, so nothing about the duty is specific to Merton — but HMO licensing is local, and shared facilities raise the practical bar. London Borough of Merton may expect assessment evidence with licence paperwork, and larger stored-water systems in HMOs justify professional review.
The law
What the law asks of landlords in Merton
The duty sits under the Health and Safety at Work etc. Act framework and applies to residential landlords UK-wide; HSE guidance (ACOP L8 and HSG274) frames what suitable assessment and control mean. There's no prescribed certificate and no fixed review interval for simple domestic systems — review when something changes. Serious failures can be enforced by the HSE or London Borough of Merton and prosecuted, with fines set by the courts.
Landlords must assess and control the risk of exposure to legionella in their properties. For most ordinary domestic lets the assessment is simple, and the law does not require a certificate, an annual renewal, or testing of the water.
Penalties stated are statutory maximums or court-set; London Borough of Merton is the local housing authority for Merton.
FAQ
What Merton landlords ask us
What does the written assessment include?
A description of the water system, identified risk points, the control measures in place or recommended, tenant advice, and the assessor's details and date — your evidence that the duty has been considered properly.
Does an empty property increase legionella risk?
Yes — stagnant water in an unused system is the classic risk factor. Flushing all outlets thoroughly before a new tenancy starts is the standard control after a void period.
What simple controls reduce legionella risk?
Hot water stored at 60°C or above, cold water kept cold, flushing outlets after void periods, descaling and cleaning showerheads, and insulating or removing redundant pipework. The assessment records which of these apply to your property.
Do I need laboratory water sampling?
Rarely for ordinary domestic rentals. Sampling is a tool for higher-risk or complex systems, or where controls appear to be failing. A standard rental in Merton is normally evidenced by the risk assessment alone.
What if I ignore legionella duties?
The duty sits under the Health and Safety at Work etc. Act framework, so serious failures can be enforced by the HSE or London Borough of Merton and prosecuted, with fines set by the courts. In practice, risk to tenants and insurance exposure are the immediate concerns.
Are legionella duties different for HMOs?
The underlying duty is the same, but shared facilities, larger stored-water systems and licence conditions from London Borough of Merton raise the bar in practice — HMO landlords more often use professional assessments and periodic reviews as licence evidence.
