Legionella Risk Assessments in London
Landlords and those managing buildings have a duty to assess and control the risk of exposure to legionella bacteria in water systems. There is no single “legionella certificate”, but a proportionate risk assessment is the usual way to show the risk has been considered and controlled. We coordinate legionella risk assessments for letting agents, block managers and portfolio landlords across London.
What the assessment looks at
- Hot and cold water systems, tanks and water heaters
- Areas where water may stagnate, such as little-used outlets
- Temperatures and simple control measures
Who typically needs one
- Landlords of residential lets, including HMOs
- Managing agents responsible for communal water systems in blocks
- Owners of small commercial premises
How we help
- Send the addresses and a short description of each water system.
- We confirm scope and quote per property.
- A competent assessor visits and you receive a written assessment with any recommended controls.
We coordinate qualified providers; accreditation is held by the individual provider who carries out each inspection.
