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.
