Pricing
What a legionella assessment costs
What you're paying for is a competent survey and a usable written report: system description, risk points, controls, tenant advice. Bundling the assessment with another visit to the property usually shaves the callout. If the property is genuinely simple and you understand the system, self-assessment is lawful — the fee buys documentation and assurance.
The law
Why Legionella Risk Assessment matters for Derry landlords
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 Derry City and Strabane District Council 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; Derry City and Strabane District Council is the local housing authority for Derry.
The inspection
What the assessor actually reviews
The assessor traces water from where it enters the property: any stored cold water, the cylinder or combi arrangement, pipe runs including dead legs, and every outlet — with showers getting particular attention as spray-formers. Temperatures are checked (hot storage at 60°C or above, cold staying cold), stagnation points noted, and the whole picture lands in a written report with photographs.
Credentials
Who you're letting in
Ask any water-hygiene assessor two questions: what standard do you assess against (the answer should reference HSE's L8 framework), and when would you recommend re-assessment (the answer should be about change, not a fixed 12 months regardless). Those answers, plus insurance, are our booking bar.
For landlords in Derry
Letting in Derry: the practical points
For a typical Derry rental the honest summary is: low risk, simple controls, one good written assessment, reviewed on change. Where that stops being true — tanks in lofts, long dead legs, sporadically occupied rooms, shared showers — is where professional assessment and Derry City and Strabane District Council's licensing expectations meet.
FAQ
Common questions about the Legionella risk assessment report
Are legionella duties different for HMOs?
The underlying duty is the same, but shared facilities, larger stored-water systems and licence conditions from Derry City and Strabane District Council raise the bar in practice — HMO landlords more often use professional assessments and periodic reviews as licence evidence.
Is a legionella risk assessment legally required for rentals in Derry?
Landlords across the UK have a duty under health and safety law to assess and control legionella risk. There is no statutory certificate and no fixed annual renewal — HSE guidance (ACOP L8) frames the duty as a risk assessment kept up to date, which for simple domestic systems can be a simple review.
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 makes legionella risk higher in a property?
Stored water between about 20°C and 45°C, stagnation in little-used outlets or dead-leg pipework, open cold-water tanks, and spray-forming outlets like showers. Combi-boiler properties with mains-fed cold water are generally low risk.
