Part F Ventilation Testing

Making sure your ventilation systems meet current air flow and compliance standards

Helping you achieve a more efficient performance from
your ventilation setup

Ventilation testing is essential for ensuring that your building’s mechanical ventilation systems are performing as designed and are delivering a safe, healthy indoor environment for your occupants. However, arranging for these works to take place can be time-consuming, especially for projects that require multiple compliance services.

This is where we can step in. Energy Digest will manage the entire ventilation testing process, from subcontractor coordination to certification. Our seamless service ensures compliance to Part F Building Regulations without disrupting your workflow, saving you time and money and enabling you to focus on other areas of your project without compromising your obligations.

FREQUENTLY ASKED QUESTIONS

Part F Ventilation Testing
FAQs

Airflow is measured using specialist equipment such as an anemometer or balometer at each ventilation outlet. These tools accurately assess the volume of air passing through the system to ensure it meets Part F Building Regulations requirements for adequate ventilation rates.

Yes, ventilation testing is often combined with services like air pressure testing or SAP calculations to streamline compliance processes. Coordinating these services reduces project delays and ensures all required assessments are completed efficiently.

Yes, local extraction units must still be tested to verify that they provide adequate airflow in line with Part F regulations.

Absolutely. Ventilation testing can highlight issues such as blockages, leaks, or improper installation in ductwork or vents. These errors can significantly impact airflow performance and energy efficiency, making the test essential for ensuring systems are functioning correctly.

If a system fails, a detailed report is provided outlining the reasons for this failure, such as insufficient airflow, blockages, or installation errors. Recommendations are given to rectify the issues, and follow-up testing can be conducted to confirm compliance.

Understanding Ventilation
Systems

Good ventilation is essential for fresh, healthy indoor air and compliance with Part F Ventilation Testing. 
 
Part F defines four systems:
 
1. System 1: Intermittent extract fans and background ventilators for residential use.
2. System 2: Passive stack ventilation.
3. System 3: Continuous mechanical extraction for wet rooms
4. System 4: Continuous mechanical ventilation with heat recovery (MVHR) systems for airtight homes, requiring commissioning.
 
Testing ensures ventilation systems perform as designed, maintaining air quality, efficiency and Part F building compliance.
