At Aquatrust, we’re passionate about helping our customers protect their businesses, staff and customers through safe and compliant management of water quality. A huge part of what we do is helping customers prevent legionella through regular legionella risk assessments and ongoing water management.

It’s important to us to remain true experts in the world of water hygiene and legionella, which is why we’re proud to be members of the Legionella Control Association (LCA). Our membership reinforces our commitment to water safety and legionella prevention, so we wanted to take the time to tell you a little more about it.

What is the Legionella Control Association?

The Legionella Control Association was established at the request of the Health and Safety Executive (HSE) in 1999. The association is dedicated to raising the standards when it comes to keeping water systems safe from legionella. It still has close links with the HSE, as well as other public health authorities, and regularly participates in events that are concerned with the minimising of Legionnaires’ disease.

Legionella is a bacterium found in water. When people are exposed to dangerous levels, it can result in a potentially fatal form of pneumonia known as Legionnaires’ disease. Water systems that heat water and create spray or vapour, like showers, spas, saunas and swimming pools, are particularly at risk. We work closely with businesses and organisations to monitor their water systems and ensure they’re protected.

The Legionella Control Association shares our commitment to promoting legionella control. The association provides a code of conduct for service providers to follow, alongside membership requirements that must be met.

As well as LCA standards for members, the association promotes the following of external standards and guidance to ensure its members are aware of their legal obligations. This includes the Health and Safety at Work Act 1974 and all necessary British Standard documents.
