Cleanair UK provides expert hot and cold water system balancing for commercial and domestic buildings throughout the UK.
With regional teams in Kent and Birmingham, our engineers ensure water reaches every outlet at the correct temperature and in the correct time—protecting system performance, supporting compliance, and safeguarding the health of everyone who uses your building by eliminating Legionella growth risks.
Water temperature control sits at the centre of the UK’s legal framework for Legionella control. A poorly balanced system causes water stagnation within temperature zones where Legionella bacteria thrive, creating severe legal and health liabilities.
Cleanair UK’s engineers carry out water system balancing in strict alignment with CIBSE Commissioning Code W and BS 8558 standards:
We work across large-scale facilities including commercial offices, healthcare environments, schools, and multi-occupancy residential developments. We ensure compliance with complex circulation loops and stringent regulatory expectations.
Our engineers also support single-dwelling domestic properties. The core principles stay identical: maintaining correct flow, eliminating cold/hot spots, and ensuring zero stagnation to optimize energy efficiency and safety.
Every water balancing job is tracked outlet-by-outlet through our dedicated job management software. Flow rates, valve settings, and temperature verification data are compiled into real-time certificates accessible 24/7 via our client portal.
We deliver nationwide services across key sectors:
Balancing ensures hot water reaches every outlet quickly and at the correct temperature while keeping cold water cool. Without it, cooler sections or long wait times create conditions where harmful Legionella bacteria can multiply.
Yes, indirectly. Under COSHH 2002 and the Health and Safety at Work Act 1974, dutyholders must control Legionella risks. HSE guidance (ACOP L8 and HSG274) identifies temperature control via correct balancing as a required core control measure.
HSG274 Part 2 guidance mandates that hot water is stored at ≥60°C, circulating hot water returns at ≥50°C, and cold water stays below 20°C wherever reasonably practicable.
Yes. We carry out balancing for both domestic single dwellings and complex commercial or multi-occupancy systems, adapting our process to match each scale and regulatory framework.
Re-balancing should be conducted following pipework alterations, changes to building occupancy/usage, or whenever routine Legionella monitoring reveals temperature or flow issues.
Yes. Every job generates digital results suitable for inclusion in your Legionella Risk Assessment, Water Safety Plan, and O&M records, accessible anytime via our client portal.
Yes. Operating from regional offices in Kent and Birmingham, Cleanair UK delivers nationwide service coverage across the United Kingdom.
Every outlet. Right temperature. Right time. Ensure your hot and cold water systems are fully compliant and safe from Legionella risk. Contact our engineering team today on 0800 292 2400 or email info@cleanairuk.com.
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…
