Legionella Risk Assessments

are a ‘cornerstone’ of health & safety. It’s important that yours is carried out in accordance with HSE guidance.

Legionella Risk Assessments are essential for ensuring that everyone is kept safe from the dangers associated with Legionella bacteria. With proper training & regular water risk assessments, organisations can reduce the chances of a Legionnaires’ disease outbreak occurring on their premises.

The Water Hygiene Centre is recognised as a leading provider of water safety consultancy services. This is demonstrated by the fact that we are one of a small number of organisations who can deliver UKAS accredited Legionella risk assessment [LRA] methods; which comply with ‘BS 8580 Water quality. Risk assessments for Legionella control. Code of practice’.

Identifying a company to carry out a water risk assessment should be relatively straightforward but how can you be sure that the service offered is fit for purpose and will help to discharge your legal obligations? The answer, increasingly, is accreditation. Our UKAS LRA's are accredited to ISO/IEC 17020:2012 and are compliant with the ACoP L8 and BS 8580. With this knowledge you can be confident that we have the technical expertise and management systems in place to undertake each Legionnaires' risk assessment competently, professionally and impartially.

Gaining our UKAS accreditation was challenging but has proven to be very worthwhile. Our LRA clients are safe in the knowledge that our assessments are more detailed and more consistent than ever due to the high standards required by UKAS along with the continual training and auditing of our own risk assessors.

Andy Gray, Huffkins

“Excellent performance and approach to water risk assessments that capture operational and management performance to truly understand the risks associated with water systems”.

David Fearn, Derbyshire Community Health Services NHS Foundation Trust

“The level of service received from The Water Hygiene Centre is delivered to an exceptional standard".

Paul Stephens, Wye Valley NHS Trust

“The service we received from the Water Hygiene Centre was second to none. As this was relatively new to myself, and me not being very knowledgeable on this subject should have made the assessments task very difficult. The assessor they sent over to carry out the assessment was incredibly patient with me, and assisted in explanations of all questions I threw his way. He made me feel at ease and was very forthcoming in sharing knowledge without question. Overall, was treated with high importance and respect. I would highly recommend the Water Hygiene Centre with confidence to anyone”.

Craig Gontier, Norman Piette Ltd

“Communicative and reliable service, thorough reports offering detailed recommendations in break down form that isuser-friendly for staff to read and implement”.
