About LegionellaCheck
LegionellaCheck is an independent information service that helps UK duty holders understand their obligations around legionella and water hygiene. Our audience is landlords, facilities managers, care home operators, school business managers, hotel operators, and anyone else who holds the legal duty to manage legionella risk.
We are not a water hygiene company. We do not carry out risk assessments, sell biocide, or provide legal advice. We research, explain, and simplify the rules so that you can make informed decisions about the water system in your premises.
What we cover
- Whether you need a legionella risk assessment and why
- What it should cover for your specific building type
- How much it typically costs
- The UK legislation, approved codes, and guidance that create your obligations
- Free templates and tools to help you discharge the duty
- What to do if a legionella sample comes back above the action threshold
