If you’ve recently installed an extract fan or mechanical ventilation system, you may need a Part F Ventilation Commissioning Certificate. This will ensure that your ventilation system is installed correctly and that you comply with the latest UK building regulations.
What is a Ventilation Commissioning Certificate?
A ventilation commissioning certificate is official proof that your extractor fan or mechanical ventilation system has been installed and is functioning correctly. It confirms that the system has been tested and meets the performance standards outlined in Part F of the Building Regulations (2010).
When Do You Need a Part F Certificate?
You’ll need a Part F Ventilation System Commissioning Certificate if:
- You have an extractor fan in your bathroom, kitchen, en-suites, or utility room.
- You have a Mechanical Extract Ventilation (MEV) system.
- You have a Mechanical Ventilation with Heat Recovery (MVHR) system.
Just note, if you have two separate fans in the kitchen and bathroom, you’ll need two separate extractor fan certificates.
What’s Included in the Certificate?
When you get a Part F commissioning certificate, it’ll include the following details:
- Your name and property address
- Type of ventilation system (e.g., extractor fan, MVHR), including serial number and model
- Commissioning engineer’s name, accreditation, and contact information
- Test instrument details, including calibration certificate information
- Installation checklist to confirm proper setup
- Airflow test results, showing the system meets the required extraction or supply rates
Airflow performance is the most crucial aspect of the document, as it demonstrates that the system meets regulatory performance benchmarks.
Who Can Issue a Commissioning Certificate?
Only a qualified and accredited engineer can issue a commissioning certificate.
- They must be BPEC-certified (or hold an equivalent qualification).
- They must use UKAS-calibrated equipment
Why is MVHR Commissioning Different?
If you have an MVHR (Mechanical Ventilation with Heat Recovery) system, then you’ll need to meet additional standards.
Alongside meeting Part F of the Building Regulations, you’ll need to meet the standards set by Part O of the Building Regulations (2021). This has benchmarks to reduce overheating in new residential properties.
Technicians do this through MVHR commissioning. It’s a comprehensive survey that covers airflow testing, system balancing, and visual and mechanical checks.
Conclusion
A Part F Ventilation Commissioning Certificate is a legal requirement to ensure your extract fan or mechanical ventilation system is installed and operating correctly.
Therefore, it doesn’t matter if you’re a homeowner tackling a DIY project or a building manager managing a new development; ensuring the installed system is tested and certified is mandatory.
