About Air Balancing & Commissioning
Independent air balancing and commissioning in the UK — grille-by-grille flow readings and CIBSE Commissioning Code A reports for new and existing systems.
Our air balancing & commissioning work in the UK is carried out to BESA TR/19 and SFG20 standards. We record pre- and post-clean surface deposit readings where applicable, airflow and static pressure, fan performance and access panel provision, and issue photographic evidence with every report.
We cover supply, extract and kitchen extraction ventilation, ductwork cleaning and installation, fire and volume control dampers, and system balancing for restaurants, hotels, schools, offices and industrial premises across the UK — scheduled out of hours where trading hours demand it.
Common issues include grease-laden kitchen extract ductwork, insufficient airflow and unbalanced systems, noisy or failed fans and belts, missing or inaccessible access hatches, blocked louvres and grilles, and damper faults that put you outside insurance and fire safety compliance.

What People Ask About Air Balancing & Commissioning
What is the purpose of air balancing?
The purpose of air balancing is to ensure that the correct amount of air is delivered to each space within a building, as specified in the HVAC system design. This process optimises airflow, enhances comfort, improves indoor air quality, and ensures the system operates efficiently, preventing hot or cold spots and energy waste.
How much does it cost to balance an AC system?
The cost for air balancing and commissioning an AC system starts from £450 + VAT per day. We provide fixed written quotes before any work begins, ensuring transparency. Our services include detailed grille-by-grille flow readings and comprehensive CIBSE Commissioning Code A reports to document the work.
What are the steps involved in the air balancing procedure for an HVAC system?
The air balancing procedure for an HVAC system typically involves taking initial airflow readings at all grilles, adjusting dampers and fan speeds to meet design specifications, and then taking final readings. This is followed by preparing a CIBSE Commissioning Code A report, documenting all findings and adjustments to ensure optimal system performance.
What is air balancing and commissioning?
Air balancing and commissioning is a specialised process that ensures an HVAC system is operating precisely according to its design specifications.
