I have used Greenovation on several occasions and have had great results. James has always been extremely helpful and works with you to ensure a positive outcome. I will definitely continue to use Greenovation for air leakage testing and mechanical flow rate tests and am happy to recommend them to anyone.

Steve Davies

Greenovation have completed air pressure testing across numerous new build housing sites for me for a regional residential builder across Shropshire, Staffordshire & Cheshire. Booking in is never a problem – usually with short notice and tight deadlines to achieve Part L building regulations for CML dates which Greenovation are always helpful to accommodate.

    What is Flow Rate Testing?

    Clear the Air: The Importance of Air Flow Rate Testing for Healthy Environments and Efficient Ventilation Systems.

    Ventilation flow testing is a crucial process that evaluates the performance of extractor fans, including intermittent extract fans. It measures the airflow rates generated by these fans to ensure they effectively remove pollutants, moisture, and odors. By assessing the ventilation system’s capacity, accuracy, and efficiency, testing helps identify any issues and enables necessary adjustments for optimal airflow, improved indoor air quality, and a healthier environment.

    Why Do I Need A Vent Test?

    By measuring and analyzing airflow rates, it ensures that the fans are operating at optimal levels, effectively removing contaminants and maintaining proper air circulation. Accurate flow rate testing helps identify potential issues like insufficient airflow, fan malfunctions, or inadequate ventilation, allowing for timely adjustments and improved indoor air quality, energy efficiency, and overall comfort.

    Minimum Extract Flow Rates Explained:

    To ensure effective ventilation, extractor fans must achieve minimum extract flow rates. These rates are determined based on industry standards and regulations. The minimum benchmark method is a widely used approach to establish these flow rate requirements.


    The benchmark method involves calculating the minimum extract flow rate based on factors such as room size, intended use, and occupancy. It takes into account specific guidelines and recommendations provided by relevant regulatory bodies. These benchmarks serve as a reference point for evaluating the performance of extractor fans and their ability to maintain adequate airflow and ventilation in different settings.


    Meeting the minimum extract flow rate requirements is crucial for maintaining proper air quality. At Greenovation, we specialize in extractor fan flow rate testing, ensuring that your ventilation systems meet and exceed the minimum extract flow rate benchmarks.
