Extract Fan Testing / Commissioning
Professional Part F compliance testing and commissioning services for residential and commercial buildings
What is Extract Fan Testing / Commissioning?
Extract fan testing and commissioning is a mandatory requirement under Part F of the Building Regulations for all new build and refurbishment projects. This essential service ensures that mechanical ventilation systems are properly installed, balanced, and performing to specification.
My extract fan testing service involves comprehensive measurement and adjustment of ventilation systems using a UKAS calibrated Balometer with a hood to ensure they meet the required air flow rates, noise levels, and efficiency standards. This includes testing individual fans, balancing the entire system, and providing detailed commissioning reports for building control compliance.
Part F Building Regulation Requirement
Extract fan testing is mandatory for all new builds and major refurbishments. Building control will not approve completion certificates without proper commissioning documentation. My testing ensures full compliance with Part F requirements and provides the necessary certification for your project handover.
My 6-Step Testing Process
1. Initial Assessment
I conduct a thorough inspection of your ventilation system, checking fan locations, ductwork routing, and control systems to ensure everything is properly installed and accessible for testing.
2. System Preparation
I prepare the building for testing by ensuring all windows and doors are closed, internal doors are open, and any temporary seals are removed to create accurate testing conditions.
3. Individual Fan Testing
I test each extract fan individually using a UKAS calibrated Balometer with a hood to measure air flow rates with precision, ensuring each fan meets the specified performance requirements for its designated area.
4. System Balancing
I balance the entire ventilation system using the UKAS calibrated Balometer to ensure optimal performance, adjusting fan speeds and damper positions to achieve the required air flow distribution throughout the building.
5. Noise Level Testing
I measure noise levels from all ventilation equipment to ensure they comply with Part F requirements and don't exceed acceptable noise limits for occupied spaces.
6. Commissioning Report
I provide a comprehensive commissioning report with all test results, compliance certificates, and recommendations for ongoing maintenance to ensure continued performance.

Frequently Asked Questions
How long does extract fan testing take?
Most extract fan testing takes between 2-4 hours, depending on the number of fans and complexity of the system. This includes individual fan testing, system balancing, and initial report preparation.
What happens if my fans don't meet the required flow rates?
If fans don't meet the required flow rates, I'll identify the issues and provide recommendations for improvement. Common solutions include:
- Adjusting fan speeds and damper positions
- Cleaning or replacing filters
- Repairing or replacing damaged ductwork
- Upgrading undersized fans
I can arrange a re-test once improvements have been made.
Do I need to prepare the building before testing?
Yes, some preparation is required:
- Ensure all fans are accessible and operational
- Close all windows and external doors
- Open all internal doors
- Remove any temporary covers or seals
- Ensure power is available to all fans
I'll provide detailed preparation instructions when booking your test.
What equipment do you use for testing?
I use UKAS calibrated equipment that meets British Standards, including:
- UKAS calibrated Balometer with hood - Primary air flow measurement device
- Digital manometer for pressure measurement
- Sound level meter for noise testing
- Duct pressure testing equipment
- Specialised balancing tools
Can testing be done in occupied buildings?
Yes, extract fan testing can be conducted in occupied buildings. The process is non-invasive and doesn't cause any damage. Occupants may notice temporary changes in air flow during testing, but this is normal and expected.
How much does extract fan testing cost?
Costs vary depending on the number of fans and system complexity. Contact me for a personalised quote based on your specific requirements. I provide competitive pricing with no hidden costs and clear timelines for delivery.
