Why disinfect hot and cold hot water supply systems?

Legionella testing and risk assessment North London

The primary methods for controlling Legionella and other bacteria in hot and cold water systems is temperature and the movement of water. Where this cannot be reliably achieved or if remedial works have been carried out, chemical disinfection may be required.

Chemical disinfection is a process used to remove or kill micro-organisms;the process can also reduce their number to a non-hazardous level. A micro organism is an organism of microscopic size and includes bacteria, algae, fungi and viruses.

One of the most publicised forms of bacteria affecting cold and hot water systems, occasionally with fatal consequences, is Legionella. This is a type of aerobic bacterium (i.e. requires oxygen unlike anaerobic bacterium) which is commonly found in environmental waters but can grow to high numbers in warm water (20 – 50°C).

Given the right ‘chain of conditions’ from entering a water supply system to being inhaled by a susceptible human, the Legionella bacteria can develop into Legionnaires’ disease, a form of pneumonia that can cause serious illness or even death.

Landlords - You now have a legal obligation to test for Legionella

If you have a rental property or rent out a room in a house, even though it may carry a low risk from legionella, landlords must still carry out a Legionella bacteria risk assessment.

While there is no legal legionella test certificate required by the Health and Safety Executive (HSE), landlords must still be able to prove that they have correctly risk assessed their property and are controlling any known risks to keep their tenants safe.

Who can perform the risk assessment

HSE states in its official guidance document that a competent person must be "appointed to carry out the risk assessment and draw up and implement precautionary measures". Although the competent person could be the landlord or letting agent (if they have the relevant training and experience), it is usually performed by an independant fully qualied professional such as Peter Brown Plumbing.
