Cleanair UK provides expert commissioning, balancing, performance validation, and design review services for mechanical ventilation systems in commercial, industrial, and residential buildings throughout the UK.
For building owners, contractors, and facilities managers, validation means confirming your system performs efficiently under real operating conditions, diagnosing underlying faults, and ensuring full regulatory compliance. With regional teams in Kent and Birmingham, our engineers ensure your ventilation system delivers exactly what it was designed to—and keeps performing over time.
Correct commissioning isn’t just good practice—it is required under UK building legislation and recognized industry standards. Missing or inadequate documentation can compromise indoor air quality and delay practical completion on site.
Cleanair UK’s engineers carry out comprehensive testing in strict accordance with CIBSE Code A and BSRIA BG 49 procedures:
Going beyond a snapshot balance, formal validation checks follow I.S. EN 14134:2019 standards to verify system performance under real operating conditions. We provide full fault-finding, efficiency diagnostics, and comparative testing to resolve airflow issues, condensation, and mold risks.
When an installed system fails to deliver, we evaluate the original design intent against actual building usage. We assess duct sizing, occupancy heat loads, and layout changes to provide practical, costed remedial solutions.
Every project is logged terminal-by-terminal through our dedicated compliance software, generating instant, real-time certification accessible 24/7 via our client portal.
We deliver nationwide services across key sectors:
Commissioning is the overall process of setting a system to work to design specification. Balancing adjusts dampers and fan settings so air reaches each terminal in correct proportions. Validation goes further by confirming ongoing efficiency under real operating conditions and diagnosing hidden faults.
Yes. Building Regulations Approved Document F requires mechanical ventilation systems to be commissioned, with test and commissioning certificates required by Building Control before signing off completion.
Common signs include stuffy or draughty rooms, inconsistent temperatures, high fan noise, or unexpected energy spikes. Layout, occupancy, or building fabric changes are also key triggers for performance validation.
Our engineers follow CIBSE Commissioning Code A and BSRIA BG 49 procedures, with measurement methods aligned to BS EN 12599 and I.S. EN 14134:2019 standards.

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…
