Pay for the assessments you need

Every package produces the same evidence-backed record: room-by-room outlets, guided temperature readings, photo evidence, a PDF you can share and a public verification page.

One-off assessments start at £19.99. The suitability check, the water system guide and the sample report are free.

14-day money-back guarantee on your first paid report. If you're not satisfied, contact us within 14 days of purchase for a full refund. This does not affect your statutory rights.

See the report before you pay

A full example report, generated from a fictional assessment at 14 Example Street, Glasgow, G1 1AA and watermarked as a sample. Reference SAMPLE-LW-2026-0001. It is an example of the record you produce — not a certificate, and not a laboratory test.

The outcome up front: risk outcome, the reasons behind it and the suggested review date.
Every outlet room by room, including outlets excluded from measurement and why.
Hot, cold and blended temperature readings with the run time recorded for each.
Findings with the recommended actions written against the outlet they relate to.
Photo evidence, the signed declaration, the method, limitations and version stamps.

What does a Legionella risk assessment cost?

There is no single market price, because a Legionella risk assessment can be produced three different ways. Working from a blank template costs you nothing but your own time, and the quality depends entirely on how thoroughly you record the system, the outlets and the readings. A guided self-assessment tool sits in the middle: you still do the site visit, but the prompts, evidence capture and report are handled for you. Instructing a competent professional costs the most, and is the right answer for anything beyond a simple domestic system.

Beyond that, cost tracks complexity: whether hot water is stored or heated on demand, how many rooms and outlets there are, whether showers, tanks or little-used outlets are involved, and how many properties you need to keep current. One flat on a combi is a different job from a portfolio of houses with cylinders.

What it costs with LegionellaWise

LegionellaWise supports simple domestic water systems. Complex, communal or high-risk systems should be referred to a specialist — the app tells you when that applies.
