Do I need Legionella Control?


Legionella is a clever bacteria that can be found in any water system including systems with or without cold water storage tanks. There are many reasons why Legionella grows in a water system, these include: areas of little use allowing water to stagnate, temperatures between 20-50°C, nutrients such as debris, limescale, foreign bodies. Materials that encourage growth such as rusted steel, rubber, and lead. Non water regulations advisory scheme (WRAS) fittings that do not comply water regulation standards to name a few. This means that whether you have one or two hundred sinks, or you have mains water supply, a combi boiler and no tank, that you still need a legionella risk assessment as all water systems have the potential to breed harmful bacteria such as legionella, E.coli, coliforms and the like.

Our best advise is that control and prevention is better than the cure. Beat Legionella by controlling and preventing growth, avoiding expensive and unnecessary remedial works and disinfections. By undertaking a risk assessment, remediating the risks found, and undertaking your monitoring requirements set out by the HSE, in the HSG 274 part 2, you’ll help minimise the risk of exposure to Legionella and avoid expensive reactive works to remove Legionella by taking action before grows.

Legionella and Legionnaires’ Disease


Legionella is a common bacterium found in natural environments including ponds, rivers and lakes. The bacteria can also be supplied in small counts within mains water supply. Where there is water and the conditions of creating water droplets (aerosol), people using or within the area of these services may be at risk.

Legionnaires’ disease is a form of pneumonia, which can be fatal. The most at risk are the very old and the very young, the ill and smokers to name a few. Legionella bacteria can also cause other, less harmful illness such as Pontiac fever and Lochgoilhead fever, which can affect all people.

The main route of infection is through inhalation, by inhaling airborne water droplets that contain Legionella. It cannot be spread from person to person. The majority of cases or outbreaks of the disease have been via domestic water services, evaporative cooling towers, and spa pools.

Legionella Testing Kit


uRisk offers a fantastic self testing kit available to buy at £45.00+VAT and delivery charges, to test for Legionella bacteria yourself quickly and efficiently. The Legionella testing kit is an easy and inexpensive DIY kit to help you become legally compliant. Ordering a legionella testing kit means you can carry out the water sampling in your own time without the need of an engineer’s visit. Along with the testing kit we will send you full instructions on how to test correctly and all testing kit samples will be checked in UKAS accredited laboratories for the most accurate results possible. You will then receive your results as well as a certificate for your legionella control records.
