We follow a strict Health and Safety Executive Approved Code of Practice, carrying out regular inspection and water safety testing of shared water systems in blocks of flats. In individual homes, the risk of legionella is minimal.
Legionella is a bacterium which can grow in stored or stagnant water under certain conditions.
Inhalation of infected spray or droplets or water vapour can result in Legionnaire’s disease. This is a type of pneumonia which may be mild and flu-like, but can become more serious, and sometimes fatal. Early treatment with the correct antibiotics is effective in most cases.

Water cylinders and tanks are renewed frequently, so bacteria does not have the opportunity to grow. However, we do still advise taking the following precautions:
