If you own or manage a property in Cardiff or across South Wales, you have a legal responsibility to keep your water systems safe from legionella bacteria. At Clean Air UK, we provide professional legionella risk assessments in Cardiff to help you stay compliant, protect your premises, and safeguard everyone who uses your building.
Our Cardiff team works with businesses, rental properties, and public buildings, carrying out comprehensive assessments that identify potential risks, test your water systems, and recommend practical control measures.
Legionella bacteria thrive in hot and cold water systems where water temperature isn’t properly managed. When the bacteria spread through contaminated water droplets, they can cause Legionnaires’ disease — a severe form of pneumonia that can lead to serious illness or even death.
Carrying out a legionella risk assessment helps you identify high-risk areas, such as cooling towers, storage tanks, or dead legs, and put in place the right preventive measures to reduce the chance of legionella exposure.
Under the Health and Safety at Work Act and the Approved Code of Practice (ACoP L8), anyone who controls premises — including landlords, employers, and property managers — has a legal duty to assess and control the risk of legionella bacteria.
Failure to comply with these health and safety regulations can result in enforcement action, fines, or prosecution. Regular legionella risk assessments and water hygiene services are essential for staying fully compliant with the law.
Our legionella risk assessment process is straightforward and thorough, designed to minimise disruption while ensuring complete safety:
Our legionella control services cover every aspect of water safety — from testing and disinfection to cleaning and maintenance. We’ll help you manage water temperatures, improve water hygiene, and set up ongoing preventative measures to stop bacteria from returning.
Because each water system is different, our recommendations vary depending on your property’s design, use, and risk level. Whether you manage a single building or multiple properties across South Wales, we’ll tailor a plan that works for you.
Our Cardiff legionella risk assessors have extensive knowledge of local business needs and regulatory requirements. We’ve helped hundreds of clients across South Wales stay compliant, protect their staff and tenants, and reduce their exposure to legionella risks.
We’re known for our quick response times, clear guidance, and cost-effective services. Every assessment is carried out by qualified professionals who understand the importance of accuracy, safety, and reliability.
Protect your property and the people inside it with a professional legionella risk assessment in Cardiff. Our expert team will ensure your water systems are safe, compliant, and properly maintained — with practical advice you can trust.

Looking for companies for the cleaning and servicing of my kitchen canopy and ducts I found, via Google, overpriced local traders. I am so glad I looked on the BESA website and came across Clean Air Ltd. The lads you sent round were polite and did a good job. I was so confident in your pricing and work I recommended Clean Air to my church for their kitchen work. God Bless you all.
We got VIP treatment as a local business – all queries were answered professionally and the work itself was fast and clean – no mess left on site. A refreshing attitude! Thanks to the team!
Have used Cleanair before to do our kitchen deep clean and were very impressed with their work so asked them to replace our duct for the kitchen extraction. Arrived on time, done the work quickly and efficiently which allowed our kitchen team to carry on with their prep work. I highly recommend them.
A huge thank you to the staff at CleanAir UK who have done the most fantastic job cleaning our kitchen this year. They were prompt, polite, helpful, friendly and amazingly efficient. The kitchen is sparkling and we are thrilled with the results. We will definitely be asking them back next year…
