About Commercial Ventilation Repair
Commercial ventilation repair in the UK — extract fan failures, noisy ductwork, blocked grilles, leaking acoustic seals. Diagnosed and fixed first visit where possible.
Our commercial ventilation repair 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 Problems We Solve
Extract fan failures
Our engineers are experienced in diagnosing and repairing extract fan failures in commercial ventilation systems. We work efficiently to restore proper air circulation, ensuring your system operates effectively and maintains a healthy environment for your premises.
Noisy ductwork issues
Noisy ductwork can indicate underlying problems with your commercial ventilation system. Our skilled technicians identify the source of the noise, whether it's loose connections or airflow obstructions, and implement effective repairs to reduce disturbance and improve system performance.
Blocked grilles affecting airflow
Blocked grilles restrict proper airflow, compromising your ventilation system's efficiency. We clear obstructions and address underlying causes of blockages, ensuring optimal air exchange. This helps maintain indoor air quality and the comfortable operation of your commercial space.
Leaking acoustic seals
Leaking acoustic seals can lead to inefficiencies and increased noise levels in your ventilation system. Our experts diagnose and repair these leaks, restoring the integrity of your ductwork. This improves both system performance and sound insulation within your commercial building.
