Legionella (Laboratory Test) review
Landlords or employers needing evidence for a Legionella risk assessment, spa or hydropool owners, and systems that have sat unused (holiday homes, stored hot water tanks, empty rental properties).

This is proper lab analysis, not a colour-change strip, so a result actually means something you can act on or show an inspector. It earns its place for statutory duty-holders and spa or hydropool owners, but it's the wrong tool for general reassurance about ordinary mains tap water.

- UKAS-accredited to ISO 17025 — a defensible result, not an indicative one
- Covers the full pneumophila group (serogroups 1 and 2–14), not just the headline strain
- Everything needed is included: bottle, instructions, and pre-paid next-day courier both ways
- 10–12 working day turnaround — no good if you need an answer today
- Single-determinand price is steep if you also want E. coli, lead or a broader panel
Who shouldn't buy this
Don't buy this to check whether your normal mains tap water is 'safe' — your water company already tests it to DWI standards. This is for landlords/employers with a legal duty, spa/hydropool owners, or a system that's been dormant, not everyday household peace of mind.
